[0057] The swing rod 43 is arc-shaped, and one end of the swing rod 43 away from the pusher block 45 is in contact with the middle of the outer side of the clamping plate 34, so that the swing rod 43 is pushed by the clamping plate 34. The torque spring 44 is conical.

[0058] The third embodiment, as Figure 1-Figure 5 and Figure 8-Figure 9 As shown, based on the first embodiment:

[0059] A material receiving assembly 5 is installed in the middle of the bottom of the inner cavity of the frame 1, and the material receiving assembly 5 includes a U-shaped limit frame 51 and a material receiving frame 52. The U-shaped limit frame 51 is fixedly installed at the side of the bottom of the inner cavity of the frame 1, and the material receiving frame 52 is placed at the bottom of the inner cavity of the frame 1 and close to the U-shaped limit frame 51.

As the two symmetrical clamping plates 34 face each other, By moving, the right-angle lever 35 can be driven to move together, and the bottom end of the right-angle lever 35 is in contact with the connecting rod 572. As the right-angle lever 35 continues to move, the connecting rod 572 is pushed inward, so that the guide plate 571 can be pushed toward the inner position of the debris bin 56, and the reset spring 574 is compressed, so that the guide plates 571 on both sides that are symmetrical can be moved together, and the guide plates 571 can be installed at an angle to guide the debris dropped by the punching holes to the debris bin 56, so that the debris can be collected in a centralized manner.

[0062] The guide plate 571 is installed obliquely, and the plane plate 573 is installed obliquely. The position of the plane plate 573 corresponds to the position of the strip hole 575. When the clamping plate 34 moves outward, the right-angle lever 35 is driven to move together, and the pushing force of the connecting rod 572 by the right-angle lever 35 disappears. Under the elastic force provided by the reset spring 574, the guide plate 571 moves away from the inside of the debris bin 56.

[0063] At the same time, the flat plate 573 will move together with the guide plate 571, so that the flat plate 573 can be moved out from the position of the strip hole 575, so that the flat plate 573 is directly above the material bin 55, and by using the flat plate 573 to be installed at an angle, the automobile door lock accessories pushed away by the pushing block 45 can be guided through the flat plate 573, so that the automobile door lock accessories fall into the material bin 55.

[0069] In combination with the end of the swing rod 43 away from the push block 45 being fitted with the middle of the outer side of the clamping plate 34, the end of the swing rod 43 is pushed by the clamping plate 34, and under the rotation support of the cylinder 42, the push block 45 is driven to rotate and adjust the angle, and the torque spring 44 is elastically deformed by the torque force, so that the punched automobile door lock parts can be pushed by the moving push block 45 to unload, thereby completing automatic unloading;

[0070] When the clamping plate 34 moves outward, the right-angle lever 35 is driven to move together, and the pushing force of the connecting rod 572 by the right-angle lever 35 disappears, and under the elastic force provided by the reset spring 574, the guide plate 571 moves away from the inside of the debris bin 56;

[0071] At the same time, the flat plate 573 will move together with the guide plate 571, so that the flat plate 573 can be moved out of the position of the strip hole 575, so that the flat plate 573 is directly above the material bin 55, and the flat plate 573 is installed in an inclined manner, so that the automobile door lock parts pushed away by the pushing block 45 can be guided through the flat plate 573, so that the automobile door lock parts fall into the material bin 55, and the automobile door lock parts are collected;

[0072] As the clamping plate 34 clamps the next automobile door lock accessory blank, the driving force on the swing rod 43 disappears, and under the torque elastic force of the torque spring 44, the swing rod 43 drives the push block 45 to rotate in the opposite direction for reset, so that the push block 45 is away from the middle of the top of the frame 1, which is convenient for the subsequent punching work.
