New China's first steel ball developer - — Song Shifa

New China's first steel ball developer - — Song Shifa 2019 - 08 - 14 Song Shifa, was born in liaoning province in 1922 after the county ( Wafangdian city) , due to a poor family, he was 16 when grinding ball factory workers to Japanese business. In 1945, he quit. That same year, the people's government took control of the ball bearing factory, Song Shifa again back to the factory, engaged in the repair factory work, become wafangdian bearing factory ( Wafangdian bearing factory) A worker. In June 1947, after the county second liberation. In the spring of 1948, he served as abrasive grinding workshop team leader, lead the workers to carry out the 'red may produce competition. In October 1948, he joined the communist party of China. Mixer liaodong provincial people's government awarded Song Shifa testimonials in early 1949, northeast across the liberation. All the factories, mines in quickly heal the trauma of war, quickly resume production, bearing demand has increased dramatically. But, as the only manufacturer of bearing in the country is facing a faulty situation. Reason is the factory in the day the period, Japan capitalists to monopoly technology, the bearing parts of steel ball and cage on domestic production, only assembled in China. Now factory although returned to the hands of the people, but the machine as early as in 1945 after Japan declared unconditional surrender by Japan tear down. Factory not only unable to make production plan in 1950, and is in danger of comprehensive determination to keep factories and workers idle. As a result, not only more than 1000 workers did not live to do it, most of the country need ball bearing factory and mining machinery will be affected. At this critical moment, the communist party member Song Shifa trial, Jin Deyuan accepted the mission of the steel ball, technicians Ma Hongtu, old xu double bracket will be accepted the trial production tasks. Mixer Song Shifa Song Shifa and team members study technical problems and Jin Deyuan formed a research group, research of steel ball manufacturing methods. They took the machine apart to study first, there is damage, then to repair. But as a result of the capitalist countries for steel ball manufacturing method of a secret, the book also no record, no one is more seen manufacturing process of steel ball, so the research work is very hard. They first production research 'hold the bat' and 'circle of the ball, and continuous improvement. Pieces of northeast journal published 1950 Song Shifa deeds after numerous tests finally overcame all difficulties on the manufacturing, will produce the steel ball method research success. In the process of research, he also taught 40 disciples, make them become skilled workers can separate operation. In September of 1949, China's own manufacturing represented by '610' model of the first set of industrial bearings in wafangdian ball factory was born, and was completed by the end of 13. The end of the ball 50000 sets of production tasks, from now on the history of China can't work with bearings. Song Shifa, Jin Deyuan, Ma Hongtu, xu pairs for the development of Chinese bearing industry made great contributions, liledagong for the people. Song Shifa successively rated factory special model workers, provincial special labor model, and the northeast industry of the people's government awarded the first medal, also was named the national model worker, on behalf of the Chinese first generation of bearing workers took part in the September 1950 in Beijing for a meeting of deputies to the national model worker of workers, peasants and soldiers. （ Source: the chorography dalian)
