Description

本発明は、一般にプレスブレーキと称せられる板金材を成形加工する機械において上金型を保持する装置に関する。  The present invention relates to an apparatus for holding an upper die in a machine for forming and processing a sheet metal material generally called a press brake.

周知の通り、板金材の成型加工等を行なうプレスブレーキは、プレスブレーキの上部テーブルに装着される上金型とプレスブレーキの下部テーブル上に装着される下金型とを有して成るものであり、上記上金型の先端と下金型の溝部を噛み合わせることによってワークの加工を行なうものである。
そして、上記プレスブレーキに使用される上金型は、プレスブレーキの上部テーブルに取り付けられた金型ホルダー装置に取り付けられる。しかし、箱状の製品を作る場合においては、長手方向に保持溝を持ち、かつ長手方向に分割された、複数個の上金型を金型ホルダー装置に取り付けることになるが、この際上記上金型がそれぞれ均等に締め付けられず、幾つかの分割された上金型が、上金型の保持溝の上面が金型ホルダー装置の締金に設けられたストッパー部に当たるまで約1〜2mm下降したりすることも有り、作業性も悪く危険であった。
As is well known, a press brake for forming a sheet metal material has an upper mold mounted on the upper table of the press brake and a lower mold mounted on the lower table of the press brake. Yes, the workpiece is machined by engaging the tip of the upper mold and the groove of the lower mold.
And the upper metal mold | die used for the said press brake is attached to the metal mold | die holder apparatus attached to the upper table of a press brake. However, when making a box-shaped product, a plurality of upper molds having a holding groove in the longitudinal direction and divided in the longitudinal direction are attached to the mold holder device. The molds are not clamped evenly, and several divided upper molds are lowered by about 1 to 2 mm until the upper surface of the upper mold holding groove hits a stopper provided on the mold holder device clamp. The workability was poor and it was dangerous.

上記従来技術による長手方向に保持溝を持つ上金型の落下を防ぎ装着し、作業の安全性を高め金型ホルダー装置の機能向上を図ることにある。  An object of the present invention is to prevent the upper mold having the holding groove in the longitudinal direction from being dropped and to mount it, thereby improving the safety of the work and improving the function of the mold holder device.

上記目的を達成する為に、本発明は次の技術的手段を有する。長手方向に保持溝をもつ上金型の上記保持溝上部の面に接し、正面から見て前後に移動可能な金型保持面を持つ金型保持部材を持つか又は、上記保持溝上部の面に接する突起部を持ち、締付ボルト等による締め付け力を金型の締付面に伝える金型締付面を持つと共に、締付時にホルダー本体にボルト等で支持され、バネ等により蓄勢される傾斜部を持つ部材に滑合する傾斜部を持つ部材を有し、金型締付時締付方向及び上方に移動する締金を持つ金型ホルダー装置である。  In order to achieve the above object, the present invention has the following technical means. A mold holding member having a mold holding surface that is movable in the front-rear direction when viewed from the front or in contact with the upper groove holding surface of the upper mold having a holding groove in the longitudinal direction, or the upper holding groove surface. Has a mold clamping surface that transmits the clamping force of the clamping bolt to the clamping surface of the mold, and is supported by the holder body with bolts and the like, and is stored by a spring etc. A mold holder device having a member having an inclined portion that slides on a member having an inclined portion and having a clamp that moves upward in the mold clamping direction and moves upward.

