With the continuous development of my country’s economic construction, pipe benders are essential equipment in modern industry and are widely used. The demand for pipe benders in transportation and infrastructure construction is increasing. The efficiency of pipe benders is increasing. Precision and degree of automation also put forward higher requirements, and the use of PLC system to control the pipe bender can better realize the processing needs of customers.

Automatic pipe bender is mainly composed of mechanical parts, hydraulic system and PLC control system. The PLC control system of the automatic pipe bender is small in size, complete in functions and high in reliability. In order to make the product stable and easy to maintain, we adopt a control system with PLC as the main controller on the pipe bender.

This kind of automatic tube bender control system consists of human-machine interface (HMI), programmable controller (PLC), servo motor, oil cylinder, etc. The control system uses PLC as the core controller and the touch screen as the operating terminal. PLC accepts operation control on the touch screen and control signals such as the position signal and bending angle of the hydraulic cylinder, so that the hydraulic cylinder operates in a prescribed order. On the one hand, the touch screen transmits the operation control signals and parameters of the pipe bender to the PLC; on the other hand, it displays the PLC control results and operating information on the touch screen to realize dynamic monitoring during the production process. When a fault occurs, the touch screen will switch to the alarm interface, displaying the fault information, which is convenient for fault handling.


Our country's pipe bending machine manufacturing technology is constantly advancing, with advanced pipe bending machines, its product structure is more and more reasonable, and the quality is getting higher and higher.
