based on the thickness-to-radius ratio (R/s). Graphical representation of bend lines and positions. Dimensioning and Calculation Examples . Benefits of Following DIN 6935

Understanding the DIN 6935 Standard for Sheet Metal Bending The is a crucial technical regulation developed by the German Institute for Standardization (Deutsches Institut für Normung). It establishes the mathematical foundations and calculation methods for determining the flat layout (blank length) of bent sheet metal parts.

is a German Institute for Standardization (Deutsches Institut für Normung) document that outlines the guidelines for the cold bending of flat-rolled steel. It covers the methodology for calculating the "developed length" (or "flat pattern") of a piece of metal, taking into account the stretching of the material during the bending process. Key Aspects Covered by DIN 6935 Bend Radius ( ): The inside radius of the bend. Bending Angle ( ): The angle of the bend, which can range from 0∘0 raised to the composed with power 180∘180 raised to the composed with power Material Thickness ( ): The thickness of the sheet metal.

-factor) to calculate the precise unfolded length of the initial flat sheet. 2. Core Mathematical Formulas To calculate the total unfolded length (

It is crucial to use the most current version of a standard for legal and technical compliance. The current revision is . This version supersedes and replaces several earlier editions: Din 6935 Standard Pdf

Where v is the (often represented as a reduction in length due to deformation). 2. Correction Factor k (K-Factor)

The standard provides a mathematical framework to calculate the flat blank length (

When sheet metal is bent, the outer surface stretches and the inner surface compresses. To ensure the final part has the correct dimensions, designers must calculate a compensation value that accounts for these material changes. Key Specifications Bending Radius:

It defines how to calculate the unfolded length by summing the linear leg lengths and subtracting compensation values ( Rolling Direction: based on the thickness-to-radius ratio (R/s)

DIN 6935 is a technical standard developed by the German Institute for Standardization ( Deutsches Institut für Normung ). It provides the mathematical foundations and empirical factors needed to calculate the blank length of flat steel products before they undergo cold bending.

: Explains how to determine the "stretched" or "unfolded" length of a part by using compensation values ( ) and correction factors ( Neutral Fiber Deviations

DIN 6935 is the primary German technical standard for the . It is widely used in steel construction and mechanical engineering to determine minimum bending radii, calculate the "developed length" (flat length) of parts before they are bent, and define permissible tolerances. 1. Key Technical Specifications

is the distance from the inside of the bend to the neutral axis). Benefits of Following DIN 6935 Understanding the DIN

Standards are living documents. Although a draft revision was proposed and later withdrawn, DIN 6935 will continue to evolve to reflect current industrial practices. The community of users, professional associations, and the NAFS committee will continue to provide feedback and drive the standard's development.

To achieve seamless integration between design and manufacturing using the standard, follow these steps:
