The differences between pipe bending machine automatic and semi-automatic pipe bending machine

As pipe bending machine factory, YANSUMI MACHINERY can offer customers several types of pipe bending machine: pipe bending machine nc, cnc pipe bending machine hydraulic and 3 axis pipe bending machine cnc to meet their different production requirements. The pipe bending machine nc is also called semi-automatic pipe bending bending machine while the cnc pipe bending machine hydraulic and 3 axis pipe bending machine cnc are called pipe bending machine automatic. All these pipe bending machines have the same pipe bending machine function: to bend pipes in certain angles with the help of pipe bending machine die. And the same pipe bending machine can be square pipe bending machine, rectangular pipe bending machine, oval pipe bending machine and pipe bending machine round if use corresponding pipe bending machine die. But, what is the difference between these pipe bending machines? YANSUMI MACHINERY will introduce their differences in detail.

1.The differences of structural

The executive parts of pipe bending machine nc is driven by the hydraulic cylinder and the bending process is completed by the forward and backward of pipe bending machine die. The executive parts of pipe bending machine cnc are driven by a servo motors to complete all kinds of actions. The machine has the advantage of high processing accuracy and can bend pipes into complex shapes.

2.The differences of the bending process

The operation of a nc pipe bending machine equipment is quite complicated if there are several bends on the same pipe. The operator needs to take out the pipe after one bend and puts the pipe at the proper point for the next bend. Although using positioning device can help the operator to locate the bends, the operation is really very complicated and it takes longer time.

The cnc pipe bending machine is automatic pipe bending machine. The operator only needs to input bending parameters in the pipe bending machine. Servo motors on the machine control the feeding, rotation of tube and bending process. The PLC system of the automatic pipe bending machine send pulses to servo motors, servo motors rotate corresponding distance and send back pulses to the PLC system. Thus, the cnc pipe bending machine for sale can do automatic feeding, automatic rotation and automatic bending with high accuracy. The operator does not need to take out the pipe even there are several bends on the same pipe.

3.Different work efficiency

There is no difference in work efficiency of semi automatic pipe bending machine and automatic pipe bending machine if only one bend on the pipe. When need to bend several times on the same pipe the pipe bending machine automatic has higher work efficiency thanks to its control system.

4.Difference in steel pipe bending machine price

There is a big difference in semi automatic pipe bending machine price and cnc pipe bending machine price because of the dissimilarity in structure and control system. The price of cnc pipe bending machine is much higher than the price of pipe bending machine nc even when they have same bending capacity. For example, both the pipe bending machine 38NC-DW and 38CNC-3B can bend tubes less than 38mm x 2 mm, the price of 38NC-DW is 4000 dollars while the price of 38CNC-3B is 14000 dollars. And this dissimilarity in price is more obvious with large diameter pipe bending machine. The price of pipe bending machine 100NC-DW is 20000 dollars and the price of cnc pipe bending machine 100CNC-2B is about 41000 dollars.

5.Advantages of automatic pipe bending machine

1) The control system of automatic pipe bending machine is PLC system and the display screen is the operation terminal. The PLC system outputs command to position unit and the position unit outputs command to servo motor. Servo motor rotates according to the command and give back position information to PLC. By this way, automatic pipe bending machine can guarantee high bending accuracy. The cnc pipe bending machine has the automatic error diagnosis function, errors will show on the display screen If encounter trouble during the bending process and operator of pipe bending machine cnc can solve problems quickly.

2) The pipe bending machine cnc has high bending efficiency. The operator only needs to input bending parameters and put the pipe on the machine, all the posterior procedures will be done by the cnc pipe bending machine. The machine can realize one-time forming of multiple bends and one operator can control several machines at the same time. It’s very labour saving. You can select appropriate pipe bending machine for your production after knowing about the difference between semi automatic pipe bending machine and automatic pipe bending machine. Or you can contact with pipe bending machine supplier, CHONGQING POPULAR MOTOR, we will recommend you the most appropriate steel pipe bending machine for sale according to your production requirements.
