Typical Applications

This TRUMPF Type V12 84° single-V lower die is suitable for general precision sheet metal bending where a compact but stable lower-die configuration is required.

Typical applications include:

• Precision sheet metal bending
• Light-to-medium sheet metal fabrication
• Cabinet and enclosure manufacturing
• Electrical cabinet components
• Machinery covers and panels
• HVAC sheet metal parts
• Metal furniture components
• General industrial fabrication
• Small and medium sheet metal components
• Repeated CNC press brake production
• Applications requiring a moderate V-opening
• Controlled air-bending operations

The V12 opening provides a useful middle position between very small V openings such as V4 or V8 and larger openings such as V16 or V20.

V12 Opening for Balanced General Bending

The V12 opening is the main forming characteristic of this lower die.

In air bending, the V-opening affects:

• Required bending force
• Inside bend radius
• Minimum flange length
• Material support
• Final bend geometry
• Tooling load

Compared with V8 or V10, V12 provides more forming space and can be more suitable for slightly thicker material or applications requiring a somewhat larger inside radius.

Compared with V16 or larger dies, it still maintains a relatively compact geometry suitable for precision bending and smaller components.

This makes V12 a practical choice for customers who require a balanced small-to-medium V-opening for general press brake production.

84° Die Angle for Controlled Forming

This lower die uses an 84° V angle, providing a slightly more acute geometry than common 86° or 88° lower dies.

This can be useful in applications where:

• Material springback needs to be considered
• Controlled overbending is required
• A precise final angle is important
• The bending process requires additional angular flexibility

The actual finished angle depends on the complete tooling combination and forming conditions, including:

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

For this reason, the 84° V12 die should be selected together with the appropriate upper punch and required final workpiece geometry.

---

25 mm Width for a Stable Lower-Die Structure

This model has a 25 mm overall width, providing a stable and practical lower-tool body.

Compared with extremely narrow clearance dies, this structure is designed more for general bending stability and versatility than for maximum workpiece avoidance.

The 25 mm body width provides:

• Stable support around the V-opening
• Practical tooling strength
• Good suitability for general production
• Balanced dimensions for CNC press brake use

This differentiates it from the narrower V12 / 86° model, where the reduced working width is specifically intended to provide workpiece clearance.

---

50 Ton/m Load Capacity

This lower die has a rated maximum load capacity of 50 ton/m.

The required bending force depends on:

• Material type
• Material thickness
• Material tensile strength
• Bending length
• V-opening
• Punch geometry
• Required bending angle
• Bending method

The actual forming force must remain within the rated capacity of the:

• Upper punch
• Lower die
• Press brake machine

For higher-force applications, larger V-openings or reinforced tooling structures can be designed according to the customer's requirements.

---

Product Details & Manufacturing Quality

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

The V-opening and critical working surfaces are precision machined to help maintain:

• Accurate V geometry
• Stable material support
• Consistent tool alignment
• Repeatable bending performance

For a V12 die, dimensional accuracy is important because the V-opening directly affects bending force, inside radius, and finished workpiece geometry.

The combination of:

V12 Opening + 84° Angle + 25 mm Width + 50 Ton/m Capacity

makes this model a practical lower die for precision and general light-to-medium sheet metal bending.

Free Tooling Design for V-Opening Selection

Selecting the correct lower die should be based on the actual workpiece rather than V-opening alone.

WYS Machinery can evaluate:

Material Thickness
→ Required Inside Radius
→ Minimum Flange Length
→ Required Bending Force
→ Punch Geometry
→ V-Opening Selection
→ Final Tooling Combination

This helps customers determine whether V8, V10, V12, V16, or another V-opening is more suitable for the intended bending process.
