我厂每生产一只显像管需要四个吊耳。(见图1零件图)。原来冲制吊耳需要三道工序(落料—码料—弯曲)用二套模具完成。现进行了改进,依据零件结构特点,采用先落料冲孔后弯曲的传递式跳步模来制造。由原来的手工送料改为自动送料,由压缩空气吹件改为推杆出件。改进后,提高了经济效益,为生产的发展创造了条件。模具结构见图2。
Our factory needs four lugs for producing a picture tube. (See Figure 1 parts map). The original punching lugs need three processes (blanking - code - bending) with two sets of molds to complete. Now improved, according to the characteristics of the structure of the parts, the use of the first punching punching after the transfer of the transfer step mode to create. From the original manual feed instead of automatic feeding, compressed air blown pieces into a putter. After the improvement, the economic benefits have been raised and the conditions for the development of production have been created. Mold structure shown in Figure 2.
