Abstract
A spool (20) made of thick metal sheet for a fine metal wire comprises a core (22), and two flanges (24), coupled to the core (12). The core (22) comprises two concentric drums, an inner drum (26) with inner diameter d, and an outer drum (28) with outer diameter D. The spool changes the load distribution of side pressure on the flanges and further improves the structural rigidity of the spool to against deformation.
Description
- The present invention relates to a spool on which a fine metal wire is wound. More specifically, the present invention relates to a spool made of thick metal sheet for a fine metal wire, such as a wire for a wire saw (hereinafter referred to as “saw wire”) or a wire to reinforce a rubber hose (hereinafter referred to as “host wire”), to wind thereon.
- A
conventional spool 10, as shown inFIG. 1 , has a core 12, and twoflanges 14. The twoflanges 14 are welded to the both ends of core 12. The core 12 and the twoflanges 14 are made of thick metal sheets such as carbon steel for machine structural use. - A fine metal wire to be wound on the above-mentioned spool is, for example, a fine metal wire having a diameter of 0.12 to 0.16 mm or less and serving as a saw wire, or a fine metal wire having a diameter of about 0.20 to 0.80 mm and serving as a hose wire. Another application is a fine metal wire having a diameter of about 0.12 to 0.40 mm and serving as a wire for a twisted steel cord to reinforce rubber products.
- In the case where the above-mentioned fine metal wire is wound on the spool under a predetermined tension (for example, a tension of 4 to 15 Newton), the winding tension causes a high tightening tension to the core, thus resulting in applying to the flanges a big force pushing them apart. And this force for pushing apart (hereinafter referred to as “side pressure”) causes the flanges at both ends to be pushed away in a direction that they separate from each other.
- In a typical application, a saw wire is used to cut silicon for microchips. To eliminate material waste and to maintain a high productivity, the customers are asking a spool winding with a fine wire with diameter of 0.12 mm and length of 800 km. As the diameter of the metal wire becomes smaller, or as the winding tension becomes larger, or as the reciprocating number of turns of the wire becomes larger, the side pressure generated becomes larger.
- To provide sufficient strength and rigidity to withstand such side pressure, the
conventional spool 10 utilizes the thick metal sheet with a thickness of about 20 mm to 50 mm. Accordingly, the conventional spool is so heavy that the operability thereof becomes very poor, and that the spool suffers from the high cost of transportation. Also, the conventional spool suffers from the high cost of materials and treatments. - Besides, since the side pressure is excessively large, even this mechanically strong spool can not avoid plastic deformation of the flanges and the drum. After repeated use of several times, the deformation of the spool is proceeding, or the spool is broken to become unusable. That is, the conventional spool has a disadvantage that it fails to ensure durability appropriate to the high costs.
- Therefore, it is an aim of the present invention to provide a spool for an extra fine metal wire having sufficient mechanical strength and repetitive usability, while achieving reduction in weight and cost, and a method of manufacturing same.
- The present invention relates to a spool made of thick metal sheet for a fine metal wire. The spool comprises a core and two flanges coupled to the drum. The core further comprises two concentric drums: an inner drum with inner diameter d, and an outer drum with outer diameter D. The present invention changes the load distribution of side pressure and further improves the structural rigidity of spool to against deformation.

outer drum 28. - φ is the outer diameter of the
flange 24. - H is the height of the
outer drum 28. - F2 is the side pressure, on the
flange 14. - F4 is the side pressure, on the
flange 24 - In
FIG. 1 , there is shown in cross section view of a conventional spool. Thespool 10 has a core 12 and twoflanges 14 coupled to the drum 12. - In
FIG. 2 , there is shown in A-A cross-sectional view of a spool incorporating the present invention. Thespool 20 has acore 22 and twoflanges 24 coupled to thecore 22, while thecore 22 comprises two concentric drums, aninner drum 26 with inner diameter d, and anouter drum 28 with outer diameter D. - As shown in
FIG. 3 , theflanges 14 are under the side pressure F2 generated from the tension of fine metal wire. The load distribution on a slice of theflange 14 can be simplified as a beam supported at one end with evenly distributed side pressure F2. While as shown inFIG. 4 , theflanges 24 are under the side pressure F4 generated from the tension of fine metal wire. The load distribution on a slice of theflange 24 can be simplified as a beam supported both at one end and at the middle with evenly distributed side pressure F4. This double supported beam is structural stronger than the beam supported at one end. - Besides, we find out:
- 1, the more layers of fine metal wire winded on the core, the higher the pressure on the core, because more metal wires exert tension on the core;
- 2, the more layers of fine metal wire winded on the core, the higher the side pressure on the flanges, because more metal wires exert tension on the flanges;
- Therefore, increasing the outer diameter D of the outer drum helps to reduce the layers of fine metal wire winded on the drum, and further helps to reduce the pressure on the core and side pressure on the flanges. Additionally, when φ and D are increased, the rotational speed of the spool during the winding and un-winding process decreases, this will make the positioning of the wire near the flanges more controlled and thus less problematic. But there is always a limit for the expansion of the outer diameter of the outer drum and the outer diameter of the flange, because the spool should fit with the space on the saw machines. Hence, the outer diameter D is between 1.3 and 2.1 times of the inner diameter d, while the outer diameter φ of the flange is between 2.2 and 2.8 times of the inner diameter d.
