Abstract:

The production of fan components such as stator iron cores and casings must rely on the support of technological equipment. Using the three-pin twisting slanting stator core stack laminating tools, the correct positioning of the stator punches (sheddings) were solved. And then they were pressed into the bearing support. The interstices compaction stator core with a pitch twisting was obtained. The iron core sawtooth dislocation notch of traditional laminated die were avoided. To the plastic frame and aluminum alloy bracket, by the combined case structure which was pressed by hollow rivets, and using the floating positioning case riveting tool, the high connection strength, good overall quality and high production efficiency could be obtained.

Key words: stator iron core, laminate, combined case, riveting, twisting slanting, floating positioning
