次に、発明にかかる実施の形態のパンチプレス機1の金型交換動作について説明する。 <Operation>
Next, the die exchange operation of the punch press machine 1 according to the embodiment of the invention will be described.
金型の交換指示によって金型搬送部16が所望の金型17が載置されている位置に移動する。この際、把持部83の位置がモータ92によってX方向に移動し、モータ103によってY方向に移動する。モータ92(図13参照)およびモータ103を制御することによって、主面21aに平面上に収納された所望の金型17に正対した位置に把持部83を移動することができる。
The mold transfer unit 16 moves to the position where the desired mold 17 is placed according to the mold replacement instruction. At this time, the position of the grip portion 83 is moved in the X direction by the motor 92, and is moved in the Y direction by the motor 103. By controlling the motor 92 (see FIG. 13) and the motor 103, the grip portion 83 can be moved to a position facing the desired mold 17 housed on the main surface 21a on a plane.
次に、モータ105を駆動することによって、把持部83の把持機構121、122のうちいずれかの把持機構がフレーム部材21に向かってZ1方向に沿って移動する。図16は、把持機構121が金型17を把持している状態を示す図である。
Next, by driving the motor 105, one of the gripping mechanisms 121 and 122 of the gripping portion 83 moves toward the frame member 21 along the Z1 direction. FIG. 16 is a diagram showing a state in which the gripping mechanism 121 is gripping the mold 17.
把持機構121は、第1ハンド131、第2ハンド132および第3ハンド133が開いた状態で、パンチ41の把持リング53の両隣に一対の第1ハンド131が位置し、ストリッパ42の両隣に一対の第2ハンド132が位置し、ダイ43の両隣に一対の第3ハンド133が位置するまで、Z1方向に移動する。
In the gripping mechanism 121, with the first hand 131, the second hand 132, and the third hand 133 open, a pair of first hands 131 are located on both sides of the grip ring 53 of the punch 41, and a pair of first hands 131 are located on both sides of the stripper 42. Moves in the Z1 direction until the second hand 132 of the above is located and a pair of third hands 133 are located on both sides of the die 43.
そして、シリンダ134によって第1ハンド131、第2ハンド132および第3ハンド133が閉じられ、一対の第1ハンド131がパンチ41の把持リング53の把持溝53aに嵌り、更に爪131aが切り込み53bに嵌まる。また、一対の第2ハンド132がストリッパ42の把持溝42aに嵌り、更に爪132aが切り込み42bに嵌まる。また、一対の第3ハンド133がダイ43の把持溝43aに嵌り、更に爪133aが切り込み43bに嵌まる。
Then, the first hand 131, the second hand 132, and the third hand 133 are closed by the cylinder 134, the pair of first hands 131 is fitted into the grip groove 53a of the grip ring 53 of the punch 41, and the claw 131a is further inserted into the notch 53b. It fits. Further, the pair of second hands 132 fits into the gripping groove 42a of the stripper 42, and the claw 132a fits into the notch 42b. Further, the pair of third hands 133 fits into the gripping groove 43a of the die 43, and the claw 133a fits into the notch 43b.
図17は、パンチ41の第1ハンド131による把持状態を示す模式平面図である。図17に示すように、パンチ41は保持部80のバネ部材80aによって第1板状部材71上に保持されているが、バネ部材80aの爪80bは、切り込み53bのうちフレーム部材21側寄りの縁を係止している。一方、第1ハンド131の爪131aは、切り込み53bのうちフレーム部材21とは反対側寄りの縁を係止する。このため、第1ハンド131の爪131aは、バネ部材80aの爪80bに干渉することなく、切り込み53bに嵌ることができる。
FIG. 17 is a schematic plan view showing a gripping state of the punch 41 by the first hand 131. As shown in FIG. 17, the punch 41 is held on the first plate-shaped member 71 by the spring member 80a of the holding portion 80, but the claw 80b of the spring member 80a is closer to the frame member 21 side of the notch 53b. The edge is locked. On the other hand, the claw 131a of the first hand 131 locks the edge of the notch 53b that is closer to the side opposite to the frame member 21. Therefore, the claw 131a of the first hand 131 can be fitted into the notch 53b without interfering with the claw 80b of the spring member 80a.
