在冷挤压过程中、经常由于导向不好,凸模和凹模不同心而造成模具寿命不长。因此要延长模具寿命,提高产品质量,合理地解决导向问题是十分重要的。目前,大部分工厂把叨削加工改成冷挤压加工,开始都是在没有专用的冷挤压机床的情况下,采用一般的摩擦压力机、液压机、曲柄或偏心压力机 In the cold extrusion process, often due to poor guidance, not the same mold and die caused by die life is not long. Therefore, to extend the life of mold and improve product quality, a reasonable solution to the problem of orientation is very important. At present, the majority of the factory to cut into four machining operations cold extrusion, the beginning is not in the case of a dedicated cold extrusion machine, the use of general friction press, hydraulic machine, crank or eccentric press
