The bottom of the connecting strip 632 is located in the inside of the movable groove 542.

[0058] The number of mounting blocks 634 and spring fives 635 is two, and the two mounting blocks 634 are respectively installed on both sides of the connecting strip 632. The bottom ends of the two spring fives 635 are respectively installed on the top of the mounting block 634, and the top ends of the two spring fives 635 are respectively installed on the bottom of the guide rail 621.

[0059] The movable plate 521 can push the wedge block 631 to move downward during the downward movement of the movable plate 521. At this time, the wedge block 631 pushes the two sliding bars 622 to move close to each other through the inclined groove 623, and the sliding bar 622 drives the two clamping plates 614 to move close to each other through the vertical plate 613. When the bottom of the movable plate 521 contacts the top of the guide rail 621, the two clamping plates 614 clamp the stamped workpiece.

[0060] During the downward movement of the wedge block 631, the connecting strip 632 moves downward synchronously with the wedge block 631. At this time, the connecting strip 632 pushes the insertion block 545 into the sliding groove 543, and the spring three 544 is compressed. When the insertion slot 633 on the connecting strip 632 corresponds to the insertion block 545, the insertion block 545 enters the insertion slot 633 to lock the wedge block 631, so that the stamping block 24 can be separated from the workpiece when the stamping block 24 moves upward.

[0061] As shown in Figures 1 to 4 and Figure 11As shown, the buffering mechanism 40 comprises a mounting plate 41 and a buffering assembly 42. The mounting plate 41 is mounted on the top of the mounting table 31, and the lower module 51 is mounted on the top of the mounting plate 41, and the mounting plate 41 is provided with a groove communicated with the waste groove 32. The buffering assembly 42 is four in number, and the bottoms of the four buffering assemblies 42 are respectively mounted at the four corners of the top of the mounting plate 41, and the tops of the four buffering assemblies 42 are respectively mounted at the four corners of the bottom of the connecting seat 21.

[0062] As shown in Figure 2 and Figure 11 As shown, the buffering assembly 42 comprises a vertical rod 421, a spring 422, a mounting ring 423 and a connecting cylinder 424. The bottom end of the vertical rod 421 is mounted on the top of the mounting plate 41, the spring 422 is sleeved on the outside of the vertical rod 421, the bottom end of the connecting cylinder 424 is slidingly connected on the outside of the top end of the vertical rod 421, and the top end of the connecting cylinder 424 is mounted on the bottom of the connecting seat 21. The mounting ring 423 is mounted on the outside of the bottom end of the connecting cylinder 424, and the spring 422 is mounted between the mounting plate 41 and the mounting ring 423 to buffer when stamping the workpiece.

[0063] Working principle: when stamping the workpiece, the plate is placed on the lower module 51 and is intermittently conveyed to the collecting seat 35 by the external conveying mechanism. In the process of conveying the plate, the stamping machine 12 drives the stamping block 24 and the stamping column 25 on the upper module 23 to move downward through the mounting seat 13. At this time, the stamping column 25 first punches a hole on the plate, and with the continuous downward movement of the upper module 23, the workpiece is punched out of the plate through the stamping block 24.

[0064] The upper module 23 drives the sliding rod 26 to move downward synchronously in the process of moving downward, and when the stamping column 25 passes through the movable plate 521, the sliding rod 26 drives the limiting block 533 to move out of the limiting groove 525 through the sliding plate 531 on the connecting rod 534, and at the same time, the sliding plate 531 drives the connecting plate 541 to move synchronously, so that the plug block 545 is located directly below the insertion groove 633. With the continuous downward movement of the upper module 23, the upper module 23 drives the stamping block 24 to stamp the plate to punch out the workpiece.

[0065] With the continuous downward movement of the stamping block 24, the stamping block 24 drives the movable plate 521 to push the wedge block 631 to move downward, and at this time, the wedge block 631 pushes the two sliding strips 622 to move close to each other to drive the two clamping plates 614 to move close to each other. When the bottom of the movable plate 521 contacts the top of the guide rail 621, the two clamping plates 614 clamp the stamped workpiece. When the wedge block 631 moves to the limit position, the plug block 545 enters the insertion groove 633 to lock the wedge block 631.

[0066] When the upper module 23 moves up, the stamping block 24 can be separated from the workpiece due to the clamping of the two clamping plates 614. As the upper module 23 continues to move up, the upper module 23 drives the sliding rod 26 to move up, so that the sliding rod 26 is separated from the connecting rod 534. At this time, the spring 532 drives the limiting block 533, the connecting rod 534 and the connecting plate 541 through the sliding plate 531 to reset, so that the plug block 545 moves out of the plug slot 633 to release the limiting of the connecting strip 632.

[0067] After the limiting of the connecting strip 632 is released, the wedge block 631 is driven to move up by the spring 635, so that the clamping plate 614 can be reset to release the clamping of the workpiece. As the sliding rod 26 continues to move up, the sliding rod 26 drives the movable plate 521 to move up through the connecting block 27 to push the workpiece on the baffle plate 522 to move up. In the process of moving up, the top of the movable plate 521 is in contact with the bottom of the limiting block 533 to push the limiting block 533 into the accommodating groove 56 again. When the sliding rod 26 moves to the limit position, the limiting block 533 enters the limiting groove 525 to limit the movable plate 521 again. At the same time, the baffle plate 522 pushes the stamped workpiece into the groove after the plate material is stamped.

[0068] At this time, with the movement of the plate material, the stamped workpiece can be moved to the collecting seat 35. When the plate material is stamped again, the upper module 23 drives the pressing rod 29 to move down through the fixed plate 28 to push the workpiece in the plate material out and fall into the collecting seat 35 to be stacked.

Those skilled in the art can make changes, modifications, replacements and variations to the above-described embodiments within the scope of the present application.
