小型精密薄板冲裁模,采用滚动导向件较适宜。目前国内广泛使用的结构中,以钢球作为滚动体,滚动导向件已作为冷冲模的标准件(见图1),列入了国家、部和企业的各种标准。但在模具设计时选用这些标准件和生产使用中,还存在一些不合理的地方,致使滚动导向的优越性未能充分显示出来,甚至会出现模具损坏事故或导向件的过早研损。本文介绍导向结构的设计和选用导向件的原则以及设计验算方法。 Small precision sheet blanking die, rolling guide more appropriate. Currently widely used in the structure, the ball as a rolling body, rolling guide has been used as the standard parts of the die (see Figure 1), included in the national, ministries and enterprises of various standards. However, in the mold design use of these standard parts and production use, there are still some unreasonable place, resulting in the superiority of rolling-oriented failed to fully display, or even die damage accident or guide premature damage. This article describes the design of the guide structure and the principle of the selection of guides and design verification method.
