瓶阀主要零件阀体系采用直径38毫米的HPb59—1铅黄铜棒料,加热后模锻成形,其坯料是3～4米的长棒料经铣切下料而成,这种工艺材料利用率很低。我们经过多次改进设计,研制了黄铜棒材剪切新工艺,获得较显著的经济效益和社会效益。黄铜棒料剪切原工艺采用锯片铣刀下料,铣断一片需5～6分钟,即浪费铜料,又污染环境,影响工人健康。新工艺方法简便,省时、省力、省工具、省材料。以年产40万只计算,每年可节约53040元。1.冲剪铅黄铜的技术要求 HPb59—1黄铜主要成份为Cu57～60％;Pb0.8～1.9％,棒料直径为38毫米长64±1毫米;要求靠近刃处的外径压塌≯1.5毫米;切口处的垂直度不大于1.5毫米;冲剪后的毛刺与飞边不大于1毫米。2.铅黄铜棒料剪切装置和操作原理如图所示,先将铅黄铜棒料装入送料筐中,使其
Valve parts of the main valve system uses HPb59-1 diameter of 38 mm lead brass rod material, heated forging forming, the blank is 3 to 4 meters long bar by milling cut material, the use of such materials Very low rate. After many improvements in design, we developed a new technology of brass bar cutting, to obtain more significant economic and social benefits. Brass bar stock cutting process using saw blade cutter cutting, milling a need 5 to 6 minutes, that is, waste of copper material, but also pollute the environment, affecting the health of workers. The new process is simple, time-saving, labor-saving, provincial tools, provincial materials. Calculated with an annual output of 400,000, saving 53040 yuan per year. 1. Punching lead brass technical requirements HPb59-1 brass main components of Cu57 ~ 60%; Pb0.8 ~ 1.9%, bar length of 38 mm long 64 ± 1 mm; required near the edge of the outer diameter of the pressure Collapse ≯ 1.5 mm; notch at the verticality of not more than 1.5 mm; punching after burr and flash not more than 1 mm. 2. Lead brass rod cutting device and operating principle shown, the first lead brass rod into the feeding basket, so that
