Description

  The present invention relates to a reel for a metal wire body having a mounting shaft for a rotating shaft inside a winding drum and steel plate flanges at both ends, and in particular, a metal wire body such as a steel cord wire, a steel cord, a saw wire (hereinafter referred to as a steel wire). (Referred to simply as a wire).

  In general, this type of reel winds a wire made of an ultrafine hard steel wire such as a steel cord wire having a wire diameter of about 0.15 to 0.40 mm or a saw wire having a wire diameter of about 0.12 to 0.16 mm, Used to feed out. When such a wire is wound by a predetermined weight, a large winding pressure (clamping force) and a side pressure (pushing and expanding force) are applied to the flange of the reel due to the winding tension and winding weight of the wire. These winding pressures and lateral pressures increase geometrically as the wire diameter decreases, the winding pitch becomes dense, the winding tension increases, and the winding weight increases.

  In addition, reels for saw wires, etc. are taken up by a wire manufacturer → taken up while cutting a hard material by a user → disconnected and newly taken up by a wire manufacturer → while cutting a hard material by a user Winding → Used repeatedly by wire manufacturers for wire breaking and new winding.

  Therefore, this type of reel has, as a characteristic, not only that the winding drum has strength and rigidity against the winding pressure, but also the flange with sufficient strength against side pressure and bending due to the side pressure (outside of both flanges). Rigidity with less warping (perpendicularity in which peripheral portions are pushed away in directions away from each other) is required. This is because the flexure of the flange gradually increases with repeated use, causing deformation of the winding drum, which leads to hunting when winding the wire and causes disconnection.

Therefore, in order to have strength and rigidity with respect to the winding pressure and the side pressure and to reduce the weight, a reel made of a high-tensile steel plate has been developed and used (for example, Patent Document 1). Further, in order to improve the strength of the flange, a reel in which a reinforcing disk provided with a rib loosely fitted on the rib is mounted on the outer side of the flange provided with a radially bulging rib has been developed and used. (For example, Patent Document 2)
JP 2001-206636 A JP 2003-267634 A

  Patent Document 1 is a reel in which a plurality of ribs extending in the longitudinal direction are provided in parallel on a winding drum. In the third page, column 4, lines 25 to 31 of the publication, for example, SAFC (cold-rolled high-tensile steel plate), SAPH (hot-rolled high-tensile steel plate) and the like are suitable as the material of the winding drum. For example, SAPH (hot rolled high strength steel plate), SPCC (cold rolled high strength steel plate), etc. are suitable as the material of the flange, and structural carbon steel such as S45C is used as the material of the winding drum and flange. It is described that it may be.

  Patent Document 2 differs from the present invention in its subject, but the conventional reel B is shown in the second page, column 1, line 20 to line 28, as shown in FIGS. 3 (a) and 3 (b). The flanges 11, 11 are attached to both ends of the winding drum 10, and the reinforcing disks 12, 12 are attached to the central portion outside the flanges 11, and the flanges 11, 11 and the reinforcing disks 12, 12 are used for reinforcement. What provided the rib 11a, 11a ..., 12a, 12a ... is disclosed.

  The reels of Patent Documents 1 and 2 can sufficiently cope with a certain amount of winding weight in terms of strength and rigidity. Today, the wire is further reduced in diameter, and the winding conditions such as winding tension and pitch by the wire manufacturer and / or user are becoming severe, and the side pressure on the flange tends to increase. is there.

  Therefore, the present invention further improves the strength against the expansion of the flange and the rigidity against the bending so that even when a wire having a smaller diameter is wound under severe conditions, it can sufficiently withstand the applied side pressure. The problem is to increase the number of times of use only by slightly increasing the amount of flange expansion even after repeated use.

  The reel of the present invention is a wire reel provided with a rotating shaft mounting tube inside the winding drum and steel plate flanges at both ends, and a main body flange having the flange fixed to both ends of the winding drum, A hollow structure is formed by a reinforcing flange provided so as to cover the end face of the main body flange.

