机械加工中的金属冷挤压技术,具有省工时、省材料、提高工件性能、降低成本等优点,因而广泛应用于轻工、军工、仪表、航空等工业部门。国营新兴仪器厂在采用冷挤压技术生产纯铁和低炭钢工件时,必须先将毛坯进行酸洗—磷化—胶体石墨和饱油表面润滑处理,工序繁多,酸雾严重,劳动条件差,并且污染环境。为了改进现行工艺,改善生产条 Metal cold extrusion technology in machining, with the working hours, provincial materials, improve the performance of the workpiece, reduce costs, etc., which are widely used in light industry, military industry, instrumentation, aviation and other industrial sectors. State-owned emerging equipment factory in the use of cold extrusion technology, the production of pure iron and low carbon steel parts, the workpiece must be first pickling - phosphating - colloidal graphite and oil-saturated lubrication of the surface, a large number of processes, severe acid fog, poor working conditions , And pollute the environment. In order to improve the current process, improve the production of the bar
