聚氨酯橡胶胀形模不能保证数码发电机转子磁瓦胀压质量。在分析电机转子技术要求及转子外壳结构特征后,在胀形模具中,设计了定位结构、尺寸精度控制结构;设计胀压工序定位装置。使用结果表明:新胀形模与定位装置能保证电机转子胀压定形的技术要求 Polyurethane rubber bulging die can not guarantee digital generator rotor magnetic tile expansive pressure quality. After analyzing the technical requirements of the rotor and the structural features of the rotor housing, the positioning structure and the dimensional accuracy control structure are designed in the bulging mold. The design of the positioning device for the expansion pressure process is designed. The results show that: the new bulging die and positioning device to ensure that the expansion of the rotor pressure setting technical requirements
