摘要:
为了研究拼焊板在成形过程中存在的回弹问题,提高零件的成形质量,对某轿车激光拼焊板车门内板进行了冲压成形及回弹的研究,预测了在成形过程中可能出现的缺陷,通过设置拉深筋和调整压边力进行了工艺优化。在成形效果满意的情况下,对车门内板进行回弹分析,再根据回弹结果对模具进行整体回弹补偿,运用补偿后的模具重新进行成形和回弹的数值模拟,研究结果表明:通过补偿,横向厚板最大位移由原来的 14. 439 mm 减小到 0. 493 mm;横向薄板最大位移由原来的 7. 237 mm 减小到 3. 941 mm;纵向有法兰侧最大位移由 4. 360 mm 减小到 2. 199 mm;纵向没有法兰侧最大位移由 3. 490 mm 减小到 1. 132 mm,由此可知,经过模具型面补偿成形的零件回弹后与标准零件型面更加接近,运用这种方法能有效地减少回弹对零件装配精度的影响,得到高质量的车门内板覆盖件。
Abstract:
In order to study the problem of tailor welded blanks (TWBs) springback in the forming process and improve its forming quality,a study on the laser TWBs of car door inner panel was made,which was about punch forming and springback. Besides,its possible defects were predicted in the forming process,then the process optimization was conducted by setting the draw bead and adjusting the pressure-pad-force. In the case of satisfied forming results,the car door inner panel was made springback analysis. Then based on this rebound results,the pattern die was carried out overall springback compensation,and the numerical simulation of forming and springback was proceeded again by using that compensated pattern die. The results showed that,through the compensation,the maximum displacement of transverse thick plate is reduced form 14. 439 mm to 0. 493 mm,and that transverse sheet is reduced form 7. 237 mm to 3. 941 mm; the maximum displacement of its longitudinal direction with flange side is reduced form 4. 360 mm to 2. 199 mm,and that without flange side is reduced from 3. 490 mm to 1. 132 mm. Therefore,after inevitable springback,the parts with surface compensation formed by the compensated pattern die are closer to standard parts than others. Furthermore,using this method,it is effective to reduce the springback influence about parts assembling accuracy,with obtaining a high quality car door inner panel cover.
