Description
Technical field
The present invention relates to a kind of manufacturing process of enameling copper strap wire, particularly a kind of manufacturing process that is used for the fire-resistant thin dacron glass yarn sintered enameling copper strap wire of hydraulic generator.
Background technology
Because China greatly develops power industry recently, particularly hydroelectric development advances by leaps and bounds, the fire-resistant thin dacron glass yarn sintered enameling copper strap wire that hydraulic generator is used still belongs to blank at home, this electromagnetic wire needs the temperature resistant grade of high request, thin insulation thickness, high proof voltage requires and very strong mechanical property, it is to make wrapped one deck on the good enameling copper strap wire in advance, the dacron glass yarn of Hun Heing by a certain percentage, make dacron thread fusing through sintering then, terylen glass fiber and enamelled wire are fused into one and obtain good electric and mechanical property.
At present, also have only electromagnetic wire company of a few family of only a few to produce abroad, the succeeding in developing and be used for China's many places key project of our factory success.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of manufacturing process of fire-resistant thin dacron glass yarn sintered enameling copper strap wire, to fill up the blank of the fire-resistant thin dacron glass yarn sintered enameling copper strap wire that China's hydraulic generator uses.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of manufacturing process of fire-resistant thin dacron glass yarn sintered enameling copper strap wire is characterized in that, it comprises following step:
1) copper conductor is processed, made certain dimensional accuracy;
2) copper conductor is made enameling copper strap wire;
3) dacron thread, glass fiber is wrapped on enameling copper strap wire;
4) the dacron glass yarn enameling copper strap wire behind the Rao Bao is cured, sintering.
Described copper conductor by roll-daraf(reciprocal of farad) processes, and earlier through the rolling certain size of finish rolling, draws through mould then, can keep the high accuracy of copper conductor size.
Described enameling copper strap wire is the 200 grades of compound lacquer copper-clad of heat-resistant polyester imines/polyamidoimide lenticular wires.
The hot property of described enameling copper strap wire is softening, and to puncture index minimum be 380 ℃.
The main curing degree index glass transition temperature Tg of described enameling copper strap wire is minimum to be 200 ℃.
The optimal proportion of the two-layer film thickness of described enameling copper strap wire is 4: 6.
The degree of polymerization of described dacron thread is 50～80.
Optimal proportion between described glass fiber and the dacron thread is 35～45%.
Described wrapped angle is 35 °.
Described wrapped pitch is 7mm.
Described temperature of curing is 300～400 ℃, and the time of curing is 15～25 minutes.
Manufacturing process of fire-resistant thin dacron glass yarn sintered enameling copper strap wire of the present invention, roll by the copper conductor of enameling copper strap wire is used-daraf(reciprocal of farad) draws, make the size of conductor reach high accuracy, make 200 grades of compound enameling copper strap wires of heat-resistant polyester imines/polyamidoimide then, by the dacron glass yarn enameling copper strap wire cure, sintering, make the dacron thread fusing, dacron thread, glass fiber and enameling copper strap wire are fused into one, realize purpose of the present invention.
Embodiment
A kind of manufacturing process of fire-resistant thin dacron glass yarn sintered enameling copper strap wire, it comprises following step:
1) copper conductor is processed, made certain dimensional accuracy;
2) copper conductor is made enameling copper strap wire;
3) dacron thread, glass fiber is wrapped on enameling copper strap wire;
4) the dacron glass yarn enameling copper strap wire behind the Rao Bao is cured, sintering.
In the present invention, described conductor dbus cross roll-daraf(reciprocal of farad) processes; Conductor is rolled down to certain size through finish rolling earlier, passes through the stretching of mould then, one-shot forming; Because conductor enters the rolling basic forming of the preceding process earlier of mould milling train, when entering mould and draw, just very little to the stretching resistance of mould, greatly reduce wearing and tearing for mould, solved the problem of the conductor size precision fluctuation that die wear brings; Simultaneously, the conductor size before entering mould can be regulated arbitrarily by regulating rolling mill roll, can guarantee the precision of conductor size after entering mould like this, keeps the fluctuation of conductor size to be controlled in the scope of 0.01mm, is implemented in the size high accuracy of conductor.
The production of enameling copper strap wire
Since enameling copper strap wire also will be behind the wrapped dacron glass yarn through 350 ℃ about about 5 minutes high-temperature baking, but can not influence its technology indication, can not reduce crooked back paint film as puncture voltage can not ftracture, and the back paint film that stretches can not break away from etc., so it will have very high hot property; In the present invention, described enameling copper strap wire is 200 grades of compound enameling copper strap wires of heat-resistant polyester imines/polyamidoimide, its main hot property soft breakdown index is more than 380 ℃, its main curing degree index glass transition temperature Tg is more than 200 ℃, and the optimal proportion of the two-layer film thickness of described enameling copper strap wire is 4: 6.
The selection of terylen silk and glass fiber
Dacron thread melts earlier in whole sintering process and afterwards cools off the effect of playing adhesive glass silk and enameling copper strap wire, so require the terylen silk under the temperature resistant grade that guarantees electromagnetic wire, fusing point is low more good more, and require to have good levelability after the fusing, enameled sheet wire, glass fiber and dacron thread are fused into one; And these character of dacron thread depend on the size of the degree of polymerization of dacron thread, in the present invention, the degree of polymerization of described dacron thread is 50～80, optimal proportion described in wrapped between glass fiber and the dacron thread is 35～45%, make dacron thread, can make electromagnetic wire have good electrical property after glass yarn sintered, the favorable mechanical performance is arranged again.
Wrapped and sintering process
Wrapped and the sintering process of dacron glass yarn enameling copper strap wire is the finishing operation that electromagnetic wire is produced, and also is the operation of most critical; After making dacron glass yarn enameling copper strap wire sintering, have stronger tensile strength and resistance to bend(ing) energy, among the present invention, adopt eccentric mariages to roll into a ball wrapped head when wrapped, making wrapping angle is 35 °, big lay of lapping is 7mm, and has good permanent tension force effect.
Curing the stage after wrapped should make dacron thread fusing, levelling, can not dry by the fire bad dacron glass yarn enameling copper strap wire again, and among the present invention, stoving temperature is 300～400 ℃, and the time of curing is 15～25 minutes.
More than show and described basic principle of the present invention and principal character and advantage thereof.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
