Description
Technical field
The present invention 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, so just require the stators and rotators punching internal-and external diameter of each sheet be all different greatly, the single impression die now for Cone-shaped electric machine punching press is generally divided into stator slot shape single-groove punch-die, diameter of stator bore cuts 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 rotor shaft hatch location stator slot shape single-groove punch-die punching press stator slot shape, the diameter of stator bore that then changes the outfit again cuts die punch, stators and rotators punching is separated, use rotor single-groove punch-die stamping rotor flute profile again, complete a whole set of operation.
This technique must change 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, with the axis hole center of circle for 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, punching whipping will be caused when High Rotation Speed punching press and cause punching uniformity poor, and even punching is scrapped.And stator must be crossed twice punching press and just can complete in footpath, production efficiency is low.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of single-groove punch-die of stator slot shape mould and diameter of stator bore being cut mould and uniting two into one.
The present invention for achieving the above object, adopts following technical scheme: a kind of single-groove punch-die for Cone-shaped electric machine rotor, comprises top mold frame and lower mold holder, and described top mold frame is led with the guide pillar that described lower mold holder is arranged by the guide pin bushing arranged and is connected;
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 multiple first bolt assembly;
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 stator slot shape drift corresponding with the stator slot shape that described die is arranged and diameter of stator bore circular arc respectively and diameter of stator bore cuts drift; The height that diameter of stator bore described in the aspect ratio of described stator slot shape drift cuts drift exceeds 0.6-0.8mm.
Further, described first bolt assembly comprises the first bolt, and described first bolt between described outer stripper and described punch fixing plate is provided with the first discharging spring assembly.
Further, described 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 matched with described second bolt.
Beneficial effect of the present invention: single-groove punch-die of the present invention can complete diameter of stator bore and be separated while punching press stator slot shape, the punching press that stator slot shape is separated with internal diameter just can be completed like this under clamped one time, both the input of equipment had been decreased, improve the uniformity of flute profile, turn improve production efficiency.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
Detailed description of the invention
Shown in Fig. 1, for a kind of for the single-groove punch-die of Cone-shaped electric machine rotor, comprise top mold frame 6 and lower mold holder 1, top mold frame 6 is led with the guide pillar 7 that lower mold holder 1 is arranged by the guide pin bushing 8 arranged and is connected; 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 multiple first bolt assembly; 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 stator slot shape drift corresponding with the stator slot shape that described die 3 is arranged and diameter of stator bore circular arc respectively and diameter of stator bore cuts drift.For carrying out punching press successively to rotor punching, the height that the aspect ratio diameter of stator bore of stator slot shape drift cuts drift exceeds 0.6-0.8mm.
In single-groove punch-die of the present invention, the first bolt assembly comprises the first bolt 16, and 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 bore and is provided with the second discharging spring assembly 12 matched with this second bolt 15.
During use, the punch die of invention is arranged on single groove impact machine bed, regulate the centre distance of punch die to positioning disk, because this punch die is the mould that one pair of stator slot shape and a diameter of stator bore punching press complete, after single groove punching is started working, because the stator slot shape drift arranged cuts drift higher than diameter of stator bore; Therefore, stator slot shape drift must first contact material and stamp out stator slot shape, and slider of punch continues descending, and the diameter of stator bore diameter of stator bore circular arc of cutting on drift and die 3 interacts and forms punching press for the second time again, completes being separated of stator punching and rotor punching.After slide block starts return, rotor punching, under the rebound effect of the second discharging spring assembly 12, is ejected die 3, completes the work that stator slot shape waste material is separated with rotor diameter by discharging jacking block 10; Now lathe dividing spindle drives punching to rotate, and when slide block declines again, repeats above-mentioned action, until follow procedure setting stamps out stator punching.
These are only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
