Induction heating straightening device and process for welding and forming T-shaped beam

Abstract

The invention discloses an induction heating straightening device and process for welding and forming a T-shaped beam. The device comprises an induction heating power supply, a water-cooling copper pipe induction device, a moving vehicle and a workbench; the moving vehicle comprises a chassis, an upright post and a cross beam, wherein the upright post is fixed on the chassis, the cross beam is arranged on the upright post through a transmission mechanism, and a bolt is arranged on the cross beam and is used for connecting the cross beam and the water-cooling copper pipe induction device; the induction heating power supply is placed on the chassis of the moving vehicle; and the transverse and longitudinal movement of the water-cooling copper pipe induction device can be realized through thecross beam by means of the transmission mechanism. The induction heating straightening device and process solve the technical problems that the deformed T-shaped beam is straightened after welding, the production working hours and the process complexity are increased, and the increase of the manufacturing cost is caused in the prior art, thus greatly saving the working hours and the labor cost, and improving the production efficiency.

Description

technical field [0001] The invention relates to an induction heating straightening process for T-beam welding. Specifically, induction heating is adopted to conduct induction heating on the top of the web when the T-beam is formed and welded, and the top and bottom of the web are heated at the same time. The principle of symmetrical deformation straightens the T-beam. Background technique [0002] In shipbuilding, bridges, marine engineering, steel structures, etc., T-beams are an important component. Usually the T-beam is formed by welding a web and a flange. When welding, the flange is placed flat on the workbench or production line, and the web is vertically placed on the center line of the flange. Submerged arc welding or other shielded welding is used. And other processes simultaneously carry out welding production from both sides of the bottom end of the web. [0003] Most T-beams are much longer than they are wide and tall, and are in the shape of slender rods. Dur...
