Overview Of Half Round Gutter Roll Forming Machine

 

Half round gutter making machines, also called half round rain gutter machines or demi-circle gutter roll formers, transform metal coil/strips into curved U-shaped profiles used as roof drainage systems.

 

They create half cylinder shaped gutters by roll forming the sheet material through a series of roller dies that progressively bend the strip into the desired contour. The formed metal gutters collect and drain rainwater from rooftops preventing water damage.

 

Benefits of half round gutter roll forming:

 

• Continuous, automated production of long gutter lengths
• High output rate up to 18 m/min
• Uniform profile and smooth surface
• Cost-effective versus other methods
• Easy customization of dimensions
• Reduced labor compared to manual bending

 

Drawbacks:

 

• High initial capital expenditure
• Regular maintenance required
• Limited profile shapes

 

Half round gutter making machines allow efficient, high-volume production of rainwater collection products for houses, garages, greenhouses etc.

 

This guide provides a comprehensive overview of half round gutter roll formers covering: working principle, types, components, processes, customization options, installation, operation and maintenance procedures.

 

 

Working Principle Of Half Round Gutter Roll Forming Machine

 

The working principle involves:

 

• Feeding: Coil/strips enter an unwinding unit
• Accumulation: Accumulator tower stores and feeds sheet at constant speed/tension
• Roll forming: Roller dies bend metal through progressive stages into half cylinder shape
• Cutting: Profiles cut to required lengths
• Output: Formed gutters exit to stock

 

Key stages in half round gutter roll forming process:

 

1. Material Feeding: Coil/sheet loaded onto powered unwind reel entering through guidance rolls

2. Accumulation: Accumulator tower stores and releases fed stock attuned to line speed

3. Pre-forming: Initial roller dies make light bends

4. Forming: Main roll forming stations make incremental bends up to 180 degrees for half round shape

5. Calibration: Final rolls calibrate profile

6. Cutting: Flying cut-off shears cut gutters to length

7. Output: Formed gutters exit to stock conveyor/stacker

 

The sheet/coil material undergoes a series of bends by contoured rollers to gradually form the half round contour. Correct roller design and precise gaps between rolls are crucial for profile accuracy.
