ISO 1651:1974/Amd 1:1982

Overview

ISO 1651:1974/Amd 1:1982 is an important amendment to the original ISO 1651:1974 standard, focusing specifically on tube drawing mandrels. Published by the International Organization for Standardization (ISO), this amendment updates the dimensions and classification of hardmetal (carbide) core tube drawing plugs used in metal forming processes. It revises terminology and clause titles to improve clarity and applicability for manufacturers and users of tube drawing tools.

This standard ensures consistent specifications for both solid-head and sleeved-head tube drawing plugs, which are essential components in tube drawing operations aimed at shaping metal tubes with high precision.

Key Topics

• Hardmetal (carbide) core tube drawing plugs: The amendment modifies the general title to specify these plugs and emphasize their material properties for durability and performance.
• Revised clause titles:
  • Clause 1 redefines the scope and key dimensions relevant to these plugs.
  • Clause 2 is titled “Solid-head tube drawing plugs,” covering specifications for plugs with a solid construction.
  • Clause 3 is titled “Sleeved-head tube drawing plugs,” describing specifications for plugs with a sleeved assembly.
• Dimensional specifications: The document specifies the precise measurements related to the diameter and construction types of tube drawing plugs, which are critical for ensuring tooling compatibility and product quality.
• Technical Committee ISO/TC 29 involvement: The standard was developed by experts specializing in small tools, reflecting international consensus.

Applications

ISO 1651:1974/Amd 1:1982 is highly valuable for industries relying on tube drawing processes including:

• Metal fabrication and manufacturing: Ensures reliability and interchangeability of tube drawing plugs used in shaping tubes for automotive, aerospace, and construction sectors.
• Toolmakers and precision engineering: Provides clear dimensional standards for producing carbide core mandrels, contributing to improved tooling accuracy and longevity.
• Quality assurance: Assists in maintaining consistent production quality through standardized plug dimensions, reducing variability in tube diameters and wall thicknesses.
• Research and development: Supports innovation by defining clear baseline specifications for evaluating new materials and tooling designs in tube drawing.

Related Standards

To complement ISO 1651:1974/Amd 1:1982, users may consider related standards including:

• ISO 4948 - Dimensions for metal forming tools: Provides additional specifications for tooling dimensions and tolerances.
