Abstract
The utility model provides a mould capable of simultaneously punching a wire slot and damping holes of a generator rotor punching sheet. The mould is characterized in that a punch head fixedly arranged on an upper fixed plate of the upper mould comprises a wire slot punch head and damping hole punch heads, wherein both the wire slot punch head and the damping hole punch heads are fixedly arranged on the upper fixed plate, the wire slot punch head is at the center while the damping hole punch heads are distributed at both sides of the wire slot punch head, and the lower mould is provided with cutting edges corresponding to the wire slot punch head and the damping hole punch heads. As the wire slot punch head and the damping hole punch heads are arranged on one mould, the mould saves the material for a set of mould and saves processing cost and can simultaneously finish punching a damping hole and a wire slot, therefore saving the time for replacing and debugging the mould, improving the work efficiency more than one time, reducing labor intensity, reducing waste resulted from mould tests, avoiding quality loss during conversion operation, and guaranteeing the rotor punching sheet quality and punching efficiency during the punching.
Description
Technical field
The utility model relates to a kind of manufacturing generator mould, especially a kind of mould towards the generator amature punching.
Background technology
Generator is a kind of the most frequently used energy conversion device, and demand is very big.One of its core component rotor is to obtain rotor punching after utilizing mould to whole sheet-metal press working, and rotor punching laminates the back and forms generator amature.The punching course of prior art stamping rotor punching is: blanking, one-shot damping hole (or one group of damping hole), one-shot wire casing.Be two separate molds wherein towards damping hole mould, the groove mould of breasting the tape, they include part of the upper die, part of the lower die and targeting part, the part of the upper die is made up of upper bolster, hard packing plate, upper mounted plate, drift, discharging spring and stripper, the part of the lower die is made up of counterdie, bottom plate, adjustment backing plate and die shoe, distinctive points: towards the damping hole mold and punching head is the damping hole drift, and the groove mould drift of breasting the tape is the wire casing drift.
At present, when finishing rotor punching with an equipment, need debugging mould twice, at first the punching out damping hole has been piled up punching, unloads towards the damping hole mould, changes breast the tape groove mould, punching out wire casing again.When finishing rotor punching with two equipment, need two cover positioning disks, need be piled up the punching of the good damping hole of punching out neatly like this, then it are forwarded to another equipment punching out wire casing.The rotor punching of existing mold processing laminates with axis hole (by dummy shaft), wire casing (by the groove rod) location, keyway orientation, after can occurring the wire casing alignment after laminating, the phenomenon that damping hole is uneven can't be squeezed into amortisseur bar, can not realize the normal assembling of generator amature.If adjust breast the tape groove with towards the damping hole operation, promptly subpunch line groove hole backlash damping hole under the prerequisite of alignment wire casing, facts have proved that the uneven situation of damping hole is even more serious.
In addition, existing less because of the damping hole size towards the damping hole mould, damping hole drift corresponding on the mould is also just less, often occurs the fracture of damping hole drift in the punching course, and it is more frequent to cause mould to be repaired.Hour owing to determine design attitude towards the damping hole mould by the damping hole of each utmost point, there is the fixing difficulty of damping hole drift in spacing between damping hole, and the counterdie cutting edge strength reduces, mould easy deformation during use and influence the problem of punching burr and precision etc.
Summary of the invention
It is a kind of simultaneously towards the mould of generator amature punching wire casing and damping hole that the purpose of this utility model is to provide, because rotor slot and damping hole are gone out simultaneously, so when wire casing is neat, damping hole must be neat, can improve the quality and the ram efficiency of punching course rotor punching, need two mold punching out rotor punching grooves, hole in the prior art, occur wire casing during the generator amature assembling when neat to solve, damping hole is uneven, can't squeeze into this technical problem of amortisseur bar.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of simultaneously towards the mould of generator amature punching wire casing and damping hole, form by part of the upper die, part of the lower die and targeting part, the part of the upper die is made up of upper bolster, hard packing plate, upper mounted plate, drift, discharging spring and stripper, the hard packing plate is contained in the heavy stand of upper mounted plate end face, its end face flushes with the end face of upper mounted plate, upper mounted plate is fixed on the upper bolster, and stripper, discharging spring are connected with upper bolster; The part of the lower die is made up of counterdie, bottom plate, adjustment backing plate and die shoe, and counterdie is fixedlyed connected with bottom plate, and bottom plate, adjustment backing plate link to each other with die shoe; Targeting part is made up of upper bolster, pilot unit and die shoe, pilot unit is located at the rear side of upper bolster, die shoe, it is characterized in that: described drift comprises wire casing drift and damping hole drift, wire casing drift and damping hole drift all are installed on the upper mounted plate, wire casing drift position is placed in the middle, and the damping hole drift is distributed in wire casing drift both sides; Counterdie is provided with and wire casing drift, cutting edge that the damping hole drift is corresponding.
Further perfect as technique scheme, for the phenomenon of avoiding occurring the fracture of damping hole drift in the punching course takes place, described part of the upper die also is provided with little guide pin bushing and the little guide pillar that connects together, and the hypomere of little guide pillar is fixedlyed connected with stripper, and little guide pin bushing is fixedlyed connected with upper mounted plate.
When on the line of symmetry of the punching utmost point tooth damping hole being arranged, described damping hole drift has odd number, the damping hole position that one of them damping hole drift and punching screw out on the utmost point tooth line of symmetry of side is corresponding, all the other damping hole drifts are symmetrically distributed in the both sides of wire casing drift, and corresponding with the damping hole position, the outside of punching utmost point tooth line of symmetry.
When the punching damping hole was symmetrical in the line of symmetry distribution of utmost point tooth, described damping hole drift was symmetrically distributed in wire casing drift both sides.
It is above-mentioned simultaneously towards the mould of generator amature punching wire casing and damping hole that the utility model provides, because wire casing drift and damping hole drift are designed on a mold, the material and the processing charges of a secondary mould have been saved, finish simultaneously towards the damping hole and the groove two procedures work of breasting the tape, the time of saved replacing, debugging mould, operating efficiency is more than doubled, reduced labour intensity, reduced the punching waste that die trial causes, avoid the mass loss that causes in the process of transfer order, thereby guaranteed punching course rotor punching quality and ram efficiency.In addition, owing to set up little guide pillar and little guide pin bushing, the technical problem of easy fracture avoids mould frequently to change, keep in repair when having solved the punching press of damping hole drift effectively.
