Description

A kind of single-groove punch-die for Cone-shaped electric machine rotor
Technical field
The utility model relates to a kind of single-groove punch-die for Cone-shaped electric machine rotor.
Background technology
Cone-shaped electric machine is the special motor of a kind of structure, its stator and rotor core are all conical structures, it is all different large so just requiring stator and the rotor punching internal-and external diameter of each sheet, and the single impression die for Cone-shaped electric machine punching press is generally divided into stator slot shape single-groove punch-die now, diameter of stator bore is cut single-groove punch-die and rotor slot shape single-groove punch-die; Stator outer diameter, cramp groove and rotor shaft hatch were gone out by blanking die before this by its manufacturing process, again with stator slot shape single-groove punch-die punching press stator slot shape for rotor shaft hatch location, the diameter of stator bore that then changes the outfit is again cut punch die punching press, make stator separated with rotor punching, use again rotor single-groove punch-die stamping rotor flute profile, complete a whole set of operation.
This technique must be changed rotor slot shape mould after stator slot shape punching press completes, carry out two times punch, its shortcoming is: the punching press of rotor flute profile all must be located with the axis hole of rotor, take the axis hole center of circle as basic point rotary punching, and axis hole is almost interference fit with coordinating of positioning disk, if the fit clearance of axis hole and positioning disk is excessive, when High Rotation Speed punching press, will cause punching whipping and cause punching uniformity poor, and even punching is scrapped.And stator must footpath crosses twice punching press and just can complete, production efficiency is low.
Utility model content
The utility model object is that the defect that exists for prior art provides a kind of stator slot shape mould and diameter of stator bore are cut to the single-groove punch-die that mould unites two into one.
The utility model for achieving the above object, adopts following technical scheme: a kind of single-groove punch-die for Cone-shaped electric machine rotor, comprise top mold frame and lower mold holder, and described top mold frame is connected with the guide pillar guiding arranging on described lower mold holder by the guide pin bushing arranging;
The top of described top mold frame is provided with die shank, and its underpart is provided with punch fixing plate; The bottom of described punch fixing plate is provided with stator punch-head assembly; The bottom of described stator punch-head assembly is provided with outer stripper, and the upper end of described outer stripper is fixed in described top mold frame by a plurality of the first bolt assemblies;
The top of described lower mold holder is provided with die cushion block, and the top of described die cushion block is provided with die, and the center of described die is provided with discharging jacking block, and described discharging jacking block is fixed on described lower mold holder by the second bolt assembly; Described stator punch-head assembly comprises that corresponding with the stator slot shape arranging on described die and diameter of stator bore circular arc respectively stator slot shape drift and diameter of stator bore cut drift; The height that described in the aspect ratio of described stator slot shape drift, diameter of stator bore is cut drift exceeds 0.6-0.8mm.
Further, described the first bolt assembly comprises the first bolt, on described the first bolt between described outer stripper and described punch fixing plate, is provided with the first discharging spring assembly.
Further, described the second bolt assembly comprises the second bolt, is positioned at described die cushion block centre bore and is provided with the second discharging spring assembly matching with described the second bolt.
The beneficial effects of the utility model: single-groove punch-die of the present utility model can complete diameter of stator bore separation in punching press stator slot shape, under clamped one time, just can complete like this stator slot shape punching press separated with internal diameter, both reduced the input of equipment, improve the uniformity of flute profile, improved again production efficiency.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1, be a kind of single-groove punch-die for Cone-shaped electric machine rotor, comprise top mold frame 6 and lower mold holder 1, top mold frame 6 is connected with guide pillar 7 guiding that arrange on lower mold holder 1 by the guide pin bushing 8 arranging; The top of top mold frame 6 is provided with die shank 20, and its underpart is provided with punch fixing plate 5; The bottom of punch fixing plate 5 is provided with stator punch-head assembly 11; The bottom of stator punch-head assembly 11 is provided with outer stripper 4, and the upper end of outer stripper 4 is fixed in top mold frame 6 by a plurality of the first bolt assemblies; The top of lower mold holder 1 is provided with die cushion block 2, and the top of die cushion block 2 is provided with die 3, and the center of die 3 is provided with discharging jacking block 10, and discharging jacking block 10 is fixed on lower mold holder 1 by the second bolt assembly; Wherein, described stator punch-head assembly 11 comprises that respectively stator slot shape drift and the diameter of stator bore corresponding with the stator slot shape arranging on described die 3 and diameter of stator bore circular arc cut drift (not shown in FIG.).For carrying out punching press successively to rotor punching, the height that the aspect ratio diameter of stator bore of stator slot shape drift is cut drift exceeds 0.6-0.8mm.
In single-groove punch-die of the present utility model, the first bolt assembly comprises the first bolt 16, on the first bolt 16 between outer stripper 4 and punch fixing plate 5, is provided with the first discharging spring assembly 13.In addition, the second bolt assembly comprises the second bolt 15, is positioned at die cushion block 2 centre bores and is provided with the second discharging spring assembly 12 matching with this second bolt 15.
During use, the punch die of utility model is arranged on single groove impact machine bed, regulate punch die to the centre distance of positioning disk, because this punch die is the mould that one pair of stator slot shape and a punching press of diameter of stator bore complete, after single groove punching is started working, because the stator slot shape drift arranging is cut drift higher than diameter of stator bore; Therefore, stator slot shape drift must first contact material and stamp out stator slot shape, and it is descending that slider of punch continues, and the diameter of stator bore circular arc interaction that diameter of stator bore is cut on drift and die 3 forms punching press for the second time again, completes the separated of stator punching and rotor punching.When slide block starts after return, discharging jacking block 10, under the rebound effect of the second discharging spring assembly 12, ejects die 3 by rotor punching, completes the work separated with rotor diameter of stator slot shape waste material; Now lathe dividing spindle drives punching rotation, when slide block declines again, repeats above-mentioned action, until follow procedure is set, stamps out stator punching.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
