Description

Welding predeformation frock

Technical Field

The embodiment of the disclosure relates to the technical field of welding tools, in particular to a welding pre-deformation tool.

Background

Many workpieces can generate certain deformation in the welding process, which causes the problems of surface flatness deterioration, etc., and implementing pre-deformation on the workpieces is one of the methods for solving the problems, and a welding pre-deformation tool is used. Welding pre-deformation tooling is required in the welding process of a plurality of products in many fields, for example, the pre-deformation tooling is required in the welding process of a glass substrate packing box. The glass substrate is a thin glass sheet with an extremely flat surface, the thickness of the glass is 0.4mm, 0.5mm, 0.7mm and the like, and the glass substrate is a basic component for forming a liquid crystal display and is one of key basic materials of the flat panel display industry. The glass substrate packing box is an indispensable tool specially used for packing and transporting glass substrates, and because the glass substrates are large and thin, the requirements on the manufacturing precision of the packing box in the processing and transporting processes are very strict, such as the flatness of a back plate frame of the packing box and the consistency of the packing box. If the manufacturing requirements are not met, batch glass substrates are easy to damage in the transportation process, or the manipulator cannot normally grab the glass from the packing box in the production process.

The manufacturing precision requirements of the glass substrate packing box are all completed through a welding process. The prior art welding techniques are typically: the back plate frame of the glass substrate packing box is welded on the platform, then the supporting ribs are welded, after the supporting ribs are welded, the back plate frame can generate bow-shaped deformation towards the direction of the supporting ribs, and at the moment, the welded and deformed back plate frame needs to be leveled on a hydraulic leveling machine, so that the requirement of the back plate frame on the flatness is met. The process needs a special orthopedic procedure, the production turnaround period is long, and the flatness consistency of the product is poor.

Accordingly, there is a need to ameliorate one or more of the problems with the related art solutions described above.

It is noted that this section is intended to provide a background or context to the embodiments of the disclosure that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
