Description
【0001】[0001]
本考案は、ブレージングシートなどの被ろう付け部材をろう付けする際、その 被ろう付け部材を加圧拘束するろう付け治具に関する。 The present invention relates to a brazing jig for pressurizing and restraining a brazed member such as a brazing sheet when brazing the brazed member.
【0002】[0002]
従来より、例えば熱交換器,金属ベローズ,ろう付けハニカムなどのように通 常の溶接による製造が困難な金属製品では、ろう付けによる製造が一般的に行わ れている。そして、この種の製品のろう付けには次のようなろう付け治具が用い られる。例えば、互いに近接離隔可能な上下一対の加圧板と、上側の加圧板と被 ろう付け部材との間に配設されたコイルバネと、下側加圧板の四隅に立設され上 側加圧板を貫通してナットと螺合するボルトと、を備えたろう付け治具がそれで ある。 Conventionally, brazing is generally used for metal products such as heat exchangers, metal bellows, and brazed honeycombs that are difficult to manufacture by ordinary welding. The following brazing jigs are used for brazing this type of product. For example, a pair of upper and lower pressure plates that can be moved closer to and away from each other, a coil spring disposed between the upper pressure plate and the brazed member, and a lower pressure plate that is erected upright at the four corners and penetrates the upper pressure plate. It is a brazing jig with a bolt that is screwed onto the nut.
【0003】 このように構成されたろう付け治具では、下側加圧板上に例えばブレージング シートなどを積層することによって被ろう付け部材を形成し、その上にコイルバ ネおよび上側加圧板を順次載置する。続いてナットを締め付けて上下一対の加圧 板の離隔距離を規定することによって被ろう付け部材を加圧拘束することができ る。そして、その被ろう付け部材をろう付け治具で加圧拘束しながら加熱すると 、ブレージングシートのろう合金が融解し、ブレージングシートを接合すること ができる。In the brazing jig thus configured, a brazing member is formed by laminating, for example, a brazing sheet on the lower pressure plate, and the coil panel and the upper pressure plate are sequentially placed on the brazed member. To do. Then, by tightening the nut to regulate the separation distance between the upper and lower pressure plates, the brazed member can be pressed and restrained. When the brazed member is heated while being pressed and restrained by a brazing jig, the brazing alloy of the brazing sheet is melted and the brazing sheet can be joined.

この種のろう付け治具では、例えばある種のハニカムなどのように、大型でか つ表面に凹凸のある被ろう付け部材を加圧拘束する場合、次のような部品を使用 する必要があった。 In this type of brazing jig, the following parts need to be used when pressurizing and restraining a brazed member that is large and has an uneven surface, such as a type of honeycomb. It was
【0005】 即ち、ろう付け部材が大型であると一本のコイルバネだけでは均一な加圧が行 えない。このため、被ろう付け部材の端面に自然長およびバネ定数の等しい多数 のコイルバネを並設して、その上から上側加圧板を載置する必要があった。また 、被ろう付け部材に凹凸があると被ろう付け部材の窪み込んだところにもコイル バネを配設しなければならない。一方各コイルバネは、前述したように自然長お よびバネ定数が等しい。このため、窪み込んだところに配設されたコイルバネの 弾発力を他の部分に配設されたコイルバネのそれと一致させるためには、該コイ ルバネ先端に窪みの深さ大きさに応じたスペーサを配設する必要があった。That is, if the brazing member is large, uniform pressing cannot be performed with only one coil spring. For this reason, it is necessary to arrange a number of coil springs having the same natural length and the same spring constant in parallel on the end surface of the brazed member, and to mount the upper pressure plate from above. Further, if the brazed member has irregularities, the coil spring must be arranged in the recessed part of the brazed member. On the other hand, each coil spring has the same natural length and spring constant as described above. Therefore, in order to make the resilience of the coil spring arranged in the recessed part equal to that of the coil spring arranged in the other part, a spacer corresponding to the depth of the recess is formed at the tip of the coil spring. Had to be installed.
