Because induction heating has efficiently, cleans, easily is automated the advantage of production, extensively applied in the heat treatment of metal processing work, the process such as rolling.Its principle generally is outside part to be heated electromagnetic induction coil to be set, and logical alternating current in it makes coil produce electromagnetic induction heat and comes heated components.For parts such as gear, bent axles, coil can also be made various corresponding complicated shapes.But in induction heating, particularly in the iron and steel of extensive, automation, serialization is produced, size, size in the middle of the very long processing work of length change often, cause powered-down often, change the coil of corresponding size, otherwise processing work can't pass through smoothly, causes operation very complicated, has reduced production efficiency.
United States Patent (USP) 4708227 and 4828227 discloses a kind of adjustable induction heater, see also shown in Figure 1, this induction heater comprises iron core 4, solenoid 2 and cylinder 3, iron core 4 is the C type, one side is provided with opening, be wound with solenoid 2 on the opening two ends respectively, opposite side is designed to a plurality of active segments, and connects by hinge 5; Cylinder 3 is connected with the two ends of the active segment of iron core 4.During use, when the limit of slab to be heated in the opening 1 thickness changes, the active segment that drives cylinder 3 drive iron cores 4 moves, and make and produce angle between the active segment, by hinge 5 distance between the opening two ends of iron core 4 is changed simultaneously, thereby the processing work that satisfies different-thickness pass through smoothly, therefore need not powered-down, more emat coil has improved production efficiency.But when powerful induction heating, when the hinge point of the iron core of this induction heater existed leakage field and iron core opening to change, the end face at opening two ends was difficult to guarantee that the steel slab surface with heating is parallel.
The utility model content
Hinge point at the above-mentioned iron core that exists in the prior art exists leakage field, iron core open end to be difficult to guarantee and the parallel shortcoming of steel slab surface that heats, the purpose of this utility model provides a kind of induction heating equipment, this device can be applicable to the processing work of any size, size, and can improve the efficiency of heating surface.
For achieving the above object, the utility model adopts following technical scheme:
Be installed with processing work in this induction heating equipment, comprise support and body, support is provided with body, and body further comprises framework, electromagnetic yoke and coil, is provided with electromagnetic yoke in the framework, is provided with coil in the electromagnetic yoke.
Described electromagnetic yoke is designed to " ∏ " type part of four symmetry, is enclosed in around the described coil, and the other end of each " ∏ " type part is provided with base plate and fixes with base plate, and base plate is provided with connecting rod; Described coil is enclosed in outside the processing work.
At least be provided with a connecting rod on the described base plate, described connecting rod one end is connected with base plate and is fixing, and an end passes framework.
Be provided with cooling water pipeline in the described base plate.
Described coil is wrapped on the processing work, and internal diameter is the minimum dimension that the production status of the processing work of maximum specification allows.
Described framework also is provided with cylinder outward, and cylinder is connected with connecting rod one end.
In technique scheme, be installed with processing work in the induction heating equipment of the present utility model, comprise support and body, support is provided with body, and body further comprises framework, electromagnetic yoke and coil, is provided with electromagnetic yoke in the framework, is provided with coil in the electromagnetic yoke.Adopt this device, simple in structure, easy to use, because coil is wrapped on the processing work, and internal diameter is the minimum dimension that the production status of the processing work of maximum specification allows.So this device is applicable to the processing work of any size, size, need not to change other coils.Because framework is provided with cylinder outward, cylinder is connected with connecting rod one end.So, can guarantee that the end face at the opening two ends of electromagnetic yoke remains close to parallel with the processing work surface all the time, thereby increase work efficiency by driving cylinder, reduce magnetic leakage, improve the heating-up temperature uniformity, improve heating quality.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 2ly, this induction heating equipment comprises support 6 and body 7, and support 6 is provided with body 7, and body 7 further comprises framework 8, electromagnetic yoke 9 and coil 10, is provided with electromagnetic yoke 9 in the framework 8, is provided with coil 10 in the electromagnetic yoke 9.Please in conjunction with shown in Figure 3, electromagnetic yoke 9 is designed to " ∏ " type part of four symmetry, adopt the silicon steel sheet or the Ferrite Material of high magnetic conduction to make, be enclosed in coil 10 around, the other end of each " ∏ " type part is fixed with base plate 11, adopts the stainless steel of non-magnetic to make, and offers cooling-water duct 12 water flowings cooling in inside, prevent base plate 11 induction heating, also can strengthen cooling by heat conduction simultaneously electromagnetic yoke 9.At least be provided with a connecting rod 13 on the base plate 11, adopt nonmagnetic stainless steel to make, connecting rod 13 1 ends are connected with base plate 11 and are fixing, and an end passes framework 8 and is connected with cylinder 3.Drive cylinder 3 (shown in Figure 2) motion, and transmit by connecting rod 13, four " ∏ " types parts that can drive electromagnetic yoke 9 move at the same time or separately, thereby regulate the distance between electromagnetic yoke 9 and coil 10, the processing work 14.Coil 10 adopts copper pipe to make, boring, but water flowing cooling.Coil 10 is wrapped on the processing work 14, according to the maximum specification of processing work 14, coil 10 is wound in the frame type structure of the minimum dimension that processing allows, and with processing work 14 near and keep certain distance.The copper pipe outer wall of coil 10 has insulating material, is provided with refractory material and cement in the coil 10 and smashes the liner that forms of knot, can prevent the infringement that 14 pairs of coils 10 of processing work of iron scale and dislocation may cause.Also be provided with cushion block 15 in the framework 8, coil 10 is placed on the cushion block 15, and cushion block 15 plays the supporting role to coil 10.
See also shown in Figure 4ly, adding man-hour, processing work 14 is passed coil 10, energising in coil 10 produces electromagnetic induction heat, and processing work 14 is heated.When the size of processing work 14, when size changes, only need to drive cylinder 3, " ∏ " type opening two ends partly that make electromagnetic yoke 9 are perpendicular to the relative motion on processing work 14 surface direction, thereby the end face at opening two ends of " ∏ " type part that makes electromagnetic yoke 9 is all the time near the surface of processing work 14 to be heated, and remain parallel with processing work 14 surfaces, thereby the electromagnetic field that coil is produced accumulates in processing work 14 surfaces, improves the efficiency of heating surface.
Induction heating equipment of the present utility model, simple in structure, easy to use, not only can prevent leakage field, and be applicable to the online production of the processing work of all size, size, need not to change other coils, the end face that can guarantee the opening two ends of electromagnetic yoke in addition remains close to parallel with the processing work surface all the time, thereby increases work efficiency, and reduces magnetic leakage, improve the heating-up temperature uniformity, improve heating quality.