  In this reel, since the flange has a hollow structure, the strength against the expansion of the flange and the rigidity against the deflection are increased.

  In the present invention, on the end face of the main body flange, a plurality of ribs bulging outward are provided in a substantially radial manner at equal intervals, and the top surface of the rib is in contact with the inner surface of the reinforcing flange in the radial direction. Is preferred. With this configuration, the rib acts as a kind of streak of the hollow structure, and the strength and rigidity of the flange are further increased.

  In the present invention, it is preferable that the length of the mounting pipe is larger than the width of the winding drum, and the mounting hole edges provided in the central portion of the reinforcing flange are fixed to both ends of the mounting pipe. If it does in this way, since the fixation location of the center part of a reinforcement flange is located outside the fixation location of a main body flange, the intensity | strength and rigidity of a flange are raised further.

  When the reel of the present invention is used, the strength against the expansion of the flange and the rigidity against the flexure are increased. Therefore, even if a wire having a smaller diameter is wound under a severe winding condition, The amount of flange expansion can be halved and the number of repeated uses can be increased compared to a single flange or a reel provided with a reinforcing disk on the outside of the flange.

  Embodiments will be described below with reference to the drawings.

  1 (a) and 1 (b), a reel A includes a winding drum 1, a mounting tube 2 arranged in the longitudinal direction of the winding drum 1, and a body flange 4 and reinforcements at both ends of the winding drum 1 and the mounting tube 2. The flange 5 is composed of flanges 3 and 3 provided so that the flange portion has a hollow structure.

  The winding drum 1 and the mounting tube 2 are each made from a steel tube having a predetermined diameter and length. Each length is such that the winding cylinder 1 is smaller than the attachment tube 2, and both ends of the attachment tube 2 are located outside the both ends of the winding drum 1.

  The main body flange 4 is formed by press-working a high-tensile steel plate, and has a fitting portion 4a at the center portion, a curled portion 4b at the outer peripheral edge portion, and an outward bulge on the end surface around the fitting portion 4a. A plurality (6 to 12) of ribs 4c are formed. The main body flange 4 is firmly fixed by spot welding at a plurality of locations by fitting the fitting portions 4 a inside the both ends of the winding drum 1. The rib 4c may be omitted.

  The reinforcing flange 5 is formed by press-working a high-tensile steel plate, and is formed by forming an attachment hole edge 5a in the center portion. The reinforcing flange 5 is formed by caulking the attachment hole edge 5a to the end of the attachment tube 2 and fitting the outer peripheral portion into the curled portion 4b of the main body flange 4, or on the top surface of the rib 4c of the main body flange 4. Spot weld the abutted part and firmly fix it. The flange 3 has a hollow structure with a flange portion of the main body flange 4 and the reinforcing flange 5.

  Incidentally, in the reel configuration, a reinforcing plate 6 made of a steel plate having a fitting portion with the winding drum 1 at the central portion may be attached to the inner surface of the main body flange 4. With such a configuration, it is possible to prevent the wire from falling into the rib 4c and to reinforce the corner portion that is a fastening portion between the main body flange 4 and the winding drum 1.

  Although the steel drum was used for the winding drum 1 and the attachment pipe 2, a steel plate bent may be used. Moreover, as a material, for example, cold-rolled high-tensile steel plate (SAFC), carbon steel pipe for machine structure (STKM), carbon steel for machine structure (S45C), etc. can be used.

  The main body flange 4 and the reinforcing flange 5 are made of high-tensile steel plates. For example, cold-rolled high-tensile steel plates (SAPC, SPCC) and hot-rolled high-tensile steel plates (SAPH) can be appropriately selected and used.

  The thicknesses of the main body flange 4 and the reinforcing flange 5 are preferably set so that the main body flange is smaller than the reinforcing flange in consideration of strength and rigidity against the side pressure.

  Furthermore, the reinforcement flange 5 can further increase the strength against expansion of the flange and the rigidity against deflection when the peripheral portion of the mounting hole edge 5a is bulged outward to form the reinforcement bulge portion 5b.
