Typical Applications

This TRUMPF Type V16 single-V lower die is designed for general CNC press brake bending applications requiring a medium-size V-opening and stable tooling support.

Typical applications include:

• General sheet metal bending
• Precision air bending
• Cabinet and enclosure manufacturing
• Machinery components
• Industrial equipment panels
• Electrical cabinet parts
• HVAC sheet metal fabrication
• Metal furniture components
• Structural sheet metal parts
• Repeated CNC press brake production
• Medium V-opening bending applications
• Customized sheet metal fabrication

The V16 opening makes this lower die suitable for applications where a smaller V-opening such as V6 or V8 may be too narrow, while much larger V-openings would be unnecessary for the required material and bend geometry.

Actual material thickness suitability should always be determined together with material grade, required inside radius, upper punch geometry, bending angle, and press brake capacity.

V16 Opening for General Sheet Metal Bending

The V16 opening is the main functional characteristic of this lower die.

In air bending, the V-opening strongly affects:

• Required bending force
• Resulting inside bend radius
• Material support
• Minimum flange length
• Bending accuracy
• Tooling load

A V16 lower die can provide a useful balance between forming accessibility, bending force, and material support for many general fabrication applications.

The final tooling selection should not be based on V-opening alone. Material thickness, material tensile strength, required radius, punch tip geometry, and final bending angle should all be considered together.

For customers who are unsure whether V16 is suitable, our engineering team can evaluate the workpiece drawing and recommend an appropriate punch-and-die combination.

---

86° Die Angle for Precision Bending

This die uses an 86° V angle, making it suitable for common precision air-bending applications.

The slightly acute die geometry provides process flexibility when forming parts where material springback must be considered.

The actual finished angle depends on:

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

For this reason, the 86° lower die should be considered as part of a complete bending system rather than evaluated independently.

---

100 mm Working Height with Stable Tool Structure

The die has a 120 mm overall height and 100 mm working height.

This provides a relatively substantial lower-tool structure while maintaining a practical profile for industrial press brake applications.

The 30 mm overall width creates a compact lower die configuration suitable for applications where excessive die width is unnecessary.

The combination of:

V16 Opening + 86° Angle + 100 mm Working Height + 70 Ton/m Capacity

provides a balanced lower die for general industrial sheet metal bending.

---

70 Ton/m Load Capacity

This model has a rated load capacity of 70 ton/m.

The actual allowable bending operation must consider both the tooling load capacity and the machine capacity.

Important factors include:

• Material type
• Sheet thickness
• Bending length
• Material tensile strength
• V-opening
• Punch tip radius
• Required angle
• Press brake tonnage

The required bending force should remain within the rated capacity of the die, upper punch, and press brake machine.

For higher-force or thicker-plate applications, WYS Machinery can also design larger V-openings and reinforced lower-die structures 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
• Consistent tool alignment
• Stable material support
• Repeatable bending performance

The V16 opening and 86° working angle are manufactured according to the specified tooling geometry.

Correct lower-die geometry is especially important because dimensional variation in the V-opening or die angle can directly influence bending force, final bend radius, and repeatability.

Free Press Brake Tooling Design Support

Selecting the correct V-opening is only one part of a successful bending process.

For new or special workpieces, WYS Machinery can evaluate:

Workpiece Drawing
→ Material & Thickness
→ Required Radius & Angle
→ Bending Force
→ Punch Selection
→ Lower Die Selection
→ Tooling Configuration

Our goal is not simply to supply a V16 lower die, but to recommend a tooling combination that matches the customer's actual bending requirements.

This is particularly useful for customers working with new materials, unusual profiles, tight tolerances, or customized press brake tooling systems.
