Embodiment Construction

[0085] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.

[0086] The present invention solves the problem of the control accuracy of the stamping springback of the fender by proposing a theory of full-profile compensation for the fender, and designs an effective full-profile compensation method for the stamping springback based on this theory. Realize the control of the dimensional accuracy of the automobile fender.

[0087] The invention proposes that the theory of adopting the full profile compensation for the fender is based on the theoretical method of calculating the input based on the output of the function.

Abstract

The invention relates to the technical field of stamping die manufacturing, in particular to a stamping springback full-profile compensation method for an automobile fender. The stamping springback full-profile compensation method comprises the following steps: S1, obtaining a basic springback simulation result based on a forward function model; S2, obtaining a full-profile springback compensationstrategy based on a reverse function model; and S3, carrying out reconstruction optimization and simulation verification on the tool body of the compensation process based on a full-profile springback compensation strategy. According to the stamping springback full-profile compensation method for an automobile fender, the design efficiency and precision of fender springback compensation are improved, and the actual part size debugging period is shortened, and the realizability, reliability and accuracy of stamping springback compensation are achieved.

Description

technical field [0001] The invention relates to the technical field of stamping die manufacturing, and more specifically, relates to a full-profile compensation method for stamping springback of an automobile fender. Background technique [0002] The fender is an important part of the car. In the body structure, it needs to be matched with important parts such as the side wall, front door, front cover, front bumper, and headlights. Its dimensional accuracy has an important impact on the body assembly. [0003] The structure of the fender itself is complex, and the law of stamping springback is complex, which leads to the control of its manufacturing accuracy has always been a difficult problem. In order to solve this problem, springback compensation is usually performed based on the springback simulation in the process design stage. [0004] At present, the most commonly used springback compensation technology scheme is the local compensation method, that is, to keep a part...
