Spinning type reinforcing steel bar automatic straightening machine

Abstract

The invention discloses a spinning type reinforcing steel bar automatic straightening machine. The spinning type reinforcing steel bar automatic straightening machine comprises a machine frame and a drive device, wherein a straightening mechanism driven by the drive device is arranged on the machine frame, the straightening mechanism comprises at least one set of inclined rotating idler wheels, each set of inclined rotating idler wheels are composed of a plurality of inclined rotating idler wheels making contact with a reinforcing steel bar, the inclined rotating idler wheels are sequentially arranged in the axial direction of the reinforcing steel bar, the inclined rotating idler wheels in the same set are evenly distributed on the radial periphery of the reinforcing steel bar in the circumferential direction, the inclined rotating idler wheels incline relative to the axial direction of the reinforcing steel bar, and the drive device drives the inclined rotating idler wheels to rotate and to straighten and convey the reinforcing steel bar. The spinning type reinforcing steel bar automatic straightening machine is reasonable in structure, capable of effectively straightening and automatically conveying the reinforcing steel bar at the same time, and good in straightening effect.

Description

technical field [0001] The invention relates to the field of steel bar processing, in particular to a spinning type automatic straightening machine for steel bars. Background technique [0002] At present, the steel bars used in construction projects are usually first cut by straightening and cutting the disc-shaped steel bars produced by the steel factory, and then bent into the required shape before they can be used. The current common straightening methods are: 1), use horizontal and vertical pressure rollers to straighten the steel bars, this method cannot effectively straighten the universally twisted steel bars; 2), use the rotating frame to set the rollers to straighten the steel bars , this method is disclosed in the patent document "CN200520102272.9-straightening roller device", and the rollers in the rotating frame can be used to effectively straighten the steel bars in multiple directions, but this method automatically feeds the steel bars and different wire diame...

Problems solved by technology

The current common straightening methods are: 1), use horizontal and vertical pressure rollers to straighten the steel bars, this method cannot effectively straighten the universally twisted steel bars; 2), use the rotating frame to set the rollers to straighten the steel bars , this method is disclosed in the patent document "CN200520102272.9-straightening roller device", and the rollers in the rotating frame can effectively straighten the steel bars in multiple directions, but this method automatically feeds the steel bars and different wire diameters It is inconvenient to straighten the steel bar, and the straightening effect is not ideal; 3), use the straightening block arranged in the rotating adjustment cylinder to straighten the steel bar, this method is described in the patent document "CN200520102271. It is disclosed in "Straightening Cylinder" that the straightening block in this method has great friction damage to the surface of the steel bar and the noise is large, and because of the large friction, the straightening block wears out quickly, resulting in many wearing parts and heavy operating costs. Automatic feeding and efficiency Neither is ideal