【0006】 これらの場合、ろう付け部材を加圧拘束するために非常に多くの部品が必要と なる。従って、被ろう付け部材をろう付け治具に組み付ける作業が繁雑になり、 ろう付け作業全体の能率向上にとって大きな障害となっていた。 そこで本考案は、被ろう付け部材の組み付け作業を能率的に行うことのできる ろう付け治具を提供することを目的としてなされた。In these cases, a large number of parts are required to press-fit the brazing member. Therefore, the work of assembling the brazed member to the brazing jig becomes complicated, which is a major obstacle to improving the efficiency of the whole brazing work. Then, this invention was made for the purpose of providing the brazing jig which can perform the assembling work of a brazed member efficiently.

上記目的を達するためになされた請求項1記載の考案(以下第1考案と記載) は、 互いに近接離隔可能な一対の加圧板と、 少なくともいずれか一方の上記加圧板と、上記一対の加圧板の間に配置された 被ろう付け部材との間に配設された弾発部材と、 上記一対の加圧板の離隔距離を規定することにより、上記被ろう付け部材を上 記弾発部材を介して加圧拘束する拘束部材と、 を備えたろう付け治具において、 上記弾発部材が、少なくとも上記被ろう付け部材周縁部を加圧する大径のコイ ルバネと、該コイルバネの内側に配設された小径のコイルバネとを有して構成さ れることを特徴とするろう付け治具を要旨としており、 一方請求項2記載の考案(以下第2考案と記載)は、 互いに近接離隔可能な一対の加圧板と、 少なくともいずれか一方の上記加圧板と、上記一対の加圧板の間に配置された 被ろう付け部材との間に配設された弾発部材と、 上記一対の加圧板の離隔距離を規定することにより、上記被ろう付け部材を上 記弾発部材を介して加圧拘束する拘束部材と、 を備えたろう付け治具において、 上記弾発部材が複数の部材から構成され、かつ上記加圧板と上記各弾発部材が 配設される上記被ろう付け部材端面との間隔に応じて上記各弾発部材の弾性定数 または自然長を異ならせることにより、上記各弾発部材が上記被ろう付け部材端 面に加える圧力を同一にしてなることを特徴とするろう付け治具を要旨としてい る。 The invention (1st invention) of Claim 1 made in order to achieve the said object is a pair of pressurization plates which can mutually approach and separate, The said pressure plate of at least any one, The said pair of pressurization. By defining the separation distance between the elastic member arranged between the brazing member arranged between the plates and the pair of pressure plates, the brazing member can be separated by the elastic member. A brazing jig including: a restraining member for pressurizing and restraining, wherein the elastic member is a large-diameter coil spring that pressurizes at least the peripheral portion of the brazed member, and a small-diameter coil spring disposed inside the coil spring. The invention is based on a brazing jig, which is characterized in that it has a coil spring and a coil spring, and the invention according to claim 2 (hereinafter referred to as the second invention) is a pair of pressure plates which can be separated from each other. And at least one By defining the separation distance between the elastic member disposed between one of the pressure plates and the brazed member disposed between the pair of pressure plates, and the separation distance between the pair of pressure plates, A brazing jig comprising: a restraining member that pressurizes and restrains the brazed member via the elastic member, wherein the elastic member includes a plurality of members, and the pressure plate and the elastic members Each elastic member is added to the end surface of the brazed member by changing the elastic constant or natural length of each elastic member according to the distance from the end surface of the brazed member on which the member is disposed. The gist is a brazing jig, which is characterized in that the pressure is the same.
【0008】[0008]
以上のように構成された第1考案では、弾発部材が少なくとも、被ろう付け部 材周縁部を加圧する大径のコイルバネと、該コイルバネの内側に配設された小径 のコイルバネとを有して構成されている。 In the first aspect of the invention configured as described above, the elastic member includes at least a large-diameter coil spring that pressurizes the peripheral portion of the brazed part and a small-diameter coil spring that is disposed inside the coil spring. Is configured.
【0009】 このため被ろう付け部材が大型である場合も、大径のコイルバネが一本で被ろ う付け部材周縁部全体を均一に加圧する。また、被ろう付け部材が大型である場 合大径のコイルバネの内側に圧力が充分に加わらない部分が生じることがある。 大径のコイルバネの内側に配設された小径のコイルバネは、この部分の被ろう付 け部材を加圧する。Therefore, even when the brazing member is large, one large-diameter coil spring uniformly presses the entire periphery of the brazing member. In addition, when the brazed member is large, there may be a portion where the pressure is not sufficiently applied inside the large diameter coil spring. The small-diameter coil spring arranged inside the large-diameter coil spring pressurizes the brazed member in this portion.
