ISO 21223:2019

Overview

ISO 21223:2019 is an international standard published by the International Organization for Standardization (ISO) that establishes the vocabulary related to tools for pressing. It provides comprehensive terms and definitions for the main types of pressing tools, their features, and dimensional characteristics. This standard is essential for manufacturers and users involved in the design, production, and trade of pressing tools, ensuring clear communication and a common understanding of technical terminology.

The document covers classification, parts, components, and design elements of pressing tools. Included are explanations for various types of dies such as blanking, forming, drawing, bending, compound, and progressive dies, among others. Illustrative figures and an informative annex help users visualize the described terms and components.

Key Topics

• Types of Tools for Pressing

  • Stamping dies designed for shaping, cutting, or joining materials.
  • Specific dies like blanking dies, bending dies, forming dies, and drawing dies.
  • Specialty dies including fine blanking, hydroforming, microforming, and hot stamping dies.
  • Compound, progressive, transfer, and flexible dies designed for multifunctional or automated pressing operations.

• Parts and Components

  • Die sets including standardized and quick change varieties with options for rear, diagonal, center, and four-pillar guide posts.
  • Critical components such as upper and lower dies, die plates, punches, matrices, die buttons, inserts, guide pillars, and bushes.
  • Functional elements like feed limiters, locating pins and plates, stop pins, pilot punches, strip lifter pins, guide rails, backing plates, retainer plates, and automatic feeders.
  • Guide elements that ensure precise alignment during operation.

• Dimensional Characteristics and Design Elements

  • Focus on geometric features of tools such as cutting edges, punch shapes, and deformation zones.
  • Classification according to the specific deformation or cutting function.
  • Design for accuracy, precision, and consistency in stamping and forming operations.

Applications

ISO 21223:2019 serves as an essential reference for:

• Manufacturers of pressing tools and stamping dies to ensure components meet international terminology and dimensional standards.
• Users and engineers involved in the design and operation of pressing and forming machinery.
• Quality control and procurement professionals who require clear definitions for specifications and communication with suppliers.
• Trade and communication related to tooling and press operations, offering a standardized vocabulary for contracts, documentation, and training materials.
• Research and development for innovation in tool design, enabling precise classification and description of evolving pressing technologies.

The standard supports efficient collaboration within the metal forming, automotive, aerospace, and electronics industries where sheet and section pressing tools are extensively used.
