五、橡胶密封圈的修边工艺橡胶密封圈的质量好坏直接影响机械产品的质量,质量差的橡胶密封件是造成机械产品泄漏的主要因素之一,而引起密封圈质量不好的主要原因之一就是修边问题。目前,我国采用的传统修边方法大量是落后的手工修边,只有少部分采用机械或半机械修边。采用手工修边工艺,无论修边工人技术如何熟练,刀具的歪斜也在所难免。因此,要使密封圈的边修得光洁整齐,特别要使尺寸较小、精度较高的密封圈修边符合要求是很困难的,而且所花的工时很多,效率很低。橡胶密封圈的修边是橡胶密封圈成型、硫化、修边三道工序中最后一道工序。如修边这道工序不过关,则前两道工序的劳动也白费了。手工修边工序所占用的劳动力也比前面两道
Fifth, the rubber seal trimming process The quality of rubber seals directly affect the quality of mechanical products, poor quality rubber seals is caused by mechanical products, one of the main factors of leakage, which caused the bad quality of the main ring One is trimming the problem. At present, a large number of traditional trimming methods adopted in our country are outdated manual trimming, and only a few of them adopt mechanical or semi-mechanical trimming. Trimming process by hand, no matter how skilled edge trimming workers, tool skew is also inevitable. Therefore, to make the edge of the sealing ring clean and tidy, in particular, to make smaller, high precision sealing ring trimming meet the requirements is very difficult, and the time spent a lot of work, the efficiency is very low. Trim of the rubber seal is a rubber seal forming, curing, trimming the last three processes in the process. If trimming this procedure but pass, then the first two processes of labor wasted. Manual trimming processes occupied by the labor than the previous two
