V8 / V16 / V24 Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates multiple V-openings into a compact 55 × 55 mm die body, providing several bending groove options within one lower tool.

According to the illustrated configuration, the die incorporates V8, V16 and V24 openings, with multiple V8 and V16 working grooves positioned across different faces of the tooling body. The groove angle shown in the drawing is 85°, and the rated load capacity is 100 ton/m.

Unlike a conventional single-V die or double-V die, a multi-V lower die provides several usable V-openings within one tooling section. The required working face can be selected according to the sheet thickness, required inside bend radius, material properties and bending process.

This multi-face arrangement improves tooling utilization by allowing one lower die to cover a wider range of bending requirements. Instead of preparing and storing several separate single-V dies, multiple forming openings can be integrated into one compact tooling body.

The V8 / V16 / V24 arrangement shown here represents one available configuration only. V-opening sizes, groove combinations, die angles, overall dimensions, working-face arrangement and mounting geometry can all be customized according to the customer's application.

Multi-V Working-Face Design

The defining feature of this lower die is its multi-face, multi-V structure.

Instead of providing only one or two bending openings, several V-grooves are distributed across different working faces of the die body.

The illustrated configuration includes:

Top Working Face
V8 + V16

Side Working Face
V8 + V16

Additional Working Face
V24

This arrangement allows different V-openings to be selected by repositioning the die so that the required groove becomes the active bending surface.

The exact number, size and arrangement of working grooves can be designed according to the customer's required bending range.

V8, V16 and V24 Working Openings

The different V-openings provide different forming characteristics.

The V8 opening provides a relatively small forming width for applications requiring smaller bend radii and thinner sheet material.

The V16 opening provides greater forming clearance and covers a broader range of general sheet metal bending applications.

The larger V24 opening provides additional clearance for thicker material, larger natural inside bend radii and applications requiring a wider die opening.

By combining these V-opening ranges in one die body, the tool can support a broader range of production requirements without requiring a completely separate lower die for every bending condition.

The correct V-opening should always be selected according to:

• Sheet thickness
• Material grade
• Tensile strength
• Required inside bend radius
• Bend angle
• Flange dimensions
• Forming force
• Bending method

Advantages of a Multi-V Press Brake Die

A multi-V lower die can provide several practical advantages in sheet metal production.

Multiple V-Openings in One Tool

Different bending groove sizes are integrated within one die body, allowing a wider range of forming requirements to be covered.

Reduced Tool Changes

When production switches between different sheet thicknesses or bending specifications, the operator can select another working face rather than replacing the complete lower die with a separate tool.

Improved Tooling Utilization

One multi-V tool can perform functions that would otherwise require several individual single-V lower dies.

Compact Tooling Storage

Integrating multiple groove sizes into one tooling body can reduce the total number of separate dies that need to be stored and managed.

Flexible Production

The structure is especially useful for fabrication environments processing multiple sheet thicknesses, materials or component types.

• Industrial sheet metal components
• Small-batch production
• High-mix sheet metal fabrication
• Production requiring several V-opening sizes
• Applications where reducing lower-die changes can improve efficiency

Custom Multi-V Press Brake Dies

WYS Machinery manufactures custom multi-V press brake lower dies according to the customer's machine, tooling system and actual bending requirements.

The illustrated 55 × 55 mm V8 / V16 / V24 configuration is one manufacturing example rather than a fixed product limitation.

Customers can customize:

• Number of V-openings
• V-opening sizes
• Combination of V-openings
• V-groove angles
• Working-face arrangement
• Overall height
• Overall width
• Shoulder geometry
• Groove spacing
• Load capacity
• Tool length
• Segmented length
• Mounting profile
• Positioning structure
• Complete die cross-section

For non-standard applications, customers can provide workpiece drawings, material specifications, sheet thicknesses, required bend angles, press brake model or existing tooling drawings.

Our engineering team can then develop a suitable multi-V lower-die configuration according to the actual production requirements.

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture multi-V lower dies for different press brake tooling standards and machine configurations.

Available configurations include:

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

The structure shown in this drawing is only one reference configuration.

The V-opening arrangement, groove angle, height, width, working-face geometry and mounting interface can all be adapted to the customer's existing press brake.

WYS's currently indexed lower-die content already explicitly states that single-V, double-V, multi-V and special-purpose lower dies can be manufactured with customized V-openings, dimensions and mounting interfaces, so this product page can reinforce that capability with a concrete multi-V product example.
