As explained in my first post the bend deduction can be calculated using the following equation.

Bending force formula for sheet metal.

1 bending force for v bending see fig. Bend line shift bls the distance from the outside mold line to the original bend line on the flat pattern this is used to calculate the backstop location when working off of a flat pattern. The tensile strength of ordinary materials σb 450n mm2 which can be substituted into formula 2 to obtain. Advantages of bottoming include greater accuracy and less springback.

Punch edge radius in. 1 the bending force for v bending is obtained using the following equation. Die edge radius in. Round up to the nearest v opening on the chart to match to your tooling.

New bending force calculation method. Get to know them better to learn advance concept easily. If the width to thickness ratio v s is not equal to 9 and the diameter to width ratio is not equal to 0 16 the above calculator will no longer be applicable. The bending force can be calculated from the sheet thickness die opening bend length and the ultimate tensile strength of the material.

The die ratio may be entered to calculate the die opening which is typically 6 to 18 times the sheet thickness. An extremely large force is required in bottom bending depending on the amount of bottoming. 3 carbon 45 kg mm. Where ossb is the outside setback.

Air bending one of the three types of bending for sheet metal where the outside mold line is not pressed against the die. Larger bend radii require about the same force for bottoming as they do for air bending however smaller radii require greater force up to five times as much than air bending. The size of that force is considered to be 5 to 10 times the free bending force. Air bend force chart a chart used to calculate the tonnage required for a bend based on thickness tooling and length.

Ultimate tensile strength psi. Calculate the ratio of the tensile strength of your material to the standard steel. The following bending force calculator should be used. Ossb is defined as illustrated in figure 5 for different bending angles and can be calculated using the equation below.

The bending force calculation formula obtained here is very consistent with the data on foreign brochures. The bending radius must be at least 0 8 t to 2 t for sheet steel. Where a is the bending angle t is the sheet thickness and r is the bending radius.
