Electromechanical bending machine with 3 asymmetrical rolls:

The bending machines with 3 asymmetrical rolls enable the bending with total pre-bending, but the asymmetrical disposition of the rolls requires the overturning of the metal sheet. These bending machines fully replace bending machines with 3 pyramidal rolls. The array includes the light A series and the A series.

Light A series

These bending machines enable the bending of metal sheets whose thickness goes from 1 to 3,5 mm and whose useful length goes from 500 to 2000 mm.
The pinching of the sheet metal between the lower roll and the top roll is carried out through the use of a manual lever.
Raising and lowering of the side roll are controlled by hand through the use of a hand-wheel. The position of the side roll determines the bending radius.
The rotation of the two central rolls is motorized and controlled through a foot-pedal control, while the side roll is idler.
The 3 rolls are equipped with grooves that can bend flanged metal sheets and iron bars.
The side roll can be tilted by means of a toothed coupling, this allows the formation of conical pieces thanks to a specific tool.
In order to extract the final piece, the top roll can be released and opened horizontally.

The basic machine can be equipped with:

  • Induction hardened rolls.
  • Cone bending device.
  • Extended rolls for outside fitting of section bending rolls.
  • Section bending rolls.
  • Motorized third roll.
  • Raising and lowering of the side roll trough worm reduction gears.
  • Digital display for the bending roller.

A series

seriea

These bending machines enable the bending of metal sheets whose thickness goes from 1 to 9 mm and whose useful length goes from 1000 to 3000 mm.
The pinching of the sheet metal between the lower roll and the top roll is carried out by hand through the use of a hand-wheel.
Raising and lowering of the side roll are motorized and controlled from a control panel. The position of the side roll determines the bending radius.
The rotation of the two central rolls is motorized and controlled from the control panel, while the side roll is idler.
The side roll can be tilted by means of a toothed coupling, this allows the formation of conical pieces thanks to a specific tool.
In order to extract the final piece, the top roll can be released and opened horizontally.

The basic machine can be equipped with:

  • Induction hardened rolls.
  • Cone bending device.
  • Extended rolls for outside fitting of section bending rolls.
  • Section bending rolls.
  • Motorized third roll.
  • Powered raising and lower roller.
  • Digital display for the bending roller.
  • Digital display for the lower roller.
