Abstract

A reel for metal wire, having flanges made of steel plate, wherein reinforcing sections are arranged around core holes (107) in flanges (102), where the reinforcing sections are each formed by integrating a substantially radial side-surface reinforcing section (108) and a ring-like core-hole-periphery reinforcing section (109). This construction reduces the weight of the reel while enhancing the rigidity and strength of the flanges (102). It is preferable that the side-surface reinforcing section (108) be of a dovetail shape whose width is wider on the reel center side. Further, it is preferable that a flange (102) be of a multiply layered construction, with a hollow-ring-like flange-peripheral-edge reinforcing section (111) provided in the peripheral edge of the flange (102). Further, a winding drum (101) may be made of steel plate, in which case the drum is joined to the flanges (102) as by forming weld build-ups in through-holes (104).

Description

Reel for metal wire

Technical field

TECHNICAL FIELD [0001] The present invention relates to a reel for a metal filament, and in particular, a reel for winding a wire for a tire cord.

The present invention relates to a reel for a metal wire body suitable as a reel around which a large amount of ultrafine metal wire body is wound, such as a reel for winding a saw wire for a wire saw.

Background art

[0002] A reel for a metal wire body wound with an ultrafine metal wire body such as a wire of a tire cord or the like has a flange at both ends of the case body. Generally, the case body and the flange are structural carbon steel ( For example, it is made of thick steel such as S45C). In this way, the reel for the metal filament body in which the casing and the flanges at both ends are made of thick-walled steel are manufactured according to the manufacturing method. The reel and the flange and flange are manufactured separately from the thick steel member, and the welding reel integrated by welding or the flange and flange are manufactured separately from the thick steel member and bolted together. They are classified as assembly reels (see, for example, JP-A-2002-370152 and JP-A-11 114798). However, when these reels made of thick steel are used for extra-fine metal filaments, it is necessary to further increase the thickness of the cylinder and flange so as to ensure sufficient strength and rigidity. Reinforcement of the joint between the cylinder and the flange and reinforcement of the cylinder may be necessary, and the weight of the reel becomes extremely large, handling is poor, transportation costs are high, and material costs and cover costs are high. It will be a thing.

[0003] By the way, these reels for metal striates are used as the strands of ultra-fine metal wires having a wire diameter of less than 0.2 mm, for example, steel cords (tire cords) for reinforcing rubber products. Wire diameter 0.15-0. 40mm extra fine metal wire or steel cord, wire saw extra fine metal wire (saw wire) 0.12-0. 4-1. When winding on a reel at 5kg), a large winding pressure (tightening force) acts on the barrel due to the brazing tension, and the side pressure ( (Expanding force) acts. And the wire diameter of the metal filament to wind is The smaller the winding pitch, the higher the winding tension, the greater the winding tension, and the greater the number of winding reciprocations, the faster the winding pressure (clamping force) acting on the cylinder and the side pressure (push-out force) acting on the flange. To increase.

[0004] For this reason, a reel on which such a fine metal wire is wound has a sufficient strength against the winding pressure (clamping force) by the casing and against the elongation caused by the side pressure expanding the flange. The flange must have sufficient strength against the side pressure and less stiff due to the side pressure. The bending of the flange due to the side pressure causes deformation (dentation) of the cylinder, and the deformation of the cylinder leads to hunting when the wire is taken up and causes disconnection.

[0005] In particular, in the case of a "slim type reel" in which the diameter of the flange portion is larger than the width of the rod cylinder, the pressure (side pressure) applied to the flange portion is far more than the winding pressure applied to the rod cylinder. For this reason, the pressure force exerted on the flange is expanded in the direction of separating the two flanges on the outer peripheral side. And the side pressure is several tons when winding 40-60kg or more of saw wire, like a reel for wire saws, can reach several tens of tons, As a result, stress concentrates on the corner where the flange and flange are connected, and damage is likely to occur at this point. On the other hand, in the case of the “long-reel-long reel” in which the width of the rod cylinder is larger than the diameter of the flange, the pressure caused by the winding tension concentrates on the rod cylinder, and the winding pressure (clamping force) acting on the rod cylinder increases. Then, due to this large winding pressure (tightening force), the cylinder is deformed so that the diameter of the central portion is reduced, and due to this deformation, the reel is deformed so that both flange portions are collapsed inward. In the case of such a reel, damage is likely to occur to the casing.

