西安市红卫区焊接工具厂是个小厂,生产氧气焊枪及割枪等焊接工具。以前,他们生产的气焊喷嘴全部是车削加工,一个气焊喷嘴的坯料约需直径16毫米空心紫铜棒52毫米长,重0.125公斤,成品重0.075公斤,材料利用率只有60%。去年厂里派人参观了全国机电产品革新展览会,学习了外地少切削无切削加工的先进经验,认识到发展少无切削工艺是增产节约的正确途径,回来结合本厂的实际情况,自己制造了一台对开模冷锻
Hongwei District of Xi’an Welding Tools Factory is a small plant, the production of oxygen welding torch and torch welding tools. In the past, all the gas welding nozzles they produced were turning. The diameter of a gas welding nozzle about 16 mm diameter hollow copper rod 52 mm long, weighing 0.125 kg, finished product weight 0.075 kg, material utilization rate of only 60%. Last year, the factory sent people to visit the National Innovation Exhibition of mechanical and electrical products to learn the advanced experience of foreign countries in cutting and machining without cutting. Realizing that the development of non-cutting technology is the correct way to increase production and save money, the company will come back and manufacture it according to the actual conditions of our factory A pair of mold cold forging
