Description
Technical field
It the utility model is related to a kind of induction heating apparatus, more particularly to a kind of new sensing to small diameter shaft heat treatment
Heating unit.
Background technology
Sensing heating is that workpiece is put into induction coil, and intermediate frequency or high-frequency alternating current are then inputted into induction coil,
Alternating magnetic field is produced, while the sensing electric current of identical frequency is produced in workpiece.Distribution of this sensing electric current in workpiece
Be it is non-uniform, it is strong on surface, and internal very weak, to center portion close to 0, using this kelvin effect, workpiece surface can be made
It is rapid to be heated, surface temperature is risen to 800-1000 DEG C in seconds, and center portion temperature raises very little.Since sensing adds
Hot surface quenching technical is good with hardened face quality, and brittleness is small, and hardened face is not easy oxidation and decarbonization, deforms the advantages that small, institute
Process of thermal treatment is carried out with metal surface by sensing heating to be more and more widely used, for example, the surface of axial workpiece
It is heat-treated generally use induction coil heating technique.But due to the limitation of induction coil own dimensions size, induction coil it is straight
Footpath is generally bigger, to small-diameter shaft part carry out sensing heating Surface heat-treatent when, the efficiency of heating surface can be made relatively low and
Produce very big energy dissipation.And single turn load is light, can not be matched with high-frequency apparatus.Therefore, in order to improve the effect of sensing heating
Rate and the saving energy are, it is necessary to be improved the induction heating apparatus of traditional axis.
The content of the invention
In view of the above problems, the utility model device proposes that one kind installs additional between small-diameter shaft part and induction coil
Electromagnetic flux field concentrator improves the new induction heating apparatus of sensing heating efficiency.
The utility model device mainly include electromagnetic flux field concentrator, load coil, positive pole connecting plate, cathode water inlet,
Positive terminal, negative pole connecting plate, anode water outlet, negative terminal, small diameter shaft are located at the center of load coil, make
It is consistent to obtain each point heating temperature in sensing heating on small diameter shaft surface；Electromagnetic flux field concentrator is equidistant to be enclosed in outside small diameter shaft
Side, and among load coil, increase coil length, realize local afflux, improve periphery power density；
Positive pole connecting plate and negative pole connecting plate are connected with load coil respectively by welding, and positive terminal and negative terminal lead to
Welding is crossed to be connected with positive pole connecting plate with negative pole connecting plate respectively；Positive pole connecting plate and negative pole connecting plate be machined with respectively cathode into
The mouth of a river and anode water outlet, cool down load coil.
Present inventive concept is realized by following technical proposals：Small diameter shaft is located at the center of load coil；Magnetic flux
Concentrator is equidistant to be enclosed on the outside of small diameter shaft, and electromagnetic flux field concentrator is located in load coil, realizes local afflux；Just
Pole connecting plate and negative pole connecting plate are connected with load coil respectively by welding；Positive terminal and negative terminal lead to
Welding is crossed respectively with positive pole connecting plate and negative pole connecting plate to be connected；Positive pole connecting plate and negative pole connecting plate process respectively cathode into
The mouth of a river and anode water outlet, cool down load coil.
The advantages of the utility model device is brought than existing induction heating apparatus and good effect：
1st, the magnetic flux current collector between load coil and small diameter shaft, increases coil length, realizes local afflux,
Improve periphery power density.
2nd, the apparatus structure is simple, and easily operated and cost is low, highly practical.
