Abstract
An intermediate frequency inductorium used for a flat copper wire right-angle butt welding relates to an intermediate frequency induction heating jointing technique, which essentially solves the problem of a bad heat output effect and an easy transplacement of a welding when a vacuum inner-cooling steamer dynamotor rotor loop heats up and butt welds the flat copper wire. The utility model uses a hollow square copper pipe to make the intermediate frequency inductorium, with the pipe cavity being a flag-shaped cooling canalage, and a stalloy open core is embedded on two sides which are vertical with each other of the intermediate frequency inductorium, with the open end level with the bottom surface of the hollow copper pipe. The root part of the intermediate frequency inductorium is jointed with an electricity power connecting plate, used for taking the heat on the connecting plate away when a heavy current is above 1000A. The intermediate frequency inductorium heats equally, and raises the temperature quickly with a good joint effect and the transplacement of the jointing point is smaller than 0.1mm.
Description
Technical field
The utility model relates to the Frequency Induction Heating solder technology.More particularly, be to utilize Frequency Induction Heating, the flat type copper wire that relates in the air inner-cooled turbogenerator rotor coil manufacture process is carried out the right angle butt welding.
Background technology
Before proposing the utility model, be used for the air inner-cooled turbogenerator rotor coil adds thermal weld to flat type copper wire Medium frequency induction circle, generally take two flat type copper wires by the rectilinear direction butt welding, its silicon steel sheet open core is installed on two parallel edges of Medium frequency induction circle, and the intermediate frequency power supply connecting plate curves and rectangular-shapedly is connected with the Medium frequency induction circle, and this power supply connecting plate is complicated, materials are many, and far away from cooling water pipe, radiating effect is poor, easily misplaces during the flat type copper wire butt welding.
The utility model content
Main purpose of the present utility model provides a kind of Medium frequency induction circle, solves flat type copper wire when the right angle butt welding, and the both sides, commissure are heated evenly, the temperature rise unanimity, and the butt welding of flat type copper wire right angle does not misplace.Realize that concrete technical scheme of the present utility model is: the Medium frequency induction circle of this flat type copper wire right angle butt welding, comprise the silicon steel sheet open core, interior cooled induction coil and intermediate frequency power supply connecting plate are formed, hollow side's copper pipe is made into cooled induction coil in the flag form intermediate frequency, its tube cavity is a cooling water channel, the mouth of pipe welds brazed fitting respectively, wherein water inlet pipe end connector internal diameter is little, outlet pipe end connector internal diameter is big, guaranteeing intake pressure greater than discharge pressure, with inlet tube and outlet tube perpendicular to, be that Medium frequency induction circle root weld has the intermediate frequency power supply connecting plate.Described silicon steel sheet open core is inlaid on two perpendicular right-angle sides of induction coil, its openend is concordant with the bottom surface of hollow copper tubing, the plane closely cooperates with the two sides vertical with last plane on the open slot inner face of silicon steel sheet open core and hollow side's copper pipe, simultaneously be lined with one deck micarex, then it partly repeatedly wrapped one deck alkali-free glass silk ribbon in the bottom surface of hollow side's copper pipe.Described silicon steel sheet open core is repeatedly adorned length than the band steel live width 3-5mm that is heated butt welding, and when guaranteeing eddy-current heating, magnetic field concentration is to flat type copper wire.During the utility model Medium frequency induction circle energising work, the heat on silicon steel sheet open core and the induction coil is all taken away by the cooling water of tube cavity, and self temperature is no more than 50 ℃.At the Medium frequency induction circle during to the butt welding of flat type copper wire right angle, because the induction coil working face from lenticular wire 1mm, is influenced by magnetic thrust, easily make two soldered flat type copper wire dislocation, therefore, be lined with contour ceramic block, can guarantee that flat type copper wire right angle butt welding place is upper and lower not misplace in two flat type copper wires, one side lower end.Because pottery is non magnetic material, can sensedly not heat.The utility model is with the Medium frequency induction circle of right angle butt welding, to facts have proved of air inner-cooled turbogenerator rotor flat type copper wire Corner butt joint, and right angle butt welding place homogeneous heating, temperature rise is fast, and welding effect is good, and the upper and lower dislocation of pad is less than 0.1mm.
Description of drawings
Further specify the utility model structure below in conjunction with accompanying drawing.
Accompanying drawing is the Medium frequency induction coil structures circle of band steel line right angle butt welding.
Among the figure, hollow side's copper pipe is made into flag form Medium frequency induction circle 1, silicon steel sheet open core 2 is flush-mounted on 1 two perpendicular right-angle sides of induction coil, soldered flat type copper wire 3 rectangular butt welding, place under silicon steel sheet open core 2 and induction coil 1 bottom surface and fit, contour pottery magnetic cushion block 4 fills up in two right angle flat type copper wires 3 times, misplaces when preventing weld heating.Induction coil 1 pipe inner ring is a cooling water channel, its water inlet pipe end 5 joint internal diameters are little, water outlet pipe end 6 joint internal diameters are big, to guarantee that intake pressure is greater than discharge pressure, inlet tube and outlet tube 5,6 perpendicular to, be that Medium frequency induction circle 1 root weld has intermediate frequency power supply connecting plate 7, help when logical big electric current 1000A is above, the heat because of conductive exothermal on the connecting plate 7 being taken away, guarantee that connecting plate 7 fully cools off.
The specific embodiment
The utility model adopts the hollow side's copper pipe of 10 * 10mm to make flag form Medium frequency induction circle, its pipe thickness is 1.5mm, tube cavity is a cooling water channel, water inlet pipe and titting water outlet weld brazed fitting respectively, the root of induction coil directly is welded on the copper connecting plate, the open slot of silicon steel sheet open core is flush-mounted on two perpendicular limits of induction coil, and closely cooperate with the face of hollow side's copper pipe, the thick micarex of its bottom surface pad 1mm, then the Medium frequency induction circle is partly repeatedly wrapped one deck alkali-free glass silk ribbon, open core is repeatedly adorned length than heated flat copper live width 5mm, and when guaranteeing induction, magnetic field concentration is to flat type copper wire.
