Abstract

The embodiment of the invention provides a stamped part rebound optimization method, which comprises the following steps of establishing a simulation model according to the attributes of a plate for producing a target part and the attributes of a mold for producing the target part; carrying out simulation and continuously adjusting process parameters to enable a simulation result to meet a presetrequirement, and obtaining a target process parameter corresponding to the minimum first rebound value; if the first rebound value is larger than a rebound threshold value, continuing simulation simulation on the basis of the target process parameters, continuously adjusting mold parameters, so that a simulation result meets a preset requirement, and a target mold parameter corresponding to a minimum second rebound value is obtained; and manufacturing the target part according to the target process parameters and the target mold parameters. The method solves the problems that in the prior art,the optimal parameters of rebound optimization are difficult to find, and rebound of a stamping part is difficult to restrain.

Description

technical field [0001] The invention relates to the technical field of stamping and forming, in particular to a springback optimization method of a stamping part. Background technique [0002] With the widespread application of high-strength steel in automobile bodies, the springback of high-strength steel parts has also received more and more attention. High-strength steels are relatively high in strength and are prone to springback during forming. At the same time, the size of most automobile panels is large, and the phenomenon of springback aggregation at the corners after stamping springback leads to large deviations in the size of the parts. When the springback is severe, it will affect subsequent installation and other processes. [0003] In addition, in order to achieve light weight, aluminum alloys are also used in stamping and forming. The elastic modulus of aluminum alloys is smaller than that of steel, and the rebound caused by residual stress is obvious. Spring...
