<P>PROBLEM TO BE SOLVED: To provide a reinforcing member for suppressing deformation of a reel flange due to winding tension when a metallic wire is wound around a reel. <P>SOLUTION: The reinforcing member 20 of the reel for the metallic wire has a cylindrical winding drum part 1 and a pair of flanges 2 integrally provided on right and left ends thereof, and is formed by a cylindrical main body part 5 capable of covering a roughly entire metallic wire winding face of the winding drum part 1, and a pair of flange parts 6 integrally formed at both ends of the main body part 5, having the substantially same outer diameter as the flanges 2 of the reel, and welded to the flanges 2. Stress accompanying welding distortion caused by welding remains as initial stress for pulling the flanges inward. The deformation of the flange of the reel is suppressed by opposing the initial stress to force, by which the flanges are spread in a direction where the flanges are separated from each other with side pressure. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a reel reinforcing member for winding a metal wire body and a metal wire body winding reel to which the reinforcing member is attached, and particularly when the metal wire body is wound on a reel. The present invention relates to a reel reinforcing member that functions to suppress a deformation in which both flanges of a reel are pushed apart in a direction away from each other by winding tension (side pressure), and a metal wire wound reel to which the reel reinforcing member is attached. Note that the reel reinforcing member also has a function of suppressing deformation in which the diameter of the central portion of the saddle drum portion is reduced by a tightening force (winding pressure) that acts on the reel saddle drum portion due to winding tension.

  In general, a reel 01 for winding a metal wire body is configured by a rod body part 02 and a pair of flanges 03 and 03 disposed at both ends of the rod body part 02 as shown in FIGS. Has been. The rod body part 02 and the pair of flanges 03, 03 are made of a thick steel material such as structural carbon steel (for example, S45C). Then, depending on the method of manufacture, separately manufacture the integrated reel (machined reel) that has been carved out the flange body 02 and the flanges 03, 03, and the flange body 02 and the flanges 03, 03 separately, It is classified into a welding reel (assembly reel) in which the flange body portion 02 and the flanges 03 and 03 are welded.

  On these reels, metal wire bodies, for example, ultrafine metal wires for wire saws having a wire diameter of 0.12 to 0.16 mm (or less), or strands of stranded steel cords (tire cords) for reinforcing rubber products When an extra fine metal wire (including steel cord in some cases) with a predetermined tension (for example, 0.4 kg to 1.5 kg) is wound as a wire diameter of 0.15 to 0.40 mm Due to the tension, a large tightening force is applied to the rod body, and this tightening force acts to cause a deformation that pushes both flanges away from each other. Such a force acting to expand the flange outward is referred to as “side pressure”.

This lateral pressure increases as the wire diameter of the metal filament is smaller, as the winding tension is larger, and as the number of winding reciprocations is larger. In the case of the above-mentioned ultrafine metal wire, for example, a wire saw, a reel is wound with a weight of 40 to 60 kg or more. In such a case, the side pressure may reach several tons or several tens of tons.

Due to this lateral pressure, the flange is deformed so as to spread both flanges away from each other, as shown by the dotted line in FIG. 10, and this phenomenon is caused by the width of the flange part as shown in FIG. This is particularly noticeable in the case of a reel having a flange diameter L larger than H (H <L, referred to as “slim type reel”). As a result, in the case of a slim type reel, stress concentrates on the joint A between the flange body and the flange, and breakage occurs at this point. Therefore, in the case of such a reel, it is necessary to reinforce the joint portion between the flange body portion 02 and the flange 03 in particular.
In the case of a welding reel (assembly reel) configured by welding the flange body portion and the flange, stress (side pressure) cannot be completely absorbed by this welded portion, and thus the degree of damage is extremely high. Therefore, in the case of the reel having such a shape, it is necessary to take measures for preventing damage to the joint portion between the flange body portion and the flange.

