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

Embodiment 1

[0043] A method of eliminating a filament bumper front bumper front bumper, the specific steps are as follows:

[0044] A1, data measurement of the front bumper labeling area of ​​the wing plate stamping bumper by precision measurement equipment;

[0045] A2, data directionality is analyzed by comparing all type data in front of the front bumper on the front bumper.

[0046] A3, the correlation of each type is confirmed by analyzing the data directionality;

[0047] A4, the process supplementary surface in front bumper in front of the front bumper is compensated for the replacement of the front bumper back to the front bumper.

[0048] A5, the front bumper on the front bumper side of the bumper is removed after the reticle is removed after the retardation is confirmed and the front bumper label region of the front bumper front bumper is measured by precision measurement equipment;

[0049] A6, confirm the front bumper on the front bumper on the front bumper and the state of the bu...

Abstract

The invention discloses a method for eliminating the distortion in the overlapping area of ​​the front bumper of the stamped part of the fender, including the application of the forming compensation process, the development of the debugging process, and the like. This method uses precision measuring equipment to confirm the amount of frontal distortion and springback of the stamped parts of the fender; by supplementing the fillet compensation to the shaping process, and using the principle of stable plastic deformation of the fillet, the stamped part of the fender is effectively corrected Front protection twist and rebound; standardize the grinding direction of the symbol to ensure the stability of the front protection twist and rebound of the corrected fender stamping parts; the rational use of multi-dimensional installation point compensation means eliminates the front protection distortion and rebound of fender stamping parts Comprehensive debugging method. Effectively correct the front protection distortion and springback of the fender stamping parts, shorten the debugging cycle, improve the data stability, and ensure the overall assembly quality of the car body.

Description

Technical field [0001] The present invention relates to a front fender stampings optimized overlap region bumper distortion method for a vehicle body outer cover fender stampings lift assembly and vehicle appearance quality optimization data field. Background technique [0002] The industry before original fender stampings bumper assembly data debugability overlap region is the deviation of the data designer front fender stampings presence overlap region A bumper face and a contour modification modified, the modified wing data sub-assembly plate stamping and the outline profile qualified, but destroyed the standard state of the mold surface a, seriously affect the stability of the mold. The original data before the overlap region bumper fender stampings debugging method can optimize the relationship between the front fender panel mounting region stampings bumper overlap, can not completely eliminate the front bumper fender stampings twisted tape overlap region to the deviation of...
