V20 35° Single-V Press Brake Lower Die for Sharp Acute-Angle Bending

This V20 press brake lower die is designed with a single-V structure for sheet metal forming applications that require a sharp 35° V-groove and increased bending clearance.

The illustrated configuration features a 20 mm V-opening, 35° die angle, 90 mm overall height and 35 mm body width, with a rated load capacity of 70 ton/m.

The combination of the V20 opening and 35° 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° lower dies.

Compared with smaller V8, V10, V12 and V16 acute-angle dies, the V20 opening provides greater forming clearance and is suitable for applications requiring a larger bending radius or broader workpiece geometry.

35° V-Groove for Acute-Angle Forming

The 35° die angle is designed for bending processes where the workpiece must be formed to a very acute included angle.

Typical applications include:

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

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

V20 Single-V Die Geometry

The illustrated lower die combines a 20 mm V-opening with a 35 mm body width, providing a robust and stable support structure around the forming zone.

Main dimensions include:

• V20 / 20 mm V-opening
• 35° die angle
• 90 mm overall height
• 75 mm effective height
• 35 mm body width
• 14 mm bottom mounting width
• Approx. R2.5 shoulder radius
• 70 ton/m load capacity

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

Custom Effective Tool Height

The illustrated configuration has a standard 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.
