An automatic welding device for h-shaped steel

Abstract

The invention relates to the field of steel structure processing, in particular to an H-shaped steel automatic welding device which comprises a working table, an overturning mechanism, an automatic welding mechanism and a limit mechanism. Two limit jigs can be movably arranged at the top of the working table at intervals, and the automatic welding mechanism comprises a welding component, a liftingcomponent, a rectangular mounting plate and two lead screw sliding tables. The H-shaped steel automatic welding device has the advantages that two edges of H-shaped steel can be simultaneously weldedby the automatic welding mechanism, the position of the H-shaped steel cannot be additionally adjusted by a worker, the H-shaped steel can be conveniently welded by the worker and automatically limited by the limit mechanism, so that offset of the H-shaped steel is omitted in the welding process, the H-shaped steel can be automatically overturned by the overturning mechanism, manual overturning of the worker is omitted, and the labor intensity of the worker is reduced.

Description

technical field [0001] The invention relates to the field of steel structure processing equipment, in particular to an automatic welding device for H-shaped steel. Background technique [0002] H-shaped steel is composed of two wings and one web, and has an H-shaped cross-sectional shape; H-shaped steel has the advantages of ideal cross-sectional area distribution and reasonable strength-to-weight ratio, so it has stronger bending resistance than I-shaped steel. Under the same cross-sectional load, H-shaped steel has the characteristics of lower weight than traditional structural steel. The traditional welding method is to place the web horizontally first, and then fix the vertical wing plate in the middle before welding. After welding, the other Weld on both sides of one side. This welding method has many steps, low efficiency, and low degree of automation, and long-term work will bring greater labor intensity to workers. [0003] The patent No. CN107378330A is an inventi...

Problems solved by technology

[0004] Although this invention can weld two H-shaped steels at the same time, it is difficult to weld both sides of an H-shaped steel at one time in this patent, requiring workers to manually change the positions of the H-shaped steels, which brings great trouble to the workers ; Although this patent can lack the fixing device for the H-shaped steel, it is easy to shake or shift the H-shaped steel in the welding process, which affects the success rate of the H-shaped steel welding, and makes the H-shaped steel have a safety hazard of being scrapped; this patent can only One side of the H-shaped steel is welded, and both sides of the H-shaped steel need to be welded, so that the worker needs to manually turn over the H-shaped steel, which will bring greater labor intensity to the worker.
