AI Technical Summary

Technical Problem

Traditional hollow tempering furnaces are prone to glass displacement and falling during glass conveying, and the entire roller needs to be replaced after the anti-slip surface of the roller wears out, which is costly.

Method used

A hollow tempering furnace was designed. A clamping plate was welded to the side of the furnace body and a side plate was installed. An internal threaded seat was welded to the side plate and a screw rod was fitted on it. A bearing and a stop bar were installed on the screw rod. A limiting rod passed through the side plate to provide a limiting effect. An anti-slip sleeve was fitted on the roller. A fixing piece was glued inside the anti-slip sleeve and a replaceable insert rod was installed. The slider moved in the slide rail to replace the anti-slip sleeve.

Benefits of technology

It achieves stable limiting of the glass to prevent it from falling, and the anti-slip sleeve can be replaced after wear, reducing replacement costs.

Abstract

This utility model discloses a tempering furnace for hollow tempering processing, including a tempering furnace body, rollers mounted on the surface of the tempering furnace body, a clamping plate welded to the side of the tempering furnace body, a side plate installed inside the clamping plate, an internal threaded seat welded to the surface of the side plate, a lead screw sleeved inside the internal threaded seat, a bearing sleeved on the surface of the lead screw, a stop bar mounted on the surface of the bearing, and a fixing seat welded to the back of the stop bar. This hollow tempering furnace, by welding a clamping plate to the side of the tempering furnace body and installing a side plate inside the clamping plate, and simultaneously welding an internal threaded seat to the surface of the side plate and sleeved a lead screw inside the internal threaded seat, drives the stop bar to move. At this time, the limiting rod and bearing provide a limiting effect for the stop bar, preventing it from rotating with the lead screw. Thus, the stop bar can be used to limit the glass transported on the tempering furnace, preventing the glass from easily falling out and providing a protective effect during use.
