2. Multi-purposed bending solution tool

Proposal of Wing bend tool

Short flange !

Tapered angle
bend deformation !

Very close bending
to the hole !

2. Potential issue for bending application！

Bending tool （standard die ）1) Holes close to the bend line deform and peel up.
This spoils the component and it will be rejected as scrap.
2) To avoid this, the component will be machined after bending. This
increases the production cost.
No chance for competition!
3) Mirror finish stainless steel is difficult to bend without leaving bending
line marks.
Marks cause the part to be scrapped.

Easier bending to avoid the marks, peeled-off holes
and the deformation is really demanded!

Improvement
proposal
The solution tooling for bending work dissatisfaction

By using Wing bend tool・・・
1) Work without bending line.
* NOTE） Protective vinyl sheet is required.

2) Shorter flange length.
3) No hole deformation.
4) No elongated angle bending.

Needed solutions by the customer
・No marking is allowed as finishedsurface.
・White coated vinyl would be cut bybending work.
Current process method
・Using very narrow V opening.
Stainless 2.0mm thickV12（appropriate）

V10

・Covering with white protective vinyl sheet
One sheet is not good enough , so using two sheets of white vinyl
How the situation has been improved by Wing bend?
Model WB230
No cut for white vinyl sheet ( No marking remained)

WB230

Effectiveness・Cheaper blue color protective sheet can be used.
・Multiple different thickness sheet can be applied to one die.
This reduces the die set up time.
