10-Groove V6 / V8 / V12 / V16 / V22 / V24 / V32 / V48 / V64 / V80 Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates 10 independent working V-grooves into a 120 × 120 mm tooling body.

The illustrated configuration contains ten different V-opening sizes:

V6 · V8 · V12 · V16 · V22 · V24 · V32 · V48 · V64 · V80

Unlike high-groove-count multi-V configurations where several V-opening sizes may be repeated, every working groove in this design has a different V-opening size.

The result is a very broad forming range within one lower tooling body, progressing from the compact V6 opening to the substantially larger V80 opening.

The illustrated lower die has an overall cross-section of 120 × 120 mm and a rated load capacity of 100 ton/m.

The V64 groove is shown with an 85° angle in the drawing. Other groove angles can be configured according to the required bending process.

Another important feature visible in this design is the use of different groove-bottom geometries. Larger V-openings can incorporate rounded bottom profiles where required, demonstrating that multi-V tooling can be customized not only by V-opening width but also by groove angle, bottom radius and shoulder geometry.

The configuration shown here represents one available manufacturing example rather than a fixed catalog limitation. WYS Machinery can develop different multi-V arrangements according to the customer's sheet thickness range, workpiece drawings and press brake configuration.

10-Groove Multi-V Structure

The defining feature of this product is its 10-groove multi-V configuration.

Unlike multi-V designs where the same V-opening is repeated on several working positions, this configuration uses ten different V-opening sizes for ten physical grooves.

The working range progresses through:

V6 → V8 → V12 → V16 → V22 → V24 → V32 → V48 → V64 → V80

This provides a particularly broad selection of forming widths within one lower tooling body.

The required working groove can be selected according to:

• Sheet thickness
• Material grade
• Desired inside bend radius
• Bend angle
• Flange geometry
• Required forming force
• Production process

---

Wide V6 to V80 Working Range

One of the most important characteristics of this lower die is the broad difference between its smallest and largest V-opening.

Small V-Openings

V6 / V8 / V12 / V16

These openings provide relatively narrow forming widths for thinner sheet and applications requiring smaller natural inside bend radii.

Medium V-Openings

V22 / V24 / V32

These sizes provide additional forming clearance and cover a broad range of general sheet metal bending requirements.

Large V-Openings

V48 / V64 / V80

These larger grooves substantially increase forming clearance and extend the tooling range toward applications involving thicker material and larger natural inside bend radii.

The correct V-opening should always be selected according to the actual bending conditions rather than using one fixed V-width rule for every material.

---

V64 85° Working Groove

The drawing specifically identifies the V64 working groove with an 85° angle.

This provides a large V-opening while maintaining conventional 85° lower-die geometry.

Other working grooves within a multi-V tool do not necessarily need to use the same angle.

Depending on the customer's production requirements, individual working grooves can be designed with different angles, such as:

30° · 60° · 85° · 88° · other customized angles

This makes it possible to combine different forming processes within one multi-V tooling body.

---

Custom Groove-Bottom Geometry

Multi-V lower dies can also use different V-bottom profiles and radii on different working grooves.

For larger V-openings, a rounded bottom geometry can be selected when required by the tooling design or forming application.

Available customization can include:

• V-bottom radius
• Sharp or rounded groove bottom
• Shoulder radius
• V-opening width
• Groove angle
• Groove depth
• Groove position

This means the V-opening dimension alone does not completely define a multi-V die.

---

Same 120 × 120 mm Body, Completely Different Working Range

This product provides another clear example that the external dimensions of a multi-V lower die do not define its internal groove configuration.

WYS can manufacture different 120 × 120 mm lower dies with:

• Different groove counts
• Different V-opening ranges
• Repeated or non-repeated V sizes
• Different groove positions
• Different groove angles
• Different bottom radii
• Different working-face arrangements

For example, another 120 × 120 mm configuration may contain 17 physical grooves concentrated between V6 and V40, while this product contains only 10 grooves but extends all the way to V80.

These two configurations are not better or worse than each other; they are designed for different production requirements.

Advantages of This 10-Groove Multi-V Design

Ten Different Forming Ranges

Each of the ten physical grooves provides a different V-opening size.

Very Wide V-Opening Coverage

The V6-to-V80 range combines small, medium and large V-openings in one tooling body.

Reduced Separate Lower-Die Inventory

Multiple forming openings can replace several independent single-V lower dies in mixed-production environments.

Flexible Production

The die can accommodate a broader range of sheet thicknesses and bending requirements by selecting different working faces.

Custom Geometry

V-opening size, position, angle, bottom radius and complete cross-section can all be redesigned according to the customer's requirements.

• Machinery and equipment manufacturing
• Structural sheet metal components
• Electrical cabinet fabrication
• Industrial enclosure production
• High-mix production
• Small- and medium-batch manufacturing
