Description
Technical field
The utility model relates to a kind of forming frock of stator coil, especially relates to a kind of coil molding frock of disc-type coreless permanent magnet motor stator.
Background technology
The permanent magnet disc motor of axial magnetic flux has the advantages such as volume is little, power density is large, apply increasingly extensive, structure is simple, efficiency advantages of higher particularly to adopt the disc type permanent magnet motor of the axial magnetic circuit of two p-m rotors, a stator structure to have, and in order to improve electric efficiency further, stator can adopt the structure of iron-core-free, and namely stator coil adopts macromolecular material casting fixing.The stator coil of existing disc-type coreless permanent magnet motor all just directly uses without again shaping after turning to, the winding construction of this motor stator, normally lie in sustained height by the coil of multiple annular and be arranged in circle, the cast of recycling encapsulating material is fixing, owing to being be separated from each other and independently, therefore, make the production technology of stator comparatively complicated between multiple coil, production efficiency is low, cannot produce in batches.Meanwhile, due to the needs of power of motor, when the coil in stator is provided with multilayer, because coil self exists certain thickness, the volume making stator is comparatively large, and then can become more weak when arriving rotor away from the magnetic field that the coil of rotor produces, and magnetic utilance is lower.What operationally mainly utilize due to coil is its corresponding with rotor magnetic steel face magnetic field strafed limit and produce, therefore, after multiple coil superposes mutually and coil strafe limit when can be in same plane, then can solve the defect of above-mentioned existence preferably.But, in current market, there is not this coil molding frock.
Summary of the invention
The utility model provides and a kind ofly can carry out squeezing shaping to the invalid edges of coil and strafe limit after making multiple coil superimposed being in coil molding frock in same plane; Solve in prior art cannot molding of existing superimposed after strafe the technical problem that limit is in the coil in same plane.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of coil molding frock, it is characterized in that: this forming frock includes profiled sheeting and compacted under plate, described compacted under plate offers the coil holddown groove that a pair circumferentially radius vector is spaced apart, coil holddown groove entirety is linear and compacted under plate indent is arranged relatively, compacted under plate is also provided with become to be connected with outer end in coil holddown groove respectively arrange in forming surface and outer forming surface, outer forming surface is provided with and circumferentially distributes for a pair and the outer concave surface that difference opposed coil holddown groove is recessed and epirelief is arranged and outside upper convex surface, outer concave surface and outside upper convex surface are cambered surface, interior forming surface is provided with a pair circumferentially distribution and the respectively interior concave surface of the recessed and epirelief of opposed coil holddown groove and interior upper convex surface, interior concave surface and interior upper convex surface are cambered surface, described upper profiled sheeting is provided with the outer forming blocks coordinated with outer forming surface, the bottom surface of outer forming blocks is identical setting with the shape of outer forming surface and both become matched in clearance, described upper profiled sheeting is also provided with forming blocks in coordinating with interior forming surface, the bottom surface of interior forming blocks is identical setting with the shape of interior forming surface and both become matched in clearance.Limit is strafed by arranging coil holddown groove for what grip coil to be formed, the limit of strafing of hold-in winding is not easily distorted when shaping simultaneously, keep linear, inside and outside coil holddown groove, two ends arrange interior forming surface and outer forming surface respectively, inside and outside gap between forming blocks and inside and outside forming surface is determined according to the thickness of coil to be formed, usually the size being chosen as gap is identical with the thickness of coil to be formed, because interior forming blocks is identical with the shape of outer forming surface with interior forming surface respectively with the bottom shape of outer forming blocks, when extrusion modling, interior forming blocks on upper profiled sheeting and outer forming blocks coordinate with interior forming surface and outer forming surface respectively, the shape of invalid edges inside and outside coil is pressed into identical with the bottom shape of outer forming blocks with interior forming blocks.Therefore, the utility model can be pressed into invalid edges inside and outside coil recessed section and upper convex section of arc, simultaneously can also the limit of strafing of hold-in winding keep linear, coil after shaping can be superimposed with each other use or and other invalid edges be that the coil of circular arc is superimposed and allow the limit of strafing of all coils be in same plane, good forming effect, coil is not easily damaged by pressure.The utility model structure is simple, and convenient formation, formed precision is good.
As preferably, described compacted under plate is provided with the pushing block hole communicated up and down, and in pushing block hole, activity is equipped with associated movable pushing block, and described coil holddown groove, interior forming surface and outer forming surface are located at the top of movable pushing block and are connected with the inwall in pushing block hole.By arranging pushing block hole and movable pushing block, coil holddown groove, interior forming surface can be moved up and down by relative compacted under plate with outer forming surface, thus depart from coil holddown groove after being conducive to coil molding, being convenient in demoulding.
As preferably, the epirelief height of described outside upper convex surface is identical setting with the recessed degree of depth of outer concave surface, and the recessed degree of depth of interior concave surface is identical setting with the epirelief height of interior upper convex surface.Be conducive to compressing after coil to be superimposed with each other use.
As preferably, upper profiled sheeting is also provided with the coil fixed block coordinated with coil holddown groove, distance between bottom coil fixed block and coil holddown groove is identical with the distance between outer forming blocks and outer forming surface, and the distance between outer forming blocks and outer forming surface is identical with the distance between interior forming blocks and interior forming surface.Coil fixed block be arranged so that the limit of strafing of coil can not twist distortion up and down in coil holddown groove, make the limit of strafing of compressing coil remain linear, magnetic utilance is high in use for coil.
Therefore, the utility model has following characteristics compared to existing technology: 1. compacted under plate arranges inside and outside forming surface, the inside and outside invalid edges of coil is corresponding with the position of inside and outside forming surface, upper profiled sheeting is provided with inside and outside forming blocks and coordinates with inside and outside forming surface, invalid edges inside and outside coil is pressed into the shape identical with inside and outside forming surface, coil after shaping can be superimposed with each other use or and other invalid edges be that the coil of circular arc is superimposed and allow the limit of strafing of all coils be in same plane, good forming effect, coil is not easily damaged by pressure, structure is simple, convenient formation, formed precision is good, 2., by arranging pushing block hole and movable pushing block, coil holddown groove, interior forming surface can be moved up and down by relative compacted under plate with outer forming surface, thus depart from coil holddown groove after being conducive to coil molding, being convenient in demoulding.
