The robotic roller hemming system consists of a standard industrial robot integrated with a roller hemming head, offering a very flexible solution. The roller hemming head consists of a central body, with guides and rollers that are designed according to the geometry of the car component.

In principle, it is a simpler and more economic system than tabletop hemming, offering a higher degree of flexibility. The roller hemming technology can be used both for steel and aluminium parts.

If the flange angle is wider than 105°, a pre-roller hemming system is necessary.

Roller Pre-Hemming Station

  • Flange bending from 145° to 105°
  • Maximum passes for pre-hemming operation: 2
  • Maximum speed for linear hemming section: 700 mm/sec
  • Medium speed: 300 mm/sec
  • Maximum load: 200 Kg /linear cm
  • Number of rollers on hemming head: 5

Roller hemming station

  • Move flanges of closures parts from 105° to 0°
  • Tool working perpendicular to flange, to use the robot axis in the best way
  • Minimum passes for hemming operation: 3, therefore:
    from 105° to 60°
    from 60° to 30°
    from 30° to 0°
  • Maximum speed for linear hemming section: 700 mm/sec
  • Medium speed 350 mm/sec
  • Maximum load 200 Kg /linear cm
  • Number of rollers on hemming head: 5
