auto cz purlin machine

XINNUO CZ purlin roll forming machine is an automatic industrial device for continuous cold - roll forming of galvanized/cold - rolled steel coils (1.2-3.0mm thick) into C - shaped and Z - shaped structural purlins, which support building roofs/walls. It integrates decoiler, leveler, PLC - controlled punching/cutting units and C/Z interchange modules, enabling quick profile switching.

Roller: 19groups rollers. Main rollers of this line are made by Cr12 mould steel material, all treated by full CNC precision machines

Shaft: Shafts of rollers are tooled by grinding machine for two times to ensure the precision of final product.

Material of main shaft: NO.45 steel

Machine Components

1.De–coiler

De-coiler Type: Manuel de-coiler

Weight capacity: 6.0T

2.Feeding and Leveling Device

Material: GCr15, It used for making the material flat before feeding into the roll forming machine.

3.Pre-cutting system

This cutter is for last piece cutting. Cutting controlled by PLC

4.Rolling Forming System

Main motor type: 3 phase asynchronous motor

Driving Type:  Chain

5.Post Punching System

Punch on roll formed product. PLC control punch quantity and horizontal position; vertical position adjust by manual Punching sizes can be changed;

6.PLC Control System

Control the quantity &punchinglength & cutting length automatically

PLC must be able to keep in memory which profiles are “inside” the machine even after the machine is stopped.

Automatic Length measures and quantity counting.

Program batches with different profile lengths with no waste.
