The specific embodiment
Further illustrate the present invention below in conjunction with accompanying drawing
With reference to accompanying drawing:
stator of the present invention, composite die is moved in the qi of chong channel ascending adversely of rotor list groove, comprise the die punching machine with mould, described mould comprises mold, with the bed die that is provided with the die hole that mates with mold, described mold 1 comprises cylinder 11, stator slot punch 12, rotor slot punch 13, pumping board 14, upper bolster 15, upper padding plate 16, punch retainer 17, stripper 18, described upper bolster 15 and described upper padding plate 16 are installed on the drift of die punching machine, in the gap of described pumping board 14 between described upper bolster 15 and described upper padding plate 16, and an end of described pumping board 14 is connected with the piston rod of cylinder 11, described stator slot punch 12, rotor slot punch 13 are embedded in respectively in the chute of described upper bolster 15, and described stator slot punch 12 and described rotor slot punch 13 sides all arrange groove, punch retainer 17 with punch pad 171 is installed on described upper padding plate 16, and an end of described punch pad 171 embeds in the groove of described stator slot punch 12 and rotor slot punch 13, the side fixed rotor groove pumping board cushion block 131 of described stator slot punch 12 towards a side fixed stator groove pumping board cushion block 121 of pumping board, described rotor slot punch 13 towards pumping board, the side that described stator slot pumping board cushion block 121 and described rotor slot pumping board cushion block 131 protrude to pumping board one side are equipped with respectively and the first slot to make way 141 of pumping board 14 relevant positions and the projection of the second slot to make way 142 couplings.