【0010】 一方第2考案では、弾発部材を複数の部材から構成し、かつ加圧板と各弾発部 材が配設される被ろう付け部材端面との間隔に応じて各弾発部材の弾性定数また は自然長を異ならせている。そして、これによって各弾発部材が被ろう付け部材 端面に加える圧力を同一にしている。On the other hand, in the second invention, the elastic member is composed of a plurality of members, and the elastic member of each elastic member is adjusted according to the distance between the pressure plate and the end surface of the brazed member on which the elastic member is disposed. Different elastic constants or natural lengths. As a result, the pressure applied by each elastic member to the end surface of the brazed member is the same.
【0011】 弾発部材をこのように構成することによって、被ろう付け部材に凹凸があり、 被ろう付け部材端面の窪み込んだところなどに弾発部材を配設しなければならな い場合であってもスペーサを使用する必要はない。即ち、各弾発部材を所定の場 所に配設して一対の加圧板の離隔距離を規定すれば、各弾発部材は被ろう付け部 材端面に同一の圧力を加えるのである。By configuring the elastic member in this way, in the case where the brazed member has irregularities and the elastic member has to be arranged in a recessed portion of the end surface of the brazed member, etc. There is no need to use spacers, if any. That is, if each elastic member is arranged at a predetermined place and the separation distance between the pair of pressure plates is regulated, each elastic member applies the same pressure to the end surface of the brazed part.

次に、本考案の実施例を図面と共に説明する。図2は熱交換器51のろう付け 工程で用いられる実施例のろう付け治具1の平面図であり、図1はそのA−A線 断面図である。但し、図2は後述する上側加圧板3を省略して描いている。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a plan view of the brazing jig 1 of the embodiment used in the brazing process of the heat exchanger 51, and FIG. 1 is a sectional view taken along the line AA. However, in FIG. 2, the upper pressure plate 3 described later is omitted.
【0013】 先ず、図1に示すように熱交換器51は、環状の窪み53aが形成されたブレ ージングシート製の円板53を、窪み53aが互いに対向するように交互に向き を替えて台座55上に積層することによって形成されている。互いに対向して積 層された窪み53aの内側には冷媒が流動する環状の冷媒流路57が形成される 。また、窪み53aを互いに背中合わせにした円板53の間で冷媒流路57の円 環の内側に形成される間隙には、アルミニウム合金製のコルゲートフィン59が 配設されている。また、台座55と最下部の円板53との間隙にもアルミニウム 合金製のコルゲートフィン61が配設されている。なお、各部材53〜61が互 いに接触する部分Zは後述の処理によってろう付けされる部分である。First, as shown in FIG. 1, in the heat exchanger 51, a disc 53 made of a blazing sheet in which an annular recess 53 a is formed is alternately turned so that the recesses 53 a face each other. It is formed by stacking on top. An annular coolant channel 57 through which the coolant flows is formed inside the recesses 53a that are stacked facing each other. Further, aluminum alloy corrugated fins 59 are arranged in a gap formed inside the ring of the coolant channel 57 between the discs 53 in which the recesses 53a are placed back to back. Further, a corrugated fin 61 made of aluminum alloy is also disposed in the gap between the base 55 and the lowermost disc 53. A portion Z where the members 53 to 61 contact each other is a portion to be brazed by the process described later.
【0014】 ろう付け治具1は、正方形の上側加圧板3および下側加圧板5と、下側加圧板 5の四隅から垂直に立設され、上側加圧板3の四隅の穴部3aを貫通する4本の ボルト7と、ボルト7の先端に螺合することにより加圧板3,5の離隔距離を規 定するナット9とを備えている。即ち、ボルト7およびナット9は拘束部材に相 当する。The brazing jig 1 is erected vertically from the square upper pressure plate 3 and the lower pressure plate 5 and the four corners of the lower pressure plate 5, and penetrates through the holes 3 a at the four corners of the upper pressure plate 3. It is provided with four bolts 7 and a nut 9 which is screwed onto the tip of the bolt 7 to determine the distance between the pressure plates 3 and 5. That is, the bolt 7 and the nut 9 correspond to the restraining member.
