红旗造船厂铜工车间板金工人研制成功一台螺旋卷管机。该机可将宽为130毫米、厚为0.8毫米的镀锌钢带卷制成圆管,供作船舶上的通风管用。以前,通风管全部靠板金工人用手工制作,生产效率低,劳动强度大。该机制成后,每分钟可以卷制圆管2米,能提高工效24倍。所卷制的圆管强度高,圆度好,隙口耐腐蚀,密封性能好。该机操作简单,而且比手工操作要节省材料。螺旋卷管机主要由进料机构和成型机构两
Hongqi Shipyard copper workshop sheet metal workers successfully developed a spiral coiling machine. The machine can be 130 mm wide and 0.8 mm thick galvanized steel strip into a round tube for the ventilation pipe on the ship. In the past, all ventilation pipes were made by hand by sheet metal workers with low productivity and labor intensity. The machine is made, the tube can be rolled per minute tube 2 meters, can improve work efficiency 24 times. The tube produced by the high-strength, good roundness, slot corrosion-resistant, good sealing performance. The machine is simple to operate, and save material than manual operation. Spiral winding machine mainly by the feeding mechanism and molding two
