I-shaped steel welding device

Abstract

The invention discloses an I-shaped steel welding device. The device comprises a welding device body, wherein the welding device body comprises a rack; a limiting mechanism, positioning mechanisms anda welding mechanism are fixedly connected to the top of the rack; the limiting mechanism comprises vertically arranged first fixing frames; a roller is fixedly connected to the bottom of each first fixing frame; a limiting rod is fixedly connected to the top of each first fixing frame; each positioning mechanism comprises a first air cylinder, a second air cylinder and a third air cylinder; eachfirst air cylinder is arranged along the width direction of the rack; a second fixing frame is fixedly connected to the end part of each first air cylinder; a sliding table is slidably connected to the bottom of each second fixing frame; one side of each second fixing frame is fixedly connected with an output shaft of the corresponding second air cylinder through a fastener; supporting frames arefixedly connected to the two sides of the top of each second fixing frame; a cross beam is fixedly connected to the tops of the supporting frames on the top of each second fixing frame; each third aircylinder is fixedly connected to the corresponding cross beam; and end, close to the corresponding first air cylinder, of each cross beam is provided with sliding grooves. The I-shaped steel weldingdevice is simple in structure, high in automation degree, accurate in alignment, and capable of improving the working efficiency and saving the manpower.

Description

technical field [0001] The invention relates to the technical field of steel structure processing equipment, in particular to an I-beam welding device. Background technique [0002] The I-beam is a long strip of steel with a groove-shaped cross-section. It belongs to carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. I-beams are mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. In practical applications, it is often necessary to weld I-beams of different lengths together, but currently there is no mechanical equipment for efficiently welding I-beams. [0003] The I-beam is similar to the "H"-shaped steel structure, and has many common features, and the welding process also has many similarities. The patent No. CN107378330A is an invention patent for an H-shaped steel welding device, including a bracket group, guide rails, door beams and a cantilever welder. ...

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.
