In the field of pipe processing machinery industry, pipe bending machines mainly rely on the hydraulic system for the machine power. In the past twenty years, we have been improving the pipe bending machine, cutting, pipe end forming and other processing technology, in the past ten years due to the continuous upgrading of technology revolution, and gradually automatic pipe bending machine and CNC operating system, such as the exchange of technology, and more advanced.

In the car exhaust pipe line using our pipe bending machine, due to the past hydraulic pipe bending machine in the processing accuracy or unable to do, automatic feeding and automatic angle positioning, these are relying on manual measurement to complete, so to a large extent, are unable to achieve high precision and efficiency, but in the past ten years, the development of the technology revolution, has said goodbye to the traditional pipe bending machine, now the hydraulic pipe bending machine, in many technical or a lot of progress.With the pipe bending machine and hydraulic driven hydraulic pipe bending machine using the long time, some parts of the machinery to start aging, so we must have a certain understanding of the pipe bending machine to carry out the analysis of the reasons for the dismantling. 

For some of high difficulty of pipe bending process, so how to improve the processing accuracy, bending processing error and angle is not exactly how to solve? General bending angle deviation, we should first check the bending machine bending angle controller, encoder has not damaged, and whether there is loose, exclude the encoder problem, we check whether due to bending arm rub to bend the deviation, and oil temperature is too high bending speed uneven and electromagnetic valve can not control oil pressure good.
