With the development of modern technology, the improvement of the industrial level, the development and research of CNC numerical control pipe bending machine, three-dimensional hydraulic pipe bender and so on some high-performance pipe bender, the main driving methods of these high-level pipe bender generally have three kinds: motor drive, hydraulic drive, motor hydraulic hybrid drive.

1. Motor drive

Today's modern industry, most of the institutions and equipment are powered by motor drive method, for the basic action of the entire equipment supply power. The source power is supplied by the motor, and there are many ways in the transmission process of power, such as the motor can drive the gear, rack, CAM, connecting rod and other institutions, according to the situation of the design to meet the requirements of the bender.

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, has entered a new stage of development. Hydraulic transmission and control system is widely used in all walks of life for its advantages of large power transfer, control accuracy, fast response speed and easy to realize the integration of motor and hydraulic control. Hydraulic pipe bending machine powered by hydraulic pressure is a new type of pipe bending mechanism, which has the advantages of reasonable structure, convenient operation, safe operation, quick loading and unloading and multi-use in one machine.

3, motor hydraulic hybrid drive

Although the hydraulic elbow has the advantages of large power transfer, high control accuracy and fast response speed, it also has some shortcomings, such as: because the manipulator action is too much, the production power bottom; Machine loss is large, service life is shortened; The need for more operators, labor costs are larger, higher product costs. Therefore, the use of motor hydraulic hybrid drive is proposed in further research, which can use the most reasonable driving method to reduce production costs, improve production power and improve processing accuracy in the respective advantages of motor and hydraulic.
