上海东海阀门厂系生产各类气体钢瓶阀的专业工厂。各类瓶阀的阀体大部分采用HP59—1黄铜棒料热锻后加工而成。目前锻造工艺采用传统的压力机模锻。以液化石油气瓶角阀YSF—1为例,阀体用φ40×63铜棒,重665克,飞边138克,材料利用率为79％。按月产8万件计算,全年飞边消耗铜材158吨,耗费35.8万元左右。为节约铜材和资金,降低成本,提高经济效益。该厂与上海交通大学、上海模具研究所
Shanghai Donghai Valve Factory production of various types of gas cylinder valve professional factory. Most of the valve body of each type of valve is made of hot-forged HP59-1 brass bar stock. Forging process using the traditional press die forging. To liquefied petroleum gas cylinder angle valve YSF-1, for example, the body with φ40 × 63 copper rods, weighing 665 grams, 138 grams of flash, material utilization rate of 79%. Calculated on a monthly basis of 80,000, the annual consumption of copper 158 tons of flash, cost 358,000 yuan. To save copper and capital, reduce costs and improve economic efficiency.
