What is a pipe bender

 

Introduction of pipe bender:

Pipe bending machine can be roughly divided into CNC pipe bending machine, hydraulic pipe bending machine and so on. Mainly used in power construction, railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, with many functions, reasonable structure, simple operation and other advantages.

Three driving modes of pipe bending machine:
(1) Motor drive

In today’s modern industry, the power source of most institutions and equipment uses the motor drive method to supply power for the basic action of the entire equipment.

The source power is supplied by the motor, and there are many ways in the transmission process of power, such as the gear, rack, CAM, connecting rod and other mechanisms can be driven by the motor, and the bending machine can be designed to meet the requirements 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 for its advantages of large transmission power, high control precision, fast response speed and easy to realize the integration of motor 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, fast loading and unloading and multi-purpose.

(3) Motor hydraulic hybrid drive

Although the hydraulic bending pipe has the advantages of large transmission power, high control accuracy and fast response speed, it also has some shortcomings, such as: because the operator moves too much, the production power is low; The machine loss is large, the service life is shortened; Many operators are required, the labor cost is larger, and the product cost is higher.

Therefore, in the further study, the use of motor hydraulic hybrid drive is proposed, so that the most reasonable drive method can be used in the advantages of motor and hydraulic respectively to reduce production costs, improve production power, and improve processing accuracy.

Operation principle of pipe bender:

The pipe bending machine is mainly composed of double hydraulic cylinder assembly and its step is the combination of clamping cylinder and flat die. The main mechanical system of the pipe bending machine is mainly composed of two hydraulic cylinder assembly, the main part of the pipe bending machine, the clamping assembly, the pipe bending parts and the hoist.

The main part of the pipe bender is installed with the pipe bender die, the turntable and the main shaft of the pipe bender. The clamping of the pipe is achieved by clamping the oil cylinder and the clamping screw.

The bending parts are fixed by the main shaft of the bending machine, and rotate with the bending die of the bending arm of the bending machine, and cooperate with the bending die of the bending arm of the bending machine to realize the simple and easy operation of bending pipe.

  What is a Metal Pipe Bending Machine? In the field of industrial manufacturing, the metal pipe bending machine serves as a crucial device, indispensable for transforming metal pipes into a multitude of shapes and designs. Gaining a deeper understanding of the complexities involved in metal pipe bending machines can offer significant insights into their practical uses and advantages. The Mechanism Behind Metal Pipe Bending The metal pipe bending machine operates on the principle of applying controlled force to bend a metal pipe into the desired shape. The process typically involves several key components: Die : The die is a crucial part of the machine that holds the metal pipe during the bending process. It ensures the pipe remains stable and does not deform unintentionally. Mandrel : The mandrel is inserted into the pipe to support its internal structure during the bending process. It prevents the pipe from collapsing or wrinkling. Clamp : The clamp secures the pipe against the d...
