HPb59-1铅黄铜是光学仪器中广泛采用的一种有色金属材料,常用的加工工艺有铸造和切削加工等方法,上述工艺方法存在着材料利用率低(30％左右)、生产效率低和铸件有砂眼气孔等缺陷。为了解决上述工艺存在的问题,江南光学仪器厂研制成功了铅黄铜零件的塑性成型工艺,该厂采用此工艺生产的生物显微镜的转动板、镜筒滑座等部分零件已大批量投入生产,制件已达到设计技术要求,技术经济效果显著。
HPb59-1 lead brass is widely used in optical instruments, a non-ferrous metal materials, commonly used processing methods casting and cutting methods, the above methods there is a low material utilization (about 30%), low production efficiency and Castings have trachoma stomatal defects. In order to solve the problems of the above process, Jiangnan Optical Instrument Factory successfully developed the plastic molding process for lead-brass parts. The parts of the rotating microscope board and slide holder produced by this factory have been put into mass production in large quantities, Parts have reached the design and technical requirements, significant technical and economic results.
