You will need to know your Material Thickness (MT), the Bend Angle (B<), the Inside Radius (IR), and the K-Factor (K). The other types of bending listed use specially designed tools or machines to perform the work. Rotary bending is similar to wiping but the top die is made of a freely rotating cylinder with the final formed shape cut into it and a matching bottom die. Table 1 provides a general guide on cable multipliers for various cable types. Three-point bending is a newer process that uses a die with an adjustable-height bottom tool, moved by a servo motor. View our © 1997 - 2020. A die with a long rail form tool with a radiused tip that locates the inside profile of the bend is called a punch. There should be proper pre-punching allowance. The bending tool has a radius of 30 mm which means that our Inside Bend Radius (R) is 30 mm. Both bend deduction and bend allowance represent the difference between the neutral line or unbent There is sheet metal software available, that performs all calculations automatically, like SolidWorks and LITIO.The BA can be estimated using the following formula, which incorporates the empirical K-factor:The bend deduction BD is defined as the difference between the sum of the flange lengths (from the edge to the apex) and the initial flat length. The Bend Allowance Formula takes into account the geometries of bending and the properties of your metal to determine the Bend Allowance. All Rights Reserved by Javelin Technologies Inc.Saeed Mojarad is an application engineer at Javelin Technologies. The thickness of pipe, flexibility of the material, angle of bend needed and other factors are all considered. While coining can attain high precision, higher costs mean that it is not often used. He received his B.S from Mazandaran University, Iran; and his M.S. On contact with the sheet, the roll contacts on two points and it rotates as the forming process bends the sheet. The bend beam can move the sheet up or down, permitting the fabricating of parts with positive and negative bend angles. With coining and bottom bending, the punch nose radius establishes the inside bend radius value to be inserted into the formulas for the bend deduction. It provides a non-marring bend and is suitable for pre-painted or sensitive materials. In this formula the initial length is 300 mm. By replacing Initial Length, Leg Length 1 and 2 in the above equation we can calculate the Bend Allowance as follows:We know that BA is the length of the arc on the neutral axis. Adjustments between the ram and the upper tool are made using a hydraulic cushion, which accommodates deviations in sheet thickness. Though faster than folding, wiping has a higher risk of producing scratches or otherwise damaging the sheet, because the tool is moving over the sheet surface. This bending method is typically considered a "non-marking" forming process suitable to pre-painted or easily marred surfaces. In this method, the bottom V-die is replaced by a flat pad of urethane or rubber. The arc length of the neutral line is the length of the sheet metal you have to leave for the bend. Quality problems associated with this method are countered by angle-measuring systems, clamps and crowning systems adjustable along the x and y axes, and wear-resistant tools.The K-factor approximations given below are more likely to be accurate for air bending than the other types of bending due to the lower forces involved in the forming process.

The beam rises and folds the sheet around a bend profile.
