If you need to implement these calculations for an upcoming production run, let me know: What and thickness ( ) you are using? What is your target internal bend radius ( ) ? What bending angles does your part require?
, you must move to the next higher value in the table to account for increased stress.
To ensure high-quality, defect-free bends, DIN 6935 offers several practical recommendations: Din 6935 Standard Pdf
Unlike general tolerance standards (like ISO 2768), DIN 6935 specifically addresses two critical aspects of sheet metal bending:
) and the specific grade of steel. For example, the radius must often be increased for bending angles exceeding 120∘120 raised to the composed with power to maintain material health.
: The , often referred to as the bend deduction. The Deduction Value ( : Visit your corporate standards portal today to
It specifies permissible radii based on material thickness and steel grade to prevent cracking and ensure structural integrity. Developed Length Calculation:
DIN 6935 is no longer valid for new designs. It has been replaced by ( Metallic materials — Sheet and strip — Determination of the plastic strain ratio ).
Mastering Cold Bending: A Deep Dive into the DIN 6935 Standard What bending angles does your part require
: Summary guides and tables of the standard's calculations are often available on professional platforms like or specialized engineering sites like Modulus Metal under this standard? DIN 6935: Cold Bending Steel Standards | PDF - Scribd
💡 : When selecting a bending radius, always refer to the "bolded" values in the Scribd DIN 6935 Tables first. These are the preferred industry standards that offer the best balance between structural integrity and ease of manufacturing.
It applies to sheets, plates, and strips made of steel.
: The standard acknowledges that the thickness of the material decreases by approximately 20% in the rounded portion of the bend. Evolutionary Context
The standard provides the mathematical framework and geometric rules for calculating the (unfolded length) of a part before it is bent. This ensures that once the metal is formed, its final dimensions remain accurate despite the physical stretching and compression that occur at the bend.
