AI Technical Summary

Technical Problem

Existing bogie-type quenching furnaces have problems such as uneven oil temperature, insufficient internal cooling, and oil vapor film hindering cooling during the quenching process, which leads to uneven quenching quality and the risk of workpiece deformation and cracking.

Method used

A circulating chain conveyor, combined with a passive transmission mechanism and a clamping mechanism, is used to realize the rotation and lifting motion of the workpiece in the quenching liquid, ensuring that each position is in uniform contact with the quenching liquid, and the surface film is blown off by a fan to improve the cooling uniformity.

Benefits of technology

It achieves uniformity and efficiency in quenching quality, reduces the risk of workpiece deformation and cracking, and improves production efficiency and automation.

Abstract

The application discloses a quenching tank and quenching process for high-toughness wear-resistant alloy steel, and is based on chain conveying, and utilizes power in the walking process to automatically drive the workpiece to rotate in the quenching liquid, and in this way of being immersed and rotated, the film on the surface of the workpiece is effectively broken, and each hole and the corner of the special-shaped structure is fully contacted with the quenching liquid, so that uniform cooling is ensured, and the risk of deformation and cracking of the workpiece caused by uneven cooling is significantly reduced, and high automation and efficient production are realized while the quenching quality is improved.
