V40 85° Single-V Press Brake Lower Die for Wider V-Opening Bending

This V40 press brake lower die is designed with a robust single-V structure for sheet metal bending applications requiring a relatively wide V-opening and stable lower-tool support.

The illustrated model features a 40 mm V-opening, 85° die angle, 90 mm overall height and 50 mm body width, with a rated load capacity of 100 ton/m.

The V40 opening provides greater forming clearance than smaller V-dies and is suitable for applications requiring a larger inside bend radius, wider die opening or increased clearance around the workpiece during bending.

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

Stable 100 Ton/m Lower Die Structure

With a rated load capacity of 100 ton/m, this V40 lower die provides a stable tooling solution for demanding sheet metal bending applications within its specified capacity.

The 50 mm wide body provides strong support around the V-groove and helps maintain consistent tooling performance during repeated production bending.

For safe and accurate production, actual bending tonnage should be determined according to the material grade, tensile strength, sheet thickness, V-opening and bending length.

Flexible Effective Tool Height

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

According to 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 adapted to different punch heights, machine daylight, clamping systems and existing tooling arrangements.

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture customized 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 is not limited to the mounting profile shown in the drawing. The bottom interface, positioning geometry, tool height and cross-section can all be adapted according to the customer's machine and tooling system.

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

Custom V-Opening, Angle and Die Geometry

The V40 opening and 85° die angle shown on this page are one available configuration.

Different V-openings and die angles can be manufactured according to:

• Sheet thickness
• Material type and strength
• Required bending angle
• Required inside radius
• Minimum flange dimension
• Material springback
• Press brake capacity

The shoulder radius, edge geometry and lower die body dimensions can also be customized as part of the complete tooling solution.

Custom Press Brake Tooling Design Service

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

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

Our engineering team can evaluate the bending requirement and recommend an appropriate lower die configuration.

The tooling can then be manufactured with the required V-opening, angle, overall height, effective height, width, radius, length and mounting structure.
