Welding equipment

Abstract

The invention discloses welding equipment. According to the welding equipment, the problem that a welding gap between two round tubes cannot be adjusted during existing round tube welding is solved through a clamping device. A plurality of round tubes to be welded are clamped through a first clamping assembly and a second clamping assembly, the second clamping assembly is driven by a lifting assembly to move upwards, and the second clamping assembly is driven by an overturning assembly to overturn by 180 degrees. Multiple round tubes are clamped at the same time through the first clamping assembly, the problem that an existing welding machine cannot clamp the multiple round tubes at the same time is solved, a clamping oil cylinder is used for driving a driving clamping block to move in the direction close to an initial clamping block, springs A, a spring B and a spring C are compressed, transition clamping blocks are driven to move in the direction close to the initial clamping block, and the multiple round tubes are clamped at the same time; the lifting assembly drives the second clamping assembly to move up and down, so that the welding gap is adjusted; and a pair of welding devices each complete 180-degree welding of an annular welding joint, and weld the front half part and the rear half part of the annular welding joint correspondingly.

Description

technical field [0001] In particular, the invention relates to a welding device. Background technique [0002] Round pipes are open at both ends and have a hollow concentric section, which can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes. The manufacturing process of round pipes includes cutting, cutting to length, welding, grinding and so on. [0003] Welding is one of the important steps in the processing of round pipes, which is completed on the welding machine, but the existing round pipe welding machines have the following problems: one is that the welding gap between the two round pipes cannot be adjusted as required when the round pipes are welded, and the welding effect cannot be adjusted. Not good, it affects the service life of the pipeline; the second is that multiple round pipes cannot be clamped at the same time, and the clamping and loosening actions must be repea...

[0003] Welding is one of the important steps in the processing of round pipes, which is completed on the welding machine, but the existing round pipe welding machines have the following problems: one is that the welding gap between the two round pipes cannot be adjusted as required when the round pipes are welded, and the welding effect cannot be adjusted. Not good, it affects the service life of the pipe; second, it is impossible to clamp multiple round pipes at the same time, and the clamping and loosening actions must be repeated each time, and the welding efficiency is low
