(the "unfolded" length of a part). Key Technical Insights
For decades, has been the definitive German technical standard used globally to regulate these calculations. It provides the mathematical formulas and correction factors required to determine flat blank lengths accurately. What is the DIN 6935 Standard?
. It is widely used in steel construction and mechanical engineering to determine minimum bending radii, calculate the "developed length" (the flat length of metal needed before bending), and establish permissible deviations. Core Technical Specifications
When sheet metal is bent, the material on the outside of the bend stretches, while the material on the inside compresses. Somewhere between these two surfaces lies the , which experiences no change in length. DIN 6935 defines how to locate this neutral axis using a correction factor ( Din 6935 Standard Pdf
Mastering Cold Bending: A Deep Dive into the DIN 6935 Standard
For professional application, you can view technical summaries or find the full DIN 6935 Standard PDF on platforms like Modulus Metal ANSI Webstore for a particular bending angle? DIN 6935 Cold Bending Guidelines | PDF - Scribd
= The compensation value (often referred to as the bend compensation or correction factor) 2. Calculating the Compensation Value ( According to DIN 6935, the correction factor (the "unfolded" length of a part)
The standard provides minimum radius values to prevent cracks or material fracturing, often relating the radius to the material thickness (
The standard outlines the mechanical properties of the steel strips, including their yield strength, tensile strength, and elongation. These properties are essential in determining the steel strips' ability to withstand various types of loading, such as bending, stretching, and impact. The standard also specifies the testing methods and conditions for determining these mechanical properties.
: For best results, bending should ideally be performed transverse (perpendicular) to the rolling direction of the steel to avoid structural failure. Calculating Developed Length One of the primary uses of DIN 6935 is calculating the stretched length What is the DIN 6935 Standard
= Lengths of the straight legs (measured to the theoretical sharp intersection point or vertex)
When you bend a piece of sheet metal, the outside of the bend stretches, and the inside compresses. The neutral axis (where no stretching or compression occurs) shifts inward. DIN 6935 provides a scientifically validated method to locate that neutral axis using the .
As of 2025, the current active version is DIN 6935:2017-01 (published January 2017).
Inventor utilizes Sheet Metal Unfold Rules. You can set the Unfold Method to , which automatically overrides default linear approximations with the standard's radius-to-thickness ratio formulas. Downloading a DIN 6935 Standard PDF
