Description

本発明は、箱状部材の製造方法に関し、詳しくは、第1部材と第2部材とを接合することにより箱状部材を製造する箱状部材の製造方法に関する。   The present invention relates to a method for manufacturing a box-shaped member, and more particularly to a method for manufacturing a box-shaped member that manufactures a box-shaped member by joining a first member and a second member.

従来、この種の箱状部材の製造方法としては、断面を略コ字形状に折り曲げ加工することにより形成した上面板と断面を略コ字形状に折り曲げ加工した側面板とを用いてタンクを形成するものが提案されている(例えば、特許文献1参照)。この製造方法では、上面板と側面板とを組み付けてタンク状とし、接触部を溶接することによりタンクを形成している。   Conventionally, as a method of manufacturing this type of box-shaped member, a tank is formed using a top plate formed by bending a cross section into a substantially U shape and a side plate formed by bending the cross section into a substantially U shape. Have been proposed (see, for example, Patent Document 1). In this manufacturing method, the top plate and the side plate are assembled into a tank shape, and the tank is formed by welding the contact portion.

しかしながら、上述の箱状部材の製造方法では、板材の折り曲げ加工の他に溶接が必要となるため、作業工程が多く、大量生産する場合には不向きとなる。特に、小型の箱状部材を形成する場合には、細密な作業を必要とし、生産性が低下してしまう。また、溶接の精度によっては隙間が生じ、密閉性が低下する場合も生じる。   However, the above-described method for manufacturing a box-shaped member requires welding in addition to the bending process of the plate material, so that there are many work steps, which is not suitable for mass production. In particular, when a small box-shaped member is formed, a fine work is required, and productivity is lowered. Further, a gap may be generated depending on the accuracy of welding, and the sealing performance may be reduced.

本発明の箱状部材の製造方法は、密閉性の高い箱状部材を簡易に且つ迅速に製造することを主目的とする。   The manufacturing method of the box-shaped member of the present invention is mainly intended to easily and quickly manufacture a box-shaped member having high hermeticity.

本発明の箱状部材の製造方法は、上述の主目的を達成するために以下の手段を採った。   The manufacturing method of the box-shaped member of the present invention employs the following means in order to achieve the main object described above.

When the box-shaped member is assembled with the first member so that the cross-section is U-shaped using the metal plate material, the U-shaped end surface of the first member is the second surface of the second member. 2 so that the metal contacts the surface of the bonded or plated plate, or the U-shaped end surface of the second member contacts the surface of the first member bonded or plated. Forming the second member;
The box-shaped member is assembled by the first member and the second member, and in this state, the second metal is brazed using a furnace having a temperature higher than the melting point of the second metal and lower than the melting point of the first metal. The box-shaped member is manufactured by brazing as
This is the gist.

この本発明の第1の箱状部材の製造方法では、金属板材を用いて第1部材と第2部材とを形成する。第1部材と第2部材は、箱状部材を組み付けたときに一方の部材のコ字形状の端面が他方の部材の第2金属が接合またはメッキされた板面に当接するように形成する。そして、第1部材と第2部材とにより箱状部材を組み付け、これを金属板材の第2金属の融点より高く第1金属の融点より低い温度の炉に入れることにより、第2金属をロウ材として用いてロウ付けし、箱状部材を完成する。金属板材を用いているから、組み付けた箱状部材を炉に入れるだけで箱状部材を製造することができる。また、第1部材と第2部材は箱状部材を組み付けたときに一方の部材のコ字形状の端面が他方の部材の板面に当接するから、接合部の密閉性を高くすることができる。これらの結果、密閉性の高い箱状部材を簡易に且つ迅速に製造することができる。ここで、「端面」は、金属板材の切断面を意味している。また、「コ字形状の端面」としては、全体として「コ」字の形状の端面を意味しており、一部に凹部や凸部,切り掛け,突起を形成したものも含まれる。   In the first method for manufacturing a box-shaped member of the present invention, the first member and the second member are formed using a metal plate material. The first member and the second member are formed such that when the box-shaped member is assembled, the U-shaped end surface of one member abuts the plate surface on which the second metal of the other member is bonded or plated. Then, the box-shaped member is assembled by the first member and the second member, and the second metal is brazed by placing it in a furnace having a temperature higher than the melting point of the second metal of the metal plate and lower than the melting point of the first metal. And brazing to complete a box-shaped member. Since the metal plate material is used, the box-shaped member can be manufactured simply by putting the assembled box-shaped member into the furnace. Moreover, since the U-shaped end surface of one member contacts the plate surface of the other member when the box-shaped member is assembled, the first member and the second member can improve the sealing performance of the joint portion. . As a result, a box-shaped member with high hermeticity can be manufactured easily and quickly. Here, the “end face” means a cut surface of the metal plate material. The “U-shaped end surface” means an “U” -shaped end surface as a whole, and includes a part formed with a concave portion, a convex portion, a hook, or a protrusion.

