A dual-purpose seat for steel structure welding and correction

Abstract

The invention relates to a dual-purpose seat for welding and correcting a steel structure. The dual-purpose seat comprises a plurality of rows of base beams arranged in parallel, at least three rows of base beams are arranged in parallel, the base beams arranged in parallel can adapt to the length of an H-shaped steel structure or a U-shaped steel structure and can adapt to H-shaped steel structures or U-shaped steel structures of different specifications, the actual welding and correcting needs are met, containing grooves are symmetrically formed in the two sides of each base beam respectively, the left ends and the right ends of the base beams are symmetrically connected with outer corner frames, the middle portions of the base beams are symmetrically connected with inner corner frames, lower locating extruding and pushing devices are arranged in the containing grooves respectively, the lower locating extruding and pushing devices are fixedly connected with the outer corner frames and the base beams, and upper sliding correcting devices are arranged on the inner corner frames respectively. The dual-purpose seat has the advantages of being reasonable in structural design, high in automation degree, high in stability and the like, can be used for steel structure submerged-arc welding, and facilitates welding gun welding, the steel structure can be corrected automatically after welding, correcting efficiency is greatly improved, the steel structure is prevented from being transferred, and the production period of the steel structure is shortened.

Description

technical field [0001] The invention relates to the technical field of steel structure production and processing, in particular to a steel structure welding and correction dual-purpose seat. Background technique [0002] As we all know, steel structures play an important role in buildings, and different structural designs of steel structures will make the building's shape and performance more unique. During production and processing, the steel structure must go through raw material cutting, assembly, submerged arc welding, calibration, shearing drilling, manual welding and forming, shot blasting and painting before it can finally become a steel structure product. Before submerged arc welding, it is necessary to conduct preliminary spot welding on the plates of the steel structure, so that the preliminary positioning and connection between the plates can be carried out. The main purpose is to prepare for submerged arc welding and facilitate welding by welding machines. The t...

Problems solved by technology

The traditional I-shaped steel structure or U-shaped steel structure is directly placed on the welding frame, and then welded along the length direction of the I-shaped steel structure or U-shaped steel structure by a welding machine. After the welding is completed, due to the existence of certain welding Deformation needs to be corrected in a timely manner. The existing factories use the calibration machine for calibration, that is, the welded I-shaped steel structure or U-shaped steel structure needs to be transported to the calibration machine for calibration, while the I-shaped steel structure or U-shaped steel structure The steel structure itself is bulky, cumbersome, and difficult to transfer, resulting in a longer processing cycle for the I-shaped steel structure or U-shaped steel structure, and the production efficiency has not been further improved.

[0003] For example, the Chinese patent application No. 201310350804.X proposes an H-shaped steel assembly welding and straightening machine with a welding deformation correction device, including an assembly and assembly device, a welding forming device, and a welding deformation correction device. The welding deformation correction device includes a longitudinal adjustment component. and the horizontal adjustment assembly; the longitudinal adjustment assembly includes an eccentric shaft, a ratchet wheel located at one end of the eccentric shaft, and a pressure roller located at the other end of the eccentric shaft. With the above structure, the vertical adjustment assembly and the lateral adjustment assembly can be adjusted separately so that the adjustment of the H-shaped steel can be achieved. The purpose of adjusting the correction amount, however, the all-in-one machine involved in this application still requires manual operation, and the degree of automation is relatively low. Manual adjustment and adjustment of the distance between the pressure roller and the driving wheel cannot guarantee the accuracy of the size, which will affect the correction. Effect, can not further improve production efficiency, not suitable for batch correction
