Typical Applications

This 85° R1 large gooseneck punch is designed for sheet metal applications where a conventional press brake punch cannot provide enough clearance around the workpiece.

Typical applications include:

• Large sheet metal components
• Deep profile bending
• Large box bending
• Channel and U-profile bending
• Offset bending
• Return flange bending
• Multi-step bending
• Complex sheet metal forming
• Large machinery components
• Industrial equipment panels
• Electrical cabinets and enclosures
• Structural sheet metal parts
• Components with large existing flanges
• Applications requiring relatively higher bending force

Large Gooseneck Clearance for Complex Workpieces

The defining advantage of this tooling is the combination of its 175 mm height and 78 mm width.

The large overall dimensions allow the punch to incorporate a substantial gooseneck clearance area. This provides considerably more room for the workpiece during bending and is especially useful when the component has already been partially formed.

During multi-step bending, existing flanges or formed sections can interfere with the body of a conventional straight punch. This can limit the bending sequence or even make certain operations impossible.

The large gooseneck structure creates additional space around these formed sections, helping:

• Reduce tooling-to-workpiece collision
• Increase flange clearance
• Improve punch accessibility
• Accommodate larger formed sections
• Simplify complex bending sequences
• Improve flexibility when bending deep profiles

This makes the tooling particularly suitable for large, deep, and geometrically complex sheet metal components.

Large Clearance with Increased Tooling Strength

A key advantage of this model is that the large gooseneck structure is not designed only for maximum clearance.

The tooling maintains a relatively substantial structural configuration, allowing it to achieve an 80 ton/m load capacity.

This provides a useful balance between:

Large Clearance + Tooling Strength + Higher Load Capacity

Compared with gooseneck punches designed primarily for small or narrow workpieces, this model can be used for applications requiring somewhat higher bending force and relatively thicker sheet metal, provided the actual bending conditions are within the tooling and machine limits.

The 10 mm tip width also contributes to a stable working contact area while maintaining good access to the workpiece.

Suitable for Relatively Thicker Sheet Metal

The 80 ton/m capacity makes this tooling particularly useful when a customer needs a large-clearance gooseneck punch but also cannot sacrifice too much load-bearing capability.

For example, a customer may need to bend:

• A large workpiece
• A deep profile
• A component with large flanges
• A complex multi-step part

while also working with material that is somewhat thicker than the sheet typically processed using lower-capacity narrow gooseneck tooling.

In these cases, the large structure and 80 ton/m capacity provide a better balance between clearance and strength.

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

Product Details & Manufacturing Quality

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

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

The R1 tip radius provides a practical forming geometry for general industrial sheet metal bending, while the 10 mm tip width provides stable contact with the workpiece.

The most important structural characteristics are the 175 mm overall height and 78 mm total width.

These dimensions provide the space required for a large gooseneck structure while maintaining sufficient material around the working section to support an 80 ton/m rated load capacity.

This combination makes the punch suitable for applications where both large workpiece clearance and relatively high bending force are required.

Standard & Custom Gooseneck Press Brake Tooling

We manufacture standard gooseneck punches and customized press brake tooling for different machines, materials, and workpiece geometries.

Large gooseneck tooling is often application-specific. The required clearance depends on the size and shape of the finished workpiece, the bending sequence, flange height, and the position of previously formed sections.

Customers can send us:

• 2D workpiece drawings
• 3D models
• Bending drawings
• Existing tooling drawings
• Machine specifications
• Workpiece samples

Our engineering team can provide a free press brake tooling design service and recommend the appropriate gooseneck geometry.

Customization options include:

• Overall tooling height
• Total tooling width
• Gooseneck depth
• Gooseneck opening
• Clearance geometry
• Tip width
• Tip radius
• Punch angle
• Tooling length
• Special relief structures
• Reinforced tooling structures
• Machine-specific mounting dimensions
• Customized upper and lower tooling sets

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

This enables us to design a custom gooseneck punch around the customer's actual workpiece, rather than simply selecting a standard tooling profile.
