V50 45° Stepped-Base Single-V Press Brake Lower Die – H80 × W85 mm, 100 Ton/m
This V50 45° stepped-base single-V press brake lower die features a 50 mm V-opening, 45° die angle, 80 mm overall height and 85 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
V50 45° Stepped-Base Single-V Press Brake Lower Die
This V50 45° press brake lower die combines a 50 mm V-opening with an acute 45° single-V groove and a stepped lower mounting structure, providing a robust tooling configuration for acute-angle air bending, pre-bending and multi-stage sheet metal forming.
The illustrated configuration features:
V-Opening: V50 / 50 mm
Die Angle: 45°
Overall Height: 80 mm
Main Body Width: 85 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
Shoulder Radius: R5
V-Bottom Radius: R6
Rated Load Capacity: 100 ton/m
The wider 85 mm main body transitions to a 60 mm stepped bottom base, which is structurally different from plug-in lower dies that use a narrow mounting shank beneath the main tool body.
The dimensions shown represent one available configuration rather than fixed manufacturing limitations. WYS Machinery can manufacture different V-openings, angles, heights, body widths, base dimensions, groove radii, tooling lengths and mounting structures according to customer requirements.
45° V-Groove for Acute-Angle Bending
The illustrated lower die uses a 45° single-V groove, providing considerably more angular clearance than conventional 85°, 88° or 90° lower dies.
This geometry can be suitable for:
- Acute-angle air bending
- Pre-bending
- Multi-stage forming
- Precision flange bending
- Intermediate-angle forming
- Forming requiring additional angular allowance
- Customized sheet metal profiles
The actual bending result depends on the material grade, sheet thickness, punch geometry, V-opening, required inside radius, flange dimensions, springback and bending force.
V50 Opening for Increased Forming Clearance
The 50 mm V-opening provides increased forming clearance compared with smaller V-opening dies such as V32 or V40.
This larger opening can be useful when the application requires:
- A broader forming zone
- Increased clearance around the workpiece
- A larger expected inside bend radius
- Larger flange geometry
- More forming space during acute-angle bending
The correct V-opening should be selected according to the actual material and forming process rather than V-opening alone.
Stepped-Base Mounting Structure
A key characteristic of this lower die is its stepped-base mounting profile.
The illustrated structure includes:
Main Body Width: 85 mm
Bottom Base Width: 60 mm
Step Height: 20 mm
This differs from a plug-in lower die, which normally uses a narrow mounting shank inserted into a corresponding lower-die holder.
The stepped-base structure provides a broader supporting profile while maintaining a defined lower mounting section.
The body width, base width, step height, positioning geometry and complete mounting profile can all be customized to match the customer's press brake or existing tooling system.
R5 Shoulder Radius and R6 V-Bottom Radius
The illustrated V50 profile includes:
Shoulder Radius: R5
V-Bottom Radius: R6
These radii form part of the working groove geometry and can also be modified according to the V-opening, material, sheet thickness and required forming result.

The bottom mounting profile, base width, step height, overall height, body width and complete die cross-section can all be adapted according to the customer's press brake.
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 V50 opening and 45° groove are not fixed limitations.
Different V-openings and die angles can be manufactured according to:
- Material type
- 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 actual workpiece rather than requiring customers to select only from fixed catalog dimensions.
