Description
Technical Field
[0001] This utility model relates to the technical field of steel wire drawing process, and in particular to an unwinding device for steel wire production. Background Technology
[0002] Wire drawing is a processing technique widely used in industries such as steel, non-ferrous metals, and plastics. Specifically, wire drawing is a plastic processing method that applies tension to a metal billet, forcing it through a die to obtain a product of a specific shape and size.
[0003] In steel wire drawing production lines, uncoiling equipment is needed to unwind coiled steel wire online. Existing uncoiling equipment, such as the steel wire uncoiling device disclosed in patent publication number CN222754092U, includes a connecting seat, a turntable, a support cylinder, a separator bar, a cylinder, and a turntable drive mechanism. One side of the connecting seat is hinged to the turntable, and several separator bars are distributed on the top of the turntable. The support cylinder is vertically arranged on the turntable. Limiting components are provided on both sides of the turntable and at the hinge point with the connecting seat. An improved steel wire drawing device disclosed in patent publication number CN215032404U includes a base, the top of which is rotatably connected to an improved steel wire roller. The top of the base is fixedly connected to a fixed frame. Two rows of symmetrically arranged guide roller groups are fixedly connected inside the fixed frame. Through holes are opened on both the left and right sides of the fixed frame, and a guide frame is fixedly connected to the left side of the fixed frame.
[0004] The existing wire unwinding equipment has the following defects: Since the wire is wound on the unwinding frame, it is pulled away from the unwinding frame directly by the traction end. At this time, it is easy to pull out the upper and lower layers of wire together, which can cause the wire to get stuck. In addition, the wire is easy to bounce to the nearby operators when it is pulled out of the unwinding frame. Moreover, the wire will bend and deform greatly under the action of traction force and then be released by sticking to the unwinding frame, which will have a significant impact on the internal structure of the wire.

One end of the steel wire located on the wire feeding frame passes through the guide block, the guide wheel and the interior of the hollow column in sequence.
[0010] Optionally, the guide frame includes a first fixing ring and a second fixing ring arranged sequentially along the direction from the baffle towards the shaft seat. The first fixing ring is fixed to the outside of the hollow column.

[0028] Example 1
[0029] Reference Figure 1This utility model discloses an unwinding device for steel wire production, comprising: a support base 1; a hollow column 2 horizontally rotatably connected to the support base 1; a wire feeding frame 3 rotatably connected to the end of the hollow column 2 away from the support base 1; a limiting member 4 disposed at the bottom of the wire feeding frame 3; a guide frame 5 disposed on the outer wall of the rotating column; and one end of the steel wire located on the wire feeding frame 3 passing through the guide frame 5 and the interior of the hollow column 2 in sequence before extending out of the exterior of the hollow column 2.
[0030] Using the above structure, by adjusting the limiting member 4 away from the wire feeding frame 3, the wire feeding frame 3 is supported by the hollow column 2, and the wire roll can be placed on the wire feeding frame 3. Then, the limiting member 4 is controlled to restrict the wire feeding frame 3, so that the hollow column 2 is controlled to rotate in the opposite direction to the winding of the wire roll. At this time, the wire feeding frame 3 does not rotate. The end of the wire extending out of the hollow column 2 is subjected to the traction force of the subsequent wire pulling device, so that one end of the wire roll passes through the guide frame 5 and the interior of the hollow column 2 in sequence and then extends out of the exterior of the hollow column 2. In this way, the wire roll is sequentially fed out, the feeding is safe and reliable, and this feeding method will not have a significant impact on the internal structure of the wire.
[0031] Combination Figure 2 In detail, in this embodiment, a bearing seat 6 is fixed to the top of the support base 1. One end of the hollow column 2 is connected to the interior of the bearing seat 6. The wire feeding frame 3 includes a stop 301. The end of the hollow column 2 away from the bearing seat 6 is connected to the interior of one side of the stop 301 via a bearing 302. Multiple wire feeding rods 303 are fixed to the other side of the stop 301. One end of the hollow column 2 is connected to the bearing seat 6 via a bearing, allowing it to rotate within the bearing seat 6. The other end of the hollow column 2 is connected to the stop 301 via a bearing, allowing the hollow column 2 to rotate while the stop 301 does not rotate during wire feeding. The multiple wire feeding rods 303 facilitate the placement of wire rolls. The wire rolls can be moved horizontally to one side of the stop 301 along with one end of the wire feeding rod 303. The maximum diameter of the stop 301 is larger than the diameter of the wire roll, allowing the stop 301 to limit the wire rolls placed on the wire feeding rods 303 on one side.
[0032] Combination Figure 3 In detail, in this embodiment, a through hole 7 is opened on the outer wall of the hollow column 2 near the shaft seat 6. A guide wheel 8 is connected to one end of the through hole 7 near the shaft seat 6, and a guide block 9 is fixed to the other end of the through hole 7. One end of the steel wire located on the wire feeder 3 passes through the guide block 9, the guide wheel 8, and the interior of the hollow column 2 in sequence. The arrangement of the guide block 9 and the guide wheel 8 enables one end of the steel wire passing through the guide frame 5 to be guided to the internal axis of the hollow column 2 through the guide block 9 and the guide wheel 8, and to extend from the inside to the outside from one end of the hollow column 2.
