全载体车身结构件级进冲压成形排样设计

Layout Design of Progressive Stamping Forming forFull Carrier Body Structural Parts

为复杂构形的车身结构件级进冲压成形排样设计提供参考,以全载体形式车身结构件为例,首先提出排样存在的主要设计问题,明确了设计任务;然后分析了制件的级进冲压成形工艺,设计了制件的排样图;最后通过实冲试验验证了排样工艺的合理性。试验所获产品零件无开裂、起皱等成形性问题,且关键成形部位达到了零件图的形位精度设计要求。

In order to provide a reference for layout design of progressive stamping forming of complex body structural parts,the main problems existing in layout designingare put forward and the design tasks are defined with the example of the full carrier body structure.Then the progressive stamping process of the partsis analyzed and the layout of the partsis designed.Finally,the rationality of the layout process is verified by the actual punching test.There are no forming problems such as cracking and wrinkling,and the key forming parts meet the shape and position precision design requirements of the part drawing.The results show that the layout design for full carrier is reasonable,and its process has practical reference value.
