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

This multi-V press brake lower die integrates 13 physical V-grooves into a 90 × 90 mm tooling body, providing eight different V-opening sizes within one lower die.

The illustrated configuration includes:

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

Several of these V-opening sizes are repeated at different positions around the die body, resulting in a total of 13 usable working grooves.

The groove distribution is:

• V6 × 1
• V8 × 2
• V12 × 3
• V16 × 3
• V20 × 1
• V24 × 1
• V32 × 1
• V40 × 1

With a rated load capacity of 100 ton/m, this configuration provides a broad range of forming options within one compact lower tooling body.

A key advantage of custom multi-V tooling is that the external die dimensions do not determine one fixed groove configuration. Two 90 × 90 mm multi-V dies can have completely different numbers of grooves, V-opening sizes, groove positions and groove angles.

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

WYS Machinery can customize the number of V-grooves, V-opening dimensions, repeated groove quantities, groove positions, groove angles, working-face layout, overall dimensions, tooling length and mounting structure according to the actual bending application.

13-Groove Multi-V Structure

The defining feature of this product is its 13-groove multi-V configuration.

Rather than using one groove for every V-opening size, several openings are repeated at different positions around the tooling body.

This design provides:

13 physical working grooves

while using:

8 different V-opening sizes

The repeated V8, V12 and V16 grooves demonstrate that a multi-V die can be configured according to working position and production requirements rather than following a simple one-size-one-groove arrangement.

The groove quantity and distribution can therefore be optimized according to the intended bending range and machine setup.

Eight Different V-Opening Sizes

The illustrated tooling combines:

V6 / V8 / V12 / V16 / V20 / V24 / V32 / V40

within one 90 × 90 mm die body.

The smaller V6 and V8 openings provide relatively narrow forming ranges, while V12 and V16 cover broader general sheet metal bending applications.

The V20 and V24 grooves provide additional forming clearance, and the larger V32 and V40 openings extend the tooling range toward thicker sheet material and larger natural inside bend radii.

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

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

Repeated V-Grooves in One Multi-V Die

A multi-V lower die does not require every physical groove to use a different opening size.

Repeated V-openings can be incorporated at different positions when this provides a more practical working orientation or tooling layout.

In this configuration:

V8 appears twice
V12 appears three times
V16 appears three times

while V6, V20, V24, V32 and V40 each appear once.

This means:

13 physical grooves ≠ 13 different V-opening sizes.

Instead:

13 physical grooves = 8 different V-opening sizes.

This distinction is important when specifying custom multi-V tooling.

Same 90 × 90 mm Body, Different Multi-V Designs

The external dimensions of a multi-V lower die do not define its working-groove configuration.

A 90 × 90 mm multi-V die can be manufactured with different:

• Groove counts
• V-opening sizes
• Repeated groove quantities
• Groove positions
• Groove angles
• Working-face arrangements
• Shoulder geometry
• V-bottom geometry

For example, one 90 × 90 mm WYS configuration integrates 9 physical grooves with 9 different V-opening sizes, while another uses 14 physical grooves with 6 different opening sizes, and this product uses 13 physical grooves with 8 different opening sizes.

This flexibility allows the tooling configuration to be designed around the customer's actual sheet-thickness range and production mix.

Groove Position and Angle Customization

The V-opening size is only one part of a multi-V die design.

The position and angle of each groove can also be configured according to the bending process.

The drawing shown on this page defines one specific groove arrangement, but customers are not limited to this layout.

WYS Machinery can manufacture different groove angles and positions according to:

• Required bend angle
• Material thickness
• Desired inside radius
• Available tooling space
• Press brake configuration
• Operator working orientation
• Customer tooling standards

This makes multi-V tooling highly adaptable to different production environments.

Advantages of a 13-Groove Multi-V Lower Die

Multiple Working Positions

Thirteen physical grooves provide a large number of selectable forming positions within one tooling body.

Wide V-Opening Range

Eight different V-opening sizes cover a broad range of bending requirements.

Reduced Separate Tooling Inventory

Multiple V-opening sizes can be integrated into one lower die instead of requiring numerous separate single-V tools.

Repeated Useful Openings

Frequently required V-opening sizes can be repeated at different locations according to the desired tooling orientation.

Custom Configuration

The entire groove layout can be engineered according to the customer's actual production range rather than following a fixed catalog pattern.

Custom Multi-V Press Brake Dies

WYS Machinery manufactures custom multi-V press brake lower dies according to actual bending requirements.

The illustrated 90 × 90 mm, 13-groove V6 / V8 / V12 / V16 / V20 / V24 / V32 / V40 configuration represents one manufacturing example only.

number of physical grooves, number of different V-opening sizes, repeated groove quantities, V-opening dimensions, groove angles, groove positions, V-bottom geometry, shoulder geometry, working-face arrangement, overall height, overall width, load capacity, tooling length, segmentation and mounting profile.

For non-standard applications, customers can provide:

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

Our engineering team can evaluate the production range and develop an appropriate multi-V tooling configuration.

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 90 × 90 mm profile shown here is only one reference structure.

The number of V-grooves, V-opening sizes, groove positions, groove angles, overall dimensions, working-face geometry and mounting interface can all be customized according to the customer's existing machine.

WYS's currently indexed lower-die pages already tell Google that V-openings, angles, dimensions, positioning structures and mounting interfaces can be customized, while the AMADA Type category explicitly associates WYS with punches, multi-V dies and press brake tooling.
