Description
Technical field
The present invention relates to a kind of electrical-coil method for dismounting, more specifically, it relates to which a kind of machine winding heat tears method open.
Background technique
Motor is widely used in industrial circle, and its structure is also relatively single, and existing electric machine structure mainly includes
Stator and rotor, rotor are located at stator interior and can be rotated around rotor.
Stator structure therein is as shown in attached drawing 1 and attached drawing 2 comprising has fixed shell 3, is equipped with silicon steel in fixed shell 3
Piece group 4 is arranged with coil windings 5 inside the silicon steel sheet group 4, after being fastened between silicon steel sheet group 4 and fixed shell 3, firstly,
In order to prevent coil windings 5 from occurring directly to contact with silicon steel sheet group 4, can pad equipped with insulating paper between the two；Secondly, in order to increase
Add the high temperature resistance of coil windings 5, insulated paint can be coated outside coil windings 5；Again, from structure, due to coil
Winding 5 is wound in silicon steel sheet group 4 by way of winding, on 3 two ends of close fixed shell of coil windings 5 are respectively
Winding 1 and lower winding 2, upper winding 1 and lower winding 2 protrude from the end of silicon steel sheet group 4 respectively.
For the motor of above structure, electrical machmary maintenance industry generallys use the cold mode torn open, the so-called cold mode torn open, i.e., first
Then the either lower winding 2 of winding 1 on sliding trackle is applied using the either lower winding 2 of lower winding 1 of the tensile machine to the other end and is drawn
Power effect, entire coil windings 5 can be disassembled from silicon steel sheet group 4；Cold to tear mode open although disassembly is quick, there is ten
Divide fatal disadvantage, i.e., there are insulating papers between coil windings 5 and silicon steel sheet group 4, and 5 lateral wall of coil windings is coated with insulation
Paint, so as to cause between coil windings 5 and silicon steel sheet group 4 there are biggish viscous force, when coil windings 5 when pulled, coil
Huge pulling force can be generated between 5 meeting of winding and silicon steel sheet group 4, gently separates silicon steel sheet group 4 with fixed shell, it is heavy then direct
Make the silicon steel sheet monomer in silicon steel sheet group 4 that separation each other occur, motor is caused to scrap.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of machine winding heat to tear method, energy open
The scrappage of motor is effectively reduced.
To achieve the above object, the present invention provides the following technical scheme that a kind of machine winding heat tears method open, including it is following
Step: Step1, tangent line: using the either lower winding of the upper winding of perching knife cutting tool sectioned coil winding, and make
Winding or lower winding select to be completely cut through between one and coil windings；
Step2, it burns line: the fixed shell in Step1 is heated；
Step3, it pulls out line: when upper winding is cut off, pulling lower winding using external tool, and make coil windings and silicon steel
Piece group is kept completely separate；Or upper winding is pulled using external tool, and make coil windings and silicon steel sheet group when winding is cut off instantly
It is kept completely separate；
Step4, it removes insulating paper: removing the insulating paper adhered in silicon steel sheet group；
Step5, it removes insulated paint: removing the insulated paint adhered on the outside of silicon steel sheet group；
