Vector spraying and quenching device suitable for complex-shaped part

Abstract

The invention discloses a vector spraying and quenching device suitable for a complex-shape part. The vector spraying and quenching device comprises a quenching furnace box body, a plurality of transmission rollers and a plurality of vector sprayers; the vector spraying and quenching device is characterized in that each vector sprayer is composed of a base, a rotary stepping motor, a feeding stepping motor, a swinging stepping motor, a water conveying pipe, a top seat and a swinging plate, one end of the swing plate is fixedly provided with a nozzle, and the other end of the swing plate is fixed on an output shaft of the swing stepping motor; the feeding stepping motor drives a vertical shaft to ascend or descend in the vertical direction through a lifting transmission mechanism, the rotary stepping motor drives the vertical shaft to rotate around the vertical direction through a rotary transmission mechanism, and the swing stepping motor is used for driving the nozzle to swing. According to the vector spraying and quenching device, uniform spraying of a polyhedral part can be realized, uniform and rapid cooling of the polyhedral part in the spraying and quenching process is realized, deformation and the residual stress in the spraying and quenching process of the part can be prevented from being too large, and the mechanical property of the part after quenching is ensured.

Description

technical field [0001] The present invention relates to a spray quenching device, more specifically, to a vector spray suitable for parts with complex shapes, which realizes uniform water distribution by making the spraying directions of multiple vector sprayers face different positions of the parts Quenching device. Background technique [0002] In order to improve the mechanical properties of metal parts to meet the design and use requirements, the parts need to undergo heat treatment processes, including solid solution and quenching processes. Among them, the quenching process, as a key link to control the residual stress of parts to obtain ideal mechanical properties, is the most difficult and challenging process in the heat treatment process. The traditional quenching process usually adopts salt bath + pool bath quenching (pool quenching) method for production. However, there are many deficiencies in this quenching process. First of all, the pool quenching method has...

Problems solved by technology

When spray cooling parts with complex shapes, it is necessary to spray cooling in multiple directions at the same time to achieve rapid and uniform cooling. The existing nozzles arranged up and down in the furnace cannot meet the requirements, which seriously hinders the spraying of complex parts. Shower cooling production work