上記締金を持つ金型ホルダー装置に、長手方向に保持溝を持つ上金型を入れるときは、締付ボルトを反時計方向に廻し、上記金型の保持溝上部の面を金型保持部材の金型保持面(金型保持部材を持たない場合は、突起部の金型保持面)に載せ横から入れるか、上記金型を金型保持部材とホルダー本体との間に下方から入れ、上記金型の保持溝上部の面を金型保持部材の金型保持面(金型保持部材を持たない場合は、突起部の金型保持面)に載せる。この状態で締付ボルトを時計方向に廻し締め付けると、締金の背面に取り付けられ傾斜部を持つ部材が、ホルダー本体にボルト等で支持されバネ等で蓄勢される傾斜部を持つ部材に接合している為、上記金型を上方向に持ち上げた状態で締め付けることになり、締付前にあった締金の締付面と上記金型の締付面の隙間、及びホルダー本体の下面と上記金型の負荷面との隙間もなくなった状態で上記金型は締付保持され、落下はしない。
金型保持部材を持つ締金では、長手方向に保持溝を持たない上金型も同様に横又は下方から金型ホルダー装置に入れることができ、金型締付時には、金型保持部材は締金本体に設けられた溝部の中に移動し、上記上金型は装着される。
When inserting the upper mold having the holding groove in the longitudinal direction into the mold holder apparatus having the above-mentioned clamp, turn the tightening bolt counterclockwise so that the upper surface of the mold holding groove is the mold holding member. Put it on the mold holding surface (the mold holding surface of the protrusion if there is no mold holding member) from the side or insert the mold from below between the mold holding member and the holder body, The upper surface of the mold holding groove is placed on the mold holding surface of the mold holding member (or the mold holding surface of the protrusion when no mold holding member is provided). When the tightening bolt is turned clockwise in this state, the member with the inclined part attached to the back of the clamp is joined to the member with the inclined part that is supported by the holder body with the bolt and stored by the spring. Therefore, the mold is tightened in the upwardly lifted state, and the gap between the clamping surface of the clamping mold and the clamping surface of the mold before the clamping, and the lower surface of the holder body The mold is clamped and held without any gap with the load surface of the mold, and does not fall.
In the case of a clamp having a mold holding member, an upper mold having no holding groove in the longitudinal direction can be similarly inserted into the mold holder device from the side or from the bottom, and when the mold is clamped, the mold holding member is clamped. It moves into a groove provided in the metal body, and the upper mold is mounted.

以下、本発明の理解を容易にする為に、添付図面に使用した符号を用いて全体構成について説明する。    Hereinafter, in order to facilitate understanding of the present invention, the overall configuration will be described using reference numerals used in the accompanying drawings.

図面を参照するに、本発明の実施に係るプレスブレーキ用金型ホルダー装置は、全体的に数字1で示してあり、板金材を成形加工するプレスブレーキにおいて上金型3を保持するものであり、プレスブレーキの前面上部にある水平の長い形状の支持部材5(上部テーブルとも言う)に、公知の方法により、懸垂する状態にて装着される。なお、説明の進行によって理解されるとおり、第1図、第2図、第3図、および第5図においては、上金型3は、金型ホルダー装置1によって保持されるべき位置にあるが、未だ最終的に保持されない状態として示されている。  Referring to the drawings, a press brake die holder device according to an embodiment of the present invention is generally indicated by numeral 1 and holds an upper die 3 in a press brake for forming a sheet metal material. Then, it is attached to a horizontally long support member 5 (also referred to as an upper table) in the upper front portion of the press brake in a suspended state by a known method. As will be understood from the progress of the description, in FIGS. 1, 2, 3, and 5, the upper mold 3 is in a position to be held by the mold holder device 1. It is shown as a state that has not yet been finally held.

