C60-250 Purlin Roll Forming Machine C purlin Quick Change1.2-2.5mm roll forming machine
The advantages of C purlin machine AUTOMATIC size-change type are as follows:1.Produce different purlin size without changing rollers or spacers. No need changing cutter for different size.
Easy operation, low maintenance cost. Infinite sizing(any size within machine range),help to save material. Optional Punch hole at any position of purlin web side and flange side.

3.Other details of C purlin roll forming machine
Suitable for material with thickness 1.2-2.5mm
Shafts manufactured from 45#,Main shaft diameter=φ80mm,precision machined
Motor driving,Gear chain transmission, 16 rollers to form and 7 rollers for straightening and levelling
Main motor=15KW , Frequency speed control. Forming speed approx.18m/min
PLC Control System (Touch screenbrand:German Schneider Electric/Taiwan WEINVIEW,
Inverter brand:Finland VOCAN/Taiwan DELTA/ALPHA,Encoder brand:Japan Koyo/OMRON)
Just adjust required WEB,HEIGHT and LIP by hand wheel with the help of
position clock(with digit display for easy operation) on it,
and then input the required production data on the touch screen.
It takes only 5-10 minutes to finish all. No need to change rollers or spacers or cutters
like traditional old style machine (which takes over 45 minutes for each production size changing).
Combined with: PLC, Inverter, TouchScreen, Encoder, etc
