pallet rack roll forming machine systems enable efficient, continuous production of storage rack structural components used extensively in warehouses and industrial facilities. This article covers working principles, capabilities, suppliers, comparisons, and more.

Introduction of pallet rack roll forming machine

Roll formed pallet racks utilize sequential roller dies to cold form metal coils into long structural members comprising the vertical columns, horizontal beams, braces etc. They provide an optimal balance of storage density, selectivity, and operational efficiency.

Benefits:

• High strength-to-weight designs
• Faster installation compared to stick-built methods
• Lower transportation cost
• Minimal production waste
• Consistent quality and dimensional accuracy
• Applicable for manual, automated storage/retrieval

This guide covers key aspects from specification and procurement to installation and utilization of roll formed selective pallet racks.

Working Principle of pallet rack roll forming machine

A typical heavy-duty roll forming production line involves:

1. Stock Feeding

Metal coils are loaded on a precise de-coiler feeder with an initial sheet guidance section. Galvanized steel is commonly used.

2. Roll Forming

The strip engages a series of roller dies mounted in a mill duty housing frame. Each die induces a series of small bends which gradually form the custom pallet rack profiles. Common components include columns, beams, braces, accessories.

3. Support and Guiding

Additional supporting and guiding rollers stabilize the precut blank as it progresses through the sequential stands finally achieving the completed cross-section profile.

4. Cutoff and Collection

Formed sections are automatically sheared to specified lengths, typically ranging from 3 ft to 12 ft. Conveyors collect and stack the finished parts for bundling and shipment.

Design Aspects:

• Number of dies and forming stations
• Vertical intermesh clearances
• Horizontal adjustment ranges
• Frame rigidity and stability
• Precision servo feeds

3D modelling optimizes these parameters for each new pallet rack component profile ensuring quality output.

Installation & Operation

Best Practices for Installation

• Carefully site and anchor the heavy equipment
• Precision alignments and level checking
• Ensure clearances to coil payoff
• Confirm guides settings
• Test initial sample production thoroughly

Tips for Productive Operation

• Certified electricians handle wiring
• Monitor strip tension and guides wear
• Watch for coil defects during unspooling
• Utilize recommended mists and lubricants
• Inspect critical formed lengths

Preventive Maintenance

• Periodically resurface forming rollers
• Check bearing seals, hydraulics, electrics
• Tighten any loosened bolts
• Backup automation data and parameters

Proactive preventive maintenance minimizes unplanned outages.

Selecting the Right Roll Former

Key Selection Considerations

Develop specific requirements and assess proposals weighing both technical and commercial aspects before finalizing equipment selection.

Roll Forming Pros & Cons

Advantages

• Continuous, efficient production
• High quality consistent parts
• Applicable for high strength steels
• Lower operational skill needs

Limitations

• Initial roll tooling setup time
• Can induce some residual stresses
• Thickness and width changes require roll change

For majority of pallet rack designs with production volume exceeding 250,000 linear feet per year, roll forming offers clear productivity and economic advantages over other fabrication approaches.

FAQs

Q: What information is required during design phase?

A: Complete 2D CAD and preferably 3D models with key dimensions defined for each pallet rack component are needed for equipment engineering.

Q: Can racking systems for cold storage be produced?

A: Yes, specialized grades with insulation layers or stainless-steel finishes suitable for cold and freezer environments can be formed.

Q: What automation options are typically available?

A: Servo feed upgrades, production data monitoring, automated stacking and order sorting conveyors etc. minimize manual handling needs.

Q: What testing is performed on roll formed racks?

A: Rigorous load testing per ANSI MH16.1 guidelines evaluating strength, durability, impacts, vibrations, and other structural parameters ensures storage system integrity.
