Description
Technical field
This utility model relates to a kind of mould, especially relates to a kind of stator core punching, finishing inner bore composite die.
Background technology
In process of production, because of the regulation that production technology, product technology require, there is following problems: 1, iron core bracket can deform upon after welding in electric motor car stator core assemblies, in order to eliminate the deformation that welding stress produces, hole size requires over press finishing；2, iron core bracket assembly needs after completing to increase hole, location, a few place at rack surface, and this operation, after finishing inner bore, uses forcing press punching press.
Existing technique is the operation adopting two equipment to be respectively completed punching and finishing inner bore, although requirement can be met, but production efficiency is not high, because of two procedures, the position error of stator core assemblies can be produced both form and position tolerance errors relatively greatly simultaneously, add the workload in later stage.
Utility model content
For the problems referred to above, this utility model provides a kind of stator core punching, finishing inner bore composite die, and it can simultaneously complete the operation of punching and finishing inner bore on an equipment, improves production efficiency, has saved equipment investment and place.
This utility model provides a kind of stator core punching, finishing inner bore composite die, and including upper die and lower die and steel ball, described upper mould is fixed with and slips hole drift and pierce punch, and the hole drift that slips is positioned at mould center, and pierce punch is positioned at and slips outside the drift of hole；Described counterdie correspondence slips drift place, hole through hole, and through-hole aperture is more than slipping hole drift external diameter, and described steel ball is positioned at counterdie central hole, and ball size is suitable with stator core central bore size, and steel ball external diameter is less than counterdie through-hole aperture.
Preferably, described upper mould includes interconnective upper bolster, upper padding plate, train wheel bridge and upper de-plate from top to bottom；Described counterdie includes interconnective lower bolster, external stripping plate lower plate, lower bolster and die shoe from top to bottom.
Preferably, the surface configuration of described upper bolster contact upper padding plate has the groove of through upper bolster side, and groove is positioned at directly over pierce punch, and pumping board in the grooves and can position along the slip of groove length direction.
Preferably, slip hole drift described in and pierce punch is both secured on train wheel bridge.
Preferably, described pierce punch top is connected to punching push rod.
This utility model can realize on an equipment positioning instant successively can simultaneously complete the operation of punching and finishing inner bore, improve production efficiency, it is to avoid the position error that second positioning produces, and has saved equipment and place.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 to Figure 3, this utility model provides a kind of stator core punching, finishing inner bore composite die, and including upper mould 1, counterdie 2 and steel ball 6, described upper mould 1 is fixed with and slips hole drift 3 and pierce punch 4, the hole drift 3 that slips is positioned at mould 1 center, and pierce punch 4 is positioned at and slips outside hole drift 3；Described counterdie 2 correspondence slips hole drift 3 place through hole, and through-hole aperture is more than slipping hole drift 3 external diameter, and described steel ball 6 is positioned at counterdie 2 central hole, and steel ball 6 size is suitable with stator core central bore size, and steel ball 6 external diameter is less than counterdie 2 through-hole aperture.
Preferably, described upper mould 1 includes interconnective upper bolster 11, upper padding plate 12, train wheel bridge 13 and upper de-plate 14 from top to bottom；Described counterdie 2 includes interconnective lower bolster 22, external stripping plate 23, lower plate 24, lower bolster 25 and die shoe 26 from top to bottom.
Preferably, the surface configuration that described upper bolster 11 contacts upper padding plate 12 has the groove of through upper bolster 11 side, and groove is positioned at directly over pierce punch 4, and pumping board 7 in the grooves and can position along the slip of groove length direction.
Preferably, slip hole drift 3 described in and pierce punch 4 is both secured on train wheel bridge 13.
Preferably, described pierce punch 4 top is connected to punching push rod 5.
nullDuring work，Upper mould 1 is arranged on press，Install at upper mould 1 place and slip hole drift 3 and pierce punch 4，Stator core is installed and is positioned on counterdie 2，Steel ball 6 is placed in stator core central hole，Start press，The hole drift 3 that slips down moves under the drive of upper mould 1，Steel ball is headed in stator core centre bore，Final steel ball 6 drops out through stator core centre bore from counterdie 2 centre bore，Pierce punch 4 is to the punching of stator core relevant position simultaneously，Complete punching technology，Go up mould 1 afterwards up to exit，Stator core after finishing inner bore and punching is ejected by the ejecting mechanism within counterdie 2，Change stator core to be processed，And the type according to stator core is different，May select and extract pumping board 7 out LAP and position，When press moves downward, pierce punch 4 up moves after contacting workpiece and is retracted into the gap of pumping board 7，It is not carried out punching technology，And only realize the function of finishing inner bore，Whole production process efficient quick.
Certainly; the present invention also can have other various embodiments; when without departing substantially from present invention spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and deformation according to the present invention, but these change accordingly and deformation all should belong to the scope of the claims appended by the present invention.
