Embodiment
As shown in Figure 1 and Figure 2, induction diathermic furnace, mainly comprise grate, yoke 6, furnace lining 7, ruhmkorff coil 8 and water-cooling system, grate comprises upper support body 1 and lower support 2 two portions, upper support body 1 and lower support 2 are by laterally square tube, vertical square tube, vertical square tube are welded, be square frame shape slot type structure, in the slot type structure of lower support 2, be distributed with left gusset 4a and right web plate 4b, be welded with channel-section steel 5 respectively on left side gusset 4a and the right web plate 4b, and also be welded with channel-section steel in the centre of lower support 2 slot type structural base; In the slot type structure of upper support body 1, be distributed with left gusset 3a and right web plate 3b, be welded with channel-section steel respectively on left gusset 3a and the right web plate 3b; On above-mentioned five channel-section steels, be evenly distributed with yoke 6, the ruhmkorff coil 8 of hollow copper tubing coiled is integral around the outer ring of furnace lining 7, and on the whole yoke 6 that is shelved in the lower support 2, about magnetic yoke structure all was to adopt silieonized plate to cut into closed assembly after bar shaped and the punching in the past, use bolt sleeve insulation tube insulation locking again, be easy to generate destruction of insulation, cause each silieonized plate short circuit, lose the magnetic conduction effect; And yoke of the present invention 6 adopts alkali-frees not have the latitude band to tie up, needn't punching and bolt insulation locking, and each silieonized plate short circuit can not appear.Upper support body 1 and lower support 2 combination lockings make intravital yoke of upper support and the intravital yoke of lower support constitute to folder to ruhmkorff coil at 5.In addition, at the two ends of furnace lining 7 front end-plate 11 and back head 12 are installed, water inlet pipe 9 and rising pipe 10 are connected with the copper pipe of ruhmkorff coil 8, are provided with bimetallic thermometer on water inlet pipe 9 and the rising pipe 10.Both sides at upper support body 1 and lower support 2 all are equipped with case 13, wherein, have the ventilation louvre of shock wave on the side case, have the synthetic glass viewing window on the opposite side case.As Fig. 3, have cut on the front end-plate 11, correspondingly, also have cut on the back head 12.
The outward appearance of above-mentioned induction diathermic furnace is rectangular structure, and two portions up and down of grate are split insulation locking, the ruhmkorff coil 8 on the furnace lining and yoke 6 form a compactness inductor block, be installed on the grate very easily; And ruhmkorff coil 8 around be the stretching of falling the pentagon by five yokes 6 and hold and be fixed in the frame-type supporter; It is firm in structure durable, and the furnace lining 7 that prevents that can be effective produces stress deformation, reinforces the induction furnace one-piece construction; Compare with the board-like furnace shell of original cylinder-shaped steel, the complete installation process of this stove is comparatively easy, is beneficial to very much the maintenance to furnace shell induced inside coil 8 and yoke 6.On end plate 11, the end plate 12 cut is set, can effectively prevents magnet short-cut path.On water inlet pipe 9 and the rising pipe 10 thermometer is set all, monitors water temperature in real time.The ventilation louvre of case 13 1 sides plays better heat radiating effect; The synthetic glass viewing window of opposite side, the operation conditions of conveniently watching equipment.
When induction diathermic furnace is used for the workpiece heating, cold workpiece is pushed in the furnace lining 7 the front and back end closure earlier, ruhmkorff coil 8 is connected the adjustable mean frequency electric current, produce alternating magnetic field by ruhmkorff coil 8, produce induced current in the workpiece and have the loop of one's own under the action of a magnetic field, electric energy is converted into heat energy workpiece is heated.Feed water coolant in the hollow copper tubing of ruhmkorff coil 8, the ruhmkorff coil in the work is cooled off, guarantee steady running.
In sum, the present invention designs uniqueness, and the overall appearance beauty is generous, and is simple for structure, and intensity height, good rigidly can prevent effectively that furnace lining from producing stress deformation, and reinforce electric cooker structure; The installation and maintenance of equipment are very convenient, are widely used in the forging heating.
What need understand is: though the foregoing description is to the present invention's detailed explanation of contrasting; but these explanations are just illustrative to the present invention; rather than limitation of the present invention, any innovation and creation that do not exceed in the connotation of the present invention all fall within the scope of protection of the present invention.
