Stamping die shape conforming method

Abstract

The invention aims to provide a stamping die shape conforming method. The stamping die shape conforming method comprises the steps: A, an initial die is truly measured through CAE software, and a forming process initial die grid face and a subsequent process initial die grid face are obtained; B, based on plate performance parameters, the elastic scale factor after workpiece forming is measured and calculated, and a forming process scale die grid face is obtained; C, a non-working area in a subsequent process initial die model is deleted, and a subsequent process deletion die grid face is obtained; D, the forming process scale die grid face and the subsequent process deletion die grid face are subjected to simulation rebounding, and a rebounding grid face is obtained; E, the rebounding grid face and the subsequent process initial die grid face are fit through GOM software, and to-be-corrected deviation points and a deviation area are obtained; and F, all the to-be-corrected deviation points in the subsequent process deletion die grid face are adjusted, and shape conforming operation is completed. The stamping die shape conforming method overcomes defects in the prior art and has the characteristics of being simple in step, high in efficiency and good in shape conforming effect.

Description

technical field [0001] The invention relates to the field of stamping mold manufacturing, in particular to a stamping mold conformation method. Background technique [0002] The step of stamping the shape of the workpiece plays an important role in the springback stability and production stability of the mold, especially in the processing of thick plates and high-strength plates. The existing mold conformation method is as follows: firstly make the initial mold, stamp to obtain the workpiece, obtain the springback data of the workpiece through scanning and other methods, reversely establish the mold digital model, and then repair welding and reprocessing according to the mold digital model and other ways to perform conformal operation on the initial mold; this solution is time-consuming and costly, which greatly improves the production cycle of the mold. Contents of the invention [0003] The present invention aims to provide a stamping die conformation method, which over...
