图1是我厂生产的165F柴油机的起动摇手柄,手柄套筒2是用直径Φ20毫米,壁厚1毫米的钢管做成的。过去75°的圆弧槽与右端面的封口是在车床上滚压成形的。钳工用割管刀下料后送到加工车间滚压加工,滚压完后再返回钳工车间装配。手柄套筒的生产过程需经过两个车间,同时还需要搬运工来回搬运。车工完成滚压工序需6分钟,计工时钱0.3元(厂价:车工:3元/时,钳4:1
Figure 1 is a starting crankshaft handle of 165F diesel engine manufactured by our factory. Handle sleeve 2 is made of steel pipe with diameter of Φ20mm and wall thickness of 1mm. The last 75 ° arc groove and the right end of the seal is formed on the lathe. Fitter with a cutting knife after cutting into the processing plant rolling, rolling back and then returned to fitter workshop assembly. Handle sleeve production process through two workshops, but also need to move porters handling. Car workers to complete the rolling process takes 6 minutes, total working hours of 0.3 yuan (factory price: turner: 3 yuan / hour, clamp 4: 1
