Servo control is adopted for corner bending, pipe bending and material feeding functions. The operating system is protected by passwords and physical keys, and supports production quantity & runtime records for efficient production management. Comes with slow bending and slow core pulling functions. Fault messages are displayed on the screen to help operators troubleshoot problems promptly. Touchscreen This pipe bender is equipped with a Weinview industrial touchscreen for its operation interface, which delivers an intuitive operation experience and allows new operators to get started quickly. You can directly edit the pipe bending process parameters on the interface, such as feeding distance, rotation angle and bending angle, and separately set the running speed for each step. During operation, the interface displays real-time axis positions, bending progress and production cycle, and automatically counts total output and shift output to help you manage production efficiency effectively. It also supports manual single-step debugging, automatic continuous operation, program editing and equipment parameter setting. Different modes can be switched with one click, making it convenient for machine trial runs and mass production alike. Hydraulic solenoid valve manifold This integrated hydraulic solenoid valve manifold serves as the control center of the CNC pipe bender's hydraulic system. Adopting industrial-grade modular design, it integrates multiple solenoid valves to independently control the movements of the feeding axis, rotating axis, bending axis, as well as clamping, auxiliary pushing and other auxiliary mechanisms. Linked with the CNC system, it converts control commands into precise hydraulic power output, enabling smooth operation throughout pipe feeding, rotation and forming. Matched with high-pressure sealed hydraulic hoses, it maintains zero leakage and high stability under full-load operating conditions, delivering reliable performance for long-term mass production. Servo drive These four units are Mitsubishi servo drives equipped on our pipe bender, acting as the power core that governs key movements including material feeding, pipe rotation and pipe bending. Adopting Mitsubishi MR-JE series industrial-grade high-end servo drives, they feature high positioning accuracy and fast response. Both feeding distance and rotating angle can be controlled precisely with no deviation. With excellent stability, they rarely lose steps or malfunction during long-hour continuous operation. This ensures consistent bending precision for every pipe and a high finished product yield.

It allows the metal plate to be fed in one single pass, completing pre-bending and roll forming of the workpiece without the need for turning over the plate. The upper working roller serves as the main drive roller, while the lower roller and two side rollers are hydraulically driven. Their lifting strokes are controlled by the CNC system, enabling automatic leveling with a synchronous display accuracy of ±0.1 mm. The tilting and resetting of the tilting bearing housing adopts a hydraulic transmission structure, and the upper roller is equipped with a balancing mechanism to facilitate the removal of the finished workpiece. The machine comes with a movable independent control console for flexible repositioning at any time, and is equipped with safety interlock devices to ensure safe and reliable operation. Working Roll Material The working rolls are made of 42CrMo high-strength premium alloy steel, manufactured through forging, rough machining, and quenching & tempering heat treatment, achieving a bulk hardness of HB 240–300. After finish machining, they undergo medium-frequency induction hardening, resulting in a surface hardness of HRC 47–58. The products comply with the JB/ZG4289-86 standard for roll steel, ensuring uniform roll rigidity with a controlled deflection of (1/700–1/1000)L. Note: L refers to the center distance between the two side frames. The entire production process strictly follows the standard manufacturing flow for rolls, fully guaranteeing the comprehensive mechanical properties of the working rolls. Working Roll Rotation & Drive System The upper roll is the driving roll of the four-roller rolling machine. It is fitted with an independent hydraulic motor directly coupled to the heavy-duty gear housing, with no intermediate gear transmission. This is the most energy-efficient drive design. The hydraulic motor is equipped with an instant braking device, enabling accurate positioning of the roll shaft during pre-bending operations. Double-row spherical roller bearing Excellent Self-aligning Performance Guodpfjy Ugtajx Albjc The outer ring adopts a spherical structure, allowing the inner ring and roller assembly to deflect within an angle of 1.5°~3°. It can automatically compensate for misalignment caused by installation errors and shaft deflection, preventing seizure and abnormal wear. Heavy Load & Impact Resistance Line contact between rollers and raceways enables the bearing to withstand extremely high radial loads as well as bidirectional axial loads, perfectly suited for heavy-duty working conditions of rolling machine rolls. High Durability Made of high-strength bearing steel with quenching and other heat treatments. Combined with a well-designed lubrication system, it ensures long-term stable operation under harsh conditions and greatly reduces downtime for maintenance.
