4-Groove V64 / V80 / V100 / V140 Multi-V Press Brake Lower Die

This multi-V press brake lower die integrates four independent working V-grooves into a robust 180 × 180 mm tooling body.

The illustrated configuration includes four different V-opening sizes:

V64 · V80 · V100 · V140

Each working face provides a different large V-opening, allowing the lower die to cover several forming ranges within one tooling body.

With a rated load capacity of 100 ton/m, this configuration is designed around medium-to-large and large V-opening requirements rather than a high number of small grooves.

The V64 and V80 openings provide the smaller forming ranges within this particular tooling configuration. The V100 opening provides substantially greater clearance, while the V140 opening represents the largest working groove in the illustrated design.

The drawing also indicates an R12 radius feature, demonstrating that groove-bottom geometry can be engineered together with the V-opening size.

The 180 × 180 mm external dimensions do not define one fixed multi-V configuration. Other dies with the same body dimensions can be manufactured with completely different groove counts, V-opening sizes, positions, angles and radii.

The tooling shown here therefore represents one available manufacturing example rather than a fixed product limitation.

Technical Specifications

4-Groove Multi-V Structure

The defining feature of this product is its four-groove large-opening multi-V structure.

The tooling integrates:

V64 → V80 → V100 → V140

within one 180 × 180 mm lower-die body.

In this configuration:

4 physical grooves = 4 different V-opening sizes.

Unlike high-density multi-V dies that integrate many smaller grooves, this structure uses only four working faces so that more die-body space can be allocated to large V-openings.

This illustrates an important multi-V design principle:

The optimum number of grooves depends on the required V-opening range rather than on maximizing groove count.

V64 to V140 Working Range

The four V-openings provide progressively larger forming clearance.

V64

The V64 opening provides the smallest working width within this configuration while already belonging to a relatively large V-opening range.

V80

The V80 groove provides greater forming clearance and can support applications requiring larger natural inside bend radii.

V100

The V100 opening provides a substantially wider forming range and increased material clearance.

V140

The V140 groove provides the largest opening in this illustrated configuration, making it suitable for applications requiring very wide die clearance and larger natural bend radii.

The appropriate 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

Large V-Opening Multi-V Configuration

This product is different from many smaller multi-V dies because its design is concentrated on large V-openings rather than high groove density.

A 180 × 180 mm body provides sufficient space to integrate V64, V80, V100 and V140 working grooves while maintaining substantial supporting material around the working sections.

This type of configuration can be useful for:

• Medium and thicker sheet bending
• Larger inside bend-radius requirements
• Applications requiring wide lower-die openings
• Production involving several different large V-opening sizes
• Workshops seeking to reduce the number of separate large single-V dies

The final tooling configuration should always be evaluated according to the actual forming force and workpiece requirements.

Custom V-Bottom Geometry

The drawing indicates an R12 radius feature, demonstrating that a large V-opening does not need to use one fixed groove-bottom profile.

WYS Machinery can customize:

• V-bottom radius
• Shoulder radius
• Groove angle
• Groove depth
• V-opening width
• Groove position

Different working grooves within one multi-V die can therefore be designed with different geometry according to the required forming process.

Same 180 × 180 mm Body, Different Groove Configurations

The external dimensions of a multi-V lower die do not define one fixed working structure.

Different 180 × 180 mm multi-V dies can be manufactured with different:

• Groove counts
• V-opening sizes
• Groove positions
• Groove angles
• V-bottom radii
• Working-face arrangements
• Shoulder geometries

The V64 / V80 / V100 / V140 arrangement shown here is one reference configuration only.

Another 180 × 180 mm die can use a completely different groove strategy according to the customer's sheet-thickness range and production requirements.

Advantages of This 4-Groove Design

Four Large Forming Ranges

Four distinct large V-openings are integrated into one tooling body.

V64 to V140 Coverage

The die provides a broad large-opening range without requiring a separate tool for every V size.

Reduced Large-Tool Inventory

Several large V-opening functions can be combined within one lower die.

Robust Tooling Geometry

The relatively low groove count allows substantial body material to remain around the large V-openings.

Custom Engineering

Opening size, groove angle, position, radius and overall tooling geometry can all be designed according to the customer's bending requirements.

Typical Applications

This 180 × 180 mm multi-V lower die is suitable for:

• Medium and thicker sheet bending
• Carbon steel bending
• Stainless steel bending
• Structural sheet metal fabrication
• Machinery and heavy equipment components
• Large industrial sheet metal parts
• Large enclosure fabrication
• Applications requiring larger natural inside bend radii
• Applications requiring V64 to V140 forming ranges
• Mixed-production environments using several large V-openings
• Workshops seeking to reduce separate large lower-die inventory

Custom Multi-V Press Brake Dies

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

The illustrated 180 × 180 mm, 4-groove V64 / V80 / V100 / V140 configuration represents one manufacturing example only.

Customers can customize:

number of V-grooves, V-opening sizes, 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 specifications, sheet thickness ranges, required bending angles, required inside radii, existing tooling drawings or press brake information 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 180 × 180 mm structure shown here is one reference design only.

The V-opening combination, groove angle, groove position, V-bottom geometry, overall dimensions and mounting interface can all be adapted according to the customer's machine.

WYS's currently indexed lower-die content already establishes that V-opening, angle, V-bottom radius, die geometry and mounting interface can be customized, while Google currently identifies WYS with punches and multi-V dies through its main Press Brake Tooling and AMADA Type Tooling pages.
