V12 35° Single-V Press Brake Lower Die for Sharp Acute-Angle Bending

This V12 press brake lower die is designed with a single-V structure for sheet metal bending applications requiring a sharp 35° groove and controlled acute-angle forming.

The illustrated model features a 12 mm V-opening, 35° die angle, 90 mm overall height and 24 mm body width, with a rated load capacity of 70 ton/m.

The combination of the V12 opening and 35° V-groove geometry makes this lower die suitable for sharp acute-angle air bending, pre-bending and multi-stage forming operations where a much narrower included angle is required than with conventional 60°, 85°, 88° or 90° dies.

Compared with smaller V8 and V10 35° dies, the V12 opening provides additional forming clearance and supports applications requiring a larger inside bending radius while maintaining a compact lower-tool profile.

35° V-Groove for Sharp Acute-Angle Forming

The 35° die angle provides a narrow included angle for demanding acute-angle bending applications.

Typical forming requirements can include:

• Sharp acute-angle air bending
• Pre-bending operations
• Multi-stage forming processes
• Precision flange bending
• Components requiring additional springback allowance
• Preparation for subsequent forming operations
• Customized acute-angle sheet metal components

The appropriate tooling configuration should be selected according to the material, sheet thickness, required bending angle and workpiece geometry.

V12 Single-V Die Geometry

The illustrated lower die combines a 12 mm V-opening with a 24 mm body width, providing stable support around the forming zone.

Main dimensions include:

• V12 / 12 mm V-opening
• 35° die angle
• 90 mm overall height
• 75 mm effective height
• 24 mm body width
• 14 mm bottom mounting width
• Approx. R1.5 shoulder radius
• 70 ton/m load capacity

The die angle, shoulder geometry and surrounding edge dimensions can also be customized according to the required bending process.

Custom Effective Tool Height

The illustrated configuration has an effective working height of 75 mm.

The effective height is not limited to this dimension and can be manufactured according to the customer's:

• Press brake configuration
• Upper tooling height
• Machine daylight
• Clamping system
• Existing tooling combination

The overall tool height and effective height can therefore be coordinated as part of the complete tooling solution.
