  • Invalid Configuration

Easily-configured Posi-Bend™ Rotary Bender units are engineered to be less complex and less costly than wipe tooling. Rotary bending provides more consistent metal forming without wasting material on tests and regrinds.

• Lowers tooling costs
• Reduces setup time
• Produces bends over 90°
• Bends UHS steel
• Eliminates cam tooling to produce over bends
• Flexible and interchangeable
• Reduces down time
• Requires lower tonnage than traditional wipe tooling

The self-contained rotary bender gently rolls the material without unwanted distortion, sliding, or marring.


 

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.
