上海郑兴泰汽车机件制造厂接到了2000套红旗牌拖拉机变速箱的总成任务,要求在年内完成,而且包括转向机构、后桥、动力输出轴等各种齿轮,内中有六种螺旋伞齿轮,计10000多只,经初步核算,需增添大立铣床、大万能铣床6台,进行改装,方能完成上项螺旋伞齿轮的任务。但机床搞不到,问题没有办法解决。在大跃进的形势紧逼下,厂的领导确定了解决关键问题的方向,亲自动手,依靠群众的智慧和力量,经过40天的苦战,制造了加工螺旋伞齿轮的专用土铣床四台,并改装了一台旧滚床、一台旧铣床,才将螺旋伞齿轮的任务完成。
Shanghai Cheng Xingtai Auto Parts Factory received 2,000 Hongqi brand tractor gearbox assembly tasks required to be completed during the year, but also to the steering gear, rear axle, PTO and other gear, there are six kinds of spiral bevel gear , Accounting for more than 10,000 only, after preliminary accounting, the need to add a large vertical milling machine, a large milling machine 6 can be modified to complete the task of spiral bevel gear on the project. However, the machine can not be found, there is no way to solve the problem. Under the pressing situation of the Great Leap Forward, the leaders of the factory determined the direction of resolving the key issues and started their own hands. Rely on the wisdom and strength of the masses, after 40 days of hard fighting, they manufactured four dedicated earth milling machines for spiral bevel gears Refit an old rolling bed, an old milling machine, spiral bevel gear to complete the task.
