Description

Technical Field

[0001] The utility model relates to the technical field of intermediate frequency induction furnaces, and particularly relates to an intermediate frequency induction furnace with a rapid cooling function. Background Art

[0002] The intermediate frequency induction furnace rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into adjustable intermediate frequency current to supply a load circuit composed of a capacitor and an induction coil. When an alternating current passes through the induction coil, an alternating magnetic field will be generated around it. When a metal workpiece is placed in this magnetic field, eddy currents will be induced inside the workpiece by the alternating magnetic field. Due to the resistance of the metal workpiece, these eddy currents will generate heat, thereby heating up the workpiece.

[0003] Therefore, the patent specification with the publication number of CN210346289U discloses an anti-oxidation intermediate frequency induction furnace, which includes a furnace body shell, a furnace lining and a heating coil. The heating coil is arranged around the outer wall of the furnace lining. The furnace lining includes a melting furnace cavity and a heat preservation furnace cavity. The melting furnace cavity is located inside the heat preservation furnace cavity, and a penetration port communicating with the heat preservation furnace cavity is provided at the bottom of the melting furnace cavity. The top of the heat preservation furnace cavity is in a closed state, and a furnace nozzle is integrally provided on the heat preservation furnace cavity. A sealing cover is movably covered on the cavity cover. This intermediate frequency induction furnace adopts a furnace lining structure with an inner melting furnace cavity and an outer heat preservation furnace cavity, so that the molten metal liquid and the solid metal are separated, and the metal liquid enters the heat preservation furnace cavity, reducing the contact surface of the metal liquid with the ambient air and inhibiting the oxidation of the metal liquid. Combined with introducing inert gas into the melting furnace cavity, the solid metal is prevented from being oxidized during the melting process. The same heating coil acts on the two furnace cavities at the same time, so that the two furnace cavities provide heat and insulation for each other, and the heat energy generated by the two furnace cavities is fully utilized.

[0004] During the use of the above-mentioned technology, the same heating coil acts on the two furnace cavities at the same time, so that the two furnace cavities provide heat and insulation for each other, and the heat energy generated by the two furnace cavities is fully utilized. However, after the heating is completed, it is inconvenient to pour out the metal liquid inside the crucible, making it troublesome to pour the metal liquid. Therefore, an intermediate frequency induction furnace with a rapid cooling function is needed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an intermediate frequency induction furnace with a rapid cooling function to solve the defect that it is inconvenient to pour out the metal inside the crucible easily after the existing intermediate frequency induction furnace finishes heating the metal.

The installation box is fixed on one side of the first bracket, and a turbine is installed inside the installation box.

[0007] Preferably, one end of the turbine is provided with a connecting shaft, one end of the connecting shaft is fixed to one side of the induction furnace main body, the fixed shaft is arranged at the other end of the induction furnace main body, a worm is installed at the top end of the turbine, and a motor is installed on one side of the installation box.

[0008] Preferably, the output end of the motor extends into the installation box, and the output end of the motor is fixed to one end of the worm.

[0009] Preferably, a plurality of teeth are arranged on the outer side of the turbine, and the worm is meshed with the turbine.

[0010] Preferably, one end of the fixed shaft penetrates through the inside of the second bracket, and one end of the fixed shaft is movably connected inside the second bracket.

[0011] Preferably, the cooling structure includes a water inlet, a water outlet, and a circulation pipe. The circulation pipe is installed at the bottom end inside the induction furnace main body. One end of the circulation pipe is provided with a water inlet, and the other end of the circulation pipe is provided with a water outlet.

[0012] Preferably, a plurality of yokes are provided, and the plurality of yokes are annularly distributed outside the coil.

[0013] The advantages of a fast-cooling intermediate frequency induction furnace provided by the present utility model are as follows:

[0014] Through the combined use of the motor, the worm, and the turbine, when the molten metal inside the crucible is heated and needs to be poured, the induction furnace main body can be driven to tilt to one side, making it more convenient to pour the molten metal, thereby improving the convenience;

[0015] Through the setting of the temperature sensor, the temperature inside the induction furnace main body can be monitored. When the temperature inside the induction furnace main body is higher than the workpiece heating temperature, the water inlet is externally connected to cold water, so that the cold water flows into the circulation pipe, and then flows out through the circulation pipe. The temperature inside the induction furnace main body is quickly reduced through heat exchange to a temperature suitable for workpiece heating, thereby improving the cooling effect.
