Description

Technical Field

[0001] The utility model belongs to the technical field of metal heat treatment equipment, and in particular relates to a heat treatment device for metal processing with uniform temperature reduction. Background Art

[0002] During the metal processing process, the metal needs to be heat treated. The heat treatment process is a process method in which the metal workpiece is placed in a medium for heating, insulation, and cooling, thereby changing the surface or internal structure of the metal workpiece to control the metal properties. Metal heat treatment is divided into four heat treatment processes: annealing, normalizing, quenching, and tempering, and the four heat treatment industries have different temperature control.

[0003] The quenching process in metal heat treatment requires rapid cooling of the metal workpiece after heat treatment, making the metal hard and brittle. The traditional cooling device for metal heat treatment is difficult to transfer the metal from the heat treatment furnace to the cooling device, and the speed is relatively slow, which seriously affects production efficiency.

[0004] The patent with the publication number CN215887145U discloses a rapid cooling device for metal heat treatment, including a pool body, a top cover on the top of the pool body, and four connecting rods at the bottom of the top cover; a water collecting pool is installed at the bottom of the pool body, the water collecting pool is connected to the pool body through a water flow hole, a mounting block is provided on the inner wall of the water collecting pool, and a filter is installed on the top of the mounting block; a box is installed at the bottom of the water collecting pool, the box body and the water collecting pool are connected through a drainage pipe, a water reservoir is provided inside the box body directly below the drainage pipe, a refrigerator is installed inside the box body next to the water reservoir, the refrigerator and the water reservoir are connected through a first water pipe, a second water pipe is provided at the liquid outlet of the refrigerator, and a water pump is installed at the liquid outlet of the second water pipe. The rapid cooling device for metal heat treatment is simple to operate, can effectively and quickly reduce the heat of metal processed parts after heat treatment, speed up production efficiency, and reduce operating costs.

[0005] However, the device can only spray water at a single angle to cool the metal, and cannot spray water at multiple angles to cool the metal, and the cooling efficiency is average. Utility Model Content
