V80 85° Single-V Press Brake Lower Die for Large V-Opening Bending

This V80 press brake lower die is designed with a robust single-V structure for sheet metal bending applications requiring a large V-opening and a wide, stable die body.

The illustrated model features an 80 mm V-opening, 85° die angle, 90 mm overall height and 100 mm overall width, with a rated load capacity of 100 ton/m.

The V80 opening provides substantial bending clearance and is suitable for applications requiring a larger inside bend radius, wider forming clearance or heavier-gauge sheet metal within the allowable bending capacity.

The 85° V-groove geometry is suitable for air bending applications and provides additional forming allowance when material springback must be considered.

Large V-Opening for Wider Bending Clearance

The 80 mm V-opening provides considerably more forming space than smaller V-dies.

This makes the lower die suitable for applications requiring:

• Large inside bending radii
• Wider workpiece clearance
• Medium and heavier-gauge sheet metal bending
• Larger flange geometries
• Reduced interference around the workpiece during forming

The actual V-opening should be selected according to the material grade, sheet thickness, required inside radius, minimum flange length and bending tonnage.

100 Ton/m Load Capacity

The V80 lower die has a rated load capacity of 100 ton/m.

Its 100 mm wide die body provides a broad and stable support structure around the V-groove for reliable production bending.

Before use, the actual bending force should be evaluated according to the material strength, sheet thickness, bending length and selected V-opening.

Flexible Effective Tool Height

The illustrated lower die has an overall height of 90 mm and a standard effective working height of 75 mm.

Depending on the customer's machine and tooling configuration, the effective height can also be manufactured as:

70 mm or other customized dimensions.

This allows the die to be matched with different punch heights, machine daylight, clamping systems and existing tooling combinations.

V80 Single-V Die Geometry

The illustrated configuration includes:

• V80 / 80 mm V-opening
• 85° die angle
• 90 mm overall height
