AI Technical Summary

Technical Problem

In existing tool quenching devices, the efficiency of the cooling medium is low, the temperature of the cooling medium rises, affecting the cooling effect, and the tool is easily immersed and left to stand during the cooling process, resulting in low efficiency.

Method used

A cooling device comprising a first quenching box assembly, a second quenching box assembly, and a third quenching box assembly was designed. The device enables the tool to move and cool in the cooling medium through a transmission assembly and a quenching partition assembly. The medium temperature is controlled by a fan and a guide pipe to adapt to different quenching requirements.

Benefits of technology

It improves the efficiency of tool quenching, ensures stable cooling medium temperature, and prevents the tool from being directly immersed in the cooling process, thereby enhancing the cooling speed and efficiency and adapting to different processing needs.

Abstract

The application relates to the technical field of quenching devices, and more particularly discloses a cooling device for knives after heat treatment, which comprises a first quenching box assembly, one side of the top of the first quenching box assembly is fixedly connected with a second quenching box assembly, the front of the first quenching box assembly is provided with a first fan, the other side of the top of the first quenching box assembly is provided with a third quenching box assembly, the inner sides of the first quenching box assembly, the second quenching box assembly and the third quenching box assembly are provided with a transmission assembly, the outer side of the transmission assembly is provided with a quenching partition plate assembly, the back of the first quenching box assembly is provided with a second fan, and the center of the top of the first quenching box assembly is fixedly connected with a sealing cover plate. The cooling medium in contact with the knives is changed all the time during the movement of the knives, so that the cooling speed of the knives is accelerated; the knives automatically separate from the cooling medium after quenching, and the cooling medium can be separated, so that the quenching efficiency of the knives is ensured.
