New Model CZ profile changeable C Z Purlin Roll Forming Machine

WHAT'S C Z PURLIN MACHINE?

This C Z purlin forming machine is used to manufacture series of C and Z sections. The machine is mainly composed of uncoiler, flattening device, punching device, cutting equipment, roll forming machine, collection table, hydraulic station, and control system, etc. It can produce 100 - 300 wide C and Z purlins, height from 45 - 80mm. The raw material is cold rolled steel, galvanized steel, etc, material thickness is 1.5 - 3mm.

WHAT'S THE PROPERTIES OF THIS MACHINE ?

One machine can produce C and Z sections.  Rotate the forming stands, can easily change C to Z production. The width and height adjusting by motors, directly operate on touch screen.

Machine frame heat treatment for interior stress release, the surface is precision milled. Rollers, shafts are using high grade steel,  ensure the durable and reliable quality.

Online has two sets of punching device, to punch the connecting and screw holes. After roll forming there is calibrating rolls to straight the profiles

Machine adopts PLC and touch screen operating, all parameters can be set on the screen. Very easy to manage.

HOW TO OPERATE ?

The machine is totally controlled by PLC system. So only by inputting related production data such as number of products, length and punching dimension, users can start this machine to do manufacturing. If users want to adjust this machine or something else, they have to stop the machine first and carry out relevant operation.

FEEDING DEVICE

1 .Adjustable center of the forming rollers and of sufficient length to prevent lateral movement of the strip on its entry to flattener.
2 .Feeding type: Adjustable
3 .Feeding type: Adjustable
4 .Entrance and guide roller: Diameter is ¢65mm, material is SAE1045, HRC48-52° surface with chrome

LEVELING DEVICE

1 ..The quantity of leveler rolls must be planned according to thickness 1.5mm to 3.0mm.
2 ..Flattener roller: Upper is 3 rollers, down is 4 stations(total is 7 rollers)
3 ..Flattener roller material: SAE 1045 thermal treatment hardness 48-52 HRC.
4 ..Diameter of flattener shaft: ¢76mm, material is SAE 1045, hardening and tempering
5 ..Drive by motor: 4kw AC motor (guomao of china)

PUNCHING HOLES DEVICE

1 ..Base on customer provide punching drawing, this machine need adopt two units hydraulic punching system
2 ..The punches will be connected to a single hydraulic unit having tank, motor, pump, pressure control valves, pressure gauges, solenoid valves, hydraulic hoses, all designed to operate safely at the required operating pressure; also to facilitate changing O-ring they must be of standard size, also consider suitable cooling unit.
3 ..The punches and dollies will be CR-12, hardness HRC 58-62 and chrome coating both punches and dolies should be easily replaceable without requiring disassembly of complete units.
4 ..The whole punching operation should be automated and controlled by a program installed in the PC which is located in the operator's console.
5.. Hydraulic power: 5.5kw

PRE-CUTTING DEVICE

1..Cutting type: Hydraulic, connect with the punching hydraulic unit
2.. Cutting power by hydraulic, 5.5KW AC motor
3 ..Hydraulic working pressure: 12-16Mpa
4 ..Cutting before forming: Cut the sheet before roll forming to required length
5.. Feeding of the last cut profile from the equipment: Automatic if the length of the last profile is not less than 1500 mm
6 ..Profile transversal cutting device units allowing to cut the bent profile without damaging the metal coating and to assure a smooth cut
7.. Cutting motion: The roll forming part is NON-stop when cutting
8 ..Material of blade:Cr12 with heat treatment
9 ..Length measuring: Automatic encoder length measuring, brand: Omron
