Description

A steel bar feeding device for steel bar truss production

Technical Field

The utility model relates to the technical field of truss production, in particular to a steel bar feeding device used for steel bar truss production.

Background Art

Steel trusses refer to trusses made of steel. The roof structures of industrial and civil buildings, such as crane beams, bridges and hydraulic gates, often use steel trusses as the main load-bearing components. Various towers, such as mast towers, TV towers and transmission line towers, often use spatial steel trusses composed of three-sided, four-sided or multi-sided plane trusses. In the prior art, there are already mature production technologies for various types of steel trusses, but most production processes still have some defects in feeding. In the existing feeding process, most feeding devices use intermittent structures to transport a single steel bar to the placement slot. When the steel bar enters the placement slot, it slides into the placement slot. Because the length of the steel bar is too long, during the sliding process, the two ends of the steel bar will have a certain swing. The swing amplitude is too large, which will cause certain damage to the equipment, and the steel bar is inconvenient to take in the next process in the placement slot. For this reason, a steel bar feeding device for steel truss production is proposed to solve the above problems.
