oem c purlin roll forming machines are used to continuously bend and form metal coils into C-shaped purlin beams for the construction industry. As an original equipment manufacturer (OEM), these machines can be customized to produce purlins of different sizes and specifications per client requirements.

Introduction to oem c purlin roll forming machine

Roll forming is a continuous bending process that forms long metal sheets or coils into customized profiles using a series of successive rolling stands. OEM purlin roll formers transform plain metal coils into finished C or Z-shaped purlins through the following steps:

Material Feeding

Uncoiling and feeding metal coils into roll forming line
Alignment and edge preparation before forming
Controlling feed speed in sync with rollers

Profile Forming

Progressively bending sheet through consecutive roller stages
Each stand incrementally forms desired ribbing and shape
Connects to shape cutter for final custom purlin length

Design and Customization

Machines can form C or Z purlins of different sizes
Specialized tooling for custom purlin dimensions
Operators program and adjust forming parameters

OEM purlin forming lines offer:

• Higher outputs up to 18-25 meters per minute
• Quick roll and die changeovers
• Option for inline punching and shearing
• Automated control systems for efficient operations
• Customization for specialized purlin specifications

Compared to manual bending methods, purlin roll formers provide consistent, superior quality beams at higher production volumes necessary for large construction projects.

Working Process of OEM C Purlin Forming Machines

The working principle behind purlin roll forming involves continuously shaping flat metal stock into final C or Z ribs by passing it through a series of rolling dies in a sequential bend-form-bend process:

Step 1) The uncoiled raw material from a metal coil is fed into the feed table which straightens and aligns the strip before the first forming stands.

Step 2) The metal sheet then passes through a series of rolling stations, each with a set of top and bottom rollers.

Step 3) At every stand, the sheet is incrementally bent into the shape of a C rib with specific dimensions based on client requirements.

Step 4) Specialized tooling is used to create different purlin sizes – the rollers have machined contours that impart desired bending during each rolling phase.

Step 5) Finally, the formed C profile sheets goes to the cutter which shears it to customizable lengths as per order specifications.

Step 6) Formed purlins exit the line through a set of decoiler rolls for safe offloading.

OEM purlin lines are equipped with programmable automation to control this forming process and produce beams efficiently in large volumes. Operators can set the tandem rolling stations to create the exact purlin size and cut lengths as needed in each client order using the HMI panel.

Installing OEM Purlin Roll Forming Equipment

Proper installation is key for peak performance of purlin roll lines. Here are key steps:

Site Preparation

• Level concrete or steel foundation
• Sufficient working area for safe operation
• Proper shed or enclosure for weather protection
• Adequate power supply near equipment

Transportation & Unloading

• Use cranes, forklifts to unload components
• Take care not to damage parts during shifting

Positioning & Alignment

• Assemble stands, tables as per drawings
• Precision alignment of rolling stations
• Proper anchoring and machine stability

Trial Runs & Testing

• Check uncoiler, hydraulic power, controls
• Run without material to verify functioning
• Parameter tweaking to validate forming
• Inspect if system meets specifications

Taking appropriate measures during installation prevents potential issues that can disrupt functioning after commissioning.

FAQ

Q: What sizes of C purlins can be formed on OEM roll lines?

A: Standard machines can produce 75 to 250 mm depth symmetric C profiles. Customized roll pass design allows purlins up to 300 mm depth if required.

Q: How to determine correct line speed for quality purlins?

A: Typical speeds are 18-25 m/min based on material grade. Heavier gauges may require slower forming for proper profile development without defects.

Q: What processes are needed to join formed purlin sections?

A: Self-tapping screws can connect purlin beams on site. For very long spans, specialized presses join sections through crimping or embossing to get required overlap strength.

Q: How to ensure dimensional accuracy of finished purlins?

A: Precision ground steel rollers, accurate feed measurement systems, tension controls, and depth stops on cutter are some ways purlin quality consistency is achieved.

Q: What auxiliary equipment can be added to purlin roll lines?

A: Decoilers, stackers, straighteners, hole punching, specialized cutting and bending machines can be integrated for secondary processing as per client needs.
