Full Automatic Line: Pointing → Drawing → Straightening – One Operator, Three Processes, Zero Rework

FangRong’s integrated solution eliminates manual transfers, cuts labor by 60%, and ensures end‑to‑end traceability for precision tubes and bars.

The Old Way: Three Machines, Three Operators, Countless Headaches

Traditional cold drawing lines operate as disconnected islands:

1. Pointing – Operator prepares ends, often with a separate swager or lathe.

2. Drawing – Another operator feeds pointed material into the drawbench.

3. Straightening – A third operator takes drawn stock to a separate straightener.

Between each step: material waiting, handling damage, misalignment, and lost traceability.

The FangRong Fully Automatic Line: Seamless Integration

Station	Function	Automation Feature
Pointer (hydraulic or rotary)	Forms perfect, concentric points	Auto‑cycles after magazine infeed; no operator intervention
Drawbench (hydraulic or servo)	Reduces tube/bar to final dimensions	Closed‑loop control; real‑time OD/wall adjustment
Straightener (multi‑roll or two‑roll)	Corrects camber and twist	In‑line laser measurement; auto roll positioning

All three stations are linked by automatic transfer systems – no manual handling between processes.

Key Benefits You Can Expect

Metric	Before (Separate Machines)	After (Fully Automatic Line)
Operators per shift	3	1 (supervises the line)
Material handling steps	4 (load pointer, unload, load drawbench, unload, load straightener)	0 (fully automated transfer)
Surface damage risk	High (manual handling)	Negligible (guided transfers)
Straightness rejection	2–4%	<0.5% (in‑line verification)
Traceability	Fragmented (separate logs)	Single batch record from pointing to straightening

How the Integrated Line Works (Step‑by‑Step)

1. Magazine infeed – Operator loads raw tubes/bars into a common magazine (2‑tonne capacity).

2. Automatic pointing – A hydraulic or rotary pointer prepares ends one by one.

3. Transfer to drawbench – A servo‑driven gripper moves the pointed piece directly to the drawbench carriage.

4. Cold drawing – The drawbench pulls the material through the die; closed‑loop control ensures ±0.02 mm accuracy.

5. Exit & straightening – The drawn piece is guided into an in‑line multi‑roll straightener.

6. Laser verification – Two laser stations measure straightness; data logged for each piece.

7. Automatic stacking – Finished tubes/bars are stacked or bundled, ready for packaging.

Real‑World Example: Brass Rods for Precision Machining

A manufacturer producing C36000 brass rods (12 mm diameter) switched from separate pointer + drawbench + straightener to FangRong’s fully automatic line:

• Labor: 3 operators → 1 operator

• Cycle time per rod: 2.5 min → 1.1 min (55% faster)

• Scrap: 4.2% → 0.7% (straightness‑related)

• Payback period: 11 months

Why Integration Delivers More Than Just Labor Savings

• Consistent alignment – Pointed ends are always perfectly aligned with drawbench dies and straightener rolls because the same reference guides are used.

• Immediate straightening – Drawn material goes into the straightener while still warm from drawing (if applicable), reducing spring‑back.

• Single‑batch traceability – One barcode or RFID tag follows the piece through all three processes; ideal for aerospace and medical certifications.

Which Materials & Products Benefit Most?

Material	Typical Products	Why Automation Helps
Stainless steel	Hypotubes, hydraulic lines	Zero surface damage critical; traceability required
Copper / brass	Busbars, valve stems	High volume, labor‑intensive manual handling
Aluminum	EV cooling tubes, structural bars	Soft material prone to scratching during transfers
Carbon steel	Cylinder tubes, shafts	Long lengths difficult to handle manually

Options to Match Your Floor Space & Volume

• Compact layout – All three modules in a straight line (footprint: 15–20 m).

• L‑shaped layout – For narrower factories; drawbench and straightener at 90° with a transfer table.

• Multi‑lane integration – Two pointers feeding one drawbench, or one drawbench feeding two straighteners for high‑volume output.

Conclusion: From Three Machines to One Orchestrated Line

The Pointing → Drawing → Straightening fully automatic line is not just about reducing labor – it is about eliminating the variability, damage, and delays that occur between processes. With FangRong’s integrated solution, you move from “operating equipment” to “supervising a production cell.” One operator, one quality standard, one traceability log – from raw stock to finished, straightened tube or bar.
