A quenching furnace for tubular parts

Abstract

The invention relates to a quenching furnace for tubular parts, which comprises a furnace body provided with a cavity, two opposite side walls of the furnace body are provided with an inlet and an outlet for passing through the parts to be processed, and the furnace body is sequentially provided with clamps according to the process. unit, cleaning unit, first drying unit, heating unit, cooling unit, second drying unit, the inlet of the furnace body corresponds to the clamping unit, and the second drying unit corresponds to the outlet of the furnace body; the power unit includes a motor, and the motor is also a clamp The holding unit, cleaning unit, first drying unit, cooling unit, and second drying unit provide power; the heating unit is electrically connected to the power supply; the clamping unit can reciprocate along the moving direction of the parts to be processed, and complete the clamping, Release function. The invention clamps the parts forward by the clamping unit, and quenches and dries the tubular parts through cleaning, primary drying, heating, cooling and secondary drying of the parts, and has strong practicability.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, in particular to a quenching furnace for tubular parts. Background technique [0002] Quenching is a heat treatment process that heats steel above the critical temperature, holds it for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite, bainite or austenite. Induction hardening is a quenching method that uses electromagnetic induction to generate eddy currents in the workpiece to heat the workpiece, and then rapidly cools the heated workpiece. [0003] The disadvantages of existing quenching furnaces for tubular parts are: 1. The existing quenching furnace drives the parts forward, cooling and drying through multiple power sources, which increases the cost and is not convenient to ensure the synchronization of the processing technology; 2. The existing quenching furnace drives the parts fo...

Problems solved by technology

[0003] The disadvantages of existing quenching furnaces for tubular parts are: 1. The existing quenching furnace drives the parts forward, cooling and drying through multiple power sources, which increases the cost and is not convenient to ensure the synchronization of the processing technology; 2. The existing quenching furnace drives the parts forward by setting multiple and independent power, which increases the space occupation and cost of the equipment, and is not convenient for the maintenance of the later parts; 3. The existing quenching furnace does not include the same power to drive the heat treatment In the previous parts cleaning and parts drying, impurities on the surface of the parts to be processed during heat treatment will affect the quality of heat treatment; 4. When the existing quenching furnace cools the heated parts, the hot gas generated is directly discharged into the air, wasting 5. The existing quenching furnace controls the clamping components to move forward through the sensor, and the reliability of the sensor is lower than that of the mechanical transmission clamping forward.
