11、ii BSI 12-1999 Foreword This British Standard has been prepared under the direction of the Non-Ferrous Metals Standards Committee from a draft by the High Conductivity Copper Group of the British Non-Ferrous Metals Federation. The High Conductivity Copper Group recognized the need to establish a bas

12、is for the standardization of spools used for winding bare drawn copper wire for further internal processing by the manufacturer or for supply to customers for off-winding by established methods including ballooning over the flange. The progressive development of faster wiredrawing and processing sp

13、eeds demands improved winding and tensioning control standards and in many cases larger package weights. In discussion with wiredrawing machinery makers, it was evident that the practical development of automatic controls to improve the quality of winding is seriously impeded by the wide variety of

14、spools in current use. As a long term project, therefore, the High Conductivity Copper Group decided to establish a limited range of wiredrawing spool sizes in the interests of standardization. The first step was to determine a reasonable progression of nominal copper capacities and acceptable param

15、eters for flange to barrel ratios suitable for ballooning and other non-rotational off-winding methods. In collaboration with manufacturers of spools and wiredrawing machinery, consideration was also given to other important features such as larger barrel diameters to reduce stress at elevated wired

16、rawing speeds, optimum bore diameters for secure spool mounting, standard driving mechanism and material availability. In addition, this standard is generally consistent with the requirements of the German Standard DIN 46397 which deals with annealing and machine spools. The selected dimensions gene

17、rally conform to the R10/R20 basic series of preferred numbers but with certain exceptions which are related to practical considerations, including the availability of standard sizes of steel tube suitable for machining to the smaller barrel diameters. Because of the very large capital investment in

18、 existing spools and, in some cases, the problems associated with machinery limitations, no rapid change is envisaged. In the longer term, however, the increasing use of standard spools will facilitate the development of improved automatic winding controls and simplify the design of spooling and off

19、-winding equipment. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This

22、aling where required. It includes recommendations for tolerances, bore profiling and driving mechanism. 2 References The titles of the publications referred to in this standard are listed on the inside back cover. 3 Materials and construction Spools shall be so constructed and made from such materia

23、ls that they are of adequate strength for their intended use. The flange rims may be plain or with heavy duty curled edges. Normally, spools are constructed from a grade of steel suitable to withstand the mechanical stresses imposed in winding at high speeds of rotation and suitable for repetitive b

24、atch annealing. For applications not involving batch annealing, spools may be constructed from other materials such as moulded plastic or aluminium alloy at the discretion of the purchaser. Constructional details shall be the responsibility of the spool manufacturer unless otherwise agreed between t

25、he purchaser and the supplier. 4 Dimensions The spool size shall be denoted by the nominal copper capacity and flange diameter required. The dimensions of the spools shall be as detailed in Table 1 and may be identified by reference to Figure 1 which does not necessarily illustrate the spool constru

30、l spool drawings. In cases where such requirements are not specified, the following tolerances and limits are offered as a general guide. 5.1 The tolerances on spool dimensions should conform to those shown in Figure 1 and detailed in Table 2. 5.2 General notes on tolerances and limits. Spools of 10

31、 kg and 25 kg capacity are normally machined all over; suitable tolerances are shown in Table 2. Run-outs, cylindricity and concentricity on such spools are negligible and are therefore excluded from the table. For spools of 50 kg capacity and larger, the tolerances given are based on a curled edge

32、flange construction with barrel and bore machined concentrically. 5.3 Bore taper. Except where parallel bores are specified, the bore extremities shall be machined to an included angle of 40 0.5 and to a nominal depth of 12 mm. To avoid damage to the outer edge of the taper, a radius or chamfer shou

33、ld be incorporated. 5.4 Traverse. The traverse width shall be measured on the barrel line. 5.5 Overall width. The overall width shall be measured through the bore. 5.6 Run-out of flange face (FIM) Limit (1). This measurement shall be taken 20 mm below the periphery of the flange. Every effort shall

34、be made to ensure that the angle between flange and barrel is not less than 90. 5.7 Surface texture. Recommended levels of surface texture are as follows. 5.8 Dynamic balancing. It is recommended that spools for use at high rotational speeds shall be dynamically balanced. The permissible residual un

35、balance shall be agreed between the purchaser and the supplier and shall comply with the requirements of ISO 1940. The recommended grade is G.40. NOTEDependent on the rotational speed and balance quality grade selected, a dynamically balanced spool may require a finer cylindricity limit (2) than tha

The contents shall be protected by a suitable wrapping which shall have no deleterious effect on the copper wire. The type of protective wrapping will be dependent on the method of handling and stora