【0015】 ろう付け治具1はこの他、次のように形成されたバネ受け11および13と、 弾発部材としてのコイルバネ15および19とを備えて構成されている。バネ受 け11は、窪み53a背面の偏平部分に沿った円環状の平板である。バネ受け1 3は窪み53aが形成する円環の内径とほぼ等しい直径の円板である。コイルバ ネ15はバネ受け11の内径と外径とのほぼ中間の直径を有し、コイルバネ19 はバネ受け13の外径とほぼ等しい直径を有している。またコイルバネ15とコ イルバネ19とのバネ定数の比はバネ受け11とバネ受け13との面積比に等し く、コイルバネ19の自然長はコイルバネ15の自然長よりも窪み53aの深さ 分だけ長い。In addition to this, the brazing jig 1 is configured to include spring receivers 11 and 13 formed as follows, and coil springs 15 and 19 as elastic members. The spring receiver 11 is an annular flat plate along the flat portion on the back surface of the recess 53a. The spring receiver 13 is a disk having a diameter substantially equal to the inner diameter of the ring formed by the depression 53a. The coil vane 15 has a diameter approximately in the middle of the inner diameter and the outer diameter of the spring receiver 11, and the coil spring 19 has a diameter substantially equal to the outer diameter of the spring receiver 13. The ratio of the spring constants of the coil spring 15 and the coil spring 19 is not equal to the area ratio of the spring receiver 11 and the spring receiver 13, and the natural length of the coil spring 19 is smaller than the natural length of the coil spring 15 by the depth of the recess 53a. long.
【0016】 このように構成されたろう付け治具1では、前述の熱交換器51を製造する際 、熱交換器51を構成する各部材(円板53,台座55,コルゲートフィン59 および61)を次のように組み付けて使用される。先ず、下側加圧板5の上に、 熱交換器51を構成する各部材53〜61を前述の順序で積層載置する。続いて バネ受け11を最上部に積層された円板53の窪み53a背面の偏平部分に載置 する。また、バネ受け13をその円板53中央の偏平部分に載置する。In the brazing jig 1 configured as described above, when manufacturing the heat exchanger 51 described above, each member (the disk 53, the pedestal 55, the corrugated fins 59 and 61) that constitutes the heat exchanger 51 is It is assembled and used as follows. First, the members 53 to 61 forming the heat exchanger 51 are stacked and mounted on the lower pressure plate 5 in the order described above. Subsequently, the spring receiver 11 is placed on the flat portion of the back surface of the recess 53a of the disk 53 stacked on top. Further, the spring receiver 13 is placed on the flat portion in the center of the disc 53.
【0017】 更に、バネ受け11上にコイルバネ15を、バネ受け13上にコイルバネ19 を、それぞれ同心円状に載置した後、各コイルバネ15,19の上から上側加圧 板3を載置する。なお、このとき上側加圧板3の穴部3aに各ボルト7を貫通さ せる。そして最後に、各穴部3aを貫通したボルト7にナット9をそれぞれ螺合 させ、各部材53〜61の間にろう付けに充分な圧力が加わるまでナット9を締 め付ける。Further, after the coil spring 15 is placed on the spring receiver 11 and the coil spring 19 is placed on the spring receiver 13 concentrically, the upper pressure plate 3 is placed on the coil springs 15 and 19. At this time, the bolts 7 are inserted into the holes 3a of the upper pressure plate 3. Then, finally, the nuts 9 are screwed into the bolts 7 penetrating the holes 3a, respectively, and the nuts 9 are tightened until sufficient pressure is applied between the members 53 to 61 for brazing.
【0018】 ナット9を締め付けて行くとき、各円板53の間には次のようにして均等な圧 力が加わる。即ち、コイルバネ19の自然長はコイルバネ15の自然長よりも窪 み53aの深さ分だけ長いので、コイルバネ15および19の圧縮量は互いに等 しい。更に、コイルバネ15とコイルバネ19とのバネ定数の比はバネ受け11 とバネ受け13との面積比に等しいので、コイルバネ15がバネ受け11を介し て円板53に加える圧力と、コイルバネ19がバネ受け13を介して円板53に 加える圧力とが等しくなるのである。When the nut 9 is tightened, a uniform pressure is applied between the discs 53 as follows. That is, since the natural length of the coil spring 19 is longer than the natural length of the coil spring 15 by the depth of the depression 53a, the compression amounts of the coil springs 15 and 19 are equal to each other. Further, since the ratio of the spring constants of the coil spring 15 and the coil spring 19 is equal to the area ratio of the spring receiver 11 and the spring receiver 13, the pressure applied by the coil spring 15 to the disk 53 via the spring receiver 11 and the coil spring 19 are the springs. The pressure applied to the disk 53 via the receiver 13 becomes equal.
