Side bending prevention device of truss welding production line

Abstract

The invention discloses a side bending prevention device of a truss welding production line. The side bending prevention device is located above a lower welding electrode on one side of an upper welding electrode and structurally characterized in that a trapezoid tank is formed in the bottom of a strip-shaped bending prevention template and inserted in two sides of an upper rotary rib and two sides of a web bar, the bending prevention template is flexibly connected to a bending prevention main plate located on the bending prevention template, the bending prevention main plate is fixed in an adjusting rack, and the upper end of the adjusting rack is fixed to a lifting rack; an adjusting mechanism for adjusting the position of the bending prevention main plate is arranged on the adjusting rack, the bending prevention main plate and the bending prevention template are equally long, two side faces at the two ends of the bending prevention main plate are provided with a pair of limiting plates respectively, the two pairs of the limiting plates are symmetrical in position, and the two ends of the bending prevention template are limited between the each pair of the limiting plates respectively. The side bending prevention device has the advantages of being novel in structure, convenient to adjust and reliable, saving production cost, lightening labor intensity, preventing rebar from being laterally bent, and ensuring that a welded truss is attractive and is not bent.

Description

technical field [0001] The invention relates to a truss welding production line, in particular to an anti-side bending device for a truss welding production line. Background technique [0002] At present, the straightness of the truss after welding by the truss welding production line is poor. There are many reasons for the poor straightness of the truss. When the lower electrode is welding the lower rebar and cladding rebar, the welding pressure on both sides of the welding point is different, causing deformation. When the truss moves to the upper electrode with the production line, the upper electrode continues to weld on the basis that the above deformation has not been adjusted. The deformation of the truss is intensified after the upper electrode is welded and tightened and the reinforcement is covered, resulting in side bending of the truss. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned...
