Abstract
The utility model relates to a profile magnetic yoke. The magnetic yoke is one of the main parts of the coreless induction furnace and melting furnace, and is the important part for constraining the pass of the induction coil magnetic circuit and reducing the leakage of the magnetic field magnetic force line. The existing magnetic yoke structure is rectangle, and its matching to the coil external diameter is in linear type, which has unreasonable matching, large leakage, low efficiency and the like problems. A profile magnetic yoke includes a silicon steel sheet, a stainless steel plywood, stainless steel waterway boards, water nozzles and a stainless steel arc plate, wherein, the stainless steel arc plate is provided at the back face of the profile magnetic yoke to weld with the stainless steel plywood at both sides; the stainless steel waterway boards and water nozzles are provided at both sides of the profile magnetic yoke. The utility model has beneficial effects of tight matching, small leakage, good structural rigidity, and stainless steel waterways welded at both sides and water nozzles welded at both ends for cooling magnetic yoke, improving working conditions, facilitating the production, and reducing the maintenance work of the magnetic yoke.
Description
Technical field
The utility model belongs to the coreless-type induction furnace technical field, relates to a kind of profiling yoke.
Technical background
Yoke is one of critical piece of not being in the mood for by induction heater and smelting furnace, is that constraint energising induction coil magnetic circuit passes through, and reduces the vitals that magnetic field magnetic line leaks.Existing magnetic yoke structure is that the cooperation of cuboid and coil outer diameter is a linear pattern.Problems such as existence cooperates unreasonable, and leakage field is big, and efficient is low.
The utility model content
The purpose of this utility model is to provide a kind of cooperation tight, and leakage field is little, and the rigidity of structure is good, has made things convenient for the profiling yoke of making.
For achieving the above object the technical solution adopted in the utility model:
A kind of profiling yoke is characterized in that: described profiling yoke comprises silicon steel sheet, stainless steel clamping plate, stainless steel arc plate; The radian of described stainless steel arc plate is with identical with the coil outer diameter radian that cooperates installation; Its both sides and the welding of stainless steel clamping plate are provided with silicon steel sheet in it, constitute the profiling yoke.
The both sides of above-mentioned profiling yoke are provided for cooling off the stainless steel water route plate and the water nozzle of yoke.
Between above-mentioned profiling yoke and the coil insulating barrier is set.
The beneficial effects of the utility model:
1, identical with the coil outer diameter radian that cooperates installation, cooperate closely, leakage field is little, and the rigidity of structure is good;
2,, improved the utilization rate of silicon steel sheet greatly with perforate cancellation on the former silicon steel sheet;
3, both sides are welded with the stainless steel water route, and two ends are welded with water nozzle, are used to cool off yoke, have improved condition of work;
4, make things convenient for making, reduced the maintenance work of yoke.
Description of drawings
Fig. 1 is traditional magnetic yoke structure schematic diagram;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Problems such as referring to Fig. 1, existing magnetic yoke structure is that the cooperation of cuboid and coil outer diameter is a linear pattern, exists cooperation unreasonable, and leakage field is big, and efficient is low.
Referring to Fig. 2, the utility model is made up of silicon steel sheet 1, stainless steel clamping plate 2, stainless steel water route plate 3, water nozzle 4, stainless steel arc plate 5; The radian of described stainless steel arc plate 5 is with identical with the coil outer diameter radian that cooperates installation; Its both sides and 2 welding of stainless steel clamping plate are provided with silicon steel sheet 1 in it, constitute the profiling yoke.Be provided for cooling off the stainless steel water route plate 5 and the water nozzle 4 of yoke in the both sides of profiling yoke.Insulating barrier also is set between profiling yoke and the coil.
The profiling yoke at first has a profiling mould, make the radian of stainless steel arc plate 5 must be consistent with the outer radian size of coil, after silicon steel sheet 1 is cut out well, on mould, stack up, fixed-type together with the stainless steel clamping plate 2 of both sides, with the stainless steel arc plate 5 at the yoke back side and stainless steel clamping plate 2 welding of both sides, burn-on by stainless steel water route plate 3 and water nozzle 4 in both sides then, forms the profiling yoke again.Add insulating barrier at itself and coil centre during general assembly, both are installed as one.
