A press-fit steel bar straightening machine

Abstract

The invention discloses a novel press fit type reinforcement bar straightening machine. The novel press fit type reinforcement bar straightening machine comprises a guide-in mechanism and a press fit type straightening mechanism. The guide-in mechanism comprises at least one set of active guide wheels. The press fit type straightening mechanism comprises a fixed support. A plurality of pressing block devices are arranged in the fixed support and surround penetrating reinforcement bars in the radial direction. The pressing block devices are connected with camshafts in a penetrating mode, and the camshafts are connected with a drive device and rotate to drive the pressing block devices to slide in the fixed support in the radial direction to extrude or loosen the reinforcement bars. Limiting blocks are arranged at the ends, facing the reinforcement bars, of the pressing block devices and provided with arc-shaped grooves. The limiting blocks on the different pressing block devices are arranged in an alternating mode in the longitudinal direction. Every two adjacent limiting blocks are attached together. The novel press fit type reinforcement bar straightening machine is simple in structure. The guide-in mechanism conveys the reinforcement bars into the press fit type straightening mechanism, the press fit type straightening mechanism straightens the reinforcement bars in an intermittent extrusion mode, the straightening process is fast and effective, and frictional loss is avoided.

Description

technical field [0001] The invention relates to the field of steel bar processing, in particular to a press-fit steel bar straightening machine. Background technique [0002] At present, the steel bar components used in construction projects are usually first cut by straightening and cutting the disc-shaped steel bars produced by the steel mill, and then bent into the desired shape before application. The current common straightening methods are: 1) Use horizontal and vertical pressing wheels 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", the use of rollers in the rotating frame can effectively straighten the steel bars in multiple directions, but this method automatically feeds the steel bars and adjusts different wire diameters. The straighten...
