Electromagnetic induction heating motor, heading system, and heating method

Abstract

The invention relates to an electromagnetic induction heating motor comprising a motor body and an electromagnetic induction heating device. The electromagnetic induction heating device comprises a driving turntable sleeving a motor shaft of a motor body, a driving turntable compressing plate being arranged at the outer end surface and being fixedly connected to the motor shaft, and an electromagnetic induction disc being fixedly connected to the outer end surface of the driving turntable. A plurality of rectangular grooves are distributed on the electromagnetic induction disc uniformly alongthe circumferential direction and center lines of the rectangular grooves point to the circular center of the electromagnetic induction disk to form adial arrangement; and N-Pole or S-pole magnetic steel plates orienting to the bottoms of the grooves together are arranged in the grooves. According to the novel provided unique mode of heating a metal blank material, the metal blank material is heated by using electromagnetic induction and the electromagnetic induction disc being a core element for heating has no temperature rising during the heating process, so that no thermal losses are causedand energy-saving and environment-friendly effects are good. The electromagnetic induction heating motor has advantages of reasonable structure, wide application range, low manufacturing cost and good local heating capability and the like.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an electromagnetic induction heating motor, a heating system and a heating method. Background technique [0002] In the thermoforming process of metal, the metal blank needs to be heated first before forming. For example, in the thermoforming of aluminum profiles, the aluminum rod must first be heated to the required forming process temperature, and then extruded into a material through forging or forming dies. [0003] Generally, furnace heating or combustion device heating is used for heating metal blanks, and electric heating wires, heating tubes, etc. are also used for heating. Among them, furnace heating and combustion device heating need to be equipped with a complete set of furnace equipment or combustion device. Put the billet to be heated as a whole into the heating furnace or combustion device, which is suitable for heating a large number of billets of the same type, an...

Problems solved by technology

Among them, furnace heating and combustion device heating need to be equipped with a complete set of furnace equipment or combustion device. Put the billet to be heated as a whole into the heating furnace or combustion device, which is suitable for heating a large number of billets of the same type, and the equipment cost is high, so it is not applicable. It is suitable for the heating of billets of different types in small batches of single pieces, and local heating of the billets cannot be carried out. Heating by means of combustion will also generate smoke, which is not conducive to environmental protection; heating methods such as electric heating wires and heating pipes mostly adopt contact heat conduction Although the heating method can realize the heating of different types of blanks in small batches, the resistance heating element is used, which has low power efficiency and high power consumption. Uniform, large heat loss during heating

In addition to the above heating methods, other more advantageous and potential methods have not been reported
