Abstract
The utility model relates to a heat treatment induction heating device for non-uniform diameter and non-uniform thickness shaft type parts, which comprises a quenching heating device and a tempering heating device; wherein, the quenching heating device comprises a first intermediate frequency induction heating furnace and a second intermediate frequency induction heating furnace; a induction heater in the second intermediate frequency induction heating furnace is provided with a heat-resistant steel uniform temperature cylinder; the workpiece to be heated are arranged in the heat-resistant steel uniform temperature cylinder. After the workpiece is heated rapidly to a certain temperature in the first intermediate frequency induction heating furnace, the workpiece is put into the heat-resistant steel uniform temperature cylinder in the second intermediate frequency induction heating furnace for uniform temperature heating. The utility model is particularly applicable to heat treatment of axle body of heavy-duty automobile and has the advantages of high heating quality, energy saving and high production efficiency.
Description
Technical field
The utility model belongs to induction heating technique, particularly a kind of thermal treatment induction heating device of non-wall thickness axial workpiece such as isometrical and non-.
Background technology
The axletree axis body is the major part of heavy-duty car, and big, the Heavy Weight of its body belongs to non-wall thickness axial workpiece such as isometrical and non-.At present, domestic axletree quenches and mainly takes the traditional technology of well formula resistance furnace heating, and tempering is also carried out in resistance furnace.The rate of heating of this type of heating is slow, and production efficiency is low, easy oxidation and decarbonization, and the electric energy that expends is many, and is difficult for realizing mechanize and automatic production; In addition, the annual suspender that is consumed is also very many, substitutes existing axletree axis body heat-treatment heater so production unit is badly in need of a kind of novel heating installation.Induction heating has the advantage that rate of heating is fast, efficient is high, but the axletree axis body is non-wall thickness structure such as isometrical and non-, the shape and size of its section change along axis, its intermediary main part is square hollow section in addition, heat the wall thickness axial workpiece such as non-isometrical and non-of similar axletree axis body according to the Frequency Induction Heating mode of routine, be difficult to reach even diathermal purpose.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of production efficiency height, save the thermal treatment induction heating device of the energy and diathermanous uniformly non-wall thickness axial workpiece such as isometrical and non-.
The technical scheme that addresses the above problem is: the thermal treatment induction heating device of the wall thickness axial workpiece such as non-isometrical and non-that is provided, comprise quenching heating unit and tempering heating unit, special feature of the present utility model is: the quenching heating unit comprises first Medium Frequency Induction Heating Furnace and second Medium Frequency Induction Heating Furnace, wherein be provided with a high temperature steel samming tube in the induction heater of second Medium Frequency Induction Heating Furnace, be heated workpiece and place in this high temperature steel samming tube.The effect of first Medium Frequency Induction Heating Furnace is rapidly workpiece to be heated to certain temperature; The induction heater of second Medium Frequency Induction Heating Furnace is heated to certain temperature with high temperature steel samming tube earlier, form the heating atmosphere of a temperature-stable, then workpiece is sent into the high temperature steel samming tube of second Medium Frequency Induction Heating Furnace from first Medium Frequency Induction Heating Furnace, make its samming diathermanous, reach the requirement of the heating of quenching.Here, high temperature steel samming tube is equivalent to a stable thermal source again both as furnace lining, so workpiece both had been subjected to the heating of inductor block in second Medium Frequency Induction Heating Furnace, be subjected to the heating of high temperature steel samming tube again.
In order further to raise the efficiency, above-mentioned tempering heating unit can be made up of the 3rd Medium Frequency Induction Heating Furnace that is used to heat and the 4th resistance heading furnace that is used to be incubated.The 3rd Medium Frequency Induction Heating Furnace is heated to tempering temperature with workpiece earlier, enters the 4th resistance heading furnace then and is incubated.This combined heated mode has been utilized the advantage of induction heating and resistance furnace heating respectively, has shortened the time of whole tempering process greatly.
Compared with prior art, the utility model rate of heating is fast, heating quality is high, and is free from environmental pollution, can not produce the oxidation and decarbonization defective, and is easy to realize mechanize and automatization.The utility model is specially adapted to the thermal treatment of the axletree axis body of heavy-duty car.

Embodiment
Fig. 1, Fig. 2 have provided that an embodiment of the present utility model---be exclusively used in the thermal treatment of heavy-duty car axletree axis body, wherein Fig. 1 has represented the floor plan of each process furnace.The shape of Automobile shaft axis body is as shown in Figure 3, Figure 4: axletree axis body hollow, its middle part is square, two ends are stepped, because outer shape, external diameter, internal diameter and wall thickness change vertically, adopt the inductor block heating of a routine to be difficult to make workpiece to reach desired temperature homogeneity merely.
As shown in Figure 1 and Figure 2: be exclusively used in the heat treated heating unit of axletree axis body and mainly form by first Medium Frequency Induction Heating Furnace 1, second Medium Frequency Induction Heating Furnace 2, the 3rd Medium Frequency Induction Heating Furnace 3 and the 4th resistance heading furnace 4 that is used to be incubated, wherein be provided with a high temperature steel samming tube 21 in the induction heater of second Medium Frequency Induction Heating Furnace 2, be heated workpiece 6 and be positioned at this high temperature steel samming tube 21.The section of high temperature steel samming tube 21 is square, and its wall thickness can be 10～20 millimeters, and the wall thickness of the high temperature steel samming tube of this example is 12 millimeters.During work, earlier workpiece 6 (axletree axis body) is sent into first Medium Frequency Induction Heating Furnace 1 and be heated to certain temperature; By conveying belt 51 workpiece is sent in second Medium Frequency Induction Heating Furnace 2 then, high temperature steel samming tube 21 sensed devices in the process furnace 2 are heated to 900-1000 ℃ at this moment, workpiece is realized samming, insulation in high temperature steel samming tube 21, up to desired quenching temperature.Workpiece 6 carries out water-cooled immediately after second Medium Frequency Induction Heating Furnace 2 is come out---quenches, workpiece after the quenching enters the 3rd Medium Frequency Induction Heating Furnace 3 by conveying belt 52 and is heated rapidly to tempering temperature, and then send into the insulation of the 4th resistance heading furnace 4 by conveying belt 53, carry out temper, whole process is all carried out automatically.After testing, by the insulation of the second Medium Frequency Induction Heating Furnace high temperature steel samming tube, the temperature of workpiece each several part is very even, can satisfy heat treated requirement fully; And the associating type of heating that adopts induction heating and resistance furnace to heat has not only reduced energy consumption, and its production efficiency also improves greatly.