  Further, in the case of a reel having a flange diameter L larger than the width H of the flange section (L <H, see FIG. 11, referred to as “body length reel”), it acts on the flange section due to winding tension. The above-mentioned large tightening force is concentrated on the rod body part rather than the flange, and by this tightening force (hereinafter referred to as “winding pressure”), the rod body part is deformed so that the diameter of the center part is reduced (indicated by a dotted line in FIG. 11). This deformation causes both flanges to be deformed so as to collapse inside. Therefore, for the case of such a reel, it is necessary to reinforce the rod body.

Conventionally, a thick steel material having a thickness of about 20 to 50 mm has been used for the reel in order to impart strength that can withstand this lateral pressure and rigidity to the rod body. For this reason, the conventional reel is very heavy, the handling of the reel is very bad, and the transportation cost is also high. In addition, material costs and processing costs were high.
Furthermore, even with such a sturdy reel, the generated side pressure is tremendously large, and thus it is inevitable that the flange and the barrel portion are plastically deformed. Then, after repeated use several times to several tens of times, the deformation of the reel progresses or breaks and becomes unusable.

  The present applicant, as a reel that has taken measures for preventing damage to the joint portion between the flange portion and the flange, has previously been integrated with the cylindrical flange portion and the left and right ends of the flange portion according to Patent Document 1. In the reel for a metal wire body provided with a pair of flanges provided on the inner surface of the flange, the reinforcing body inclined inward by 4 ± 3 ° with respect to the inner surface is welded to the flange inwardly. We have proposed a reel for ultra fine metal wire with tensile stress.

  Moreover, a reel as shown in Patent Document 2 has been proposed as a reel that has been reinforced with respect to the barrel section.

JP 2003-89478 A Japanese Patent Laid-Open No. 11-114798 (page 3, FIG. 1)

  As shown in FIG. 8, the reel 01 for ultrafine metal wire described in Patent Document 1 welds a reinforcing body 04 inclined at 4 ± 3 ° inward to the inner surface 03b of the flange 03 and pulls the flange inward. The structure is provided with tensile stress. The reel for ultra fine metal wire can achieve the effect of reinforcing the reel as described in the publication, but at the time of manufacture, while pressing the vertical surface 04a of the reinforcing body 04 inclined 4 ± 3 ° inward against the inner surface of the flange Since a welding process is required, there is an inconvenience that the cost is high, and there is a problem that the rigidity of the rod body is low.

As shown in FIG. 9, the reel described in Patent Document 2 includes a barrel portion 011 around which a saw wire is wound, flange portions 012 at both ends of the barrel portion 011, and a filler 013 press-fitted into a central hollow portion of the barrel portion 011. And the filler 013 acts to suppress deformation of the reel. Here, the filler 013 is made of a material that is lighter than steel and has compressive strength, and is held by the lid member 014. Reference numeral 015 in FIG. 9 indicates a male screw for fixing the lid member 014 to the end of the flange portion 012.
Even if the barrel portion (cylinder body portion) is tightened by the winding tension of the metal wire rod, the filler 013 press-fitted into the central hollow portion of the barrel portion 011 is used for this metal wire reel. Although the deformation of the barrel portion 011 can be suppressed by acting so as to counteract the above, there is a problem that it is disadvantageous in terms of cost and weight because the structure is complicated and a filler is required. Further, since this reel is a single-piece reel (cut-out reel), it has a structural defect that it is heavy.

  An object of the present invention is to solve the above inconveniences and problems in the above-described conventional reels for metal wire rods, and to produce a very thin metal wire wound having sufficient strength and repeated use while being light and inexpensive. It is to provide a reel reinforcing member for realizing a reel for use, and a metal wire wound reel to which such a reel reinforcing member is attached.

  The present invention is a reinforcing member for a metal wire body winding reel comprising a cylindrical rod body and a pair of flanges integrally provided at both left and right ends of the rod body, The reinforcing member includes a cylindrical main body that can cover substantially the entire surface of the metal rod body of the rod body, and an outer body that is integrally formed at both ends of the main body and substantially the same as the flange of the reel. A pair of flange portions having a diameter and welded to the flange, and residual stress that pulls the flange inward due to welding distortion generated by the welding is generated when the wire is wound on the reel. A structure that acts to counter the generated side pressure is used as a means for solving the problem.