- A further improvement is to extend the height H of the spool to further reduce the layers of fine metal wire on the drum. Since the spool should fit with the space on the saw machines, there is a limit for the extension of the height H of the spool. Therefore, the height H of the spool, i.e. the height H of the outer drum, is between 2.0 and 3.0 times of the inner diameter d.
- The following comparison between a conventional spool, spool 0 and spools, spool 1 and spool 2, incorporating present invention can further illustrate the improvements and benefits. A conventional spool, as shown in
FIG. 1 , has the following specifications: d=150 mm; φ=315 mm; H=315 mm; - While spools incorporating present invention, as shown in
FIG. 2 , has the following specifications: -
d D φ H Spool 1 150 mm 230 mm 355 mm 326 mm Spool 2 150 mm 300 mm 400 mm 420 mm - If the spools, a conventional spool, spool 0, and two spools, spool 1 & spool 2, incorporating present invention, are to wind the same volume of fine metal wire, the pressure on the core, and the side pressure on the flanges of spools incorporating present invention decrease dramatically, while the structural rigidity increases drastically, compared with those of a conventional spool.
- With the improvements on the load distribution on the core and flanges, and the improvements on the structural rigidity of the spool, present invention can use thinner metal sheet with thickness between 2.5 mm and 7.0 mm, and preferably between 3.0 mm and 5.0 mm to make spools compared with conventional ones.
- The following table illustrates the improvements and benefits of the spools incorporating present invention.
-
Strength: Repetitive Usability Distance between Distance between Distance between Flanges after one Flanges with no wire flanges with no wire time full winding after one time use after 5 times use Spool 0 323.6 mm 318.3 mm 324.1 mm Spool 1 328.0 mm 326.5 mm 328.0 mm Spool 2 422.0 mm 420.5 mm 422.0 mm - The above comparison test further discloses that the ratio φ/D is also critical for this double drum spool. The smaller the ratio φ/D, the smaller the deformation of the spool after use, and therefore the more times reuse of the spool. But there should be some limits for ratio φ/D. On one hand, the lower limit for ratio φ/D should be greater than 1.0 because the outer diameter of the flange φ should be greater than the outer diameter D of the outer drum to make the spool workable. On the other hand, the upper limit for ratio φ/D should be no more than 2.0 because the higher the flange exceeds the outer drum the bigger the deformation of the spool after use. Therefore, the ratio φ/D is between 1.0 and 2.0, and more preferably, between 1.3 and 1.6.
- As shown In
FIG. 5 , theflange 24 has onecenter hole 30 and evenly distributedslots 32 around the center hole. As shown inFIG. 6 , there is a weld between the outer periphery of theinner drum 26 and the inner periphery of thecenter hole 30 on theflanges 24. As shown inFIG. 7 , there is a weld between the inner periphery of theouter drum 28 and the evenly distributedslots 32 on theflanges 24. The above arrangement has following advantages: - 1, improves the connection between the inner drum and the flanges;
- 2, improves the connection between the outer drum and the flanges;
- 3, guarantees the concentric between the inner drum and the outer drum;
- 4, limits the deformation of flanges because of the limited weld between the outer drum and the flanges;
- 5, easy to manufacture because of the simplified structure;
- As shown in
FIG. 8 , there is a weld between the outer periphery of theouter drum 28 and the surface of theflanges 24. This weld further improves the connection between the outer drum and the flanges, and improves the structural rigidity of the spool. - The method of manufacturing a spool incorporating present invention includes:
- 1, the
flange 24 is manufactured by press working of the thick metal sheet, and the outer periphery of theflange 24 is generally reinforced by a folding procedure. Thecenter hole 30 and the evenly distributedslots 32 are manufactured by the press working. - 2, the
inner drum 26 and theouter drum 28 are formed by bending a metal sheet into a cylindrical shape. - 3, the outer periphery of the
inner drum 26 is welded to the inner periphery of thecenter hole 30 on theflanges 24; - 4, the inner periphery of the
outer drum 28 is welded to the evenly distributedslots 32 on theflange 24; - 5, the outer periphery of the
outer drum 28 is welded to the surface of theflanges 24. - 6, both the ends of the
inner drum 26 can have a chamfer angle to facilitate the mounting the spool on the machines; - 7, the weld between the outer periphery of the
outer drum 28 and the surface of theflanges 24 can be cut and rounded to facilitate smooth winding and re-winding process. - Another improvement to present invention is to weld some support plates 34 between the outer periphery of the
inner drum 26 and the inner periphery of theouter drum 28 as shown inFIG. 9 . The support plates 34 improve the strength ofouter drum 28 against deformation, and make sure theinner drum 26 andouter drum 28 are concentric. - A further improvement to present invention is to make the chamfer angle around the
center hole 30 on theflanges 24 as shown inFIG. 10 , and to weld the ends of theouter drum 28 to the surface of theflanges 24. Therefore, it is not needed to weld between the ends of theinner drum 26 and the surface of theflanges 24 because the ends of theinner drum 28 are under a pressure against the surface of theflanges 24 when the spool is loaded with fine wire.
