专用车辆前围拉延模具的设计

The design of the front panel extending for the special vehicles

简要地介绍了产品结构及工艺补充，通过CAE拉延软件的模拟分析，找出了拉深不足的区域，并提出采用增加拉深筋的方法。为此对前围拉延模具进行了改进设计。

The paper gives a brief introduction of the products construction and the technology complementarities. By means of the model analysis of the CAE Software, finding out the areas, which are lack of extending and putting forward, the methods of intensifying the extending so that improve the design of the front panel extending stroke.
