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.

It only becomes critical if a metal sheet is to be bent with precisely its minimum bending radius, as the spring back means that the bending radius must be smaller than the minimum bending radius. For this reason the actual minimum bending radius must always be larger than the theoretical possible radius. Bend Calculator found in: Bend-Tech EZ Tube Bending Software, Bend-Tech PRO Tube Bending Software, Complete Set of Bend Protractors, 5 inch Radius Bend Protractor, Wixey WR410 Digital Protractor, 6 inch Radius Bend Protractor,.. It only becomes critical if a metal sheet is to be bent with precisely its minimum bending radius, as the spring back means that the bending radius must be smaller than the minimum bending radius. For this reason the actual minimum bending radius must always be larger than the theoretical possible radius. Sheet Metal Mechanic (Free; Google Play 5 out of 5 stars) “Sheet Metal Mechanic (SMM) is a quick and easy reference for calculating bend deduction for an accurate sheet metal bend. SMM utilizes metal thickness, inside radius, and angle in degree to determine bend deduction.

Sheet Metal Mechanic (Free; Google Play 5 out of 5 stars) “Sheet Metal Mechanic (SMM) is a quick and easy reference for calculating bend deduction for an accurate sheet metal bend. SMM utilizes metal thickness, inside radius, and angle in degree to determine bend deduction. Sheet metal bending should be as perpendicular as possible to the direction of the metal fiber. When the sheet metal bend is parallel to the direction of the fiber of the metal material, cracks are likely to occur at the bend of the sheet metal, and the bending strength is low and it is easy to break, as shown in the following figure.
