Abstract
The utility model relates to an electromagnetic induction heating device. The device comprises at least three electromagnetic induction heaters and an electric control box, wherein the electromagnetic induction heaters are arranged at regular intervals in a ring shape; and the electric control boxes are all electrically connected to the electromagnetic induction heaters. The device can heat large-scale metal workpieces, and has the advantages of high heating efficiency and even heating.
Description
Technical field
The utility model relates to a kind of heater that metal works is heated, and relates in particular to a kind of electromagnetic induction device.
Background technology
Electromagnetic induction heating is a kind of environmental protection, energy-conservation, mode of heating that efficient is high, its principle is with alternating current, after converting alternating magnetic field to by inductance coil, act on the metal works that is in the electromagnetic field, make and produce closed rotatory current (eddy current) in the metal works, the heat that is produced by rotatory current heats metal works, and metal works is sharply heated up at short notice, reaches heating purposes.
As shown in Figure 1, a kind of electromagnetic induction device of the prior art, it is by the electromagnetic induction heater 100 of a frame-type and be positioned at the electric cabinet 200 that is electrically connected with electromagnetic induction heater 100 on one side and constitute.Wherein a side of electromagnetic induction heater 100 has the yoke 101 of separable lifting.Before the heating, yoke 101 usefulness cranes are hung out, make electromagnetic induction heater 100 side direction have opening, thereby make the annular metal workpiece, can enter in the electromagnetic induction heater 100 as steel ring, bearing etc., and then yoke 101 hung back make electromagnetic induction heater 100 closures, and then metal works is heated.
At present, this electromagnetic induction device can only heat the micro metal workpiece, can't heat the above large-scale metal works of diameter 1.5m, promptly allows to heating, also can exist the efficiency of heating surface slow, heat uneven defective.
The utility model content
For this reason, technical problem to be solved in the utility model provides a kind of electromagnetic induction heater, and it can realize large-scale metal works is heated, and has the advantage of efficiency of heating surface height, homogeneous heating.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electromagnetic induction heater, it comprises electromagnetic induction heater and electric cabinet, it is characterized in that: described electromagnetic induction heater has more than three and three and equispaced setting in the form of a ring, and described electric cabinet all is electrically connected to described these three and three above electromagnetic induction heaters.
In order to realize that large-scale metal works can be hung in each electromagnetic induction heater easily, described electromagnetic induction heater has closeable yoke at the top.In preferred embodiment, the top of described electromagnetic induction heater has chute, and described yoke both sides have the slide rail that cooperates with chute.Adopt such structure, yoke just can horizontally slip at the electromagnetic inductor top, thereby realizes the switching at electromagnetic induction heater top, thereby brings convenience for large-scale metal works enters each electromagnetic induction heater from the top.
In embodiment of the present utility model, described electromagnetic induction heater has 6.
Adopt technique scheme, by the electromagnetic induction heater more than three and three is arranged to ring-type spaced apart, be exactly to adopt a plurality of electromagnetic induction heaters that large-scale metal works is heated like this, not only can improve the efficiency of heating surface, and because electromagnetic induction heater is the equispaced distribution, guarantee being heated evenly of large-scale metal works each several part, thereby overcome the technical barrier that single electromagnetic induction heater can't heat large-scale metal works.Therefore, electromagnetic induction heater of the present utility model has been realized and can have been heated large-scale metal works, and had the advantage of efficiency of heating surface height, homogeneous heating.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the structural representation of the electromagnetic induction heater of prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the electromagnetic induction heater of the utility model employing.
Among the figure:
100-electromagnetic induction heater 101-yoke 102-yoke 103-iron-core coil 104-chute 105-slide rail 106-underframe 200-electric cabinet 001-large size bearing
Embodiment
As shown in Figure 2, electromagnetic induction heater of the present utility model is the ring-type setting that the equispaced distributes by 6 electromagnetic induction heaters 100, and its each electromagnetic induction heater 100 all is electrically connected on the electric cabinet 200.During heating, the large size bearing 001 of diameter 2.5m hangs in each electromagnetic induction heater 100 from the top, and 6 electromagnetic induction heaters 100 heat large size bearing 001 simultaneously.
Owing to be that 6 electromagnetic induction heaters 100 are arranged to ring-type and simultaneously large size bearing 001 are heated, Jia Re gross power just improves greatly like this, thereby can heat large size bearing 001 apace, because 6 electromagnetic induction heaters 100 are evenly spaced apart, this makes large size bearing 001 each several part to be heated evenly again, thus the quality of the large size bearing 001 after helping heating.
In order can conveniently to hang in each electromagnetic induction heater 100 from the top with large size bearing 001, the top of this electromagnetic induction heater 100 is provided with the yoke 102 that can open and close, concrete set-up mode is to be provided with chute 104 at the top of the iron-core coil 103 on electromagnetic induction heater 100 right sides, the dual-side of yoke 102 is provided with horizontal slide rail 105, and slide rail 105 is stuck in the chute 104.By such structure, make yoke 102 to move right, thereby realize the switching of yoke 102 in electromagnetic induction heater 100 top left.During the hoisting large-size bearing, yoke 102 is removed, made electromagnetic induction heater 100 tops form opening, large size bearing can be entered in the electromagnetic induction heater.During heating, mobile again yoke 102 makes electromagnetic induction heater 100 top closures.
In the present embodiment, be to have adopted 100 pairs of these large size bearings of 6 electromagnetic induction heaters to heat.Certainly, vary in size, can adopt the electromagnetic induction heater 100 of different numbers to carry out the ring-type setting,, can adopt 3,, can adopt 8 or 9 for bigger again metal works such as metal works for point according to each metal works.
More than be exactly electromagnetic induction heater of the present utility model, by foregoing detailed description as can be seen, electromagnetic induction heater of the present utility model has been realized and can have been heated large-scale metal works, and had the advantage of efficiency of heating surface height, homogeneous heating.
But; those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order better to make those skilled in the art can understand this patent; can not be interpreted as it is restriction to this patent protection range; so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
