Abstract

The invention provides a design method for a die molded surface and a panel die to solve the technical problem that in the prior art, the precompensation precision of the die molded surface is low. The design method for the die molded surface includes the following steps that firstly, the elastic deformation amount of the die under punching force is calculated; secondly, extracting and coupling of a grid node point cloud are calculated based on a die deformation finite element; and thirdly, the exquisite die surface is generated based on finite element calculation. The design method for the die molded surface is used for designing the panel die, and the precompensation precision of the die molded surface is improved.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to a method for designing a mold surface and a covering mold. Background technique [0002] When stamping the automobile panel mold, it is necessary to ensure that the precision of the stamped panel meets the design requirements and the quality is stable. Always be in uniform contact. Usually, the convex model surface and the concave model surface of the automobile panel mold are uniformly offset material thickness, but in the process of use, due to the existence of the forming force of the press, the mold will undergo uneven elastic deformation. As a result, the convex model surface and concave model surface of the mold and the sheet cannot be evenly contacted, which eventually leads to the problems of low precision and unstable quality of the workpiece. [0003] In order to solve the above problems, a fine die surface design technology based on finite element numerical simul...
