The design considers the usability of the inclined guide post and the safety of elastic deformation, has the advantages of both beauty and beauty, but consumes the elastic supporting part, and the cost is increased to a certain extent.

Further, in one embodiment, the guide post member has at least three angular positions, which is advantageous for securely positioning the object to be processed with a small number of guide post members, such as one guide post member, to prevent the object from moving. In one embodiment, the guide post comprises a first guide post and a second guide post, the positioning groove comprises a first positioning groove and a second positioning groove, and the guide post opening comprises a first guide post opening and a second guide post opening; the first positioning groove and the first guide post opening are used for being arranged corresponding to a first positioning part of an article to be processed, the first guide post piece is respectively arranged in the first positioning groove, the first guide post opening and the groove in a penetrating mode, and the first guide post piece is also used for being arranged in the first positioning part in a penetrating mode; the second positioning groove and the second guide post opening are used for being arranged corresponding to a second positioning part of the product to be processed, the second guide post piece is respectively arranged in the second positioning groove, the second guide post opening and the groove in a penetrating mode, and the second guide post piece is also used for being arranged in the second positioning part in a penetrating mode. In one embodiment, the first guide post member and the second guide post member are differently shaped. Such design is favorable to pinpointing pending article, die holder, splint, upper cover plate, cope match-plate pattern and lower bolster, ensures to get rid of the accuracy of cutting edge of a knife or a sword, does not produce the secondary bad.

In one embodiment, the flash punching die is further provided with a spring, one end of the spring is fixed on the upper die plate, and the other end of the spring is elastically connected with the clamping plate. The design is favorable for controlling the force application of the clamping plate, so that the clamping plate can be stably pressed on the to-be-processed product, and the problem that the to-be-processed product is deformed due to overlarge pressure is solved.

In one embodiment, as shown in fig. 15 and 16, two cuppers 500 simultaneously process two workpieces 200 to be processed fixed on the fixing base 100, the through slots 400 are regularly arranged in a row, the workpieces 200 to be processed are correspondingly arranged in a row, and a distance between the two through slots 400 is greater than a width of one cupper 500 for processing. Referring to fig. 17 and 18, the copper tool 500 is provided with a processing end 510, and the processing end 510 is used for matching the processing cavity arrangement of the workpiece 200 to be processed.
