针对成形加强筋时产生起皱、翘曲、缩颈、裂纹的缺陷,进行成形加强筋的工艺分析计算,并在实际生产中进行试冲调试,经过批量生产后,总结了不同厚度、不同材料成形加强筋的最佳工艺参数。成形加强筋后,在零件不产生缩颈、裂纹的前提下,加强筋的高度h达到最大值,解决了提高零件刚度与产生裂纹的矛盾。利用成形设备油压机气垫力能够滞后于主缸压力的功能,改进模具结构,在模具结构上采用设备主缸压力压料、气垫反顶成形加强筋的新思路,解决了零件起皱、翘曲的缺陷,大大减少了校平的工作量,取得了较好的效果。
For the formation of stiffeners wrinkling, warping, necking, crack defects, the process of forming stiffeners analysis and test in the actual production of test-red debugging, after mass production, summed up the different thickness, different materials Forming the best technical parameters of stiffeners. After forming the stiffener, the height h of the stiffener reaches the maximum under the premise that the part does not produce constriction and crack, which solves the contradiction between increasing the rigidity of the part and generating the crack. The use of forming equipment hydraulic machine air cushion force can lag behind the function of the master cylinder pressure to improve the die structure, the die structure using master cylinder pressure die material, air cushion anti-top forming stiffener new ideas to solve the parts wrinkling, warping Defects, greatly reducing the level of the workload, and achieved good results.
