Turnover welding and molding production line of H profile steel

Abstract

The invention discloses a turnover welding and molding production line of H profile steel. The turnover welding and molding production line comprises a longitudinal material duct and a transverse conveying material duct which are used for guiding the H profile steel, wherein the longitudinal material duct and the transverse conveying material duct are respectively connected with a hydraulic power device and an electric control device. The production line also comprises a connection plate positioning device and turnover welding molding devices, wherein the turnover welding molding devices are connected with the hydraulic power device and the electric control device; a longitudinal positioning device is arranged on the longitudinal material duct; a lifting device and the transverse positioning device are arranged on the transverse conveying material duct; and the turnover welding molding devices can turn over randomly in an angle of 360 DEG. In the work, the length and the position of a positioning swing arm of the connection plate positioning device and a distance between the two turnover welding molding devices are adjusted according to the model number of the H profile steel and the position of the connection plate to be welded; the H profile steel is held and clamped tightly; the position of the connection plate is adjusted and fixed so as to carry out spot welding; the H profile steel turns over the angle of 180 DEG; and the welding work is carried out repeatedly. At the time, the overall welding procedure is finished, and the next procedure begins.

Description

[0001] Technical field [0002] The invention relates to the technical field of section steel welding equipment, in particular to a welding production line for H section steel connecting plates. Background technique [0003] H-shaped steel has the advantages of strong bending resistance, simple construction and cost saving. It has been widely used as building materials in industries such as construction, bridges, tower masts and grid frames. H-shaped steel is used as the main beam component in the three-dimensional garage industry. It is necessary to weld a connecting plate with a length of 300-400mm on the plane parallel to the web of the H-beam. The welding is mainly performed by manual positioning. The manual placement is used for rough positioning, poor consistency, and takes up more labor resources, increasing production Cost and low production efficiency. In order to ensure the welding quality of the H-shaped steel and the connecting plate, it is necessary to flip the H-sha...

[0003] H-shaped steel has the advantages of strong bending resistance, simple construction and cost saving. It has been widely used as building materials in construction, bridges, towers, grids and other industries. H-shaped steel is used as the main beam component in the three-dimensional garage industry. It is necessary to weld the connecting plate with a length of 300-400mm on the plane of the H-shaped steel parallel to the web plate. The welding is mainly performed by manual positioning, which is rough and poor in consistency, and takes up more labor resources, which increases production. cost and low production efficiency

In order to ensure the welding quality of the H-shaped steel and the connecting plate, it is necessary to turn over the H-shaped steel during welding. Because the volume and weight of the H-shaped steel are very large, it is very difficult to turn over the H-shaped steel during welding. At present, manual methods are often used to turn over the H-shaped steel. Section steel needs to be operated by a crane, which not only has low work efficiency, but also has poor safety and is prone to accidents
