Description

Technical Field

[0001] The utility model relates to the technical field of gear quenching, in particular to a gear high-frequency quenching device. Background Art

[0002] A gear is a mechanical element with teeth on its rim that can continuously mesh to transmit motion and power. During the gear manufacturing process, through quenching treatment, the surface hardness and wear resistance of the gear can be significantly improved. At the same time, the internal structure is more uniform and dense, which improves the gear's load-bearing capacity and fatigue resistance.

[0003] The existing gear quenching device is mainly composed of an electromagnetic heating coil, an electromagnetic heating controller, a quenching machine and a cold zone tank. Its working principle is mainly based on the principles of electromagnetic induction and heat treatment. When quenching, the gear is placed in the electromagnetic heating coil. Through the action of the electromagnetic heating coil, an alternating magnetic field is generated around it. The electromagnetic induction effect of the alternating magnetic field causes a closed induced current to be generated inside the gear. The electrical energy of the high-density current on the surface of the gear is converted into thermal energy, which increases the temperature of the surface, thereby achieving surface heating. After the gear surface is heated, the heated gear is placed in a cooling tank to cool the gear, thereby achieving surface quenching.

[0004] The existing quenching device requires frequent loading and unloading operations during quenching, which takes too long and greatly increases the labor intensity of the operators. It cannot meet the requirements of efficient and continuous quenching operations, greatly reducing the overall efficiency of the production line. Therefore, a gear high-frequency quenching device is proposed to address the above problems. Utility Model Content

Through the operation of automatic loading and unloading cooling, there is no need to frequently load and unload, so that the quenching operation can be efficiently and continuously realized, which greatly improves the quenching efficiency and further improves the overall efficiency of the production line.

[0009] Preferably, a cooling groove is provided on the base, and the cooling groove is provided obliquely below the quenching box. When the device is used, the heated gear can be cooled by providing the cooling groove.
