Description
Technical field
The present invention relates to a kind of laminated mold, and in particular to a kind of Simple stator iron core laminated mold.
Background technology
Stator core（Shown in Fig. 1）For low-speed permanent-magnet synchronous motor, its middle part has endoporus, positioned at endoporus surrounding,
And some side openings being circumferentially all provided with, and the fixing hole for being connected.Because its stator and rotor gap is only 0.05mm, because
This as motor core component stator core its to laminate precision be most important guarantee.It is by a number of stator
During punching is put into stator core laminating die after managing piece, in the case where positioning precision is ensured, repeatedly pressed using hydraulic press,
Final iron core product must closely non-loosening, the flatness of iron core, perpendicularity and uneven degree index must all be controlled between piece
Within 0.05mm, repeatedly pressing mold positioning that this requires to be developed is reliable, axial limited location and easy to operate when compressing for system.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of stator core laminated mold, and the mould structure is simple, operation
Convenient, positioning is reliable.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of Simple stator iron core laminated mold, including：
Pressing plate and stripper setting up and down, stator punching group is located between pressing plate and stripper；
Groove lining bar vestibule, it extends downward stripper from pressing plate upper surface, and including be circumferentially all provided with least two, each
Groove lining bar is respectively arranged with the groove lining bar vestibule；
Elastic component, with axial elasticity deformation power, it is located at stripper lower section；Preferably, elastic component is metal or nonmetallic bullet
Property part, it is further preferred that elastic component be rubber parts or spring, most have choosing, elastic component is rubber parts；
Base assembly, is fixed in elastic component lower section, and limited location is constructed between the base assembly, elastic component and the stripper
Chamber, the built-in finite place piece of limit chamber, the locating part has the upper surface parallel with stator punching group surface；
Positioning core assembly, is fixed in base assembly, and coordinate with the interior interporal lacuna of stator punching group；
Riveting pawl, positioned at the rivet lower section of stator punching group, and when stator punching group is compressed, the riveting pawl can cut stator
The rivet of punching group simultaneously carries out turning over riveting.
In order to avoid the stagger ratio error of the inside and outside edge of stator core, in another preferred scheme：The positioning core assembly
By the locating core with taper cylinder, and the resilient sleeve composition being placed on the outside of locating core；The resilient sleeve has and locating core
The corresponding cone shaped body of taper cylinder, the diameter of the cone shaped body is up-small and down-big, and cone shaped body is highly interior more than stator punching group
Hole is highly.When resilient sleeve receives downward pressure, resilient sleeve can be micro descending, while producing radial dilatation, makes resilient sleeve
The locating effect of zero clearance is produced between outer rim and stator punching group endoporus.
In another preferred scheme：The locating part is to be sheathed on the spacing collar on the outside of locating core.
In another preferred scheme：The resilient sleeve is the resilient sleeve of lateral opening.
In another preferred scheme：Riveting pawl chamber, institute are also configured between the base assembly, elastic component and the stripper
The bottom for stating riveting pawl is fixed in the base assembly, and top can go out the outlet in riveting pawl chamber.
In another preferred scheme：The end of the riveting pawl be intermediate projections, both sides be recessed it is corrugated.
In another preferred scheme：The base assembly includes base plate and backing plate setting up and down.
The method laminated using above-mentioned mould is：
（1）Several stator punchings to be installed are pressed the alignment of mark groove by reason piece, and rivet is installed in corresponding hole, form stator
Punching group；
（2）Resilient sleeve first filled in the endoporus of the stator punching group managed, then by the groove of groove lining bar insertion stator punching group,
When groove lining bar is two, during two groove lining bars are inserted into this group of symmetrical side opening of punching respectively（It is i.e. circumferentially equal
If）；
（3）Iron core clamping, the stator punching group for still loosening obtained as above is covered in the lump together with the resilient sleeve and groove lining bar inserted
Enter locating core and the corresponding groove lining bar location hole of stripper（Second alleged by its part for belonging to groove lining bar vestibule, i.e. embodiment
Chamber）In；Finally cover pressing plate；
（4）Repeatedly press, turn on the power device, impose downward pressure to pressing plate, axially loose stator punching group by pressing plate gradually
Compress, while elastic component is pressurized thinning, the end incision rivet of riveting pawl carries out turning over riveting, as elastic component is further pressed
Contracting, when the lower plane of stripper and the upper plane of locating part are collided, pushes and obtains spacing, and now riveting is just inserted in riveting pawl end
Nail bottom outlet simultaneously completes riveting；
（5）Demoulding pickup, cancels pressure, and remove demoulding pickup by pressing plate and stator core.Again under clamping just can enter
Riveting.
The beneficial effect that the present invention is reached：
, first to stator punching group elastic compression row riveting again, tight ness rating is higher between making stator punching for this mould；With stator punching
By progressively elastic compression, stripper is also pressurized descending group, and when its lower plane encounters the upper plane of locating part, pressurization terminates,
In the presence of rigid limit, the flatness of stator punching group is ensured (otherwise its plane undulate)；As a result of
The resilient sleeve of taper fit, and in the final stage of riveting, its top is compressed axially by pressing plate, under resilient sleeve is micro
OK, while producing radial dilatation, make to produce the desired position effect of zero clearance between resilient sleeve outer rim and stator punching group endoporus,
Thoroughly avoid the stagger ratio error of the inside and outside edge of stator core.
This mould structure is simple and convenient to operate, and preferably solving discrete piece and being difficult positioning, axial pre-pressing causes stator iron
Core face deformation and the uneven problem of stator core periphery.As bulk production especially experimental production, with product
Quality stabilization, risk are small, smail investments and quick rerurn advantage.