[0006] For this reason, the conventional one-piece reel, welding reel or assembly reel has a thickness of the steel material of the cylinder and flange so that sufficient strength and rigidity can be secured when winding an extra fine metal wire. — As thick as about 50 mm, the reel itself became very heavy, the handling of the reel became worse, and the material cost and processing cost were high, which led to high transportation costs. In addition, even if the thickness of the steel material of the cylinder and the flange is increased as described above, in the case of the slim type reel, it is necessary to further reinforce the joint part between the cylinder and the flange. Reinforcement of the torso was necessary. [0007] In particular, in the case of a single-piece reel, the rigidity is high and it can withstand repeated use. However, because it is overhanging, the material cost and processing cost are high, and the total weight is due to the solid structure. Will increase.

[0008] In addition, in the case of an assembly reel coupled with bolts, each part can be formed by forging or the like, so that the material cost and processing cost can be reduced, and the hollow structure can be reduced in weight. Due to the side pressure (push-out force) generated due to the winding tension at the time, a gap is created between the flange and the case drum, and the metal wire body bites into the gap.

[0009] On the other hand, since the welding reel can have a hollow structure, the material cost and processing cost can be reduced, the weight can be reduced, and the force can be integrated by welding. There is no problem that there is a gap between the cylinders and the wire bites. However, even in the case of a welding reel, in order to secure strength and rigidity against winding pressure (clamping force) and side pressure (push-out force), a thick steel pipe is used for the barrel or a thick steel plate is bent. It is necessary to use a cylinder that has been processed into a cylindrical shape, and the flange must also be a thick steel plate. In addition, the welded portion between the flange and the flange portion cannot absorb the stress (side pressure) completely, so the degree of damage is extremely high. Therefore, in the case of welding reels, it was necessary to take measures to reinforce the case and flange and to prevent damage to the joint between the case and flange.

[0010] As described above, the conventional one-piece reel, welding reel, or assembly reel made of thick steel plate is a metal wire reel, particularly a wire rod for a tire cord, and an extra fine metal wire used for a wire saw. It was impossible to achieve weight reduction while ensuring sufficient strength and rigidity as a reel for the body.

[0011] Therefore, as a reel for a metal filament body that can achieve light weight while ensuring strength and rigidity, a plurality of reinforcing ribs that swell radially outward are formed by pressing a high-strength steel plate. At the same time, a reel (see, for example, Japanese Patent Laid-Open No. 9-295768) was developed in which a flange formed by folding the periphery to form a hollow ring-shaped periphery reinforcing portion was fixed to both ends of the cylinder by welding. Both the body and flange are manufactured separately as members having rib-like reinforcement structures by press forming of high-tensile steel plates, and they are spot-welded. As a result, a press reel (for example, see Japanese Patent Application Laid-Open No. 2001-206636) has been developed.

[0012] As described above, a reel provided with a plurality of reinforcing ribs swelled radially outward by pressing a high-strength steel plate is fixed to both ends of the rod barrel by welding, The press reel, in which the body part and flange part are both manufactured separately by high-strength steel sheet press working and welded together, is lightweight, and the wire of the tire cord is very fine metal wire such as saw wire. In the case of winding, it is possible to cope sufficiently with a certain degree of strength and rigidity in terms of strength and rigidity. However, these reels have a problem with the rigidity of the flange formed by press working. In particular, the pressure (side pressure) applied to the flange is large, and the pressure pushes the flanges at both ends in a direction that separates from each other on the outer peripheral side. When acting in the direction of expansion, the flange is greatly deformed, and stress is concentrated on the corner portion where it is connected to the casing, and damage is likely to occur.

