GQ50钢筋切断机结构设计与运动仿真

【摘要】

钢筋切断机是把钢筋切成所需长度的专用机械,在大型建筑工地上的应用非常广泛。钢筋切断机分为机械传动和液压传动两种。机械传动式钢筋切断机,工作时大都采用电动机经一级三角带传动和三级齿轮传动减速后,带动曲轴旋转,曲轴推动连杆使滑块和动刀片在机座的滑道中作往复直线运动,使活动刀片和固定刀片相错而切断钢筋。GQ50型钢筋切断机，其剪切运动是由一偏心轮连杆机构完成的。但是由于切断机机体内腔狭小，在装配曲轴连杆时比较困难。尤其是在使用中发生故障需要维修时，拆卸曲轴连杆更加不容易，给维修造成很大的不变，因此在不改变设备功能的情况下，我对曲轴连杆机构做了一些改进。改进后的偏心轮结构直接从机体的注册孔中装入和取出。而不必拆卸连杆，大大简化了装配程序，减轻的工人的劳动强度。同时也极大的方便了维修，还简化了零件的工艺过程，取得良好的经济效益。