こうした本発明の第1の箱状部材の製造方法において、前記第1部材の前記第2部材に対向する面にスリットを形成し、前記金属板材を用いて、幅が前記スリットの幅、長さが前記箱状部材を形成したときに前記第2部材に当接する長さ、となる第3部材を形成し、前記第1部材と前記第2部材とを組み付けて前記箱状部材を組み付け、前記第1部材の前記スリットに前記第3部材を挿入端が前記第2部材に当接するように嵌挿し、この状態で前記炉を用いてロウ付けすることにより、前記箱状部材を製造する、ものとすることもできる。第3部材は、第2部材との当接面で第2部材とロウ付けされ、第1部材のスリットの端面とロウ付けされる。このため、第3部材は箱状部材の内部で第1部材と第2部材とに接合する壁として機能する。この結果、箱状部材の強度を高くすることができ、製造された箱状部材に内圧を作用させたときの箱状部材の変形を抑制することができる。この場合、前記第2部材の前記第3部材が当接する部分に前記第3部材の挿入端が嵌合する溝を形成し、前記第1部材と前記第2部材とにより前記箱状部材を組み付け、前記第1部材の前記スリットに前記第3部材を挿入端が前記第2部材の前記溝に嵌合するように嵌挿し、この状態で前記炉を用いてロウ付けすることにより、前記箱状部材を製造する、ものとすることもできる。こうすれば、第3部材の第2部材への位置決めを容易に行なうことができる。   In such a first box-shaped member manufacturing method of the present invention, a slit is formed on a surface of the first member facing the second member, and the width is the width and length of the slit using the metal plate material. Forming a third member having a length that contacts the second member when the box-shaped member is formed, assembling the first member and the second member, and assembling the box-shaped member, The box-shaped member is manufactured by inserting the third member into the slit of the first member so that the insertion end comes into contact with the second member and brazing using the furnace in this state. It can also be. The third member is brazed with the second member at the contact surface with the second member, and brazed with the end surface of the slit of the first member. For this reason, the 3rd member functions as a wall joined to the 1st member and the 2nd member inside a box-shaped member. As a result, the strength of the box-shaped member can be increased, and deformation of the box-shaped member when an internal pressure is applied to the manufactured box-shaped member can be suppressed. In this case, a groove in which the insertion end of the third member is fitted is formed in a portion of the second member where the third member abuts, and the box-like member is assembled by the first member and the second member. By inserting the third member into the slit of the first member so that the insertion end fits into the groove of the second member, and brazing using the furnace in this state, the box shape The member can be manufactured. If it carries out like this, positioning to the 2nd member of a 3rd member can be performed easily.

Forming a third member so as to have a length greater than or equal to the length between the outer wall surface of the surface on which the first slit is formed and the outer wall surface of the surface on which the second slit is formed, The box-shaped member is assembled by the first member and the second member, and the third member is fitted into the first slit of the first member and the second slit of the second member. And brazing using the furnace in this state Manufacturing the box-shaped member may be a thing. The third member is brazed to the end surface of the first slit of the first member and brazed to the end surface of the second slit of the second member. For this reason, the 3rd member functions as a wall joined to the 1st member and the 2nd member inside a box-shaped member. As a result, the strength of the box-shaped member can be increased, and deformation of the box-shaped member when an internal pressure is applied to the manufactured box-shaped member can be suppressed. Moreover, since the third member is fitted into the first slit and the second slit, the third member can be easily positioned.

As a result, a box-shaped member with high hermeticity can be manufactured easily and quickly. In addition, since the plurality of first members are aligned in parallel without gaps so that the openings face in the same direction, the wall surfaces of the first members that contact each other function as walls formed inside the box-shaped member. As a result, the strength of the box-shaped member can be increased, and deformation of the box-shaped member when an internal pressure is applied to the manufactured box-shaped member can be suppressed.

底面部材50は、クラッド板材により、長さが頂面部材30の頂面の幅と同一になるように、底面の幅が頂面部材30の長さにクラッド板材2枚分の厚みを加えた長さになるように、底面の側面の高さが頂面部材30の側面の高さにクラッド板材1枚分の厚みを加えた長さになるように、全体として断面がコ字形状に形成されている。したがって、底面部材50に頂面部材30を開口部が対向するように組み付けると、頂面部材30のコ字形状の端面38a,38bが底面部材50の側面の内側の縁部板面58a,58bに当接すると共に、頂面部材30の両側面の端面38c,38dが底面部材50の底面の内側の縁部板面58c,58dに当接する。   The bottom member 50 has a width of the bottom surface added to the length of the top member 30 by the thickness of two clad plates so that the length of the bottom member 50 is the same as the width of the top surface of the top member 30. The cross section is formed in a U-shape as a whole so that the height of the side surface of the bottom surface is equal to the height of the side surface of the top surface member 30 plus the thickness of one clad plate material so as to be the length. Has been. Therefore, when the top member 30 is assembled to the bottom member 50 so that the opening faces the U-shaped end surfaces 38a and 38b of the top member 30, the edge plate surfaces 58a and 58b on the inner side of the side surface of the bottom member 50 are used. And end surfaces 38c and 38d on both side surfaces of the top surface member 30 abut on edge plate surfaces 58c and 58d inside the bottom surface of the bottom surface member 50.

また、底面部材50の底面の中央の頂面部材30に形成されたスリット32に整合する位置には、長さがスリット32の長さと同一になるように、幅がクラッド板材の厚みとなるように、位置決め溝52が形成されている。したがって、底面部材50に頂面部材30を組み付けて、スリット32に後述する壁部材50を挿入すると、壁部材50の挿入端が位置決め溝52に嵌合することにより、壁部材50の位置決めを行なうことができる。   In addition, the width is the thickness of the clad plate material so that the length is the same as the length of the slit 32 at a position matching the slit 32 formed in the top surface member 30 at the center of the bottom surface of the bottom surface member 50. In addition, a positioning groove 52 is formed. Therefore, when the top member 30 is assembled to the bottom member 50 and a wall member 50 described later is inserted into the slit 32, the insertion end of the wall member 50 is fitted into the positioning groove 52, thereby positioning the wall member 50. be able to.

さらに、底面部材50の両側面の中央には内側に凸の浅い溝56a,56bが形成されている。こうした溝56a,56bを側面に形成することにより、溝を形成しないものに比して側面の剛性を高くすることができる。また、底面部材50の一方の側面(図2中右手前の側面)の溝56aの両側には、2つの貫通孔54a,54bが形成されている。この2つの貫通孔54a,54bは、箱状部材20の内側への流体の流入口や流出口となる。   Further, shallow grooves 56 a and 56 b that are convex inward are formed in the center of both side surfaces of the bottom member 50. By forming such grooves 56a and 56b on the side surfaces, the rigidity of the side surfaces can be increased as compared with those not forming the grooves. Further, two through holes 54a and 54b are formed on both sides of the groove 56a on one side surface of the bottom surface member 50 (the side surface on the right front side in FIG. 2). The two through holes 54 a and 54 b serve as an inflow port and an outflow port for fluid to the inside of the box-shaped member 20.

