[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-6 The utility model provides a technical solution: a metal parts stamping equipment, including a lower die base 10 and an upper die base 20 located directly above the lower die base 10, a lower clamping plate 11 and a buffer plate 12 are arranged on the upper surface of the lower die base 10 from bottom to top, a spring 15 is arranged between the buffer plate 12 and the lower clamping plate 11, a groove is provided at the center of the front side of the buffer plate 12, a receiving block 13 extending into the groove is provided on the upper surface of the lower clamping plate 11, the buffer plate 12 is slidably connected to the receiving block 13, and two symmetrical stamping holes 14 are arranged on the surface of the receiving block 13, by arranging the spring 15 between the buffer plate 12 and the lower clamping plate 11, the pressure on the buffer plate 12 is reduced, the vibration and scratches caused by the stamping of the buffering equipment can be reduced, and the wear of the equipment can be reduced.

[0025] Among them, a slider is provided on the buffer plate 12, and a sliding groove cooperating with the slider is opened on the surface of the receiving block 13. The buffer plate 12 and the receiving block 13 are slidably connected through the cooperation of the slider and the sliding groove. The purpose is to limit the slider on the buffer plate 12 and the sliding groove on the surface of the receiving block 13 to only be connected by sliding up and down, so as to ensure the stability of the stamping structure.

[0026] Among them, a feed hole 17 is opened through the position corresponding to the stamping hole 14 on the lower die base 10 and the lower clamping plate 11, and a collection box 70 for collecting stamping waste is slidably installed inside the lower die base 10. The collection box 70 is located below the feed hole 17. The upper surface inside the collection box 70 is a slope that is high on the outside and low on the inside. The slope inside the collection box 70 slides the fallen waste to the lowest point inside the collection box 70. Since the collection box 70 is transparent, it is convenient to observe the accumulated amount of metal material, and the collection box 70 can be cleaned in time.

[0027] Among them, two hydraulic cylinders 30 are provided between the upper surface of the lower die base 10 and the lower surface of the upper die base 20. The two hydraulic cylinders 30 are both on the side away from the lower clamping plate 11. The two hydraulic cylinders 30 are used to drive the pressing plate 22 to move downward, thereby achieving the compression and fixation of the metal belt 60 between the pressing plate 22 and the buffer plate 12.

[0028] Among them, the lower surface of the upper die base 20 is provided with an upper clamping plate 21 and a pressing plate 22 from top to bottom. The pressing plate 22 is located directly above the buffer plate 12 to ensure that the pressing plate 22 performs stamping movement on the metal strip 60 in the vertical direction to ensure uniform force and stable structure.

[0029] Among them, recesses are provided at the positions corresponding to the grooves of the upper clamping plate 21 and the pressing plate 22, and two symmetrical punching parts 40 are provided in the recesses. The punching parts 40 are located directly above the punching holes 14 to ensure the cooperation between the punching parts 40 and the punching holes 14, and the aperture of the punching holes 14 is much larger than the aperture of the punching parts 40, which is convenient for replacing the punching parts 40 with different apertures in the later stage.

[0030] Among them, the punching member 40 includes a fixed block 41 fixedly installed on the lower surface of the upper clamping plate 21, and a punch head 42 is threadedly installed on the end of the fixed block 41. The threaded punch head 42 is convenient for the later replacement of the punch head 42 and the replacement of the punch head 42 with different apertures.

[0031] Among them, a limit plate 16 is provided on the rear side of the upper surface of the buffer plate 12, and a limit groove 23 cooperating with the limit plate 16 is provided on the rear side of the lower surface of the pressing plate 22. The limit plate 16 is located directly below the limit groove 23. The limit plate 16 cooperates with the limit groove 23 so that one side surface of the metal belt 60 is close to the limit plate 16 and moves forward, ensuring the stable position of the metal belt 60.

[0032] Among them, a guide member 50 is provided on one side of the lower clamping plate 11, and the guide member 50 includes a frame and five transmission rollers 51 rotatably installed in the frame. The five transmission rollers 51 are connected by belts 53. A motor 52 is fixedly installed at one end of the outer side of the frame. The output end of the motor 52 is fixedly connected to the central axis of one of the transmission rollers 51. The motor 52 cooperates with the transmission roller 51 to allow the metal belt 60 to move forward automatically, ensuring that the metal belt 60 can move forward continuously after stamping. No manpower is required to move the metal belt 60 forward, which saves manpower and improves production efficiency.

[0033] Working principle: When in use, the guide member 50 is used to move the metal belt 60 forward to the buffer plate 12, and the hydraulic cylinder 30 is started to drive the pressing plate 22 to be pressed down until it contacts the metal belt 60. The pressing plate 22 continues to punch the metal belt 60 downward. A spring 15 is arranged between the buffer plate 12 and the lower clamping plate 11, and the slider on the buffer plate 12 cooperates with the slide groove on the surface of the receiving block 13 to slide up and down, so as to reduce the pressure on the buffer plate 12, thereby reducing the vibration and scratches caused by the stamping of the buffering equipment and reducing the wear of the equipment.

[0034] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