[0013] Furthermore, in the press reel, there is a risk that the flange peripheral portion may be deformed by an impact such as a brim between the reels when the reel is transferred, and when the flange peripheral portion is deformed, the balance is lost, This can lead to deformation of the entire reel when winding or unwinding the filament, causing hunting and other factors. For this reason, flanges manufactured by press carriage usually have a hollow ring-shaped reinforcement structure with the peripheral part folded back in a curl shape, but the hollow part may still dent when the reels hit each other. Can't fully prevent the deformation! /.

[0014] Further, the press reel is particularly lightweight, and when winding an extremely fine metal wire body such as a wire of a tire cord or a saw wire, it can cope with a winding weight of up to about 30 kg in terms of strength and rigidity. Force With the conventional press reel structure, when winding a V or extra fine metal wire with a wire diameter of less than 0.2 mm, if the winding weight force is 0-60 kg or more, it cannot cope with strength. . In this case, if the thickness of the steel sheet forming the flange and flange of the press reel is increased, the strength and rigidity are increased. However, since conventional press reels spot weld the press-molded cylinder and flange at the corner where the cylinder and flange meet, the combined thickness of the cylinder and flange is limited to about 6 mm. If the thickness is larger than that, spot welding becomes impossible. Therefore, the conventional process With a less reel, there was a limit to increasing the thickness of the steel sheet in response to an increase in winding weight. In addition, instead of spot welding, as with conventional welding reels that also have thick steel material force, if you try to weld the entire corner of the corner by arc welding, the entire corner of the reel with a thickness of several millimeters will be arced. If it is welded, the reel will be distorted due to the heat effect during welding, which will cause a runout when the reel rotates, making it unusable for practical use!

[0015] In addition, the conventional press reel has a hollow ring-shaped peripheral reinforcing portion formed by folding back the peripheral edge of the flange in order to prevent deformation of the peripheral edge of the flange due to impacts such as brim between reels during transfer. Because the flange surface inside the reel axial direction of the flange is rounded at the peripheral edge due to the substantially circular cross section, the substantially flat part is reduced by that amount. Metal wire can be wound, but the amount of winding is reduced.

Problems to be solved by the invention

[0016] Therefore, the main object of the present invention is to increase the rigidity and strength against the expansion of the flange when the metal filament is wound in the reel for a metal filament having a steel plate flange.

[0017] Another object of the present invention is to prevent deformation of the peripheral edge of the flange due to an impact of a reel for a metal filament having a steel plate flange.

[0018] It is another object of the present invention to increase the strength of a reel for a metal filament body in which a rod body portion and a flange portion are integrated by welding so as to cope with an increase in winding weight. .

[0019] Further, according to the present invention, a metal filament can be wound up to the full flange periphery by being wound on a metal filament reel having a steel plate flange provided with a hollow ring-shaped peripheral reinforcement. The purpose is to scrub.

Means for solving the problem

[0020] In order to achieve the above object, the present invention has a flange formed of a steel plate fixed to both ends of the casing, and each flange has a core hole formed at the center thereof, and a substantially radial shape around the core hole. To reel A plurality of side reinforcements bulging outward in the axial direction are formed, and the plurality of side reinforcements bulge outward in the axial direction of the reel in a ring shape continuously with the side reinforcements along the core hole. Provided is a reel for a metal wire body in which a core hole periphery reinforcing portion that constitutes a reinforcing portion integrated with the portion is formed. The reel includes a plurality of side reinforcing portions bulging substantially radially around the core hole of the flange, and a core hole peripheral reinforcing portion bulging in a ring shape along the core hole continuously to the plurality of side reinforcing portions. Constitutes an integral reinforcement with high rigidity, which increases the rigidity and strength against flange expansion. Therefore, light weight can be achieved while ensuring sufficient strength and rigidity as a reel for ultrafine metal filaments.

[0021] In the above-mentioned reel for metal filaments, each side reinforcing part is preferably a divergent shape in which the width in the circumferential direction of the flange increases on the reel center side. Such a configuration can further increase the rigidity of the flange against expansion.