  Further, a reinforcing member for a metal wire body winding reel provided with a cylindrical casing body and a pair of flanges integrally provided at both left and right ends of the casing body, the reinforcing member A cylindrical main body capable of covering substantially the entire surface of the metal rod body of the rod body, a pair of flange-shaped protrusions integrally formed at both ends of the main body, and the reel It has a donut-like planar shape with the same outer diameter as the flange, and its inner peripheral edge is formed by a pair of flange abutting plates welded to the outer peripheral edge of each of the flange-shaped projections and welded to the flange. In addition, the residual stress that pulls the flange inward due to welding distortion generated by welding the flange contact plate to the flange acts to counter the side pressure generated when the wire rod is wound on the reel. Problem solving It is a means.

  Further, a reinforcing member for a metal wire body winding reel provided with a cylindrical casing body and a pair of flanges integrally provided at both left and right ends of the casing body, the reinforcing member A cylindrical main body capable of covering the winding surface of the metal rod body of the rod body, a pair of L-shaped corner contact plates welded to both ends of the main body, and a flange of the reel And a pair of flange application plates that are welded to the flanges and welded to the outer periphery of the vertical part of each corner application plate on the inner peripheral part thereof. And covering the substantially entire surface of the metal rod body winding surface of the flange body with the horizontal portion of the corner contact plate welded to both ends of the main portion and the flange contact plate. Of welding distortion caused by welding to the above flange Cormorants residual stress pulling the flange inwardly, and a means for solving the problems in the configuration acts to oppose the lateral pressure generated when winding the wire to the flange.

  As described above, in the reel of the present invention, the flange portion of the reinforcing member or the flange holding plate is welded to the reel flange, so that the stress that pulls the reel flange inward due to welding distortion generated during welding is applied to the flange portion of the reel. Due to this stress, the reel flange is kept pulled inward even after fabrication. Therefore, the reel welded with the reel reinforcing member of the present invention has an initial stress that pulls the flange portion inward.

  This initial stress acts in a direction that prevents the reel flanges from being spread apart in a direction away from each other due to the side pressure. Therefore, when the metal wire is wound around the reel, the initial stress is caused by the pressure (side pressure) applied to the reel flange. It is possible to suppress the deformation that pushes both the flanges of the reel away from each other. Further, since the flange portion of the reel has a two-layer structure of the flange of the reel and the flange portion of the reinforcing member or the flange contact plate, the rigidity of the flange portion of the reel is increased.

  Since the reel body portion of the reel has a two-layer structure of the reel surface of the reel main body and the cylindrical sleeve plate of the reinforcing member, the rigidity of the reel case body is increased. In addition, when adopting a configuration in which the main part of the reinforcing member is arranged with a gap between the reel body and the winding surface of the reel body, when the metal wire is wound around the reel, the main body of the reinforcing member is tightly tightened on the rod body. When force is applied, the main part of the reinforcing member is elastically deformed freely by the tightening force, and the main part of the reinforcing member absorbs a large part of the large tightening force acting on the rod body part. Due to the large tightening force acting on the case body when winding on the reel, it is possible to prevent the central part of the reel case body from being deformed so as to reduce its diameter, and the durability of the reel can be improved. Can be expected.

  Next, the best mode of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a reinforcing body for a metal wire wound reel as a first embodiment of the present invention together with a reel, and FIG. 2 shows a reinforcing body for a metal wire wound reel as a second embodiment. 3 is a side view of the same, FIG. 4 is a side view of the main part, FIG. 4 is a cross-sectional view of the main part, and FIG. 5 is a cross-sectional view of the reinforcing member for a metal wire wound reel as the third embodiment. 6 is a sectional view of the main part, and FIG. 7 is a perspective view thereof.

