tonnage chart showing tons needed to punch a hole
Mar 09, 2016 · F = Punch force in tons. P = Perimeter of the stamped shape in inches. t = Thickness in inches. S = Shear strength of material. f = Factor between 0.5 and 0.95 when using punches with shear. Note that punch-to-die clearance, staggered punch lengths, and angular punch faces do not affect the overall total load requirement. C-Frame Punching Units & Tooling UniPunch ProductsHow UniPunch Speed Helps You:Faster Production Speed More holes in more parts per hour. If youre finishing 400 parts in a day now, imagine 2,400 instead.; Faster Into Production We can provide most UniPunch tooling within days, so theres no need for you to wait months.; Faster Setup Time Faster changeover from part to part.
Choose your die style and use the die clearance calculator on the page to determine the clearance you need. How many holes can I punch from one punch and die? When using the proper clearance between punch and die and ensuring that your machine has enough tonnage for the application, you should get approximately 1,500 holes from one punch. The die usually can last longer. If you are not getting this many holes out of your punch Conway Press - Hole Punch Tonnage CalculatorHole Perimeter= 2.5". Material Type= Steel-Mild. Material Thickness(in) = 0.125. Tonnage= 7.813 tons. This information is valuable when determining which of the Conway Press C-Series hydraulic presses will best suit your needs. Additional information regarding the differences about the C-Series modelsis available on the C-Series product page. Greenerd :Formulas and DataPunching - A quick guide to determine tonnage requirements for punching steel is:Diameter x thickness x 80 = tons (where 80 is constant for steel. Use 65 for brass.) Example:A 3" hole in .250" stock:3" x .250" x 80 = 60 tons. For noncircular holes, instead of
For accurate punching of inner and outer holes, these sets come with pilots that attach to the outer hole punch. Hammer-Driven Hole Punch Sets Use these one-piece tools to make round holes up to How to Calculate Punching Force (Formula & Tonnage Punch Force (KN) = 80 x 3 x 0.3447 = 82.728 KN Convert into tonnage:82.728 KN ÷ 9.81 = 8.43 Ton. For more details about the shearing strength including how to calculate it, you can refer to the answer from Wikipedia. Punching Force Calculator Hydraulic Press tonnage calculationPunching - A quick guide to determine tonnage requirements for punching steel is:Diameter x thickness x 80 = tons (where 80 is constant for steel.

Please review with your local CINCINNATI Sales Engineer when using calculator to size a new machine. The tonnage calculator is for 20ga to 3" material, bent over a vee die in the range of 5 to 19 times the material thickness. For applications outside of this range, please consult your local CINCINNATI Sales Engineer. Press Brake Tonnage Chart from American Machine ToolsAnswer:Use a 2-1/2 inch wide bottom die. 11.5 tons/foot x 10 feet = 115 tons. Question:How many tons is required for a brake press machine to bend 10 feet of 1/4 inch thick stainless steel using using a 2 1/2 inch wide bottom die? Answer:115 tons x 90ksi divided by 60ksi = 177.5 tons.
Tonnage:Use the following formula to calculate the tonnage required to punch a round hole in mild steel:Punch diameter x Material Thickness x 80 = Tons of pressure required. Example:to punch a 1/2" hole through 1/4" thick mild steel. 0.500 x 0.250 x 80 = 10 tons required. Use the following formula to calculate the approximate tonnage required to punch a shaped hole in mild steel:1/3 Perimeter of punch x Material Thickness x 80 = Tons Metric Hole Punch Tonnage Chart - freetechnicalchartsThis chart calculates the metric tonnage to punch a round metal hole. These charts are to be used as a guide only as the Inronworker or punch press tonnage calculations are approximate and depend on may variables. The rule to follow is never punch a hole diameter that is less than the material thickness. The metric hole punch tonnage chart is similar to the imperical punch chart on this site.
