Description

Reinforcing steel bar straightening machine Technical Field The utility model relates to the technical field of steel bar machining, in particular to a steel bar straightening machine. Background The steel bar is used as an indispensable reinforcing material in the construction engineering, and the processing precision of the steel bar directly influences the bearing performance and the construction efficiency of the concrete structure. In the processing flow of the steel bar, straightening correction is one of key procedures, and aims to eliminate bending deformation of the steel bar caused by transportation or storage so as to meet the requirement of straightness. However, the conventional steel bar straightening device still has a significant technical bottleneck in practical application: The adaptability and stress defect of the straightening mechanism are that the existing straightening machine adopts rollers in a single direction or pressure heads with fixed intervals to squeeze and straighten the steel bars, and the straightening heads are fixed in position and can only be adapted to the steel bars with specific diameter ranges. For reinforcing steel bars with different specifications (such as phi 6mm to phi 20 mm), the roller spacing is manually adjusted or the die is replaced, so that the operation is complex and the efficiency is low. The power dependence and the material conveying efficiency are insufficient, namely the material conveying mechanism of the traditional equipment is mostly dependent on a conveying belt or a chain driven by a motor, and a power source is additionally arranged, so that the energy consumption is increased, and the failure rate is increased due to the complicated mechanical structure. Especially after cutting, the steel bars need to be transferred to a stacking area manually or by a mechanical arm, and the problems of waiting for stopping or mismatching of action beats exist, so that continuous and efficient production is difficult to realize.
