我厂二车间生产锗低频管3AX31.在装配工序中除小球、锗片早已实现空吸模具化外,装大球还是手工操作.最近对大球装配工艺进行了大胆革新,并获得了成功.过去一直是用园柱型大球作集电极,其直径为1毫米,高为0.5毫米.园柱型大球是用小冲床冲制而成.由于材料是纯铟,很软,冲制后容易粘结在一起.用这种大球装配不易实现空吸模具化,装配费工费时,且耗损量大.在当前开展的增产节约运动中,
I plant two germanium billet production workshop 3AX31. In the assembly process in addition to small balls, germanium film has long been achieved suction mold, the big ball or manual operation. The recent big ball assembly process was a bold innovation and achieved success . In the past has been using a large cylindrical ball collector, the diameter of 1 mm, 0.5 mm high. Large ball cylinder is made of small punch. Since the material is pure indium, very soft, red Easily bonded together after the use of such a large ball assembly is not easy to achieve suction mold, assembly time and labor costs, and wear and tear in the current campaign to increase production and conservation,
