我厂在生产液压支架用的各种油缸和叉车油缸中,活塞杆体镀后抛光出现各种轻重不同的波纹和螺旋纹。开始时由于检测方法不当,致使部分有螺旋纹的杆体流入了装配工序,直到用户验收提出时才发现。我们通过改进验证,认为采用如下目测方法检验镀前和镀后抛光杆体,才能杜绝带有螺旋纹和波纹的杆体流入下道工序。 I plant in the production of hydraulic support used in a variety of fuel tanks and forklifts, piston rod body after plating polishing various different severity of the ripples and spirals. Initially due to improper detection methods, resulting in part of the threaded rod into the assembly process, until the user acceptance was found. We through the improvement of verification, that the visual inspection method using the following pre-polished and polished rod body, in order to eliminate with spiral and corrugated rod body flow into the next process.