[0033] Reference Figure 2In detail, in this embodiment, the guide frame 5 includes a first fixing ring 501 and a second fixing ring 502 arranged sequentially along the direction from the baffle 301 toward the shaft seat 6. The first fixing ring 501 is fixed to the outside of the hollow column 2. It should be noted that in order to guide one end of the steel wire that passes around the baffle 201 into the interior of the hollow column 2, at least one set of fixing rings and supports on the fixing rings is provided. In this embodiment, two sets are provided, namely the first fixing ring 501 and the second fixing ring 502. A first support 503 is fixed to one side wall of the first fixing ring 501, and the second fixing ring 502... A second bracket 504 is fixed to one side wall of the 2. A wire guide wheel set 505 is fixed on the first bracket 503, the second bracket 504 and the shaft seat 6. One end of the wire on the wire feeder 3 passes around the baffle 301 and through the wire guide wheel set 505 on the first bracket 503. The first fixing ring 501 and the second fixing ring 502 are arranged sequentially along the baffle 301 toward the shaft seat 6, with the lengths decreasing sequentially. The wire guide wheel set 505 is set to restrict the position of the wire movement and ensure that the end of the wire that crosses the baffle 301 is smoothly guided into the interior of the hollow column 2.
[0034] Among them, such as Figure 1 and Figure 2 As shown, although the structures of the first bracket 503, the second bracket 504, and the line-blocking wheel assembly 505 on the bearing 6 are slightly different, they are all composed of a wheel seat 505a, a vertical guide wheel 505c, and a horizontal guide wheel 505b. For example... Figure 4 The wire guide wheel assembly 505 includes a wheel base 505a, on which two parallel horizontal guide wheels 505b are rotatably connected, and two parallel vertical guide wheels 505c are also rotatably connected. The horizontal guide wheels 505b are vertically positioned to one side of the vertical guide wheels 505c. The wheel base 505a serves as a base for fixing the wire. The arrangement of the two horizontal guide wheels 505b and the two vertical guide wheels 505c allows the steel wire located between the two horizontal guide wheels 505b and the two vertical guide wheels 505c to be smoothly guided from the wire coil into the interior of the hollow column 2.
[0035] Reference Figure 1 and Figure 2 In detail, in this embodiment, a first counterweight 10 is fixed to the side wall of the first fixing ring 501 away from the first support 503, and a second counterweight 11 is fixed to the side wall of the second fixing ring 502 away from the second support 504. Since both the first support 503 and the second support 504 are located on one side of the hollow column 2, the arrangement of the first counterweight 10 and the second counterweight 11 can ensure the smooth rotation of the hollow column 2.
[0036] Example 2
[0037] Combination Figure 5Based on the same concept as in Embodiment 1 above, the unwinding equipment for steel wire production also includes four wire feeding rods 303 fixed on the side of the baffle 301 away from the hollow column 2. The limiting member 4 includes a limiting seat 401 located below the wire feeding rods 303. A telescopic cylinder 402 is fixed on the top of the limiting seat 401. A limiting block 403 is fixed at the telescopic end of the telescopic cylinder 402. Inclined surfaces 404 located between two adjacent wire feeding rods 303 are provided on both sides of the limiting block 403. The two upper wire-feeding rods 303 serve as the support for the wire coil. The two lower wire-feeding rods 303 ensure that the baffle 301 will not rotate when the hollow column 2 rotates, provided that the limiting block 403 is positioned between the two wire-feeding rods 303. The telescopic cylinder 402 can be a pneumatic cylinder or an electric telescopic rod. By controlling the telescopic cylinder 402 to move the limiting block 403 up and down, the limiting block 403 restricts the wire-feeding rods 303 when it moves up, and facilitates the placement of the wire coil to be fed onto the wire-feeding rods when it moves down. After the limiting block 403 moves down, the baffle 301 is supported by the hollow column 2. The wire coil to be fed enters through one end of the wire-feeding rod 303 and moves to one side of the baffle 301. Then, the limiting block 403 is controlled to move up to restrict the wire-feeding rod 303, and then the wire feeding operation is carried out. The inclined surfaces 404 on both sides of the limiting block 403 enable the limiting block 403 to stably restrict the two wire feeding rods 303 below, preventing the wire feeding rods 303 from shaking after being restricted.
[0038] Example 3
[0039] Combination Figure 6 Based on the same concept as in Embodiment 1, this unwinding device for steel wire production also includes a drive motor 12. A first pulley 13 is fixedly fitted onto the output end of the drive motor 12. A second pulley 14 is fixedly fitted onto the outside of the hollow column 2 located between the shaft seat 6 and the through hole 7. A transmission belt 15 connects the first pulley 13 and the second pulley 14. The rotation of the hollow column 2 can be achieved in the above manner. Specifically, the drive motor 12 is started, and the drive motor 12 drives the hollow column 2 to rotate via the first pulley 13, the second pulley 14, and the transmission belt 15. It should be noted that the rotation direction of the drive motor 12 should be determined according to the winding method of the steel wire coil after it is placed on the unwinding rod 303. For example, if the steel wire coil itself is wound counterclockwise, then the drive motor 12 should control the rotation direction of the hollow column 2 to be counterclockwise, thus achieving effective unwinding of the steel wire.
[0040] Working principle:
[0041] The telescopic cylinder 402 is controlled to move the limiting block 403 downward. The wire coil to be released enters through one end of the release rod 303 and moves to one side of the baffle 301. Then, the limiting block 403 is controlled to move upward to restrict the release rod 303. After one end of the wire coil passes around the baffle 301, it passes sequentially through the wire-blocking wheel group 505 on the first bracket 503, the wire-blocking wheel group 505 on the second bracket 504, the guide block 9 and the guide wheel 8 to the interior of the hollow column 2. Then, it is connected to the subsequent wire pulling device through the wire-blocking wheel group 505 on the shaft seat 6. At the same time as the traction force of the subsequent wire pulling device is applied, the drive motor 12 is started. The drive motor 12 drives the hollow column 2 to rotate through the first pulley 13, the second pulley 14 and the transmission belt 15. The rotation of the hollow column 2 will drive the wire coil to release the wire. The released wire is finally transported to the subsequent wire pulling device for processing.
[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
