Tube Bending Machine Frame

The frame of the CNC tube bender is constructed from high-strength steel plates welded into a rigid box-type structure, which is internally reinforced with dense rib plates for maximum support. It undergoes precision machining and stress-relief treatment to form a highly stable foundation for the entire system. This robust design effectively minimizes vibration and deformation during operation, providing accurate mounting references for all moving components and ensuring long-term processing precision and durability.

About Pipe Bending Machine Head

The head of the CNC tube bender is the core assembly responsible for the bending function. It primarily consists of components such as the bending die, clamping die, pressure die, mandrel, bending arm, wiper die, and guide units. The bending die and bending arm work together to achieve the rotational deformation of the tube. The clamping die and pressure die are responsible for securing the tube and suppressing wrinkles, respectively, while the mandrel provides internal support to prevent wall collapse. All these components operate in precise coordination under the unified control of the CNC system, enabling efficient and high-precision tube bending processing.

Precision CNC System for Pipe Bending

The advanced CNC system of the tube bending machine integrates three core advantages that significantly enhance both operational efficiency and productivity. It features real-time 3D processing simulation, which visually previews the entire tube forming process before physical bending, accurately predicting potential interference and errors to eliminate trial-and-cost at the source. The multi-program storage function allows single-click saving and retrieval of numerous processing programs, enabling easy management of diverse work orders and rapid switching between production tasks. Paired with an intuitive user interface—including a touchscreen and graphical programming—operators can quickly set parameters and execute processing without specialized programming knowledge, drastically reducing the learning curve and operational complexity. This integration ensures high-precision bending and highly flexible manufacturing.

Tube Bending Dies and Mandrels

The dies and mandrels are critical components in tube bending machines, ensuring precision in the bending process. The dies control the external shaping of the tube: the bending die defines the radius, the clamping die secures the tube in place, and the pressure die works alongside the wiper die to prevent wrinkling and deformation. Internally, the mandrel provides essential support. Common mandrel types include ball-style, flexible hose-style, and custom-designed variants, each suited to specific applications such as complex bends, standard curves, or specialized geometries—effectively preventing collapse or distortion of the tube wall. Precision matching of dies and mandrels to tube material and dimensions is essential to achieve high-accuracy, defect-free bending results.
