One-piece forming die with multiple functions

Abstract

The invention relates to a one-piece forming die with multiple functions, in particular to one-piece forming cup die for use in fields of blanking, stretching, raising, lettering, flanging and the like. In the technical scheme, the one-piece forming die with multiple functions comprises an upper die plate and a lower die plate, wherein a guide sleeve is fixed to the edge part of the upper die plate; a stretching male die is fixedly arranged on the middle part of the lower surface of the upper die plate; a punching block is arranged inside the bottom end part of the stretching male die; a flanging female die insert is sleeved outside the stretching male die; a blanking flanging female and male die is sleeved outside the flanging female die insert; an upper fixed plate is sleeved outside the blanking flanging female and male die; a punching rod is arranged in the stretching male die and the upper die plate in a sliding mode; and the bottom end part of the punching rod is connected with the punching block. By the one-piece forming die, products can be formed in one piece, so that the yield and quality of the products can be improved.

Description

technical field [0001] The invention relates to a one-time forming mold with multiple functions, especially a one-time forming cup mold which can be used in various occasions such as blanking, stretching, embossing, lettering, flanging and the like. Background technique [0002] At present, the production of cups needs to go through six steps of blanking, stretching, embossing, lettering, trimming and flanging. Such a process requires a lot of equipment and labor, and due to the variety of processes, each process has a certain error, so the cumulative error of the product is relatively large, and the size of the final product is unstable. And it is necessary to carry out a trimming process before flanging, which wastes materials. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a multi-functional one-time forming mold that can make products one-time molded, improve product yield and quali...
