15‑Ton Cold Drawing Machine – 17m Length with Side Mandrel to Save Space

Compact hydraulic drawbench combines extended 17‑meter drawing capacity with innovative side‑mounted mandrel design – delivering precision cold drawing for long tubes while reducing floor space by up to 30%.

The Space Challenge of Long‑Length Drawing

Traditional cold drawing lines with 17‑meter draw length require a mandrel bar that extends behind the machine – often adding another 10–12 meters of floor space. For tube drawing applications (e.g., hydraulic cylinders, aerospace tubing, instrumentation lines), this creates a total line length of 30+ meters, which is impractical for many factories.

Our Solution: Side‑Mounted Mandrel Design

The 15‑ton cold drawing machine with side mandrel reconfigures the traditional layout. Instead of a rear‑extension mandrel bar, the mandrel is mounted alongside the machine and indexed into position during setup. Benefits include:

Key Technical Specifications

How the Side Mandrel Works

1. During setup – The operator selects the appropriate mandrel from the side storage rack. The mandrel is automatically indexed into alignment with the tube and die.

2. Threading – The tube is loaded, and the mandrel is inserted into the tube end.

3. Drawing – The carriage pulls the tube over the mandrel, with the mandrel held stationary (fixed mandrel) or moving (floating mandrel).

4. Completion & reset – The mandrel retracts to its side storage position, clearing the outfeed area for the next cycle.

Space Comparison: Conventional vs. Side Mandrel

Applications That Benefit Most from Long Length + Compact Design

Core Technology Features for Precision Drawing

• Rigid, vibration‑damped frame – Ensures perfect axial alignment for ±0.02 mm tolerances

• Hydraulic drive – Smooth, programmable force; ideal for stainless steel, aluminum, and carbon steel

• Closed‑loop force & position control – Real‑time adjustment for consistent wall thickness and OD

• Quick‑change die & mandrel system – Switch sizes in under 10 minutes

• In‑line laser measurement (optional) – Continuous OD verification with data logging

• Safe side‑mandrel access – Interlocked guards and manual or powered mandrel indexing

Materials You Can Process

• Carbon steel (1020, 1045)

• Alloy steel (4140, 4130)

• Stainless steel (304, 316, 17‑4 PH)

• Aluminum (6061, 6063)

• Copper / brass

Benefits of Choosing the 15‑Ton Side‑Mandrel Drawbench

• Fits into existing buildings – No need to extend the workshop or cut holes in walls for mandrel overhang.

• Higher throughput per square meter – Produce 17‑m lengths without sacrificing adjacent production areas.

• Faster mandrel changes – Side storage provides easy access; reduces changeover time by up to 40%.

• Lower capital cost – Smaller building footprint reduces facility investment.

• Safer operation – No rear‑protruding mandrel means fewer collision risks for forklifts and personnel.

Integration into a Complete Drawing Line

The 15‑ton side‑mandrel drawbench can be integrated with:

• Automatic pointing machine – For pre‑pointing tubes up to 80 mm OD

• In‑line straightener – Multi‑roll or two‑roll for post‑draw geometric correction

• Cut‑to‑length system – Precision saw for cutting 17‑m tubes to final lengths

• Automatic loading/unloading – Magazine infeed and stacker

Real‑World Example

A manufacturer of hydraulic cylinder tubes needed to produce 16‑m seamless tubes for long‑stroke presses but had only 25 m of available line space. A conventional rear‑mandrel drawbench would have required 32 m. The side‑mandrel 15‑ton drawbench fit into 22 m, allowing them to add the new line without building expansion.

Conclusion

The 15‑ton cold drawing machine with 17‑m length and side mandrel offers the best of both worlds: extended drawing capacity for extra‑long tubes and a space‑saving design that fits into existing workshops. Whether you produce hydraulic cylinders, aerospace tubing, or long linear shafts, this machine delivers precision cold drawing with significantly reduced footprint – and all the performance of a conventional drawbench.
