Punching processing mold for stator core and stator core manufactured thereby

摘要

The present invention relates to a stamping processing mold for a stator core and a stator core produced thereby, which can minimize the occurrence of burr, minimize an influence such as magnetic flux, reduce the amount of raw materials inserted, and shorten the processes, thereby lowering manufacturing costs. The stamping processing mold for a stator core comprises: an upper mold (140) which is fixedly installed on a press (130) through a fixing means (150); and a left punching portion (110) forming the left of the stator core and a right punching portion (120) forming the right of the stator core, which are fixed to the upper mold (140), respectively, such that a stator core (200) is formed. The left punching portion (110) includes a core body portion punching tip (111) and an eaves portion punching tip (112) such that the left half of a core body portion (212) and an eaves portion (213), around which a coil of the stator core (200) is wound, and a slot portion (214) are formed by punching a strip (40). The right punching portion (120) includes a core body portion punching tip (121) and an eaves portion punching tip (122) such that the right half of the core body portion (212) and the eaves portion (213), around which the coil of the stator core (200) is wound, and the slot portion (214) are formed by punching the strip (40). The right punching portion (120) includes a notching chip (123) forming a notch (215) in a core frame (211) having the slot portion (214) of the stator core (200).