【0019】 このように、熱交換器51を構成する各部材53〜61をろう付け治具1に組 み付けて加圧拘束した後、ろう付け治具1ごと加熱すれば、各部材53〜61の ろう付けを行なうことができる。なお、このとき各部材53〜61に加わる圧力 は、ナット9の締め具合いによって容易に調整することができる。As described above, after the respective members 53 to 61 that constitute the heat exchanger 51 are assembled to the brazing jig 1 and pressure-restrained, the entire brazing jig 1 is heated. 61 brazes can be made. The pressure applied to each member 53 to 61 at this time can be easily adjusted by the tightness of the nut 9.
【0020】 また、本実施例のろう付け治具1では、コイルバネ15が一本で円板53の周 縁部全体を均一に加圧するので、円板37周縁部に多数のコイルバネを配設する 場合に比べて必要なバネの数を減らして各部材53〜61の組み付け作業を能率 向上させることができる。更に、大径のコイルバネ15は円板53の周縁部全体 を均一に加圧することができるので、円板37周縁部に加わる圧力がバラ付くの を良好に防止することができる。In addition, in the brazing jig 1 of the present embodiment, since the single coil spring 15 uniformly presses the entire peripheral portion of the disc 53, a large number of coil springs are arranged in the peripheral portion of the disc 37. Compared to the case, the number of required springs can be reduced and the assembling work of the members 53 to 61 can be improved efficiently. Further, since the large-diameter coil spring 15 can uniformly press the entire peripheral portion of the disc 53, it is possible to favorably prevent the pressure applied to the peripheral portion of the disc 37 from varying.
【0021】 また更に、本実施例のろう付け治具1では、コイルバネ19の自然長をコイル バネ15の自然長よりも窪み53aの深さ分だけ長くしている。このため、円板 53に凹凸があり、しかも、窪み53a背面より窪み込んだ部分にコイルバネ1 9を配設しなければならないにも関わらず、スペーサを使用することなく円板5 3に均一な圧力を加えることができる。従って各部材53〜61の組み付け作業 を一層能率向上させることができる。この結果、各部材53〜61のろう付け作 業全体の作業能率を飛躍的に向上させることができる。Furthermore, in the brazing jig 1 of the present embodiment, the natural length of the coil spring 19 is made longer than the natural length of the coil spring 15 by the depth of the recess 53a. Therefore, even though the disk 53 has irregularities and the coil spring 19 must be disposed in the recessed portion from the back surface of the recess 53a, the disk 53 is evenly formed on the disk 53 without using a spacer. Pressure can be applied. Therefore, the work of assembling the members 53 to 61 can be further improved. As a result, the work efficiency of the entire brazing operation of the members 53 to 61 can be dramatically improved.
【0022】 また、本実施例のろう付け治具1では、コイルバネ15,19の弾発力をバネ 受け11,13を介して円板53に加えているので、各部材53〜61をより均 一に加圧することができる。このため、ろう付け後の熱交換器51に、傾きや寸 法のバラツキ、ろう付け不良などが発生しない。Further, in the brazing jig 1 of the present embodiment, since the elastic force of the coil springs 15 and 19 is applied to the disk 53 via the spring receivers 11 and 13, the members 53 to 61 are more evenly distributed. It can be pressurized to one. For this reason, the heat exchanger 51 after brazing does not have inclination, variation in size, or defective brazing.
【0023】 なお、上記実施例では上側加圧板3,コイルバネ15および19,並びにバネ 受け11および13を別体に設けているが、これらの部材は予め溶接するなどし て一体に形成しておいてもよい。このように構成した場合、下側加圧板5上に各 部材53〜61を積層した後、ボルト7が穴部3aを貫通するように上側加圧板 3を載置してナット9を締め付ければよい。すると、このような極めて簡単な作 業によって各部材53〜61をろう付け治具1に組み付けることができる。In the above embodiment, the upper pressure plate 3, the coil springs 15 and 19, and the spring receivers 11 and 13 are provided separately, but these members are integrally formed by welding in advance. You may stay. In this case, after stacking the members 53 to 61 on the lower pressure plate 5, the upper pressure plate 3 is placed so that the bolt 7 penetrates the hole 3a and the nut 9 is tightened. Good. Then, the members 53 to 61 can be assembled to the brazing jig 1 by such an extremely simple operation.
