Typical Applications

This TRUMPF Type 28° R1 tall acute angle punch is designed for applications requiring both acute-angle forming capability and increased working height.

Typical applications include:

• Large-size sheet metal components
• Acute-angle sheet metal bending
• Pre-bending operations
• Small-angle forming
• Sharp-angle bending
• Large machinery components
• Industrial equipment components
• Deep profile bending
• High-profile workpiece bending
• Large cabinet and enclosure components
• Structural sheet metal parts
• Special profile forming
• Multi-step bending
• Hemming preparation
• Large components with previously formed sections
• Complex sheet metal forming
• CNC press brake production

Compared with a conventional-height acute-angle punch, the 220 mm effective height provides additional working reach for large and high-profile components.

For customers currently using TRUMPF original tooling or corresponding tooling systems, we can manufacture suitable TRUMPF Type tooling solutions according to existing tooling dimensions, machine specifications, and actual workpiece requirements.

220 mm Tall Structure for Large Workpieces

One of the most important characteristics of this model is its 220 mm effective height.

For large sheet metal components, the overall geometry of the workpiece can sometimes become a limitation during the bending process. Large side walls, existing flanges, deep profiles, or previously formed sections may require additional space around the upper tool.

The tall tooling structure provides increased working reach and can help accommodate:

• Large workpieces
• High side walls
• Deep profiles
• Large existing flanges
• Previously formed sections
• Large machinery components
• Complex multi-step parts
• High-profile sheet metal structures

Compared with the 120 mm version of the 28° acute-angle punch, this 220 mm model is particularly suitable for applications where additional tooling height is required to process larger workpieces.

This gives the model a clear application advantage for large industrial components.

28° Acute Angle for Pre-Bending and Special Forming

The second defining characteristic of this punch is its 28° acute working angle.

Compared with conventional 85°, 86°, 88°, or 90° upper tooling, the significantly sharper geometry provides additional forming capability for specialized bending processes.

Typical uses include:

• Acute-angle bending
• Small-angle forming
• Pre-bending
• Overbending
• Special profile forming
• Multi-stage forming
• Hemming preparation

In some manufacturing processes, the workpiece must first be formed to an acute angle before undergoing another bending or flattening operation.

The 28° punch angle provides the required geometry for these specialized bending sequences.

Actual finished bending angle depends on material type, material thickness, lower die geometry, springback, bending method, and machine settings.

Tall Tooling Structure with 60 Ton/m Capacity

Increasing tooling height can create additional structural demands on an upper punch.

For this reason, this model uses a relatively substantial 60 mm overall width, providing a robust body for the tall 220 mm tooling structure.

The combination of:

220 mm Height + 60 mm Width + 60 Ton/m Capacity

provides a practical balance between:

Increased Working Reach + Large Workpiece Capability + Tooling Strength

The rated 60 ton/m load capacity makes the punch suitable for a wide range of industrial acute-angle forming applications within the specified working limits.

Actual allowable bending force should always be evaluated according to material type, sheet thickness, bending length, lower die opening, bending method, workpiece geometry, and press brake specifications.

---

R1 Tip Radius for Precise Acute-Angle Forming

The R1 tip radius complements the sharp 28° punch geometry and provides a defined working profile for precision forming.

This geometry can be suitable for:

• Precise bending lines
• Acute-angle bending
• Small-radius applications
• Pre-bending
• Controlled overbending
• Special sheet metal profiles
• Repeatable CNC forming

The final workpiece radius is influenced by the complete bending process, including material thickness, material properties, die opening, bending method, and springback.

For special applications, our engineering team can evaluate the workpiece drawing and recommend an appropriate upper punch and lower die combination.

Product Details & Manufacturing Quality

The upper punch is manufactured from 42CrMo alloy steel, providing high strength, toughness, wear resistance, and durability for repeated industrial press brake operations.

The working area is heat treated to approximately HRC 54 ± 2, helping maintain dimensional stability and wear resistance during continuous production.

Precision machining is applied to critical working surfaces to maintain the specified 28° punch angle and R1 tip radius.

The 220 mm effective height is the key structural characteristic of this model, providing increased working reach for large and high-profile workpieces.

Its 60 mm overall width provides a substantial tooling body to support the tall structure, while the rated 60 ton/m load capacity provides sufficient strength for a wide range of industrial applications.

The combination of:

28° Acute Angle + R1 Tip + 220 mm Tall Structure + 60 Ton/m Capacity

makes this model particularly suitable for large-workpiece acute-angle bending and specialized forming applications.

Standard & Fully Customizable TRUMPF Type Press Brake Tooling

We manufacture both standard TRUMPF Type press brake tooling and fully customized tooling solutions.

All of our press brake tooling can be customized according to the customer's machine, workpiece geometry, material, bending process, and production requirements.

Customers can send us:

• 2D workpiece drawings
• 3D models
• Bending drawings
• Existing tooling drawings
• Press brake machine specifications
• Photos and dimensions of existing tooling
• Workpiece samples

Our engineering team provides a free press brake tooling design service. Customers can simply send us their workpiece drawings and bending requirements, and we can help design a suitable tooling solution.

Customization options include:

• Punch angle
• Tip radius
• Effective tooling height
• Overall tooling width
• Working section dimensions
• Tooling length
• Segmented tooling lengths
• Special clearance geometry
• Relief structures
• Interference-avoidance structures
• Reinforced tooling structures

• Customized upper punches
• Customized lower dies
• Complete customized upper and lower tooling sets

For large and complex components, we can also evaluate workpiece clearance, bending sequence, flange geometry, punch interference, required bending force, tooling strength, and machine configuration before production.

This enables us to design the tooling around the customer's actual workpiece and bending process, rather than requiring the customer to adapt their product to a standard tooling profile.

Custom TRUMPF Type Tooling for Large & Special Workpieces

Large workpieces and special bending applications often require more than a standard catalog tool.

The combination of a 220 mm effective height and 28° acute working angle makes this model particularly suitable for customers who require both increased tooling reach and specialized acute-angle forming capability.

For customers currently using TRUMPF original tooling or requiring corresponding tooling for their press brake systems, WYS Machinery can manufacture TRUMPF Type tooling according to machine and application requirements.

Whether the requirement involves a different height, width, punch angle, tip radius, working length, clearance profile, or completely special geometry, our engineering team can provide free tooling design assistance and customized manufacturing.
