Abstract
Description
Technical Field

[0002] In heavy manufacturing processes such as spiral welded pipe production, welding wire is a critical welding material, and the stability and precision of its feeding process are crucial to welding quality. However, traditional welding wire spools often suffer from problems such as rough workmanship, high resistance, and a tendency for wire to become tangled. These issues can easily lead to defects such as wire jamming during production. Therefore, the industry urgently needs a welding wire spool device that can automatically adjust the welding wire tension and prevent wire tangling and jamming during feeding.
[0003] Chinese patent CN206854820U discloses an automatic telescopic tensioning welding wire spool, comprising a rotating wire spool spindle, a fixed sleeve fixed on the rotating wire spool spindle, at least three telescopic sleeves equally spaced along the radial direction on the fixed sleeve, a welding wire spool support rod slidably disposed in the telescopic sleeve, and the welding wire spool support rod fixedly connected to the welding wire spool groove; the bottom radius of the at least three welding wire spool grooves constitutes the pitch circle inner diameter of the welding wire spool groove; the welding wire spool support rod is connected to a telescopic mechanism, the telescopic mechanism including a connecting rod, a sliding bushing, and a tension adjustment nut, one end of the connecting rod pivotally connected to the welding wire support rod, and the other end pivotally connected to the sliding bushing, the sliding bushing pivotally connected to the tension adjustment nut, and the tension adjustment nut rotatably fitted on the rotating wire spool spindle spindle. The automatic telescopic tensioning welding wire spool can automatically adjust the diameter of the tension pitch circle of the welding wire spool groove, thereby controlling the tension force of the entire welding wire spool, avoiding wire entanglement during wire feeding, and satisfying the requirement of flexible, non-jamming wire delivery from the welding wire spool to the welding gun.
[0004] When using existing automatic telescopic tensioning welding wire reels, the tensioning mechanism in the wire reel may loosen and wear after prolonged use, resulting in low stability of the tensioning force. This makes the welding wire easy to loosen in the wire reel, leading to tangling during the feeding process. Utility Model Content
[0005] This utility model proposes an automatic telescopic tensioning welding wire reel, which solves the problem in related technologies where the tensioning mechanism in the welding wire reel becomes loose and worn after long-term use, resulting in low stability of the tensioning force.

[0016] 1.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1
[0026] like Figures 1-3 As shown, this embodiment proposes an automatic telescopic tensioning welding wire reel, including a support base 1, a power device 4 fixed to the side of the support base 1, a reinforcing component 2 fixed to the other end of the power device 4, and an adjusting component 3 fixed to the side of the power device 4.
[0027] The reinforcement component 2 includes a rotating rod 21, a tensioning slider 22 threadedly connected to the rotating rod 21, a first connecting rod 23 fixed to the side of the tensioning slider 22, a pushing ring 24 fixed to the other end of the first connecting rod 23, a second connecting rod 25 hinged to the side of the pushing ring 24, a reinforcement block 26 hinged to the other end of the second connecting rod 25, an arc-shaped plate 27 fixed to the top of the reinforcement block 26, and the other end of the reinforcement block 26 hinged to the rotating rod 21;
[0028] The rotating rod 21 has a sliding groove 28, and a sliding rod 29 is fixed in the sliding groove 28. The pushing ring 24 is slidably connected on the sliding rod 29. The sliding groove 28 provides directional movement for the pushing ring 24, thereby pushing the reinforcing block 26 to expand outward.
[0029] Four sets of arc plates 27 are provided, and the four sets of arc plates 27 are evenly distributed on the rotating rod 21. The arc plates 27 can reinforce and support the welding wire spool, and can prevent the welding wire spool from being insufficiently tightened when the original tensioning mechanism is unstable.
[0030] A rotating shaft 210 is fixed to the side of the rotating rod 21, and a reinforcing block 26 is hinged to the rotating shaft 210. The reinforcing block 26 rotates in a direction on the rotating rod 21 through the rotating shaft 210, thereby achieving the effect of expansion or contraction.
[0031] The arc plate 27 is at the same height as the tensioning mechanism. The arc plate 27 and the tensioning mechanism contract synchronously. The fact that the arc plate 27 and the tensioning mechanism are at the same height allows the arc plate 27 to expand synchronously, thereby achieving the effect of auxiliary reinforcement of the welding wire spool.
[0032] In this embodiment, the stability of the tensioning mechanism is not high during long-term use, which causes the diameter of the welding wire spool to change. When the tensioning slider 22 moves on the rotating rod 21, it drives the tensioning mechanism to expand. At the same time, the first connecting rod 23 on the side of the tensioning slider 22 pushes the pushing ring 24 to slide in the sliding rod 29, so that the reinforcing block 26 at the other end of the second connecting rod 25 hinged to the side of the pushing ring 24 rotates through the rotating shaft 210, thereby making the reinforcing block 26 expand synchronously with the tensioning mechanism. The arc plate 27 on the top of the reinforcing block 26 contacts the inner wall of the welding wire spool and provides auxiliary reinforcement, thereby preventing the change in the diameter of the welding wire spool caused by the decrease in the stability of the original tensioning mechanism.
[0033] Example 2
[0034] like Figures 4-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the adjustment component 3 includes a wire feeding ring 31, an adjustment groove 32 is provided inside the wire feeding ring 31, an adjustment block 33 is slidably connected in the adjustment groove 32, a third connecting rod 34 is fixed on the outside of the adjustment block 33, and a spring 35 is sleeved on the outside of the third connecting rod 34.
[0035] An adjustment hole 36 is provided on the inner wall of the adjustment groove 32. The third connecting rod 34 is slidably connected in the adjustment hole 36. One end of the spring 35 is fixed to the inner wall of the adjustment groove 32, and the other end of the spring 35 is fixed to the side of the adjustment block 33. The spring 35 allows the adjustment block 33 to be adjusted according to the different diameters of the welding wire. The stationary state of the adjustment block 33 is suitable for the welding wire with the smallest diameter. The third connecting rod 34 is provided with a scale so that the current diameter of the welding wire can be intuitively understood according to the actual movement.
[0036] The adjusting block 33 has inclined surfaces on both sides. The inclined surfaces are mainly used to accommodate welding wires of different diameters, thereby enhancing the adaptability of the wire feeding ring 31.
[0037] In this embodiment, when welding wires of different diameters pass through the wire feeding ring 31, the welding wires contact the adjusting block 33, causing the adjusting block 33 to move and retract into the adjusting groove 32 via the spring 35. This allows the adjusting block 33 to accommodate welding wires of larger diameters. When the adjusting block 33 retracts, the third connecting rod 34 on its side moves outward through the adjusting hole 36, allowing the operator to understand the diameter of the welding wire currently in use, thus achieving the effect of convenient observation.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
