Abstract
Disclosed is a sizing die for a stator core, which consists of an upper die, a crest slab, a riveting jig head, two return boards and bearings. The stator core is hitched to the core shaft of a lower die, an upper cylinder moves downwards, and when the upper die presses the stator core, a slanting wedge contacts with the bearings to push the two return boards to fold slowly. When the upper die disposes the stator core in place, after a swage spring is compressed with a certain distance, the return boards adjust the outer circle of the stator to be in place, then the upper cylinder continues to move downwards, a shaping plate goes into the room between the two bearings inside a slipper block to push the slipper block to move forward; after that, the shaping plate contacts with a hard positioner to enable the riveting jig head to strike a dovetail into a dovetail groove; in this way, riveting and buckling are accomplished. The sizing die can dispose the stator core in place, ensures the consistency of the shaping of the outer circle of the stator and good shape of the dovetail at the rivet joint, and avoids the upturning of the topmost plate at the rivet joint of the core, thus greatly improving efficacy.
Description
Technical field:
The utility model relates to electrical micro-machine, particularly relates to the shaping mould of the stator core in a kind of electrical micro-machine.
Technical background: old-fashioned electric machine iron core all adopts whole stamped from sheetstock to become required circular configuration, and the chip that several stamped from sheetstock are become is stacked together then, and employing at last is welded into bolted mode and connects.The stator piece that adopts this mode to produce, not only the magnetic loop iron loss of iron core is many, the more important thing is that waste of raw materials is a lot, can not meet the needs of production.We carry out the button riveting of dovetail after adopting stator to be wound into circle by the vertical bar of punching out again, have so not only saved great deal of raw materials, and have avoided the magnetic loop loss of iron core.The mode of dovetail button riveting is satisfied the demand, guarantee slice not easy flanging of going up most of iron core riveted joint place, guarantee the consistency of iron core shaping.Be electrical micro-machine industry technology personnel problem demanding prompt solutions.
Summary of the invention:
The purpose of this utility model is exactly the shaping mould that a kind of stator core will be provided, and it can solve the problem of dovetail button riveting, satisfies and produces needs.The purpose of this utility model is to realize like this, a kind of shaping mould of stator core is made up of patrix, top board, die, slide plate, bearing, it is characterized in that: the central authorities of loam cake are provided with the binder spring, the right and left of loam cake is provided with guide plate, and described guide plate is provided with several patrixes; The rightmost of loam cake is provided with forming board, and forming board is inserted in the groove of the hard location that is arranged on base plate the right in the middle of passing the two bearings that is provided with on the slide block; Described slide block is arranged on above the base plate, and the left side of slide block is provided with die; The front of described cover plate, back also are provided with wedge respectively, described wedge respectively be arranged on slide plate on bearing contact, slide plate is arranged on the base plate; The central authorities of described base plate are provided with mandrel, and base plate is provided with several and the corresponding push rod of patrix around the mandrel, and push rod is provided with top board.The utility model can make stator core be pressed onto the position, and has guaranteed the consistency of stator cylindrical shaping, and the excellent in shape of dovetail riveted joint place, and the flange of having avoided iron core riveted joint place to go up most slice has improved effect greatly.