[0022] Further, in the above-mentioned reel for metal filaments, each flange has a multiple structure in which a plurality of flange members that also have steel plate force are arranged so as to overlap in the axial direction, and is integrated with the first flange member on the outer side in the axial direction. A second flange member on the inner side in the axial direction overlaps at the peripheral portion, and the overlapping peripheral portion is folded back to the outer side in the reel axial direction over the entire periphery to form a hollow ring-shaped flange peripheral reinforcing portion. It is good to do. By doing so, a flange structure that increases the rigidity and strength of the entire flange while making the inner surface of the flange (the flange surface inside the reel axial direction) flat (substantially flat), and the flanges of the reels at the time of transportation are hit. It is possible to prevent deformation of the peripheral edge of the flange due to impact such as. Further, by providing such a reinforcing portion at the flange peripheral portion, the strength and rigidity of the entire flange are increased, and deformation of the flange when the metal wire is wound can be suppressed.

[0023] Further, in the reel for a metal filament, the peripheral portions of the first flange member and the second flange member that constitute the flange peripheral reinforcing portion are such that the peripheral portion of the first flange member is a ring with respect to the flange radial direction. The peripheral edge of the second flange member is folded back approximately 90 degrees outward in the axial direction, and the peripheral portion of the second flange member is folded back approximately 180 degrees outward in the ring axial direction with respect to the flange radial direction. It is assumed that the peripheral part of the first flange part with the part folded back approximately 90 degrees is wound in a substantially tight contact state from the outside in the radial direction of the flange. Is good. By doing so, the strength and rigidity of the peripheral edge of the flange can be increased while reducing the weight of the reel.

[0024] Further, in the above-mentioned reel for metal filaments, each flange has a flange-shaped reinforcing portion in the form of a hollow ring on the periphery, and the flange surface on the inner side in the reel axial direction that is continuous with the flange-periphery reinforcing portion. It is preferable that the flange peripheral reinforcing portion is substantially planar and is folded substantially perpendicularly to the outside in the reel axial direction with respect to the substantially planar flange surface. By doing so, it is possible to wind the metal wire body to the full flange periphery.

[0025] The reel for the metal striate body has a cylindrical body member in which the rod body also has a steel plate force, and each flange is connected in a cylindrical shape so as to be fitted to the inner circumferences of both ends of the body member. At the both ends of the body member, through holes are formed at predetermined intervals in the circumferential direction at positions overlapping the cylindrical connecting portions of the flanges. The body may be thickened by welding from the outside in the radial direction, and the body member and each flange may be joined and joined together by the body. With this configuration, it is possible to weld the body member and the flange together by welding even if the thickness of the steel sheet is increased so as to increase the strength and rigidity of the body member. Reel distortion due to the heat effect of the time can be prevented.

[0026] That is, this reel for metal wire rods is formed by welding the casing and flange to the through hole on the casing side in a form of being overfilled. Since it is possible to weld to a thickness that is difficult to weld, compared to conventional press reels, where the barrel and flange are joined by spot welding, the thickness of the steel plate is increased, and strength and rigidity are increased to accommodate increased winding weight You can do that. Also, by reducing the thickness of the steel sheet used, it is possible to reduce the weight of the reel. The welding force is also welded at a predetermined interval in the circumferential direction rather than arc welding the entire circumference of the flange and flange corners as in the conventional welding reel, so the reel is distorted by the thermal effect during welding. There is no such thing. Through holes for welding (in the embodiment described later, it is set to 12.) For example, 8-16 to ₀

The invention's effect

[0027] As described above, according to the present invention, it is possible to increase the rigidity and strength against the expansion of the flange while reducing the weight of the reel for the metal filament having the steel plate flange. The

[0028] Further, while reducing the weight, the strength and rigidity of the metal filament reel can be increased to cope with an increase in winding weight, and the reel can be prevented from being distorted by heat during welding. Togashi.

[0029] Further, in the reel for a metal filament having a steel plate flange provided with a hollow ring-shaped peripheral edge reinforcing portion, the inner surface of the flange can be substantially planar up to the full periphery, and the full flange periphery can be obtained. It becomes possible to wind a metal wire body.

