V12 / V20 85° Double-V Press Brake Lower Die

This double-V press brake lower die, also known as a 2V lower die, combines V12 and V20 openings in one compact die body.

Both V-grooves 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 two integrated V-openings provide greater flexibility for sheet metal bending. The V12 groove can be used for smaller-opening bending requirements, while the larger V20 opening provides additional forming clearance for thicker sheet material and larger bend radii.

In many general sheet metal applications, a V20 opening can be used for bending sheet thicknesses around 2.5 mm, although the final V-opening should always be selected according to the material grade, tensile strength, required inside radius, flange geometry and bending method.

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

The V12 / V20 configuration shown here is one available example. Other V-opening combinations, die angles, overall dimensions, load capacities and mounting structures can be customized according to customer requirements.

V12 / V20 Double-V Configuration

The illustrated lower die combines a 12 mm V-opening and a 20 mm V-opening within one compact tool body.

Compared with smaller double-V combinations, the V20 groove offers increased forming clearance and is better suited to thicker sheet bending or applications requiring a larger inside bend radius.

The appropriate V-opening should be selected according to:

• Sheet thickness
• Material grade
• Tensile strength
• Desired inside bend radius
• Bend angle
• Flange dimension
• Forming force
• Bending method

The V12 / V20 combination shown here is only one available configuration.

Other V-opening combinations can be manufactured according to the customer's actual production requirements.

Typical Applications

This V12 / V20 double-V press brake die is suitable for:

• General sheet metal bending
• Thin and medium-thickness sheet fabrication
• Carbon steel bending
• Stainless steel bending
• Electrical enclosure production
• Metal cabinet manufacturing
• Machine cover fabrication
• Equipment housing production
• Mixed sheet thickness production
• Applications requiring both medium and larger V-openings
• Bending applications using approximately 2.5 mm sheet with the V20 groove, depending on material and forming conditions

V20 Groove for Thicker Sheet Bending

The V20 opening provides greater die clearance than V12, V16 or other smaller V-openings.

This makes it suitable for applications requiring:

• Thicker sheet material
• Larger natural inside bend radius
• Lower forming pressure compared with a smaller V-opening under otherwise similar conditions
• Increased workpiece clearance during bending

For many common sheet metal applications, the V20 groove can be used with approximately 2.5 mm sheet thickness.

However, the final die selection should be determined from the actual workpiece, material properties and bending requirements rather than sheet thickness alone.

Plug-In Lower Die Mounting System

The illustrated product uses a plug-in mounting configuration.

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

The plug-in structure shown here represents one reference configuration only.

WYS Machinery can customize the mounting profile according to:

• Press brake model
• Existing tooling system
• Lower die holder
• Existing tooling drawing
• Tooling sample
• Required mounting dimensions

The entire lower die cross-section can therefore be adapted to the customer's equipment.

Custom Double-V Press Brake Dies

WYS Machinery manufactures both standard and customized double-V press brake dies for different sheet metal bending applications.

The V12 / V20 die shown on this page is one manufactured configuration rather than a fixed product limitation.

Customers can customize:

V-opening combinations, die angles, overall height, overall width, shoulder geometry, V-bottom geometry, load capacity, tool length, segmented length, bottom profile and mounting interface.

For special applications, customers can provide:

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

Our engineering team can evaluate the bending requirement and recommend an appropriate 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 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 dimensions and plug-in profile shown on this page are therefore reference specifications only.

The V-opening, die angle, height, width and complete mounting structure can all be redesigned according to the customer's machine and tooling interface.
