一、概况我车间专门产生磨床传动系统中的各种液压部件,其中大部分是各种规格的油泵。随着祖国工农业生产的飞跃发展,对各类油泵的需要量越来越多,越来越迫切,经常处于供不应求的状态。如何介决供求矛盾,关键在于油泵齿轮。因其几何形状复杂,精度要求高,加工周期长,严重地影响泵产量大幅度的增长,故必须寻找新的工艺措施,以满足产品发展需要。工人老师傅们遵照毛主席关于“什么事情都应当执行勤俭的原则”的教导,自己动手利用废料氧化铁采用少无切削新工艺之一——粉末冶金成型,制造油泵齿轮。见图1。在战无不胜 First, an overview of my workshop dedicated grinder drive system produces a variety of hydraulic components, most of which are a variety of pumps. With the rapid development of the industrial and agricultural production in the motherland, the demand for various types of oil pumps is more and more increasing and pressing, and often in short supply. How to solve the contradiction between supply and demand, the key lies in the pump gear. Because of its complex geometry, high accuracy, long processing cycle, a serious impact on pump output growth, it must find new process measures to meet product development needs. According to Chairman Mao’s teachings on the principle of thrifty what should be done, the workers and their masters made their own use of waste iron oxide to manufacture oil pump gears using powder metallurgy, one of the few non-cutting new processes. see picture 1.
