Description

本発明は、固定型に対しワークを安全にセット可能にしたリンク機構を用いた横型プレス金型に関する。   The present invention relates to a horizontal press die using a link mechanism that enables a workpiece to be set safely with respect to a fixed die.

従来、縦型プレス機にあっては、ボルスタの上面に固定型が、上下方向に往復移動自在なスライドの下面に可動型が設置されており、ワークは作業員がスライドの下方に手を入れて固定型にセットするのが一般的である（例えば、特許文献１参照）。   Conventionally, in a vertical press machine, a fixed type is installed on the upper surface of the bolster, and a movable type is installed on the lower surface of the slide that can be reciprocated in the vertical direction. In general, it is set to a fixed mold (see, for example, Patent Document 1).

特開平７−３１４１９８号公報Japanese Unexamined Patent Publication No. 7-314198

しかし、上記従来技術にあっては、固定型へのワークセット時に誤ってスライドが下動して手が挟まれしまう可能性を否定できず、更に奥まった場所に手を入れての作業になるため、ワークがセットし難いなど、解決せねばならない課題があった。   However, in the above prior art, it is impossible to deny the possibility that the slide will fall down accidentally when the work is set to the fixed type, and the hand will be pinched. Therefore, there was a problem that had to be solved, such as it was difficult to set the workpiece.

本発明は、上記従来技術に基づく、ワークセット時における誤作動による事故発生や、ワークがセットし難い課題に鑑み、プレス機のボルスタの上面に設置する基板と、該基板の上面における前記スライドより手前の部位に設置する固定型と、前記基板の上面における固定型より後方に前後方向に進退可能に設置した可動型と、プレス機のスライドの直下に固定した押圧板と、前記基板における前記可動型より後方に下端部を軸着した第１リンクと、前記可動型の後端面に下端部を軸着した第２リンクと、前記第１、２リンクの上端部を軸着した、前記押圧板の下面に前後方向にスライド可能に設けた軸受部とを有し、前記プレス機におけるスライドの上下動を水平方向に変換して前記可動型をスライドさせることによって、プレス機のスライドより手前に固定型が設置されることで、スライドの下方に手を入れずにワークをセット可能にして、上記課題を解決する。   The present invention is based on the above prior art, in view of the occurrence of an accident due to a malfunction during work setting and the problem that the work is difficult to set, and the board installed on the upper surface of the bolster of the press machine, A fixed mold installed in a front part, a movable mold installed so as to be able to advance and retreat in the front-rear direction behind the fixed mold on the upper surface of the substrate, a pressing plate fixed directly under a slide of a press machine, and the movable plate in the substrate A first link having a lower end pivotally attached to the rear of the mold; a second link having a lower end pivotally attached to a rear end surface of the movable mold; and the pressing plate having an upper end attached to the first and second links. And a bearing portion that is slidable in the front-rear direction on the lower surface of the press machine, and by converting the vertical movement of the slide in the press machine into a horizontal direction and sliding the movable mold, Doyori By fixed in front is installed, and enables setting the workpiece without putting a hand below the slide, to solve the above problems.

要するに本発明は、プレス機におけるボルスタと昇降自在なスライドとの間に配置する金型であって、前記ボルスタの上面に設置する基板と、該基板の上面における前記スライドより手前の部位に設置する固定型と、前記基板の上面における固定型より後方に前後方向に進退可能に設置した可動型とを有しているので、スライドより手前に設置された固定型にワークをセットすることが出来るため、ワークセット時における誤作動によりスライドが下動しても手が挟まれる危険性を抑止することが出来、且つワークのセット作業を簡易化を図ることが出来る。
前記スライドの直下に固定した押圧板と、前記基板における前記可動型より後方に下端部を軸着した第１リンクと、前記可動型の後端面に下端部を軸着した第２リンクと、前記第１、２リンクの上端部を軸着した、前記押圧板の下面に前後方向にスライド可能に設けた軸受部とを有しているので、スライドの上下運動を水平方向に変換し、且つ可動型のスライド量がスライドのストローク量より長くすることが出来るため、プレス機自体のスライドのストローク量を短くしても対応することが出来、既存のプレス機にも設置出来る。 In short, the present invention is a mold that is arranged between a bolster and a slide that can be raised and lowered in a press machine, and is installed on a substrate that is installed on the upper surface of the bolster, and on a portion of the upper surface of the substrate that is in front of the slide. Since it has a fixed mold and a movable mold that can be moved back and forth in the front-rear direction behind the fixed mold on the upper surface of the substrate, the work can be set on the fixed mold installed in front of the slide In addition, it is possible to suppress the risk of a hand being caught even if the slide is moved down due to a malfunction during the work setting, and the work setting work can be simplified.
A pressing plate fixed immediately below the slide; a first link having a lower end pivotally attached to the rear side of the movable mold in the substrate; a second link having a lower end pivotally attached to a rear end face of the movable mold; Since it has a bearing part that is slidably mounted in the front-rear direction on the lower surface of the pressing plate, the upper end part of the first and second links are pivotally attached, so that the vertical movement of the slide is converted into a horizontal direction and is movable. Since the slide amount of the mold can be made longer than the stroke amount of the slide, it can be handled even if the slide stroke amount of the press machine itself is shortened and can be installed in an existing press machine.

前記基板の両側部上面にガイドシャフトを垂直に立設し、前記押圧板の両側部位で前記スライドからの突出部位に、前記ガイドシャフトの挿通部位を縦貫形成したので、押圧板を円滑に上下動させることが出来るため、第１、２リンクを介して可動型を円滑に進退させることが出来る等その実用的効果甚だ大である。   Since the guide shaft is vertically erected on the upper surface of both sides of the substrate, and the insertion portion of the guide shaft is vertically formed in the protruding portion from the slide at both side portions of the pressing plate, the pressing plate is smoothly moved up and down. Since the movable type can be smoothly advanced and retracted via the first and second links, its practical effect is significant.
