The Tonnage Formula is the pressure required in tons to cut a blank or contour using a flat faced punch with no shear. In this example, the projected area 36 square inch multiplied by 5 Tons per square inch (36 X 5) results in 180 tons. DISCLAIMER: Actual bending force is affected by many factors such as friction between the material and the die, material thickness, material strength variations, rolling direction of the steel, work hardening and other parameters. This method will be much easier for you since you will not have to perform any calculations yourself. 12. By the press brake tonnage chart; By the bending force calculation formula; By the press brake tonnage calculator; Only after the tonnage of the press brake confirmed, then you can spend your time taking other factors (press brake components, toolings, controllers, etc) into consideration before making your decision to purchase the press brake. How to Obtain Tonnage Required for Punching Round Holes. Clamping force refers to the force applied to a mold by the clamping unit of an injection molding machine.

In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log 10 V. The measurement is used in assessing harbour dues and canal transit dues for merchant ships. If you punch round holes or square holes, or some other forms of holes through a given thickness of metal, you just want to know the force required to punch a hole in steel.. You can calculate the punching tonnage been required with the help of the following punching force calculation formula (blanking force formula):
