摘要：

针对军车车架纵梁结构具有相似性、对称性以及多种改型方案的特点，设计开发了一种柔性化冲压模具。该模具共用一套凸凹模本体；凸凹模的直线段长度和宽度均可调，通过更换、移动或者翻转镶块即可实现多种直线段的变形方案；曲线段采用可翻转的镶块形式，通过更换、翻转镶块即可适应不同曲线段结构；最后，通过试制对所设计的模具方案进行验证。结果表明：该模具不仅能够实现同一车型左右纵梁的共模，而且能够实现同一平台车型车架多种改型设计的共模，与传统模具结构方案相比，采用柔性化冲压模具方案，成本和工装数量均缩减50%以上，开发周期缩短50%以上。

For the structure of military vehicle frame longitudinal beam having the characteristics of similarity, symmetry and various modification schemes, a flexible stamping die was designed, which shared a set of punch and die. The straight line segments of punch and die are adjustable along the length and width directions, a variety of change schemes for the straight line segments were achieved by replacing, moving or flipping inserts. And the curve segments adopted reversible inserts to meet different structures of curve segments by replacing and flipping inserts. Finally, the design scheme of die was verified by the trial production. The result shows that not only the right and left frame longitudinal beams for the same type of vehicle, but also various modification schemes of vehicle frame based on the same platform can be realized by a set of punch and die. Compared with the traditional structure of die, the cost, the number of assemblies and the development cycle are all reduced by more than 50% by taking the flexible stamping die.
