Quenching furnace for tubular parts

Abstract

The invention discloses a quenching furnace for tubular parts. The quenching furnace comprises a furnace body, wherein a cavity is formed in the furnace body, the two opposite side walls of the furnace body are provided with an inlet and an outlet which are used for allowing the part to be treated to penetrate through, a clamping unit, a cleaning unit, a first drying unit, a heating unit, a cooling unit and a second drying unit are sequentially arranged in the furnace body according to procedures, the furnace body inlet corresponds to the clamping unit, and the second drying unit corresponds to the furnace body outlet; a power unit comprises a motor, and the motor provides power for the clamping unit, the cleaning unit, the first drying unit, the cooling unit and the second drying unit atthe same time; the heating unit is electrically connected with a power supply; and the clamping unit can reciprocate in the moving direction of the part to be treated and complete the clamping and loosening functions of the part to be treated. According to the quenching furnace, a part is clamped by the clamping unit to move forwards, the part is subjected to cleaning, primary drying, heating, cooling and secondary drying, the tubular part is quenched and dried, and high practicability is achieved.

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 do
