随着我国社会主义工业建设的飞跃发展,在机械行业中对滚丝模产品的需要量越来越大。滚丝模关键工序是加工牙形工序,过去是用高精度螺丝磨床进行磨削加工,生产效率低,寿命低。无产阶级文化大革命后,在党的正确领导下,我们组织了以工人为主体的三结合攻关小组,对滚丝模产品工艺进行大胆革新创造,试制成功了滚丝模牙形的冷挤压新工艺。生产效率比螺丝磨床提高寿命几十倍,寿命延长3—5倍。下面介绍几个典型工序。
With the rapid development of socialist industrial construction in our country, the demand for rolling mold products in the machinery industry is getting larger and larger. The key process of thread rolling mold is the processing of tooth-shaped process. In the past, the grinding process was carried out by high-precision screw grinder, which has low production efficiency and low life expectancy. After the Great Proletarian Cultural Revolution, under the correct leadership of the party, we organized a three-pronged research team with workers as the main body to boldly innovate the technology of rolling mold products and succeeded in the trial manufacture of a new type of cold extrusion Process. Productivity than screw grinder to improve life expectancy several times, life expectancy 3-5 times. Here are a few typical procedures.