壁部材60は、クラッド板材により、幅が頂面部材30のスリット32の長さと同一になるように、高さが頂面部材30の側面の高さに位置決め溝52の深さを加えた長さと同一になるように、全体として矩形形状に形成されている。したがって、底面部材50に頂面部材30を組み付けてスリット32に壁部材50を挿入すると、壁部材60の挿入端は底面部材50の位置決め溝52に嵌合し、壁部材60の挿入端とは反対の端面は頂面部材30の頂面と同一面となる。また、壁部材60には、複数の貫通孔62a〜62dが形成されている。   The wall member 60 is a length obtained by adding the depth of the positioning groove 52 to the height of the side surface of the top surface member 30 so that the width is the same as the length of the slit 32 of the top surface member 30 by the clad plate material. Are formed in a rectangular shape as a whole. Therefore, when the top member 30 is assembled to the bottom member 50 and the wall member 50 is inserted into the slit 32, the insertion end of the wall member 60 is fitted into the positioning groove 52 of the bottom member 50, and the insertion end of the wall member 60 is The opposite end face is flush with the top face of the top face member 30. The wall member 60 has a plurality of through holes 62a to 62d.

なお、上述した頂面部材30や底面部材50,壁部材60の形成は、プレス機により折り曲げ加工や打ち抜き加工を施すことにより容易に行なうことができる。   In addition, formation of the top surface member 30, the bottom surface member 50, and the wall member 60 mentioned above can be easily performed by performing a bending process or a punching process with a press.

管部材70a,70bは、クラッド板材の中心材である第1金属(例えばアルミニウムやステンレス)により、その外径が底面部材50の側面に形成された2つの貫通孔54a,54bの直径と同一となるように形成された金属管を切断することにより形成されている。したがって、管部材70a,70bは、底面部材50の側面の2つの貫通孔54a,54bにそれぞれ嵌挿することができる。   The tube members 70a and 70b have the same outer diameter as the diameters of the two through holes 54a and 54b formed on the side surface of the bottom member 50 by the first metal (for example, aluminum or stainless steel) that is the central member of the clad plate material. It is formed by cutting a metal tube formed to be. Therefore, the pipe members 70a and 70b can be fitted into the two through holes 54a and 54b on the side surface of the bottom member 50, respectively.

箱状部材20の製造方法では、こうして頂面部材30や底面部材50,壁部材60,管部材70a,70bを形成すると、これらを組み付けて箱状部材とし(工程S110)、この状態の箱状部材をクラッド板材の第1金属の融点より低く第2金属の融点より高い温度に調整された炉に入れて第2金属をロウ材として用いてロウ付けを行ない(工程S120)、箱状部材20を完成する。   In the manufacturing method of the box-shaped member 20, when the top surface member 30, the bottom surface member 50, the wall member 60, and the pipe members 70a and 70b are thus formed, these are assembled to form a box-shaped member (step S110). The member is put into a furnace adjusted to a temperature lower than the melting point of the first metal and higher than the melting point of the second metal, and brazing is performed using the second metal as a brazing material (step S120), and the box-shaped member 20 To complete.

上述したように、底面部材50に頂面部材30を組み付けると、頂面部材30のコ字形状の端面38a,38bが底面部材50の側面の内側の縁部板面58a,58bに当接し、頂面部材30の両側面の端面38c,38dが底面部材50の底面の内側の縁部板面58c,58dに当接する。即ち、頂面部材30の全ての端面38a〜38dは底面部材50の板面58a〜58bに当接する。この状態で炉に入れられてロウ付けされるから、頂面部材30の全ての端面38a〜38dは底面部材50の板面58a〜58bに接合される。これにより、頂面部材30の端面38a〜38dは高い密閉性を得ることができる。   As described above, when the top surface member 30 is assembled to the bottom surface member 50, the U-shaped end surfaces 38a, 38b of the top surface member 30 come into contact with the inner side edge plate surfaces 58a, 58b of the side surface of the bottom surface member 50, The end surfaces 38 c and 38 d on both side surfaces of the top surface member 30 are in contact with the edge plate surfaces 58 c and 58 d inside the bottom surface of the bottom surface member 50. That is, all the end surfaces 38 a to 38 d of the top surface member 30 are in contact with the plate surfaces 58 a to 58 b of the bottom surface member 50. Since it is put into the furnace in this state and brazed, all the end surfaces 38 a to 38 d of the top member 30 are joined to the plate surfaces 58 a to 58 b of the bottom member 50. Thereby, the end surfaces 38a-38d of the top surface member 30 can obtain high sealing performance.

また、壁部材60の挿入端が底面部材50の位置決め溝52に嵌合し、壁部材60の挿入端とは反対の端面が頂面部材30の頂面と同一面となっている状態でロウ付けされるから、壁部材60の挿入端は底面部材50の位置決め溝52に接合され、壁部材60の挿入端とは反対の端部側面は頂面部材30のスリット32の開口端面に接合されることになる。壁部材60は幅がスリット32の長さと同一になるように形成されているから、壁部材60は隙間なくスリット32に接合される。この結果、スリット32において高い密閉性を得ることができる。   In addition, the insertion end of the wall member 60 is fitted into the positioning groove 52 of the bottom surface member 50, and the end surface opposite to the insertion end of the wall member 60 is flush with the top surface of the top surface member 30. Therefore, the insertion end of the wall member 60 is joined to the positioning groove 52 of the bottom surface member 50, and the end side surface opposite to the insertion end of the wall member 60 is joined to the opening end surface of the slit 32 of the top surface member 30. Will be. Since the wall member 60 is formed so that the width is the same as the length of the slit 32, the wall member 60 is joined to the slit 32 without a gap. As a result, high sealing performance can be obtained in the slit 32.

