V16 / V25 85° Offset-Mount Double-V Press Brake Lower Die

This double-V press brake lower die, also referred to as a 2V lower die, integrates V16 and V25 openings into one tooling body.

Both V-grooves are manufactured at an 85° die angle and are positioned side by side on the same working surface.

The illustrated configuration has an overall width of 50 mm, an overall height of 46 mm, and a rated load capacity of 80 ton/m.

The V16 and V25 openings provide two relatively large forming ranges within one conventional double-V lower die. The V16 groove provides a medium V-opening, while the larger V25 groove offers increased forming clearance for applications requiring a larger natural inside bend radius or greater material clearance.

Within this W50 same-surface die geometry, the V16 / V25 combination represents a relatively large practical double-V arrangement. As the V-openings increase, more shoulder width and supporting material are required around each groove. Beyond the practical limit of a same-surface configuration, the V-grooves can instead be arranged on separate working faces using a two-face double-V structure.

Another defining feature of this tooling is its offset mounting configuration. The centerline of the plug-in mounting interface is offset relative to the working V-groove positions, distinguishing this structure from centered lower dies.

The V16 / V25 design shown here is one available configuration only. V-opening combinations, die angles, overall dimensions, groove arrangement, mounting centerline position and complete lower-die geometry can all be customized according to customer requirements.

Technical Specifications

Same-Surface Double-V Configuration

The V16 and V25 grooves are positioned side by side on the same working surface.

As V-opening sizes increase, the die requires more space for:

• Groove width
• Shoulder support
• Material between adjacent V-grooves
• Structural rigidity around the working sections

Within the illustrated 50 mm wide die body, V16 and V25 form a relatively large same-surface combination.

When the required V-openings become too large to maintain suitable spacing and supporting material on one working plane, WYS Machinery can use a two-face double-V structure, positioning the grooves on separate working faces.

This allows the die structure to be selected according to the actual V-opening combination rather than forcing all two-groove designs into one cross-section.

Offset Mounting Configuration

The illustrated lower die uses an offset mounting configuration.

The centerline of the plug-in mounting interface is offset relative to the V-groove working positions rather than using a conventional centered relationship.

This configuration can be selected according to:

• Press brake table geometry
• Existing lower die holder
• Machine centerline requirements
• Required tooling position
• Workpiece clearance
• Existing tooling standard
• Customer-specific installation dimensions

WYS Machinery can manufacture both offset and centered lower-die configurations according to the customer's machine and tooling interface.

V16 and V25 Working Openings

The V16 groove provides a medium V-opening suitable for applications requiring a moderate forming width and natural inside bend radius.

The larger V25 groove provides greater forming clearance and can be selected for applications requiring:

• Thicker sheet material
• Larger natural inside bend radii
• Increased workpiece clearance
• Reduced forming force compared with a smaller V-opening under otherwise similar bending conditions

Integrating both V-openings within one lower die provides two useful forming ranges for mixed sheet metal production.

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

Typical Applications

This V16 / V25 double-V lower die is suitable for:

• General sheet metal bending
• Medium-thickness sheet fabrication
• Mixed-thickness production
• Carbon steel bending
• Stainless steel bending
• Electrical cabinet manufacturing
• Industrial enclosure production
• Machinery covers and housings
• Structural sheet metal components
• Applications requiring two medium-to-large V-opening sizes
• Production requiring an offset lower-die mounting position

Maximum Same-Surface V-Opening Combination

For the illustrated W50 × H46 mm die body, the V16 / V25 arrangement represents a relatively large practical combination for positioning two V-grooves on the same working surface.

As V-openings become larger, the available space between the grooves and the amount of supporting shoulder material decrease.

If larger V-openings are required, a different die structure may provide a better solution, such as:

• Wider die body
• Increased overall height
• Two-face double-V configuration
• Different V-opening combination
• Customized mounting geometry

This allows the lower die to maintain sufficient structural support without being restricted to one standard cross-section.

Plug-In Lower Die Mounting System

The illustrated lower die uses a plug-in mounting system.

The bottom profile engages with the corresponding lower die holder or press brake table interface to provide positioning and support during bending.

The illustrated structure uses an offset relationship between the mounting interface and the working V-grooves.

WYS Machinery can customize:

• Plug-in profile
• Mounting dimensions
• Centerline position
• Offset distance
• Overall die cross-section
• Tool length
• Segmentation
• Centered or offset mounting geometry

according to the customer's existing press brake and tooling system.

Custom Double-V Press Brake Dies

WYS Machinery manufactures both standard and customized double-V press brake lower dies, including same-surface, two-face, centered and offset configurations.

The V16 / V25 tooling shown here is one production example rather than a fixed manufacturing limitation.

Customers can customize:

V-opening combination, V-groove angle, overall height, overall width, groove spacing, shoulder geometry, working-face arrangement, mounting centerline position, load capacity, tool length, segmented length and bottom mounting interface.

For non-standard applications, customers can provide the workpiece drawing, material grade, sheet thickness, required bend angle, existing tooling drawing or tooling sample. Our engineering team can evaluate the application and recommend an appropriate lower-die structure.

Compatible Press Brake Tooling Systems

WYS Machinery manufactures 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 plug-in offset configuration shown here represents one reference structure only.

The V-opening, die angle, height, width, groove arrangement, mounting profile and centerline relationship can all be customized according to the customer's machine.

WYS's existing indexed lower-die content already establishes that the company can manufacture single-V, double-V, multi-V and special-purpose lower dies and customize bottom mounting profiles and clamping interfaces, so this page should build on that established capability rather than repeat broad manufacturer wording.
