[0002] Steel bar bending refers to the process of bending steel bar according to design requirements. According to the different bending parts and angles, steel bar bending can be divided into various types, such as arbitrary angle bending of non-end and 90-degree bending for anchoring of end, etc.
[0003] In building engineering, cement pouring needs to be carried out on the roof. In this step, steel bars need to be laid for assisting the tensile strength of concrete slab and reducing plastic deformation. However, in order to ensure that the steel bars can be fully laid, the steel bars are often reserved to be too long. Before the cement pouring, the excess steel bars need to be bent.
[0004] When bending the steel bars, a manual bending machine is generally used, which mainly consists of a workbench, a steel bar clamping groove, a bending column and a manual bending plate. During operation, the operator inserts the steel bar into the steel bar clamping groove and slowly pushes it out. A ruler is used to measure the length and angle of bending on the workbench, and then the handle is moved to bend and form. However, this operation is very tedious and not very convenient to use, resulting in low efficiency, waste of manpower, and the bending does not reach the ideal effect, which easily causes fatigue to the operator.
