Bending machine for a plate welding seam

Abstract

A bending machine for a plate welding seam comprises a rack, two sets of pressing rollers, a first driving part, two bending parts and two second driving parts, the two sets of pressing rollers are restrained on the rack in a rotatable mode, the two sets of pressing rollers are arranged side by side in the first direction at intervals, each set of pressing rollers comprises the first pressing roller and the second pressing roller, and the first pressing rollers and the second pressing rollers are arranged side by side along a second direction perpendicular to the first direction; the first driving part is arranged on the rack and used for driving the first pressing rollers to move in the second direction; the two bending parts are restrained on the rack and located between the two sets of pressing rollers, the two bending parts are arranged in the second direction, the two bending parts are each provided with a bending head used for corresponding to a plate welding seam, and the bending heads of the two bending parts are oppositely arranged; and the two second driving parts act on the two bending parts correspondingly and are used for driving the two bending parts to move in the second direction. Compared with the prior art, repeated bending of the welding seam can be achieved, and then detection of the quality of the welding seam is achieved.

Description

technical field [0001] The invention belongs to the technical field of weld seam detection, and in particular relates to a bending machine for plate weld seam. Background technique [0002] In the production process of plates, such as plate and strip steel, the plate and strip steel need to be connected end to end to ensure the continuity of the plate, so the welding of the plate and strip steel is a necessary operation. Due to poor weld quality, weld fracture is one of the important reasons for interrupting normal production. Therefore, the detection of weld quality is very important. [0003] At present, the inspection methods of weld quality are generally divided into manual bending inspection and machine bending inspection. Manual bending inspection of welds has the defect of low operation efficiency, and for thick plates of 3.0mm and above, manual bending is more difficult. [0004] Machine bending detection is mostly realized by bending machines, such as the structure...

AI Technical Summary

Problems solved by technology

[0006] Machine bending detection can overcome the shortcomings of manual bending detection, but the existing bending machines can only bend the weld seam along one side of the plate, and cannot realize the repeated bending action of the weld seam. In line with the reverse force generated by the welding seam around the roll during the process of passing the plate on the production line
