矫直辊装配液压螺母的改造

Transformation of Hydraulic Nut for Assembling Straightening Roller

莱钢型钢厂大H型钢生产线矫直辊装配液压螺母是矫直机进行工艺装配的专用设备,长期存在漏油现象。经分析,其结构设计不合理是造成泄露的原因。将O型圈由原来嵌装在活塞环的环形槽内,改为嵌装在螺母的环形槽内;对活塞环的结构、材料和加工工艺进行一些改造;并针对性的制定合理的装配要点。该项改造实施后,矫直辊装配液压螺母3年多未出现泄露。

The hydraulic nut for assembling straightening roller is the special equipment for technologic assembly of straightener in H beam plant of Laiwu iron and steel Co.,Ltd,but the oil leakage has been existed on the hydraulic nut for a long time.The reason is unreasonable structural design after analyzing.O-ring was built in the ring groove of the piston ring.Now built the o-ring in the groove of the hydraulic nut,the configuration,material and the artifactitious technics are also transformed.In addition,established reasonable and targeted key points of assembly.After that,the oil leakage has been not found on the hydraulic nut for assembling straightening roller for three years.