特に第1図において、金型ホルダー装置1は、複数個のボルト7とスプリングピン9によって矩形の板11に固定されており、その矩形の板11は公知の方法によってプレスブレーキの支持部材(上部テーブルとも言う)に取り付けられている。また、公知の技術として、楔15が、金型ホルダー装置1の上方部にプレスブレーキの支持部材5の下面に接する状態で、板11にボルト17により座金19を介して固定されている。因に、第2図に示すとおり、ボルト17が通る板11の穴の開口部で座金19がある部分は、楔15の水平に移動により、板11が上下に動けるように形成されている。なお、図示を省略するが、周知のとおり、プレスブレーキの支持部材5(上部テーブルとも言う)の直下には、一般にテーブルと称する支持部材があり、その上に、板金材を成形加工するために上金型3と協働する下金型が装着される。かくて、成形加工されるべき板金材が下金型上に載置され、それを成形加工するために、上金型3を支持する支持部材5と下金型を支持する下方の支持部材のいずれかが他方に対して垂直に駆動される。なお、第1図において、金型ホルダー装置1と上金型3はそれぞれ1個だけ示してあるが、幅の広い板金材を成形加工するためには、複数個の分割された上金型が第1図の左右方向に連結されて用いられ、この為に、複数個の金型ホルダー装置1が用いられる。  In particular, in FIG. 1, the mold holder device 1 is fixed to a rectangular plate 11 by a plurality of bolts 7 and spring pins 9, and the rectangular plate 11 is supported by a press brake support member (upper part) by a known method. It is also attached to the table. As a well-known technique, the wedge 15 is fixed to the plate 11 with a bolt 17 through a washer 19 in a state where the wedge 15 is in contact with the lower surface of the support member 5 of the press brake at the upper part of the mold holder device 1. Incidentally, as shown in FIG. 2, the portion where the washer 19 is located at the opening of the hole of the plate 11 through which the bolt 17 passes is formed so that the plate 11 can be moved up and down by the horizontal movement of the wedge 15. Although not shown, as is well known, there is a support member generally called a table directly below the support member 5 (also referred to as the upper table) of the press brake, on which a sheet metal material is formed. A lower mold that cooperates with the upper mold 3 is mounted. Thus, the sheet metal material to be molded is placed on the lower mold, and in order to mold it, the support member 5 that supports the upper mold 3 and the lower support member that supports the lower mold One is driven perpendicular to the other. In FIG. 1, only one mold holder device 1 and one upper mold 3 are shown. However, in order to form a wide sheet metal material, a plurality of divided upper molds are used. For this purpose, a plurality of mold holder devices 1 are used.

周知のとおり、上金型3は、上部に装着のためのシャンク部3sを有し、板金材の成形加工時の加重を受けるように、そのシャンク部3sの根本に、肩状に水平な負荷面3fが形成されている。また、上金型3は、周知のとおり、一般に、落下に備える安全対策として、長手方向に断面が矩形の落下防止用の保持溝3gが形成されている。ただし、後述のとおり、本金型ホルダー装置1は、上金型3が保持溝3gを有すると否とにかかわらず、これを保持することができる。  As is well known, the upper die 3 has a shank portion 3s for mounting on the upper portion, and a shoulder-like horizontal load is applied to the root of the shank portion 3s so as to receive a load at the time of forming the sheet metal material. A surface 3f is formed. In addition, as is well known, the upper mold 3 is generally provided with a holding groove 3g for preventing the fall having a rectangular cross section in the longitudinal direction as a safety measure for falling. However, as will be described later, the mold holder device 1 can hold the upper mold 3 regardless of whether or not the upper mold 3 has the holding groove 3g.

