我厂在试制小马力冷凝式柴油机中,碰到一个铁皮制V形大皮带轮如图1。试制数量少,要求时间急,我厂从未搞过这种产品,经与有关老师傅、技术人员一起研究,并参考日本生产的类似铁皮V形皮带轮,决定采用车床旋压V形槽的工艺,经过多次摸索初步获得成功,解决了新油机试制中的(图2)一个难题,为今后我厂老产品的改进,和类似零件的试制与小批生产取得了一些经验。 I plant in the trial production of small horsepower condensing diesel engine, met a metal-made V-shaped large pulley shown in Figure 1. Small trial production, requiring time, our factory has never engaged in such products, with the teacher and technical staff to study, and with reference to the Japanese production of similar metal V-belt pulley, decided to use lathe spinning V-groove technology . After several initial attempts, it solved a difficult problem in trial production of the new oil engine (Figure 2), and gained some experience for the improvement of the old products in our factory and the trial production and small batch production of similar parts in the future.
