遵照伟大领袖毛主席关于“自力更生”、“艰苦奋斗”的教导,为加速发展我国的汽车工业,我厂试制了J45—315型闭式双动拉伸压力机,其外观如图所示。本机已于1973年9月进行了全面鉴定(其中包括内外滑块的单独和联合负荷试验,用户实际拉伸件的生产性试验),性能完全达到了设计要求,并满足了使用的工艺要求,获得用户的好评。这台机器是在贯彻厂内外三结合的基础上试制成功的。本机是由济南铸造锻压机械研究所设计的。在投产前我厂又进行了重点复校。在设计过
In accordance with the guidance of Chairman Mao on “self-reliance” and “arduous struggle” by the great leaders, in order to accelerate the development of China’s auto industry, our factory trial-produced a J45-315 closed double acting drawing press whose appearance is shown in the figure. The machine has been fully appraised in September, 1973 (including separate internal and external sliders and joint load test, the actual production of the user’s tensile test), the performance has fully met the design requirements, and to meet the requirements of the process , Access to user’s praise. This machine is in trial implementation of the successful combination of the factory inside and outside the three. This machine is designed by Jinan Foundry Machinery Research Institute. Before putting into production, our factory carried out the key re-school. In the design
