Din 6935 Standard Pdf |work| 💯 Best Pick
The main purpose of this standard is to provide a standardized approach to calculating how much material stretches during the bending process, allowing manufacturers to determine the exact size of the sheet metal before it is bent. Key Concepts in DIN 6935 1. Bending Allowance and Deduction
: Provides formulas and compensation values (
The DIN 6935 standard is a critical specification in the engineering and manufacturing industries, providing detailed guidelines for the design, materials, and testing of spring washers and disc springs. Adhering to this standard ensures safety, performance, and compliance with regulatory requirements and industry standards.

When sheet metal is bent, the material on the outside of the bend stretches, while the material on the inside compresses. The —a line within the material that neither stretches nor compresses—shifts towards the inside of the bend. Stretched Length ( Lfcap L sub f ): The total length of the flat part before bending. Leg Lengths ( ): The dimensions of the sides of the bent part. Correction Value (
If you are working on a specific engineering project, let me know , thickness , or bend radius you are using, and I can help you calculate the exact flat length or k-factor values according to these rules. Share public link
): The value defined by DIN 6935 used to calculate the difference between the sum of the leg lengths and the actual flat length. 2. DIN 6935 Formula The main purpose of this standard is to
): The total length is typically calculated as the sum of the straight leg lengths plus a compensating value (
Subtract the deduction from the total nominal sum ( ) to get the exact layout length. Where to Find and Download the DIN 6935 Standard PDF

In the world of precision manufacturing and mechanical engineering, few things are as frustrating as designing a bent sheet metal part only to find that the flattened blank does not fit, the holes are misaligned, or the final dimensions are wrong. This discrepancy occurs due to a phenomenon known as the K-factor or bend allowance—the stretching of material on the outer radius of a bend.
: Explains how to determine the "stretched" or "unfolded" length of a part by using compensation values ( ) and correction factors ( Neutral Fiber Deviations
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
-factor represents the ratio of the distance of the neutral axis from the inner surface to the material thickness. If the bending radius -factor is used to calculate the correction value. Large Radius Rule: If the bending radius , the position of the neutral axis is considered to be at , meaning the -factor equals 1.
