电机转子的单头冲槽模,特别是刀形槽模,如图1所示,它的α角随着电机的规格不同而有6°、8°、10°……等变化。同时由于它的形状不是对称图形,因而在高速冲床上进行单槽冲槽时夹持较困难。我厂原是用V形通用模柄夹持,这种夹持由于槽模不对 The single-headed notching die of the motor rotor, especially the knife slot die, is shown in Fig. 1. Its α angle varies by 6 °, 8 °, 10 °, etc. depending on the specifications of the motor. At the same time because of its shape is not a symmetrical figure, and therefore in the high-speed punch on a single slot when notching more difficult. My factory was originally V-shaped mold holder handle, this clamping is not the right slot die