  In FIG. 1, reference numeral 10 indicates a metal wire reel, and this metal wire reel 10 is integrally provided on a cylindrical case 1 and on both the left and right sides of the case 1 ( It is composed of flanges 2 and 2 which are welded.

  Reference numeral 5 denotes a main body constituting a reel reinforcing member 20 (hereinafter, also simply referred to as “reinforcing member 20”). The main body 5 covers substantially the entire circumferential surface of the winding surface 1a of the rod body 1. It is composed of a cylindrical body that can be covered. A pair of flange portions 6 having substantially the same outer diameter as the flange 2 of the reel 10 are formed integrally at both ends of the main portion 5 by, for example, welding, and the main portion 5 and the pair of flange portions 6 A reel reinforcing member 20 is configured. In the example shown in FIG. 1, the main body 5 is disposed with a gap a between the winding surface 1a. The reinforcing member 20 may be formed into an integral structure of the main body portion 5 and the pair of flange portions 6 by machining a thick cylindrical material.

In the production stage of the reel 10 (before the flange 2 is attached to the flange body portion 1), the main body portion 5 is fitted from the lateral side (or upper side) of the flange body portion 1, and then the left and right ends of the main body portion 5 are fixed. The reinforcing member 20 can be easily mounted by welding the flange portion 6 to the portion.
When mounted on an existing reel, the main body 5 is formed into a pair of semicircular halves 5A and 5B (see FIGS. 6 and 7), which are respectively formed from the left and right sides of the rod body 1 (or After fitting (from the top and bottom sides), they can be mounted by welding their facing surfaces. The code | symbol 15 of FIG. 6, 7 has shown the weld line of the halves 5A and 5B. In this way, the main body portion 5 is attached to the rod body portion 1. Then, the reinforcing member 20 can be attached to the existing reel by making the flange portion 6 into a half-shaped shape in advance and welding it to both ends of the main portion 5 by the same means as the main portion 5. Reference numerals 3a and 4a in FIG. 7 indicate welding lines. The same applies to the second and third embodiments described below.

  Further, the reinforcing member 20 can be easily removed by the opposite process, so that the reinforcing member 20 can be replaced and the reel can be used semi-permanently.

  After the reinforcing member 20 is disposed on the reel 10 in this way, the flange portion 6 of the reinforcing member 20 and the reel flange 2 are welded 41 to form a structure in which both members are integrated. This welding needs to be a welding in which the stress that pulls the flange of the reel inward due to welding distortion generated at the time of welding remains on the reel until after manufacturing, as an example, as described later, FIG. The case of only spot welding 51 at a plurality of locations on a predetermined radius on the relatively inner diameter side of the flange 2 as shown in FIG. 4 or the spot welding 51 and a relatively outer diameter at a plurality of locations on a predetermined radius on the relatively inner diameter side. A combination of a plurality of spot welds 61 on a predetermined radius on the side is appropriate. In the latter case, the description in the second and third embodiments described later is used for the mutual positional relationship between the two welds.

By welding the flange portion 6 of the reinforcing member 20 to the flange 2 of the reel, a stress that pulls the flange 2 inward due to welding distortion generated during welding remains in the flange portion 6 of the reinforcing member 20. Due to this stress, the flange 2 of the reel 10 is held in a state of being pulled inward even after manufacture. That is, the reel 10 of this embodiment has an initial stress that pulls the flange 2 inward.
This initial stress acts in a direction that prevents the flange 2 of the reel 10 from being pushed and expanded in a direction away from each other due to a lateral pressure. By this action, when a metal wire is wound around the reel 10, the effect of suppressing the deformation that pushes the flanges 2 and 2 of the reel 10 away from each other due to the pressure (side pressure) applied to the flange 2 of the reel 10. Is played. This effect is the maximum effect of the reinforcing member 20.

