Description

Technical Field

[0001] The utility model relates to the field of glass manufacturing, in particular to a shaft head welding device for a glass conveying roller. Background Art

[0002] With the rapid development of the glass manufacturing industry, the glass conveyor roller head is a key component, and the optimization and improvement of its manufacturing process method is of great significance to improving glass production efficiency, reducing production costs and improving product quality.

[0003] The shaft head of the glass conveyor roller is used for the glass conveyor roller. A large number of them are used on each production line, with a certain batch size. After the shaft head is welded, it needs to be transferred to the subsequent process. The production cycle is long. Therefore, the welding of the shaft head is a part that is urgently needed to improve the manufacturing efficiency in the glass production process.

[0004] The shaft head of a glass conveyor roller is thin at the top and thick at the bottom, similar to a pagoda-shaped structure. When manufacturing its blank, a steel shaft ring is often welded to a round steel shaft body to save materials. The existing welding method of the shaft ring and the shaft body is the traditional manual mode, that is, the worker holds a welding gun to weld. Because the weld between the shaft ring and the shaft body is circular, the worker often needs to rotate the workpiece during welding while controlling the welding gun with his wrist to perform welding. This welding method is time-consuming and labor-intensive. Only about 80 pieces can be welded in one shift. The production efficiency is low and the welding quality is unstable, which affects the overall performance and service life of the shaft head. In addition, manual welding is intensive and the welding environment is complex, which is very harmful to the welder. The welding dust and gas generated cannot be uniformly handled, and the welding arc also poses a threat to the surrounding working environment. Utility Model Content
