V80 60° Stepped-Base Single-V Press Brake Lower Die – H110 × W110 mm, 100 Ton/m
This V80 60° stepped-base single-V press brake lower die features an 80 mm V-opening, 60° die angle, 110 mm overall height and 110 mm main body width, with a 60 mm bottom mounting base and 20 mm stepped 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, overall height, body width, bottom base dimensions, groove radii, tool length and mounting interface can all be customized according to the customer's press brake and bending requirements.

Description
V80 60° Stepped-Base Single-V Press Brake Lower Die
This V80 60° press brake lower die combines a large 80 mm V-opening with a 60° acute-angle single-V groove and a stepped mounting base, providing a robust lower-tool configuration for sheet metal bending applications requiring both acute-angle forming capability and increased forming clearance.
The illustrated configuration features:
V-Opening: V80 / 80 mm
Die Angle: 60°
Overall Height: 110 mm
Main Body Width: 110 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
Shoulder Radius: R8
V-Bottom Radius: R8
Rated Load Capacity: 100 ton/m
The 110 mm main tool body transitions to a 60 mm stepped mounting base, which is structurally different from conventional plug-in lower dies that use a narrow bottom shank.
The tooling shown represents one available configuration only. WYS Machinery can manufacture different V-openings, angles, heights, widths, radii, tool lengths and mounting structures according to customer requirements.
60° V-Groove for Acute-Angle Bending
The 60° single-V groove provides more angular clearance than conventional 85°, 88° or 90° lower dies.
This geometry is suitable for applications such as:
- Acute-angle air bending
- Pre-bending
- Multi-stage forming
- Intermediate-angle forming
- Precision flange bending
- Forming requiring springback allowance
- Customized sheet metal profiles
The actual bending result depends on the complete tooling combination and forming conditions, including the material grade, sheet thickness, punch geometry, V-opening, springback, required inside radius, flange dimensions and bending force.
V80 Opening for Large Forming Clearance
The 80 mm V-opening provides a large working zone and substantial clearance around the workpiece during bending.
Compared with smaller V-opening lower dies, the V80 configuration provides:
- Greater forming clearance
- A broader bending zone
- Increased space around the workpiece
- Suitability for larger expected bend radii
- More flexibility for larger sheet and flange geometry
The correct V-opening should always be selected according to the material type, sheet thickness, desired bend radius, flange size and bending-force requirements.
Stepped-Base Mounting Structure
A key characteristic of this lower die is the stepped-base mounting profile.
The illustrated dimensions are:
Main Body Width: 110 mm
Bottom Base Width: 60 mm
Step Height: 20 mm
This differs from a plug-in lower die, where a relatively narrow bottom shank is inserted into a corresponding lower-die holder.
The stepped-base design provides a wider working body combined with a defined mounting section underneath.
The body width, base width, step height, positioning geometry and complete mounting cross-section can all be customized according to the customer's machine and lower-die holder.
R8 Shoulder and V-Bottom Radii
The illustrated V80 groove uses:
Shoulder Radius: R8
V-Bottom Radius: R8
These radii form part of the working groove profile and can also be customized according to the V-opening, sheet thickness, material and required forming geometry.

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 V80 opening and 60° groove are not fixed limitations.
Different V-openings and die angles can be manufactured according to:
- Material grade
- Sheet thickness
- Required bending angle
- Desired inside radius
- Minimum flange dimension
- Material springback
- Required forming clearance
- Required bending force
- Press brake configuration
This allows the lower die to be designed around the customer's actual workpiece rather than limiting the application to a fixed catalog profile.
