Case

In the development of automatic pipe bending machine, the power source of the pipe bending machine has

been constantly improving and improving, in the early manual bending of pipe fittings materials, the main

power source is single or multiple manipulators of labor, the processed products are generally small pipe

fittings of the tube, such processing production efficiency bottom, precision is not enough, tube type is

limited. With the development of modern technology and the improvement of industrial level, the

development and research of CNC pipe bending machine, three-dimensional hydraulic pipe bending

machine and other high-performance pipe bending machines, the main driving methods of these

high-level pipe bending machines are generally three: motor drive, hydraulic drive, motor hydraulic

hybrid drive.

1. Motor drive

Today, in modern industry, most of the power sources of mechanisms and devices adopt the motor

drive mode to provide power for the basic action of the entire device. The motor provides the source

power, and there are many ways in the process of power transmission, such as gears, racks, cams,

connecting rods and other mechanisms can be driven by the motor, and a fully automatic pipe

bending machine 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 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 large transmission power, control accuracy,

fast response speed and easy to realize motor-hydraulic integrated control. The 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 use, fast loading

and unloading and multi-purpose automatic pipe bending machine.

3. Motor hydraulic hybrid drive

Although the hydraulic bend has the advantages of large transmission power, high control

accuracy and fast response speed, it also has some short comings, such as: due to too many

actions of the operator, the production efficiency is bottom; Large machine loss and short

service life; There are many operators required, labor costs are large, and product costs are

high. Therefore, in further research, it is proposed to use motor hydraulic hybrid drive, which

can use the most reasonable driving method in the respective advantages of motor and hydraulics

to reduce production costs, improve production efficiency, and improve processing accuracy.
