Abstract
The invention discloses a method for binding a transformer iron core, which includes: firstly, cutting iron core chips which serve as raw materials, then sequentially stacking the iron core chips, clamping an iron core column and overturning and rising the iron core column; secondly, removing a center column clamping device and binding a Tenax polyester belt; thirdly, binding the other two columns of the transformer with Tenax polyester belts and then suiting the device body. According to the binding method for transformer iron core, without curing, the iron core binding has the advantages of having a short working time, high binding efficiency, big binding force of the polyester belt, high strength of extension, low cost and good economic benefits, besides, a large amount of working time is saved, the manufacturing cycle of the iron core is shortened, the operation is convenient and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of method of binding transformer iron core, belong to transformer technology field.
Background technology
At present, the general technology flow process that transformer core makes is: lamination cutting → iron core overlapping → iron core column is painted, solidification → iron core stands up → and iron core adhesion belt binding → device body suit.
This technique weak point is: need iron core column japanning and solidification, and without the drying of latitude glass adhesion belt binding, curing time is normal temperature or heat drying 24 hours.Increase cost, complicated operation, production efficiency is low.
Summary of the invention
For shortcomings and deficiencies of the prior art, the invention provides a kind of method of binding transformer iron core.
The present invention adopts following technical scheme to achieve these goals:
The method of binding transformer iron core, is characterized in that comprising the following steps:
(1), first by the cutting of raw material lamination, put folder and auxiliary clamping device well, then carry out lamination closed assembly successively, clamping iron core column, iron core column upset is stood up, and keeps iron core in one plane;
(2), first iron core column being tightened up in auxiliary clamping device gap with tightener, ensureing when removing auxiliary clamping device, iron core column keeps straight not crooked;
(3), remove the auxiliary clamping device of above-mentioned iron core column, select the Tenax polyester band of B level thermal endurance class according to drawing technological requirement, more than 3150KVA product 19mm × 1.27mm, resistance intensity: 11120N; Below 3150KVA product Tenax polyester band specification 12mm × 0.71mm, resistance intensity: 3560N; The tightening force that Tenax polyester band tightens up machine is transferred to: the tightening force of Tenax polyester band specification 19mm × 1.27mm is the tightening force of 5560N, Tenax polyester band specification 12mm × 0.71mm is 1780N, colligation Tenax polyester band of then from bottom to top packing one by one;
(4), the Tenax polyester band of above-mentioned step all the other two posts of colligation transformer successively, last device body suit.
Beneficial effect of the present invention:
1, without the need to solidification, the used time is short, and colligation efficiency is high, saves a large amount of man-hour, shortens the iron core manufacturing cycle, easy to operate, enhances productivity.
2, polyester band colligation power is large, and tensile strength is high.
3, adopt polyester band to replace without latitude glass adhesive tape, cost reduces by 50%, good in economic efficiency.
Embodiment
Embodiment: the method for binding transformer iron core, comprises the following steps:
(1), first by the cutting of raw material lamination, put folder and auxiliary clamping device well, then carry out lamination closed assembly successively, clamping iron core column, iron core column upset is stood up, and keeps iron core in one plane;
(2), first iron core column being tightened up in auxiliary clamping device gap with tightener, ensureing when removing auxiliary clamping device, iron core column keeps straight not crooked;
(3), remove the auxiliary clamping device of above-mentioned iron core column, select the Tenax polyester band of B level thermal endurance class according to drawing technological requirement, more than 3150KVA product 19mm × 1.27mm, resistance intensity: 11120N; Below 3150KVA product Tenax polyester band specification 12mm × 0.71mm, resistance intensity: 3560N; The tightening force that Tenax polyester band tightens up machine is transferred to: the tightening force of Tenax polyester band specification 19mm × 1.27mm is the tightening force of 5560N, Tenax polyester band specification 12mm × 0.71mm is 1780N, colligation Tenax polyester band of then from bottom to top packing one by one;
(4), the Tenax polyester band of above-mentioned step all the other two posts of colligation transformer successively, last device body suit.