[0030] Further, it is possible to prevent deformation by increasing the strength of the flange peripheral portion against impact, and the flange when the metal wire is wound with the flange peripheral reinforcing portion increasing the strength and rigidity of the entire flange. The deformation of can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments will be described with reference to the drawings.

1 and 2 show a first example of the embodiment. Figure 1 shows the longitudinal section of the reel (in Figure 2).

Fig. 2 is a front view of a linole.

[0033] The reel of this embodiment is a reel for metal wire used for a wire drawing machine, a twisting machine, or a wire saw for a tire cord, and includes a rod body 101 and flanges positioned at both ends thereof.

102, 102.

The rod cylinder 101 is constituted by a cylindrical drum member 103. The body member 103 is manufactured by, for example, bending a cold-rolled high-tensile steel plate (SAFC) into a cylindrical shape, and a plurality of body members 103 at regular intervals in the circumferential direction (12 in the illustrated example). The force can be changed as appropriate, and is preferably 8-16.) Through-holes 104 are formed.

[0035] Further, the flanges 102, 102 at both ends include, for example, a first flange member 105 and a second flange member 106 obtained by separately press-forming hot-rolled high-tensile steel plates (SAPH), and the first flange member 105. And the second flange member 106 as the inner side, and are integrated in an axially overlapping arrangement.

[0036] The first flange member 105 has a core hole 107 formed in the center thereof, and a plurality of (in the example shown in the figure) bulges radially around the core hole 107 toward the flange outer surface side (axially outer side). There are eight, but can be changed as appropriate, preferably 6-12. Along the core hole 107, the peripheral reinforcing portion of the core hole that bulges out in the form of a ring continuously to the outer surface side of the flange along the plurality of side reinforcing portions 108 and forms an integral reinforcing portion together with the plurality of side reinforcing portions 108 109 is formed. The plurality of side reinforcing portions 108 have the same shape and the same size as each other. As shown in FIG. 2, each of the side reinforcing portions 108 has a divergent shape in which the width in the circumferential direction of the flange increases toward the center of the reel when viewed in the reel axial direction. As shown in FIG. 3, the bulge height toward the flange outer surface side in the flange radial direction is substantially uniform and is formed at substantially equal intervals in the flange circumferential direction.

[0037] On the other hand, the second flange member 106 is formed in a substantially flat circular donut shape so as to constitute the inner surface of the flange 102. The cylindrical connecting portion 110 is fitted into the inner periphery of the end portion.

[0038] In each of the flanges 102, 102, the first flange member 105 on the outer side in the axial direction and the second flange member 106 on the inner side in the axial direction overlap at the peripheral part, and the peripheral part of the first flange member 105 is the entire circumference. Folded approximately 90 degrees outward from the flange axial direction with respect to the flange radial direction, and the peripheral partial force of the second flange member 106 is folded outward from the reel axial direction with respect to the flange radial direction over the entire circumference from the first flange member 105 The second flange is folded at a substantially right angle over the entire circumference, then curled inward in the radial direction, wrapped around the periphery of the first flange member 105, and then folded back approximately 90 degrees, and the entire flange was folded back approximately 180 degrees. Peripheral part force of member 106 The peripheral part of the first flange member 105 folded back approximately 90 degrees is wound in a close contact state from the outside in the flange radial direction, and the edges thereof are plural at regular intervals in the circumferential direction. It is welded to the flat portion of the first flange member 105 at the location w (8 locations in the example shown, but can be changed as appropriate, preferably 6 to 12 locations). A flange peripheral reinforcing portion 111 is formed.

