Truss welded steel bar welding mechanism

Abstract

The invention discloses a truss welded steel bar welding mechanism. The truss welded steel bar welding mechanism comprises a support, a truss steel bar feeding end of the support is a front section, and a truss steel bar output end of the support is a rear section; a fixing platform is fixed to the front section of the support, an upper welding supporting assembly used for supporting a truss is installed on the upper surface of the front end of the fixing platform, and web member rib positioning assemblies are symmetrically arranged on two sides of the upper welding supporting assembly; an upper welding mechanism is installed above the adjustable upper welding supporting assembly, and the upper welding mechanism moves vertically through a height adjusting mechanism; a lower welding mechanism used for welding truss lower chord ribs is installed at the rear end of the fixing platform, and an upper chord rib pressing assembly is installed at the front end of the upper portion of the lowerwelding mechanism; and an anti-magnetization guide assembly is installed on the rear section of the support, and an anti-lateral-bending assembly is arranged above the anti-magnetization guide assembly. The truss welded steel bar welding mechanism is high in welding efficiency, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to the field of truss production, in particular to a truss welding steel bar welding mechanism. Background technique [0002] A truss is a group of components that form a triangle or a combination of several triangles in a specific way. Usually, these trusses are welded by steel bars. Reinforced trusses use steel bars as structural materials, which are welded, cut into long sections, and handed over for use. The cross-section of the steel truss is triangular, and the whole includes an upper chord bar located at the top corner and two lower chord bars located at the two bottom corners, while the two waists are two abdominal bars bent in a wave shape. The wave-shaped peaks and troughs of the abdominal bars are respectively The upper chord and the lower chord are welded together to form a whole steel truss; sometimes, due to engineering needs, it is necessary to fold up the protruding feet of the lower chord and the trough of the ab...

Problems solved by technology

[0003] In the prior art, the welding efficiency of the welding mechanism of the truss is low. The truss is welded and formed in the order from front to back. During the welding process, the welding torch is fixed. During the welding process, the electrodes are placed on other parts of the The mechanism is easy to disperse the current, the electrode loss is large, the effective utilization rate is low, and the production efficiency is low; in addition, the truss is transmitted and welded through the transmission mechanism, so that when the unwelded part is welded, the front end has been welded. Deformation occurs, resulting in unqualified finished products and reducing production efficiency
