通过对气缸挤压成形三种工艺方案的比较,选择了一种更为合理的方案。设计了整套挤压模具,利用DEFORM-3D模拟挤压成形过程,通过模拟结果,分析工艺的合理性,进而改进模具以成形合格零件。采用本文中所述的加工工艺,可以减轻毛坯质量45%以上,有显著的经济效益。 Through the comparison of three kinds of process schemes for the extrusion of the cylinder, a more reasonable solution was chosen. The whole set of extrusion die was designed, the extrusion process was simulated by DEFORM-3D, the rationality of the process was analyzed by simulation results, and then the die was improved to form the qualified part. Using the process described in this article, you can reduce the quality of more than 45% of the rough, with significant economic benefits.
