据了解,C_(62A)、C_(50)型敞车木改铁端墙横带端头压制工艺:目前各货车厂均采用把切割好的横带用氧乙炔焰烘烤后以大锤敲击成型;或将其送至压力机上用模型冷压成型的工艺。用前一种工艺制作,氧乙炔焰烘烤时间较长,用大锤敲击劳动强度大、工效低、成本高;用后一种工艺制作,虽然可以冷压成型,但是由于工件(横带)比较笨重(24号槽钢重约84公斤),上下压力机时需要用起重设备吊运,辅助时间较长,效率也
It is understood that C_ (62A), C_ (50) gondola wood to iron end of the end of the end of the tape pressing process: At present, the van are used to cut a good band with oxyacetylene flame baking sledgehammer Forming; Or sent to the press with the model cold forming process. With the former process, oxyacetylene flame longer baking time, with a sledgehammer, labor-intensive, low efficiency, high cost; with a production process, although the cold forming, but due to the workpiece (horizontal band ) Is bulky (24 channel weight about 84 kg), the need for lifting the lifting press lifting equipment, auxiliary longer, the efficiency is also
