Welding positioning device for steel bars for building construction

Abstract

The invention relates to a welding positioning device for steel bars used in building construction to solve the problem of frequent disassembly of the device in the process of electroslag pressure welding of steel bars, different diameters of steel bars after installation and clamping, out of axis, and pressure upsetting due to construction workers' operations. The quality problem of the steel bar after welding caused; the present invention comprises the fixed bar that axis is arranged vertically, and the first arc-shaped frame and the second arc-shaped frame are connected on the fixed bar, and the first centering clip is arranged on the first arc-shaped frame Tightening mechanism, welding distance adjustment mechanism and control system, the second centering clamping mechanism is set on the second arc frame, and the opening and closing mechanism of the conductive agent box is set on the fixed rod. By adjusting the welding distance adjustment mechanism, different diameters can be solved. To solve the problem of different welding distances of steel bars, adjust the motor speed switch and adjust the pressure upsetting time of steel bars with different diameters. During the pressure upsetting process, the quality problems of steel bar welding caused by workers' operation problems are effectively avoided.

Description

technical field [0001] The invention relates to the field of steel bar welding, in particular to a welding positioning device for steel bar for building construction. Background technique [0002] In the welding of steel bars in the construction field, commonly used steel bar welding methods include flash butt welding, arc welding, electroslag pressure welding, resistance spot welding and steel bar pressure welding. Electroslag pressure welding is mostly used for vertical steel bars in cast-in-place reinforced concrete structural members. Take it long. The use method of prior art electroslag pressure welding: put a small piece of conductive agent (steel wire bead, electric welding rod, etc.) The arc is ignited and burned by the circuit. After the slag pool is formed, the steel bar is melted and the arc is stabilized for a certain period of time, while the power is turned off, the manual pressurization mechanism is used for pressurized upsetting to remove slag inclusions and...
