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 other 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. In the development of pipe bending machine, pipe bending machine power source has been constantly improve and improve, in the early days of the manual bending pipe material of main power is single or multiple operator of the workforce and processed products are generally small pipe fittings, such way of processing production efficiency, accuracy is not enough, tube co., LTD.
1. 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 integrated control of motor and liquid. The hydraulic pipe bender powered by hydraulic pressure is a new type of pipe bender, which has the advantages of reasonable structure, convenient operation, safe operation, quick loading and unloading and multi-use in one machine.
2, motor hydraulic hybrid drive
Although the hydraulic elbow has the advantages of large power transfer, high control accuracy, fast response speed, but also has some shortcomings, such as: because the manipulator action is too much, the production efficiency; Machine loss is large, the service life is shortened; It needs more operators, higher labor costs and higher product costs. Therefore, in the further study, the motor hydraulic hybrid drive is proposed, which can reduce production costs, improve production efficiency and improve machining accuracy by using the most reasonable drive mode in the respective advantages of the motor and hydraulic.
3, motor drive
Today's modern industry, the power source of most institutions and devices are driven by motor, providing power for the basic action of the whole device. The motor provides the source power, 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.
