Din 6935 Standard Pdf • Best

Published by the Deutsches Institut für Normung (DIN), this standard specifies the for bent workpieces made from flat rolled steel. Unlike general geometric tolerances (e.g., ISO 2768), DIN 6935 focuses exclusively on the unique behaviors of bending—such as springback, elongation, and thinning of material at the bend radius.

) ratio up to 5; beyond this, the factor is typically set to : For opening angles over 65∘65 raised to the composed with power

Note: Ensure you are using the updated 2011-10 version, although many principles from older 1975 versions remain similar. Summary Table: DIN 6935 Key Factors Description Importance Flat rolled steel, strips, plates Defines application scope. Direction Transverse to rolling Minimizes cracking risk. Radius (R) Minimum bending radius Prevents fracture. k-Factor Correction value k Determines exact blank length. Goal Accurate developments Eliminates trial-and-error bending. Din 6935 Standard Pdf

Using the DIN 6935 standard provides several benefits for manufacturers, designers, and users of spring washers, including:

The German Institute for Standardization (DIN) published DIN 6935 to establish a uniform standard for the cold bending of flat steel products. It is a technical revision of the previous 2010-01 edition, primarily updated with the latest normative references. This regulation is designed to provide clear specifications and uniform technical bases for design, manufacturing, and inspection in steel construction and mechanical engineering.

The DIN 6935 standard covers several key aspects of spring washer design and manufacturing, including:

accounts for the relocation of the neutral axis. The standard calculation for the arc length of the shifted neutral axis ( ) uses the formula:

Because sheet metal stretches on the outside of a bend and compresses on the inside, the length of the metal changes during the bending process. DIN 6935 provides the mathematical formulas and correction factors (specifically the "bending factor" or Biegefaktor ) required to calculate the precise . ) ratio up to 5; beyond this, the

) in the bend area typically decreases, often by approximately , depending on the material and the sharpness of the bend. 3. Compensation Value (
