JB/T 10001-1999 Hexagonal Dies

JB/T 10001-1999 This standard is a revision of ZB J41 018-89 "Hexagonal Dies". During the revision, the hardness value of the hexagonal dies was adjusted, and the evaluation conclusion of the test results was added. Editorial changes were made according to relevant regulations, and other technical contents remained unchanged. The original standard non-equivalently adopted the international standard ISO 7226-1988 "Dimensions of Hexagonal Dies". This standard specifies the type and size, technical requirements, performance tests, and basic requirements for marking and packaging of hexagonal dies. This standard is applicable to hexagonal dies for processing ordinary threads (according to GB/T 191~193, GB/T 196~197), non-threaded sealed pipe threads (according to GB/T 7307-1987 "Non-threaded Sealed Pipe Threads"), threaded sealed pipe threads (according to GB/T 7306-1987 "Threaded Sealed Pipe Threads") and other threads. This standard was first published on the date of year. JB/T 10001-1999 Hexagonal Die JB/T10001-1999 Standard download decompression password: www.bzxz.net

4 Technical requirements
4.1 The surface of the hexagonal die shall be free from defects such as creases, front edges, rust and chipping burns that may affect its performance. 4.2 The surface tolerances of the hexagonal die shall be in accordance with the following provisions: End face and hexagonal box:
h) Thread surface:
R.12.5μm
h) Front and back faces of cutting edges: R6.3m
4.3 The position tolerances of the hexagonal die are given in Table 3. Table 3
Basic thread diameter
Surface movement of the front edge to the thread axis
Oblique movement of the front cutting edge to the effective axis 0.15
4.4 Hexagonal dies are made of 9SiC or alloy with equivalent properties or above, and the hardness of the threaded part is not less than 60HRC. According to user requirements, they can also be made of high-strength steel, and the hardness of the effective part is not less than 62HKC. 5 Performance test objects
