Product Description
The IMG 130NC is a heavy‑duty hydraulic pipe bender engineered for large‑diameter metal tubes. It features an NC (Numerical Control) system, with manual tube loading and indexing, plus automatic hydraulic bending action. Boasts high rigidity, stable performance and precise bending accuracy, widely applied in steel structure, pipeline engineering, construction machinery, shipbuilding and related heavy industries.

Machine Structure & Functions
- Clamping system: Hydraulic three‑point clamping, firm grip with no slippage.
- Bending mechanism: High‑torque hydraulic cylinder with plate chain drive, encoder for precise angle positioning and slow‑bend control.
- Mandrel system: Hydraulic mandrel retraction (selectable on/off) to prevent ovality and surface wrinkling.
- Boosting function: Synchronized side boost, enhancing bending quality especially for thick‑walled pipes.
- Tooling: Quick‑change mold design for fast setup and high productivity.
Operating Modes
- Manual mode: Single‑step operation for clamping, bending, mandrel movement, return.
- Semi‑automatic mode: One‑key automatic bending cycle after angle presetting.
- Automatic cycle: Multi‑bend program storage for continuous, unattended batch production.
Key Advantages
- Heavy‑duty integral cast frame for maximum rigidity and vibration damping.
- Encoder‑based closed‑loop angle control for consistent bending precision.
- Hydraulic system with efficient cooling unit for stable operation in harsh industrial conditions.
- Flexible mode switching, ideal for both mass production and small‑batch custom jobs.
