V8 / V12 85° Double-V Press Brake Lower Die

This double-V press brake lower die combines V8 and V12 openings in one compact die body, providing two commonly used V-groove sizes for general sheet metal bending applications.

Both V-openings are manufactured at an 85° die angle. The illustrated configuration has an overall width of 50 mm, an overall height of 26 mm, and a rated load capacity of 80 ton/m.

The V8 / V12 combination is a practical choice for many sheet metal fabrication environments because it allows two frequently used lower-die openings to be integrated into a single tool. This can reduce the need to prepare separate single-V dies when production includes different sheet thicknesses, required bend radii or component specifications.

The illustrated version uses a plug-in mounting system, providing a defined interface with the corresponding lower die holder or press brake table system.

The V8 / V12 configuration shown here is one available example. Other V-opening combinations, die angles, body dimensions, load capacities and mounting structures can be manufactured according to customer requirements.

Common V8 / V12 Double-V Configuration

The V8 / V12 combination is frequently used because both V-opening sizes are suitable for a wide range of general sheet metal bending applications.

Using these two V-grooves within one lower die can provide practical flexibility when production includes:

• Different sheet thicknesses
• Different required inside bend radii
• Different material grades
• Mixed production batches
• Frequent changes between smaller and larger V-openings

The actual V-opening should always be selected according to the workpiece material, sheet thickness, bending method, desired inside radius and forming force.

Typical Applications

This V8 / V12 double-V press brake die is suitable for:

• General sheet metal bending
• Thin and medium sheet fabrication
• Electrical enclosure production
• Metal cabinet manufacturing
• Machine cover fabrication
• Equipment housing production
• Stainless steel sheet bending
• Carbon steel sheet bending
• Mixed-batch sheet metal production
• Precision fabrication requiring two commonly used V-openings

The appropriate V-opening should be selected according to the actual bending application.

Plug-In Lower Die System

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

This configuration allows the lower die to engage with a corresponding die holder or press brake table interface while maintaining accurate positioning during bending.

The plug-in structure shown in the drawing is only one reference configuration.

WYS Machinery can customize the lower mounting interface according to:

• Press brake model
• Existing lower die holder
• Tooling drawing
• Existing tooling sample
• Required machine standard

The bottom profile and complete cross-section can therefore be adapted to different press brake systems.

Custom Double-V Press Brake Dies

WYS Machinery manufactures both standard and customized double-V press brake lower dies.

The V8 / V12 configuration shown on this page is one example rather than a fixed manufacturing limitation.

Customers can customize:

V-opening combination, die angle, overall height, overall width, shoulder geometry, load capacity, tool length, segmented length, bottom mounting profile and positioning structure.

For non-standard applications, customers can provide:

• Workpiece drawings
• Material grade
• Sheet thickness
• Required bending angle
• Existing tooling drawings
• Press brake model

Our engineering team can then evaluate the application and recommend a suitable lower die configuration.

Compatible Press Brake Tooling Systems

WYS Machinery can manufacture double-V and multi-V lower dies for different press brake tooling standards.

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 mounting profile shown in this drawing is only one reference configuration.

Different mounting geometries can be manufactured according to the customer's existing machine and tooling interface.
