V80 85° Stepped-Base Single-V Press Brake Lower Die – H80 × W95 mm, 100 Ton/m
This V80 85° stepped-base single-V press brake lower die features an 80 mm V-opening, 85° die angle, 80 mm overall height and 95 mm main body width, with a 60 mm bottom base width and 20 mm stepped mounting section. The rated load capacity is 100 ton/m. Unlike conventional plug-in single-V lower dies, this model uses a stepped-base mounting structure rather than a narrow plug-in shank. The V-opening, die angle, tool height, body width, base width, step height, groove radius, tool length and mounting interface can all be customized according to the customer's press brake and bending requirements.

Description
V80 85° Stepped-Base Single-V Press Brake Lower Die
This V80 85° press brake lower die combines a large single-V working groove with a stepped lower mounting structure, providing a robust lower-tool configuration for sheet metal air-bending applications requiring a large V-opening and substantial forming clearance.
The illustrated model features:
V-Opening: V80 / 80 mm
Die Angle: 85°
Overall Height: 80 mm
Main Body Width: 95 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
Shoulder Radius: R6
V-Bottom Radius: R5
Rated Load Capacity: 100 ton/m
The lower mounting profile differs from the narrow plug-in configuration used on many other single-V dies. In this design, the 95 mm main body transitions to a 60 mm wide stepped base, providing a distinctive lower-tool mounting geometry.
The tooling shown on this page represents one available configuration only. WYS Machinery can manufacture the complete lower-die cross-section according to the customer's machine, die holder and workpiece requirements.
V80 Opening for Large Forming Clearance
The 80 mm V-opening provides a large forming zone and substantial workpiece clearance during bending.
Compared with smaller V-opening dies, the V80 configuration provides:
- Greater forming clearance
- A broader working zone
- More space around the workpiece
- Suitability for applications requiring a larger expected bend radius
- More flexibility for heavier or larger sheet-metal components, subject to actual bending-force requirements
The appropriate V-opening should be selected according to the material grade, sheet thickness, required inside radius, minimum flange dimension and bending force.
85° V-Groove for Precision Air Bending
The illustrated model uses an 85° single-V groove.
This geometry is suitable for precision air-bending applications where some angular allowance may be required to compensate for material springback.
The final bend result depends on multiple factors, including:
- Material type
- Sheet thickness
- Punch angle
- V-opening
- Material springback
- Inside bend radius
- Flange dimensions
- Required bending force
The 85° angle shown here is one available configuration. Other die angles can also be manufactured according to the customer's actual forming process.
Stepped-Base Mounting Structure
A key feature of this lower die is its stepped-base mounting structure.
The illustrated geometry includes:
Main Body Width: 95 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
This differs from a typical plug-in lower die, which uses a narrower bottom mounting shank inserted into a corresponding die holder.
The stepped-base design provides a wider and more substantial lower-tool body while retaining a narrower mounting base.
The base width, step height, body width and positioning geometry can all be customized according to the customer's machine and die-holder requirements.
R6 Shoulder Radius and R5 V-Bottom Radius
The illustrated V80 groove includes two clearly defined radius features:
Shoulder Radius: R6
V-Bottom Radius: R5
These radii form part of the working geometry around the V-groove and can be adjusted according to the required forming process.
The groove radius, shoulder radius and edge geometry are not limited to the dimensions shown.
