Typical Applications

This TRUMPF Type V40 80° lower die is designed for applications requiring more forming space and higher tooling capacity than medium V-opening dies.

Typical applications include:

• Thicker sheet metal bending
• Industrial plate bending
• Machinery components
• Equipment frames and panels
• Structural sheet metal parts
• Fabricated steel components
• Applications requiring a larger inside bend radius
• Applications where smaller V-openings would require excessive bending force
• High-load CNC press brake production

Compared with V24 or V30 tooling, the V40 opening provides a larger forming zone and generally reduces the required bending force for the same material thickness.

V40 Opening for Thicker Material and Larger Bend Radii

The V40 opening is the main functional characteristic of this die.

Compared with smaller V-openings such as V16, V24, or V30, V40 provides:

• More forming space
• Lower required bending force for the same material thickness
• A larger achievable inside bend radius
• Better suitability for thicker sheet and plate
• More flexibility for industrial bending applications

V40 therefore serves as an important transition between medium V-opening tooling and the very large V dies used for heavy-plate applications.

The final V-opening selection should always consider material thickness, material strength, required inside radius, minimum flange length, punch geometry, and press brake capacity.

80° Geometry with 120 Ton/m Capacity

The 80° die angle provides additional angular range for springback compensation and controlled overbending compared with less acute lower dies.

At the same time, the die has a rated load capacity of 120 ton/m, giving it substantially higher load-bearing capability than lighter V30 and smaller-V tooling.

The combination of:

V40 Opening + 80° Angle + 55 mm Width + 120 Ton/m Capacity

makes this model suitable for demanding industrial applications where both a larger V-opening and higher tooling strength are required.

Actual working force must remain within the rated capacity of the upper punch, lower die, press brake machine, and clamping system.

Product Details & Manufacturing Quality

The lower die is manufactured from 42CrMo alloy steel, providing high strength, toughness, and durability for repeated press brake operations.

Critical working surfaces, including the V-opening, locating areas, and mounting sections, are precision machined to maintain consistent tooling geometry and stable bending performance.

The 55 mm body width provides substantial structural support around the V40 opening, helping the die withstand its rated 120 ton/m load capacity.
