带锯床主要部件有:底坐;床身、立柱;锯梁和传动机构;导向装置;工件夹紧;张紧装置;送料架;液压传动系统;电气控制系统;润滑及冷却系统。
液压传动系统由泵、阀、油缸、油箱、管路等元辅件组成的液压回路,在电气控制下完成锯梁的升降,工件的夹紧。通过调速阀可实行进给速度的无级调速,达到对不同材质工件的锯切需要。
电气控制系统由电气箱、控制箱、接线盒、行程开关、电磁铁等组成的控制回路,用来控制锯条的回转、锯梁的升降、工件的夹紧等,使之按一定的工作程序来实现正常切削循环。
润滑系统开车前必须按带锯床润滑部位(钢丝刷轴、蜗轮箱、主动轴承座、蜗杆轴承、升降油缸上下轴、活动虎钳滑动面夹紧丝杆)要求加油。蜗轮箱内的蜗轮、蜗杆采用30号机油油浴润滑,由蜗轮箱上部的油塞孔注入,箱仙面备有油标,当锯梁位于最低位置时,油面应位于油标的上、下限之间。试用一个月后应换油,以后每隔3-6个月换油1次,蜗轮箱下部设有放油塞。
