C80-300 Type Fully Automatic C Purlin Roll Forming Machine

Main Workflow:

Uncoiling: The steel coil is placed on the uncoiler, automatically unfolded and leveled.

Guided feeding: The strip is guided into the forming main machine.

Roll forming: The strip passes through multiple groups (usually more than a dozen to more than twenty) of forming roller stations in sequence. Each roller applies precise bending force to the strip, gradually changing its shape from a flat plate to the final C-shaped section.

Online punching/stamping (optional): Some models integrate punching units during or after forming, which can automatically punch connection holes or other marks on the web or curling edge.

Length measurement and cutting: The continuous C-shaped steel, after forming passes through the measuring device (encoder). When the preset length is reached, the high-speed cutting device (usually a flying saw or hydraulic punching shear) is activated and cuts instantly without interrupting the continuous operation of the forming host.

Discharging and stacking: The cut single C purlin is transported out of the host and automatically collected, aligned and stacked into bundles by the stacking system.

Control system: PLC and HMI (human-machine interface) control the entire process, monitor equipment status, store production data, set and switch production parameters for products of different specifications.

Main Applications and Advantages:

Application: Mainly used in the steel structure construction industry, producing roof and wall purlins for buildings such as factories, warehouses, gymnasiums, supermarkets, etc.

Advantages:

High efficiency: Fully automatic continuous production, the speed can reach more than ten meters to dozens of meters per minute, and the output is much higher than that of single-piece stamping or semi-automatic equipment.

High precision: The molding size is accurate and the product consistency is good.

Save materials: Continuous production reduces the loss of material head and tail.

Save labor: High degree of automation and less operator requirements.

Flexibility: A machine can produce a variety of C-shaped purlin specifications with different heights (within the range of 80-300mm), different thicknesses, and different curling sizes by replacing rollers and adjusting parameters.

Reduced costs: The overall production efficiency is high and the unit production cost is significantly reduced.
