Understanding the Bend Allowance and consequently the Bend Deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. As this happens you gain a small amount of total length in your part. Bending Radius There should have bending radius for sheet metal bending, bending radius should not be too large or too small, it should be chosen appropriately. If the bending radius is too small, it will cause cracking at the bend position; if the bending radius is too large, it is easy to rebound. L Bending. 1) Factors determining the minimum L bending. As the middle of the V groove is hollow, when forming, the edge fold must be longer than the hollow section and the specific landing edge size varies in the production of different companies (the lower section of V groove is under use for a long time, the R angle increases, which makes the scrap edge distance increases accordingly ... The bend allowance added to the flange lengths is equal to the total flat length of the part. The bend deduction, sometimes called the bend compensation, describes how much the outside of the sheet has been stretched. Therefore, the bend deduction equals the difference between the mold line lengths and the total flat length. Bending force = = 166.25 kN 29 Nageswara Rao Posinasetti February 6, 2012 Calculate the bending force required for a C50 steel 1.5 mm sheet of width 1 m to be bent in a wiping die. The die radius used is 3 mm. C50 steel, ultimate tensile strength can be taken as 800 MPa. 30 Nageswara Rao Posinasetti February 6, 2012 In sheet metal design, the K-factor is used to calculate how much sheet metal one needs to leave for the bend in order to achieve particular final dimensions, especially for between the straight sides next the bend. Use the known K-factor and the known inner bending radius to calculate the bending radius of the neutral line.
