Full Automatic C and Z Purlin Roll Former

Hebei Xinnuo Roll Forming Machinery Co., Ltd. has built cold roll forming equipment since 1995 and runs a factory of nearly 100,000 square metres in the Botou Economic Development Zone, Hebei, with 11 large workshops, 50+ high-precision CNC machine tools and more than 30 years of experience. This full automatic C and Z purlin roll former suits steel structure work that needs both profiles from one line.

One forming unit handles both sections. Changing from a Cee purlin to a Zee purlin takes about ten minutes without a roller change, and web height adjusts from 80 mm to 300 mm. One line therefore covers the purlin sizes of a whole project.

A PLC touch screen runs the line. Purlin parameters are entered once and stored, so a repeat order is recalled in one click rather than being set up by hand, and automatic length cutting and counting continue without an operator. Purlin tolerance holds at about ±0.5 mm.

Punching and cutting are integrated in one hydraulic station. A three-row punching unit forms round and oblong holes on the web and flanges with positions set from the PLC, and the hydraulic cutter shears the finished purlin with clean, burr-free edges that need no secondary finishing. The pump station runs at 16–20 MPa and the Cr12 cutter blade is hardened.

Forming rollers are hardened and hard chrome plated, so they resist wear and hold the profile after long runs. The line accepts galvanised, colour-coated and cold rolled strip between 1.5 mm and 3.0 mm thick at 235–345 MPa.

Forming speed is adjustable, so an urgent small batch runs slower while volume orders are pushed harder without changing tooling. The main frame is heavy welded steel with anti-vibration reinforcement, which keeps the roll shafts steady at production speed.
