What are the main features of Din 6935 Standard PDF?
Din 6935 Standard PDF is a comprehensive and detailed document that covers all the aspects of bending sheet metal. It provides the technical specifications and parameters that you need to know and use for bending sheet metal. Here are some of the main features of Din 6935 Standard PDF:
Bending radius
The bending radius is the distance from the center of the bend to the inner surface of the sheet metal. It determines how sharp or smooth the bend is. The bending radius depends on the material, thickness, and bending angle of the sheet metal. The smaller the bending radius, the sharper the bend. The larger the bending radius, the smoother the bend.
Din 6935 Standard PDF provides a formula for calculating the bending radius for sheet metal. The formula is:
R = (t + k) * r
Where:
R is the bending radius
t is the thickness of the sheet metal
k is the K-factor
r is the ratio of the bending radius to the thickness
Din 6935 Standard PDF also provides tables and charts that show the recommended values for r for different types of materials, thicknesses, and bending angles.
Bending angle
The bending angle is the angle between the two legs of the bent sheet metal. It determines how much the sheet metal is bent. The bending angle depends on the material, thickness, and bending radius of the sheet metal. The smaller the bending angle, the less the sheet metal is bent. The larger the bending angle, the more the sheet metal is bent.
Din 6935 Standard PDF provides a formula for calculating the bending angle for sheet metal. The formula is:
α = β - δ
Where:
α is the bending angle
β is the opening angle of the die or tool
δ is the springback angle
Din 6935 Standard PDF also provides tables and charts that show the recommended values for β and δ for different types of materials, thicknesses, and bending radii.
Springback
the accuracy and consistency of the bending angle and requires correction or compensation. Springback depends on the material, thickness, bending radius, and bending angle of the sheet metal. The higher the springback, the more the sheet metal returns to its original shape or position. The lower the springback, the less the sheet metal returns to its original shape or position.
Din 6935 Standard PDF provides a formula for calculating the springback angle for sheet metal. The formula is:
δ = k * α
Where:
δ is the springback angle
k is the springback coefficient
α is the bending angle
Din 6935 Standard PDF also provides tables and charts that show the recommended values for k for different types of materials, thicknesses, bending radii, and bending angles.
K-factor
The K-factor is a dimensionless factor that represents the location of the neutral axis in a bent sheet metal. The neutral axis is an imaginary line that passes through the sheet metal and divides it into two parts: the inner part that is compressed and the outer part that is stretched. The K-factor depends on the material, thickness, bending radius, and bending angle of the sheet metal. The higher the K-factor, the closer the neutral axis is to the inner surface of the sheet metal. The lower the K-factor, the closer the neutral axis is to the outer surface of the sheet metal.
Din 6935 Standard PDF provides a formula for calculating the K-factor for sheet metal. The formula is:
k = (R - t/2) / R
Where:
k is the K-factor
R is the bending radius
t is the thickness of the sheet metal
Din 6935 Standard PDF also provides tables and charts that show the recommended values for k for different types of materials, thicknesses, bending radii, and bending angles.
