Abstract

The invention relates to a dividing die for punching a slot for a motor stator whole-circle punching sheet, which can lower die manufacture cost. When a stator groove profile is punched, the inner bore of the stator is simultaneously cut, and thus the stator punching sheet is processed into a finished product after the groove profile is punched. Meanwhile, the function can be realized no matter how small a gap between a stator and a rotor is so as to prevent a punch from cracking because of too small gap. The dividing die comprises an upper die and a lower die, wherein the upper die is connected with a punch press; a positioning device is arranged between the upper die and the lower die; the upper die fixing plate of the upper die is provided with a groove profile punch and a dividing punch corresponding to the lower die; the lower die comprises a lower die blade block; the lower die blade block is installed on a lower die holder and is provided with a groove-type lower die blade matched with the groove profile punch and the dividing punch; and a guiding and spacing device is arranged between the upper die and the lower die.

Description

[0001] technical field [0002] The invention relates to a groove cutting and splitting die for a full-circle punching piece of a motor stator. Background technique [0003] The motor has a stator punch and a rotor punch. For a stator punch with a diameter of less than 1.25m, it is usually designed as a circular sheet. The rotor punch is nested inside the stator punch, and the shape is also a circular sheet. [0004] When punching the sheet, the traditional process is: blanking the outer circle of the stator - punching the keyway - punching the stator groove shape - punching the rotor groove shape - separating the stator and rotor punching pieces. The molds that need to be designed include: outer circle blanking die for stator punching, single groove punching for stator and rotor slot and keyway, separation die for stator and rotor punching (with drop shaft hole). Using this punching process, the separation of the stator and the rotor requires the design of a special separa...
