14-Groove V6 / V8 / V12 / V16 / V20 / V24 Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates 14 physical V-grooves into a 90 × 90 mm tooling body, providing six different V-opening sizes within one lower die.

The illustrated configuration includes:

V6 · V8 · V12 · V16 · V20 · V24

with several V-opening sizes repeated on different positions around the die body.

The groove distribution is:

• V6 × 3
• V8 × 2
• V12 × 2
• V16 × 3
• V20 × 2
• V24 × 2

This gives a total of 14 usable V-grooves within one multi-V tooling section.

With a rated load capacity of 100 ton/m, the die provides multiple forming options for production involving different sheet thicknesses, bend radii and workpiece requirements.

A major advantage of multi-V tooling is that the same external die dimensions can support completely different working-groove configurations. For example, another 90 × 90 mm lower die can contain fewer grooves, larger V-openings or a completely different arrangement of groove positions and angles.

The 14-groove configuration shown here therefore represents one manufacturing example rather than a fixed standard profile.

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

14-Groove Multi-V Structure

The defining feature of this product is its high-density 14-groove multi-V configuration.

Instead of using only one groove of each V-opening size, several groove sizes are repeated at different positions around the die body.

The illustrated configuration provides:

3 × V6
2 × V8
2 × V12
3 × V16
2 × V20
2 × V24

This structure allows multiple working positions to be integrated into one compact 90 × 90 mm lower die.

The exact reason for repeating a particular V-opening can depend on the required tooling layout, working-face orientation, press brake setup and customer production requirements.

The number and location of repeated V-grooves can therefore be customized rather than following one fixed pattern.

Six Different V-Opening Sizes

Although this die contains 14 physical grooves, it uses six different V-opening sizes.

V6

Three V6 grooves are integrated into the tooling configuration, providing small forming openings for applications requiring narrow V-widths.

V8

Two V8 grooves provide an additional small-opening range.

V12

Two V12 grooves extend the forming range toward general thin-sheet and precision bending applications.

V16

Three V16 grooves provide a medium V-opening range for broader general sheet metal bending requirements.

V20

Two V20 grooves provide additional forming clearance and larger natural bend radii.

V24

Two V24 grooves provide the largest V-opening size in this illustrated configuration.

The actual working groove should always be selected according to material grade, sheet thickness, tensile strength, required inside radius, flange geometry and bending method.

Repeated V-Grooves on a Multi-V Die

A multi-V lower die does not necessarily need every groove to have a different V-opening size.

Repeated V-grooves can be incorporated at different locations when this provides a more practical tooling configuration for the machine, working orientation or production process.

This illustrated 90 × 90 mm die demonstrates that distinction clearly:

14 physical grooves ≠ 14 different V-opening sizes.

Instead:

14 physical grooves = 6 different V-opening sizes.

This allows the tooling layout to be designed around actual production requirements rather than following a simple one-groove-per-size structure.

---

Same 90 × 90 mm Size, Completely Different Groove Layout

The most important characteristic of custom multi-V tooling is that the external dimensions do not determine the internal V-groove arrangement.

Two 90 × 90 mm multi-V dies can differ completely in:

• Total number of V-grooves
• Number of different V-opening sizes
• Repeated groove quantities
• V-opening dimensions
• Groove positions
• Groove angles
• Working-face layout
• Shoulder geometry
• V-bottom geometry

For example, one 90 × 90 mm multi-V die may provide 9 different V-openings, while another 90 × 90 mm die can provide 14 physical grooves using 6 different V-opening sizes.

The tooling should therefore be selected or designed according to the actual bending range rather than external size alone.

Advantages of a High-Groove-Count Multi-V Die

Multiple Working Options

Fourteen V-grooves provide a large number of working positions within one lower tooling body.

Broad Bending Flexibility

Six V-opening sizes provide different forming ranges for different sheet thicknesses and bend-radius requirements.

Reduced Separate Tooling

Several V-opening sizes and repeated working positions can be integrated into one die instead of requiring numerous separate single-V tools.

Flexible Groove Arrangement

V-opening sizes do not need to appear only once. Repeated grooves can be positioned where required by the tooling design.

Custom Production Range

The entire groove configuration can be developed according to the customer's actual workpiece range and press brake setup.
