10 Bending help There are two different ways of bending: Air bending Bottoming/coining The force/pressure F for bottoming/coining is 3 up to 8 times higher than for air bending. The die opening V should be 6 up to 12 times of the material thickness t. It also dictates the force/pressure F needed for air bending. For the choice of the opening V must be considered also the shortest flange b and the angle α. With a smaller die opening V the inside radius r i will be smaller. With the below shown table of force and the formulas you can calculate the appropriate values. Bottoming/coining Air bending t Material thickness F Force/pressure V Die opening b Shortest flange r i Inside radius R m Resistance α Angle Table of force: needed force for 90 air bending, resistance R m = 450 N/mm 2 t (mm) V (mm) 2,9 4,3 5 5,7 7,1 8,5 9,9 11,4 12,8 14,2 17,7 22,7 28,3 35,4 44,6 56,6 70,8 88,4 113,2 b (mm) 0,7 1 1,1 1,3 1,6 1,9 2,2 2,5 2,9 3, ,3 7,9 9,9 12,5 15,7 19,6 25 r i (mm) 0, , , , , F in kn/m 870 Example: t = 2,0 mm Optimum die opening V: Shortest flange b: Inside radius r i : Needed force/pressure F: 12 mm 8,5 mm 1,9 mm 250 kn/m Resistance Aluminium R m = N/mm 2 Mild steel R m = N/mm 2 Stainless steel R m = N/mm 2 Calculation of the optimum die opening V (in mm) Material thickness t 0,5 2,5 3,0 8,0 9,0 10,0 12,0 and more Die opening V 6 x t 8 x t 10 x t 12 x t Calculation of the shortest flange b (in mm) Angle α Flange b 0,51 x V 0,55 x V 0,58 x V 0,71 x V 1 x V 1,31 x V 1,94 x V Calculation of the force/ pressure F (in kn/m) F= R m x t 2 x (1+ 4 x t ) V V Calculation of the inside radius r i (in mm) r 5 x V i = 32 Scaled, rusted or not oiled up sheet metal will cause a much higher force.
