Overview
ISO 16367:2025 - Tools for pressing - Guide plates - U- and V-blocks defines the standardized dimensions, tolerances and designation for guide plates used in press tooling. This third edition updates geometric details (e.g., U‑shaped groove and profile symbols) and replaces the 2008 edition to ensure consistent interchangeability of U-blocks and V-blocks in press tools.
Key topics
- Scope: Main dimensions and tolerances of guide plates (U- and V-blocks) for press tools, plus rules for designation.
- Types covered:
- Type U (female) block - dimensions and features shown in Figure 1 and Table 1.
- Type V (male) block - dimensions and features shown in Figure 2 and Table 2.
- Combination assemblies (U + V) illustrated in Figure 3.
- Dimensional control: General tolerances referenced to ISO 2768‑1 (m); surface roughness values expressed in micrometres. Specific hole fits, pin and fastener details are referenced to ISO 4762 (hexagon socket head cap screws) and ISO 8733 (parallel pins).
- Edges: Undefined-shape edges to conform to ISO 13715.
- Material: Choice of material is left to the manufacturer’s discretion, allowing selection based on application (wear resistance, hardness, corrosion).
- Designation format: Standardized naming for procurement and documentation, e.g.
U- and V-block guiding plate ISO 16367 - 65 × 200 (width × length in mm).
Applications
ISO 16367:2025 is intended for organizations that design, manufacture, install or inspect press tooling and fixtures:
- Tool and die makers standardizing guide plate components for stamping, forming and pressing operations.
- Press manufacturers and tooling engineers specifying interchangeable guide plates to simplify maintenance and reduce downtime.
- Procurement and quality teams using the designation rules for part identification, ordering and inspection.
- CNC shops and suppliers producing standardized U- and V-blocks for tooling kits and replacement parts.
Practical value
- Ensures compatibility and interchangeability of guide plates across suppliers and tools.
- Reduces design ambiguity by referencing standardized dimensions and tolerances.
- Simplifies procurement and inventory by using a common designation format.
- Aids quality control with referenced tolerances, fastener and pin specifications.
