Problems solved by technology

Although it is strong, it can only be used once, because the flange will plastically deform after one cycle of use
Furthermore, such spools are not designed to have wire 0.120mm in diameter or less wound thereon

Embodiment Construction

[0033] figure 1A first embodiment of a spool 10 according to the invention is shown. The spool 10 includes a core 12 and two flanges 14 respectively welded on both ends of the core 12 . The two flanges 14 are provided with six recessed areas 16 extending radially from the core 12 and distributed at equiangular intervals. The shape of the recessed area 16 is substantially rectangular. Two protruding drive posts 18 are provided for pulling the spool 10 during use. The two flanges can have edges 20, but this is not necessary for the invention.

[0034] figure 2 is a side view of a first embodiment of a spool according to the invention, wherein the core 12 has an outer diameter D1 and the two flanges 14 have an outer diameter D2. In the first embodiment, D1 is 156 mm and D2 is 310 mm. The free radius of the flange is (D2-D1) / 2, which is 77mm. The six recessed areas 16 have a substantially rectangular shape with a radial dimension of 40 mm, ie approximately 50% of the free ...

Abstract

The invention relates to a spool for winding fine metal wire on, comprising a core and two flanges coupled to either end of said core, wherein the outer side of each of said flanges comprises multiple debossed areas that extend radial from said core and are evenly distributed around said core. The debossed areas reduce the spreading of the flanges when winding fine metal wire on.

Description

technical field [0001] This invention relates to spools on which wire is wound. More specifically, the present invention relates to spools made of sheet metal for having saw wire wound thereon. Background technique [0002] A traditional spool has a core and two flanges. These two flanges are for example welded at both ends of the core. The core and the two flanges are made of carbon steel, 1-6mm thick sheet metal. [0003] One example of wire wound on the spool is saw wire. The diameter of the sawing wire is between 0.08-0.16mm, the most typical diameter is 0.12mm, however 0.25mm sawing wire is also known to exist. The development trend of sawing wire is thinner and longer. Saw wires are used on loose abrasive sawing machines where the wire draws a slurry containing a liquid carrier and abrasive particles into a growing cut in the material being sawed. Such sawing machines are widely used for cutting silicon ingots used in the semiconductor industry or in the manufact...
