在冲压生产中,以气流吹件的生产单位,如在气路上加一开关则方便得多,这里介绍一种我们设计的气体开关。一、结构与工作原理气体开关由直角管接头1、8,阀杆2、阀体3、摆杆5、滚轮6、以及圆柱销、六角螺钉等组成。阀体材质为HT15-33灰铸铁,其余均为普通钢材,滚轮6需淬火处理。阀杆2的圆锥体与阀体3的圆锥孔必须经仔细研配,确保其密封性。 In the production of stamping, the production of air blown pieces of production units, such as the gas circuit plus a switch is much more convenient, here is a gas switch we designed. First, the structure and working principle Gas switch by the right-angle pipe joints 1,8, valve stem 2, valve body 3, pendulum 5, wheel 6, and the cylindrical pin, hexagonal screws and other components. Body material HT15-33 gray cast iron, the rest are ordinary steel, wheel 6 to be quenched. The cone of the valve rod 2 and the cone bore of the valve body 3 must be carefully researched to ensure the tightness.
