The most important consideration when bending metal on a brake is the minimum bend radius. 31036 Istrana (Treviso) Italy Accurate numbers for Springback have been one of the more difficult values to predict due to a large number of variables involved: material type, inside bend radius and method of forming to name a few. It is the change in thickness between the original dimension and the dimension at the smallest measurement at the point of fracture caused by testing and is expressed as a percentage of decrease from the original measurement. Once that separation begins to occur the bend to bend variations in angle and dimension will increase, sometimes dramatically. OK, so I have a 1,5mm 1.4301. If the punch nose radius is sharp enough it can even pull the grains apart when bending perpendicular to the grain. Please leave a comment on the calculator; what you thought about it, along with suggestions on how we might improve it.

The bend allowance describes the length of the neutral axis between the bend lines, or in other words, the arc length of the bend. This free chart outlines what bend radii is required for the approximate thickness of aluminum. Specifing a bend radius from here will help prevent hair line cracks. It simply processes these variables through the equations we will discuss below. Calculate the tonnage required to complete a 90° bend with a hydraulic press brake. In this case, the minimum producible inside bend radius is 63 percent of that 0.250-in. Due to this elastic recovery, it is necessary to over-bend the sheet a precise amount to acheive the desired bend radius and bend angle. We are going to review three bending scenarios with three different bending angles; 60, 90 and 120, and we will calculate K-Factor, Bend Allowance and Bend Deduction for them. In this case, you will need to find: Material Tensile Strength in psi.Material Thickness in inchesArea of Reduction as a decimal percentageOptional Die Opening in inches, Try our Springback Calculator and our Sharp Bend Indicator. Note that this is just a rule of thumb. material thickness, or 0.1575 in. Minimum Bend Radius Calculation Example. Sheet Metal Bend Radii If these guidelines are not followed, more research and/or, some form of analysis may be requried. It is normally expressed in terms of multiples of the material thickness, e.g. Move down to the desired bend angle and read the adjustment (gain). The tool can calculate the required bending force for bending aluminum, stainless steel, mild steel, and Weldox® or Strenx® high-strength steels.

JAVASCRIPT IS DISABLED. It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart. Material to the inside of this line ought to compress whereas the material on the outside of it should expand. When it comes to curved steel, finding the precise measurements is a challenging undertaking. A Sharp bend will always be less than a Minimum bend radius but, a Minimum Bend radius does not need to be sharp. The bending tool has a radius of 30 mm which means that our Inside Bend Radius (R) is 30 mm. Cells on the right will output the desired values.
