Bending Force Chart
The capacity of Press Brake is generally defined in tons. Followings contained the details of load calculation in different types of bending methods like Air Bending, Formind etc. These are certain special applications like piercing, straightening etc, which also be used on press brakes. But these processes need special tools & differet load calculations.
Air Bending is the most widely used applications on press brake, Air Bending is done on three contact lines, two die edge & cone punch edge, The calculations for air bending as per following.
| T Sheet Thickness in MM | 0.5mm - 8 mm | 9 mm - 10 mm | 12 mm or more |
| V - Die Opening | 8T | 10T | 12T |
In Bottom Bending the upper & lower dies are usually made with an include angle of 90° to ensure sharp corners on the formed part in the forming process, the dies strike solidly & squeeze the material at stroke bottom. This process requires 3 - 5 time the tonnage needed in air bending. Since more tonnage is required bottoming is seldom performed on steel greater than 12 gauge. The adjustable “V” die opening for bottoming are : V=5 to 6x material thickness.
The basic factors to be considered while selecting a press brake, or calculating the correct setting for operation are :
| Parameters | Unit |
| Plate Thickness (t) | mm |
| Ultimate Tensile Strength Of Plate (s) | Kg/mm² |
| Aluminium | 25 Kg/mm² |
| Mild Steel | 45 Kg/mm² |
| Stainless Steel | 72 Kg/mm² |
| Bending Length (L) | mm |
| Die Opening (V) | mm |
| Minimum Internal Radius | mm |
| Minimum Flange (H) | mm |
| Bending Correction Force (K) | 1.3 |
| Required Tonnage (P) | M. Tones |
Load, P (Metric Tones) = K x L x S x t / 1000 x V
P=1.3 (K) x 3000mm (L) x 45 (S) x 3.15² / 1000 (24 mm) = 72 Metric Tones
P=1.3(K) x 3000mm (L) x 45 (S) x 3.15² / 1000 (24 mm) = 115 Metric Tones
The bending chart also gives the bend radius & minimum bend edge also. The bending chart defines the load required per mm thickness per meter. To use bending chart, select the “V” opening from upper most line & thickness from vertical line, the matrix shows the total load in tons per meter. To achieve total load, this valve should be multiplied by the total length of job.
