Shelf Panel Roll Forming Machine: Manufacturing Shelves

परिचय

Roll forming is a metal forming process used to create long profile sections with a uniform cross-section. It works by progressively bending a strip of sheet metal through a series of roller dies until the desired cross-sectional shape is obtained. Roll forming machines are highly efficient and economical for producing high volumes of standardized parts with great precision and consistency.

One common application of roll forming technology is in the production of shelf panels used in retail stores, warehouses, workshops and homes. Shelf panel roll forming machines can rapidly produce strong, lightweight shelves in varying lengths from coiled steel. This saves metal fabrication shops time and money compared to cutting and welding individual shelf components.

In this article, we will look at how shelf panel roll forming machines work and their key components. We’ll also discuss the benefits of roll formed shelf panels and tips for setting up your own roll forming line for shelf production.

How Shelf Panel Roll Forming Machines Work

A shelf panel roll forming machine forms metal coil into shelf profiles through a series of sequential bending and shaping operations. The process allows shelves of various sizes to be continuously produced from a single strip of raw material.

Here are the key steps in how shelf panel roll formers work:

1. Feeding Coiled Metal into the Machine

The input material for the roll forming process is metal coil. Standard widths for shelf production are around 24” to 48”. The coil is loaded onto a de-coiler which feeds the strip through the machine.

2. Shearing the Metal

The strip is first cut to the required shelf length by a shear or cutting device. The shear may be at the start of the line or further downstream after some initial forming.

3. Forming the Profile

The cut length of metal then passes through a series of roller dies. Each die makes a small bend until the final shelf shape is progressively achieved.

4. Other Shaping Operations

Additional operations may be integrated into the roll former for extra functionality:

  • छिद्रण – Holes for shelf brackets are punched into the profile.
  • Notching – Notches are created for shelf connections and fittings.
  • एम्बॉसिंग – Surface patterns are pressed into the material.
  • Cut-offs – Individual shelves are cut from the profile at the desired lengths.

5. Output of Finished Shelves

The formed shelf panels are automatically stacked at the output end, ready for hardware insertion and final inspection. Conveyors often transfer the completed shelves to a packaging area.

Main Components of a Shelf Panel Roll Former

Shelf panel roll forming lines contain a number of important components that work together to create the finished shelves:

Coil Handling Equipment

  • डी-coiler – Feeds the strip material into the roll former. Has powered unwinding mechanism to provide tension control.
  • Coil car – Holds the coil being fed into the machine. Allows quick coil changeovers.
  • Straightener – Removes coil curvature and straightens the strip before forming. Uses articulated rolls or pyramid arrangement.
  • Feed table – Supports and guides the strip into the roll former. Has adjustable height and side guides.

Roll Forming Stations

  • Roller dies – Progressively form the material through a series of bending and shaping stations. Over 20 stations is typical.
  • Forming rolls – Located between stations to support the material during forming. Rotate to avoid scratches.
  • Roll housings – Hold and position the roller dies at each station. Allow quick die changeouts when profile is altered.

Shearing Device

  • Rotary shear – Rotating blades cut the strip to length at the start or intermediate stage of the line.
  • Guillotine shear – Straight blades shear material at the final stage after all forming is complete.

Additional Processing Stations

  • Punching press – Punches holes for shelf brackets into the profiles.
  • Notching machine – Creates notches in the shelves for connections. Based on milling or punching.
  • Embossing station – Uses textured rollers to imprint patterns into the metal surface.
  • Marking – Prints identification information like batch numbers on the shelves.

Material Handling

  • Conveyors – Transports shelves from one station to the next. Used for loading, unloading and transfer.
  • Stackers – Automatically stacks finished shelf panels exiting the line. Allows efficient bundling.

All of these components are controlled from a central control panel. The line is also equipped with safety barriers and sensors to ensure safe operation.

Benefits of Using a Shelf Panel Roll Former

Here are some of the main advantages of using a roll forming machine for shelf production:

  • High productivity – Roll forming lines produce shelves 3-10 times faster than fabrication methods. Over 100 feet per minute is possible.
  • गाढ़ापन – Roll formed shelves have an identical profile along the length. Bends and holes are precisely aligned.
  • Material savings – Roll forming reduces material waste by forming shelves from narrow coil strips rather than wide sheets.
  • Adaptability – Roll formers can produce various shelf designs by changing the roller dies. Fast size changeovers.
  • Strength – The cold rolling process work hardens the metal, increasing shelf strength and rigidity.
  • Low tooling cost – Roller dies are relatively inexpensive to produce compared to stamping or press brake dies.
  • Safety – Advanced roll forming lines have safety guards and sensors built in for operator protection.
  • Automation – Roll forming allows a lights-out, unattended production process once settings are optimized.

Overall, using a shelf panel roll forming machine improves productivity and quality compared to traditional fabrication techniques. The automated process, flexibility, and cost efficiency make roll forming the preferred method for high volume shelf production.

Roll Forming Machine Setup Considerations

Here are some important factors to consider when setting up a roll forming system for shelf manufacturing:

  • Product design – The shelf profile drawing is used to design the roller dies to progressively form the correct shape.
  • Material type – Common coil materials used are low carbon steel, stainless steel or aluminum. Material thickness is generally 16 to 14 gauge.
  • Coil width – Narrower coils around 24” to 30” help maximize yield of shelf panels and minimize scrap.
  • Die configuration – Roller dies must be set up in the proper bending sequence to avoid cracking and wrinkling.
  • Shearing method – Shear selection depends on metal thickness. Thicker materials may require an initial rotary shear.
  • Punch and notch tools – These stations must match the hole sizes and notch locations on the shelf design.
  • लाइन की गति – Roll forming speed is optimized based on metal type and thickness to avoid quality issues.
  • Conveyor sizing – Conveyors must be wide enough for the formed shelf panels which increase in width.
  • Safety codes – The line needs to incorporate guards, shields and sensors to meet safety guidelines.

With attention to these parameters, a shelf panel roll forming system can be configured for efficient production runs with quick changeovers between different shelf dimensions.
