V4 / V7 85° Double-V Press Brake Lower Die

This double-V press brake lower die integrates V4 and V7 openings into a single compact die body, with both V-grooves manufactured at an 85° angle.

The die measures 50 mm in overall width and 26 mm in overall height, with a rated load capacity of 70 ton/m. Its two adjacent V-openings provide two bending groove options within one lower die, making it suitable for production environments where different V-opening sizes are required while maintaining a compact tooling configuration.

The illustrated version uses a plug-in mounting system, allowing the lower die to be positioned securely in a compatible lower die holder or press brake table system.

Rather than requiring two completely separate single-V dies, the double-V configuration integrates two working grooves into the same die body. The appropriate V-opening can be selected according to the material, sheet thickness, required bend geometry and production setup.

Double-V Die Configuration

The V4 / V7 combination shown on this product is one example of a double-V die configuration.

Different combinations can be manufactured according to the customer's sheet thickness range, bending radius, material properties and production requirements.

Available customization can include:

• V-opening size
• Combination of two V-openings
• V-groove angle
• Overall die height
• Overall die width
• Shoulder geometry
• V-bottom geometry
• Tool length
• Segmented length
• Bottom mounting profile
• Positioning structure
• Plug-in interface
• Complete lower-die cross-section

This allows the same double-V tooling concept to be adapted to different bending applications rather than being limited to the V4 / V7 configuration shown here.

Typical Applications

This double-V press brake die is suitable for:

• Thin sheet metal bending
• General precision sheet metal fabrication
• Small V-opening bending applications
• Production requiring more than one V-opening size
• Electrical enclosure manufacturing
• Metal cabinet and panel production
• Equipment housing fabrication
• Stainless steel and carbon steel sheet bending
• Small-batch and mixed-production bending
• Applications where reducing lower-die changes can improve production efficiency

The actual V-opening should always be selected according to the material thickness, material strength, required inside radius and bending method.

Plug-In Lower Die System

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

This structure allows the lower die to engage with a corresponding die holder or lower tooling interface while maintaining accurate positioning during bending.

The plug-in structure shown here is not the only available mounting option. The bottom geometry and mounting interface can be manufactured according to the customer's existing press brake, lower die holder or tooling system.

Custom Double-V Press Brake Dies

WYS Machinery manufactures custom double-V press brake dies based on customer drawings, bending parts and machine specifications.

The displayed V4 / V7 die represents one available configuration rather than a fixed product limitation.

Customers can specify different:

V-openings, die angles, overall heights, widths, lengths, load requirements, mounting profiles and positioning structures.

If the required tooling geometry is not available as a standard model, customers can provide the bending part drawing or tooling dimensions. Our engineering team can develop a suitable lower-die configuration according to the actual bending application.

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 tooling configurations include:

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

The plug-in mounting structure shown in this product drawing is therefore one reference configuration only. The mounting interface and complete die cross-section can be redesigned according to the customer's press brake.

Standard & Custom Lower Die Solutions

In addition to double-V dies, WYS Machinery manufactures a broad range of press brake lower tooling, including:

Single-V Dies · Double-V Dies · Multi-V Dies · Acute-Angle Dies · Wide-Opening Dies · High-Tonnage Dies · Special Lower Dies · Custom Press Brake Tooling

This enables the lower tooling configuration to be selected according to the actual bending process rather than restricting production to a fixed standard die design.
