Typical Applications

This 85° R0.5 high gooseneck punch is designed for sheet metal bending applications where both increased tooling height and additional workpiece clearance are required.

Typical applications include:

• Deep sheet metal bending
• Higher profile bending
• Complex profile bending
• Offset bending
• Box and channel bending
• Return flange bending
• Multi-step bending
• Previously formed workpieces
• Components with multiple flanges
• Electrical cabinets and enclosures
• Machinery components
• Structural sheet metal parts
• Precision industrial components
• Complex CNC press brake forming

Gooseneck Structure for Workpiece Clearance

The most important characteristic of this tooling is the gooseneck structure.

During a multi-step bending operation, the workpiece may already contain one or more formed flanges. When the next bending operation is performed, these existing sections may interfere with a conventional straight punch.

The gooseneck structure creates an additional clearance area around the workpiece, allowing previously formed sections to move into the available space.

This helps:

• Reduce the possibility of tooling collision
• Improve clearance around existing flanges
• Reduce interference during subsequent bending operations
• Improve punch accessibility
• Make complex bending sequences easier
• Increase flexibility when forming irregular sheet metal profiles

The clearance is particularly useful when the workpiece geometry makes a conventional straight punch difficult or impossible to use.

High 150 mm Tooling for Deeper Applications

In addition to the gooseneck structure, this model features a 150 mm overall height.

Compared with standard 97 mm or 120 mm upper punches, the higher tooling profile provides additional working reach and can be advantageous when bending deeper or higher components.

The combination of:

150 mm height + 50 mm gooseneck width + 9 mm tip + additional clearance

makes this tooling suitable for applications where both tooling reach and workpiece clearance are important.

The tooling can be manufactured for press brake applications involving major brands and tooling systems, including Amada, TRUMPF, LVD, Bystronic, and WILA, subject to the specific machine interface and tooling requirements.

Product Details & Manufacturing Quality

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

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

The R0.5 tip radius provides controlled contact with the workpiece and is suitable for applications requiring a relatively small forming radius.

The main structural feature is the gooseneck profile, which creates additional clearance around the workpiece.

Unlike a conventional straight punch, the gooseneck configuration provides a recessed area that allows certain parts of the workpiece to move into the clearance area during bending.

This is especially useful for multi-step bending, where the workpiece has already been partially formed.

The 150 mm height further expands the range of applications by providing additional reach for deeper or higher components.

The tooling has a rated load capacity of 50 ton/m. Actual allowable bending force should always be determined according to material type, sheet thickness, bending length, die opening, bending method, and press brake specifications.

Standard & Custom Gooseneck Press Brake Tooling

We manufacture standard gooseneck punches and custom-designed press brake tooling according to different machine and workpiece requirements.

Gooseneck tooling is particularly suitable for customers who experience tool-to-workpiece interference when using conventional straight punches.

If your workpiece has a special shape, existing flange, deep profile, or restricted bending area, you can send us your:

• 2D workpiece drawing
• 3D model
• Bending drawing
• Existing tooling drawing
• Machine specifications
• Workpiece sample

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

Customization options include:

• Overall tooling height
• Total tooling width
• Gooseneck depth
• Gooseneck opening
• Clearance geometry
• Tip width
• Tip radius
• Punch angle
• Tooling length
• Front/rear clearance

• Interference-avoidance structures
• Machine-specific mounting dimensions
• Customized upper and lower tooling sets

For complex applications, we can also evaluate tool-to-workpiece interference, bending sequence, flange clearance, punch accessibility, tooling height, and required bending force before manufacturing.

This allows us to provide a custom gooseneck press brake tooling solution based on the actual workpiece geometry.
