冷挤压是无切削加工的一种,它是毛坯在室温下加一定压力,使金属产生塑性变形充满模腔制造零件的一种方法。这种方法具有生产效率高,能加工形状复杂的零件,并具有零件强度高、精度好、表面质量好、原材料消耗少成本低等优点。以球头肖—推力杆这个零件为例,年产73万件时,与切削工艺相比,可节约钢材1554吨,提高生产率6倍,降低成本326万
Cold extrusion is a kind of non-cutting, it is a blank at room temperature plus a certain pressure, so that the plastic deformation of the metal-filled cavity is a method of manufacturing parts. The method has the advantages of high production efficiency, capable of processing complex shaped parts, high strength of parts, good precision, good surface quality and low consumption of raw materials. Taking ball head Shaft - Thrust rod as an example, with an annual output of 730,000 pieces, it can save 1554 tons of steel compared with cutting technology, increase productivity by 6 times and reduce costs by 3.26 million
