[0002] In the construction of cement concrete structures, it is usually necessary to add steel bars to improve the tensile properties of cement concrete. Due to the structural force requirements, it is usually necessary to bend straight steel bars. The steel bars are bent in the middle or in two sections to make the steel bars complete a specific shape or have hooks. Cold bending of steel bars is a common construction process in steel bar processing projects. When bending steel bars on site, it is necessary to use a steel bar bending machine to bend the steel bars according to the shape of the steel bars, but the current steel bar bending machines are usually expensive, and the transportation and installation processes are cumbersome. When the commonly used steel bar bending machine bends the steel bars to different angles, it is necessary to replace the bending device or change the bending procedure, which brings many inconveniences to the steel bar bending process.
