我厂将五铧犁的四种主梁除锈改为机械化操作,并将除锈、刷漆两道工序改为一次完成,提高工效两倍多,改善了劳动条件。生产作业线示意图见图1。除锈(图1、图2) 工件由传动链送入除锈室,当接触讯号甲时,气动缸乙推上钢丝轮刷与工件接触,气动缸甲返回原位,此时左、右、上、下四个钢丝轮刷同时工作,清除工件表面锈层,灰尘和铁锈随吸尘器排出。当工件与讯号甲分离后,气动缸乙将上钢丝 I plant will be five plow four main beam derusting mechanized operation, and rust, paint two processes to be completed once, to improve work efficiency more than twice, improve working conditions. Production line diagram shown in Figure 1. Rust (Figure 1, Figure 2) The workpiece from the transmission chain into the derusting chamber, when the contact signal A, pneumatic cylinder B push the wire wheel brush contact with the workpiece, the pneumatic cylinder back to its original position, then left and right, Up and down four wire wheel brush work at the same time, remove the rust surface of the workpiece, dust and rust discharge with the vacuum cleaner. When the workpiece and the signal separation, pneumatic cylinder B will be on the wire
