采用冷挤压对金属的加工,无论在技术上和经济上它都有很大的优点。 1.节约原材料,冷挤压是一种塑性加工工艺,使金属体积作出塑性转移,达到少切屑无切屑而使金属成形。这样就避免了在切削加工时而形成的大量金属废屑,大大节约原材料,我厂波段开关轴套,采用冷挤压后材料消耗仅为原来切屑加工的十四分之六点二,即原来一个零件的黄铜现在可以加工二点二五个,每一个零件节约材料7.8克。 The use of cold extrusion of metal processing, both technically and economically it has great advantages. 1. To save raw materials, cold extrusion is a plastic processing technology, making the metal volume to make plastic transfer, to achieve less chip-free and make the metal forming. This avoids the formation of a large number of metal cutting waste in the process, greatly saving raw materials, I plant band switch sleeve, the use of cold extrusion material consumption after the original chip processing only six two-two, that is, the original one The brass part now can process 2.25 parts, saving 7.8 grams of material per part.
