Описание (английский):

ISO 9181:2007 specifies the dimensions and tolerances, in millimetres, for round punches with a 60° conical head and reduced shank, having shank diameters of 2 mm or 3 mm. ISO 9181:2006 gives examples of materials and hardness, and specifies the designation of punches which meet the requirements of this document. The main use of punches defined in ISO 9181:2006 is for punching holes in steel sheet. They may also be used for punching holes in other materials.

Overview

ISO 9181:2007 is an international standard published by ISO that specifies the dimensions and tolerances for round punches featuring a 60° conical head and reduced shank. This standard precisely defines measurements for punches with shank diameters of 2 mm or 3 mm, primarily intended for punching holes in steel sheets. It also provides guidance on material selection, hardness values, and the proper designation format for punches compliant with the standard.

The standard was developed by ISO Technical Committee ISO/TC 29, Subcommittee SC 8, focusing on press and molding tools. It replaces the earlier ISO 9181:1990 edition with minor revisions, including an update to surface finish specification according to ISO 1302:2002.

Key Topics

Dimensions and Tolerances: ISO 9181:2007 specifies dimensional requirements in millimeters for round punches, including diameter of the reduced shank (2 mm or 3 mm), diameter of the working part, and total length. Precise tolerances ensure interchangeability and consistent performance in industrial pressing applications.

Material Recommendations: Although the choice of materials is left to manufacturers, the standard suggests typical hardness values to ensure durability and effectiveness:

Tool steels with 12% chromium:
- Working part hardness: (62 ± 2) HRC
- Head hardness: (45 ± 5) HRC
High-speed steels:
- Working part hardness: (64 ± 2) HRC
- Head hardness: (50 ± 5) HRC

Designation System: A standardized naming format describes each punch, including the type, ISO reference, shank diameter, working diameter, and total length. Example: "Round punch with conical head ISO 9181 - 2 × 0.5 × 71" indicates a 2 mm shank diameter, 0.5 mm working diameter, and 71 mm overall length.

Surface Finish: The standard references ISO 1302:2002 for surface roughness indications to guarantee optimal tool performance and longevity.

Applications

Steel Sheet Punching: The main application of punches defined by ISO 9181:2007 is creating precise holes in steel sheets for manufacturing processes such as automotive, appliance, and metal fabrication industries.

Multi-Material Use: While intended for steel, these punches are also suitable for perforating other materials, broadening their utility in various manufacturing contexts.

Press Tooling: These punches function as critical components in pressing and punching tools used in mechanical presses, ensuring consistency, quality, and efficiency in hole-making operations.
