Automatic Special Shape C Channel Cold Forming Steel Rolling C-Shaped Purlins Forming Machine
This machine processes coiled metal sheets into C-shaped purlins. The production line integrates key functions such as material handling racks, front punching,C-shaped purlins and C-section steel forming, and cutting. All these processes are fully automated under PLC control. The system utilizes AC frequency conversion technology to regulate speed, enabling seamless and continuous production. It is an ideal choice for the steel structure and cold-formed metal processing industries.
The feeding frame consists of components such as an uncoiling frame, mandrel, and braking mechanism. The uncoiling frame is a welded steel plate structure. At the end of the main shaft, a square-head adjusting screw controls expansion and contraction, while radial movement of the tension pad on the mandrel secures or loosens the steel coil. The braking mechanism relies on friction between the brake band and brake wheel, with an adjustable bolt to fine-tune the unwinding speed.
