Stamping method and special mold for serialized porous and complex plug-in metal parts

Abstract

The invention provides a stamping method for serialized porous and complex metal parts, which is characterized in that: the specific steps of the method are as follows: (1), take the base material of the metal part, and then place the base material of the metal part in a first-stage punch to disperse Disperse punching and positioning holes are carried out under the punching die of the hole; (2), move the metal parts after the dispersed punching to the secondary punching and trimming die module, punch the remaining holes, and punch down at the same time Two groups of corresponding sides without arc-shaped cuts and cut sides with arc-shaped cuts in the strip feeding direction; (3) Bending the two symmetrical sides without arc-shaped cuts after punching; ( 4), punching the opposite side with arc-shaped incision; (5), bending the side with arc-shaped incision after punching and the side opposite to it; (6), cutting off the connecting part of the part and the strip; the present invention The adaptability of the mold is increased, thereby improving the production efficiency and prolonging the life of the mold.

Description

technical field [0001] The invention relates to the technical field of stamping dies for a series of porous and complex plug-in metal parts in electronic products, in particular to a high-precision modular progressive die integrating punching and bending. Background technique [0002] At present, for a class of serialized porous and complex plug-in metal parts in electronic products, three methods can be used traditionally: (1) Multiple sets of single-process dies punch out multiple holes, and then use a pair of single-process dies to shape the product. (2) According to the shape characteristics of the product, multiple sets of composite molds are used for step-by-step forming. (3) Using a multi-station progressive die, first punch out positioning holes and multiple holes, then partially blank, then form, and finally cut off to process the product. [0003] In the above (1) and (2) processes, the main disadvantages are: after the transfer of multiple molds, the consistency ...

Problems solved by technology

[0004] Purpose of the invention: The present invention provides a stamping method and a special die for serialized porous complex metal parts. The accuracy is difficult to guarantee, the process is long, the efficiency is low, the cost is high, and it is easy to cause stress concentration in some parts of the part, which will affect the precision of the part and the problem of low mold life.
