Welding device for building reinforcing steel bar precise localization

Abstract

The invention discloses a welding device for building reinforcing steel bar precise localization. The welding device comprises a work platform, sliding grooves are formed in the two sides of the top end of the work platform, the two sliding grooves are in sliding connection with four sliding blocks, the four sliding blocks are fixedly arranged on the bottom end of a first stand, the bottom end ofa second stand, the bottom end of a third stand and the bottom end of a fourth stand, the first stand and the second stand are fixedly connected through a mechanical telescopic rod, and the third stand and the fourth stand are fixedly connected through a mechanical telescopic rod. According to the welding device for building reinforcing steel bar precise localization, through a grinding wheel, after heat treatment of a welding opening of reinforcing steel bars, the welding opening is ground, burrs on the welding opening are removed, and the phenomenon that during taking of the reinforcing steel bars, a worker is hurt by the burrs is avoided; a flame spraying gun is fixedly arranged on a disc, a first motor is started, the flame spraying gun and the grinding wheel can be replaced back and forth, back and forth heat treatment and preheating of the welding opening by manual work can be avoided, and work efficiency of welding is improved.

Description

technical field [0001] The invention relates to a welding device, in particular to a welding device for precise positioning of building steel bars, belonging to the technical field of building steel bar processing equipment. Background technique [0002] Building steel bars refer to various steel bars, steel wires, etc. used in reinforced concrete. Steel bars are divided into: non-alloy steel bars, low-alloy steel bars, and alloy steel bars. Steel bars are divided into: hot-rolled bars, heat-treated bars, waste heat-treated bars, cold-rolled bars, and cold-drawn bars. According to the shape, the steel bar is divided into: smooth round steel bar and deformed steel bar. Deformed steel bars are crescent rib steel bars (spiral, herringbone, with longitudinal ribs, without longitudinal ribs). The mechanical properties of steel bars are expressed in strength grades in their grades, and the unit is Mpa. [0003] At present, when welding building steel bars, it is necessary to use...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a welding device for precise positioning of building steel bars to solve the problems in the above-mentioned background technology that the precise positioning is not possible and the length of the steel bars is different, and the clamps cannot be adjusted, resulting in the problem that some steel bars cannot be fixed.
