我厂产品鲤鱼钳的固定用螺丝,早先是在车床上切制的;但因批量大,产量又低,所占工时极多,常因螺丝供应不上而使钳子不能及时装配。大跃进以来,我用改用土滾压机来搓螺纹,不仅产量高,而且质量亦很好。现把工作中的情况,作点滴经验介绍如下,以供参考。一、液压螺纹的工作原理用搓板搓螺纹时,把一块较短的搓板(静搓板)固定在滾压机的巢内,另一块较长的搓板(动搓板)装在滾压机的滑枕上。由于偏心轮的带动,故形成往复运动,这时把要加工的螺丝毛坯放在 I plant products common carp clamp with screws, previously cut in the lathe; but because of large quantities, low output, account for a lot of man-hours, often due to the supply of screws and pliers can not be timely assembly. Since the Great Leap Forward, I have used a soil roller to thread, not only high output but also good quality. Now the work situation, bit by bit experience as follows, for reference. First, the working principle of the hydraulic screw thread with a washboard, a shorter washboard (static washboard) fixed in the roller nests, and the other a long washboard (dynamic washboard) mounted on the roller ram . Due to the eccentric wheel drive, so the formation of reciprocating motion, then to be processed screw blank on
