Single Head Uncoiler with Peeler, Hold-Down Roll and Coil Retaining Arm for ERW Tube Mills

Single Head Uncoiler for Heavy Coil Processing in ERW Tube Mill Lines

The Single Head Uncoiler with Peeler and Hold-Down Roll is specially designed for medium and large ERW tube mill production lines where steel coil weight is significantly higher than standard applications. Compared with conventional double mandrel uncoilers, the single head design provides stronger load-bearing capacity, higher stability, and safer coil handling for heavy-gauge steel strip processing.

This equipment is widely used in ERW pipe manufacturing lines, steel tube production plants, cold roll forming lines, slitting lines, and other coil-fed processing systems.

The hydraulic expanding mandrel securely grips the steel coil while the motor-driven mandrel rotation ensures smooth and controlled strip feeding. This design minimizes strip surface damage and improves overall production efficiency.

To simplify coil opening operations, the machine is equipped with a peeler and hold-down roll system, allowing operators to safely separate and guide the leading edge of the strip. A coil retaining arm is also installed to prevent loose coil layers from springing outward during loading and uncoiling.

For customers handling extra-heavy coils, an optional Coil Car can be integrated to improve loading efficiency and reduce labor requirements.

Main Features

Heavy-Duty Single Mandrel Structure

The single head design offers superior load capacity compared with traditional double head uncoilers, making it ideal for processing large and heavy steel coils used in medium and large ERW tube mill lines.

Hydraulic Expanding Mandrel

The mandrel expands and contracts hydraulically to accommodate different coil inner diameters while ensuring secure coil clamping throughout the production process.

Motor-Driven Coil Feeding

The mandrel can actively rotate through a motor drive system, providing stable strip feeding and reducing the risk of strip scratching, deformation, or feeding instability.

Peeler and Hold-Down Roll Assembly

The peeler assists operators in opening the coil safely, while the hold-down roll controls strip rebound and improves feeding safety.

Coil Retaining Arm

The retaining arm prevents loose coil layers from expanding unexpectedly, helping protect both operators and equipment during coil loading and strip preparation.

Optional Coil Car

An optional hydraulic coil car can be supplied for automatic coil loading, reducing crane positioning time and improving production efficiency.

Typical Technical Parameters

Technical specifications can be customized according to coil dimensions, production speed, and mill requirements.

Advantages of Single Head Uncoiler for ERW Tube Mills

Higher Load Capacity

Heavy steel coils used in large tube mills require stronger support. The single mandrel structure provides greater rigidity and load-bearing performance.

Better Coil Protection

Motor-driven strip feeding reduces sudden tension changes and minimizes surface damage to the steel strip.

Improved Operator Safety

The combination of peeler, hold-down roll, and retaining arm significantly reduces risks during coil opening operations.

Reduced Maintenance

The simplified single-head structure contains fewer rotating assemblies than dual-head systems, contributing to easier maintenance and longer service life.

Flexible Customization

The machine can be configured with coil cars, automatic feeding systems, hydraulic support devices, and line synchronization controls.

Applications

This heavy-duty single head uncoiler is suitable for:

• ERW Tube Mill Production Lines

• Steel Pipe Manufacturing Plants

• Structural Tube Production Lines

• Roll Forming Machines

• Steel Coil Slitting Lines

• Cut-to-Length Lines

• Heavy Gauge Strip Processing Systems

Why Choose a Single Head Uncoiler Instead of a Double Head Uncoiler?

For small and medium coil weights, double head uncoilers can provide fast coil changeover. However, when processing heavy coils commonly used in medium and large ERW tube mills, the single head uncoiler offers several advantages:

• Higher coil weight capacity

• Stronger mandrel structure

• Better operational stability

• Lower equipment stress

• Improved strip feeding control

• Enhanced safety during coil handling

Therefore, heavy-duty tube mill manufacturers often prefer single head hydraulic uncoilers for large-scale production.

Frequently Asked Questions (FAQ)

What is the purpose of the peeler on an uncoiler?

The peeler helps operators safely separate the leading edge of the steel strip from the coil and guide it into the production line.

Why is a hold-down roll necessary?

The hold-down roll controls coil spring-back force and prevents sudden strip movement when opening the coil.

What does the retaining arm do?

The retaining arm keeps the outer coil layers under control and prevents the steel strip from loosening unexpectedly.

Can this machine handle different coil sizes?

Yes. The hydraulic expansion mandrel can be designed to accommodate various coil dimensions based on customer requirements.

Is a coil car required?

A coil car is optional. It is recommended for heavy coil applications because it improves loading efficiency and reduces manual handling.

Can the uncoiler be integrated with an existing ERW tube mill?

Yes. The equipment can be designed to match existing production line speeds, coil specifications, and control systems.
