Working Principle

The working principle of mould cutting downpipe roll forming machine involves sequential bending and shaping of metal coil feedstock through consecutive roller die stations to gradually form an angled downpipe profile.

Integral punch presses or other secondary operations create holes, notches and hardware fits. An additional mould cutting module shears the formed piece from the strip, creating finished drain pipes ready for installation.

Benefits over manual methods include:

• Automated process for high production rates
• Precision calibration and sizing
• Integrated features like holes, slots, tabs
• Standardized outputs with minimal variability
• Limited manual labor aside from setup

Table 1 highlights how max strip width, metal thickness, running speed and number of forming stations differentiate roll former models.

mould cutting downpipe roll forming machine Production Process

A complete downpipe roll forming production sequence comprises:

1. Loading raw metal coils
2. Decoiling and feeding strip through guides
3. Forming stations shape profile
4. Hardware insertion – tabs, holes, notches
5. Shearing die punch separates pieces
6. Exit conveyor stacks finished drain pipes

The process allows swift precision part creation with minimal manual input between automated steps. Operators simply maintain equipment settings and offload finished downpipes.

Materials and Customization

Metals well-suited for mould cut downpipe roll forming include:

• Hot dipped galvanized steel – durable exterior corrosion protection with zinc coating
• Prepainted steel – colored aesthetic coating
• Aluzinc steel – zinc-aluminum alloy coating
• Copper – traditional material with long service lifespans
• Stainless steels – premium grades like 304 and 316

Profile customization options:

• Dimensional sizing to fit existing rainware infrastructure
• Square, rectangular, round and oval shapes
• Mounting tabs, seam caps and other hardware
• Decorative stamped patterns
• Matching elbows and connector fittings
• Rainwater filter basket attachments

This flexibility suits residential buildings along with large commercial roof drainage product needs.

Installation, Operation, Maintenance

To install a mould cutting downpipe roll former:

• Offload components using forklift/crane
• Anchor reinforced frame to level concrete
• Wire necessary electrical, pneumatic lines
• Position decoiler, loop feeder, stations per design
• Insert tooling packs based on profile

For operation:

• HMI and PLC automate actual roll process
• Input production variables – width, thickness, lengths
• Monitor strip flow, shearing, finish quality

Maintenance best practices:

• Inspect/replace forming rollers
• Check hydraulic fluid levels
• Clear metal fines
• Test emergency stop buttons
• Audit safety mechanisms

Proactive preventative maintenance protects operational uptime on downpipe roll forming equipment.

In summary, automated roll forming generates superior downpipe components over manual methods – both in productivity, consistency, accuracy and integrated hardware capabilities.

Frequently Asked Questions

Q: What drainage capacities can downpipe roll formers accommodate?

A: With large width capacities, high volumes like multi-story buildings, stadiums, industrial plants can be matched to local precipitation data.

Q: How long does a downpipe roll former tooling pack last?

A: Approximately 40,000 linear feed meters of strip. For two daily 10 hour shifts at 20m/min line speeds, changeover comes around every 2 months.

Q: Can elbow fittings be created on the same downpipe roll line?

A: Yes, some advanced models integrate elbow forming stations or secondary endformers to produce right-angle downpipe connectors without requiring manually welded elbows.

Q: What factors affect downpipe roll former machine pricing?

A: Key considerations include: overall line width, material thickness capacity, secondary processing features, construction materials used, brand reputation, support services, and customization capabilities.

Q: Can a small shop produce their own customized downpipes?

A: Lower cost manual bending brakes allow small scale custom downspouts but labor, precision and consistency issues make automated roll forming preferable for volume production runs.

Q: How are decorative patterns added to downpipes?

A: Textures, logos and styling can be built into the profile tooling. Painting is also possible but may require pre-treatment to ensure adhesion suitability on various drainage material surfaces.
