Therefore, in order to ensure the quality, safety and stability of the steel bars during later use, it is necessary to properly and reasonably process these steel bars during construction. One of the processes is to use mechanical equipment to bend and shape the steel bars so that they meet the requirements of the design drawings.

[0003] However, some problems were found in the actual operation process. For example, the existing equipment for bending steel bars has a large angle value that needs to be manually adjusted during use, resulting in low production efficiency of the entire equipment; at the same time, when performing multiple bending operations on steel bars of different diameters, the angle data needs to be readjusted before continuing to work, which increases the workload of the staff and affects the work efficiency. Therefore, a steel bar fixed-angle bending device based on a PLC control system is proposed to solve the above problems. Summary of the invention
