Semi-automatic ceiling fan blade riveting machine

The operator loads the shank, washers and blade. The machine feeds and presses the rivets and delivers the finished blade to a conveyor. Consistent riveting at a lower investment, for fan plants not yet running the volume for full automation. Three machines are in production at fan manufacturers.

The operator loads, the machine rivets

When shanks are riveted to blades by hand, joint quality depends on the person at the press. This machine keeps the operator for loading only. Rivet feeding, insertion, pressing and unloading are automatic, so every joint is made the same way, cycle after cycle.

  1. 01
    Consistent joints

    Rivets are fed, inserted and pressed by the machine, with a hydro-pneumatic cylinder setting every rivet.

  2. 02
    One machine for every model

    It runs the full range of blades and shanks in your plant. Switching between models with the same CD costs no production time at all.

  3. 03
    Changeover in about 15 minutes

    When the CD changes, only the fixture and press assembly are swapped. No skilled fitter is needed, and nothing has to be realigned afterwards.

  4. 04
    Every step verified

    Each operation is closed loop. Laser, fibre-optic, photoelectric, proximity, reed and limit-switch sensors confirm every step before the next one begins.

Manual loading, automatic riveting

The fixtures travel on a rotary table, so the operator loads one fixture while the machine rivets and unloads the others.

  1. 01

    Loading

    The operator places the shank, washers and blade on the fixture.

  2. 02

    Transfer

    The rotary table carries the loaded fixture to the riveting station.

  3. 03

    Riveting

    Rivets are fed automatically, inserted into the assembly and pressed home by a hydro-pneumatic cylinder.

  4. 04

    Unloading

    A pneumatic two-axis unit lifts the finished blade and places it on the outgoing conveyor.

Built to your blade design

Choose the number of rivets and whether nylon washers are used. Every combination is available.
