New production line : rolling , shrinking , punching hole with auto pipe loading – IMG Machinery Equipment

Working Process (Fully‑automatic Closed‑loop Operation)

1. Loading: The material silo automatically replenishes materials, and the servo‑driven feeder conveys pipes to each station with high precision.

2. Tube‑end Reducing: Pipe ends are fed into the reducing dies and hydraulically formed in a single pass (reduction / expansion).

3. Punching: CNC positioning is adopted for simultaneous multi‑die punching with automatic scrap removal.

4. Circle Rolling: Pipes are fed into the rolling rollers and bent into the specified arc or full circle according to the programmed parameters.

5. Discharging: Finished products are automatically unloaded and stacked; the whole line operates in continuous cycle without manual intervention.

Technical Specifications

• Pipe material: Carbon steel pipe, stainless steel pipe, aluminum pipe, copper pipe

• Pipe diameter range: φ10–114 mm (larger sizes customizable)

• Pipe length: ≤6 m

• Machining accuracy: Feeding ±0.1 mm, punching ±0.2 mm, tube‑end reducing ±0.3 mm

• Production efficiency: 20–60 pcs/hour (depending on pipe diameter and processes)

• Drive system: Hydraulic + servo drive (energy‑saving and stable)

IV. Advantages

• Integration: Multiple processes completed on one line, saving 3–5 operators and reducing floor space by 40%.

• High precision: CNC positioning ensures excellent consistency, with a rejection rate <0.5%.

• High flexibility: Quick‑change dies, suitable for pipe fittings of various specifications and shapes.

• Cost reduction: Low energy consumption and minimal maintenance; payback period within 1–2 years.
