Detailed ways

A preferred embodiment of the present utility model is described in detail below with reference to the accompanying drawings. However, the protection scope of the present invention is not limited to the following examples, that is, any simple equivalent changes and modifications made based on the scope of the patent application of the present invention and the contents of the description are still within the scope of the patent of the present invention.

Referring to Figures 1-2, it is a waste punching die according to the present utility model, comprising a blanking die upper plate 1, a blanking die lower plate 2 and a blanking bottom plate 3 arranged in sequence from top to bottom. The blanking bottom plate 3 is fixed on the lower template of the die-cutting machine table, and a positioning groove (marked in the figure) that is consistent with the blanking die lower plate 2 is formed on the upper side of the blanking bottom plate 3, and the blanking die lower plate 2 is placed. in the positioning groove and fixed with the blanking bottom plate 3 by adhesive tape. The upper plate 1 of the blanking die is fixed on the upper template of the die-cutting machine, and moves up and down together with the upper template of the die-cutting machine. The four corners of the upper plate 1 of the blanking die are provided with upper and lower die fixing pins 13, and the four corners of the lower plate 2 of the blanking die are correspondingly provided with upper and lower die fixing holes 22. When the upper plate 1 of the blanking die moves up and down together with the upper platen of the die-cutting machine, the four upper and lower die fixing pins 13 at the four corners of the upper plate 1 of the blanking die pass through the four corresponding four corners of the lower plate 2 of the blanking die. In the fixing holes 22 of the upper and lower molds, the precise alignment between the upper plate 1 of the blanking mold and the lower plate 2 of the blanking mold is realized.

The left and right sides of the lower side of the upper plate 1 of the blanking die form an etching die area 11 and a punching pin area 12 respectively. The etching die area 11 is provided with a number of knife dies 111 for punching and cutting the product to be processed. The needle area is provided with a number of scrap punching needles 121 for ejecting the products after punching and cutting, and the scrap punching needles 121 are flat-headed thimbles; One is set correspondingly and distributed in an array.

The lower plate 2 of the blanking die corresponds to the position of each waste punch 121 in the punching area 12 of the upper plate 1 of the blanking die. A waste blanking hole 21 is respectively provided, and the blanking bottom plate 3 corresponds to the punching needle of the upper plate 1 of the blanking die. The area 12 is provided with a blanking port 31 . That is, the blanking port is provided corresponding to the waste punching needle 121 and the waste blanking hole 21 .

The left and right sides of the lower plate 2 of the blanking die are also provided with feeding and conveying components, through which the product 4 to be processed is conveyed from one end of the upper side of the lower plate 2 of the blanking die to the other end.

When the scrap punching die is working, the product to be processed passes between the upper plate 1 of the blanking die and the lower plate 2 of the blanking die through the feeding conveying assembly, that is, it is conveyed from one end of the upper side of the lower plate 2 of the blanking die to the other end. When the product travels between the upper plate 1 of the blanking die and the lower plate 2 of the blanking die according to the set step distance, the product first enters the etching die area, and at this time the upper plate 1 of the blanking die moves to the upper platen of the die-cutting machine. The lower plate 2 of the blanking die is moved down and pressed down, and the die 111 of the etching die area 11 punches and completely cuts the product. Then, the upper plate 1 of the blanking die moves upward together with the upper die plate of the die-cutting machine, that is, it rises; at the same time, the feeding and conveying component drives the product to be pulled to the position corresponding to the punching area according to the set step distance. At this time, the blanking die is The upper plate 1 presses the lower plate 2 of the material die again with the upper platen of the die-cutting machine, and the waste punching needle 121 of the upper plate 1 of the blanking die punches the correspondingly punched and completely cut waste material, and pushes out the waste material. It falls into the blanking opening of the blanking bottom plate 3, and enters the waste collection box from the blanking opening. So far, a waste punching and ejecting process is completed, and such a cycle can realize continuous processing of products.

It can be seen from this that the scrap punching die is provided with the upper plate of the blanking die, the lower plate of the blanking die and the bottom plate of the blanking die in the die-cutting machine table, and the upper plate of the blanking die is provided with a knife for punching and cutting. The die and the scrap thimble that ejects the scrap, cooperate with the lower plate of the blanking die and the feeding conveying assembly to transport the product to one end of the lower plate of the blanking die and the other end. Ejection, so as to realize the automatic operation of punching and ejecting waste, which not only greatly improves the efficiency, saves manpower, but also ensures the product accuracy.
