Description
Technical field
The utility model relates to motor stamping mould, specially motor stamping separates mold.
Background technique
Motor stamping separation mold is used to the punching of the rotor one of previous process being separated into stator punching and rotor
Punching.Motor stamping separation mold is made of upper die and lower die, and lower die (as shown in Figure 1) includes lower bolster, is equipped on lower bolster
Fixed plate and the piece punch-pin for being placed on fixed plate outer ring, the center of fixed plate are provided with location hole, and positioning hole has locating pin, positioning
It follows closely small end and location hole is interference fitted.When punching separates, by punching shaft hole sleeve in locating pin big end, after guaranteeing punching separation,
The inside and outside circle concentricity of stator punching reaches tolerance.The position precision and dimensional accuracy of locating pin influence in stator punching
The consistency (bus straightness after stator punching is repeatedly pressed) of the coaxial accuracy of outer circle, stator punching.
Above-mentioned lower die has following defects that
(1) low efficiency: every punching 20000 needs to sharpen mold, dismantles locating pin from lower die before sharpening,
Locating pin is packed into again after sharpening.Locating pin dismounting wastes time (1 hour) inefficiency.
(2) it requires high: since locating pin small end and lower die location hole are interference fit, to operator's skill requirement when dismounting
It is higher.
(3) easy to damage: repeated disassembled and assembled be easy to cause location hole to damage, and influences positioning accuracy.
(4) at high cost, the period is long: lower die location hole damage after need to process location hole.Due to the positioning after processing
Aperture increases, and causes locating pin to scrap, need to re-work locating pin.Cause cost increase and repair cycle long.
(5) size is non-adjustable: the punching that previous process piercing and blanking die is gone out, and different mould shaft pore sizes are different, depending on
Position nail dimension is unable to adjust, and is easily lost in use, and positioning nail dimension is non-adjustable.
Summary of the invention
The utility model solve motor stamping separation mold lower die in structure be especially locating pin existing for defect and
Problem, provides a kind of motor stamping separation mold, which is changed to cylindrical type locating pin for original step locating pin.
The utility model adopts the following technical scheme that realization: motor stamping separates mold, is made of upper die and lower die,
Lower die includes lower bolster, and fixed plate and piece punch-pin are equipped on lower bolster, and the center of fixed plate is provided with location hole, and positioning hole has
Locating pin；The locating pin is cylindrical body, locating pin and location hole clearance fit, is provided with bolt through-hole, lower bolster in locating pin
On be provided with screw hole, positioning hole has the spring between locating pin bottom surface and lower bolster upper surface, and bolt passes through in locating pin
Bolt through-hole and be screwed into the screw hole on lower bolster.When sharpening, it only need to be screwed down bolt, put down locating pin lower than on piece punch-pin
Face after sharpening, loosers a bolt, locating pin ejects plane on piece punch-pin under the action of the spring.
Further, locating pin upper end is equipped with chamfering, so that the adjustable positioning inclined-plane of locating pin upper end is formed, in this way,
The location dimension of locating pin changes as the size that locating pin is screwed into location hole (or exposed location hole) is different, to adapt to difference
The different punching axis hole sizes that mold is gone out.
The utility model has the following characteristics: 1. save the time, when sharpening, hold-down bolt only need to be tightened, by locating pin pressure
Enter fixed plate, sharpening finishes, and recalls to hold-down bolt, and locating pin automatically resets under the action of the spring, prepares gap with punching
After can continue to use, improve bench work efficiency 50%, while alleviating labor intensity；2. sharpen, due to not having to dismounting
Locating pin, it is of less demanding to bench skill；3. not having to dismounting locating pin when sharpening, locating pin position precision will not influence；4. fixed
Position nail does not have to repeated disassembled and assembled, and prolong the service life 2 times or more；5. locating pin positioning surface size adjustable, reduce mold repair at
This.

Specific embodiment
Motor stamping separates mold, is made of upper die and lower die, lower die includes lower bolster 1, and fixed plate 2 is equipped on lower bolster
With piece punch-pin 3, the center of fixed plate 2 is provided with location hole, and positioning hole has locating pin 4；The locating pin is 4 cylindrical bodies, fixed
4 and location hole clearance fit are followed closely in position, are provided with bolt through-hole in locating pin 4, screw hole are provided on lower bolster 1, positioning hole, which has, to be located at
Spring 5 between 1 upper surface of 4 bottom surface of locating pin and lower bolster, bolt 6 pass through the bolt through-hole in locating pin 4 and are screwed into underlay
Screw hole on plate 1.4 upper end of locating pin is equipped with chamfering, to form the adjustable positioning inclined-plane of 4 upper end of locating pin；Specific implementation
When, chamfering is 0.5 °.The lock-screw 7 being screwed on lower bolster 1 is additionally provided in locating pin 4；Bolt 6 often twists 1/4 circle, locating pin 4
Location dimension adjust 0.003mm, need to lock lock-screw 7 after adjusting size every time, prevent locating pin 4 loosen.It is fixed
Position nail 4 and the fit clearance of location hole be bilateral 0.005-0.01(such as, 0.005,0.008 ... ..., 0.01).
Such as certain motor stamping answers punch die with 5 sets, is No. 5, No. 6, No. 7, No. 8, No. 9 respectively；Splitting die has 3 sets points
It is not No. 5, No. 6, No. 7.Specific size is as follows:
No. 5 splitting dies can only punching 6, the punching of No. 8 multiple punch die punching out as can be seen from the above table；No. 6 separation stampings
The punching that system 5 multiple punch die punching go out；The punching that No. 7 splitting die punching 7 multiple punch die punching go out.The logical of mold is caused in this way
It is poor with property, it makes troubles to production.And in use splitting die locating pin due to abrasion size it is overproof after can only scrap
Again brand-new considerably increases the maintenance cost and maintenance cycle of mold.
Reach the cooperation requirement that the same locating pin is able to satisfy not coaxial aperture size, locating pin can be positioned to surface processing
Tapering (chamfering), the cooperation that thus can satisfy certain size range (punching size φ 90.00 --- φ 90.035) are wanted
It asks.Punching axis hole be 90.035 punching when, rotational positioning nail 4 among hold-down bolt 6, spring 5 effect under locating pin 4 to
Upper movement fastens lock-screw 7 when reaching requirement with shaft hole matching gap, can carry out punching.Punching axis hole is φ
When 90.00 punching, lock-screw 7, the hold-down bolt 6 among rotational positioning nail 4, the locating pin 4 under the effect of spring 5 are first unclamped
It moves downward, when reaching requirement with shaft hole matching gap, lock-screw 7 is fastened, punching can be carried out.In this way, locating shaft
(nail) can meet φ 90.00 --- any size between φ 90.035.
