V8 85° Single-V Press Brake Lower Die for Precision Bending

This V8 press brake lower die is designed with a single-V structure for precision sheet metal bending applications requiring a relatively small V-opening and stable lower-tool support.

The illustrated model features an 8 mm V-opening, 85° die angle, 90 mm overall height and 25 mm overall width. The load-bearing section around the bending area is 16 mm wide, and the die has a rated load capacity of 40 ton/m.

The V8 opening is suitable for thin sheet metal and precision flange bending applications where a relatively small die opening is required. The 85° V-groove angle provides additional flexibility for air bending operations where material springback needs to be considered.

Customized Effective Height

The standard configuration shown has an effective working height of 75 mm.

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

70 mm or other customized dimensions.

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

V8 Single-V Die Geometry

The illustrated die combines an 8 mm V-opening with a 16 mm load-bearing section width, providing reliable support around the V-groove.

Main dimensions include:

• V8 / 8 mm V-opening
• 85° die angle
• 90 mm overall height
• 75 mm effective height
• 25 mm overall width
• 16 mm load-bearing section width
• Approx. R1 shoulder radius

Technical Specifications

Typical Applications

This V8 85° single-V lower die is suitable for a wide range of precision sheet metal bending operations, including:

• Thin sheet metal bending
• Precision air bending
• Small flange forming
• Relatively small inside-radius bending
• Electrical cabinet components
• Control panels
• Sheet metal enclosures
• Machinery components
• Stainless steel sheet parts
• Mild steel components
• General CNC press brake bending

The appropriate die configuration should be selected according to the material type, sheet thickness, required bending angle, inside radius, minimum flange length and bending tonnage.

Standard & Custom Options

The V8 lower die shown on this page represents one typical configuration only.

WYS Machinery can customize:

• V-opening
• die angle

In addition to V8, other V-openings can be manufactured according to the customer's material thickness, bending radius and forming requirements.

Single-V, multi-V and other customized lower die structures are also available.

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture lower dies for different press brake brands, tooling standards and clamping systems.

Available configurations include:

TRUMPF Type, WILA Type, LVD Type, Bystronic Type, Amada / Promecam Type, European Type and other customized press brake tooling systems.

The lower die cross-section and mounting structure can be adapted according to the customer's machine and tooling system.

Customers can provide a machine model, existing tooling drawing, tooling cross-section, sample or workpiece drawing for technical evaluation.

Custom Die Angle and Geometry

The 85° angle shown in the drawing is one available configuration.

Different die angles, edge dimensions and shoulder geometries can be manufactured according to the required bending angle, springback characteristics, material properties and workpiece geometry.

The V-opening, die angle, shoulder radius and surrounding dimensions can therefore be customized as part of the complete tooling solution.

Custom Press Brake Tooling Design Service

Customers who are unsure which V-opening, die angle or lower die structure should be selected can provide:

workpiece drawing, material type, sheet thickness, required bending angle and press brake model.

Our engineering team can recommend a suitable lower die according to the actual bending requirement.

The V-opening, angle, overall height, effective height, width, radius, length and mounting structure can all be customized.
