Quenching medium stirring cooling device

Abstract

The invention discloses a quenching medium stirring cooling device. Propeller stirrers are arranged on the outer edge of a quenching liquid tank, the propeller stirrers are in 120 degree angle with each other and are driven by propeller speed regulation motors, and a cooling water circulation system is arranged between the periphery of the outer edge of the quenching liquid tank and a concrete waterproof wall. The propeller stirring direction and the quenching liquid tank center form a 5 degree angle, and the rotation direction of a quenching workpiece is opposite to that of a quenching medium. The quenching medium stirring cooling device can fully quench the workpiece to ensure the quenching quality by quenching liquid stirring, cooling water cooling and workpiece rotation manners, and is suitable for using as a workpiece quenching device.

Description

technical field

[0001] The invention proposes a quenching facility in the mechanical field, specifically a quenching medium stirring and cooling device. Background technique

[0002] The quenching and cooling mechanism is to control the composition, temperature, flow rate, pressure and medium stirring and cooling of the quenching medium to meet the requirements of the quenching and cooling capacity of the quenching parts, and to achieve the purpose of obtaining the expected structure and performance of the quenching parts. For the above parameters, medium agitation and cooling is one of the most important factors in quenching. The effect of medium agitation and cooling is to increase the intensity of quenching. The ability of quenching medium to absorb heat from steel parts is usually determined by the type of medium, temperature, stirring and other factors.

[0003] Improve the uniformity of the temperature of the quenching medium, stirring can make the medium in the entir...

Examples

Embodiment Construction

[0018] As shown in the figure, a propeller agitator 4 driven by a propeller speed regulating motor 5 is installed on the outer edge of the quenching liquid tank 3 at an angle of 120 degrees, and a cooling water circulation is provided between the periphery of the quenching liquid tank and the concrete waterproof wall 1 System 2.

[0019] Working process of the present invention: the quenching medium stirring and cooling device refers to the mode of combining propeller stirring mode, circulation pump cooling and manual rotation.

[0020] There is an included angle of 5° between the stirring direction of the propeller and the center of the quenching liquid tank. The propeller pushes the quenching medium to generate an eccentric oblique force when it is working, and the three propellers push the quenching medium to move in a circle. The other part of the force is under the action of the three propellers, and the liquid flow collides with each other to generate upward and downward...
