[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-7This utility model provides a technical solution for a high-efficiency waste removal structure for composite metal stamping: a high-efficiency waste removal structure for composite metal stamping includes a base 1, a lower die base 2, a cutter 3, a material unloading groove 4, a workpiece 14, positioning pins 5, a nitrogen spring 6, an upper die base 7, a pressure base 8, a spring 9, a nitrogen spring 10, a top plate 11, a guide post 13, and a guide sleeve 12. Specifically, the positions of the two sets of positioning pins 5 and the product holes on the workpiece 14 correspond to each other, so that the workpiece 14 can be placed outside the two sets of positioning pins 5 and above the multiple sets of nitrogen springs 6, thereby guiding the placement of the workpiece 14.

[0038] An external lifting device drives the top plate 11, pressure seat 8 and upper mold seat 7 to move up and down. Multiple sets of guide pillars 13 slide inward within multiple sets of guide sleeves 12 to guide the movement of the pressure seat 8 and upper mold seat 7 and improve accuracy.

[0039] When the pressure seat 8 is lowered, it presses and fixes the workpiece 14 on the lower mold seat 2. At this time, nitrogen spring 16 and nitrogen spring 210 are both in the contracted state. The two sets of positioning pins 5 enter the pressure seat 8. After the pressure seat 8 and the lower mold seat 2 are separated, nitrogen spring 16 and nitrogen spring 210 push the workpiece 14 out of the pressure seat 8 and the lower mold seat 2 respectively, so as to achieve the anti-sticking effect.

[0040] When the upper die holder 7 moves downward, it punches the edge of the workpiece 14. At the same time, multiple sets of cutters 3 squeeze and cut the waste material, which breaks and falls into multiple sets of feeding grooves 4. Automatic feeding is achieved during punching, and no manual cleaning of waste material is required.

[0041] This composite hardware stamping high-efficiency waste removal structure, in actual use, first places the workpiece 14 outside the two sets of positioning pins 5, so that it is above the multiple sets of nitrogen springs 6. Then, the lifting device drives the top plate 11, pressure seat 8 and upper die seat 7 to move downward. The pressure seat 8 presses and fixes the workpiece 14 on the lower die seat 2, and the nitrogen springs 6 and 10 are both in the retracted state. The two sets of positioning pins 5 enter the pressure seat 8. Then, the lifting device drives the top plate 11 and upper die seat 7 to move downward again, so that the upper die seat 7 punches the edge of the workpiece 14. At the same time, the multiple sets of cutters 3 squeeze and cut the waste material, which breaks and falls into the multiple sets of discharge slots 4. After the punching and discharge are completed, the lifting device drives the top plate 11, pressure seat 8 and upper die seat 7 to move upward and reset. The nitrogen springs 6 and 10 push the workpiece 14 out of the pressure seat 8 and lower die seat 2 respectively, and the operator removes and replaces the workpiece 14.
