我厂张永林同志利用滚珠滚压工件,以提高工件表面光洁度。经使用证明,效果良好。工具如附图所示。1是钢珠,共3粒,其中与工件表面接触的一粒可较其他两粒大一些。钢珠1装在套管2内,套管2用螺钉9、心轴8紧固在刀杆4的斜孔内。在套管2内装有支持钢珠1的支座3、弹簧5和垫圈6以及用来调整弹簧对钢珠压力大小的螺钉7。用这种工具采用多次滚压,均匀地缩小工件尺寸。一般说来,第一次压缩0.01～0.015公厘,第二次压缩0.003
My factory Zhang Yonglin comrades use roller rolling parts, to improve the surface finish. The use of proof, the effect is good. Tools as shown in the figure. 1 is a steel ball, a total of 3, of which the surface of the workpiece in contact with a larger than the other two larger. Steel ball 1 is installed in the sleeve 2, the sleeve 2 is screwed 9, and the mandrel 8 is fastened in the inclined hole of the arbor 4. The sleeve 2 is provided with a support 3 for supporting the steel ball 1, a spring 5 and a washer 6, and a screw 7 for adjusting the pressure of the spring on the steel ball. Use this tool with multiple rolling, even to reduce the size of the workpiece. In general, the first compression 0.01 ~ 0.015 mm, the second compression of 0.003