特に第1図、第2図および第3図に明示されるとおり、金型ホルダー装置1は、ホルダー本体21を有し、これは、プレスブレーキの左右方向に長く上下方向に短く前後方向に薄い直方体状の部材である。ただし、本実施例において、ホルダー本体21は、第1図にて見られるとおり、上面が傾斜を成し楔15に接し、ボルト17を緩め楔15を水平に動かすことにより、高さを調整できるように構成されている。ホルダー本体21は、下面に、長い直方体状の金型保持部23が形成されており、これは、前後に、上金型3を受ける垂直の金型保持面23fおよび23rを有する。なお、上金型3は、図示においてはホルダー本体21の金型保持部23の前部金型保持面23fにて保持されるが、成形加工される板金材の寸法や形状等により、前後の金型保持面23fおよび23rのいずれかで保持される。ただし、上金型3は、普通はホルダー本体21の前部で保持するのが便利であるので、本実施例においては、金型ホルダー21は、主として、前部金型保持面23f側で保持するように構成されている。    In particular, as clearly shown in FIGS. 1, 2, and 3, the mold holder device 1 has a holder body 21, which is long in the left-right direction of the press brake and short in the vertical direction and thin in the front-back direction. It is a rectangular parallelepiped member. However, in this embodiment, as seen in FIG. 1, the holder body 21 can be adjusted in height by inclining the upper surface and contacting the wedge 15, loosening the bolt 17 and moving the wedge 15 horizontally. It is configured as follows. The holder main body 21 is formed with a long rectangular parallelepiped mold holding portion 23 on the lower surface, which has vertical mold holding surfaces 23f and 23r for receiving the upper mold 3 at the front and rear. The upper mold 3 is held by the front mold holding surface 23f of the mold holding section 23 of the holder main body 21 in the drawing, but depending on the size and shape of the sheet metal material to be processed, It is held by one of the mold holding surfaces 23f and 23r. However, since it is convenient to hold the upper mold 3 at the front part of the holder main body 21, in this embodiment, the mold holder 21 is mainly held at the front mold holding surface 23f side. Is configured to do.

特に第1図、第2図、第3図および第5図に明示されるとおり、上金型3をホルダー本体21の金型保持部23にて保持するために、その前後に、すなわち第2図および第3図において金型保持部23の両側に、長方形の板状の締め金25および27が金型保持部23に平行に備えられている。締め金25および27は、それぞれ、その下端部に締付部25hおよび27hを有し、締付けボルト6及び6′によって水平の状態で保持され、それらの締付部25hおよび27hがそれぞれ金型保持部23の金型保持面23fと23rに対して上金型3を押し当て保持できるように構成されている。
又、締め金25および27はその背面に設けられた溝10に隙間なく組込まれ、止めねじ8で保持された傾斜部(正面から見て矩形)を持つ部材4を有する、上記部材4の傾斜部に滑合する傾斜部を持つ部材2(正面から見て矩形または丸)は、皿バネ12を介して上記部材4を持つ締め金25及び27と共に締付ボルト6及び6´によってホルダー本体21に装着されている。締付ボルト6及び6′が通る部材4の穴は図1及び図2が示すように、穴部上方は締付ボルト6及び6′の上部に接しており、下部は締め金25及び27が部材4と共に上昇しても締付ボルト6及び6′の下部には接しない。
締金25は、締金27を締付ボルト6′で締め付けるために、工具を入れる穴29を有する。本実施例に於いては、穴29は第1図に示すとおり締金25に2箇所それぞれ同じ高さに設けられている。
In particular, as clearly shown in FIGS. 1, 2, 3, and 5, in order to hold the upper mold 3 by the mold holding portion 23 of the holder body 21, before and after that, that is, the second In FIG. 3 and FIG. 3, rectangular plate-like clamps 25 and 27 are provided in parallel to the mold holding part 23 on both sides of the mold holding part 23. The clamps 25 and 27 have clamping portions 25h and 27h at their lower ends, respectively, and are held in a horizontal state by the clamping bolts 6 and 6 ', and these clamping portions 25h and 27h are respectively held by the mold. The upper mold 3 can be pressed and held against the mold holding surfaces 23f and 23r of the portion 23.
In addition, the clamps 25 and 27 are assembled into the groove 10 provided on the back surface thereof without any gap, and have the member 4 having the inclined portion (rectangular when viewed from the front) held by the set screw 8. The member 2 (rectangular or round when viewed from the front) having an inclined portion that slides on the holder is clamped by the clamping bolts 6 and 6 'together with the clamps 25 and 27 having the member 4 via the disc spring 12. It is attached to. As shown in FIGS. 1 and 2, the hole of the member 4 through which the fastening bolts 6 and 6 'pass is in contact with the upper part of the fastening bolts 6 and 6' in the upper part of the hole and the fasteners 25 and 27 in the lower part. Even if it rises with the member 4, it does not contact the lower part of the fastening bolts 6 and 6 '.
The clamp 25 has a hole 29 for inserting a tool in order to tighten the clamp 27 with the tightening bolt 6 '. In this embodiment, the holes 29 are provided at the same height at two locations on the clamp 25 as shown in FIG.

