While DIN 6935 is prevalent in Europe, other standards exist.
The DIN 6935 standard emphasizes several critical factors to ensure successful cold bending: 1. The Importance of Rolling Direction
In summary, DIN 6935 is the essential technical manual for anyone involved in designing or manufacturing bent steel components, ensuring that finished parts meet stringent quality and safety requirements. If you are working on a specific engineering
It ensures consistency, quality, and uniformity in bent steel components used in structural engineering and general mechanical engineering.
The most common task for a designer referencing DIN 6935 is to find the correct bend radius. The standard dictates that the minimum permissible bending radius (r) depends on three primary factors: the sheet thickness (s), the steel grade, and the bending direction (transverse to the rolling direction is preferred as it offers better bendability). An extract from its tables gives you an idea of the data it provides:
The main standard is supported by two crucial supplements that provide deeper insight into precise calculations.
It emphasizes bending transverse (across) the rolling direction to prevent cracking and achieve higher quality. Bending Angles: Guidelines cover angles from 0° up to 180°. Minimum Bend Length: Recommends a minimum length of at least the bending radius ( ) to ensure consistent results. Modulus Metal Example Calculation Provide a for a specific material and thickness
: Lengths of the straight legs (measured to the theoretical sharp intersection point or the tangent point, depending on the chosen calculation variant).
Utilizing a globally recognized standard ensures that an engineering drawing created in one country can be accurately fabricated by a manufacturer in another.
: 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
