An adopted single-station die structure achieves one-time punching of multi-groove and thin-wall punching parts, the effect of a multi-station progressive high-precision die is achieved, the motor armature and stator punching die has the advantages that high quality and high efficiency are achieved, service life is long, manufacturing is easy and cost is low, strength is substantially improved, the service life is substantially prolonged, and the number of punched pieces can be large than 1.5 million.
Description
Technical field
The present invention relates to mould applications, particularly a kind of for all kinds of armature stamping for electric machine, 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, usually two-step is adopted: first carry out punched hole punching groove when trial-production or small batch, carry out blanking and punching separation again, the object using two molds to carry out stamping-out is exactly solve because of the thin problem of punching partial wall; Direct employing single-station die tool, after blanking socket bore is finished in punch-die local, insufficient strength is easily burst apart, cutting edge short life is low.
According to two station progressive dies or high-speed punching fine blanking die mould, then the Making mold difficulty cost height cycle is long, generally adopts when producing in enormous quantities, but also will use corresponding its effect of pressing equipment competence exertion.
Traditional punch-die has blanking socket bore, and socket bore generally expands 0.2-0.5mm than around Blade dimensions, stays land length to be generally 5-7mm, and this part thin-walled place is 1.5mm, and after punch-die does blanking socket bore, local wall thickness only has 0.5-1.1mm, very easily ftractures during stamping-out; Traditional die has discharger socket bore, stays land length to be generally 20mm, and because hole nest is comparatively large, the actual effective length of cutting edge reduces by half; Be only 20-40 about ten thousand traditional die life.
Summary of the invention
The invention provides a kind of armature, stator punching mold, it directly can 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 have the high-quality and high-efficiency high life, manufacture feature simply with low cost.
Technical scheme of the present invention 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, be provided with loading and unloading material device by alignment pin, cushion block is provided with outside loading and unloading material device, loading and unloading material device has upper padding plate, be provided with punch-die by convex-concave die holder under upper padding plate, punch-die has stripper; Lower mold holder is provided with lower bolster, lower bolster is provided with die by convex mould base, be provided with punch one, punch two, punch three, punch four by the punch-die under the corresponding upper padding plate of lower discharger in die, run through in lower mold holder, lower bolster and convex mould base and have multiple push rod corresponding punch one, punch two, punch three, punch four.
The improvement of such scheme is: between convex-concave die holder and stripper, be provided with shock absorbing rubber.
The improvement of such scheme is: punch two is provided with multiple pin stop.
Beneficial effect:
Mould of the present invention completes stamping-out by punch-die, die, punch, and discharging part is promoted the component parts of loading and unloading material device and alignment pin respectively by dnockout parts, get the waste material in the punch-die of through type cutting edge; Billot on punch-die is pushed open by shock absorbing rubber, stripper; The part in the die of through type cutting edge is released by the elastic body of lower mold holder.
Be the single-station die lamps structure adopted 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 to there is the high-quality and high-efficiency high life, manufacture feature simply 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, extend 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 socket bore, effective land 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 present invention.
In figure, 1 is punch-die, and 2 is loading and unloading material devices, and 3 is alignment pins, and 4 is cushion blocks, 5 is upper padding plates, and 6 is convex-concave die holders, and 7 is shock absorbing rubbers, and 8 is strippers, 9 is push rods, and 10 is lower bolsters, and 11 is convex mould bases, 12 is dies, and 13 is lower dischargers, and 14 is punch one, 15 is pin stop, and 16 is punch two, and 17 is punch three, 18 is punch four, and 19 is top mold frame, and 20 is lower mold holders.
Detailed description of the invention
The present invention is further described for the example provided below in conjunction with Fig. 1.
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, cushion block 4 is provided with outside 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, lower bolster 10 is provided with die 12 by convex mould base 11, be provided with punch 1, punch 2 16, punch 3 17, punch 4 18 by the punch-die 1 under the corresponding upper padding plate 5 of lower discharger 13 in die 12, run through in lower mold holder 20, lower bolster 10 and convex mould base 11 and have the corresponding punch 1 of multiple push rod 9, punch 2 16, punch 3 17, punch 4 18.
Shock absorbing rubber 7 is provided with between convex-concave die holder 6 and stripper 8.

Mould adopt upside-down mounting, in go out part form.
Mould drives punch-die 1, die 12, punch 1, punch 2 16, punch 3 17, punch 4 18 to complete stamping-out by slider of punch; Discharging part is promoted the component parts of loading and unloading material device 2 and alignment pin 3 respectively by dnockout parts, get the waste material in the punch-die 1 of through type cutting edge, push billot on punch-die 1 open by shock absorbing rubber 7 stripper 8, released the part in the die 12 of through type cutting edge by counterdie elastic body.
Structural behaviour.
Mould adopts punch-die 1, the die 12 of through type cutting edge, and punch-die is without blanking socket bore, and die, without discharger socket bore, ensures that effective land length is 20mm, and strengthening punch-die, strength of concave mould, increase die life, reduces Mould Machining difficulty.
