Color Steel Square Downspout / Downpipe Roll Forming Machine For Rainwater Pipes 

Description:

The process of roll forming is one of the simpler manufacturing processes.

It typically begins with a large coil of sheet metal, between 1 in. and 20in. in width, and 0.004 in. and 0.125 

in. thick, supported on an uncoiler. The strip is fed through an entry guide to properly align the material as it passes through the rolls of the mill, each setof rolls forming a bend until the material reaches its desired 

shape. Roll sets are typically mounted one over the other on a pair of horizontal parallel shafts supported bya stand(s).

Side rolls and cluster rolls may also be used to provide greater precision and flexibility and to limit stresses 

on the material. The shaped strips can be cut to length ahead of a roll forming mill, between mills, or at the 

end of roll forming machine.

Main Equipment:

1. 3T manual de-coiler

-- Mode of expand &fight: inner expand &fight by manual

-- Way of feeding: manual

2. Feeding device

-- Adjustable center of the forming rollers and of sufficient length to prevent lateral movement of the strip on its entry to flattener.

-- Feeding type: adjustable

-- Entrance and guide roller

3. Roll Forming Machine

-- Transmission: by chain, one inch, Single line

-- Roll former has leveling bolts in the base for adjust the leveling

-- Machine base frame adopt H beam welding steel

-- In the main roll forming machine have 1 button for urgency stop if happen any malfunction.

-- Machine adopt metal wall structure as station

-- To avoid accidents, all of drive part adopt protect cover

4. Post Cutting System

-- Profile transversal cutting device units allowing to cut the bent profile without damaging the metal   coating and to assure a smooth cutincluded

 -- Cutting after forming: Cut the sheet after roll forming to required length

 -- Uses two hydraulic cylinders for operation shall include a flow regulator to achieve a uniform lowering knife.

  -- Cutting power by hydraulic

  -- Length measuring: Automatic encoder length measuring

  -- The cutting sequence is also contained and controlled by the same PLC program

  -- Tolerance of length: +/- 1.5mm for each piece end product

5. Hydraulic station

6. Control desk

 -- Programmable setting of profile length and quantity

 -- Programmable cutting unit, various lengths in one programming cycle without

 quantity restrictions (without stopping the operating equipment): will be provided.

  -- 5 groups datas can be set in one time

 -- Automatic stopping of the equipment after completion of the cutting programmewill be provided.

 -- Computer used to control length & quantity. Machine will automatically cut to

length and stop when required quantity is achieved

 -- Length inaccuracy can be amended easily

 -- Control panel: Button-type switch and touch screen

 -- PLC brand: Panasonic

 -- Frequency converter brand: Yaskawa

-- Touch screen: Taiwan Weinview

7. Rainspout / Downpipe elbow machine:

-- Control system: Strong electrical current

-- Max bend angle: 90°

-- Function: bend and fasten at the same time

-- Speed of bend: 0-5m/ min
