Special solutions

Radius bending (using air-bending tools)

Radius bending (using air-bending tools)

Considerations: -for mild steel and 3t<R<30t, R results will vary around ±5% -for R≥30t  less accuracy expected -for  B<10t  coining operation is recommended

Radien bending (using counterpressure)

Radien bending (using counterpressure)

Considerations: -for mild steel and R>30t, R results will vary around ±5% -for  B<10t  coining operation is recommended -depending on material, much higher bending force is needed

Radius bending (using coining tools)

Radius bending (using coining tools)

Considerations: -for mild steel and R<30t, R results vary around  ±5% -for  B≥ 10t  air bending operation is recommended -bending force could increase heavily, depending on material

Offset bending

Offset bending

Considerations: -best results for R≈ 0,3H;  B=1,4H+5mm;  H<12mm  (mild steel) -H results will vary around  ±0,2mm -smaller height values of H<2,8t are resulting less accuracy

Hat bending

Hat bending

Considerations: -best results for R1≈ t;  R2≈ 2t;  H≈(5t bis 15mm)  U≈(4t bis 30mm) -H and U results will vary around  ±0,2mm -smaller flange values of B<10t are resulting less accuracy

U bending

U bending

Considerations: -best results for R ≈ t;  U≈(4t bis 30mm) -U results will vary around  ±0,2mm -depending on material top side of the U shape could slightly open

Beading (longitudinal to the bending line)

Beading (longitudinal to the bending line)

Considerations: -best results for  R≈(3t bis 10mm);  V≈(4t bis 30mm)  and  A> 60° (mild steel) -H results will vary around  ±0,2mm -smaller flange values of B<10t  are resulting less accuracy

Beading (transversal to the bending line)

Beading (transversal to the bending line)

Flattening

Flattening

Considerations: -for  C=2t  bending force increases heavily -for more complex sheet parts double-deck tool type is not possible -flange of  H > B  could weaken tool tonnage