Further, since the flange portion of the reel 10 has a two-layer structure including the flange 2 of the reel and the flange portion 6 of the reinforcing member, the rigidity of the flange portion of the reel is increased. Since it has a two-layer structure of the winding surface 1a and the cylindrical main portion 5, there is also an effect that the rigidity of the flange portion and the barrel portion of the reel 10 is increased. Further, in the case of this embodiment, the main body portion 6 of the reinforcing member 20 is arranged with a gap a between the winding surface 1a of the reel 10 and therefore, the metal wire is wound around the reel. When a large tightening force is applied to the saddle drum portion, the main body portion 5 of the reinforcing member 20 is freely elastically deformed by the tightening force, and a large part of the large tightening force acting on the saddle drum portion is the main component of the reinforcing member. The portion 5 acts to absorb and prevents the central portion of the reel rod body portion from being deformed by a large tightening force acting on the rod body portion when the metal wire is wound around the reel. And has an attendant effect such that the durability of the reel can be improved.
In this embodiment, the main body 6 of the reinforcing member 20 is arranged with a gap a between the winding surface 1 a of the reel 10, but the main body 6 of the reinforcing member 20 is wound around the reel 10. Even in the configuration in which the surface 1a is closely attached, the effect of increasing the rigidity of the rod body portion of the reel 10 can be obtained.

Next, the second embodiment shown in FIGS. 2 to 4 will be described.
In this embodiment, the reinforcing member 20 has a cylindrical main body 5 that can cover almost the entire surface of the metal filament body 1a of the rod body 1 (the main body 5 has a gap a with respect to the winding surface 1a). Or a pair of flange-like protrusions integrally formed at both ends of the main body 5 and the third embodiment described below). The portion 5a has a donut-like planar shape with the same outer diameter as the flange 2 of the reel 10, and the inner peripheral edge thereof is welded to the outer peripheral edge of each flange-like projection 5a and welded 51 to the flange 2. The residual stress that pulls the flanges 2, 2 inward due to the welding distortion generated by welding the flanges 2 to the flanges 2 is caused by the wrinkles of the wire to the reel 10. Counters side pressure generated during operation And it is configured to act as. In the second embodiment shown in FIGS. 2 and 3, welding of the flange contact plates 7 to the flanges 2 and 2 is performed at the welded portions 51 of the flange-shaped protrusions 5 a and the flange contact plates 7. In addition, further welding 61 may be performed near the outer peripheral edge of each flange 2. In this case, as shown in FIG. 4, the radius x of the substantial part of the flange abutment plate 7 and the outer peripheral radius of each flange-like projection 5a (the main part of the welded portion 51 between the flange abutment plate 7 and the flange-like projection 5a) 5 to 4 and 8 to 2, that is, x: y = 6: 4 to 8: 2 is appropriate for the ratio of the distance from the winding surface of 5 and the rising dimension of the flange-like protrusion 5a. In other words, when the ratio of x and y is 6: 4 to 8: 2, it is possible to achieve the object of the present invention (allowable range), and in particular, it is an experiment that x: y = 7: 3 is best. As a result. This is because if the length of the rising dimension y of the flange-shaped protrusion 5a is out of the allowable range, the effect as a corner reinforcement is reduced, and if the ratio of x is 6 or more, the side pressure absorbing effect is drastically reduced. It is believed that there is.
It goes without saying that even the second embodiment can obtain the same operational effects as those of the first embodiment described above.

