Chain track quenching device controlling quenching strength based on ventilation quantity

Abstract

The invention discloses a chain track quenching device controlling quenching strength based on a ventilation quantity. A cooling cylinder is included, and the left and right sides of the cooling cylinder are each connected with a supporting plate; driving motors are installed on the supporting plates, and the front ends of the driving motors sequentially penetrate through extruding frames and thecooling cylinder through worms; rotors are connected to the portions, located in the extruding frames, of the worms; gas conveying hoses penetrate through the positions between the rotors and the extruding frames, and the two ends of each gas conveying hose both penetrate through the corresponding extruding frame; the gas conveying hoses are connected to gas conveying branch pipes which are arranged on a first gas conveying main pipe; a one-way valve is installed on the first gas conveying main pipe on which a flow meter is arranged; the lower end of the first gas conveying main pipe penetrates through the cooling cylinder and is connected with a second gas conveying main pipe; and a sealed plate is connected to the second gas conveying main pipe. The chain track quenching device controlling quenching strength based on the ventilation quantity can control the strength of quenching by controlling the ventilation quantity, and therefore the strength of a chain track after being quenchedcan be conveniently controlled.

Description

technical field [0001] The invention relates to the related technical field of chain rail quenching, in particular to a chain rail quenching device for controlling quenching intensity based on ventilation volume. Background technique [0002] During the production process of the chain rail, it is bound to undergo a quenching process. This is because quenching can increase the strength of the chain rail, thereby ensuring the stable use of the chain rail. The quenching process is divided into three parts: heating, heat preservation and cooling. In the cooling stage of quenching, the cooling speed is closely related to the strength of quenching. If you want to control the strength of the chain rail, you must control the cooling speed in the cooling stage of quenching. [0003] However, the quenching device of the existing chain rail cannot control the cooling speed by controlling the ventilation rate. Because the existing quenching device generally directly places the chain rai...
