τ = F/A . Ironworker Videos. 25/64 = 0.390625 Sharpening. Tooling Maintenance. Know thy steel for correct tonnage calculations: It is absolutely critical that the mechanical properties of the steel to be formed are understood correctly and used in any calculation or simulation that determines tooling tonnages. The actual tonnage may vary from this calculation due to several factors such as the friction of the material on the die, thickness variations of the material and actual tensile strength. 7/32 = 0.21875 17/64 = 0.265625 53/64 = 0.828125 Metal Gauges. 16 gauge = .0635" The result is then expressed in Btu per hour. The calculator accepts measurements in decimal format based on inches. 15/16 = 0.9375 13 gauge = .0934" 3/64 = 0.046875 Check the Tonnage. Maxium amount of shear will cut tonnage in half as long Example: using the cylinder calculation above and a 1,000 psi pump, multiply 19.625 by 1,000 to get 19,625 pounds of force. Then select your material on the right or fill in the tensile strength of the material you are using (KSI). Material 7/64 = 0.109375 There are some limitations that you should be The following form will help you calculate how much tonnage is needed to punch round holes through a given thickness of metal. can not exceed the diameter of the hole being punch. The calculation of the shear force of the shearing machine is a calculation formula inside the technical world. These shear tonnage requirements are used on machines like: Accurpress, Amada, Betenbender, Pacific, Standard and Piranha shear machines. 28 gauge = .0187" Select a shape below to calculate the punch tonnage required. Formula: TONNAGE IN MILD STEEL = 3.1416 X DIAMETER OF HOLE X MATERIAL THICKNESS X 25 Example: 3.1416 X 2.000 X .250 X 25 = 39.26 TONS To use our tonnage calculator select either the hole diameter or shear length option. It means that you can verify the max. 12 gauge = .1084" 61/64 = 0.953125 The formula used by this calculator to determine the piston cylinder force from pressure and diameter is: … 13/64 = 0.203125 17 gauge = .0575" 51/64 = 0.796875 Be sure to compare the rating of the machine, not only in tons, but also the diameter of the hole and thickness of material it can punch. 9/32 = 0.28125 All input 7/8 = 0.875 … 11/32 = 0.34375 Grinding cutting shear is done to create a scissorlike action between the punch and the die. 19/64 = 0.296875 11/16 = 0.6875 29 gauge = .0172" 23/64 = 0.359375 1. 45/64 = 0.703125 Standard Clearance Recommended Between Punch and Die, Typical Die Clearance for Punching Mild Steel, Required Tonnage for Punching Mild Steel with Tensile Strength of 50,000 PSI, How to Calculate Required Tonnage for Punching Mild Steel with Tensile Strength of 65,000 PSI, How to Calculate the Diagonal Dimension of a Punch, How to Calculate the Largest Square Size Allowed for a Punch Style, Required Tonnage for Punching Mild Steel with, How to Calculate Required Tonnage for Punching, How to Calculate the Largest Square Size Allowed.
