Rotary bending units
ACCU-BendTM offers you an efficient alternative to conventional bending with a bending punch for use in follow-on composite and edging tools.
Product Features
The Accu-BendTM is manufactured with the same precise methods and processes you put into your own designs. The bending lobes of the Accu-BendTM are specifi cally treated to withstand the wear associated with a repetitive bending motion. The saddle is a low-friction alloy chosen for the ability to hold up to a bearing load with little to no wear.
Benefits at a glance:
- U bends and Z bends can be realized
- short-leg bends and bends with reinforcing ribs can be produced
- Ideal for bending high-tensile materials
- bending of stainless and painted steel
- bending of components with large sheet thickness
- Overbending of up to 120° possible in one step
- Angel tolerance of +/- 1/2° possible
- 40-80% reduction in forming force
- Reduction in tool imprint thanks to lower bending force
- easy adjustment in case of unsteady material properties
- holding-down clamp function integrated into roller bending units
- no holding-down plate required
- reduced number of bending steps
- since the formation of large bending angles is possible in one operation
- low-maintenance thanks to tribological pairing
- of hardened steel (bending shaft) on bronze using solid lubricant inserts (bearing bushing or retainer)

Costumer part
part during bending process
part after spring back
- spring back depends on Material, Bending radius, bending angle as well as forming speed
- required overbend can only be determined by bending tests or based on experienced data – Please contact Anchor Lamina
- Please note: “The higher the materials yield strength, the higher the spring back.” and “The higher the bending radius, the higher the spring back.”
- The radius at the anvil must be smaller then the radius of the finished part
Formula to calculate radius at anvil:
- r = (rc * Wc) / Ws
- r(c) = radius anvil
- W(c) = bending angle finished part
- W(s) = Bending angle in process
