17-Groove Mixed-Angle Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates 17 physical V-grooves into a 120 × 120 mm tooling body, providing seven different V-opening sizes and two different groove-angle systems within one lower die.

The illustrated configuration includes:

V6 · V8 · V12 · V16 · V20 · V24 · V32

with several V-opening sizes repeated at different working positions.

A defining feature of this product is its mixed-angle configuration. The four V16 grooves use a 30° acute-angle geometry, while the V6, V8, V12, V20, V24 and V32 grooves use 85° geometry.

This allows one multi-V lower die to combine conventional sheet metal bending grooves and acute-angle forming grooves without requiring every working position to use the same die angle.

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

The drawing also indicates an R1.50 groove radius on the acute-angle section, demonstrating that groove radius can be engineered together with V-opening size and groove angle.

The configuration shown here represents one manufacturing example only. WYS Machinery can customize the V-opening sizes, groove quantities, individual groove angles, radii, positions, overall dimensions and mounting structure according to the customer's actual bending requirements.

17-Groove Multi-V Structure

The tooling provides 17 physical V-grooves using seven different V-opening sizes.

The groove distribution is:

V6 × 2
V8 × 2
V12 × 3
V16 × 4
V20 × 2
V24 × 2
V32 × 2

Therefore:

17 physical grooves ≠ 17 different V-opening sizes.

Instead:

17 physical grooves = 7 different V-opening sizes.

Repeated V-openings can be positioned at different locations to provide convenient working orientations or to match a specific production range.

---

Mixed 30° and 85° Groove Geometry

The most distinctive feature of this tooling is that the working grooves do not all use the same angle.

The four V16 openings use 30° geometry, while the other V-openings use 85° geometry.

This enables one multi-V lower die to provide two different forming functions.

85° Working Grooves

The 85° grooves provide conventional forming options for a broad range of general sheet metal bending applications.

30° V16 Grooves

The 30° V16 openings provide acute-angle tooling geometry and can be used, depending on the punch and forming sequence, for applications such as:

• Acute-angle bending
• Pre-bending
• Over-bending for springback compensation
• Multi-stage forming
• Hemming preparation
• Special forming processes

The final punch-and-die combination should always be selected according to the material, thickness, required bend geometry and forming method.

---

V6 to V32 Working Range

The seven V-opening sizes provide a broad range of forming options.

V6 and V8 provide smaller forming openings for applications requiring relatively narrow V-widths.

V12 and V16 cover intermediate forming ranges, with V16 additionally providing the special 30° acute-angle geometry in this configuration.

V20 and V24 provide additional forming clearance for larger natural bend radii and different sheet thickness ranges.

V32 provides the largest V-opening in this illustrated configuration.

The appropriate V-opening should always be selected according to material strength, sheet thickness, required inside radius, flange geometry, bending force and forming method.

---

Individual Groove Angles Can Be Customized

A multi-V lower die does not need every working groove to use one common angle.

This product demonstrates that different V-opening sizes and different groove angles can be combined within the same tooling body.

Depending on the bending requirements, customers can specify:

• 30° acute-angle grooves
• 60° grooves
• 85° grooves
• 88° grooves
• Other customized groove angles

Different working positions can therefore be designed for different forming processes rather than forcing the complete multi-V tool to use one standard angle.

---

Same 120 × 120 mm Body, Different Multi-V Designs

The external dimensions of a multi-V die do not determine its groove configuration.

Different 120 × 120 mm multi-V dies can vary in:

• Number of physical grooves
• Number of different V-opening sizes
• Repeated groove quantities
• V-opening dimensions
• Groove positions
• Groove angles
• Groove radii
• Working-face layouts
• Shoulder geometry

This particular 120 × 120 mm configuration combines 17 grooves with mixed 30° and 85° geometry, while another tool with the same outer dimensions can use a completely different V-opening range or groove strategy.

This flexibility allows the tooling to be designed around the customer's actual production requirements.

Advantages of a Mixed-Angle Multi-V Die

Multiple Forming Functions in One Tool

Conventional 85° grooves and acute-angle 30° grooves are integrated into one lower die.

17 Working Positions

The high groove count provides multiple selectable forming positions.

Seven V-Opening Sizes

V6 through V32 provide different forming ranges for different sheet metal applications.

Reduced Separate Tooling

Different V-opening sizes and angles can be combined within one tool instead of requiring a separate lower die for every forming condition.

Custom Angle Combination

The angle of individual V-grooves can be specified independently according to the customer's production requirements.

Custom Multi-V Press Brake Dies

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

The illustrated 120 × 120 mm, 17-groove V6 / V8 / V12 / V16 / V20 / V24 / V32 mixed-angle configuration represents one manufacturing example rather than a fixed product limitation.

Customers can customize:

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

Customers can provide workpiece drawings, material grade, sheet thickness range, required bending angles, bend radii, press brake model or existing tooling samples for technical evaluation.

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 illustrated 120 × 120 mm structure represents one reference configuration only.

WYS's currently indexed 30° Single-V page already associates its acute-angle tooling with pre-bending and multi-stage forming and explicitly states that angle, V-opening, V-bottom radius and mounting structure can be customized.
