Typical Applications

This TRUMPF Type V12 narrow single-V lower die is designed for applications where the lower tooling must provide not only the required V-opening, but also additional clearance around the workpiece.

Typical applications include:

• Precision sheet metal bending
• Small and medium sheet metal components
• Parts with nearby flanges
• Previously formed workpieces
• Narrow channel components
• Box and enclosure parts
• Components with limited space around the bend line
• Multi-step bending
• Cabinet and electrical enclosure fabrication
• Machinery covers and panels
• General CNC press brake production
• Applications where a wider lower die may cause interference

The combination of a V12 opening and 16 mm narrow load-bearing section makes this die particularly useful when tooling clearance is an important part of the bending process.

Narrow 16 mm Load-Bearing Width for Better Clearance

The key structural characteristic of this model is its 16 mm load-bearing width.

Compared with wider lower dies, the narrow working section leaves more space around the tooling body.

This can be useful when the workpiece has:

• Nearby return flanges
• Previously formed sections
• Narrow channels
• Closely spaced bending lines
• Limited internal space
• Complex surrounding geometry

During multi-step bending, a wider lower die body may interfere with already formed sections of the workpiece.

The narrower structure can help:

• Reduce tool-to-workpiece interference
• Improve access around the bend line
• Increase lower-tool clearance
• Accommodate more compact workpiece geometries
• Provide greater flexibility in bending sequences

For this reason, this model should be considered not only as a V12 lower die, but also as a clearance-oriented narrow press brake die.

V12 Opening for Precision Bending

The V12 opening provides a smaller opening than the V16 model and is suitable for applications requiring tighter lower-tool geometry.

In air bending, the V-opening directly affects:

• Required bending force
• Resulting inside bend radius
• Minimum flange length
• Workpiece support
• Bending accuracy

Compared with larger V-openings, V12 can be useful when customers require a more compact die geometry or are working with thinner material and smaller flange dimensions.

However, the correct V-opening should always be selected according to:

• Material type
• Material thickness
• Required inside radius
• Punch tip radius
• Bending angle
• Required bending force
• Machine capacity

WYS Machinery can evaluate the workpiece drawing and recommend the appropriate upper and lower tooling combination.

---

86° Die Angle for Controlled Bending

This lower die uses an 86° V angle.

The slightly acute die geometry provides flexibility for precision air-bending applications where material springback must be considered.

The actual finished angle depends on the complete bending process, including:

• Punch angle
• Punch radius
• Material type
• Sheet thickness
• Material springback
• V-opening
• Applied force
• Press brake settings

For this reason, the 86° die should be selected as part of a complete punch-and-die system rather than considered independently.

---

55 Ton/m Load Capacity

This model has a rated load capacity of 55 ton/m.

Because the working section is relatively narrow, correct bending-force evaluation is especially important.

The required force depends on:

• Material strength
• Sheet thickness
• Bending length
• V-opening
• Bending method
• Punch geometry
• Required final angle

The actual working force must remain within the load capacity of the upper punch, lower die, and press brake machine.

If the application requires higher bending force, WYS Machinery can also design wider or reinforced lower-die structures while maintaining the required V-opening and mounting configuration.

---

Product Details & Manufacturing Quality

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

The V-opening, working edges, locating surfaces, and mounting areas are precision machined to maintain dimensional consistency.

For this model, particular attention is given to the relationship between:

V12 Opening + 16 mm Narrow Working Section + 55 Ton/m Capacity

because the tool must provide useful workpiece clearance while still maintaining sufficient structural strength for the specified application.

The result is a lower die specifically suited to customers who need a compact lower tooling profile rather than simply a standard-width V-die.

Free Tooling Design for Workpiece Clearance Problems

For clearance-related applications, selecting the V-opening alone is often not enough.

A workpiece may require the correct V-opening but still be impossible to bend if the surrounding lower-die body interferes with an existing flange or previously formed section.

For these applications, WYS Machinery can evaluate:

Workpiece Geometry
→ Bending Sequence
→ Interference Area
→ Required V-Opening
→ Required Die Width
→ Tooling Strength
→ Final Custom Die Design

This allows us to design the lower die according to the customer's actual workpiece rather than forcing the workpiece to fit a standard die profile.
