Large hydraulic medium frequency pipe bending machine

Large hydraulic medium frequency pipe bending machine is an advanced equipment for processing metal pipes. It bends pipes into the desired shape through the linkage of hydraulic system and medium frequency heating system. The following will be introduced from three aspects: hydraulic system, intermediate frequency heating system and machine structure.

Hydraulic system is one of the core components of large hydraulic medium frequency pipe bending machine. It is composed of hydraulic pump, hydraulic valve, oil cylinder and pipeline. Hydraulic pump is a device that provides pressure and flow, which controls the action of the cylinder by driving hydraulic oil into the hydraulic valve. The hydraulic valve plays the role of distributing and controlling the hydraulic oil flow. According to the input of the control signal, it can realize the forward, backward, stop and other actions of the cylinder. The cylinder is the key component to realize the bending of the pipe. Through the telescopic movement of the cylinder, the force is applied to make the pipe bend and deform. The hydraulic pipeline connects each hydraulic component through the pipe, so that the hydraulic system forms a closed flow system.

Medium frequency heating system is another important part of large hydraulic medium frequency pipe bending machine. Through the principle of electromagnetic induction, the high-frequency current is transmitted to the surface of the pipe, and the heat is generated to make the pipe heated and softened, so that it is easy to bend. Intermediate frequency heating system is mainly composed of host, intermediate frequency power supply and induction coil. The host plays the role of controlling and monitoring the intermediate frequency heating system, the intermediate frequency power supply provides a stable high frequency current, and the induction coil conducts the current to the surface of the pipe through the principle of electromagnetic induction.

The machine structure is the external form and internal composition of the large hydraulic medium frequency pipe bending machine. The external structure includes the base, workbench and console, etc. The base plays the role of fixing and supporting the whole machine, the workbench is the area where the pipe is placed and the bending process is performed, and the console is the center of the operation and monitoring of the machine. The internal structure includes hydraulic system, intermediate frequency heating system and transmission system, etc. The hydraulic system and intermediate frequency heating system have been introduced in detail, and the transmission system includes motor, gear and transmission rod, etc., which provides power through the motor, and the gear and transmission rod transfer power to the cylinder and bending mold to realize the bending processing of the pipe.

In short, large hydraulic medium frequency pipe bending machine is a combination of hydraulic and medium frequency heating technology of high precision pipe processing equipment. Through the hydraulic system drive and control, with the intermediate frequency heating system heating softening effect, to achieve the bending of metal pipe processing. The stability of the machine structure and the reliability of the transmission system are crucial to ensure the machining accuracy and efficiency. In practical applications, large hydraulic medium frequency pipe bending machine is widely used in aerospace, automobile manufacturing, petrochemical and other fields, and has become an important tool to improve production efficiency and product quality.
