Typical Applications

This 85° R1 wide gooseneck punch is designed for applications where a conventional straight punch or narrow gooseneck punch does not provide sufficient clearance around the workpiece.

Typical applications include:

• Large sheet metal components
• Deep profile bending
• Complex sheet metal forming
• Offset bending
• Box bending
• Channel bending
• Return flange bending
• Multi-step bending
• Components with large flanges
• Previously formed workpieces
• Machinery components
• Electrical cabinets and enclosures
• Industrial equipment panels
• Structural sheet metal parts
• CNC press brake forming

Very Large Clearance from a Wide Gooseneck Structure

The defining characteristic of this tooling is its 75 mm total width.

Compared with narrower gooseneck punches, the wider body provides more structural space for creating a large clearance area around the workpiece.

This is particularly valuable when a workpiece has already undergone one or more bending operations.

As the bending sequence progresses, previously formed flanges may extend into the working area of the punch. If the available clearance is insufficient, the workpiece can interfere with the punch body.

The wide gooseneck structure provides additional space for these formed sections, helping:

• Reduce punch-to-workpiece collision
• Increase flange clearance
• Accommodate larger formed sections
• Improve punch accessibility
• Provide greater flexibility in bending sequences
• Reduce interference during complex forming operations

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

Wide Structure Designed for Large Clearance

The 75 mm width is the primary feature that differentiates this model from standard-width gooseneck punches.

Rather than simply providing a narrow relief area, the wider body allows the tooling to create a much larger clearance zone.

This can be particularly useful when the workpiece has:

• Deep flanges
• Large return bends
• High side walls
• Multiple formed sections
• Large overall dimensions
• Complex profiles
• Restricted bending areas

The 145 mm height further provides sufficient working reach for deeper and higher-profile components.

The combination of:

145 mm height + 75 mm width + 8.5 mm tip + 50 ton/m capacity

creates a balanced solution for customers who require substantial clearance without moving to an extremely large or high-capacity tooling configuration.

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 area 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 sheet metal applications, while the 8.5 mm tip width offers stable contact with the workpiece.

The tooling's primary structural advantage is its 75 mm wide gooseneck body, which provides the space required for a large clearance area.

The rated load capacity is 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 press brake tooling according to different machine and workpiece requirements.

For applications where a standard punch cannot provide sufficient clearance, our engineering team can design a customized gooseneck structure based on the actual geometry of the customer's component.

Customers can send us:

• 2D workpiece drawings
• 3D models
• Bending drawings
• Existing tooling drawings
• Press brake machine specifications
• Workpiece samples

We provide a free press brake tooling design service to help customers select or develop the most appropriate tooling.

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

For complex applications, we can evaluate workpiece clearance, flange geometry, bending sequence, punch accessibility, collision risk, and required bending force before manufacturing.

This allows us to provide a custom gooseneck punch designed specifically around the customer's workpiece.
