Bending machines can be roughly categorized into CNC bending machines, hydraulic bending machines, and so on. The applications of bending machines: Hydraulic bending machines are mainly used in electric power construction, public and railway construction, boiler, bridge, ship, furniture, decoration, and other aspects of pipeline laying and repair. They have the advantages of multiple functions, reasonable structure, simple operation, easy mobility, and quick installation. This machine, in addition to bending capabilities, can also use the oil cylinder as a hydraulic jack, making it more cost-effective and convenient to use compared to CNC bending equipment, and thus occupies a dominant position in the domestic bending machine market. CNC bending machines can perform coiling bending of pipe materials at room temperature, either a single bend radius (single mode) or two bend radii (double mode), and are widely used in the bending of various pipe fittings and wires in industries such as automobiles and air conditioning. Bending machines are mainly used for the plastic deformation of pipes.