特に第1図、第2図および第3図にて見られるとおり、締め金25および27は、いずれも、その下端部の締め付け部25hおよび27hに、その全長に亘って水平に長手方向の溝25gおよび27gが形成されており、その溝25gおよび27gに、金型保持部材61を有する。金型保持部材61は、締め金25および27とほぼ同じ長さの部材であり、水平な金型保持面61hおよび傾斜面61sを有し、締め金25および27の溝25gおよび27gに、複数個のネジ63によって水平に移動可能に保持され、かつ、ばね64によって上金型3の方向に締め金25および27から突出するように蓄勢されている。すなわち、金型保持部材61は、締め金25および27の締め付け部25hおよび27hに形成された溝25gおよび27gに、出没自在に備えられている。金型保持部材61は、上金型3に保持溝3gがある場合に、上金型3を保持溝3gによって保持するものものであり、上金型3の万一の落下に備えるとともに、上金型3を締め金25または27により最終的に締め付け保持する前に仮に保持するものである。このために、金型保持部材61は、第2図および第3図に示すとおり、保持溝3gのある金型3が締め金25または27とホルダー本体21の金型保持部23との間に締め付け保持されるべき位置にある時、上金型3の保持溝3g内に位置し、その金型保持面61hが保持溝3gの上部面により上金型3を保持できるように構成される。なお、金型保持部材61の金型保持面61hは、上金型3の保持溝3gの上部面に当接し上金型3を保持するものであり、また、金型保持部材61の傾斜面61sは、カムの働きをなし、例えば上金型3が装着時に当接すれば、金型保持部材61はばね64に抗して締め金25または27内に没入する。上記の構成により、上金型3を締付保持するために、締め付けボルト6が締付方向に回転されれば、締め金25は、第2図において右側に移動しつつ、傾斜部を持つ部材4と皿バネ12により蓄勢された傾斜部を持つ部材2との滑合により上向へ押し上げられる。この様にして締め金25が押し上げられる結果、上金型3は、その保持溝3gに係合する金型保持部材61によって,その負荷面3fがホルダー本体21の金型保持部23の下面に完全に当接まで持ち上げられる。(詳細な説明は省くが、図5に示す金型保持部材61等を持たず金型保持面61hに相当する突起部Bを持つ締め金も同様である。)このような状態で、さらに締め付けボルトを締付方向に廻せば、上記のように上金型3は上方へ移動できないため、傾斜部を持つ部材4と傾斜部を持つ部材2は滑りをとめ、皿バネ12を圧縮しつつ締め付け面25hと金型締め付面23fで上金型3を締め付け保持する。
因に、上金型3に保持溝3gがない場合、金型保持部材61は、バネ64に抗して締め金25または27に没入させられる。
As can be seen in particular in FIGS. 1, 2 and 3, the clamps 25 and 27 are both longitudinally extending along the entire length of the clamps 25h and 27h at the lower end thereof. 25 g and 27 g are formed, and a mold holding member 61 is provided in the grooves 25 g and 27 g. The mold holding member 61 is a member having substantially the same length as the clamps 25 and 27, has a horizontal mold holding surface 61h and an inclined surface 61s, and a plurality of grooves 25g and 27g in the clamps 25 and 27 are provided. The screw 63 is held so as to be horizontally movable, and is stored by a spring 64 so as to protrude from the clamps 25 and 27 in the direction of the upper mold 3. That is, the mold holding member 61 is provided in the grooves 25g and 27g formed in the tightening portions 25h and 27h of the clamps 25 and 27 so as to be able to appear and retract. The mold holding member 61 holds the upper mold 3 by the holding groove 3g when the upper mold 3 has the holding groove 3g. The mold 3 is temporarily held before the clamp 25 or 27 is finally clamped and held. For this purpose, as shown in FIGS. 2 and 3, the mold holding member 61 has a mold 3 having a holding groove 3g between the clamp 25 or 27 and the mold holding part 23 of the holder body 21. When in the position to be clamped and held, it is located in the holding groove 3g of the upper mold 3, and the mold holding surface 61h is configured to hold the upper mold 3 by the upper surface of the holding groove 3g. Note that the mold holding surface 61 h of the mold holding member 61 abuts on the upper surface of the holding groove 3 g of the upper mold 3 to hold the upper mold 3, and the inclined surface of the mold holding member 61. 61s functions as a cam. For example, if the upper mold 3 comes into contact with the upper mold 3, the mold holding member 61 is immersed in the clamp 25 or 27 against the spring 64. With the above configuration, if the tightening bolt 6 is rotated in the tightening direction in order to tighten and hold the upper mold 3, the clasp 25 moves to the right side in FIG. 4 and the member 2 having the inclined portion accumulated by the disc spring 12 is pushed upward. As a result of the clamp 25 being pushed up in this manner, the upper mold 3 has its load surface 3f on the lower surface of the mold holding portion 23 of the holder main body 21 by the mold holding member 61 engaged with the holding groove 3g. Can be lifted to full contact. (Although a detailed description is omitted, the same applies to a clamp having a protrusion B corresponding to the mold holding surface 61h without having the mold holding member 61 and the like shown in FIG. 5.) If the bolt is turned in the tightening direction, the upper mold 3 cannot move upward as described above. Therefore, the member 4 having the inclined portion and the member 2 having the inclined portion stop slipping and tighten while compressing the disc spring 12. The upper mold 3 is clamped and held by the surface 25h and the mold clamping surface 23f.
Incidentally, when the upper mold 3 does not have the holding groove 3 g, the mold holding member 61 is immersed in the clamp 25 or 27 against the spring 64.

