Description
Technical field
The invention belongs to motor apparatus field, more particularly to it is a kind of undamaged to traction motor cage rotor punching
Sliver method for dismounting.
Background technology
AC frequency conversion traction electric machine as prime mover of vehicle traction be in the world the 1980s grow up
Advanced traction technique.It is developed rapidly with very significant good characteristic in moral, day, Fa Deng developed countries, is taken quickly
For traditional DC traction motor.
The rotor of locomotive AC traction motor typically uses squirrel-cage sliver, end ring welding structure as closed-loop path,
To produce electric current, and then can be with output torque in the presence of stator field.
The vibration of the rail track of locomotive operation is general all larger, locomotive longtime running under vibration, alternating current traction
Be easiest to break down at the end ring sliver assembling of rotor, gone out in end ring, sliver, end ring and sliver weld
Existing crackle even ftractures.It is a difficult point that best reparation how is carried out to failure rotor end ring sliver.
In order to avoid occurring the fatigue fracture of end ring sliver, wholly or partially wedge is taken in the part of core packet to sliver
Tight processing mode.However, when crackle occurs for AC traction motor rotor bar, end ring or fracture needs to change, will
Sliver, after especially being taken out by the sliver after tensioner, it is difficult to ensure that rotor core is not damaged, so whole rotor core is just
Have to destroy.And be also possible in the process of dismounting iron core by rotating shaft surface tear, waste whole rotor.Such as early stage
Find after directly sliver is knocked out with copper hammer, rotor slot can be caused axially because of the reaction force that hammer is tapped
Zigzag is presented in core stamping, and core stamping is seriously damaged.And when dismantling core stamping, imprudence can cause rotating shaft table again
Face is scratched, and is ultimately resulted in whole rotor and is all scrapped.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of undamaged to traction motor cage rotor punching lead
Bar method for dismounting, can take out the sliver for having crackle or being broken, and the even whole rotor core of rotor core can
Not by any destruction, and after only rotor core simply need to be cleaned, new end ring sliver just can be used directly and is welded again
Connect, to repair whole rotor.Maintenance time is not only reduced to the full extent, and maintenance cost is also reduced to the full extent.
Solve a kind of to the undamaged sliver of traction motor cage rotor punching in the present invention of above technical problem
Method for dismounting, it is characterised in that：It is a kind of to the undamaged sliver method for dismounting of traction motor cage rotor punching, its feature exists
In：
Including above step：
（1）Prepare the rotor for needing to repair, and cleaned out；
（2）The sliver of non-tensioner in rotor is extracted out by hand, it is impossible to which the sliver of extraction stays put；
（3）The end ring at sliver two ends on rotor is removed；
（4）The sliver that can not be extracted out is processed with cutter, i.e., entered with cutter from rotor slot, on sliver top
A sulculus is opened from top to down；
（5）Sliver top sulculus two ends are stepped up with fixture, the part that sliver top is contacted with rotor slot gap is occurred,
Reusing tooling device, axially continuous traction comes out by sliver, you can.
The small well width ＜ rotor width of rebate of sliver, to ensure that process tool is not contacted with rotor core.
The sliver sulculus depth scale is the 1/5-1/3 of whole sliver.
In the step（3）Or step（4）One manhole of processing of middle sliver upper end, is tied up to using tooling device and led
The hole of bar end, by sliver, axially continuous traction comes out, and more convenient operation is easy.
The through hole is located at the end position that sliver exposes iron core.
The present invention is directed to sliver in rotor slot by tensioner, and this patent provides a kind of reverse thinking, keeps rotary cutter
The contactless state with rotor core, the sliver of tensioner is relaxed, and just can be so relatively easy to it from rotor slot
Pull out, without damaging iron core.The iron core is re-started after the welding of end ring sliver and can be continuing with.Not only to the full extent
Maintenance time is reduced, maintenance cost is also reduced to the full extent.

Embodiment
Below by way of example, the present invention is further illustrated, and its raw material can purchase in market：
Embodiment 1
It is a kind of to the undamaged sliver method for dismounting of traction motor cage rotor punching, including above step：
（1）Prepare the rotor for needing to repair, and cleaned out；
（2）By in rotor non-tensioner sliver by hand extract out, it is impossible to extraction or limit-up sliver stays put；
（3）Respectively between sliver two ends end ring and rotor pressing ring, and a face is selected to carry out close to the end of end ring
Processing, the end ring at sliver two ends is removed.
（4）Rotor after being handled more than is placed on special tooling platform, with cutter is to tensioner or can not extract out
Sliver be processed, i.e., open a sulculus on sliver top, cutter enters from rotor slot, and sulculus is opened from top to down；Lead
The small well width ＜ rotor width of rebate of bar, to ensure that process tool is not contacted with rotor core, sliver sulculus depth scale is whole
The 1/5 of individual sliver, if desired working depth is deeper, can repeatedly be realized by processing.An aperture is opened at sliver end simultaneously.
（5）Sliver top sulculus two ends are stepped up with fixture, the part that sliver top is contacted with rotor slot gap is occurred,
The hole that tooling device ties up to sliver end is reused, axially continuous traction comes out by sliver.One in the sliver upper end
One manhole of end processing.
The saving time can specifically save more than 5 hours, if rotor or iron core are damaged, the saving time can not calculate.With
Method for dismounting in the present invention is almost without scrappage, and repairing significantly reduces cost.An iron core is thousands of in general, quite
