Description

A kind of armature, stator punching mold
Technical field
The utility model relates to mould applications, particularly a kind of for all kinds of armature stamping for electric machines, stator punching and multiple-grooved, thin wall punching parts mould.
Background technology
Armature stamping for electric machine, stator punching and multiple-grooved, thin wall punching parts mould, when trial-production or small batch, conventionally adopt two-step: first carry out punched hole punching groove, carry out blanking and punching separation, the object of using two molds to carry out stamping-out is exactly to solve because the thin problem of punching partial wall again; Directly adopt single-station die tool, punch-die part is finished behind blanking nest hole, and insufficient strength is easily burst apart, cutting edge short life is low.
If adopt two station progressive dies or high-speed punching fine blanking die mould, it is long that mould is manufactured the high cycle of difficult cost, generally when producing in enormous quantities, adopts, but also will use corresponding its effect of pressing equipment competence exertion.
Traditional punch-die has blanking nest hole, and nest hole generally expands 0.2-0.5mm around than cutting edge size, stays cutting edge length to be generally 5-7mm, and this part thin-walled place is 1.5mm, and after punch-die is done blanking nest hole, local wall thickness only has 0.5-1.1mm, during stamping-out, very easily ftractures; Traditional die has discharger nest hole, stays cutting edge length to be generally 20mm, and because hole nest is larger, the actual effective length of cutting edge reduces by half; Be only ten thousand left and right of 20-40 traditional die life.
Summary of the invention
The utility model provides a kind of armature, stator punching mold, it can directly adopt single-station die tool on common pressing equipment, solve multiple-grooved, the disposable stamping-out of thin wall punching parts, make single-station die tool there is the high-quality and high-efficiency high life, manufacture simple feature with low cost.
The technical solution of the utility model is for this reason: a kind of armature, stator punching mold, comprise upper and lower mould bases, it is characterized in that: under top mold frame, by alignment pin, be provided with loading and unloading material device, loading and unloading material device is provided with cushion block outward, loading and unloading material device has upper padding plate, under upper padding plate, by convex-concave die holder, be provided with punch-die, punch-die has stripper; Lower mold holder is provided with lower bolster, on lower bolster, by convex mould base, be provided with die, in die, by the punch-die under the corresponding upper padding plate of lower discharger, be provided with punch one, punch two, punch three, punch four, in lower mold holder, lower bolster and convex mould base, be penetrated with the corresponding punch one of a plurality of push rods, punch two, punch three, punch four.
Improvement to such scheme is: between convex-concave die holder and stripper, be provided with shock absorbing rubber.
Improvement to such scheme is: punch two is provided with a plurality of pin stop.
Beneficial effect:
The utility model mould completes stamping-out by punch-die, die, punch, and discharging part is promoted respectively the component parts of loading and unloading material device and alignment pin by dnockout parts, gets the waste material in the punch-die of through type cutting edge; By shock absorbing rubber, stripper, push billot on punch-die open; Part in the die of releasing through type cutting edge by the elastic body of lower mold holder.
Be the single-station die lamps structure adopting on common pressing equipment, solve multiple-grooved, the disposable stamping-out of thin wall punching parts, realize the effect of the grading high-precision mold of multistation, there is the high-quality and high-efficiency high life, manufacture simple feature with low cost.
The use of shock absorbing rubber between convex-concave die holder and stripper, reduces the impulsive force between mould, prevents the gouge of punch-die and the punch edge of a knife, extends its service life.
The effect of location is played in the use of pin stop.
Adopt through type punch-die, die, do not need to do nest hole, effectively cutting edge length is 20mm, and the intensity life-span all significantly improves, and punching can reach more than 1,500,000.
Accompanying drawing explanation
Fig. 1 is the main TV structure figure of the utility model.
In figure, 1 is punch-die, the 2nd, and loading and unloading material device, the 3rd, alignment pin, the 4th, cushion block, the 5th, upper padding plate, the 6th, convex-concave die holder, the 7th, shock absorbing rubber, the 8th, stripper, the 9th, push rod, the 10th, lower bolster, the 11st, convex mould base, the 12nd, die, the 13rd, lower discharger, the 14th, punch one, the 15th, pin stop, the 16th, punch two, 17th, punch three, the 18th, punch four, 19th, top mold frame, the 20th, lower mold holder.
The specific embodiment
The example providing below in conjunction with Fig. 1 further illustrates the utility model.
A kind of armature, stator punching mold, comprise upper and lower mould bases 19,20, top mold frame is provided with loading and unloading material device 2 by alignment pin 3 19 times, the outer cushion block 4 that is provided with of loading and unloading material device 2, loading and unloading material device 2 has upper padding plate 5, upper padding plate is provided with punch-die 1 by convex-concave die holder 65 times, and punch-die 1 has stripper 8; Lower mold holder 20 is provided with lower bolster 10, on lower bolster 10, by convex mould base 11, be provided with die 12, in die 12, by the punch-die 1 under the corresponding upper padding plate 5 of lower discharger 13, be provided with punch 1, punch 2 16, punch 3 17, punch 4 18, in lower mold holder 20, lower bolster 10 and convex mould base 11, be penetrated with the corresponding punch 1 of a plurality of push rods 9, punch 2 16, punch 3 17, punch 4 18.
