    • PURPOSE:To accurately manufacture a die cast rotor by forming slots at a steel plate for a rotor, reducing several slots of them, forming pores and notches in the vicinity of the outer peripheral side, sequentially caulking a laminated core at the part and laminating them. CONSTITUTION:A plurality of part of slot group 12 of a laminated iron plates 11 for a die cast rotor are reduced in size. Cut and erected parts 15 and pores 16 for escaping a skew which are continued to the parts 15 are formed in the vicinity of the outer peripheral sides. The parts 15 are sequentially moved in one direction of the circumference to be press-fitted by a press, and the laminated iron plates for a die cast rotor are slightly twisted, caulked and laminated while utilizing the pores 16.
    • 目的:通过在转子的钢板上形成槽,精确地制造压铸转子,减少其几个槽,在外周侧附近形成孔和凹口,顺序地在层压芯上挤压并层压它们 。 构成:压铸转子的层叠铁板11的槽组12的多个部分的尺寸减小。 在外周侧附近形成切割和竖立的部分15和用于逸出与部分15连续的歪斜的孔16。 部件15在圆周的一个方向上依次移动,通过压力机进行压配,并且用于压铸转子的层压铁板在使用孔16的同时稍微扭曲,铆接和层压。
