Abstract
The invention relates to a method for manufacturing micro-motor stator and rotor punching sheets and a mould specialized for punching of the stator punching sheet. The method for manufacturing the micro-motor stator and rotor punching sheets comprises the steps that notching of the loaded stator sheet is completed in one step; and the rotor punching sheet is positioned by an internal circle, and all the rotor grooves, axle holes, and groove keys and balance keys of the axle holes are punched again. The mould specialized for punching of the stator punching sheet comprises a lower mould base and an upper mould base which is flexibly connected via a guide post. The upper mould base is provided with a mould handle, an upper mould plate, an upper backing plate and an upper fixing plate from the top to the bottom in turn. The left and right of the bottom part of the upper mould base are respectively provided with a concave mould and an upper material unloading plate. The middle of the upper mould base is provided with, from the top to the bottom in turn, a hitting bar, and an upper backing plate and a material hitting rod which are arranged in the cavity of the upper mould plate. The upper part of the lower mould base is provided with a material holding plate, a lower material unloading plate and a concave-convex mould from the left to the right respectively, and the lower part is provided with a lower backing plate and an axle hole convex mould from the top to the bottom in turn. With application of the method and the mould, advantages of less working process and high productivity can be realized.

Ii, rotor punching are located with inner circle, rush sunk key and the balance key of whole rotor, axis hole and axis hole again.
Realize making the stator punching stamping-out particular manufacturing craft in electrical micro-machine stator and rotor punching method described in claim 1, it upper bolster comprising die shoe and be flexibly connected by guide pillar;
Described upper bolster is provided with die shank, cope match-plate pattern, upper padding plate, upper mounted plate from top to bottom successively, bottom described upper bolster, left and right is respectively provided with die and loading and unloading material plate, be provided with successively from top to bottom in the middle of described upper bolster be arranged between die shank and cope match-plate pattern beat excellent, be located in cope match-plate pattern cavity and re-pack and be arranged in upper padding plate, knockout rod between upper mounted plate and die; Described die shoe top is respectively provided with very flitch, lower stripper and concave-convex mold from left to right, and bottom is provided with lower bolster, axis hole punch from top to bottom successively.
Further setting as such scheme: described guide column sleeve is located at die shoe, is provided with packing ring bottom guide pillar and is equipped with lining between guide pillar bottom and die shoe.
Further setting as such scheme: described concave-convex mold is connected with concave-convex mold fixed head, is provided with little guide pin bushing in this concave-convex mold fixed head, is socketed with little guide pillar in little guide pin bushing.
The invention has the beneficial effects as follows: 1, operation is few, productivity ratio is high.New departure two procedures, namely blanking stator piece rushes shape and rotor sheet rushes shape, and productivity ratio comparatively three process improves 33%;
2, flute profile is neat.Complete the internal-and external diameter of stator piece and the punching of flute profile with a procedure, decrease position error, flute profile is neat.
3, stator and rotor slice is separated.Employing polyurethane rubber is cut out, and the transmission of exerting oneself completes.
4, sharpening is convenient, have employed detachable side guide pillar guiding, removes guide pillar, grinding cutting edge, very convenient.
5, discharging is reliable.Mould have employed little guide pillar guiding, and device for discharging flexible movements are reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of unique stator punching blanking die.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
