我厂产品中有矿山链条。矿山鏈条中有三个零件(侧鏈节、中鏈节和鏈銷)是利用鍛模鍛出的。由于它的数量很大,所以锻模的需要量也很多,如果利用一般的方法来制造,所需要的时间很长,不能满足需要。本厂老鍛工北京市劳动模范王玉楨同志,试用热锻反印法来制造得到成功,使鍛模制造工时由每套侧鏈节锻模需要45小时,降低到10小时;制造周期由20～30日,缩短到2～3日,解决了鍛模供应问题。
Mine products in mine chain. There are three parts of the mine chain (side chain links, chain links and chain pins) is forged using a forging die. Because of its large number, so the need for a large number of forging die, if the use of general methods to manufacture, the time required for a very long, can not meet the needs. The old factory forging workers in Beijing Wang Yuzhen model worker comrade, trial hot forging anti-imprinting method to create success, the forging workmanship from each side chain section die for 45 hours, reduced to 10 hours; manufacturing cycle from 20 to 30 Day, shortened to 2 to 3 days, to solve the problem of forging die supply.