【0024】 次に、本実施例のろう付け治具1と、従来から使用されている比較例のろう付 け治具101とを用いて熱交換器51を製造し、以下に示す比較を行った。 先ず、ろう付け治具101を次のように構成した。図3の平面図および図4の B−B線断面図に示すように、円環状のバネ受け11に替えて、一辺の長さがコ イルバネ19の外径とほぼ等しい正方形の四枚のバネ受け111を設けた。また 、コイルバネ15,19に替えて、自然長がコイルバネ15と等しく半径がコイ ルバネ19と等しい五本のコイルバネ119を設けた。また、窪み53aの深さ と同じ厚さを有するスペーサ121を新たに設けた。この他の部分はろう付け治 具1と同様に構成したので、各部に同一の符号を付して構成の詳細な説明を省略 する。Next, a heat exchanger 51 was manufactured using the brazing jig 1 of the present example and the brazing jig 101 of the comparative example that has been conventionally used, and the following comparisons are performed. It was First, the brazing jig 101 was constructed as follows. As shown in the plan view of FIG. 3 and the sectional view taken along the line BB of FIG. 4, four square springs each having a side length substantially equal to the outer diameter of the coil spring 19 are used instead of the annular spring receiver 11. A receiver 111 is provided. Further, in place of the coil springs 15 and 19, five coil springs 119 having a natural length equal to that of the coil spring 15 and a radius equal to that of the coil spring 19 are provided. Further, a spacer 121 having the same thickness as the depth of the depression 53a is newly provided. Since the other parts are configured similarly to the brazing tool 1, the same reference numerals are given to the respective parts and detailed description of the structure is omitted.
【0025】 このように構成されたろう付け治具101では、下側加圧板5の上に熱交換器 51を構成する各部材53〜61を積層載置した後、窪み53a背面の偏平部に 各バネ受け111を90°おきに載置する。各バネ受け111上にはコイルバネ 119をそれぞれ載置する。また円板53中央には、バネ受け13,コイルバネ 119を順次載置し、更ににその上にスペーサ121を載置する。そして、窪み 53a背面のコイルバネ119およびスペーサ121の上から上側加圧板3を載 置した後ナット9を締め付けることによって組み付けが完了する。In the brazing jig 101 configured as described above, after the members 53 to 61 that constitute the heat exchanger 51 are stacked and mounted on the lower pressure plate 5, each of the members 53 to 61 is placed on the flat portion on the back surface of the recess 53 a. The spring receivers 111 are placed every 90 °. A coil spring 119 is placed on each spring receiver 111. Further, a spring receiver 13 and a coil spring 119 are sequentially mounted on the center of the disc 53, and a spacer 121 is further mounted thereon. Then, the upper pressing plate 3 is placed on the coil spring 119 and the spacer 121 on the back surface of the recess 53a, and then the nut 9 is tightened to complete the assembly.
【0026】 前述の実施例のろう付け治具1と、比較例のろう付け治具101とを用いて熱 交換器51を製造した場合の組み付け時間などの比較を表1に示す。なお表1で は、上側加圧板3,コイルバネ15および19,並びにバネ受け11および13 を一体に設けたろう付け治具1を実施例A、それらを別体に設けたろう付け治具 1を実施例Bとしている。また各例では、円板53および台座55をブレージン グシート:BA12PCで、コルゲートフィン59,61をアルミニウム合金: A3003でそれぞれ構成し、直径80mm,高さ100mmの大きさの熱交換器5 1を製造した。更に、各例のろう付け条件としては、フッ化物系フラックスを使 用したろう付け方法を採用し、窒素ガス雰囲気で595℃にてろう付けを行った 。Table 1 shows a comparison of the assembling time and the like when the heat exchanger 51 is manufactured using the brazing jig 1 of the above-described example and the brazing jig 101 of the comparative example. In Table 1, the brazing jig 1 in which the upper pressure plate 3, the coil springs 15 and 19, and the spring receivers 11 and 13 are integrally provided is the embodiment A, and the brazing jig 1 in which the brazing jigs 1 are separately provided is the embodiment.