管部材70a,70bは底面部材50の側面の2つの貫通孔54a,54bにそれぞれ嵌挿された状態で炉に入れられる。したがって、底面部材50の2つの貫通孔54a,54bの近傍の第2金属の溶融により管部材70a,70bが2つの貫通孔54a,54bにそれぞれロウ付けされる。   The pipe members 70a and 70b are put into the furnace in a state of being fitted and inserted into the two through holes 54a and 54b on the side surface of the bottom member 50, respectively. Therefore, the pipe members 70a and 70b are brazed to the two through holes 54a and 54b, respectively, by melting the second metal in the vicinity of the two through holes 54a and 54b of the bottom member 50.

以上説明した第1実施例の箱状部材20の製造方法では、クラッド板材を用いて断面がコ字形状に頂面部材30を形成すると共に、クラッド板材を用いて頂面部材30の全ての端面が底面部材50の板面に当接するように断面がコ字形状に底面部材50を形成し、頂面部材30の全ての端面が底面部材50の板面に当接するように頂面部材30と底面部材50とを組み付け、この状態でクラッド板材の中心材としての第1金属の融点より低くクラッド板材の両面に接合されたロウ材としての第2金属より高い温度に調整された炉に入れてロウ付けを行なう。このため、接合部の密閉性の高い箱状部材20を製造することができる。頂面部材30や底面部材50の形成はプレス機により容易に行なうことができ、クラッド板材を用いているから炉に入れるだけで容易にロウ付けを行なうことができる。これらの結果、密閉性の高い箱状部材20を簡易に且つ迅速に製造することができる。   In the manufacturing method of the box-shaped member 20 of the first embodiment described above, the top surface member 30 is formed with a U-shaped cross section using a clad plate material, and all end surfaces of the top surface member 30 are formed using the clad plate material. The bottom member 50 is formed in a U-shaped cross section so that the bottom surface member 50 abuts the plate surface of the bottom surface member 50, and the top surface member 30 and the top surface member 30 are all in contact with the plate surface of the bottom surface member 50. The bottom member 50 is assembled, and in this state, it is placed in a furnace adjusted to a temperature lower than the melting point of the first metal as the center material of the clad plate material and higher than the second metal as the brazing material joined to both surfaces of the clad plate material. Perform brazing. For this reason, the box-shaped member 20 with high airtightness of a junction part can be manufactured. The top surface member 30 and the bottom surface member 50 can be easily formed by a press machine, and since a clad plate material is used, brazing can be easily performed only by placing it in a furnace. As a result, the box-shaped member 20 with high airtightness can be manufactured easily and quickly.

また、第1実施例の箱状部材20の製造方法では、頂面部材30の頂面にスリット32を形成し、底面部材50の底面に位置決め溝52を形成し、壁部材60をスリット32に挿入してその挿入端が位置決め溝52に嵌合した状態で炉に入れてロウ付けを行なう。このため、箱状部材20の内側に頂面部材30の頂面と底面部材50の底面とに接合した壁を容易に形成することができる。この壁が形成されることにより、製造された箱状部材20に内圧を作用させたときに生じ得る頂面部材30の頂面や底面部材50の底面が膨らむなどの変形を抑制することができる。   In the method for manufacturing the box-shaped member 20 of the first embodiment, the slit 32 is formed on the top surface of the top surface member 30, the positioning groove 52 is formed on the bottom surface of the bottom surface member 50, and the wall member 60 is formed into the slit 32. It inserts and puts in a furnace in the state which the insertion end fitted in the positioning groove | channel 52, and brazes. For this reason, the wall joined to the top face of the top face member 30 and the bottom face of the bottom face member 50 can be easily formed inside the box-shaped member 20. By forming this wall, it is possible to suppress deformation such as swelling of the top surface of the top surface member 30 and the bottom surface of the bottom surface member 50 that may occur when an internal pressure is applied to the manufactured box-shaped member 20. .

さらに、第1実施例の箱状部材20の製造方法では、底面部材50の側面に2つの貫通孔54a,54bを形成すると共に管部材70a,70bを形成し、この2つの貫通孔54a,54bに管部材70a,70bをそれぞれ嵌挿させた状態で炉に入れてロウ付けを行なう。このため、管部材70a,70bを2つの貫通孔54a,54bに容易に接合することができる。   Furthermore, in the manufacturing method of the box-shaped member 20 of the first embodiment, the two through holes 54a and 54b are formed on the side surface of the bottom surface member 50 and the tube members 70a and 70b are formed, and the two through holes 54a and 54b are formed. Then, the tube members 70a and 70b are fitted and inserted into the furnace and brazed. For this reason, the pipe members 70a and 70b can be easily joined to the two through holes 54a and 54b.

第1実施例の箱状部材20の製造方法では、上述した頂面部材30と底面部材50とのロウ付けや、壁部材60のロウ付け、管部材70a,70bのロウ付けは、これらを組み付けて1回のみ炉に入れることにより同時に行なわれる。このため、個別にロウ付けを行なうものや溶接により取り付けるものに比して、作業工程を少なくすることができ、迅速に且つ簡易に接合することができる。   In the manufacturing method of the box-shaped member 20 of the first embodiment, the above-described brazing of the top member 30 and the bottom member 50, brazing of the wall member 60, and brazing of the pipe members 70a and 70b are assembled. At the same time by placing it in the furnace only once. For this reason, compared with what brazes separately and what is attached by welding, a work process can be decreased and it can join rapidly and simply.

また、第1実施例の箱状部材20の製造方法では、底面部材50の側面に浅い溝56a,56bを形成する。このため、製造された箱状部材20の側面の剛性を高くすることができ、箱状部材20に内圧を作用させたときに生じ得る側面の変形を抑制することができる。   In the method for manufacturing the box-shaped member 20 according to the first embodiment, the shallow grooves 56 a and 56 b are formed on the side surface of the bottom surface member 50. For this reason, the rigidity of the side surface of the manufactured box-shaped member 20 can be increased, and deformation of the side surface that can occur when an internal pressure is applied to the box-shaped member 20 can be suppressed.

