How to calculate air bending force
F: bending force, N
Rm: tensile strength of material, N/mm²
T: bending sheet thickness, mm
V: lower die Vee opening, mm
L: bending sheet length, mm
The selection rule of lower die Vee opening
The lower die opening is the width of the lower die channel of the bending machine die, which is generally related to the material thickness. According to the data summarized by the market requirements, when the plate thickness range is within 0~3 mm, the lower die channel width V of the bending machine is equal to the plate thickness*6, for the precision bending, it can be narrowed to 4 times the plate thickness; when the thickness range is within 3~8mm, bending machine lower die channel width V is equal to the plate thickness*8; For plate thickness is over 10mm, the width of the V opening for the lower die is equal to the plate thickness*12.
| Plate thickness(mm) | 0.5~2.5 | 3.0~8.0 | 9.0~10.0 | over 12.0 |
| Notch width(mm) | 6*t | 8*t | 10*t | 12*t |
