冷挤压是一种塑性加工工艺。它在不破坏金属的前提下,使金属的形体发生塑性转移,达到少切屑无切屑而使金属成型,可节约大量的金属材料。冷挤压是在压力机上进行,一般每分钟可生产几十个零件,因此生产效率很高。冷挤压件的强度大、刚性好而重量轻,还可获得理想的表面光洁度和尺寸精度。冷挤压的另一特点是可以加工形状复杂的零件。几年来,我厂在以冷挤压代替锻造、拉延及金属切削加工方面有较大的突破,因此也获得了较大的经济效益。
Cold extrusion is a plastic processing technology. It does not destroy the metal under the premise of plastic deformation of the metal body, to achieve less chip-free cutting and the metal forming, can save a lot of metal materials. Cold extrusion is carried out in the press, the general can produce dozens of parts per minute, so the production efficiency is high. Cold extrusion of strength, good rigidity and light weight, but also get the ideal surface finish and dimensional accuracy. Another feature of cold extrusion is the ability to process complex-shaped parts. Over the past few years, I plant in the cold extrusion instead of forging, drawing and metal cutting a greater breakthrough, it also received greater economic benefits.