【0028】 表1から判るように、実施例A,Bのろう付け治具1では部品点数が少ないた め組み付け時間を良好に短縮することができ、このためろう付け作業全体の能率 を向上させることができる。特に実施例Aでは部品がただ一つであり、コイルバ ネ15,19の位置決め作業も不要であるので、極めて良好に能率を向上させる ことができる。また実施例A,Bでは、部品点数が少ないため組み付け作業中に 各部品の配設位置がずれたりするのを防止することができる。更に、コイルバネ 15が円板53の周縁部全体を均一に加圧するので、製造された熱交換器51に ろう付け不良や傾きが生じるのを良好に防止することができる。また、実施例A またはBのろう付け治具1にて熱交換器51を製造する場合、前述のように組み 付け作業が極めて簡略化されるので、組み付け作業を自動化して能率を一層向上 させることもできる。As can be seen from Table 1, since the brazing jigs 1 of Examples A and B have a small number of parts, the assembling time can be shortened satisfactorily, thus improving the efficiency of the whole brazing operation. be able to. Particularly, in the embodiment A, since there is only one part and the positioning work of the coil panels 15 and 19 is unnecessary, the efficiency can be improved very favorably. Further, in Examples A and B, since the number of parts is small, it is possible to prevent the arrangement position of each part from being displaced during the assembling work. Further, since the coil spring 15 uniformly presses the entire peripheral portion of the disk 53, it is possible to favorably prevent the manufactured heat exchanger 51 from being defective in brazing or tilting. Further, when the heat exchanger 51 is manufactured by the brazing jig 1 of the embodiment A or B, the assembling work is extremely simplified as described above, so that the assembling work is automated to further improve the efficiency.

【0029】 なお上記各実施例では、円板53周縁部を加圧する大径のコイルバネ15の内 側に小径のコイルバネ19を配設すると共に、コイルバネ19の自然長をコイル バネ15の自然長よりも窪み53aの深さ分だけ長くしている。即ち上記各実施 例のろう付け治具1は、第1考案の構成と第2考案の構成とを兼ね備えているが 、次のような構成を採用しても一応の能率向上が図れる。In each of the above-described embodiments, the coil spring 19 having a small diameter is arranged inside the coil spring 15 having a large diameter that presses the peripheral edge of the disc 53, and the natural length of the coil spring 19 is smaller than the natural length of the coil spring 15. The length is also increased by the depth of the depression 53a. That is, the brazing jig 1 of each of the above-mentioned embodiments has both the structure of the first invention and the structure of the second invention, but even if the following structure is adopted, the efficiency can be improved to some extent.
【0030】 例えば、コイルバネ15および19の自然長を同一にし、コイルバネ19の上 に、ろう付け治具101のスペーサ121を載置してもよい。この場合、円板5 3の周縁部全体を一つのコイルバネ15によって均一に加圧することができるの で、必要となるコイルバネの数を減らして組み付け作業の能率を向上させること ができる。For example, the coil springs 15 and 19 may have the same natural length, and the spacer 121 of the brazing jig 101 may be placed on the coil spring 19. In this case, the entire periphery of the disk 53 can be uniformly pressed by the single coil spring 15, so that the number of required coil springs can be reduced and the efficiency of the assembling work can be improved.
【0031】 また、窪み53a背面の偏平部にろう付け治具101の四つのバネ受け111 を載置し、その上にコイルバネ19と同一のバネ定数でかつコイルバネ19より も窪み53aの深さ分だけ短い自然長のコイルバネをそれぞれ配設してもよい。 この場合、スペーサ121を用いることなく円板53の各部に均一な圧力を加え ることができるので組み付け作業の能率を向上させることができる。Further, the four spring bearings 111 of the brazing jig 101 are placed on the flat portion on the back surface of the recess 53 a, and the spring constant of the coil spring 19 is equal to that of the coil spring 19 and the depth of the recess 53 a is larger than that of the coil spring 19. You may arrange | position the coil spring of the natural length short only for each. In this case, since uniform pressure can be applied to each part of the disk 53 without using the spacer 121, the efficiency of the assembling work can be improved.
