Ⅳ、Machine Pictures (updating)

Main Components:

1. De–coiler

De-coiler Type: Manuel de-coiler

Weight capacity: 5.0T

2. Feeding and Leveling Device

It used for making the material flat before feeding into the roll forming machine. use handler bar to operate the leveling up and down.

3.Hydraulic Pre-Punching

PLC control punching system.

Punching Type: Hydraulic Punching

Distance of the hole can be adjusted manually by handlebar (Transversal) ; Longitudinal position is to be adjusted by inputting parameters into the PLC.

4.Pre-cutting system

Adopts post cutting, the cutting blade material is Cr12 with quenched treatment, after cutting, there is no wasted material.

advantage of pre-cutting system:

1. pre cut takes 4 seconds to cut.
2. the purlin without any burrs.
3. no need adjust after changing size.

5.Rolling Forming System

• Main motor type: 3 phase asynchronous motor
• Driving Type: Chain

Speed of forming: 15-18m/min( 30m/min without punching holes)

 Roller : 19groups rollers.

Material of main shaft : NO.45 steel

Changing sizes: Automatic, change sizes by press button.

6.Post-cutting system—main cutter when chose post-cutting system.

Cutting material:  Cr12

For C and Z profile cutting

7. Product Support Frame

• The length of product support frame : 6m 

8. PLC Control System

Control the quantity &punching length & cutting length automatically

In English

The Machine will be stopped while it is punching and cutting

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
