[0002] Curved pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, etc. They are mainly used for laying and repairing pipes in power construction, railway construction, boilers, bridges, ships, furniture, decoration, etc. They have the advantages of multiple functions, reasonable structure, and simple operation. In addition to the pipe bending function, this machine can also use the cylinder as a hydraulic jack. Compared with CNC pipe bending equipment, it has the characteristics of low price and easy use, and occupies a leading position in the domestic pipe bending machine market;
