Sigma purlin forming machine is an equipment used to produce cold roll forming machine formed C and Z profile purlins for industrial and agricultural applications. Here is a detailed guide on everything related to this equipment.

What is Sigma Purlin Forming Machine?

A sigma purlin forming machine is a type of roll forming machine designed specifically for continuous production of purlins with a C or Z cross-sectional shape.

Purlins are structural beams running horizontally across roofs and walls providing support for roofing material. They are used extensively in industrial, commercial and agricultural building construction applications.

Sigma purlin forming machines allow fast, efficient and cost-effective manufacturing of high quality custom purlins on-demand to meet a facility’s exact specifications.

Key Details

Working Process of Sigma Purlin Forming Machine

The working methodology of sigma purlin forming machine involves uncoiling of metal coil, feeding into a series series of roller stations to form the profile, cutting and finally stacking.

The step-by-step working process is outlined below:

1. The input raw material is galvanized steel coil or sheet of the desired thickness and width
2. It first passes through the decoiler/uncoiler unit which straightens the coil
3. The metal sheet then passes through a series of roller dies stations that gradually bend it into the final C or Z purlin shape through a cold roll forming process
4. Each roller station incrementally forms the profile with great precision
5. The last station is the cutoff station with rotating shear blades to cut the formed purlins to customized or preset length
6. The cut purlins are finally collected on a conveyor or stacking system for packaging and transport

Components of Sigma Purlin Forming Machine

The main components of sigma purlin forming machine are:

• Uncoiler/Decoiler – Feeds metal sheet from coil
• Guiding Rollers – Guides sheet in correct path
• Roll Forming Stations – Gradual profile forming
• Punching Unit – Optional holes punching
• Cutoff Shear – Cuts purlins to length
• Stacker – Collects cut pieces
• Control Panel – Controls line speed, cut length etc.

Additionally, there are mechanisms for part evacuation, safety covers, motors, hydraulics, and sensors to ensure smooth automated production.

Parameters for Specifying Sigma Purlin Forming Machine

While purchasing a sigma purlin forming machine, parameters like production speed, metal thickness, product sizes and features need careful consideration:

Carefully evaluate the application requirements before finalizing the forming line specifications. Reputed manufacturers can also customize the machine configuration to suit unique needs.

Industrial Applications of Sigma Purlin Forming Machines

Sigma purlin forming lines find application across industrial domains:

• Metal Buildings
• Warehouses
• Manufacturing Facilities
• Aircraft Hangars
• Agricultural Sheds
• Commercial Complexes
• Metro Stations
• Shopping Complexes
• Tunnels
• Steel Plants
• Power Plants
• Chemical Plants

Essentially any structure with large exposed roofing area needing strong purlin supports employs these lightweight but very sturdy cold formed sections in huge quantities.

20-30% savings can be achieved on production costs with the right machine specification.

Pros and Cons of Sigma Purlin Forming Machine

FAQs

Q: What materials can be formed on sigma purlin forming machine?

A: These machines are designed for roll forming steel coils and sheets. Galvanized steel is most common but some lines can also process stainless steel, aluminum and other metal coils.

Q: Can one machine make different sized purlins?

A: Yes, by adjusting the cutoff shear and line speed different purlin lengths can be produced from the same machine. However width is fixed as per tooling limit.

Q: What automation types are available?

A: Options range from semi-automatic needing manual offloading to fully automatic lines with inline stacking, bundling and even packaging. Level of automation depends on production volumes and budget.

Q: What regular maintenance is required?

A: Requirements involve lubrication, tension checks, calibrating shear cut length, wear check on forming rollers, sensor cleaning and overhaul of hydraulic/electrical components. Annual servicing contracts are highly recommended.

Q: What is the typical delivery time?

A: For standard designs delivery takes 8-12 weeks. For customized lines with engineering it may take 12-16 weeks. Reputed large manufacturers have capability to deliver multiple lines simultaneously.
