本文首先通过类比分析得出,引伸模上粘结瘤的形成过程实质上就是一种引伸中的粘着磨损过程,进而分析了影响粘结瘤形成的三个主要因素:引伸零件材料的性质;引伸件与模具界面的法向压力,引伸中界面局部区域高的温升。从而为消除这类缺陷,采取合理的措施,提供理论基础。 In this paper, the first analogy analysis shows that the formation of the cohesive nodules on the die is essentially a kind of adhesion and wear process in the extension, and then analyzes the three main factors affecting the formation of the nodules: the properties of the material of the extension part; The normal pressure of the interface between the part and the mold, and the high temperature rise in the local area of ​​the extension in the extension. In order to eliminate such defects, take reasonable measures to provide the theoretical basis.
