Method for eliminating distortion of lap joint area of fender stamping part front bumper

Abstract

The invention discloses a method for eliminating distortion of a lap joint area of a fender stamping part front bumper. The method comprises the following steps of application of a forming compensation process, development of a debugging process and the like. According to the method, precision measurement equipment is used in cooperation to confirm the fender stamping part front bumper torsion resilience value; by supplementing fillet compensation to a shaping process and utilizing the principle of fillet plastic deformation shaping stability, the fender stamping part front bumper torsion resilience is effectively corrected; the compliance grinding direction is standardized to ensure that the corrected fender stamping part front bumper torsion resilience is stable; and through reasonable use of a multi-dimensional installing point compensation means, the comprehensive debugging method for eliminating the fender stamping part front bumper torsion resilience effectively correct the fender stamping part front bumper torsion resilience, the debugging period is shortened, the data stability is improved, and the overall assembly quality of a vehicle body is guaranteed.

Description

Technical field[0001]The invention relates to a method for optimizing the distortion of the front bumper overlap area of ​​a fender stamping part, which is suitable for the field of upgrading the assembly data of the fender stamping part in the outer cover of an automobile body and optimizing the appearance quality of the whole vehicle.Background technique[0002]The industry’s original fender stamping parts front bumper overlap area assembly data improvement and debugging method is that designers modify the data deviation existing in the front bumper overlap area of ​​the fender stamping parts and modify the profile. The modified wing The assembly data of the profile and contour of the sub-board stamping parts are qualified, but the standard state of the mold A side is destroyed, which seriously affects the stability of mold production. The data debugging method of the front bumper overlap area of ​​the original fender stamping parts can only be to optimize the assembly relationship ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of overall assembly data of the vehicle body caused by the distortion of the front bumper lap area of ​​the stamped part of the fender, and provide a method for eliminating the distortion of the lap area of ​​the front bumper of the stamped part of the fender. The present invention Through the use of precision measuring equipment to confirm the distortion of the front bumper overlap area of ​​the fender stamping parts; through supplementing the fillet compensation to the shaping process, and using the principle of stable plastic deformation of the fillet, the fender stamping parts are effectively corrected The overlapping area of ​​the front bumper is distorted; standardize the grinding direction of the symbol shape to ensure the distortion and stability of the front bumper overlapping area of ​​the revised fender stamping parts; the reasonable use of multi-dimensional mounting point compensation means eliminates the front bumper of the fender stamping parts A Comprehensive Debugging Method for Distortion in Bar Lap Area
