以生产实际需求为导向,研制一套新型的柔性内孔喷丸装置。对柔性喷嘴喷丸参数进行优化,以解决传统的长深孔、弯曲类零件内孔喷丸工艺存在的强度失稳、弯曲角度区域覆盖率不高的问题,保证长深孔弯曲类零件的内壁喷丸质量。利用该装置对内径15 mm,弯曲角度130°,孔径比为0.01的零件内孔进行喷丸,饱和点喷丸强度为0.381 mm A,覆盖率达到100%,满足技术要求。 To produce the actual demand-oriented, the development of a new type of flexible bore shot blasting device. To optimize the shot peening parameters of flexible nozzles to solve the problems of the strength instability and the low coverage of bending angle in the conventional long hole and curved hole injection peening, Shot quality. The device was used to shot peen the inner diameter of 零15 mm, the bending angle of 130 ° and the aperture ratio of 0.01. The shot peening intensity was 0.381 mm A and the coverage reached 100%, meeting the technical requirements.
