喷油嘴喷孔内口深处针阀体内部,钻喷孔时残留的棱边、毛刺无法用一般方法清除。受工艺限制,国内喷油嘴图纸对喷孔内口也不注加工要求,故喷油嘴生产厂也不安排喷孔内口加工工序。喷孔内口残留棱边、毛刺直接影响喷嘴流量和喷雾质量,制造厂无法排除此内残,只好在喷嘴出厂前做喷雾检查时,将不合格的喷嘴报废,由于工艺条件的限制造成了大量的工时和材料的浪费,且使出厂产品质量难于稳定。本文介绍一种能够对喷油嘴喷孔内口进行加工的电解工艺。文中说明了此工艺所需设备和加工过程,提供了必要的工艺参数,并提示了影响电解加工效果的因素。电解加工设备简单,生产效率高,劳动强度低,可以加工一般机械加工方法无法加工的部位,如喷油嘴喷孔内口,是一种大有发展前途的工艺方法。
Injector nozzle hole deep inside the needle valve body, the residual drilling edge of the jet, burrs can not be removed by the general method. By the process constraints, the domestic nozzle drawings on the nozzle hole does not note processing requirements, so the nozzle manufacturer does not arrange the nozzle hole processing steps. The remaining edge of the nozzle hole, burr directly affect the nozzle flow and spray quality, the manufacturer can not rule out the residual, had to spray the nozzle before the factory inspection, the unqualified nozzle scrapped, due to process conditions caused a large number of restrictions Working hours and material waste, and the quality of manufactured products is difficult to stabilize. This article describes an electrolytic process that can process the inner orifice of a nozzle orifice. The article describes the equipment required for this process and process, providing the necessary process parameters, and prompted the impact of electrolytic machining factors. Electrolytic processing equipment is simple, high production efficiency, low labor intensity, Machinable general machining methods can not be processed parts, such as the mouth of the nozzle orifice, is a promising technology.