[0039] The core pipe 112 is arranged inside the body member 103 constituting the rod body 101, and the cylindrical connecting portions 110, 110 of the second flange members 106, 106 of both flanges 102, 102 are arranged. The flanges 102 and 102 are assembled so that they fit into the inner periphery of the end of the member 103 and pass through the core holes 107 of the first flange members 105 and 105 so that both ends of the core noise 112 are fitted. . Then, the both ends of the core pipe 112 are squeezed to fix the end surfaces of the flanges 102 and 102 (the outer surfaces of the first flange members 105 and 105), and arc to the through holes 104 formed at both ends of the body member 103. By applying the fleshing by welding, the rod body 101 and each franc 102 and 102 are joined and joined together. Then the grinder is cut on the meat and the surface is flattened.

[0040] The left and right flanges 102, 102 are provided on the core hole peripheral reinforcing portion 109 of the first flange member 105 with a pair of bore holes 113, 114 for rotation start, with the phases shifted by 90 degrees from each other. ing.

[0041] As a material of the body member 103 constituting the rod body 101, SAPH (hot rolled high strength steel sheet) and the like are suitable in addition to SAFC (cold rolled high strength steel sheet). As materials for the first flange member 105 and the second flange member 106, in addition to SAPH (hot rolled high strength steel plate), SPCC (cold rolled high strength steel plate) and the like are suitable. Further, the material of the barrel part 1 and the flange part 2 may be structural carbon steel such as S45C.

[0042] The reel of this embodiment includes a plurality of side reinforcing portions 108 bulging radially around the core hole 107 of the first flange member 105 of the flanges 102, 102, and the plurality of side reinforcing portions 1 08. The core hole peripheral reinforcing part 109 continuously swelled in a ring shape along the core hole 107 constitutes a highly rigid integrated reinforcing part, so that the rigidity and strength against the expansion of the flanges 102 and 102 are increased. Therefore, it is possible to achieve a light weight while ensuring sufficient strength and rigidity as a reel for ultrafine metal filaments. In particular, each side reinforcing part 108 has a divergent shape in which the width in the circumferential direction of the flange is increased at the center side of the reel, so that the rigidity of the flanges 102 and 102 with respect to expansion is ensured and light weight is more effective. Can be achieved.

[0043] Further, this reel has a multiple structure in which the first flange member 105 on the outer side in the axial direction and the second flange member 106 on the inner side in the axial direction overlap each other at the peripheral portion as described above. By forming the hollow ring-shaped flange peripheral reinforcement portion 111 by folding back the entire circumference, the flange inner surface (the flange surface inside the reel axis direction) can be made flat (substantially flat), and the flange The strength and rigidity of the peripheral edge are increased. In addition, since the strength against impact is increased, it is possible to prevent deformation of the peripheral edge of the flange due to, for example, the brim of the reels during reel transfer. Further, the flange peripheral reinforcing portion 111 increases the strength and rigidity of the flanges 102 and 102 as a whole, and the deformation of the flanges 102 and 102 when the metal wire body is wound can be suppressed. The flange periphery reinforcing portion 111 is the first frame. The peripheral portion of the flange member 105 is folded back by about 90 degrees, and only the second flange member 106 is folded back by about 180 degrees, and the weight can be reduced because it is not a complete double structure.

[0044] And, this reel has the flange peripheral portion 111, 111 force of the flanges 102, 102, and the S-reel is folded back to the outside in the axial direction at a substantially right angle, and the inner side surfaces of the flanges 102, 102 are substantially flat to the full periphery. Because of this flange surface, it is possible to wrap the metal wire to the full edge of the flange.

In this reel, through holes 104 are formed at both end portions of the body member 103 of the case body 101, and the body member 103 and the flange 102 are formed by applying a radially outward force to the through holes 104 by welding. , 102 are joined together, and the body member 103 and the flanges 102, 102 can be joined together by welding even if the thickness of the steel plate of the body member 103 is increased. Therefore, it is possible to increase the thickness and strength of the steel sheet, and since welding is performed at a predetermined interval, distortion of the reel due to the heat effect during welding can be prevented.

It should be noted that the present invention is not limited to the above-described embodiments, and it is needless to say that the embodiments can be appropriately modified within the scope of the technical idea of the invention.

[0047] The reel of the present invention is not limited to tire cord strands and saw wires, and can be widely applied as a reel for winding various metal wire strips.
