V12 85° Single-V Press Brake Lower Die for Precision Sheet Metal Bending

This V12 press brake lower die is designed with a single-V structure for precise and repeatable sheet metal bending.

The illustrated model features a 12 mm V-opening, 85° die angle, 90 mm overall height and 25 mm overall width. The load-bearing section around the bending zone is 20 mm wide, and the die is rated for 60 ton/m.

The V12 opening provides a practical balance between bending clearance and support, making the die suitable for a wide range of thin and medium-gauge sheet metal applications. The 85° V-groove angle provides additional forming range for air bending operations where material springback needs to be considered.

Flexible Effective Tool Height

The standard configuration shown has an effective working height of 75 mm.

According to the customer's press brake configuration and tooling combination, the effective height can also be manufactured as:

70 mm or other customized dimensions.

This allows the lower die to be adapted to different punch heights, machine daylight, clamping systems and existing tooling setups.

V12 Single-V Die Geometry

The illustrated lower die combines a 12 mm V-opening with a 20 mm load-bearing section width, providing stable support around the V-groove.

Main dimensions include:

• V12 / 12 mm V-opening
• 85° die angle
• 90 mm overall height
• 75 mm effective height

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture customized lower dies for different press brake brands, tooling standards and clamping systems.

Available configurations include:

TRUMPF Type, WILA Type, LVD Type, Bystronic Type, Amada / Promecam Type, European Type and other customized press brake tooling systems.

The lower die cross-section and mounting structure can be adapted according to the customer's machine and tooling system.

Customers can provide a machine model, existing tooling drawing, tooling cross-section, sample or workpiece drawing for technical evaluation.

Custom Die Angle and Geometry

The 85° angle shown in the drawing is one available configuration.

Different die angles, edge dimensions and shoulder geometries can be manufactured according to the required bending angle, material properties, springback behavior and workpiece geometry.

The V-opening, die angle, shoulder radius and surrounding dimensions can therefore be customized as part of the complete tooling solution.
