我厂生产的一种圆柱形零件,需要在表面打上号码字。这道工序过去是手工加工的,效率很低。在技木革新运动中,李耀清同志利用一部小卧铣,只增加一些装置,改成了滚字用的工具。生产效率提高10倍以上。工具的构造如附图所示。图中1是滚轮,装在铣刀轴上。滚轮1用40号钢制成,淬火后的硬度应当达到RC45左右。2是底座,用铸铁做成,装在铣床的工作台上。3是打字用的钢印,用螺钉固定在底座2上。4是调整钢印3用的斜铁,装在底座2上。5是装工件用槽子。
A cylindrical part produced by our factory needs to be numbered on the surface. This process used to be manual processing, low efficiency. In the technological innovation movement, Comrade Li Yiu-ching made use of a small horizontal milling machine to increase the number of devices and change it into a tool for typing words. Productivity increased more than 10 times. The construction of the tool is shown in the attached drawing. Figure 1 is a roller, mounted on the cutter shaft. Roller 1 made of 40 steel, hardened hardness should reach about RC45. 2 is the base, made of cast iron, mounted on the milling table. 3 is a typing stamp, with screws on the base 2. 4 is used to adjust the stamp 3 with the iron, mounted on the base 2. 5 is installed with the workpiece slot.
