GB/T 6110-2021Drawing dies—Carbide alloy drawing dies—Structural types and dimensions (English PDF)

Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.

This document serves as a replacement of GB/T 6110-2008 Carbide Dies for Drawing - Types and Dimensions. In comparison with GB/T 6110-2008, apart from structural adjustments and editorial modifications, the main technical changes are as follows:

a) The title of the Standard is modified into Drawing Dies - Carbide Alloy Drawing Dies - Structural Types and Dimensions, and the corresponding English translation is modified;

b) The Chapter "Terms and Definitions" is added, and the terms and definitions of GB/T 8845 are quoted (see Chapter 3);

c) A description of the cross-sectional shape of each structural type is added (see 4.1; 3.1 of Version 2008);

d) The original three drawing dies of Type-A, Type-B and Type-F with circular cross-sections are merged into Type-A, which is further sub-divided into Type-A1 and Type-A2 in accordance with the applicable materials (see 4.2; 3.2, 3.3 and 3.7 of Version 2008);

e) The original Type-C, Type-D and Type-E drawing dies are respectively modified into Type-B, Type-C and Type-D; the structural types of Type-E and Type-F are re-defined;

f) The structure diagram of the drawing dies is improved and the requirements for undeclared chamfers are added (see Figure 1 ~ Figure 7; Figure 1 ~ Figure 6 of Version 2008);

g) The dimensions and specifications of Type-A drawing dies are modified (see Table 1 and Table 2; Table 1 and Table 6 of Version 2008);

h) The dimensions and specifications of Type-C drawing dies are added (see Table 3; Table 3 of Version 2008);

i) Two core structures of drawing dies with fan-shaped ad spiral cross-sections are added (see 4.6 and 4.7);

j) Recommended materials and performance requirements are added (see Table 8; Chapter 4 of Version 2008);

k) The requirements for the magnitude of interference are refined, and requirements are put forward for the temperature and magnitude of interference of cold setting and hot setting die sleeves (see 6.1; Chapter 5 of Version 2008);