次に、金型17を把持した状態で、モータ105を駆動することによって把持部83をZ2方向に沿ってフレーム部材21から離間するように移動し、金型17が金型収納部15から取り出される。
Next, while the mold 17 is gripped, the grip portion 83 is moved so as to be separated from the frame member 21 along the Z2 direction by driving the motor 105, and the mold 17 is taken out from the mold storage portion 15. Is done.
その後、加工部14に正対するように把持部83が移動され、切換シリンダ124を駆動し、金型17を把持していない把持機構122を加工部14に正対させる。そして、把持機構122によって加工部14に装着されている金型17が、図7および図8に示すように取り外される。取り外す際には、金型収納部15から金型17を把持した場合と同様に、一対の第1ハンド131がパンチ41の把持リング53の把持溝53aに嵌り、爪131aが切り込み53bに嵌まる。また、一対の第2ハンド132がストリッパ42の把持溝42aに嵌り、爪132aが切り込み42bに嵌まる。また、一対の第3ハンド133がダイ43の把持溝43aに嵌り、爪133aが切り込み43bに嵌まる。これによって、金型17が把持機構122に把持される。このように把持した状態で、把持機構122がX2方向に移動されることによって、加工部14から金型17が取り外される。
After that, the gripping portion 83 is moved so as to face the machining portion 14, drives the switching cylinder 124, and causes the gripping mechanism 122 that does not grip the mold 17 to face the machining portion 14. Then, the mold 17 mounted on the processed portion 14 by the gripping mechanism 122 is removed as shown in FIGS. 7 and 8. When removing, the pair of first hands 131 fits into the gripping groove 53a of the gripping ring 53 of the punch 41, and the claw 131a fits into the notch 53b, as in the case where the mold 17 is gripped from the mold accommodating portion 15. .. Further, the pair of second hands 132 fits into the gripping groove 42a of the stripper 42, and the claw 132a fits into the notch 42b. Further, the pair of third hands 133 fits into the gripping groove 43a of the die 43, and the claw 133a fits into the notch 43b. As a result, the mold 17 is gripped by the gripping mechanism 122. In the gripped state in this way, the die 17 is removed from the machined portion 14 by moving the gripping mechanism 122 in the X2 direction.
次に、切換シリンダ124を駆動することによって、金型収納部15から取り出した金型17を把持する把持機構121が加工部14の正面に配置される。
Next, the gripping mechanism 121 that grips the mold 17 taken out from the mold storage portion 15 by driving the switching cylinder 124 is arranged in front of the processing portion 14.
そして、把持機構121が加工部14に向かってZ1方向に移動して加工部14に金型17が装着される。
Then, the gripping mechanism 121 moves toward the processed portion 14 in the Z1 direction, and the mold 17 is mounted on the processed portion 14.
次に、把持部83は加工部14からZ2方向に沿って離間した後、モータ92およびモータ103を駆動して、加工部14から取り外した金型17を金型収納部15の所定位置に収納する。
Next, the grip portion 83 is separated from the processing portion 14 along the Z2 direction, and then the motor 92 and the motor 103 are driven to store the mold 17 removed from the processing portion 14 at a predetermined position in the mold storage portion 15. To do.
収納する際には、加工部14から取り外した金型17を把持している把持機構122が載置位置に正対する位置に移動する。その後、各々の保持部80のバネ部材80aの爪80bが、切り込み53b、42b、43bに嵌る位置まで、把持機構122をフレーム部材21に向けてZ1方向に沿って移動する(図17参照)。そして、第1ハンド131、第2ハンド132および第3ハンド133を開くことによって、金型17が金型収納部15に載置される。
When storing, the gripping mechanism 122 that grips the mold 17 removed from the processing portion 14 moves to a position facing the mounting position. After that, the gripping mechanism 122 is moved toward the frame member 21 along the Z1 direction until the claw 80b of the spring member 80a of each holding portion 80 fits into the cuts 53b, 42b, 43b (see FIG. 17). Then, by opening the first hand 131, the second hand 132, and the third hand 133, the mold 17 is placed on the mold storage unit 15.
以上のように、加工部14と金型収納部15の間で金型17を金型搬送部16によって受け渡しすることができる。
As described above, the mold 17 can be delivered between the processing unit 14 and the mold storage unit 15 by the mold transport unit 16.
