Technical Specifications

Typical Applications

This 85° R1 high press brake upper punch is specially designed for applications where conventional press brake punches may have insufficient clearance around the workpiece.

The narrow 9 mm load-bearing section provides additional space around the working area, making the tooling particularly suitable for:

• Closed-profile bending
• Semi-closed profile bending
• Narrow opening or restricted-access bending
• Deep channel and box-type components
• Complex sheet metal profiles
• Bending near existing flanges
• Parts with narrow return flanges
• Electrical enclosures and cabinets
• Machinery components
• Automotive sheet metal components
• Precision brackets and formed structures
• Multi-step and sequential bending operations

The 120 mm overall height provides additional reach for applications where a taller punch is advantageous. Combined with the narrow 9 mm working section, the design helps create more available space between the tooling and workpiece.

For closed or nearly closed components, this additional clearance can make it easier to position the workpiece and complete the required bending operation while reducing potential interference between the tooling and previously formed sections.

This tooling can be configured for applications involving major press brake brands and tooling systems, including Amada, TRUMPF, LVD, Bystronic, and WILA, subject to the machine's specific tooling interface.

Product Details & Manufacturing Quality

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

The working section is heat treated to approximately HRC 54 ± 2, helping maintain the tooling's dimensional accuracy and working profile during long-term use.

The combination of an 85° punch angle, R1 tip radius, 120 mm overall height, and 9 mm load-bearing section creates a specialized tooling geometry for applications requiring increased workpiece accessibility.

Compared with conventional wider punches, the narrow working section can provide additional clearance around the workpiece. This is particularly useful for closed profiles, deep channels, narrow openings, and complex formed components where standard tooling may encounter interference.

The 80 ton/m load capacity makes the punch suitable for a wide range of industrial sheet metal bending applications. Actual bending force and tooling selection should be determined according to material, thickness, bending length, die opening, bending method, and press brake specifications.

Standard & Custom Press Brake Tooling

We provide standard press brake punches and dies as well as fully customized bending tools for special applications.

For closed-profile or complex components, selecting the correct tooling geometry is particularly important. A standard punch may not provide sufficient clearance, or the tooling may interfere with previously formed sections of the workpiece.

Customers can send us their 2D/3D drawings, bending drawings, workpiece samples, or machine information. Our engineering team can provide a free press brake tooling design service and recommend an appropriate tooling configuration.

We can customize:

• Overall tooling height
• Total tooling width
• Load-bearing section width
• Punch angle
• Tip radius
• Tip width
• Tooling length
• Clearance and relief dimensions
• Special interference-avoidance structures
• Gooseneck punches
• Special-shaped punches
• Machine-specific tooling dimensions
• Customized upper and lower tooling sets

For complex bending applications, our engineers can also evaluate closed-profile clearance, flange interference, bending sequence, workpiece accessibility, and tooling geometry before manufacturing.

This allows us to provide a complete custom press brake tooling solution based on the customer's actual workpiece rather than simply supplying a standard punch.
