Continuous hot air tempering furnace

Abstract

The invention relates to the technical field of heat treatment on metal materials and in particular relates to a continuous hot air tempering furnace. The continuous hot air tempering furnace comprises a tempering furnace body and a transmission mechanism, wherein the transmission mechanism comprises a feeding unit, a conveying unit and a discharging unit; the feeding unit comprises a feeding rack, a feeding power device, a feeding driving roller, a feeding driven roller and a feeding belt; the discharging unit comprises a discharging rack, a discharging power device, a discharging driving roller, a discharging driven roller and a discharging belt; the conveying unit comprises a conveying power device, a roller set, a screen belt and a tensioning device; the roller set comprises an incoming end roller, an outgoing end roller, an adjusting roller and two circulation rollers; the tensioning device is in transmission connection with the adjusting roller; the tensioning degree of the screen belt is controlled by adjusting the relative position of the adjusting roller; a feeding slope platform is fixed on the feeding rack; a discharging slope platform is fixed on the discharging rack. The continuous hot air tempering furnace is low in heat loss, is incapable of causing scald to operators and is capable of effectively ensuring the tensioning degree of the screen belt.

Description

Technical field [0001] The invention relates to the technical field of heat treatment of metal materials, in particular to a continuous hot air tempering furnace. Background technique [0002] The continuous hot air tempering furnace is a continuous operation industrial heat treatment equipment. As long as the processed metal material is fed into the furnace from the entrance of the furnace by the conveyor belt, the whole heating process is completed when the workpiece continues to the exit. , The processing temperature can reach 650℃, so it is widely used for 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, with operational efficiency High, labor-saving and time-saving. Continuous hot air tempering furnace usually includes a tempering furnace body and a transmission mechanism. The mesh belt of the transmission mechanism needs to be ...

AI Technical Summary

Problems solved by technology

The continuous hot air tempering furnace usually includes a tempering furnace body and a transmission mechanism. The mesh belt of the transmission mechanism needs to be driven by the rollers at both ends to realize the transmission function. The roller shaft is installed on the bearing, and the bearing is fixed on the bearing seat; this continuous Although the transmission mechanism of the type hot air tempering furnace can effectively prevent the continuous thermal expansion and contraction during the cycle operation of the mesh belt, thereby avoiding the deformation and damage of the mesh belt, however, a large amount of heat is taken out of the tempering furnace body, and the heat loss is high, not only It is easy to burn the operator, and it is difficult to ensure the tension of the mesh belt
