V50 85° Single-V Press Brake Lower Die for Large V-Opening Bending

This V50 press brake lower die is designed with a robust single-V structure for sheet metal bending applications requiring a large V-opening and stable lower-tool support.

The illustrated model features a 50 mm V-opening, 85° die angle, 90 mm overall height and 75 mm overall width, with a rated load capacity of 100 ton/m.

The V50 opening provides significantly greater forming clearance than smaller V-dies and is suitable for applications requiring a larger inside bend radius, wider flange clearance or thicker sheet metal within the allowable bending capacity.

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

Large V-Opening for Increased Bending Clearance

The 50 mm V-opening offers more working clearance during the bending process and allows the workpiece to form around a larger bending radius.

This makes the die suitable for applications where:

• a wider V-opening is required
• a larger inside radius is preferred
• thicker sheet metal needs to be bent
• greater workpiece clearance is necessary
• wider flange geometries are involved

The actual V-opening should be selected according to the material, thickness, bending angle and required inside radius.

100 Ton/m Load Capacity

With a rated load capacity of 100 ton/m, this V50 lower die is suitable for demanding sheet metal bending applications within the specified capacity.

The 75 mm wide body provides substantial support around the V-groove, helping maintain stable tooling performance during repeated production bending.

Actual bending tonnage should always be calculated according to the sheet thickness, material strength, 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 lower die to be matched with different punches, machine daylight, clamping systems and existing tooling arrangements.

The illustrated configuration includes:

• V50 / 50 mm V-opening
• 85° die angle
