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

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