第1図、第3図及び第4図を参照するに、上金型3をホルダー本体21の金型保持部23の後方すなわち第3図において右側にて装着するために、ホルダー本体21の下部に、締め金27を締め付けるための締め付けボルト6′が備えられている。本実施例においては、締め付けボルト6′は、第1図に示すとおり、ホルダー本体21の左右2箇所に、それぞれ同じ高さにて設置され、ホルダー本体21に水平に形成された穴を貫通し、皿バネ12、傾斜部を持つ部材2及び傾斜部を持つ部材4を持つ締め金27を通り、締め金27に設けられた溝部32にスプリングピン30によって係止されたナット31に螺合している。
かくて、金型3の保持溝上部を金型保持面61hにのせ、締め付けボルト6′を締付方向に廻せば、上述のように金型3の負荷面3rがホルダー本体21の金型保持部23の下面に当接する状態で、金型3は締付保持される。
1, 3, and 4, in order to mount the upper mold 3 behind the mold holding portion 23 of the holder body 21, that is, on the right side in FIG. Further, a fastening bolt 6 ′ for fastening the clamp 27 is provided. In the present embodiment, as shown in FIG. 1, the fastening bolts 6 'are installed at the same height at two positions on the left and right sides of the holder body 21, and penetrate through holes formed horizontally in the holder body 21. The plate spring 12, the member 2 having the inclined portion, and the clamp 27 having the member 4 having the inclined portion, and screwed into the nut 31 locked by the spring pin 30 in the groove portion 32 provided in the clamp 27. ing.
Thus, when the upper part of the holding groove of the mold 3 is placed on the mold holding surface 61h and the tightening bolt 6 'is turned in the tightening direction, the load surface 3r of the mold 3 holds the mold of the holder body 21 as described above. The mold 3 is clamped and held in contact with the lower surface of the portion 23.
