Upper punch component for V-die sets in sheet metal bending operations
The upper punch is a precision tooling component in V-die sets used for sheet metal bending operations. It is mounted on the press ram and descends to force sheet metal into the V-shaped lower die, creating controlled bends with specific angles and radii. This component directly contacts the workpiece and determines the bend geometry through its tip profile and dimensional accuracy.

Standard punches follow common industry dimensions and radii for general applications, while custom punches are engineered for specific bend geometries, specialized materials, or unique production requirements with non-standard angles or profiles.
Inspect upper punches every 8,000-10,000 cycles in normal production environments. High-volume operations or abrasive materials may require inspection every 5,000 cycles. Key wear indicators include radius deformation, surface scoring, and dimensional changes exceeding 0.05 mm.
Yes, qualified punches can be reground to restore the original radius profile and surface finish, typically allowing 2-3 regrinds before replacement. This requires precision grinding equipment and heat treatment expertise to maintain hardness specifications.
