Ultimate Guide For Press Brake Tooling [2024 Updated] - SC ...

Press brake upper molds (punches) are critical top-tooling used to shape sheet metal, typically made from hardened 42CrMo or Cr12MoV steel for high strength. Key types include straight knife, sash, and gooseneck (swan-neck) punches used for, respectively, standard, thick, or complex offset bends. They require inspection for pitting or wear on the R-radius edge to ensure precision, with standard lengths often ranging from 500mm to 835mm.

This video demonstrates how to make your own press brake dies:

Common Types:
- Straight/Knife Punch: Ideal for general-purpose bending and V-angles.
- Gooseneck/Swan-neck Punch: Designed for special bending tasks, such as forming narrow U-channels, as the shape helps avoid interference with already bent sections.
- Acute Angle Punch: Used for air bending and accommodating material spring back (e.g., 75-degree angles).
Material and Durability: Most industrial dies are made from 42CrMo, a high-strength alloy, though Cr12MoV is used for higher precision and longer life.
Wear Inspection: The bottom R-radius edge should be inspected for pitting, unevenness, or damage, which indicates a need for replacement.
Dimensions & Standards: Common segmented lengths include
,
, and
. Common, standard die heights for machines under 200 tons are often
.
Selection Criteria: The punch radius should typically match the material thickness for optimal results, and the upper tool must fit the machine’s specific clamping system (e.g., American style or European style).

Common Upper Mold Damages:

Cracking/Breaking: Due to excessive load or material fatigue.
Swelling: Caused by high impact pressures over time.
Bending/Deformation: Due to excessive force on small, delicate punches.

For precision applications, high-quality, hardened, and ground, or segmented (segmented to allow for smaller setup lengths) tooling is recommended, such as that from specialized suppliers like Amada or Trumpf.
