U rib plate unit one-side welding double-side forming device and forming method thereof

Abstract

The invention discloses a U rib plate unit single-side welding and double-side forming device and a forming method thereof, the U rib plate unit single-side welding and double-side forming device is used for welding and forming a U rib plate unit, and the U rib plate unit single-side welding and double-side forming device comprises a bearing table, a portal frame and a welding mechanism; the bearing table is used for placing a bridge deck slab to be welded and a U-shaped rib plate; the portal frame is erected above the bearing table in the first horizontal direction and can move in the second horizontal direction, a transverse moving seat capable of moving in the first horizontal direction is arranged on a cross beam of the portal frame, and the transverse moving seat is provided with a longitudinal moving frame capable of moving in the vertical direction; the welding mechanism comprises two welding assemblies arranged on the two sides, in the first horizontal direction, of the longitudinal moving frame respectively, each welding assembly comprises a welding gun and an electrode holder, gun handles of the welding guns are arranged on the longitudinal moving frame, nozzles of the welding guns are used for facing the weld joints on the corresponding sides, the electrode holders are used for clamping welding rods, and the ends of the welding rods are arranged at the weld joints on the corresponding sides. The welding tongs are movably arranged on the longitudinal moving frame so that welding rods can swing in the width direction of welding seams on the corresponding sides, and therefore single-face welding and double-face forming can be achieved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a U-rib unit single-sided welding double-sided forming device and a forming method thereof. Background technique [0002] U-rib unit is the most numerous type of unit element in bridge projects. In order to produce U-rib unit on a large scale, U-rib unit production line is usually used for mass production. The U-rib unit is formed by welding the bridge deck and a plurality of U-ribs. During the welding process, the use of traditional double-sided welding is not only unfavorable for welding forming and reducing the welding quality, but also inconveniences the operator and increases the difficulty of welding. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to propose a U-rib unit single-sided welding double-sided forming device and its forming method, aiming to solve the problem that the U-rib unit is formed by double-sided welding, which ...
