针对原喷管喷喉加工中存在的问题,根据钢球挤压加工的特点,决定采用钢球挤压加工喷管喷喉工艺。随后介绍了工艺计算过程,并进行了工艺试验。结果表明,该工艺能提高零件的尺寸精度、表面质量和生产效率,降低生产成本。钢球挤压工艺能满足零件大批量生产的要求,可对同类型零件的加工提供借鉴。 Aiming at the problems existing in the processing of the throat of the original nozzle, according to the characteristics of the extrusion processing of the steel ball, it is decided to use the steel ball to extrude and process the nozzle throat spraying process. Then introduced the process of calculation, and conducted a technical test. The results show that the process can improve the dimensional accuracy of parts, surface quality and production efficiency, reduce production costs. Steel ball extrusion process to meet the requirements of mass production parts, can provide reference for the processing of the same type of parts.
