Estimate bending force calculation formula is
- P: Estimate Hydraulic press Brake Bending force (T)
- S: Plate thickness (mm)
- L: Bending Length (m)
- V: Hydraulic Press Brake Bottom die V opening width (mm)
- The Hydraulic press brake machine bending force calculation is based on mild steel (tensile strength = 450Mpa). For other material, we shall time constant K (related with material tensile strength, hardness, elongation). for example, Stainless plate characters can be different according to plate number. we can set K=1.5.
- Normally V (hydraulic press brake machine bottom die V opening width) can be 6 ~12 times plate thickness. for thin plate we select smaller V opening. while for bigger and Harder plate, we shall set bigger V opening. Bigger V will introduce bigger bending radius.
