我厂主导产品JZC、JZM系列混凝土搅拌机均采用双锥搅拌筒,筒体进料锥和出料锥为5mm厚钢板卷制而成。过去卷制锥体在一台W11-20×2500三辊机械传动卷板机上进行。由于该卷板机已使用近20年,长期滚压锥形料口,料周边带有气割下料时留下的高硬度焊渣。锥形工件移动速度和辊轴线速度不相等,焊渣将两传动辊表面拉伤并出现了数道3mm深的沟槽,导致辊表面和工件表面接触不良,经常出现打滑、卡滞现象。 此台卷板机已经大修两次。如果采用以前的修理方法,仅
Our factory leading products JZC, JZM series of concrete mixers are used double cone mixing tube, barrel cone and the material feed cone for the 5mm thick steel rolling. In the past, the cone was rolled on a W11-20 × 2500 three-roll mechanical drive bending machine. Since the coiling machine has been used for nearly 20 years, long-term rolling conical material mouth, with the material around the cutting gas leaving the high hardness of welding slag. Conical workpiece moving speed and roller axis speed are not equal. The welding slag will pull the surface of the two driving rollers and produce a few channels of 3mm deep, resulting in poor contact between the roller surface and the workpiece surface, often skidding and jamming. This machine has been overhauled twice. If using the previous repair method, only