第1実施例の箱状部材20の製造方法では、クラッド板材を用いて断面がコ字形状に頂面部材30を形成すると共に、クラッド板材を用いて頂面部材30の全ての端面が底面部材50の板面に当接するように断面がコ字形状に底面部材50を形成するものとした。しかし、頂面部材と底面部材とが接合されればよいから、底面部材の全ての端面が頂面部材の板面に当接するようにコ字形状に頂面部材と底面部材とを形成するものとしてもよい。即ち、頂面部材と底面部材は、一方の部材の端面が他方の部材の板面に当接するように形成されていればよい。   In the manufacturing method of the box-shaped member 20 of the first embodiment, the top surface member 30 is formed with a U-shaped cross section using a clad plate material, and all end surfaces of the top surface member 30 are bottom surface members using the clad plate material. The bottom member 50 is formed to have a U-shaped cross section so as to come into contact with 50 plate surfaces. However, since the top member and the bottom member only need to be joined, the top member and the bottom member are formed in a U shape so that all end faces of the bottom member abut against the plate surface of the top member. It is good. That is, the top surface member and the bottom surface member may be formed so that the end surface of one member is in contact with the plate surface of the other member.

第1実施例の箱状部材20の製造方法では、頂面部材30の頂面にスリット32を形成すると共に底面部材50の底面に位置決め溝52を形成し、壁部材60をスリット32に挿入して、箱状部材20の内部に壁を形成するものとした。しかし、壁は一枚に限定されず、箱状部材の内部に複数の壁を形成するものとしてもよい。この場合、頂面部材の頂面に複数のスリットを形成すると共に底面部材の底面に複数の位置決め溝を形成し、複数のスリットの全てに複数の壁部材を挿入すればよい。また、底面部材50の底面の位置決め溝52に代えて底面にスリットを形成するものとしてもよい。この場合、壁部材が頂面部材の頂面のスリットと底面部材の底面のスリットに嵌挿している状態でロウ付けすればよい。また、クラッド板材の厚みに比して箱状部材が小さく十分な強度を有する場合や箱状部材の内圧が小さい場合には、箱状部材の内部に壁を形成しないものとしてもよい。この場合、頂面部材の頂面のスリットや底面部材の底面の位置決め溝は形成する必要がない。   In the manufacturing method of the box-shaped member 20 of the first embodiment, the slit 32 is formed on the top surface of the top surface member 30, the positioning groove 52 is formed on the bottom surface of the bottom surface member 50, and the wall member 60 is inserted into the slit 32. Thus, a wall is formed inside the box-shaped member 20. However, the number of walls is not limited to one, and a plurality of walls may be formed inside the box-shaped member. In this case, a plurality of slits may be formed on the top surface of the top surface member, a plurality of positioning grooves may be formed on the bottom surface of the bottom surface member, and a plurality of wall members may be inserted into all of the plurality of slits. Moreover, it is good also as what replaces with the positioning groove | channel 52 of the bottom face of the bottom face member 50, and forms a slit in a bottom face. In this case, the wall member may be brazed in a state where the wall member is fitted into the slit on the top surface of the top surface member and the slit on the bottom surface of the bottom surface member. Further, when the box-shaped member is small compared to the thickness of the clad plate material and has sufficient strength, or when the internal pressure of the box-shaped member is small, no wall may be formed inside the box-shaped member. In this case, it is not necessary to form a slit on the top surface of the top surface member or a positioning groove on the bottom surface of the bottom surface member.

第1実施例の箱状部材20の製造方法では、壁部材60の長さを箱状部材20を完全に区切らない長さとすると共に壁部材60に複数の貫通孔62a〜62dを形成して、箱状部材20の内部で流体が流通するようにした。しかし、壁部材に貫通孔を形成しないものとしてもよいし、壁部材により箱状部材の内部を完全に2つに区切るものとしても構わない。   In the manufacturing method of the box-shaped member 20 of the first embodiment, the length of the wall member 60 is set to a length that does not completely divide the box-shaped member 20, and a plurality of through holes 62a to 62d are formed in the wall member 60.

第1実施例の箱状部材20の製造方法では、底面部材50の側面に内側に凸の浅い溝56a,56bを形成するものとした。しかし、側面の剛性を高めるものであればよいから、外側に凸の溝としたり、リブを形成するものとしたりしてもよい。また、溝やリブを形成する位置は、底面部材の側面に限られるものではなく、底面部材の底面や頂面部材の頂面、頂面部材の側面などに形成してもよい。また、こうした溝やリブを形成しないものとしてもよい。   In the manufacturing method of the box-shaped member 20 according to the first embodiment, the shallow grooves 56 a and 56 b that are convex on the inner side are formed on the side surface of the bottom surface member 50. However, since it may be anything that increases the rigidity of the side surface, it may be formed as an outwardly convex groove or a rib. Further, the positions where the grooves and ribs are formed are not limited to the side surface of the bottom surface member, but may be formed on the bottom surface of the bottom surface member, the top surface of the top surface member, the side surface of the top surface member, or the like. Moreover, it is good also as what does not form such a groove | channel and a rib.

However, the cross-section of the portion forming the box may be U-shaped. As shown in the top surface member 30B of the modification of FIG. 4, fin portions 39B may be formed on both side surfaces. In this case, the U-shaped end surface of the portion forming the box in the end surface of the top surface member 30B abuts the plate surface of the bottom surface member 50, and the other end surface (the end surface of the fin portion 39B) is the plate of the bottom surface member 50. It does not touch the surface. Further, the side surface of the top surface member 30 </ b> B and the bottom surface of the bent portion of the fin portion 39 </ b> B are in contact with the bottom surface of the bottom surface member 50.

Form (step S200). The clad plate material has been described in the first embodiment.