【0032】 更に後者の構成において、バネ受け111上に配設するコイルバネを前述の自 然長とする代わりにそのコイルバネのバネ定数を適当に設定し、ナット9を締め 付けたときの弾発力がそのときのコイルバネ19の弾発力と一致するようにして もよく、同様の作用・効果が得られる。Further, in the latter configuration, the spring constant of the coil spring disposed on the spring receiver 111 is appropriately set instead of having the above-described natural length, and the elastic force when the nut 9 is tightened is set. May be made to match the elastic force of the coil spring 19 at that time, and the same action and effect can be obtained.
【0033】 一方上記各実施例では、上下一対の加圧板3,5の間に被ろう付け部材として の各部材53〜61を配設して上下方向に加圧しているが、本考案はろう付け部 材を水平方向に加圧するろう付け治具にも適用することができる。また上記各実 施例では、コイルバネ15,19の弾発力をバネ受け11,13を介して円板5 3に加えることによって各部材53〜61を一層均一に加圧しているが、バネ受 け11,13は特に設けなくてもよく、コイルバネ15,19を直接円板53に 当接させてもよい。更に本考案は、円板53の周縁部と中央とで凹凸が逆になっ た製品や、円形以外の製品など種々の金属製品に適用することができる。On the other hand, in each of the above embodiments, the members 53 to 61 as the members to be brazed are disposed between the pair of upper and lower pressure plates 3 and 5 to apply pressure in the vertical direction. It can also be applied to a brazing jig that presses the brazing material horizontally. Further, in each of the above embodiments, the elastic force of the coil springs 15 and 19 is applied to the disk 53 through the spring receivers 11 and 13 to press the members 53 to 61 more uniformly. The cages 11 and 13 may not be provided in particular, and the coil springs 15 and 19 may be directly brought into contact with the disc 53. Furthermore, the present invention can be applied to various metal products such as products in which the peripheral portion and the center of the circular plate 53 are reversed, and products other than circular products.

【考案の効果】 以上詳述したように第1考案では、大径のコイルバネを被ろう付け部材表面に 配設して一対の加圧板の離隔距離を規定するだけで、被ろう付け部材周縁部全体 を均一に加圧することができる。即ち、被ろう付け部材周縁部全体を加圧するた めに一本のコイルバネを配設するだけでよい。このため被ろう付け部材表面に配 設しなければならないバネの数を減らすことができ、従って被ろう付け部材が大 型である場合にも簡単にろう付け治具に組み付けることができる。As described above in detail, in the first invention, the coil spring having a large diameter is arranged on the surface of the brazed member, and only the distance between the pair of pressure plates is regulated. The whole can be pressed uniformly. That is, it is only necessary to dispose one coil spring to pressurize the entire periphery of the brazed member. Therefore, the number of springs that must be arranged on the surface of the brazed member can be reduced, and therefore, even when the brazed member is large, it can be easily assembled to the brazing jig.
【0035】 また第2考案では、複数の弾発部材を被ろう付け部材表面の所定場所に配設し て一対の加圧板の離隔距離を規定するだけで、被ろう付け部材に凹凸がある場合 でも被ろう付け部材端面に同一の圧力を加えることができる。このため、被ろう 付け部材端面の窪み込んだところにも弾発部材を配設しなければならない場合で あっても、スペーサを使用することなく簡単にその被ろう付け部材をろう付け治 具に組み付けることができる。Further, in the second invention, when the plurality of elastic members are arranged at predetermined positions on the surface of the brazed member and the separation distance between the pair of pressure plates is regulated, the brazed member has unevenness. However, the same pressure can be applied to the end surface of the brazed member. For this reason, even if it is necessary to dispose the elastic member even in the recess of the end surface of the brazed member, the brazed member can be easily attached to the brazing jig without using a spacer. Can be assembled.
【0036】 従って、第1または第2考案のろう付け治具を使用すれば、ろう付け部材を加 圧拘束するために必要な部品点数を減らすことができる。このため、被ろう付け 部材の組み付け作業を能率的に行なって、ろう付け作業全体の作業能率を向上さ せることができる。Therefore, by using the brazing jig of the first or second invention, it is possible to reduce the number of parts required to press and restrain the brazing member. Therefore, the work of assembling the brazed members can be efficiently performed, and the work efficiency of the whole brazing work can be improved.
