Description
Technical field
Motor accessory technical field is the utility model is related to, more particularly, to a kind of hinge type stator iron core and its shaping mould
Tool.
Background technology
Existing motor stator core is that punching is formed by stacking.Punching is integrally formed ring type structure.By it is interior around
Machine coiling on the stator core for be provided with dielectric.The interior line mouth around machine could be around through the groove on stator core, therefore,
The width of groove is greater than the width of line mouth, i.e. notch will do width.And the wide rotor that can cause magneto of motor stator notch exists
Great cogging torque is produced during rotation, this not only can cause large effect to the usage experience of client, as feel has tying point,
Torque pulsation is big etc., and constrains application of the motor in high-precision control field.Meanwhile line mouth is past during coiling
Occur when moving again and beat skeleton, line mouth easily breaks, and coiling is difficult, adds expense, long processing time, delay production.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of hinge type stator iron simple in construction, reliability is high
Core and the mould for manufacturing the structure stator core, cause coiling difficult for solving original stator core because notch is narrow
The problem of.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of hinge type stator iron core, including
Core body, if described core body is spliced by stem structure identical stator block head and the tail, described stator block left-hand end
Face is provided with raised line, and described stator block its right end face is provided with groove, by the raised line on a stator block and another stator block
On groove interference fit, multiple stator blocks are spliced into core body circlewise, described stator according to this connecting method
Block is formed by stacking by multiple structure identical stator punchings, and described stator punching is in I-shaped, described stator punching left end
Provided with the lug in circular arc, described stator punching right-hand member is provided with the recess in circular arc, and described multiple stator punchings are folded
Afterwards, described lug is built up described raised line, and described recess is built up described groove.
Further improved as the utility model, described multiple stator punchings are built up by way of mould punching
Stator block, described stator punching are provided with riveting groove, and described riveting groove refers to that described stator punching front is provided with square
The depression of shape, the position of the corresponding depression in the back side of described stator punching are provided with projection.
A kind of hinge type stator iron core forming mould, including die ontology, described die ontology are set successively from left to right
There are lug punching station, recess punching station, stator punching shaping station and folded riveter positions, set on described lug punching station
There is lug piece, described recess punching station is provided with recess piece.Stator block is manufactured by this mould.
Compared with prior art, it is splicing structure the utility model has the advantage of core body, assembling is easy, multiple
Stator punching is overlapped into I-shaped stator block, and after multiple stator blocks are spliced into core body, the width of notch becomes big, is easy to iron
Core coiling, solve the problems, such as that original stator core causes coiling difficulty because notch is narrow, occur what is damaged in core body in addition
Place, as long as changing corresponding stator block or stator punching, greatly reduce the maintenance cost of stator core.
