Abstract
The present invention discloses a method for manufacturing electromagnetic wires. The method for manufacturing electromagnetic wires can manufacture finished products by processing raw material with wire drawing, cleaning, taking up, softening, paying off, cleaning, drying, powdering, solidifying and taking up in order.
Description
Technical field
The invention discloses a kind of production method of electromagnetic wire, belong to the electromagnetic material production technical field, especially relevant with the production method of electromagnetic wire.
Background technology
Electromagnetic wire is one of major product of electromagnetic product, and the coil windings that is mainly used in electric equipment products such as transformer, instrument transformer, motor, generator is used.The production method of existing electromagnetic wire is to produce the raw material of electromagnetic wire through wire drawing → cleaning → take-up → softening → unwrapping wire → japanning → oven dry → take-up → finished product.The method of this traditional mode of production electromagnetic wire is wasted raw material, contaminated environment aborning; In use there is certain defective in the electromagnetic wire of producing in this way (enamelled wire): the one, and heatproof is lower, generally below 130 ℃; The 2nd, it is poor to insulate, and the insulation adhesive rate is at 20%-27%, and use is restricted.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of electromagnetic wire, can make the insulation adhesive rate reach 80%-90% at the production electromagnetic wire in this way, not only can economize in raw materials, but also free from environmental pollution, the electromagnetic wire good insulation preformance that utilizes this method to produce can anti-high temperature more than 180 ℃.
Taked following production method for realizing purpose of the present invention:
Raw material → wire drawing → cleaning → take-up → softening → unwrapping wire → cleaning → oven dry → powder → curing → take-up → finished product.
In the production method of the present invention powder both can be that powder in electrostatic spraying, also can be static sulfuration bed powder, can also be that powder is being immersed in sulfuration.
Curing temperature in the production method of the present invention is between 180 ℃-260 ℃, and be 8-15 minute curing time.
The used powder of the present invention is an existing insulating powder with the preparation of insulating material such as epoxy resin, polyester on the market.
Because the present invention using the enamelling process in the electromagnetic wire production method instead powder craft, powder evenly, do not have water clock, a no noxious gas emission; When producing electromagnetic wire, not only can economize in raw materials, but also free from environmental pollution; Curing temperature height when solidifying the electromagnetic wire insulating barrier in this way, generally more than 260 ℃, therefore, the electromagnetic wire of Sheng Chaning can anti-high temperature more than 180 ℃ in this way.
Specific embodiments
Powder in electrostatic spraying in the production method of the present invention, be in electrostatic spraying that powder is indoor to carry out, powder equipment (as HV generator, spray gun etc.) with existing electrostatic spraying and make powder belt static, after the backguy oven dry in this production method, the powder chamber through electrostatic spraying and can even static powder, be cured after powder.
Static sulfuration bed powder be in static sulfuration bed, to carry out,, with powder boiling and static electrification the backguy oven dry after the static vulcanizing chamber can powder by even static, is cured after powder with HV generator.
It is to carry out in sulfuration bed that powder is being immersed in sulfuration, will heat to 160 ℃-190 ℃ after the backguy oven dry, through vulcanizing chamber can be even powder, be cured after powder.
The used HV generator of the present invention, spray gun, static sulfuration bed etc. all are existing products on the market.
Embodiment 1
The wire drawing diameter of learning from else's experience is that the backguy oven dry of 1.2mm powder after the powder chamber in electrostatic spraying, is cured after powder, and curing temperature is 180 ℃; 8 minutes curing times, enter down the road production process after the curing.
Embodiment 2
The wire drawing diameter of learning from else's experience be 2.1mm the backguy oven dry after static sulfuration bed powder, be cured after powder, curing temperature is 210 ℃; 10 minutes curing times, enter down the road production process after the curing.
Embodiment 3
The wire drawing diameter of learning from else's experience be the backguy oven dry of 4.0mm after the sulfuration bed is immersing powder, be cured after powder, curing temperature is 260 ℃; 15 minutes curing times, enter down the road production process after the curing.
Claims (1)
1. the production method of an electromagnetic wire, comprise " wire drawing → cleaning → take-up → softening → unwrapping wire → cleaning → oven dry → powder → curing → take-up " step, it is characterized in that, described powder step is that the powder that will comprise epoxy resin and polyester realizes that by electrostatic spraying or static sulfuration bed the powder curing temperature of powder is between 180-260 ℃.
