大家知道,圆形工件的滚花纹(擂丝)工作是在车床上进行的。我厂钳工祁志龙同志看到车工任务很紧,而又有一大批工件需要擂丝。于是他就动脑筋研究,在冲床上试验滚压花绞成功,效果很好,提高效率10陪以上。这种工具的结构如图所示。1是上模座,装在冲床滑块上。2是上模板,用螺丝固定在上模座上。3是托工件用的弹簧片。4是下模座。5是下模板,用螺丝固定在下模座上。6是靠山。上模板和下模板上刻有方向相反的花纹(一个向左倾斜,一个向右倾斜,斜度30°)。下模板上下边要做成斜
As we all know, the work of knurling of the circular workpiece is carried out on a lathe. Our factory fitter Qi Zhilong saw the lathe job is very tight, but there is a large number of pieces need to wire. So he used his brains to study, in the press on the successful test rolling knot, the effect is very good, to improve efficiency 10 to accompany the above. The structure of this tool is shown. 1 is on the mold base, mounted on the press slider. 2 is the template, with screws on the mold base. 3 is supporting the use of spring pieces. 4 is the next mold base. 5 is the next template, with screws fixed to the lower mold base. 6 is the backdrop. The upper and lower stencils are engraved with opposite patterns (one to the left, one to the right and a slope of 30 °). The top and bottom of the template to be made oblique
