With the development of modern technology and the improvement of industrial level, CNC numerical control bending machine, three-dimensional hydraulic bending machine and other high-performance bending machines are developed and discussed. The main driving methods of these high-level bend benders are generally three: motor drive, hydraulic drive and motor hydraulic hybrid drive.
1. Motor drive
In modern industry today, the power source of most mechanisms and equipment are driven by motor, which provides power for the basic action of the whole equipment. The power is supplied by the motor. In the process of power transmission, there are many ways. For example, the gear, rack, cam, connecting rod and other mechanisms can be driven by the motor, and the pipe bending machine meeting 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 system is widely used in all walks of life because of its advantages of high transmission power, high control precision, fast response and easy to realize the integration of motor and hydraulic control. The hydraulic pipe bender powered by hydraulic pressure is a new type of pipe bender. It has the advantages of reasonable structure, convenient operation, safe operation, fast loading and unloading and multi-purpose.
3. Motor hydraulic hybrid drive
Although the hydraulic elbow has the advantages of high power transmission, high control precision and fast response speed, it also has some shortcomings, such as: because the operator acts too much, the output power is low; Large machine loss and short service life; 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 use the most reasonable drive method to reduce the production cost, improve the production power, and improve the processing accuracy.
