概述冷挤压是机械制造中的一种金属压力加工工艺,它是对经过处理的毛坯加压通过一个比毛坯横截面较小的型孔而获得产品,挤压后的产品只要少量切削或不再切削加工就可应用。采用冷挤压工艺生产零件,可以大幅度提高劳动生产率,节省原材料,并且保证产品质量,生产成本也得到显著下降。建国三十年以来,这门技术已在各工业部门得到广泛的应用。 Overview Cold extrusion is a metal pressure machining process used in machine construction where the treated blank is pressurized through a smaller hole than the blank and the extruded product is cut with little or no cutting Re-cutting can be applied. Cold extrusion process using parts, can significantly improve labor productivity, save raw materials, and ensure product quality, production costs have also been significantly reduced. Thirty years since the founding of the PRC, this technology has been widely used in various industrial sectors.