第1頂面部材130は、クラッド板材により、全体として断面がコ字形状に形成されており、その側面の一方(図5中右面)には複数の貫通孔136a,136bが形成されている。   The first top member 130 has a U-shaped cross section as a whole by a clad plate material, and a plurality of through holes 136a and 136b are formed on one of the side surfaces (the right surface in FIG. 5).

第2頂面部材140は、クラッド板材により、側面の高さH2が第1頂面部材130の側面の高さH1と同一になるように、長さL2が第1頂面部材130の長さL1と同一になるように、全体として断面がコ字形状に形成されている。第2頂面部材140の側面の一方(図5中左面)には、第1頂面部材130の側面に形成された複数の貫通孔136a,136bと整合するように、複数の貫通孔146a,146bが形成されている。したがって、水平面に開口部が下を向くように且つ第1頂面部材130の側面と第2頂面部材140の側面とが接するように並べると、2つの頂面が同一高さで連続するようになり、両部材の側面に形成された複数の貫通孔136a,136bと複数の貫通孔146a,146bとが連通する。   The length L2 of the second top surface member 140 is the length of the first top surface member 130 such that the height H2 of the side surface is the same as the height H1 of the side surface of the first top surface member 130 by the clad plate material. The entire cross section is formed in a U shape so as to be the same as L1. One of the side surfaces of the second top surface member 140 (left surface in FIG. 5) has a plurality of through holes 146a, 146a, 136a, 136b aligned with the plurality of through holes 136a, 136b formed on the side surface of the first top surface member 130. 146b is formed. Accordingly, when the side surfaces of the first top surface member 130 and the side surfaces of the second top surface member 140 are in contact with each other so that the opening faces downward in the horizontal plane, the two top surfaces are continuous at the same height. Thus, the plurality of through holes 136a and 136b formed on the side surfaces of both members communicate with the plurality of through holes 146a and 146b.

底面部材150は、クラッド板材により、長さが第1頂面部材130の頂面の幅と第2頂面部材140の頂面の幅との和の長さになるように、底面の幅が第1頂面部材130や第2頂面部材140の長さにクラッド板材2枚分の厚みを加えた長さになるように、側面の高さが第1頂面部材130の側面や第2頂面部材140の側面の高さにクラッド板材1枚分の厚みを加えた長さになるように、全体として断面がコ字形状に形成されている。したがって、底面部材150に第1頂面部材130と第2頂面部材140とを開口部が対向するように且つ第1頂面部材130の貫通孔136a,136bが形成された側面と第2頂面部材140の貫通孔146a,146bが形成された側面とが接するように組み付けると、第1頂面部材130のコ字形状の端面138a,138bが底面部材150の側面に当接すると共に第1頂面部材130の両側面の端面138c,138dが底面部材150の底面に当接し、第2頂面部材140のコ字形状の端面148a,148bが底面部材150の側面に当接すると共に第2頂面部材140の両側面の端面148c,148dが底面部材150の底面に当接する。また、底面部材50の一方の側面(図5中右手前の側面)には、2つの貫通孔154a,154bが形成されている。この2つの貫通孔154a,154bは、箱状部材120の内側への流体の流入口や流出口となる。   The width of the bottom surface of the bottom member 150 is made of a clad plate material so that the length becomes the sum of the width of the top surface of the first top surface member 130 and the width of the top surface of the second top surface member 140. The height of the side surface is equal to the length of the side surface of the first top surface member 130 or the second side so that the length of the first top surface member 130 or the second top surface member 140 is added to the thickness of two clad plates. The cross section is formed in a U shape as a whole so as to have a length obtained by adding the thickness of one side of the clad plate to the height of the side surface of the top surface member 140. Accordingly, the first top surface member 130 and the second top surface member 140 are opposed to the bottom surface member 150 such that the openings face each other and the side surfaces where the through holes 136a and 136b of the first top surface member 130 are formed and the second top surface. When assembled so that the side surfaces of the surface member 140 where the through holes 146a and 146b are formed are in contact with each other, the U-shaped end surfaces 138a and 138b of the first top surface member 130 abut on the side surfaces of the bottom surface member 150 and the first top End surfaces 138c and 138d on both side surfaces of the surface member 130 are in contact with the bottom surface of the bottom surface member 150, and U-shaped end surfaces 148a and 148b of the second top surface member 140 are in contact with the side surfaces of the bottom surface member 150 and the second top surface. End surfaces 148 c and 148 d on both side surfaces of the member 140 are in contact with the bottom surface of the bottom surface member 150. Further, two through holes 154a and 154b are formed on one side surface of the bottom member 50 (the side surface on the right front side in FIG. 5). The two through holes 154 a and 154 b serve as an inflow port and an outflow port for fluid to the inside of the box-shaped member 120.

なお、上述した第1頂面部材130や第2頂面部材140,底面部材50の形成は、プレス機により折り曲げ加工や打ち抜き加工を施すことにより容易に行なうことができる。   The first top surface member 130, the second top surface member 140, and the bottom surface member 50 described above can be easily formed by bending or punching with a press.

管部材170a,170bは、クラッド板材の中心材である第1金属(例えばアルミニウムやステンレス)により、その外径が底面部材150の側面に形成された2つの貫通孔154a,154bの直径と同一となるように形成された金属管を切断することにより形成されている。したがって、管部材170a,170bは、底面部材150の側面の2つの貫通孔154a,154bにそれぞれ嵌挿することができる。   The pipe members 170a and 170b have the same outer diameter as the diameters of the two through holes 154a and 154b formed on the side surface of the bottom member 150 by the first metal (for example, aluminum or stainless steel) that is the central member of the clad plate material. It is formed by cutting a metal tube formed to be. Therefore, the pipe members 170a and 170b can be fitted into the two through holes 154a and 154b on the side surface of the bottom member 150, respectively.

