V20 60° Single-V Press Brake Lower Die for Acute-Angle Bending

This V20 press brake lower die is designed with a single-V structure for sheet metal forming applications requiring a 60° groove and a relatively wide V-opening.

The illustrated configuration features a 20 mm V-opening, 60° die angle, 90 mm overall height and 30 mm body width, with a rated load capacity of 60 ton/m.

The combination of the V20 opening and 60° V-groove geometry makes this lower die suitable for acute-angle air bending, pre-bending and multi-stage forming operations where a narrower included angle is required than with conventional 85°, 88° or 90° lower dies.

Compared with smaller V-opening acute-angle dies, the V20 opening provides increased forming clearance and can accommodate applications requiring a larger inside bending radius or wider flange geometry.

60° V-Groove for Acute-Angle Forming

The 60° die angle is suitable for bending operations where the workpiece must be formed beyond the conventional right-angle range.

Typical applications include:

• Acute-angle air bending
• Pre-bending operations
• Multi-stage bending
• Precision flange forming
• Components requiring springback allowance
• Customized acute-angle sheet metal parts

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

V20 Single-V Die Geometry

The illustrated lower die combines a 20 mm V-opening with a 30 mm body width, providing stable support around the forming zone.

Main dimensions include:

• V20 / 20 mm V-opening
• 60° die angle
• 90 mm overall height
• 75 mm effective height
• 30 mm body width
• 14 mm bottom mounting width
• Approx. R2.5 shoulder radius
• 60 ton/m load capacity

The die angle, shoulder geometry and surrounding edge dimensions can also be customized according to the customer's bending process and workpiece requirements.

Custom Effective Tool Height

The illustrated model has a standard effective working height of 75 mm.

The effective height can also be manufactured according to the customer's:

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

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