Start Position

Downward pressure of the press clamps the part with the rocker’s bending lobes before the bending action starts.

Bend

The rocker’s rotation forms the material around the anvil with less pressure and material distortion/marring than wipe tooling.

Posi-Bend Bend

Overbend by 3°

The bending action continues to form the material around the anvil until desired angle is completed. The anvil should have 5° relief to allow for the 3° overbend.

(The 3° overbend applies to cold rolled steel only.)

Posi-Bend Overbend

Material Springback

The rocker bends past 90° to compensate for material springback, leaving a 90° bent part (± 1/2°).


An internal spring returns the rocker position without scraping the material like wipe tooling.
