In the stator of the electric rotating machine such as motor or generator, need coiling on stator, conventional is all longitudinally be embedded on stator by artificial or coil inserting apparatus by coil.And high for copper factor, have the stator of the reason of grading of major-minor phase to be not easy to a rule, need two to three rules, embedding stator coil out can encase grooved, affects follow-up rule coil stressed, damages coil, affects motor performance.Such as Chinese utility model patent " a kind of pre-integral extension mould ", application number is 201420431066.1, disclose and comprise core rod, push rod, copper sheathing, overall head lock nut and some expansion conical surfaces, core rod is socketed on push rod, push rod rear end is provided with and cylinder connection piece, core rod is cylindrical, core surface axially evenly offers some grooves, the expansion conical surface is arranged in groove, push rod is the cylindrical structural that three sections of diameters increase progressively piecemeal, its reducing place axially arranges First Transition face and the second transition face, First Transition face is that middle part is cylindrical, the structure of the tapered halfpace in two ends, the height of the taper halfpace of front end is higher than rear end, second transition face is the cylindrical structure of the tapered halfpace in front end and rear end, and the columniform height of rear end is higher than the height of front end taper halfpace, spreader cone face comprises the first expansion conical surface, the second expansion conical surface and the 3rd expansion conical surface, the first expansion conical surface, the second expansion conical surface and the 3rd expansion conical surface are list structure, the first expansion conical surface, the bottom of the second expansion conical surface and the 3rd expansion conical surface is provided with open slot and coordinates with push rod, die core front end is provided with overall head lock nut, overall head lock nut is also socketed a taper shaping head, die core back end is provided with the copper sheathing for push rod guiding, every a slice spreader cone surface rear end all arranges an arcuate projections, all expansion conical surfaces are arranged on the inherent rear end of groove and form a tapered slope.This sizing die prodigiosin ensures that mold can accurately, like a cork insert when inserting stator, and has a swelling effect to coil.But, find through practice, the expansion shaping mould of this structure also exists weak point for the copper cash shaping of stator two ends, the expansion conical surface of this structure protrudes expansion by the thrust of guide rod after mold enters stator, its length is the overall dimensions meeting stator, the copper cash being exactly stator inner ring is pressed into by overall time, so when bearing expansionary force, copper cash is pressed into successively by the external force in a direction, the stretching for deformation and length direction produced when expanding for copper cash can be suppressed by mould, it is there is damage that this copper cash for stator embeds.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of stator and expands line mechanism, and it is reasonable in design, and structure is simple, solves in the process of stator expansion shaping and avoids coil to bring the problem of influence of crust deformation product quality because of shaping external force.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is to provide a kind of stator and expands line mechanism, comprises bearing, expansion cylinder, push rod, branch sleeve, lead end extension module, non-lead end extension module and shaping head; Be installed in the horizontal axis hole on described bearing after the piston rod of described expansion cylinder and one end axial restraint of described push rod; The other end of described push rod is provided with described shaping head; To the push rod in shaping head direction, branch sleeve, lead end extension module, non-lead end extension module is also set with successively from bearing; Described lead end extension module comprises the core rod for being set with stator; Described core rod is provided with the expansion conical surface radially protruded; Described non-lead end extension module butts up against described core rod axially; Described push rod is provided with the conehead body corresponding with the inner chamber of described non-lead end extension module.
Preferably, one end of described core rod is docked with described branch sleeve, and its other end docks with described non-lead end extension module.
Preferably, described non-lead end extension module comprises mould circle and expansion block; The axle center hollow of described mould circle defines the inner chamber of non-lead end extension module; Described mould circle is provided with can the described expansion block of radially movement; Described expansion block and described mould circle hinged.
The invention has the beneficial effects as follows: provide a kind of stator to expand line mechanism, it is simple and reasonable, two that establish by separating independently shaping extension module realize the expansion shaping of stator interior coil, ensure that the loop shaping of lead end and non-lead end, overcome the winding deformation amount of different parts, carried out the shaping action of substep by same actuating force, improve the quality of stator expansion shaping, also can improve working (machining) efficiency simultaneously, reduce processing error.
