CZ rolling forming machine

CZ changeable Purlin Forming Machine is an equipment that produces C/Z shaped steel channels continuously out of galvanized or cold rolled steel strips from feeding, punching for holes, bending and cutting.

CZ purlin machine options

After more than 10 years developing and searching  according to different customer requirements, here we desinged the following types CZ purlin machine

Drawing profile and size change

Punching Drawing :

Here is one example drawing profile for your reference. As default we give 4 punching station,  if you have more types we can add. Normally it has side holes and bottom holes.

2.Leveling part

˃ Leveling system: top 3 and bottom 4 rollers, with extra 2 couple of pinch rollers.

˃ Leveling roller diameter: Ø 80/100mm

˃ Rollers are solid shaft with heating treatment, polishing and galvanizing.

˃ Guiding system including guiding shaft and guiding rollers, their width is adjustable in order to  suit for various steel strips.

Main Rolling Forming Machine transmission part

˃ As to the main rolling forming machine, transmission, we have three options:

˃ Normal motor, brand optional like Simens motor or others.

˃ Servo motor.

˃ Hydraulic power:

Main rolling machine

1. Roll stand: 18 stations, chain transmission.

2. Roller material: GCr15 with heat treatment, polishing and galvanizing.

3. Main motor: hydraulic drive, power: 22KW, tank: 500L, with air cooling system

4.Main shaft: 40Cr with heat treatment, polishing and galvanizing.

5. Machine frame: welded by iron plate, with flat planer finish machining. The  levelness is measured by electronic level meter.

6. Machine surface adopts powder coating, coating before assembly.

7. CZ Interchange: turn over the roller box to 180 degree.

Universal Cutting System

Material of cutter: Cr12MOV, quenching.

Universal cutters: one for size (80-200mm), another for size (200-300mm)  Cutting length, cutting pieces, and punching are controlled by PLC.  Punching & Cutting when machine stop.

For this part, when sizes changing, you need to adjust the height and width  by hand.

PLC control part Power Supply & Control System
