摘要:
针对铝合金汽车覆盖件拉延成形时易出现开裂、起皱等问题,以某品牌汽车铝合金侧围为例,对制件的工艺性进行了分析,设计了工艺补充面,并进行了初始模拟与分析。主要研究了门洞开裂的优化方案,提出了内圈拉延筋锁紧、优化坯料线R角、降低冲压速度3种方案,研究了其对门洞开裂的影响。模拟结果表明:锁紧内圈拉延筋,门洞处切向撕裂现象缓解,但板件内部出现开裂,此方案不可行;门洞开裂与坯料线R角有很大关系,钝化坯料线R角能有效解决门洞开裂问题;通过降低冲压速度,能对门洞应力集中区域起到辅助优化的作用。实际制件与仿真结果基本一致,对同类产品具有很好的参考意义。
For the problems of cracking and wrinkling in the drawing process of automobile panel for aluminum alloy, taking the aluminum alloy side frame of a brand automobile as an example, the manufacturability of part was analyzed, the addendum surface was designed, and the initial simulation and analysis were conducted. Then, the optimization schemes of cracking for door hole were mainly studied. The three schemes such as locking inner drawbead, optimization of R angle for blank line and reduction of stamping speed were proposed, and the influences of them on the cracking of door hole were researched. The simulation results show that the tangential cracking phenomenon at the door hole reduces by locking inner drawbead, but cracks appear in the panel, so this scheme is not feasible. However, the cracking of door hole has a great relationship with the R angle of blank line, and the passivation of R angle for blank line solves the problem of door hole cracking well. Furthermore, decreasing the stamping speed plays a role of auxiliary optimization in the stress concentration area of door hole, and the actual product is basically the same with the simulation results to have a good reference significance for the same kind of products.
