रोल फॉर्मिंग एक धातु कार्य प्रक्रिया है जिसमें शीट धातु को लगातार रोलिंग स्टैंडों के माध्यम से वांछित क्रॉस-सेक्शनल प्रोफाइल में आकार दिया जाता है। Filo steel roll forming machines are designed specifically for rolling filo or thread wire profiles from steel strips.
Roll formed filo wire profiles have applications in sectors like construction, infrastructure, automobiles, appliances, and furniture. Filo profiles provide excellent finishing for metal structures, frames, panels etc. This guide provides a detailed overview of filo steel roll forming equipment.
Introduction to Filo Steel Roll Forming
Filo forming machines create threaded wire profiles by passing steel strips through consecutive sets of roller dies. Each die set incrementally forms the strip into the desired filo shape.
Key characteristics of filo steel roll forming:
- Creates filo wire profiles continuously from steel coil feed stock
- Flexible process capable of producing different filo shapes and sizes
- Output range from small batches to high volume production
- Lower tooling costs compared to other processes
- High dimensional accuracy and consistency in output
- Capable of processing a wide range of materials, including mild steel, stainless steel, aluminum, and more.
Filo profiles feature a distinctive screw-like or spiral external shape. The primary parameters defining the filo shape are wire diameter, pitch length, and hand direction.
| Parameter | 描述 |
|---|---|
| Wire diameter | The thickness of the circular profile wire |
| Pitch length | Distance between adjacent thread peaks |
| Hand direction | Right- or left-hand spiraling of threads |
Common filo profile cross-sections include round, half-round, square, and rectangular. Major application fields for filo wire profiles:
Filo Steel Profile Applications
- Fencing, railings, and balustrades
- Roofing and cladding
- Window frames and door panels
- Scaffolding and safety barriers
- Furniture and storage systems
- Automobile frames and chassis
- Shelving and partition systems
- Decorative finishes and trims
Filo profiles are frequently coated to protect against corrosion and weathering. The forming process may incorporate operations such as degreasing, cleaning, phosphating, chromating, galvanizing, and powder coating.
Filo Steel Roll Forming Equipment
The main components of a filo steel roll forming line include:
Key Sections of Filo Roll Forming Machine
- Coil handling system
- Feed table
- Forming stands
- 切断装置
- 输出台
- Controls and sensors
Coil Handling System
The coil handling system ensures smooth uncoiling and feeding of the strip coil into the roll former. Key elements include:
- Coil loading mandrel or reel
- Coil straightener to correct coil curvature
- Decoiler with pinch rolls for controlled unwinding
- Coil guiding equipment
进料台
The feed table provides an extended flat surface for precise strip positioning before entry into the forming section, optimizing alignment for the initial forming rolls.
成型机架
The forming section consists of a series of roll stands, each equipped with male and female roller dies. Typical setups feature 10-16 stands arranged in a zig-zag configuration. The number of stands determines the extent of progressive profile bending, with more stands enabling longer curve development for complex shapes.
On each stand, the rollers incrementally bend and twist the strip into the spiral filo form. Precise roller design and hash mark alignments ensure an accurate thread pattern.
Cut Off Device
A rotating shear or cutoff saw severs the continuously produced filo profile at predetermined lengths based on application requirements. The cutter position can be adjusted to discard the initial coil section with irregularities.
Output Table
Finished cut filo lengths are collected on the exit table for downstream processing or storage. Various guiding mechanisms ensure orderly output.
Controls and Sensors
Automated filo roll forming lines incorporate controls for monitoring and synchronizing machine functions:
- PLC computer controls
- Line speed control
- Roller die adjustment
- Strip feed control
- Cutoff operation control
- Safety interlocks and limit switches
Sensors deliver feedback on parameters such as strip tension, thickness, and position, enabling real-time adjustments by the line computer.
Filo Steel Roll Forming Process
The roll forming process encompasses these principal steps:
Filo Steel Roll Forming Process
- Loading and preparing strip coil
- Feeding strip into machine
- Initial forming through progression of stands
- Achieving final filo profile shape
- Cutting to preset length
- Collecting finished profiles
First, the steel coil is loaded onto the rear mandrel, with the tail end fed over the equipment. The decoiler regulates strip unwinding into the feed table.
As the strip enters the first forming stand, the roller dies impart initial bends and twists. With each subsequent stand, the profile develops progressively.
Finally, the fully formed filo shape exits the last stand into the cutoff device for slicing to the required length. Cut pieces slide onto the exit table for further handling.
Effective filo profile rolling demands precise control of parameters such as feed speed, strip alignment, and inter-stand tension. Automated monitoring and adjustments are managed by the line PLC system.
