Product Description

Brief Introduction

This roll forming machine is for steel sheet or aluminium sheet cold-form industries. It can form the steel sheet according to customer’s requirement continuously, automatically cut to length. The equipment adopts PLC control, AC frequency and adjusting the speed technology, and it realize the continuous automatically production.

Main Components
Decoiler




This decoiler is passive type, could load coil by expand the arms to change coil inner diameter to make coil tightened. It’s easy to operate and economical solution
Guiding Device



Adopt guiding bar and sliding block to control the width and position of the steel sheet. The coil is guided in the correct position and passed to the roll forming system. Can adjust the guiding bar with loosing the fixing bolts to feed sheet in right position. It’s fixed structure to make sure can not move easily. 
Forming System




Roll forming system consist of machine frame, transmission system, electrical motor and roll forming system. 

A. Machine Frame

Machine frame adopts welding structure with shot blasting and painting treatment

B. Rollers

All rollers material adopt high quality No.45 steel, with hard chrome coated on surface, all treatment by full CNC machines.

C. Shaft

All rolling shafts are made by high quality No.45 steel with quench and temper treatment, which could use for long tern without deformation. 

D. Supporting Structure

Rolling shafting supporting structure type is steel wall and welded with the basement together to have rigidity. 

E. Transmission

Cyclical pin gear speed reducer motor driven, the back/forward roller driven by chain, part of upper/lower rollers driven by gear

F. Adjust

Adjust the screw bar manually to adjust the distance between upper/lower rollers for difference thickness of sheet. 

Cutting Device

A
Adopts post cutting, the cutting blade material is Cr12 with quenched treatment, after cutting, there is no material wasted.
B
 Adopts welded frame for good rigidity.


C

The cutting action is droved by hydraulic station which guarantees the precision of cutting and low noisy, long life.
PLC Control System

A
Adopts PLC control and frequency adjust speed, length measurement encoder calculation technology, realize the automatic production.


B
Adopt high quality components, such as Mitsubishi PLC, transducer and touching screen, Omron mini-relays, Schneider AC contactor, switches.
C
The system uses modular structure with reasonable wiring arrangement.
