Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] A method for assembling and welding H-shaped steel, the method comprising the following steps:

[0025] ①. Pre-assembled

[0026] refer to image 3 , in the pre-assembly step, at first two flange steel plates 1 as the H-shaped steel flange and a web steel plate 2 as the H-shaped steel web are placed flat on the pre-assembled conveying roller table, wherein the two flange steel plates 1 are respectively located on both sides of the web plate 2;

[0027] Afterwards, the two wing plate steel plates 1 are turned over 90° to make them stand sideways, the web plate steel plates 2 are lifted up, and the side plate steel plates are moved to the still horizontally laid web steel plates, so that the side standing wing plate steel plates are aligned with the The web steel plates are leaned against each other, thus pre-assembled into an...

Abstract

The invention discloses an assembling welding forming method of H-shaped steel. The assembling welding forming method is characterized by comprising the following steps that 1, pre-assembly is performed; 2, spot welding is performed so that an H-shaped steel frame can form a preliminary whole; 3, seam abutting and full-length welding are performed; and 4, deformed workpieces after welding are straightened by an H-shaped steel straightening machine in the forward conveying process of the workpieces, so that the qualified H-shaped steel is completed. The assembling welding forming method of theH-shaped steel has the beneficial effects that the H-shaped steel adopts a horizontal placement mode during welding forming, the forming steps are smooth, and assembly line work can be realized; and at the same time, at least one pair of submerged arc welding machines are arranged on both sides of a welding transfer roller bed, and according to the working conditions of the submerged arc welding machines, the workpieces are sent to the submerged arc welding machine which is available for welding, the production cycle is compact, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a method for assembling and welding H-shaped steel. Background technique [0002] In the prior art, the splicing and welding of H-beams such as figure 1 , figure 2 As shown, the vertical welding method is adopted: first lay the first wing plate flat, then put the web upright and put it on the wing plate, and weld at the junction of the two to form a T-shaped workpiece a; after that Lift the T-shaped workpiece a and turn it over 180°, put the web in the T-shaped workpiece a onto another wing plate, and then weld the seam. This H-shaped steel forming method in the prior art is very troublesome. Contents of the invention [0003] In order to overcome the disadvantage of troublesome forming of the H-shaped steel in the prior art, the present invention provides a method for assembling and welding the H-shaped steel which is easy to form. [0004] The technical solution of the present invention to solve the technical problem i...
