V40 85° Wide-Base Single-V Press Brake Lower Die

This V40 85° press brake lower die uses a full-width rectangular base with a single V-groove, providing a stable lower-tool configuration for sheet metal air bending.

The illustrated configuration features:

V-Opening: V40 / 40 mm
Die Angle: 85°
Overall Height: 60 mm
Overall / Base Width: 60 mm
Groove Radius: R4
Rated Load Capacity: 100 ton/m

The main structural difference between this lower die and a conventional plug-in lower die is its mounting profile. Rather than using a narrow bottom shank, this model maintains a 60 mm full-width supporting base below the bending groove.

The dimensions shown represent one available configuration rather than a fixed manufacturing limitation. WYS Machinery can manufacture the complete lower-die profile according to the customer's press brake, die holder, workpiece and forming requirements.

85° Single-V Groove for Precision Air Bending

The illustrated lower die uses an 85° V-groove, suitable for precision air-bending applications where angular allowance may be required to compensate for material springback.

The final bend result depends on several factors, including:

• Material grade
• Sheet thickness
• V-opening
• Punch angle
• Material springback
• Required inside bend radius
• Minimum flange dimension
• Required bending force

The 85° groove shown on this page is one available specification. Other die angles can also be manufactured according to the customer's bending process.

V40 Opening for Increased Forming Clearance

The 40 mm V-opening provides a relatively large forming zone and greater clearance around the sheet during bending.

Compared with smaller V-opening dies such as V32, the V40 configuration provides additional forming space and is suitable for applications requiring a larger inside bend radius or broader workpiece geometry.

The appropriate V-opening should be selected according to sheet thickness, material properties, required bend radius and flange dimensions.

Wide-Base Structure Instead of Plug-in Mounting

This model uses a full-width 60 mm wide base.

A typical plug-in lower die uses a narrower bottom shank that fits into a compatible die holder. This wide-base lower die does not use that narrow plug-in section.

Instead, the body and base remain full width, providing a broader supporting structure beneath the V-groove.

This type of lower die can be used where the machine or tooling system requires:

• Full-width lower-die support
• Wide-base mounting geometry
• A different lower-die holder structure
• Special positioning arrangements
• Customized mounting interfaces

The mounting structure can also be redesigned according to the customer's press brake and die holder.

Compact H60 × W60 mm Profile

The illustrated lower die has:

Overall Height: 60 mm
Overall / Base Width: 60 mm

This creates a compact wide-body profile while maintaining a rated load capacity of 100 ton/m.

Both height and width can be customized to match different machine and tooling combinations.

R4 Groove Radius

The illustrated V40 groove uses R4 radius geometry.

The groove radius can also be customized according to the V-opening, sheet thickness, required bend radius and forming process.

Standard & Custom Options

The V40 85° wide-base lower die shown on this page represents one available configuration only.

WYS Machinery can customize:

• V-opening
• die angle
• overall height
• effective height
• overall width
• base width
• groove radius
• shoulder geometry
• edge dimensions
• tool length
• segmented length

In addition to wide-base single-V lower dies, WYS Machinery can also manufacture plug-in single-V dies, T-type single-V dies, double-V dies, multi-V dies and other customized lower-die structures.

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture lower dies for different press brake brands, tooling standards and clamping systems.

Available configurations include:

TRUMPF Type, WILA Type, LVD Type, Bystronic Type, Amada / Promecam Type, European Type and other customized press brake tooling systems.

The wide-base mounting structure shown here is one available design only.

The bottom mounting profile, base structure, tool height, overall width and complete die cross-section can all be adapted according to the customer's press brake.

Customers can provide a machine model, existing tooling drawing, lower-die cross-section, die-holder dimensions, tooling sample or workpiece drawing for technical evaluation.

Custom V-Opening and Die Angle

The V40 opening and 85° angle are not fixed limitations.

Different V-openings and die angles can be manufactured according to:

• Material type
• Sheet thickness
• Required bending angle
• Required inside radius
• Minimum flange dimension
• Material springback
• Required forming clearance
• Required bending force
• Press brake configuration

This allows the lower die to be manufactured around the actual workpiece rather than limiting customers to one fixed standard profile.

Custom Mounting Structure

Single-V lower dies can use different mounting and base structures.

WYS Machinery can manufacture:

Wide-Base Structure
Plug-in Mounting Structure
T-Type Structure
Other Customized Lower-Die Interfaces

The appropriate mounting profile can be selected according to the customer's machine, lower-die holder and tooling system.

Custom Press Brake Tooling Design Service
