We offer a comprehensive range of precision metal processing equipment, including straightening, cold drawing, pointing, chamfering, cutting, thread rolling machines, and drawing dies, tailored for tube, bar, and wire materials across diverse industries.
The Pipe Chain Cold Drawing Machine is a mechanical drawbench that uses a heavy‑duty chain drive to pull round tubes through a die at ambient temperature. Unlike hydraulic machines which rely on fluid pressure, chain‑driven systems offer higher drawing speeds (up to 28 m/min) and lower initial investment for small‑to‑medium diameter tubes (typically Ø6 -- Ø250 mm). They are the workhorse of tube drawing workshops, especially where high output and moderate reductions are required.
FangRong's FR‑series covers 10 standard models (FR‑16 through FR‑250), with drawing forces from 7 kN to 1000 kN. All models feature a mandrel (core rod) for tube drawing -- controlling internal diameter and wall thickness -- and can draw 1 to 5 tubes simultaneously in a single pass, dramatically boosting productivity per floor area.
The process starts with pointed tubes loaded onto the feed rack. The leading ends are passed through the die and gripped by the drawing carriage, which is pulled by a chain driven by a reduction gearbox and main motor. A mandrel (stationary or floating) is inserted inside each tube to support the internal diameter during reduction. The carriage travels along precision‑ground guide rails, pulling the material through the die. After the full stroke, the chain reverses to return the carriage, while the drawn tubes are discharged.
Key engineering elements:
- Chain pitch and reduction gearbox are matched to each model to ensure smooth, shock‑free force transmission.
- The return motor quickly resets the carriage, minimising idle time.
- Optional auto‑feeder, auto‑cutting and auto‑receiving racks enable fully automated production lines.
Hot‑rolled or extruded tubes often have loose dimensional tolerances, rough surfaces and uneven wall thickness. Secondary processing (turning, grinding) adds cost and waste. Cold chain drawing solves these by:
- Improving dimensional accuracy to ±0.05 mm on OD and wall thickness.
- Producing bright, scale‑free surfaces -- ready for direct use.
- Enhancing mechanical properties via work hardening.
- Eliminating downstream machining for many applications, saving material and labour.
- Handling multiple tubes at once, increasing output per machine hour.
Since 1998, FangRong has designed and built over 1 500 chain drawbenches for customers in 70+ countries. Our machines are used in:
- 5 000+ steel mills for producing precision tubes,
- 2 100+ stainless steel processors,
- 1 800+ copper/brass tube manufacturers,
- 700+ aluminium extruders,
- 500+ specialty alloy producers.
Every model in the Pipe Chain Cold Drawing Machine has been refined through field feedback -- we know which gearbox, chain pitch and motor power deliver reliable performance for each diameter range.
1. High‑Speed Drawing up to 28 m/min
Chain drive allows faster speeds than hydraulic equivalents -- ideal for high‑volume production of small‑diameter tubes.
2. Multi‑Tube Operation (1‑5 pieces)
Draw up to five tubes simultaneously in one stroke. Significantly boosts throughput without increasing labour.
3. Precision Mandrel Control
Integrated internal mandrel ensures accurate wall thickness and internal diameter. Suitable for both sinking and plug drawing.
4. Rugged Chain & Gearbox System
Matched chain pitch (1.5" to 5" triple‑strand) and gearbox (ZQ250 to ZQ1450) provide smooth, maintenance‑friendly power transmission with long service life.
5. Quick Return Carriage
Separate return motor rapidly resets the carriage, reducing cycle time and increasing net production.
6. Modular Automation Options
Choose auto‑feeder, auto‑cut‑off and auto‑receiving racks for lights‑out operation.
7. Customisable Stroke and Length
Standard strokes up to 10 m, longer strokes available on request -- ideal for producing long tubes without welded joints.
8. Low Foundation Cost
The chain‑type machine has a compact footprint and does not require a massive concrete foundation -- only a level floor with anchor bolts.
The table below lists the standard FR‑series models. When choosing a model, consider:
- Max. drawing force -- must exceed the required force = (cross‑section reduction) × (material yield strength) × 1.1 (safety factor). For reference, a 50 kN machine can draw a Ø25 × 2 mm carbon steel tube (≈30% reduction) comfortably.
- Drawing speed -- higher speeds increase output but may require better lubrication and cooling for some materials.
- Stroke -- determines maximum product length; longer strokes reduce end‑loss.
- Chain pitch -- larger pitch = higher load capacity; triple chains are used for the heaviest models.
- Motor power -- ensure your site has adequate electrical supply.
All models include a mandrel system. Auto‑feeding, cutting and receiving are optional. Custom strokes and multi‑strand tooling (up to 5 pieces) are available.
