我厂有一台九辊平板机,要平整大量的卷板。卷板一般宽1.5m、板厚8mm以下;钢板卷筒直径1～1.4m。平整前,先要拆卷,亦即将钢板卷筒的头卡出、拉长、砸平后,方能送入平板机上下两排压辊之间,然后平板机才开始工作。我们设计制造了一台液压传动钢板卷筒拆卷送进机。经几年使用,效果良好,它具有结构简单、操作方便的特点,造价只有同类产品的四分之一,结构见图。上图为结构图,下图为原理图,简介如下。操作程序先将心轴8穿于钢板卷筒的孔中,然后将卷筒放在两平行轴Ⅰ及Ⅱ上,同时,卷筒心轴两端的轴承座放入支架2的开口槽内。液压系统开始工作,先使两油缸1的活塞杆同时缩回,以带动摆杆13、滚轮架心 I plant a nine-roll flatbed, to flatten a large number of Coil. Coil generally wide 1.5m, thickness 8mm below; plate reel diameter of 1 ~ 1.4m. Flat before the first roll, the plate will reel the first card out, stretching, smashing, before the plate can be fed into the upper and lower rows between the pressure roller, and then began to work flat. We designed and manufactured a hydraulic drive coil removal machine. After several years of use, the effect is good, it has a simple structure, easy operation, the cost is only one-quarter of similar products, the structure shown in Figure. The picture above is the structure diagram, the picture below is the schematic diagram, the brief introduction is as follows. The operation procedure first passes the mandrel 8 through the hole of the steel plate reel, and then places the reel on two parallel shafts I and II. At the same time, the bearing seats at both ends of the mandrel are put into the opening slots of the bracket 2. Hydraulic system began to work, first make the piston rod of the two cylinders at the same time retracted to bring the swing rod 13, roller frame
