Motor stator provided by the utility model compound band grooving shape waste material mold, including die ontology entirely, feature
Be: the stator slot shape punch-pin 15 including being located at the die ontology has heavy type under axis hole cavity plate 22 described in lower die in jet-bedding
Rectangular Spring 25 can be supported the axis hole cavity plate 22 using its elastic force, be guaranteed with the stator concave-convex mold piece 16 same flat
Flute profile punching separation is realized in face.
The stator slot shape punch-pin 15 is with product design quantity circular array, with the stator slot shape punch retainer
11, there is gas circuit component 28 positioned at the fixed end face of each stator slot shape punch-pin 15, be located at each diameter of stator bore punch-pin
There are 4 positioning pins 3 on 20, have linear axis between the corresponding upper padding plate 9 of each positioning pin 3 and the positioning pin 3
It holds 4, have guide part 21 in 4 groups of lower dies positioned at the axis hole cavity plate 22, guarantee that activity is freely when its work.
The stator slot shape punch-pin 15 and 13 height of stator shape cavity splits is consistent, is punched in stator slot shape punch-pin 15
While also complete to be punched with the shape of stator concave-convex mold piece 16.The stator slot shape punch-pin 15, stator shape cavity plate are spelled
13 height of block is consistent, and diameter of stator bore punch-pin 20 is lower than the stator slot shape punch-pin 15 and stator shape cavity splits 13 about again
2.65~4.0 times of material thickness t, it may be assumed that first punch flute profile and rush motor stator internal diameter again.
After completing the stator slot shape and stator shape punching, upper mold is continued traveling downwardly, when downlink strength is greater than lower mold shaft
When the strength of the heavy Rectangular Spring 25 under hole cavity plate 22, the lower die axis hole cavity plate 22 also downlink is forced, is made in the stator
Diameter punch-pin 20 and 16 internal diameter of lower die stator concave-convex mold piece form shearing up and down, complete motor stator internal diameter punching, the stator
Internal diameter punch-pin 20 is inserted into the linear bearing 4 equipped with 4 positioning pins 3, provides conveniently for mold assembly and later maintenance.Described
After diameter of stator bore punch-pin 20 completes motor stator internal diameter punching, the axis hole punch-pin 23 is higher than the diameter of stator bore punch-pin 20 about
1.5~2.0 times of material thickness t follow downlink and state axis hole cavity plate 22 and realize axis hole punching, and guide part 21 is mounted in the lower die
It states and plays guiding role under axis hole cavity plate 22.
The stator shape cavity splits 13 are linked together with stator cavity splits pad 12 with screw, respectively there is 6 pieces, are in ring
Shape splicing, each stator shape cavity splits 13 are with stator cavity splits pad 12 by screw pin and the upper padding plate 9
It is connected and fixed, the upper padding plate 9 is fixedly connected with the upper die holder 10.The grading mould body also has mounted in upper and lower mould
Outer guide part guiding on seat guarantees that activity is freely when use.The stator shape cavity splits 13 in a state of excitement cut out when and institute
It states stator concave-convex mold piece 16 and forms shearing separation, the stator concave-convex mold piece 16 is spliced in a ring by 4 pieces, with the underlay
Plate 18 is fixedly connected, and the lower bolster 18 is connected and fixed with the lower die holder 19.

31 both sides of lower die cutter are symmetrical, and when work cuts off three horn scraps, 33 support of retainer plate that the material has lower die to install
It is flat, so that coiled strip when work is all around sent into steady and smooth.
Past uses single step mould (4 sets of single-stroke moulds) continuous productive process production method, and mold is mostly autonomous Design manufacture, by
Rising steadily in cost of labor causes overall cost to increase, and profit reduces, therefore changes production method, and it is imperative to improve efficiency.
It is required that manufacture and design motor stator compound band grooving shape waste material mold entirely, about 50 beats/min of punching speed.It is entirely compound that the mold belongs to thin material
Mold (material thickness 0.5mm), stock layout are that wide 2 row of material is staggered, and by waving feed appliance feeding, sufficiently improve stock utilization
And production efficiency.It is manufactured experimently by the research and development of the staff, which not only wants that qualified 8TD.660.8700 stator can be stamped out
Punching, 8TD.662.8700 rotor light two kinds of parts of circle+axis hole, and mold stable production process is reliable.The utility model at
Function reduces number of molds instead of original production mode, reduces equipment occupancy, improves production efficiency.
Rotor punching is electric machine iron core key component part, and product parts size, burr require extremely stringent, Ke Hushi
It tests requirement to laminate in the 90 ° of dislocation of special tooling, guarantees that each flute profile laminates rear flute profile and cannot have dislocation and color difference phenomenon, circularity≤
0.027, concentricity≤￠ 0.04, position degree≤0.04, according to requiring to be not difficult to find out, design difficulty of processing is all very big.Due to
Part material is thin plate strip, and feeding can all impact product with sending, have enough to meet the need etc., so several motor manufacturings at home
Enterprise is at present all using single die tool production.Thus, it is possible to reflect the mold complexity complexity.
As shown 3 show original production process, first lower section sheet stock, then rush stator outer circle, welding groove, cramp slot, circular shaft hole
With mark slot, then stator slot shape and motor stator internal diameter are rushed, then rushes rotor slot shape and axis hole key with process waste material (heronsbill)
Slot.This Sheet Metal Forming Technology, process is long, waste material (heronsbill) the red switch period of the day from 11 p.m. to 1 a.m that stator punching groove shape and internal diameter generate not only poor location,
And it is easy tooth form of damaging in the process of copying mechanically, directly affect the accuracy and size, the stability of shape of positioning.
The shown mode host visual pattern for the product in as shown 4, the mold want a punching stroke, and timesharing distribution is realized
Stator outer circle, welding groove, cramp slot, stator slot shape punching；It realizes that motor stator internal diameter is separated with flute profile waste material, and guarantees motor
Diameter of stator bore size；Realize that axis hole light circle is punched and guarantees that rotor blank is light circle.
As shown 7,8 show the utility model production technology, and with coiled strip by feed appliance is waved, the step that is swung left and right is real
The existing full multiple pressing of stator, it may be assumed that complete stator outer circle, welding groove, cramp slot, stator slot shape and motor stator internal diameter, rotor hair
Base is light circle, realizes the separation of stator slot shape waste material and rotor diameter.Rotor punching press is useless with process light circle as shown in the drawing
Material rushes rotor slot shape and axis hole keyway.This Sheet Metal Forming Technology, process is short, and the waste material that stator slot shape generates directly cuts off downward row
Out, the red switch period of the day from 11 p.m. to 1 a.m uses up round blank positioning, and this scheme accurate positioning and size shape are stablized.
Using single step mould flow line production mode, mold is more, process is tedious, and overall cost increases, product profit reduces；
And use stator compound band grooving shape waste material mold production method entirely instead, the complete compound punching press of stator profile is realized, while
Reach rotor diameter to separate with the perfection of stator slot shape waste material, ensure that a punching press of rotor light circle and axis hole, this is practical
Novel taken technical solution can not only improve production efficiency, reduce mold, and can be shortened manufacturing procedure, reduce equipment
With the occupancy of manpower, mold is also reliable and stable, greatly improves production efficiency.
