Problems solved by technology

[0003] The current quenching and cooling device mainly uses tooling to load multiple parts in the quenching equipment for cooling. Due to the limitation of the flow field in the quenching equipment, the flow field is not uniform during cooling, and the flow rate is uncontrollable.
After the parts are quenched, the dispersion of product performance and deformation is very large, which makes the parts prone to failure in mechanics and metallurgy after quenching, and problems such as cracking and out-of-tolerance deformation may also occur.

Abstract

The invention discloses a buried liquid quenching and spraying device. The device comprises an outer groove for accommodating quenching mediums, a lifting platform for bearing parts, and a lifting device for driving the lifting platform to lift. The buried liquid quenching and spraying device suitable for parts with inner holes further comprises an inner spraying device for spraying the inner holes of the parts, an outer spraying device for spraying the outer side surfaces of the parts, a first circulating device for extracting the quenching mediums in the outer groove to spray by the inner spraying device, and a second circulating device for extracting the quenching mediums in the outer groove to spray by the outer spraying device. The buried liquid quenching and spraying device effectively guarantees the internal and external hardness of the parts, and controls the consistency of different batches of parts.

Description

technical field [0001] The invention relates to a cooling device in a quenching process, in particular to a buried liquid quenching spray device. Background technique [0002] Quenching is an important link in the heat treatment process, and almost all components requiring mechanical properties need to be quenched and cooled. [0003] The current quenching and cooling device mainly uses tooling to load multiple parts in the quenching equipment for cooling. Due to the limitation of the flow field in the quenching equipment, the flow field is not uniform during cooling, and the flow rate is uncontrollable. After the parts are quenched, the dispersion of product performance and deformation is very large, which makes the parts prone to failure in mechanics and metallurgy after quenching, and problems such as cracking and out-of-tolerance deformation may also occur. How to make the product quality stable, product performance and deformation better, this needs to ensure the cooli...
