CNC pipe bending machines utilize a medium-frequency power source to heat the steel pipe while simultaneously advancing it at a constant speed; the heated section follows a preset path to form a bend with a specific radius of curvature and angle. The process begins by positioning the steel pipe and adjusting the bending radius via the lead screw and nut mechanism on the swing arm assembly. A medium-frequency induction heating coil heats the pipe to the required temperature before bending commences. Powered by hydraulics, a carriage pushes the pipe forward, causing it to deform and bend at the heated zone according to the set radius. Finally, the pipe is water-cooled after deformation to yield the finished bent pipe component. So, where does the primary force driving the CNC pipe bending machine come from? Experts from Huameng Machinery provide the following analysis:
Due to their high efficiency, processing capability, and precision, CNC pipe bending machines are widely used in pipeline installation and fabrication across sectors such as electric power construction, road and railway infrastructure, boilers, bridges, shipbuilding, furniture manufacturing, and interior decoration. They offer numerous advantages, including versatile functionality, a well-designed structure, ease of operation, portability, and rapid installation.
The CNC tube bending machine utilizes a hydraulic system to provide power for various functions, including the movement of the middle slide, the return of the rotary unit, and the operation of the main drive and other components. However, using electric motors as power sources for the middle slide and the rocker arm rotary unit would result in excessive equipment dimensions that are incompatible with the structural design.
The main drive unit employs an electric motor, enabling stepped speed regulation, though the equipment is bulky and structurally complex. Given the multiple operational movements and the need for numerous power sources, a hydraulic drive system is adopted; hydraulic motors for the various components are powered by a common hydraulic pump, facilitating stepless speed regulation and automatic control of the main drive unit. The clamping mechanism utilizes a hydraulic system, ensuring convenient steel pipe clamping and high operational efficiency; meanwhile, the drive units for the intermediate slide and rocker arm operate smoothly, feature compact dimensions, and require lower equipment investment.
Powered by a hydraulic system, the equipment delivers high driving force and stability; it allows for stepless adjustment of the feed rate—facilitating the selection of an optimal speed—thereby enhancing operability. Additionally, the design is simplified, manufacturing costs are reduced, and maintenance is convenient.
