Problems solved by technology

Although the existing five-head vertical steel bar bending machine has the advantages of large production capacity and high efficiency for bending stirrups, it has the following defects: the bending structure is complicated, the reducer and the gear are connected together through a coupling, and then through the gap between the gear and the gear. The transmission between the steel bars is bent, the parts of the bending machine are processed with high precision, and there is also a high requirement for coaxiality during assembly. If the coaxiality is not guaranteed, it will easily cause damage to the gears and reduce the service life of the gears; Many, low assembly efficiency, inconvenient maintenance and other defects

Description

technical field [0001] The invention belongs to the field of building construction applications, and in particular relates to a PLC-based steel bar bending machine device for building construction and a working method thereof. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. The steel bar needs to be bent into a predetermined shape before use, and the steel bar is usually bent manually or by a steel bar bending machine. [0003] The five-head vertical steel bar bending machine is an automatic equipment for bending steel bars. With the development of construction industry and transportation construction, the task of steel bar processing is becoming increasingly heavy, especially the demand for stirrups is growing very fast. Although the existing five-head vertical steel ba...
