plate, but the principle is the same. Finally, add the tonnage required to lift the part: You can reduce the tonnage by using a larger die opening, but this will require you to take into account a larger inside bend radius and, therefore, a larger bend deduction and bend allowance for the flat-blank calculations. The material will need to be lifted during forming over a 1.125-in. If the material is 0.5 inch thick: 4 × 0.5 = 2. =. Finally, divide the bending force by 2,000 lbs. Troubleshoot quality issues in tube cutting. thick, grade 350 and 400 may have a minimum bend radius of 2.5 times the material thickness when transverse bending, while longitudinal bending may require a minimum bend radius that’s 3.75 times the material thickness (see Figure 1). A:You have the formula correct at 0.375 in. Danse avec les Stars. (1 U.S. ton), and you get the total additional tonnage required for lifting the part. Figure 2 You described a rough rule to find a steel’s minimum bend radius: Divide 50 by the material’s reduction percentage, as specified by the material supplier, subtract by 1, and then multiply by the plate thickness. For steel, aluminum, and stainless, you will find a variety of minimum bend radii-to-thickness ratios, and you will need to research these values in data provided by your material supplier. grain, increases the required minimum inside radius of the bend. Going back to the original question, you can see what would happen if you tried to form 0.5-in.-thick material in a die opening that’s only five times the material thickness. die opening. radius is the minimum producible inside radius for this material and not the recommended inside radius that you see on the bend allowance chart. allowance charts provided by the press brake manufacturer. We would like to show you a description here but the site won’t allow us. Total weight (lbs.) If your die opening is less than 8 times the material thickness for sheet metal, or less than 10 to 12 times the material thickness for plate, you will see a dramatic increase in the amount of pressure required to bend the material. Figure 3 Retrouvez tous les replay et vidéos de 50' inside, les interviews exclusives des stars, les news people et photos de 50' inside, un magazine présenté par Nikos Aliagas en exclusivité sur MYTF1. The recommended inside bend radius is what’s optimal in a typical application. Also, lifting the workpiece during forming can increase the tonnage required dramatically. 50 years ago it was reckoned that only Brazil produced more world-class players per head of population than Scotland. Also note that this is not a bend deduction chart. Sign up and be the first to know about the latest industry news, products, and events! material; that’s technically sheet metal and a long way from 0.5-in. The radii from the bend allowance chart (see Figure 2) is based on 15 percent of the die opening and represent basically a one-to-one relationship between the material thickness and the inside radius when using the recommended die opening of 5 in. 50 MinInside. 2010s: Were the 2010s the Golden Age of metal fabricating? Next, subtract 1 from that answer: 5 – 1 = 4. The weight of 10-ga. carbon steel per square foot is 5.625 pounds, so for 10-ft.-wide material that extends out in front of the press by roughly 10 ft., the total weight of the sheet in front of the press is: Material length (ft.) × Material width (ft.) × Weight of steel per square foot (lbs.) The calculated 0.375-in. So in this case, the minimum inside bend radius is 2 times the material thickness.”. Longitudinal bending, or bending with the material Next, subtract 1 from that answer: 5 – 1 = 4. Assuming you have the tonnage and could force the material into a die opening only 2.5 in. Now, multiply that answer by the plate thickness. I, along with your press brake manufacturer, would not recommend using a smaller die opening, if for no other reason than to avoid damage to your press brake and tooling. This portion of a bend allowance chart gives the recommended inside radius, not the minimum inside radius that can The minimum inside bend radius is even larger when bending with the grain. Now, multiply that answer by the plate thickness. SHY'M chez Cauet. 2135 Point Blvd., Elgin, IL 60123 (815) 399-8700, Steve Benson is a member and former chair of the. To state your example, “If the steel has a tensile reduction value of 10 percent, divide 50 by that value: 50/10 = 5. Enjoy full access to the digital edition of The Additive Report to learn how to use additive manufacturing technology to increase operational efficiency and improve the bottom line. die is 10 times the material thickness, and, as a general rule at these thicknesses, 10 to 12 times the material thickness is correct and common. / Half of die opening width (in.) will require 69.86 tons to form and 22.50 tons to lift, for a total of 92.36 tons. Editor’s Note: This chart is for illustrative purposes only and should not replace bend Enjoy full access to the digital edition of STAMPING Journal, which serves the metal stamping market with the latest technology advancements, best practices, and industry news. Figure 1 Next, multiply the total weight by 60 (one-half of the sheet width in inches) and divide that by half the die opening width. It’s true that the harder and thicker the plate is, the greater the minimum bend radius. Q: In a previous Bending Basics article, you mention a “material’s tensile reduction percentage” used for calculating the minimum inside bend radius of various metals. If the material is 0.5 inch thick: 4 × 0.5 = 2. of bending force60,000 / 2,000 = 30 U.S. tons. Easily access valuable industry resources now with full access to the digital edition of The WELDER. But again, all this refers to the minimum inside bend radius—what’s physically possible if you have press brakes and tooling that can handle the high tonnage. SafanDarley R-Brake 130T – the flexible bending cell. However, for many reasons I wouldn’t recommend you do this. Fabricators & Manufacturers Association, Intl. For instance, a die opening of 1.25 in. The bend allowance is used to figure the bend deductions Les années de bonheur. will require 88.84 tons to form and 27.00 tons to lift, for a total of 115.84 tons. 12:00am, 120 min IPL 2016: RCB v Gujarat Lions . die and thereby producing that one-to-one inside radius-to-material-thickness ratio, you will achieve the best results in your product and the most stable bend angles. The 5-in. you need for the flat layout. However, I believe you misinterpreted the meaning and how it relates to your bend allowance chart.

CAP 48. By using the 5-in. Also note that all these are just examples; actual minimum radius values vary by grade. × Half of sheet width (in.) To state your example, “If the steel has a tensile reduction value of 10 percent, divide 50 by that value: 50/10 = 5. And this is just for 10-ga. material. Next, use this formula to calculate forming tonnage for mild steel (all variables are in inches unless otherwise noted): [(575 × Material thickness2)/Die opening] × Bend length in feet = Forming tonnage, [575 × 0.1352/1.125] × 10 = 93.15 tons to bend. Easily access valuable industry resources now with full access to the digital edition of The Tube & Pipe Journal. Lifting the workpiece during forming can increase the tonnage required. Figure 3 shows 10-gauge (0.135-in.) So in this case, the minimum inside bend radius is … Easily access valuable industry resources now with full access to the digital edition of The FABRICATOR.

We would like to show you a description here but the site won’t allow us. wide—just five times the material thickness—you would achieve the minimum inside radius that’s possible in an air form. )(562.5 × 60) / 0.5625 = 60,000 lbs. Nonetheless, some folks do this if they have high-tonnage machines. be produced. To calculate the additional tonnage, you need the weight of steel per square foot for the given thickness, which you can get from your supplier or on gauge charts for common materials.
