Glass kiln transition roller machining method

Abstract

The invention provides a glass kiln transition roller machining method. The glass kiln transition roller machining method comprises the steps that firstly, a roller body of a transition roller is machined, the periphery of the roller body subjected to centrifugal casting forming is turned, and meanwhile, an inner hole of the roller body is bored and washed; secondly, a shaft head of the transitionroller is machined, stainless steel round steel is adopted for forging treatment, and then the periphery of the stainless steel round steel is turned; thirdly, a supporting piece of the transition roller is machined, the periphery of the supporting piece subjected to centrifugal casting forming is turned, and meanwhile, the inner hole of the roller body is bored and washed; fourthly, the shaft head, the supporting piece and the roller body are assembled into the transition roller; and fifthly, the transition roller is subjected to finish machining. The machining efficiency of the transition roller is improved, and the finished production rate of the transition roller is increased.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a glass kiln transition roll. Background technique [0002] At present, the glass industry is developing rapidly, the production capacity is increasing, and new technologies around the float production line are emerging. In furnaces, tin baths, annealing kilns and cold-end equipment, transition rollers are used to connect tin baths and annealing kilns. A very important key equipment from free state to elastic freezing state, directly affects the internal stress structure and external surface quality of the glass, and is the first hard material that float glass contacts after forming. The working temperature of the transition roller is between 300 and 400 degrees, and it needs to be heat-resistant, wear-resistant and deformation-resistant. Therefore, the manufacturing acceptance of the transition roller has high quality requirements, the surf...

AI Technical Summary

Problems solved by technology

Based on the above requirements, in the process of processing the transition roller in the prior art, the roller body is made by centrifugal casting and the outer periphery is turned. However, because the casting stress is difficult to eliminate, the quality is unstable, and it is easy to cause deformation. Difficult to guarantee; at the same time, the shaft head is generally made of steel pipe, which does not bear enough gravity and is prone to breakage during use
