Typical Applications

This TRUMPF Type 86° R1 gooseneck punch is designed for applications where a conventional straight upper punch may not provide sufficient clearance or accessibility.

Typical applications include:

• Small and narrow workpiece bending
• High-profile sheet metal components
• Box and channel bending
• U-shaped workpiece forming
• Cabinet and enclosure fabrication
• Electrical cabinet components
• Machinery covers and panels
• Previously formed flange bending
• Return flange bending
• Multi-step bending
• Complex sheet metal profiles
• Components requiring additional punch clearance
• Precision sheet metal fabrication
• CNC press brake production

The combination of a 5 mm narrow tip section, 160 mm effective height, and gooseneck profile allows this tool to handle a wider variety of workpiece geometries than a conventional straight punch.

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

5 mm Narrow Tip for Small Workpieces

One of the most important characteristics of this model is the 5 mm narrow working section near the punch tip.

Instead of maintaining a wide body all the way to the working tip, the lower portion of the punch is intentionally reduced in width.

This provides additional space immediately around the bending area.

The narrow profile can be particularly useful for:

• Small sheet metal components
• Narrow workpieces
• Small boxes and channels
• Components with limited internal space
• Workpieces with closely positioned bends
• Multi-step bending operations
• Parts where a wider punch would interfere with existing geometry

This gives the tool an important advantage over conventional wider gooseneck punches.

The design essentially combines:

Gooseneck Clearance + 5 mm Narrow Tip Accessibility

allowing the tool to work with smaller and more geometrically restricted components.

---

160 mm Effective Height for Higher Workpieces

Another important characteristic is the 160 mm effective height.

Compared with shorter standard upper punches, the increased tooling height provides additional working reach and space around the workpiece.

This can be useful when bending:

• Higher-profile workpieces
• Deeper sheet metal components
• Tall box structures
• Previously formed parts
• Components with longer flanges
• Complex multi-bend products

The increased height does not mean that every 160 mm-high workpiece can automatically be bent, because actual accessibility also depends on the workpiece geometry, machine stroke, lower die, bending sequence, and surrounding tooling clearance.

However, compared with a shorter punch of similar geometry, the 160 mm tooling height provides greater flexibility for higher and more complex components.

Gooseneck Clearance for Complex Bending

The gooseneck profile is one of the defining structural characteristics of this upper punch.

During multi-step bending, previously formed flanges can extend toward the upper tooling. With a conventional straight punch, these flanges may collide with the punch body before the next bend can be completed.

The recessed gooseneck profile creates additional clearance around the workpiece.

This can help accommodate:

• Previously formed flanges
• Return bends
• U-shaped components
• Box-shaped components
• Deep channels
• High side walls
• Complex sheet metal profiles
• Multi-step bending sequences

This makes gooseneck tooling particularly valuable for workpieces where tool-to-workpiece interference is one of the main limitations during the bending process.

Three Structural Advantages in One Punch

This model is particularly useful because it does not rely on only one clearance feature.

It combines three structural characteristics:

5 mm Narrow Tip
Provides additional accessibility close to the actual bending point.

160 mm Effective Height
Provides increased working reach for higher-profile components.

Gooseneck Profile
Provides clearance for previously formed flanges and complex workpiece geometry.

Together, these features provide:

Narrow Tip Access + Increased Working Height + Gooseneck Clearance

This makes the punch especially suitable for customers producing small but geometrically complex components, higher-profile parts, and workpieces requiring multiple bending operations.

---

43 Ton/m Load Capacity

Because the lower working section is intentionally narrowed to improve accessibility and the tool uses a gooseneck clearance profile, its structural characteristics differ from those of a heavy-duty straight punch.

This model has a rated maximum load capacity of 43 ton/m.

It is therefore particularly suited to applications where clearance and accessibility are more important than extremely high bending tonnage.

Actual allowable bending force should always be evaluated according to:

• Material type
• Material thickness
• Bending length
• Lower die opening
• Workpiece geometry
• Bending method
• Required bending force
• Press brake capacity
• Tooling configuration

The required bending force must remain within the rated capacity of both the tooling and press brake.

Button or Positioning Pin – Two Configurations Available

Our TRUMPF Type press brake tooling is available with two positioning/retention configurations: button or positioning pin.

Customers can select the appropriate configuration according to their existing tooling system, press brake configuration, operating requirements, and tooling preferences.

Available options include:

• Button configuration
• Positioning pin configuration

When ordering, customers can provide their existing tooling drawing, machine information, or photos of the current tool interface, and we can manufacture the corresponding configuration.

This option is available not only for this gooseneck punch but also for our other TRUMPF Type press brake tooling.

Product Details & Manufacturing Quality

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

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

Precision machining is applied to critical working surfaces to maintain the specified 86° punch angle and R1 tip radius.

Particular attention is given to the geometry of the gooseneck profile and narrow working section, because these areas determine the actual workpiece clearance and accessibility.

The combination of:

86° + R1 + 5 mm Narrow Tip + 160 mm Height + Gooseneck Clearance

creates a specialized upper punch for applications where conventional straight tooling may have difficulty accessing the required bending position.

Standard & Fully Customizable TRUMPF Type Gooseneck Tooling

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

All WYS press brake tooling can be customized according to the customer's machine, workpiece, material, bending sequence, and production requirements.

Customers can provide:

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

Our engineering team provides a free press brake tooling design service.

For complex workpieces, customers can simply send us the finished product drawing. We can analyze the bending sequence, flange dimensions, potential interference areas, required clearance, tooling strength, and machine configuration and then recommend an appropriate tooling solution.

Customization options include:

• Punch angle
• Tip radius
• Tip width
• Narrow working section width
• Effective tooling height
• Overall tooling width
• Gooseneck depth
• Gooseneck clearance profile
• Tooling length
• Segmented tooling lengths
• Special relief structures
• Machine-specific mounting dimensions
• Button or positioning pin configuration
• Customized upper punches
• Customized lower dies
• Complete customized punch and die sets

For example, if a customer's workpiece cannot be bent because an existing flange collides with a standard punch, we can evaluate the drawing and modify the gooseneck profile, tooling height, tip width, or other dimensions to provide the required clearance.

This is one of the main advantages of custom press brake tooling.
