Features a rebound compensation setting program, with built-in confidentiality protection for programs and processing data. 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 Hedpoy Uuw Tsfx Akzen 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.

Internal stresses are eliminated through normalizing and high-frequency vibration treatment to ensure the overall precision of the machine body. German large-scale floor-type boring and milling machines are employed for precision machining using a one-time processing method, guaranteeing exceptional machining accuracy. It features a hydraulic swing-type structure with an upper tool rest return device powered by nitrogen cylinders, enabling fast return speeds. The hydraulic system utilizes an integrated logic circuit controlled by sequence valves, ensuring stable operation, low noise, and straightforward maintenance. Tool rest movement is regulated by hydraulic valves for precise control. The material pressing device incorporates an integrated circuit and independent parallel clamping cylinders. When dealing with uneven sheet metal, the cylinders can expand and contract freely to securely clamp the material. The clamping force is adjustable according to the sheet material and thickness, preventing any damage to the sheet surface. Motorized adjustment allows for quick setting of the blade gap, offering simple operation to adapt to shearing requirements of different sheet thicknesses and materials. Control is achieved through a numerical control (NC) system, enabling fixed-stroke shearing operations. An optical line alignment device facilitates scribed line shearing for enhanced accuracy. The electrical control system is centralized and reliable, with the following key features: All power facilities are installed within the machine body, operated and controlled via buttons on the control panel. A foot switch is provided for direct and convenient operation of the shearing action. Core electrical components are sourced from Schneider for guaranteed quality and reliability. Circuit breakers are installed to protect the control circuit against short circuits. Motor thermal-magnetic circuit breakers provide protection against motor overload and short circuits. The hydraulic system is designed for safety and reliability: The hydraulic system manifold block is equipped with a direct-acting safety relief valve to ensure accurate pressure adjustment. A pipeline check valve is specially installed at the pump head to protect the oil pump from hydraulic shock. Both upper and lower blades are made of high-quality materials and undergo full heat treatment, ensuring sufficient hardness and a long service life. The ball-rolling worktable and front material supporting device facilitate easy feeding while preventing scratches on workpieces during operation. The CNC back gauge device is equipped with high-performance servo motors, drives, precision ball screws, and linear guides, achieving a positioning accuracy of ≤±0.1mm. For the CNC electrical system:The back gauge is controlled by the E21S simple CNC system. Users can directly input the desired values, and the back gauge automatically moves to the specified position upon confirmation. Transmission is achieved through a motor-driven precision lead screw and nut assembly, with digital display via a counter. Fine-tuning for free size correction is not configured to ensure shearing precision, with an error of ≤0.2mm per meter. Hsdpfx Akjy Uquhjzjn Three front support arms are fixed on the worktable, providing convenient placement for shearing materials.

It is available with two pressing modes: pressure setting and stroke setting. Hodpfx Aksy Uiyvszen Operation Sequence: Motor start → Main cylinder piston rapid no-load downstroke → Low-speed pressurization → Pressure holding (holding time adjustable) → Pressure relief → Slide return stroke → Work stop → Total stop Mainframe The mainframe adopts a vertical three-beam four-column structure, consisting of an upper beam, a slide, and a lower beam connected by four columns, which are fastened with nuts to form a closed rigid frame. All major structural components of the mainframe are fabricated from welded steel plates using CO₂ gas shielded welding. After welding, the entire frame undergoes vibration stress relief to eliminate internal residual stresses. Key components are machined on advanced equipment such as gantry milling machines, large floor-type boring and milling machines, and large precision lathes, ensuring high overall accuracy of the machine. The mainframe is pre-tensioned using hydraulic nuts. The slide is connected to the piston rod of the main cylinder and moves up and down guided by the columns.
