9-Groove V6 / V8 / V12 / V16 / V20 / V24 / V32 / V40 / V48 Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates nine independent working V-grooves into a 90 × 90 mm tooling body, providing a broad range of V-opening sizes within one lower die.

The illustrated configuration includes:

V6 · V8 · V12 · V16 · V20 · V24 · V32 · V40 · V48

Each V-opening is positioned on a different location or working face of the die body, allowing the required groove to be selected according to the workpiece, material thickness, target bend radius and forming process.

The V48 groove shown in the drawing is manufactured with an 85° angle. The remaining groove angles are part of the illustrated tooling geometry and can also be customized according to the actual bending requirement.

With a rated load capacity of 100 ton/m, the die covers a wide progression from very small V-openings to much larger forming openings within one tooling body.

This type of multi-V structure is especially useful in production environments where different sheet thicknesses, bend radii and forming requirements need to be handled without preparing a separate single-V lower die for every job.

The 90 × 90 mm body size does not define one fixed groove configuration. Another 90 × 90 mm multi-V lower die can use completely different V-opening sizes, groove positions or angles depending on the customer's production requirements.

The configuration shown here is therefore one manufacturing example rather than a fixed catalog limitation.

Nine-Groove Multi-V Structure

The defining feature of this lower die is its nine-groove multi-V structure.

Instead of using one, two or several limited V-openings, this configuration integrates a broad sequence of forming grooves:

V6 → V8 → V12 → V16 → V20 → V24 → V32 → V40 → V48

This provides a very wide range of forming options within one tooling body.

When another V-opening is required, the lower die can be repositioned so that the selected groove becomes the active working surface.

Compared with a conventional single-V or double-V die, the nine-groove structure offers substantially greater flexibility for mixed sheet metal production.

---

V6 to V48 Working Range

The different V-openings cover a broad range of forming requirements.

V6 and V8

These smaller openings provide narrow forming widths for thin-sheet bending and applications requiring relatively small natural inside radii.

V12 and V16

These grooves provide intermediate forming widths suitable for a broad range of general sheet metal bending applications.

V20 and V24

These openings provide greater forming clearance and are suitable for applications requiring larger bend radii or thicker material than the smaller V-grooves.

V32 and V40

These larger openings extend the tooling range toward medium and thicker sheet bending applications.

V48

The V48 groove provides the largest opening in this configuration and is shown with an 85° groove angle.

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

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

Same 90 × 90 mm Body, Different Groove Configurations

An important feature of custom multi-V tooling is that external die dimensions do not determine the internal groove configuration.

Two multi-V lower dies with the same 90 × 90 mm body size can have completely different:

• V-opening sizes
• Number of grooves
• Groove positions
• Groove angles
• Working-face arrangements
• Shoulder geometries
• V-bottom geometries

This allows the tooling to be configured directly around the customer's required sheet-thickness range and production mix.

The illustrated nine-groove configuration is therefore one example of what can be manufactured within a 90 × 90 mm die body.

---

Groove Position and Angle Customization

The position and angle of each V-groove can be selected according to the intended bending process.

The illustrated V48 groove uses an 85° angle, while different groove angles can be incorporated into other working faces when required.

This means a multi-V die can combine:

different V-opening sizes + different groove positions + different groove angles

within the same tooling body.

This flexibility allows one multi-V die to be engineered for a much broader production range than a fixed single-V lower die.

Advantages of a 9-Groove Multi-V Lower Die

The nine-groove structure provides several practical advantages:

Wide Forming Range

V-openings from V6 to V48 provide multiple bending ranges within one lower tool.

Reduced Tooling Inventory

Several forming openings are integrated into one tooling body, reducing the number of separate single-V lower dies required.

Flexible Mixed Production

The wide range of V-openings is useful for workshops processing different sheet thicknesses, materials and component specifications.

Faster Tooling Selection

The appropriate groove can be selected by repositioning the die rather than installing a completely separate lower tooling body.

Custom Groove Layout

The groove count, size, angle and position can be designed around the customer's production requirements.

• Material grade
• Required bend angles
• Required inside radii
• Press brake model
• Existing tooling drawings
• Existing die samples

Our engineering team can evaluate the application and develop an appropriate multi-V lower die configuration.
