Description

Technical Field

[0001] The utility model belongs to the technical field of spring processing, and particularly relates to a tempering device for spring processing. Background Art

[0002] The continuous hot air tempering furnace is a continuous industrial heat treatment equipment. As long as the processed metal material is fed into the furnace chamber from the inlet of the furnace by the conveyor mesh belt, the whole heating process is completed when the workpiece continuously moves towards the outlet. The treatment temperature can reach 650 degrees Celsius. Therefore, it is widely applicable to the continuous tempering of batch workpieces such as springs, spring washers, chains, standard parts, vehicle accessories, bearings, piston rings, hardware products, and carburized and quenched parts, and has the advantages of high operation efficiency, labor saving and time saving. The existing tempering furnace generally conveys workpieces through a conveyor belt for heating and tempering. However, during the whole conveying process, hot air blows on the workpiece from directly above, and the heating efficiency of the bottom and top of the workpiece is different, affecting the tempering effect.
