With the development of modern technology and the improvement of the industrial level, the development and research of CNC numerical control pipe bender, three-dimensional hydraulic pipe bender and other high-performance pipe benders, these high-level pipe benders are generally driven by three main driving methods: motor drive, hydraulic drive, motor hydraulic hybrid drive.
1. Motor drive In today's modern industry, most of the power sources of mechanisms and equipment use motor drive methods to provide power for the basic actions of the entire equipment. The motor provides the source power, and there are many ways to transmit the power, such as the gear, rack, cam, connecting rod and other mechanisms can be driven by the motor, and the pipe bender that meets the requirements is 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 machinery and equipment, especially in recent years, it has entered a new stage of development. The hydraulic transmission and control system is widely used in all walks of life because of its advantages of large transmission power, control accuracy, fast response speed and easy to realize the integrated control of motor and hydrum. The hydraulic pipe bender powered by hydraulic pressure is a new type of pipe bending mechanism, which has the advantages of reasonable structure, convenient operation, safe operation, fast loading and unloading and multi-purpose of one machine. 3. Motor-hydraulic hybrid drive Although the hydraulic elbow has the advantages of large transmission power, high control accuracy and fast response speed, it also has some shortcomings, such as: because the operator has too many actions, the output power is low; The machine has large wear and tear and shortens the service life; The required operators are large, the labor cost is large, and the product cost is high. Therefore, in further discussion, it is proposed to adopt motor-hydraulic hybrid drive, so that the most reasonable driving method can be used to reduce the production cost, increase the production power and improve the machining accuracy in the respective advantages of the motor and hydraulic.
