Special equipment for welding steel components

Abstract

The invention discloses a special welding device for section steel members, which includes a mounting seat, a rotating column is sleeved at the middle position of the inner bottom of the mounting seat, a driven gear is provided at the middle position outside the rotating column, and a driven gear is arranged inside the mounting seat. The side of the bottom near the rotating column is provided with a servo motor B, and the output end of the servo motor B is provided with a driving gear that meshes with the driven gear; The web is fit and clamped, and as the two sets of clamping discs approach each other, the flange plates combined with the web are fitted correspondingly, so that the flange plates are well in contact with the web and positioned. The welding work can be carried out through the welding torch, and at the same time cooperate with the expansion of the positioning plate to fit the bottom of the two sets of flange plates again to form an auxiliary support. Through the multi-directional clamping and positioning structure, the contact between the flange plate and the web plate is further improved targeting performance.

Description

technical field [0001] The invention relates to the technical field of steel structure welding, in particular to a special device for welding steel components. Background technique [0002] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size. It is one of the four major types of steel. According to the cross-sectional shape, section steel is divided into simple section section steel and complex section section steel. The former refers to square steel, round steel, flat steel, angle steel, Hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc. In the processing of section steel, welding is one of the common processing methods.

Problems solved by technology

[0003] In the current H-shaped steel processing and welding process, the web and the flange are generally welded and combined to form an H-shaped steel body. However, it is difficult to position the web before it is combined with the flange plate, which increases the difficulty and inconvenience of the staff. Moreover, it is difficult to maintain a good fixing effect between the flange plate and the web after positioning, and it is easy to cause position deviation during the welding process, resulting in an increase in the processing error of the H-shaped steel frame and reducing the accuracy and pass rate of the steel welding; during the processing and welding of the H-shaped steel , it is difficult for the welding head of the welding torch to correspond to the welding joint between the web and the flange plate, and it is not easy to maintain a balance to carry out welding seam splicing at the joint of the section steel, which reduces the difficulty of welding the H-section steel components and reduces the work efficiency of the operator. During the welding of section steel, it is often necessary to turn over the whole welded H-section steel on one side before welding the other side. The existing overturning operation generally lifts and turns the H-section steel by a sling, which not only makes the H-section steel It is difficult to maintain balance when lifting, and it is prone to damage such as knocking, and the operation often involves repeated contact with the positioning of the H-shaped steel, which increases the workflow of the operator and reduces the welding efficiency of the steel components.
