Key Features
Fast Size Change
No roller replacement is needed. The web width can be adjusted steplessly via computer with one click.
Web width range: C purlin 100–400mm, Z purlin 120–400mm.
Flange and lip sizes will be adjusted synchronously automatically, which greatly reduces downtime for specification change.
Stable High-speed Operation
It adopts high-power servo motor for main drive. The maximum line speed reaches 36 m/min, and the comprehensive working speed with punching keeps 15–22 m/min.
There are 24 forming stands in total, ensuring the finished profile keeps straight without distortion.
Precision Heavy-duty Configuration
Main shaft: 40Cr quenched and tempered alloy steel, shaft diameter φ90/φ75, high rigidity and anti-bending.
Rollers: Made of Cr12 die steel with quenching and polishing treatment, wear-resistant and no scratches on galvanized strips.
Control system: Windows industrial computer. It supports importing orders via USB and remote parameter transmission, and can connect with production management software. The tolerance of length and hole position is controlled within ±1mm.
Integrated Punching & Cutting
The whole line automatically completes uncoiling, punching, forming and fixed-length cutting continuously with unattended operation.
