日本三井工作所总厂有一电机铁芯冲压车间,其电机铁芯片的冲压、计数、叠压工序均在模具中自动完成。叠压成整体的转子和定子,分别从模具中被推出。这种模具是在电机铁芯级进冲裁模的基础上改进而成的,除冲裁部分与一般电机铁芯级进模相同外,还增加了计数、叠压和推出装置。在叠压时,凹模还可以按要求进行回转,用于叠压带螺旋槽的转子。 Japan’s Mitsui Works Plant has a motor core stamping shop, the motor core chip stamping, counting, stacking process are automatically done in the mold. Laminated into a whole rotor and stator, were pushed out of the mold. This kind of mold is improved on the basis of the motor iron core progressive blanking die. Besides the same blanking parts as the general motor iron core progressive die, the counting, overlapping and pushing devices are added. When stacked, the die can also be rotated as required for laminating the rotor with helical groove.
