The work of preparing International Standa

13、rds is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also tak

14、e part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is

15、 to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibilit

16、y that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8977 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 8, Tools for pressing and moulding. Th

17、is second edition cancels and replaces the first edition (ISO 8977:1987), clause 3 of which has been technically revised. Annex A of this International Standard is for information only.

18、ard lays down the basic dimensions and tolerances in millimetres for headless and headed matrixes, in the outside diameter range of 5 mm to 50 mm. It gives examples of material and hardness, and specifies a designation for matrixes that meet the requirements of this International Standard. The dimen

19、sions and tolerances of the matrixes specified in this International Standard are adapted to conform to those for punches specified in ISO 8020. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this Internation

20、al Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indica

21、ted below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

31、point diameter, d (if required); g) its overall length, L; h) the depth of the working part, l; i) its material (alloyed cold work steel with 5 % to 12 % Cr or high speed steel). EXAMPLE A headless matrix, type A, of external diameter D = 10 mm with an h5 tolerance, point diameter d = 4 mm, total le

32、ngth L = 20 mm and having a depth of working part l = 4 mm in high speed steel is designated as follows: Matrix ISO 8977 - A 10 h5 4 20 4 - high speed steel BSISO8977:20036 Annex A (informative) Example of matrixes A.1 General Matrixes in accordance with this International Standard are also used wit

33、h cutting shapes other than round ones. Examples for matrixes with square, rectangular or oblong shapes are shown in clause A.2. The dimensions of matrixes in clause A.2 are adapted to the types of punches in accordance with ISO 8020. Matrixes (punches) with other than round shapes are designed so t

34、hat on assembly, they can only be mounted in one direction. This can be achieved by fitting the matrixes with a locking device. For matrixes, this device is always fitted on the longest side of the shape (profile) and thus complies with the requirements for punches in accordance with ISO 8020. A.2 E
