With the development of modern technology and the improvement of industrial level, some high-performance pipe bending machines such as CNC numerical control pipe bending machine, three-dimensional hydraulic pipe bending machine, etc. have been developed and discussed. The main driving methods of these high-level pipe bending machines are generally There are three types: motor drive, hydraulic drive, and motor-hydraulic hybrid drive.

1. Motor drive

In today's modern industry, the power source of most mechanisms and equipment adopts the motor drive method to provide power for the basic movement of the entire equipment. The source power is supplied by the motor, and there are many methods in the power transmission process. For example, the gear, rack, cam, connecting rod and other mechanisms can be driven by the motor, and the pipe bending machine that meets the requirements can be designed according to the situation.

2. Hydraulic drive

With the continuous development of industrial technology, hydraulic transmission technology is one of the fastest developing technologies in mechanical equipment, especially in recent years, it has entered a new stage of development. Hydraulic transmission and control systems are widely used in all walks of life due to their advantages of large transmission power, high control accuracy, fast response speed and easy realization of motor-hydraulic integrated control. The hydraulic pipe bending machine powered by hydraulic pressure is a new type of pipe bending mechanism.

3. Motor-hydraulic hybrid drive

Although the hydraulic elbow has the advantages of high transmission power, high control precision and fast response speed, it also has some shortcomings, such as: because the operator moves too much, the output power is low; the machine loss is large, and the service life is shortened; There are many operators, labor costs are high, and product costs are high. Therefore, in the further discussion, it is proposed to use the motor-hydraulic hybrid drive, so that the most reasonable driving method can be used in the respective advantages of the motor and the hydraulic pressure to reduce the production cost, improve the production power and improve the machining accuracy.