第2実施例の箱状部材120の製造方法では、こうして第1頂面部材130や第2頂面部材140,底面部材150,管部材170a,170bを形成すると、これらを組み付けて箱状部材とし(工程S210)、この状態の箱状部材をクラッド板材の第1金属の融点より低く第2金属の融点より高い温度に調整された炉に入れて第2金属をロウ材として用いてロウ付けを行ない(工程S220)、箱状部材120を完成する。   In the manufacturing method of the box-shaped member 120 of the second embodiment, when the first top surface member 130, the second top surface member 140, the bottom surface member 150, and the pipe members 170a and 170b are thus formed, these are assembled into a box-shaped member. (Step S210), the box-shaped member in this state is placed in a furnace adjusted to a temperature lower than the melting point of the first metal of the clad plate material and higher than the melting point of the second metal, and brazing is performed using the second metal as a brazing material. Performing (step S220), the box-shaped member 120 is completed.

上述したように、底面部材150に第1頂面部材130と第2頂面部材140とを組み付けると、第1頂面部材130の全ての端面138a〜138dは底面部材150の側面や底面に当接し、第2頂面部材140の全ての端面148a〜148dは底面部材150の側面や底面に当接する。この状態で炉に入れられてロウ付けされるから、第1頂面部材130の全ての端面138a〜138dおよび第2頂面部材140の全ての端面148a〜148dは底面部材150の側面や底面に接合される。これにより、第1頂面部材130の端面138a〜138dや第2頂面部材140の端面148a〜148dは高い密閉性を得ることができる。   As described above, when the first top surface member 130 and the second top surface member 140 are assembled to the bottom surface member 150, all the end surfaces 138a to 138d of the first top surface member 130 are in contact with the side surface and bottom surface of the bottom surface member 150. All the end surfaces 148 a to 148 d of the second top surface member 140 are in contact with the side surface and the bottom surface of the bottom surface member 150. Since it is put into the furnace in this state and brazed, all the end surfaces 138 a to 138 d of the first top surface member 130 and all the end surfaces 148 a to 148 d of the second top surface member 140 are placed on the side surface and the bottom surface of the bottom surface member 150. Be joined. Thereby, the end surfaces 138a to 138d of the first top surface member 130 and the end surfaces 148a to 148d of the second top surface member 140 can obtain high sealing performance.

また、管部材170a,170bは底面部材150の側面の2つの貫通孔154a,154bにそれぞれ嵌挿された状態で炉に入れられる。したがって、底面部材150の2つの貫通孔154a,154bの近傍の第2金属の溶融により管部材170a,170bが2つの貫通孔154a,154bにそれぞれロウ付けされる。   Further, the pipe members 170a and 170b are put into the furnace in a state where they are fitted and inserted into the two through holes 154a and 154b on the side surface of the bottom member 150, respectively. Therefore, the pipe members 170a and 170b are brazed to the two through holes 154a and 154b, respectively, by melting of the second metal in the vicinity of the two through holes 154a and 154b of the bottom member 150.

以上説明した第2実施例の箱状部材120の製造方法では、クラッド板材を用いて断面がコ字形状に第1頂面部材130を形成すると共に、クラッド板材を用いて側面の高さH2が第1頂面部材130の側面の高さH1と同一になるように長さL2が第1頂面部材130の長さL1と同一になるように断面がコ字形状に第2頂面部材140を形成し、クラッド板材を用いて第1頂面部材130および第2頂面部材140の全ての端面が底面部材150の板面に当接するように断面がコ字形状に底面部材150を形成し、第1頂面部材130および第2頂面部材140の全ての端面が底面部材150の板面に当接するように第1頂面部材130と第2頂面部材140とを底面部材150に組み付け、この状態でクラッド板材の中心材としての第1金属の融点より低くクラッド板材の両面に接合されたロウ材としての第2金属より高い温度に調整された炉に入れてロウ付けを行なう。このため、接合部の密閉性の高い箱状部材120を製造することができる。第1頂面部材130や第2頂面部材140,底面部材150の形成はプレス機により容易に行なうことができ、クラッド板材を用いているから炉に入れるだけで容易にロウ付けを行なうことができる。これらの結果、密閉性の高い箱状部材120を簡易に且つ迅速に製造することができる。   In the manufacturing method of the box-shaped member 120 of the second embodiment described above, the first top surface member 130 is formed with a U-shaped cross section using a clad plate material, and the side height H2 is made using the clad plate material. The second top surface member 140 has a U-shaped cross section so that the length L2 is the same as the length L1 of the first top surface member 130 so as to be the same as the height H1 of the side surface of the first top surface member 130. And forming the bottom member 150 with a U-shaped cross section so that all the end surfaces of the first top member 130 and the second top member 140 are in contact with the plate surface of the bottom member 150 using the clad plate material. The first top surface member 130 and the second top surface member 140 are assembled to the bottom surface member 150 so that all end surfaces of the first top surface member 130 and the second top surface member 140 are in contact with the plate surface of the bottom surface member 150. In this state, as the center material of the clad plate material Performing brazing a furnace is adjusted to a temperature higher than the second metal as the brazing material bonded to both sides of the lower clad plate than the melting point of the metal. For this reason, the box-shaped member 120 with high sealing property of a junction part can be manufactured. The first top surface member 130, the second top surface member 140, and the bottom surface member 150 can be easily formed by a press machine. Since a clad plate material is used, brazing can be easily performed only by placing in a furnace. it can. As a result, the box-shaped member 120 with high airtightness can be manufactured easily and quickly.

また、第2実施例の箱状部材120の製造方法では、第1頂面部材130と第2頂面部材140とを並べて底面部材150に組み付けてロウ付けするから、箱状部材120の内部に箱状部材120の頂面と底面とに接合すると共に底面部材の両側面に接合する壁が形成される。このため、箱状部材120に内圧を作用させたときに生じ得る箱状部材120の頂面や底面,側面が膨らむなどの変形を抑制することができる。   Further, in the method for manufacturing the box-shaped member 120 of the second embodiment, the first top surface member 130 and the second top surface member 140 are arranged side by side and assembled to the bottom surface member 150 and brazed. Walls are formed that are bonded to the top surface and the bottom surface of the box-shaped member 120 and are bonded to both side surfaces of the bottom surface member. For this reason, it is possible to suppress deformation such as swelling of the top surface, bottom surface, and side surfaces of the box-shaped member 120 that may occur when an internal pressure is applied to the box-shaped member 120.

