How do I select the correct V-die for press brake bending?

Selecting the correct V-die is critical for achieving accurate bending angles, protecting the workpiece surface, and ensuring efficient production in sheet metal fabrication.

Common types of press brake V-dies include:

• Single V-dies, which are commonly used for general bending applications.

• Double V-dies, providing two V openings in one die for improved flexibility.

• Multi-V dies, allowing multiple V openings to support different sheet thicknesses.

• Radius dies, designed to produce specific bending radii on the workpiece.

• Special forming dies, used for applications such as hemming, flattening, offset bending, or other complex forming operations.

When selecting the correct V-die, several factors should be considered, including sheet thickness, material type, bending radius, and required bending angle. A common guideline is that the V-opening should be approximately 6–10 times the sheet thickness, which helps achieve stable bending results and prevents excessive tonnage or material damage.
