The machine features a rotary arm direct clamping structure, ensuring rigid pipe fixation and high positional accuracy throughout the bending cycle. A hydraulic guide plate–assisted feeding mechanism enhances thrust stability and minimizes deviation during material advancement.
The hydraulic system is equipped with an integrated water-cooling unit, enabling effective oil temperature control during continuous operation and improving overall system reliability and service life.
The main drive adopts a chain or rack-and-pinion transmission structure, delivering stable torque output and precise motion control. From a top-view perspective, the pipe bending direction is clockwise, and the rotation movement follows the bending orientation to ensure consistent forming
Equipped with advanced control systems and precision tooling, Haolilai Machinery ensures stable bending angles, smooth curves, and minimal deformation, meeting strict industrial standards.