さらに、第2実施例の箱状部材120の製造方法では、底面部材150の側面に2つの貫通孔154a,154bを形成すると共に管部材170a,170bを形成し、この2つの貫通孔154a,154bに管部材170a,170bをそれぞれ嵌挿させた状態で炉に入れてロウ付けを行なう。このため、管部材170a,170bを2つの貫通孔154a,154bに容易に接合することができる。   Furthermore, in the manufacturing method of the box-shaped member 120 of the second embodiment, two through holes 154a and 154b are formed on the side surface of the bottom member 150, and tube members 170a and 170b are formed, and the two through holes 154a and 154b are formed. Then, the tube members 170a and 170b are fitted and inserted into the furnace and brazed. For this reason, the pipe members 170a and 170b can be easily joined to the two through holes 154a and 154b.

第2実施例の箱状部材120の製造方法では、上述した第1頂面部材130や第2頂面部材140と底面部材150とのロウ付けや、管部材170a,170bのロウ付けは、これらを組み付けて1回のみ炉に入れることにより同時に行なわれる。このため、個別にロウ付けを行なうものや溶接により取り付けるものに比して、作業工程を少なくすることができ、迅速に且つ簡易に接合することができる。   In the manufacturing method of the box-shaped member 120 of the second embodiment, the brazing of the first top surface member 130 or the second top surface member 140 and the bottom surface member 150 and the brazing of the tube members 170a and 170b described above are performed. It is performed at the same time by assembling and putting it into the furnace only once. For this reason, compared with what brazes separately and what is attached by welding, a work process can be decreased and it can join rapidly and simply.

第2実施例の箱状部材120の製造方法では、クラッド板材を用いて断面がコ字形状に第1頂面部材130を形成すると共に、クラッド板材を用いて側面の高さH2が第1頂面部材130の側面の高さH1と同一になるように長さL2が第1頂面部材130の長さL1と同一になるように断面がコ字形状に第2頂面部材130を形成し、クラッド板材を用いて第1頂面部材130および第2頂面部材140の全ての端面が底面部材150の板面に当接するように断面がコ字形状に底面部材150を形成するものとした。しかし、頂面部材は、側面の高さが同一で長さが同一となるように断面をコ字形状に形成すればよいから、3つ以上の頂面部材を形成し、3つ以上の頂面部材を整列させたときに全ての頂面部材の全ての端面が底面部材の板面に当接するように底面部材を形成するものとしてもよい。こうすれば、3つ以上の頂面部材を用いた箱状部材を容易に製造することができる。   In the manufacturing method of the box-shaped member 120 of the second embodiment, the first top surface member 130 is formed with a U-shaped cross section using a clad plate material, and the side height H2 is set to the first top using the clad plate material. The second top surface member 130 is formed with a U-shaped cross section so that the length L2 is the same as the length L1 of the first top surface member 130 so as to be the same as the height H1 of the side surface of the surface member 130. The bottom member 150 is formed with a U-shaped cross section so that all end surfaces of the first top member 130 and the second top member 140 are in contact with the plate surface of the bottom member 150 using the clad plate material. . However, since the top surface member has only to be formed in a U-shaped cross section so that the height of the side surface is the same and the length is the same, three or more top surface members are formed, and three or more top members are formed. The bottom member may be formed so that all end surfaces of all top members contact the plate surface of the bottom member when the surface members are aligned. If it carries out like this, the box-shaped member using three or more top surface members can be manufactured easily.

第2実施例の箱状部材120の製造方法では、第1頂面部材130の側面に複数の貫通孔136a,136bを形成すると共に第2頂面部材140の側面に複数の貫通孔148a,148bを形成し、箱状部材120の内部で流体が流通するようにした。しかし、第1頂面部材の側面や第2頂面部材の側面に貫通孔を形成しないものとしてもよい。こうすれば、箱状部材の内側を2つに区切ることができる。なお、3つ以上の頂面部材を用いれば、箱状部材の内側を3つ以上に区切ることができる。   In the method of manufacturing the box-shaped member 120 according to the second embodiment, a plurality of through holes 136 a and 136 b are formed on the side surface of the first top surface member 130 and a plurality of through holes 148 a and 148 b are formed on the side surface of the second top surface member 140. The fluid is circulated inside the box-shaped member 120. However, the through hole may not be formed on the side surface of the first top surface member or the side surface of the second top surface member. If it carries out like this, the inner side of a box-shaped member can be divided into two. If three or more top surface members are used, the inside of the box-shaped member can be divided into three or more.

第2実施例の箱状部材120の製造方法では、底面部材150の側面に2つの貫通孔154a,154bを形成すると共に管部材170a,170bを形成し、この貫通孔154a,154bに管部材170a,170bをロウ付けするものとした。しかし、流入口や流出口の形成は2つに限定されるものではなく3つ以上形成するものとしてもよい。また、流入口や流出口の形状は円形状に限定されるものではなく、楕円形状としたり矩形形状としたりしてもよい。また、流入口や流出口に管部材をロウ付けしないものとしても構わない。   In the manufacturing method of the box-shaped member 120 of the second embodiment, two through holes 154a and 154b are formed on the side surface of the bottom member 150, and the tube members 170a and 170b are formed. The tube member 170a is formed in the through holes 154a and 154b. , 170b is brazed. However, the formation of the inlet and the outlet is not limited to two, and three or more may be formed. Moreover, the shape of an inflow port or an outflow port is not limited to circular shape, You may make it elliptical shape or a rectangular shape. Further, the pipe member may not be brazed to the inflow port or the outflow port.
