我厂使用的 JA21—160型压力机系锻造流水线中的关键设备,工作规范为单次行程,日行程利用次数达万余次。由于离合器原设计存在某些先天性薄弱环节,导致故障频发,维修工时较多,给大批量生产带来十分不利的影响。通过故障原因分析,我们对多发性故障部位的结构或薄弱零件作了改装或改进,大大 The JA21-160 press used by our factory is the key equipment in the forging line. The work specification is a single trip, and the daily trip uses more than 10,000 times. Due to the existence of certain congenital weaknesses in the original design of the clutch, frequent failures are caused and more man-hours are required for maintenance, which has a very adverse effect on mass production. Based on the analysis of the cause of the failure, we modified or improved the structure or weak parts of the multiple fault locations.
