detailed description

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

Referring to Figures 1 and 2, an improved multi-punch stamping die includes an upper mold base 1, a lower mold base 16 and a guide rod 5 connecting the upper and lower mold bases, the upper surface of the lower mold base is provided with a concave Die 14, the lower surface of the upper die holder is provided with a punch 3, the lower surface of the punch 3 is provided with a number of punches 2, the punches 2 can be set to at least 3, and each punch 2 can be set to the same or different sizes. There may be at least three stamping grooves 12 on the upper surface of the lower backing plate 13 that are matched with the punch 2 . A lower backing plate 13 is provided in the cavity surrounded by the punching slit 17 of the die 14, and a return spring 15 is provided at the bottom of the lower backing plate 13, and the lower backing plate 13 floats up and down in the cavity. The upper surface of the lower backing plate 13 is provided with a plurality of stamping grooves 12 which are matched with the punch 2. The upper surface of one side of the lower mold base 16 is provided with an automatic unloading device.

The bottom of the stamping groove 12 and the two side walls are laid with a rubber layer 19 and a steel ball layer 20 sequentially from top to bottom, so that when the punch 2 exerts pressure on the stamping groove 12, the elastic buffer force of the rubber layer 19, and then The cushioning force generated by the relative movement between adjacent steel balls when pressed can effectively relieve the force of the stamping groove, thereby reducing the loss. The setting of the rubber layer 19 also protects the surface of the stamping workpiece from being scratched. In addition to improving the service life of the stamping die, it also improves the quality of the product.

The automatic unloading device includes a lifting seat 11, a telescopic cylinder 9, a telescopic arm 7, a suction plate 4, an induction device 8 and an air suction system (not shown in the figure), and one end of the lifting seat 11 is fixedly arranged on the lower mold The upper surface of the seat 16, the other end of the lifting seat is connected to the telescopic arm 7 through the support rod 10, one end of the telescopic arm 7 is connected to the telescopic cylinder 9, and the other end of the telescopic arm 7 is connected to the suction plate 4 , The suction plate 4 is provided with an air hole, and the air hole is connected with the suction system; the lifting seat 11 is provided with an induction device 8 . A loading box 6 is arranged between the automatic unloading device and the die 16 . The lifting seat 11 can be adjusted up and down according to the height of the lower backing plate 13 . During the actual stamping operation, when the punch 3 completes the stamping and rising, the induction device 8 sends a command to the telescopic cylinder 9, and the telescopic cylinder 9 drives the suction plate 4 of the telescopic arm 7 to move to the top of the lower backing plate 13, through the suction system The suction makes the suction cup suck the stamped workpiece in the stamping groove 12, and then the telescopic cylinder 9 drives the telescopic arm 7 to drive the suction disk 4 to shrink to the top of the loading box 6, the suction system exhausts, and the suction disk 4 loosens. With the adsorption effect on the workpiece, the workpiece naturally falls to the loading box 6 to complete a blanking process.

Above in conjunction with accompanying drawing, the embodiment of the present utility model has been described in detail, but the present utility model is not limited to above-mentioned embodiment, can also make various changes to it, these changes and improvements all fall within the scope of the claimed utility model.
