The standard outlines several parameters essential for precise sheet metal fabrication: Bending Radius (

Developed Length=a+b+vDeveloped Length equals a plus b plus v are the leg lengths, and is a . Opening Angle ( Compensating Value ( 0∘0 raised to the composed with power 90∘90 raised to the composed with power

): Recommends specific radii from the DIN 250 series (e.g., 1, 1.2, 1.6, 2, 2.5 mm) to ensure uniform curves across different machinery. Din 6935 Standard Pdf

) decrease of approximately in the rounded portion of the bend.

Bending should ideally be carried out transverse (perpendicular) to the rolling direction of the steel to reduce the risk of cracking. Calculation of Developed Lengths Din 6935 Standard Pdf

Calculated using a specific formula involving radius, thickness, and a correction factor ( 90∘90 raised to the composed with power 165∘165 raised to the composed with power

The core utility of the DIN 6935 standard is its method for determining the unfolded length of a part using the formula: Din 6935 Standard Pdf

For mechanical bending, the standard suggests a minimum leg length ( ) of approximately 4 times the bending radius ( ) to prevent defects. Thickness Reduction: It accounts for a material thickness (

The is a critical technical guideline for the cold bending of flat rolled steel products. Primarily used in mechanical engineering and steel construction, it provides the standardized formulas and tables required to calculate "developed lengths"—the length of a flat sheet before it is bent into its final shape.
