Technical Field

[0002] Metal wire rods or coils, copper, aluminum, conductors and other materials supplied in the same form are also collectively referred to as wire. Metal wire needs to be tensile tested after processing and forming to ensure the required structural strength of the metal wire.

[0003] Existing tension detection devices mostly use two clamps to clamp the two ends of the wire when fixing the wire. Since different wire materials have different hardness, when using the clamp to clamp one end of the metal wire, it is easy for the clamping force to be too small, causing it to fall off, or the clamping force to be too large, causing the wire to be compressed and deformed, affecting its own structural strength, and thus affecting the subsequent wire tension detection.

[0004] Therefore, a wire tension detection device is proposed. Utility Model Content

[0007] Preferably, the cross-sections of the upper winding wheel and the lower winding wheel are both I-shaped structures.

[0009] Preferably, the fixed limit hole and the movable limit hole are located on different circumferential radii with the same center.

[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a wire tension detection device. Figure 1-4 As shown, it includes a fixing frame 1, the top of the fixing frame 1 is fixedly connected to a hydraulic cylinder 2 by bolts, the hydraulic cylinder 2 is fixedly connected to a lifting plate 3 through an output end on one side thereof, the bottom center position of the lifting plate 3 is fixedly connected to a tension sensor 4 by screws, the bottom of the tension sensor 4 is fixedly connected to a support frame 5 by screws, an upper winding wheel 6 is rotatably connected to an inner wall of one side of the support frame 5, a lower winding wheel 7 is rotatably connected to an inner wall of one side of the fixing frame 1 near the lower position of the upper winding wheel 6, a first threading hole 8 and a second threading hole 9 are provided on the inner wall of one side of the upper winding wheel 6 and the lower winding wheel 7, the first threading hole 8 is located on one side of the second threading hole 9, the upper winding wheel 6 and the lower winding wheel 7 are provided with a first threading hole 8 and a second threading hole 9, the first threading hole 8 is located on one side of the second threading hole 9, and the upper winding wheel 6 and the lower winding wheel 7 are provided with a first threading hole 8 and a second threading hole 9. A rotating rod 10 is welded at the central position of the outer wall of one side of the winding wheel 7, and a handwheel 11 is integrally formed at one end of the rotating rod 10. A dynamic limit hole 12 is provided on the outer wall of the rotating rod 10, and a rod sleeve 13 is welded on the outer wall of the fixed frame 1 and the support frame 5 near the outer position of the rotating rod 10. The rotating rod 10 passes through the rod sleeve 13, and a fixed limit hole 14 is provided on the outer wall of the rod sleeve 13. The inside of the fixed limit hole 14 passes through the limit rod 15, and a through groove 16 is provided on the outer wall of one side of the fixed frame 1 near the side of the support frame 5. The rod sleeve 13 on the support frame 5 passes through the through groove 16, and the inside of the first threading hole 8 and the second threading hole 9 are penetrated by metal wire 17.

[0023] It should be noted that, since the existing tension detection device is prone to the problem of the clamping force being too small and causing it to fall off, or the clamping force being too large and causing the wire to be compressed and deformed, affecting its own structural strength, and thus affecting the subsequent detection of the wire tension, this embodiment, through the setting of the first threading hole 8 and the second threading hole 9, can make one end of the metal wire 17 be set in a U shape and then squeezed by the subsequent winding of the metal wire 17, and the extrusion friction force after winding is used to fix one end of the metal wire 17, thereby avoiding the problem that the two ends of the metal wire 17 are prone to falling off or the structural strength is damaged when clamped by traditional clamps, ensuring the stability of the positions of the two ends of the metal wire 17 during tension detection, and ensuring the integrity of the metal wire 17's own structure, thereby improving the accuracy of the tension detection of the metal wire 17.

[0024] Specifically, in this embodiment, this scheme mainly includes an upper winding wheel 6 and a lower winding wheel 7. When the tension of the metal wire 17 is tested, the two ends of the metal wire 17 are passed through the first threading hole 8 on the inner wall of the upper winding wheel 6 and the lower winding wheel 7 respectively, and pass through the second threading hole 9. At this time, the hand wheel 11 is turned, and under the transmission of the rotating rod 10, the upper winding wheel 6 or the lower winding wheel 7 at one end of the rotating rod 10 rotates synchronously. As the upper winding wheel 6 and the lower winding wheel 7 rotate, the upper winding wheel 6 and the lower winding wheel 7 reel the metal wire 17, and the metal wire 17 squeezes and reels each other. When the upper winding wheel 6 and the lower winding wheel 7 are wound, the metal wire 17 is wound. After the wheel 7 rotates more than five times, the limit rod 15 is inserted through the fixed limit hole 14 into the dynamic limit hole 12 on the rotating rod 10 to realize the positioning and fixation of the rod sleeve 13 and the rotating rod 10. The hydraulic cylinder 2 is controlled to drive the lifting plate 3 to move upward through the output end on one side. The tension sensor 4 and the support frame 5 at the bottom of the lifting plate 3 move upward synchronously, and the upper winding wheel 6 and the lower winding wheel 7 move in opposite directions. The metal wire 17 between the upper winding wheel 6 and the lower winding wheel 7 is pulled, and the metal wire 17 is subjected to tension detection under the action of tension. The tension sensor 4 detects the tension value and displays the tension value on an external display screen.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the cross-sections of the upper winding wheel 6 and the lower winding wheel 7 are both I-shaped structures.

[0026] In this embodiment, the “I”-shaped upper winding wheel 6 and the lower winding wheel 7 can limit the metal wire 17 during the winding process to prevent the metal wire 17 from falling off the upper winding wheel 6 and the lower winding wheel 7.

[0027] In a further preferred embodiment of the present invention, Figure 1-3As shown, the fixed limit hole 14 and the dynamic limit hole 12 are located on different circumferential radii with the same center. A rod head is provided at one end of the limit rod 15, and the cross section of the limit rod 15 is a T-shaped structure. The limit rod 15 passes through the fixed limit hole 14 and is embedded in the inside of the dynamic limit hole 12.

[0028] In this embodiment, by using the fixed limit hole 14 and the dynamic limit hole 12 on the same circle center but different circumferential radii, the limit rod 15 can pass through the fixed limit hole 14 and then be inserted into the dynamic limit hole 12, thereby realizing the positioning and fixation of the rod sleeve 13 and the rotating rod 10.

[0029] In a further preferred embodiment of the present invention, Figure 4 As shown, the metal wire 17 is arranged in a U shape inside the first threading hole 8 and the second threading hole 9.

[0030] In this embodiment, the metal wire 17 passing through in a U-shape can enable the subsequently wound metal wire 17 to be squeezed onto the metal wire 17 passing through in a U-shape.