Further, a third embodiment shown in FIGS. 5 to 7 will be described.
The reinforcing member of this embodiment is a corner abutting plate 3 (described later) of the winding surface 1a of the casing 1 of the reel 10 (this corner abutting plate 3 is connected to the reel casing 1 of the reel at both ends of the main body 5). It is disposed at a position corresponding to a joint angle portion with the flange 2, that is, a joint portion (a portion indicated by an arrow A in FIG. 10) between the flange body portion 1 and the flange 2, and has an L-shaped cross section and an overall shape in an annular shape. A cylindrical main body 5 that can cover the surface excluding the horizontal portion (the “horizontal portion” means a partial direction parallel to the axis of the main body 5) 3 a and both ends of the main body 5. The inner end of each horizontal portion is welded 31 to a pair of L-shaped corner rest plates 3 and a donut-like planar shape having an outer diameter substantially the same as the flange 2 of the reel 10. The vertical part of each corner backing plate 3, 3 at the peripheral part (“vertical part” is perpendicular to the axis of the main part 5 Refers to the portion) are outer diameter peripheral edge of 3b to be formed by the respective weld 32 is and a pair of flanges patch plate 4 is welded to the inner surface of the flange 2 41. Although it does not specifically limit about the welding to the inner surface of each flange 2 of each flange contact plate 4, FIGS. 5-7 shows the example welded by spot welding.
Also in the reel of this embodiment, the welding 41 can cause the reel 10 to remain in a stress that pulls the reel flange inward due to welding distortion generated at the time of welding by welding each flange backing plate 4 to the flange 2. It can be welded. Due to this stress, the flange 2 of the reel 10 is held in a state of being pulled inward even after manufacture. That is, the reel 10 of this third embodiment has an initial stress that pulls the flange 2 inward.
This initial stress acts in a direction that prevents the flange 2 of the reel 10 from being pushed and expanded in a direction away from each other due to a lateral pressure. By this action, when a metal wire is wound around the reel 10, the effect of suppressing the deformation that pushes the flanges 2 and 2 of the reel 10 away from each other due to the pressure (side pressure) applied to the flange 2 of the reel 10. Is played. This effect is the maximum effect of the reinforcing member 20. In addition, it has the same incidental effect as that of the first embodiment shown in FIG.

  The welding of the reinforcing member 20 and the flange 2 is the welding indicated by the reference numeral 41 as described above, and further welding at the weld (part) 32 between the outer peripheral edge of the corner abutting plates 3 and 3 and the flange abutting plates 4 and 4. May be performed. In this case, it is best that the ratio of the radius x of the substantial portion of the flange backing plate 4 and the rising dimension (vertical dimension) y of the corner backing plate 3 is 7: 3 (that is, x: y = 7: 3). The results were found in the experiment. This is considered to be because the effect as a corner reinforcement body in which the rising dimension y of the corner abutting plate 3 exceeds the above length is reduced, and when the ratio of x is 6 or more, the side pressure absorbing effect is drastically reduced.

  It is desirable to form the inner surface of the bent portion B of the corner abutment plate 3 in a circular arc shape (so-called “R” is added) because stress concentration can be avoided. The same applies to the bent portion of the flange-like protrusion 5a of the second embodiment.

The corner abutment plate 3, the flange abutment plate 4 and the main body 5 are attached to the reel in the same manner as in the first embodiment of FIG.
Note that the corner abutment plate 3 and the flange abutment plate 4 are attached to 1. The flange abutment plate 4 is fixed to the inner surface of the flange. 2. The horizontal edge of the corner abutment plate 3 is welded to the outer edge portion of the main portion 5. 3, it is desirable in terms of work efficiency to carry out in the order of welding 32 to the inner peripheral edge of the flange abutment plate 4 at the vertical edge of the corner abutment plate 3.

In the third embodiment, in addition to the effects described above, the corner abutment plate 3 provided at the joint between the flange body portion 1 and the flange 2 opposes the side pressure acting on the corner abutment plate 3, and its elasticity. However, this greatly contributes to the resilience of the flange 2 centered on the bent portion B of the corner abutment plate 3 and acts to prevent the occurrence of breakage at this location, thereby improving the durability of the reel.
As described above, the configuration in which the flange portion has a two-layer structure, the configuration in which the corner abutment plate 3 is provided at the joint between the flange body 1 and the flange 2, and the edge portion of the vertical portion of the corner abutment plate 3 is the flange abutment plate 4 Due to the structure welded to the inner peripheral edge of the cylinder, the first main body 5 having a function of preventing the central portion of the reel case body from being deformed so as to have a reduced diameter is provided. In the third embodiment, it becomes possible to achieve the deformation or breakage of the reel when the metal wire is wound around the reel, particularly the suppression of the deformation to the inside of the flange and the improvement of the recoverability after unwinding, The durability of the reel can be improved.
