The structural principle of medium frequency pipe bending ma

Medium frequency pipe bending machine is a kind of equipment used for metal processing, mainly used for bending pipes and pipe fittings. It consists of a number of components, including a spindle, a bend frame, a transmission system, a hydraulic system and a control system. Below I will introduce the structural principle of medium frequency pipe bending machine in detail.

### 1. Spindle

The spindle of the medium frequency pipe bender is one of the core parts of the whole equipment, which is responsible for the bending of the pipe. Spindles are usually made of high-strength alloy steel with good rigidity and wear resistance. The main shaft is equipped with a bending mold, which can be replaced with different specifications according to needs to adapt to different diameters and thicknesses of pipes.

### 2. Bend pipe rack

The bend frame is a frame structure that supports and holds the spindle, and is usually assembled by welding or bolting. The bending frame has good rigidity and stability, and can withstand the strong force and torque generated in the bending process. The pipe bender frame is also equipped with a guide device to ensure the accurate positioning and movement of the pipe during bending.

### 3. Drive system

Transmission system is the power source of medium frequency pipe bending machine, which is mainly composed of motor, reducer and transmission device. The motor outputs constant speed and torque through the reducer, and the transmission device transmits power to the spindle to drive the tube for bending processing. The transmission system usually has a variable speed function, which can adjust the speed and torque as needed to adapt to the processing needs of different workpieces.

### 4. Hydraulic system

The hydraulic system is used to control the bending action and processing force of the pipe bender system, which is mainly composed of hydraulic pump, oil tank, hydraulic cylinder and control valve. By adjusting the working pressure and flow of the hydraulic cylinder, the hydraulic system realizes the accurate bending of the pipe and maintains the stability of the bending Angle. The hydraulic system also has loop control and protection functions to ensure the stable operation of the equipment.

### 5. Control system

The control system is the automatic core of the medium frequency pipe bending machine, which is mainly composed of PLC controller, man-machine interface and sensor. The control system can realize the automatic control and monitoring of the pipe bending machine, including setting machining parameters, adjusting working mode, real-time monitoring of the machining process and alarm. The control system can also store and manage process data, improving production efficiency and product quality.

In general, the medium frequency pipe bending machine is an efficient and precise metal processing equipment, with simple structure, easy operation and high processing accuracy. Through reasonable structural design and advanced control technology, the medium frequency pipe bender can realize the bending processing of various pipes, which is widely used in automobile manufacturing, aerospace, ship construction and other fields, providing important technical support for industrial production.
