V160 80° Stepped-Base Single-V Press Brake Lower Die – H150 × W200 mm, 100 Ton/m
This V160 80° stepped-base single-V press brake lower die features a 160 mm V-opening, 80° die angle, 150 mm overall height and 200 mm main body width, with a 90 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, overall height, body width, bottom base width, groove radii, tool length and mounting interface can all be customized according to the customer's press brake and bending requirements.

Description
V160 80° Stepped-Base Single-V Press Brake Lower Die
This V160 80° press brake lower die combines a very large single-V working groove with a stepped lower mounting structure, providing a robust lower-tool configuration for sheet metal bending applications requiring substantial forming clearance.
The illustrated configuration features:
V-Opening: V160 / 160 mm
Die Angle: 80°
Overall Height: 150 mm
Main Body Width: 200 mm
Bottom Base Width: 90 mm
Stepped Section Height: 20 mm
Shoulder Radius: R16
V-Bottom Radius: R22
Rated Load Capacity: 100 ton/m
The lower mounting profile differs from the narrow plug-in mounting structure used on many standard single-V dies. In this design, the 200 mm main body transitions to a 90 mm stepped bottom base, creating a distinct mounting geometry for compatible press brake die holders and lower-tool systems.
The dimensions shown represent one available configuration only. WYS Machinery can manufacture different V-openings, die angles, heights, widths, radii, tool lengths and mounting profiles according to customer requirements.
V160 Opening for Very Large Forming Clearance
The 160 mm V-opening provides a very large working zone and substantial clearance around the sheet during bending.
Compared with smaller V-opening lower dies, the V160 configuration provides more forming space and can be suitable for applications requiring:
- Very large V-opening air bending
- Greater workpiece clearance
- Larger expected inside bend radii
- Broader flange geometry
- Larger sheet metal sections
- Heavy-duty forming applications requiring more die opening space
The correct V-opening should always be selected according to the material grade, sheet thickness, required bend radius, flange dimensions and bending force.
80° V-Groove for Custom-Angle Air Bending
The illustrated lower die uses an 80° single-V groove.
Compared with wider-angle lower dies such as 85°, 88° or 90°, the 80° geometry provides additional angular clearance and can be used in applications where a more acute lower-die angle is required.
The actual final bend angle depends on factors such as:
- Material grade
- Sheet thickness
- Punch geometry
- V-opening
- Material springback
- Required inside radius
- Minimum flange dimension
- Required bending force
The illustrated 80° groove is one available specification only. Different die angles can also be manufactured according to the customer's forming process.
Stepped-Base Mounting Structure
A key structural feature of this lower die is its stepped-base mounting profile.
The illustrated geometry includes:
Main Body Width: 200 mm
Bottom Base Width: 90 mm
Step Height: 20 mm
This differs from a plug-in lower die, which typically uses a relatively narrow bottom mounting shank beneath the main tool body.
The stepped-base design combines a very wide main working body with a narrower mounting base and can be adapted according to the customer's machine interface, die holder and existing tooling arrangement.
The base width, step height, body width, positioning geometry and complete die cross-section can all be customized.
R16 Shoulder Radius and R22 V-Bottom Radius
The illustrated V160 lower die includes two clearly defined radius features:
Shoulder Radius: R16
V-Bottom Radius: R22
These radii form part of the working groove geometry and can also be customized according to the V-opening, sheet thickness, material and required bend geometry.

Customers can provide a machine model, existing lower-die drawing, die-holder dimensions, tooling cross-section, tooling sample or workpiece drawing for technical evaluation.
Custom V-Opening and Die Angle
The V160 opening and 80° groove shown here are one available specification rather than fixed limitations.

- Material grade
- Sheet thickness
- Required bending angle
- Desired inside radius
- Minimum flange dimension
- Material springback
- Required forming clearance
- Required bending force
