Quenching equipment for completing quenching, isothermal treatment or tempering in same slot by transferring through hanging basket

Abstract

The invention relates to thermal treatment equipment and specifically relates to quenching equipment for completing quenching, isothermal treatment or tempering in the same slot by transferring through a hanging basket. The quenching equipment comprises a heating furnace, a discharging table, a quenching slot, an isothermal slot, an air-cooling slot, a saline water cleaning slot, a clear water cleaning slot and an unloading table, wherein the quenching slot, the isothermal slot, the air-cooling slot, the saline water cleaning slot and the clear water cleaning slot are arranged between the discharging table and the unloading table in sequence; the quenching slot and the isothermal slot are formed by dividing a liquid-connected large slot through an adjustable baffle plate; a transfer mechanical hand is arranged above the discharging table and the unloading table; a material taking hook of the transfer mechanical hand is equipped with the hanging basket for hanging and transferring workpieces. The quenching equipment disclosed by the invention can sufficiently utilize heat energy and lower thermal treatment process cost; by adopting a mode that liquid transfers heat for workpieces, tempering and isothermal temperatures of workpieces are more uniform, and better thermal treatment effect is obtained; the mechanical hand can realize automatic transfer of workpieces in different working media, and can realize various quenching processes.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a quenching equipment which is transferred in the same tank by a hanging basket to complete quenching, isothermal or tempering. Background technique [0002] At present, the heat treatment equipment for workpieces such as bearing rings and ring gears are mostly heated by rollers or mesh belt furnaces, and then quenched in the quenching tank with rollers or mesh belts, and then enter the rollers or mesh belts for air cooling and cleaning equipment , into the roller or mesh belt furnace for isothermal or tempering, the existing problems are: ① Due to the heat transferred from the quenching of the workpiece to the quenching salt tank, the temperature of the salt bath in the quenching salt tank increases, and it is necessary to configure a fan or other methods to control the temperature of the quenching salt tank. The salt liquid is cooled, and the heat is discharged into the atmosphere, a...

[0002] At present, the heat treatment equipment for workpieces such as bearing rings and ring gears are mostly heated by rollers or mesh belt furnaces, and then quenched in the quenching tank with rollers or mesh belts, and then enter the rollers or mesh belts for air cooling and cleaning equipment , into the roller or mesh belt furnace for isothermal or tempering, the existing problems are: ① Due to the heat transferred from the quenching of the workpiece to the quenching salt tank, the temperature of the salt bath in the quenching salt tank increases, and it is necessary to configure a fan or other methods to control the temperature of the quenching salt tank. The salt liquid is cooled, and the heat is discharged into the atmosphere, and the isothermal furnace (salt tank) or tempering furnace used in the subsequent isothermal or tempering process needs to be equipped with a separate heating system to heat the workpiece to the isothermal or tempering temperature required by the process And keep it for a certain period of time, the quenching tank needs to be cooled, and the isothermal furnace (salt tank) or tempering furnace needs to be heated separately, which is a serious waste of energy

②Because the workpiece needs to enter a variety of working media, the equipment needs multiple sets of transmission mechanisms, the equipment structure is complex, and the investment cost and operation cost are high

③The transmission mechanism is in contact with the working medium, causing serious corrosion and deformation, and high failure rate
