发展和采用生产率高、节省原材料的制造工艺对国民经济的发展具有积极意义,几乎全部冷成形工艺均属此列。民德国营Neudorf厂加工套筒件的变薄拉伸是一种特殊的冷成形工艺,它为合理加工连轴件开辟了广阔前景,已获得极大的经济效益。这种变薄拉伸工艺属于冷体积成形,以精密钢管为原材料,可以加工全部套筒形零件,例如各种规格、品种的接轴套和轴套。加工轴
The development and adoption of manufacturing processes that have high productivity and save raw materials are of positive significance for the development of the national economy. Almost all of the cold forming processes fall into this category. The thinning of the machined sleeve part of the German state-owned Neudorf plant is a special cold-forming process that opens up vast prospects for the rational machining of the shaft couplings and has achieved significant economic benefits. This thinning drawing process is a cold-forming process that uses precision steel tubing as raw material to process all sleeve-shaped parts such as hubs and bushings of various sizes and sizes.
