在无产阶级文化大革命和批林批孔运动的推动下,我国工农业生产飞跃发展。汽车、农机配件日益增加,原有生产工艺已远不能满足革命、生产发展的需要。目前冷挤压新工艺已在全国逐步普及,它为汽车、拖拉机等配件生产开辟了越来越广阔的前途。根据省一机局和省科技局关于开展黑色金属冷挤压新工艺研究试验的指示,我所技术人员下楼出院,与广州自云山农械厂一起,对解放牌汽车活塞肖冷挤压新工艺进行了研究
Driven by the Great Proletarian Cultural Revolution and the campaign to criticize the proletariat and the proletariat, China’s industrial and agricultural production has leapfrogged development. Automobiles, agricultural machinery parts are increasing, the original production process has been far unable to meet the needs of the revolution, production and development. At present, the new technology of cold extrusion has been gradually popularized in the country and it has opened up a wider and wider future for the production of parts such as automobiles and tractors. According to the provincial bureau and the Provincial Science and Technology Bureau to carry out the cold metal black extrusion technology research and test instructions, I technician downstairs, with the Guangzhou Yunshan farm machinery factory together, Jiefang card car piston Xiao cold squeeze The new technology was studied
