］。The moving shafts 7a and 7b are supported by a support stand 9 via bearings 8, and a pair of tension springs lla and llb are provided between the support stand 9 and the other end of the workpiece receiving plate 6. There is. The workpiece receiving plate 6 can freely move in and out between the upper die 2 and the lower die 1, and is always given a tendency to retreat. Further, a double pulley 12 is rotatably supported on a support shaft 13 at a side portion of the ram 30. The double pulley 12 consists of a small pulley 2a and a large pulley 12b that are fixed together, and the end of the wire 4a wound around the small boob IJ12a is fixed to a pin 15 protruding from the ram 3. . In addition, the wire 4b wound around the large pulley 12bK is connected to the guide pulley 16.
It is fixedly attached to a member 7c installed on the rear side ends of both moving shafts 7a and 7b. ：：、・： Then double pulley □・12. ram 3 is required to rise].
倍率だけ拡大され、当該ラム３が上死点近傍の高さまで
上昇したとき、ワーク受板６は上型２および下型１間の
所定のワーク受位置まで前進する。When the ram 3 is increased by the magnification and raised to a height near the top dead center, the workpiece receiving plate 6 advances to a predetermined workpiece receiving position between the upper die 2 and the lower die 1.

19b and a belt 21. 22 is a work stopper made of an elastic material, and the workpiece 4 on the workpiece receiving plate 6 is
This is for dropping a onto the belt conveyor 17.
次に第４図も参照して作用を説明する。Next, the operation will be explained with reference to FIG.
ラム３の下降に伴なって上型２が下型１に向けて下降し

ｌｂの弾発力により退出位置にある。As the ram 3 descends, the upper die 2 descends toward the lower die 1, and the workpiece 4 is punched out between the upper die 2 and the lower die 1 to form a workpiece 4a of a predetermined shape. When the upper die 2 is lowered in this manner, the wire 14b wound on the thick boot +712b side is unwound and extended as shown in FIG.
It is in the exit position due to the elastic force of lb.
次いでラム３の上昇動作移行に伴なって、上型２が打抜

１との間に前進する。Next, as the ram 3 moves upward, the upper die 2 rises with the workpiece 4a attached and held by the biting during punching, and the wire 14a on the small boob IJ12a side is pulled back by the pin 15 and rewound 2. The heavy pulley 12 rotates as indicated by the arrow A in FIG. Due to this rotation, the wire 14b is wound on the large pulley 12b side, and the workpiece receiving plate 6 moves forward between the upper die 2 and the lower die 1 against the elastic force of the tension springs lla and llb. .
このときラム３の移動量に対するワーク受板６の移動量
は２重プーリ１２によシ所要倍率だけ拡大されてラム３
が上死点近傍の高さ位置まで上昇した時、ワーク受板６
は上型２の嫌ぼ直下位置まで移動する。At this time, the amount of movement of the workpiece receiving plate 6 relative to the amount of movement of the ram 3 is magnified by the required magnification by the double pulley 12,
When the workpiece receiving plate 6 rises to a height near the top dead center,
moves to a position directly below the top mold 2.
そして上型２が上死点近傍の高さ位置まで上昇するとノ
ックアウト装置が作動してワーク４ａが上型２から離脱
して落下し、ワーク受板６により受止められる。When the upper die 2 rises to a height near the top dead center, the knockout device is activated, and the workpiece 4a separates from the upper die 2 and falls, and is received by the workpiece receiving plate 6.
次にラム３が引続いての打抜き動作のために下降を始め

たままワーク４ａ上を滑り、上型２が打抜き位置まで降
下したときワーク４ａはワーク受板６に載置されたまま
第１図に示すような所定外部位置まで取り出される。Next, when the ram 3 begins to descend for the subsequent punching operation, the wire 14b on the large boob IJ 12b side is rewound as described above, and the work receiving plate 6 begins to retreat. During this exit, the work stopper 22 comes into contact with the edge of the work 4a placed on the work receiving plate 6, but the other end of the work 4a comes into contact with the non-slip 6a and is received. Therefore, the flexible work stopper 22 slides over the work 4a while being bent, and when the upper mold 2 descends to the punching position, the work 4a remains placed on the work receiving plate 6 as shown in FIG. It is taken out to a predetermined external position as shown in FIG.

出動作に備えられる。Next, when the ram 3 shifts to the upward movement again, the workpiece receiving plate 6 starts moving forward toward the space between the upper die 2 and the lower die 1 as described above. At this time, the work stopper 22 comes into contact with the edge of the work 4b on the opposite side from the time of leaving, and the work 4a falls onto the belt conveyor 17. The workpiece 4a is further transferred by the belt conveyor 17 and discharged to an appropriate external position. On the other hand, the workpiece receiving plate 6 on which the workpiece 4a has been dropped onto the belt conveyor 17 is moved as it is between the upper die 2 and the lower die 1, and is prepared for the subsequent discharge operation of the workpiece 4a.
なお上述の実施例ではピン１５をラム３の部分に突設さ

ができるという効果が得られる。As described in detail above, according to the present invention, the workpiece receiving plate is disposed between the upper die and the lower die so that it can freely move in and out and always has a tendency to withdraw, and after punching, it is held by the upper die and the workpiece is held in the upper die. Since the workpiece that is released from being held at a predetermined raised position of the upper die is received and discharged by the workpiece receiving plate that is advanced against the retreating tendency in relation to the rise of the upper die, the workpiece discharge mechanism is driven. Since a separate drive source and control device to be controlled are not required, and accurate operation timing can be obtained with a relatively simple configuration, the cost of the device can be reduced.
またワーク受板はワークを単に載置するだけなのでワー
クの材質の如何に拘らず、ワーク排出を確実になし得る
という効果が得られる。Furthermore, since the workpiece is simply placed on the workpiece receiving plate, the workpiece can be reliably ejected regardless of the material of the workpiece.
