Roll Forming Line

Description features:Roll forming plant contains the following machines:
Decoiler
Straightner
Punching unit
Roll former
Shearer
Decoiler:
The decoiler is an important part of any roll forming plant. It is used to hold sheet reel during roll forming or during punching and shearing.
The sheet reel is fixed on the axe of decoiler; then the axe diameter is increased to fit the reel inner diameter.
Technical specifications:
Minimum reel inner diameter 270 mm
Maximum reel inner diameter 450 mm
Maximum reel outer diameter 1100 mm
Reel width from 150 mm to 470 mm
Reel maximum weight 4 ton
Decoiler overall dimensions 113cm x 53cm x 86cm
Decoiler weight 218 k. G.
Straightner:
Straightner machine is used in roll forming plant to help in reel uncoiling in addition; it is used as a feeding unit to the next step in production line.
Technical specifications:
Number of straightening rollers 2 / 3.
Number of feeding rollers 2.
Vertical adjustment of straightning 25 mm.
Maximum sheet width 25 cm.
Maximum sheet thickness 2 mm
Drive motor 8 hp electric motor 380 volt.
Punching unit:
This is a 30 ton hydraulic punch press unit comprising of a press frame carrying one fixed die holder. The top plate of the hydraulic press carries a high speed double acting hydraulic cylinder.
Specification

Feeding set on separate hydraulic motor
Overall dimensions 77cm x 68 cm x 163 cm.
Gross weight 450 kg.
Roll former:
Roll former is used to produce a regular beams in identical dimension that is commonly used in construction and industrial applications.
Roll former can also produce many corrugated sections by passing a strip of sheet metal between a set of rollers sequentially and the strip section changes gradually at each roller up to final shape.
Technical specifications:
Roll former is use to produce commonly use beams all in identical dimensions.
Rollers are fixed on a robust base to ensure stability during operation.
Each roller is mounted on two roller bearings.
Roller sets could be changed to work on different cross section or different thickness.
Roll former is operated from electric motor 12 hp and 380 V.
Roll former is supplied with tool box locate in roll former base and opened from side.
Former can form sheet metal with thickness up to 2 mm and width up to 25 cm.
Vertical adjustment of rollers 50 mm from 80 mm to 130 mm.
Machine speed is controlled from side control panel.
Output speed of products is 18 m / min.
Number of stations for rolling are 12.
Overall dimensions are 290 cm. Length by 65 cm. Width by 104 cm high.
Gross weight 750 kg.
Shearer:
Shearer unit has been produced for the cold rolled forming industry. The shearer comprises of a hydraulic shear which would be integrated on a production line with other roll forming equipment for producing cold rolled sections. It could be stand alone or integrated with production line.
Specification
