Detailed Content
On a purlin forming line, steel coil goes through decoiling, feeding, forming, and cutting before it becomes a finished product. Smooth operation depends on how power transfers between each stage. A purlins bending machine needs a drive system that matches the production flow. This machine uses a 5 ton decoiler, a gear box drive, and a hydraulic station to support continuous operation.

This equipment mainly processes purlin structural parts and frame profiles for steel structure buildings, industrial plants, and warehouses. It handles galvanized steel and cold rolled steel from 1.2 to 2.7 mm thick.
A rollforming purlin machine with this configuration can produce roof purlins, wall purlins, and frame support components with cut to length control.

The decoiler is the first stage
On a purlins bending machine, the decoiler carries the steel coil and uses hydraulic expansion to fix the coil core. A speed sensor monitors the main machine speed and automatically adjusts the feeding rate. The 5 ton load capacity and 600 mm max coil width define the coil size this equipment can handle.

Gear box transmission
For this rollforming purlin machine, the forming main machine gets power from a 30 kW main motor. Power transfers through the gear box to each roller shaft.

Hydraulic system for punching and cutting
The hydraulic station uses a 7.5 kW motor and 46# hydraulic oil. It provides power for punching and cutting operations. For a hydraulic purlin machine, this system drives the punching and cutting process in the line.


Decoiler and main machine speed coordination
A purlins bending machine with a speed sensor on the decoiler can automatically adjust the feeding rate to match the main machine speed. This coordination helps keep material flow consistent between decoiling and forming.
Hydraulic system for punching and cutting
The hydraulic station provides power for punching and cutting. For a hydraulic purlin machine, this setup supports the cutting process after forming.


To match a purlins bending machine to your production, consider the coil load capacity and coil width, the decoiler speed control range, the gear box transmission, the hydraulic system power, and the main motor power and forming stations. These factors should align with your material thickness, profile section, and output requirements.
If you are planning a purlin production line, you can discuss the specific power and transmission configuration based on your material and profile needs. A purlins bending machine configured to your production requirements is the goal.
