Calculation formula for cnc press brake bending machine tonnage
In CNC cnc press brake bending machines, tonnage refers to the maximum pressure or bending force that the machine tool can apply. The calculation formula for tonnage can be determined based on different materials and plate thicknesses. The common formula for calculating the tonnage of a cnc press brake bending machine is as follows:
Tonnage=(material strength x plate thickness x bending length)/(plate bending factor x mold opening width)
Among them cnc press brake bending machine :
Material strength refers to the yield strength or tensile strength of the material to be bent.
Plate thickness refers to the thickness of the board to be bent.
The bending length refers to the distance at which pressure is applied to the sheet metal.
The bending factor of sheet metal refers to the bending performance of a material, which is generally searched or calculated based on the material’s bending performance table.
The width of the mold opening refers to the opening width of the upper and lower molds used to clamp the sheet metal.
It should be noted that the above formula is only a commonly used approximate calculation method, and the actual situation may vary depending on the specific equipment and material characteristics. In practical use, it is recommended to consult equipment manufacturers or professional engineers to obtain more accurate tonnage calculation results.
