Description

Winding type motor electricity generator stator core apparatus for shaping

Technical field

The utility model belongs to a kind of apparatus for shaping, particularly a kind of winding type motor electricity generator stator core apparatus for shaping.

Background technology

The automobile current generator stator core is the critical component in the automobile current generator, and how its quality will directly influence the complete machine performance of generator.Domestic traditional production method is that multi-disc welding or riveted joint form after the monolithic punching press, its material mostly is common carbon steel board, because of unrelated between its sheet and the sheet, so more or less exist difference material itself or artificial between every on the material, simultaneously because pressure influence less than normal when being welded or riveting, occur the slit between the sheet of iron core and the sheet easily, these all directly influence the performance of generator; In addition, the utilance quite low (having only 20-30%) of material in punching formula stator core production method, its corner and middle part circle are all washed out.Occurred the winding type motor electricity generator stator core in recent years, its stock utilization significantly improves, but used shaping device complex structure in this winding type motor electricity generator stator core production technology, only is applicable to single variety.Iron core for different cultivars need be changed a whole set of shaping mould, required expense height, and Mold Making is long in time limit; In addition, above-mentioned shaping device after shaping iron core for once ejecting the excessive and difficult realization of needed ejecting force.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of simple in structure, be applicable to the shaping of different size iron core and required expense mould low, that changed is few and make short, the little winding type motor electricity generator stator core apparatus for shaping of required ejecting force of duration.

The utility model is achieved in that it has cope match-plate pattern and lower bolster, the cope match-plate pattern lower surface is provided with guide pin bushing, the lower bolster upper surface is provided with guide pillar, be provided with upper mould fixed plate at middle part, cope match-plate pattern bottom surface, patrix and upper padding plate are housed in upper mould fixed plate, be provided with die shoe at the lower bolster upper surface, the inner surface of die shoe is provided with boss, be provided with little guide pillar in the corresponding lug boss position of lower bolster upper surface, die shoe is provided with the die fixed cover, the die that inner surface is provided with Ka Tai is housed in the groove fixed cover, its special character is to be placed with the punch holder in die and die shoe, said punch holder bottom is provided with and the corresponding shoulder of the boss of die shoe inner surface, and shoulder is sleeved on the little guide pillar, on the punch holder, be set with material returning sleeve, be provided with through hole in corresponding material returning sleeve position, lower bolster surface, push rod is housed in through hole, said push rod bottom is equipped with top board, be connected with punch at punch holder upper surface, be installed with several cores at the punch side surface, said core is evenly distributed on the punch side surface.

The utility model has the advantages that: during for the shaping of different size iron core, only need to change die, punch, patrix, therefore, fewer, the required expense of mold exchange is low, the corresponding mould manufacturing schedule short; Pushing method has also overcome owing to once eject the difficulty of the excessive and difficult realization of ejecting force that needs for substep ejects; Can realize semi-automation by the control to hydraulic press, operating personnel only need workpiece is put into the position, start hydraulic press, and the iron core that will press again takes out and gets final product, thereby has reduced labour intensity widely, has also improved production efficiency.

Among the figure: 1-lower bolster, 2-lower bolster, the little guide pillar of 3-, 4-material returning sleeve, 5-die shoe, the 5A-boss, 6-die fixed cover, 7-die, 7A-Ka Tai, 8-patrix, the 9-upper mould fixed plate, 9A-shoulder, 10-cope match-plate pattern, 11-guide pin bushing, 12-stator core, the 13-punch, 14-punch holder, 14A-shoulder, 15-push rod, the 16-guide pillar, 17-top board, 18-upper padding plate, 19-core, the 20-shop bolt, 21-gland, 22-bolt, 23-bolt.

Embodiment

As shown in the figure, the utility model has a lower bolster 1, on lower bolster 1, be connected with lower bolster 2 by screw or pressing plate, be provided with lower bolster 2 at lower bolster 2 upper surfaces and be the guide pillar 16 of one, on guide pillar 16, be placed with cope match-plate pattern 10, corresponding guide pillar 16 positions are provided with guide pin bushing 11 on said cope match-plate pattern 10 bottom surfaces, by screw upper mould fixed plate 9 is installed at middle part, cope match-plate pattern 10 bottom surfaces, the inner surface bottom of upper mould fixed plate 9 is provided with shoulder 9A, annular patrix 8 and upper padding plate 18 are housed in upper mould fixed plate 9, on lower bolster 2, die shoe 5 is installed by screw, the inner surface of die shoe 5 is provided with boss 5A, be provided with little guide pillar 3 in the corresponding boss 5A of lower bolster 2 upper surfaces position, little guide pillar 3 can be one with lower bolster 2, by screw die fixed cover 6 is installed at die shoe 5 upper surfaces, the die 7 that inner surface is provided with card platform 7A is housed in groove fixed cover 6, cooperate for the inclined-plane between die fixed cover 6 and the die 7, said die 7 lower surfaces are placed on boss 5A upper surface, in die 7 and die shoe 5, be placed with punch holder 14, said punch holder 14 bottoms are provided with the corresponding shoulder 14A with the boss 5A of die shoe 5 inner surfaces, and shoulder 14A is sleeved on the little guide pillar 3, be set with material returning sleeve 4 at punch holder 14 outer surfaces, corresponding material returning sleeve 4 positions are provided with 3-6 equally distributed longitudinal hole on lower bolster 2, push rod 15 is housed in described through hole, said push rod 15 bottoms are equipped with top board 17 by screw, said push rod 15 tops are corresponding with material returning sleeve 4 positions, be connected with punch 13 at punch holder 14 upper surfaces by shop bolt 20 and three bolts 22, form annular chamber between the gap of patrix 8 and punch 13 and die 7, this annular chamber is stator core 12 positions for the treatment of shaping.Side surface at punch 13 is provided with several equally distributed slots, in described slot, be installed with the core 19 that matches with stator core 12 teeth shapes, with when the shaping with stator core 12 location, by bolt 23 gland 21 is installed at the upper surface of punch 13, so that core 19 is fixing.

During the work beginning, earlier stator core 12 is placed on the punch 13 of positioner, makes hydraulic press work then, moved cross beam drives patrix and is about to stator core 12 for 8 times and is pressed in the annular chamber between punch 13, the die 7, and when reaching the pressure of setting, the moved cross beam backhaul is to initial position.When stator core 12 ejects in annular chamber, by the up promotion top board 17 of the liftout tank of hydraulic press, material returning sleeve 4 makes progress and promotion iron core 12 thereby push rod 15 promotes, and it is together up to make iron core 12 drive punch 13, iron core 12 is separated from die 7 earlier, when punch 13 reaches top dead-centre (when punch holder 14 bottom shoulder 14A contact with die shoe 5 inner convex platform 5A), liftout tank continues up, iron core 12 will be separated from punch 13, liftout tank is return back punch 13 and material returning sleeve 4 and is got back to original position by deadweight, iron core 12 just can take out, whole end-of-job.
