一种直驱风力发电机定子扇形片的冲压和叠压方法
|
摘要
国内大型电机定子铁心采用扇形片的方式,由于硅钢片材料自身的轧制工艺,材料一般都是中间厚两边薄,冲压的扇形片会有不同程度的厚薄差异,叠压后铁心在周向和径向上会有不同程度的高低波浪,通过选取典型的几个点,测量材料的厚度,进行成台配卷;结合扇形片的外形,设计合理的套裁方案;利用自动送料线连续送料、计数落料的功能,有规律地落料,设计混片装箱工艺和冲片叠压工艺,消除叠压时的高低差,不需要进行剪片叠在冲片中间。
Large domestic motor stator core uses fan film,thin silicon steel material rolling process,the materials are generally the middle of thick on both sides of the fan-shaped piece of stamping have varying degrees of thickness difference laminated after the core in the week select a few typical points,measuring material thickness to the high and low,and have varying degrees of radial wave adult equipped volume;fan films,shape,design sets cut program;automatic feed line for feeding count blanking regularly blanking,the design of mixed-piece packing process and the overlying process of punching,to eliminate the height difference when the overlying do not need to cut the tablets stacked in the middle of the punching.
