Abstract
The invention provides a uniform induction heating device for surface of a tubular or columnar object, which comprises a tubular or columnar object, a hollow-shaped insulating sleeve and an electromagnetic induction heating unit, wherein the electromagnetic induction heating unit further comprises a heating coil and a plurality of magnetic flux concentrators; after fixedly arranging the tubular or columnar object on the hollow-shaped insulating sleeve, the electromagnetic induction heating unit is coated outside the insulating sleeve; subsequently, the electromagnetic induction heating unit can generate the eddy current on the surface of the tubular or columnar object for the electromagnetic effect; the magnetic line direction is limited by means of a magnetic block, and the heating efficiency is promoted, so that the tubular or columnar object is uniformly and quickly heated; the heat energy is not easy to disperse by the insulating sleeve; accordingly, the heating efficiency is promoted, and the heat dispersion is reduced.
Description
Technical field
The present invention relates to a kind of tubulose or columnar objects surface uniform induction heating equipment, refer to that one utilizes magnetic inductive block limit magnetic line of force direction and promote electromagnetic induction efficiency especially, then to tubulose or the columnar objects generation vortex flow of sense magnetic material, device that is even, Fast Heating is produced.
Background technology
Plastic cement injection/extrusion molding adds man-hour, after the barrel of plastic filling pipe shape or column, extrude in mould again, and this barrel is generally a kind of resistant to elevated temperatures tubulose or columnar objects (hereinafter referred to as object), rely on this object continuous heating, make the plastics in this object in molten pulpous state, to inject in the sprue gate of mould smoothly, and for keeping steady flow, avoid the too early cooling forming of molten pulpous state plastics, therefore, before plastic injection/extrusion molding, must to this heating article continuous heating to predetermined temperature, the sustainable maintenance of plastics is made to melt pulpous state, so that really, cooling forming is again flowed to after in die cavity swimmingly by this object, and be not only used in plastic cement injection/extrusion molding, use mould molding processing procedure such as aluminium alloy casting, magnesium alloy cast all to adopt the identical practice at other.
But, the heater that existing extrusion/Jet forming machine uses is generally resistive heating device with low cost, this resistive heating device comprises a power supply unit, one electrical resistance heater coil and one can the heating object part of accommodating plastics, the conducting metal material that this electrical resistance heater coil analyses heat primarily of height is made, metal guide electrolysis pyrogen is utilized to manage, when electric current is by this electrical resistance heater coil, electric energy is converted into heat energy by the metal material that height analyses heat, so, to this heating object part Fast Heating, conduct heat inner to heating object part in the mode of radiation or conduction again, make the plastic melt of heating object part inside for molten pulpous state, and to make after in plastics energy smooth flow to die cavity cooling forming again, resistive heating device unitary construction is simple, with low cost, but its shortcoming is that heating is uneven, heat energy only can follow coil relative placement position to transmit, heating object part is caused to be positioned at the portion temperature of electrical resistance heater coil high, heating object part is not in the part of heater coil, and then temperature is lower, and produce heating object part surface temperature non-uniform phenomenon, separately, the efficiency that electrical resistance heater coil converts electric energy to heat energy is not good, compare down, must at substantial electric energy, heating object part could be heated up and reach the temperature of institute for heating.
Secondary, the heater that another existing extrusion/Jet forming machine uses, as shown in TaiWan, China certificate book number No. M365253 " the material pipe heating configuration of extrusion/Jet forming machine " Patent Case (hereinafter referred to as First Case), it comprises the material pipe storing plastics to be heated, one can be energized produces heat and to the heater coil and that heats of material pipe in order to supply the power supplier of heater coil power supply, when this power supplier transmission current is to heater coil, and this heater coil produces vortex flow because of electromagnetic induction in material tube-surface, and this material pipe itself produces heat energy because of impedance, therefore, material pipe and inside thereof are heated, separately, in the outside coated resistance to guncotton of this heater coil, accordingly, the heat that effectively can completely cut off material pipe spills into external environment condition, and significantly can promote the efficiency of heating surface to material pipe and plastics, so, this First Case utilizes electromagnetic induction principle, vortex flow and then heating are produced to material pipe, the more existing resistive heating device of its efficiency of heating surface is good, but the magnetic line of force that the heater coil of this First Case produces is Arbitrary distribution, and there are most magnetic line of force loops, the magnetic direction of these described magnetic line of force loops is without unified direction, therefore, cannot to utilize these described magnetic lines of force most effectively, and it is all different to produce vortex flow value to material each place of tube-surface, heater coil layout density higher position, as easy as rolling off a log cause surface and material pipe internal temperature too high, and heater coil layout density lower, otherwise then, and the shortcoming causing overall heating uneven.
Again, the heater that another existing hot runner uses, as shown in TaiWan, China certificate book number No. M280908 " hot runner heater coil steps up structure " Patent Case (hereinafter referred to as the second case), it consists predominantly of a hot runner body, one fixture, one heater coil, one lasso, and a collar, hot runner body locks by its fixture, and heater coil is sheathed on hot runner body appearance, and lasso is placed in the appearance of heater coil again, hot runner body is heated by electromagnetic induction by means of heater coil, and there is excessive expansion phenomenon when having prevention heater coil concurrently because expanding with heat and contract with cold, make to produce between the heating tube of heater coil and hot runner body without adding temperature gap, to promote heating effect, but this heater coil also uses the produced magnetic line of force for Arbitrary distribution, also the disappearance of First Case is had, cannot to utilize these described magnetic lines of force most effectively, and the shortcoming causing overall heating uneven.
Because above-mentioned existing various heater has respectively, heating is uneven, the efficiency of heating surface is not good and the problem such as the easy dissipation of heat transfer, and we inventor is specially studied for surface uniform induction heating equipment and improves, and has the present invention to come out.
