An extruded steel bar automatic feeding and straightening mechanism

Abstract

The invention discloses an extruding type reinforcing steel bar automatic feeding and straightening mechanism, which comprises a support, wherein the support is fixedly provided with a connecting rod for being connected with a driving device; the driving device drives a straightening mechanism to reciprocate back and forth by virtue of the connecting rod; the support is internally provided with slide carriages, a plurality of palm pressure blocks are arranged among the slide carriages in a sliding manner, the palm pressure blocks surround a reinforcing steel bar which penetrates through the straightening mechanism, one end of each palm pressure block faces the reinforcing steel bar, the other end of each palm pressure block is connected with a camshaft, and each camshaft rotates to drive the corresponding palm pressure block to slide between the slide carriages so as to extrude or loosen the reinforcing steel bar; each camshaft is fixedly provided with a gear, the support is provided with rack slide block, each rack slide block is internally provided with a rack in a sliding manner, the racks are meshed with the gears on the camshafts, and the camshafts are driven to rotate when the racks and the gears generate relative motion. The straightening mechanism adopts extruding type straightening, friction loss of components can be effectively reduced, the palm pressure block action is automatically controlled while the reinforcing steel bar is fed, and the extruding type straightening and feeding of the reinforcing steel bar is completed.

Description

technical field [0001] The invention relates to the field of steel bar processing, in particular to an extrusion-type automatic feeding and straightening mechanism 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 diff...

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
