沈风厂生产的7655型凿岩机的零件螺旋棒和钎套,在过去分别采用模锻和棒料车削,体力劳动强度大,材料利用率低,仅达38％左右,每年都有大量的优质钢材变成了废铁屑。造成了很大的浪费。 300吨油压机制成以后,钎套和螺旋棒实现了温挤新工艺,材料的利用率大大提高,班产量可提高3～5倍,定员由8～9人减少到2～3人,减轻了体力劳动,改变了生产环境。并为国家节约大量的优质钢材。还节约了工时,提高了零件的使用寿命。螺旋棒单件节约材料0.555公斤,按年产15万件计,可节约钢材83吨。钎套单件节约材料0.465公斤,年产15万件计,可节约钢材70吨。
Parts of the 7655 rock drill manufactured by Shenfeng Plant are screwed rods and bushings, which were used for swaging and bar turning respectively in the past. The manual labor intensity is high and the utilization rate of materials is low, only about 38%. A large number of high quality steel materials are produced each year Become scrap scrap. Caused a lot of waste. 300 tons of hydraulic machine into the future, the bushing and screw rod to achieve a warm extrusion process, the material utilization greatly improved, the class output can be increased by 3 to 5 times the number of personnel from 8 to 9 reduced to 2 to 3 people, reducing Manual labor has changed the production environment. And for the country to save a lot of high-quality steel. Also saved working hours and improve the life of the parts. Spiral rod single material saving 0.555 kg, according to an annual output of 150,000, can save 83 tons of steel. Solder a single piece of material to save 0.465 kilograms, with an annual output of 150,000, can save 70 tons of steel.
