Overview
ISO 9182-5:2023 defines requirements for Type D end-locking guide pillars with flange used in press tools. The standard specifies the required dimensions and tolerances, gives guidance on material selection and hardness, and defines a clear designation format for components that meet the document's requirements. Dimensions are presented in Figure 1 and Table 1 of the standard; several standardized diameters and length combinations are defined to ensure compatibility across toolmakers.
Key Topics
- Dimensions and tolerances: End-locking guide pillar dimensions conform to the illustrations and tabulated values (Figure 1, Table 1). Tolerance classes and limit deviations reference ISO 286-2.
- Options: The standard provides Option A (without thread) and Option B (with thread) for pillar ends; thread details are given as options in the illustrations and tables.
- Material and hardness: Guidance on suitable materials is provided and a Rockwell C hardness requirement is stated in the document: "the hardness shall be +2 (56 ) HRC." (Rockwell C test method referenced to ISO 6508-1.)
- Designation: A concise designation format is specified (example from the standard):
- Guide pillar ISO 9182-5 – D – 20 × 20 × 80 – B (option with thread)
- Assembly aids and safety: Notes in the document recommend specific diameters (19, 24, 30, 38, 48, 60 mm) to prevent incorrect assembly of upper and lower die plates.
Applications
These guide pillars are intended for use in press tools and die sets where precise guidance, repeatable alignment and secure end-locking are required. Typical benefits and practical uses include:
- Ensuring interchangeability of pillars among dies from different manufacturers.
- Simplifying die assembly and preventing misalignment of upper and lower plates.
- Providing a standardized basis for specifying replacement or spare parts.
- Supporting designs that require either threaded or non-threaded end conditions.
