Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel strand production equipment, and specifically to a steel strand straightener. Background Technology
[0002] Steel strand is a steel product made by winding multiple steel wires together. A key step in the production of steel strand is straightening. This straightening process primarily involves using plastic deformation to straighten the steel strand and other wires. Straightening equipment is required to ensure the straightness of the steel strand.
[0003] The straightening device applies force to the steel strand after it has been laid out, gradually straightening it to prevent quality problems during subsequent use. Existing straightening devices typically have two rows of guide rollers, one front and one rear. The steel strand passes between these rollers, and the gap between the front and rear guide rollers can be adjusted according to the thickness of the strand, thus achieving longitudinal adjustment. However, the following shortcomings remain: In actual production, to avoid the guide rollers being too far apart or too close in the lateral direction, adjustment is needed. However, the lateral spacing of the guide rollers in existing straightening devices is fixed, making lateral adjustment inconvenient. Summary of the Invention
[0004] To address the problem that existing straighteners are not convenient for lateral adjustment, this invention proposes a steel strand straightener that allows the guide wheel to move both longitudinally and laterally, better meeting actual production needs. It features convenient adjustment and strong adaptability.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A steel strand straightener includes a base plate, with a support first and a support second disposed on the top of the base plate. Above the base plate are two rows of parallel-arranged guide wheels first and guide wheels second. The device also includes a lateral adjustment assembly located between the support first and support second. The lateral adjustment assembly includes a slider first, a slider second, and a connecting rod assembly. The connecting rod assembly is connected to the slider first and slider second. Several sliders first are arranged at equal intervals, and the guide wheels second are mounted on the sliders first. Several sliders second are also arranged at equal intervals, with each slider first and slider second alternating. The guide wheels first are mounted on the sliders second via a longitudinal adjustment assembly.
[0007] A main screw and a guide rod are horizontally connected between slider one and slider two. Both slider one and slider two have through holes. The main screw passes through the through holes of slider one and slider two. Both slider one and slider two are slidably connected to the guide rod. A fixing block is provided in the through hole of slider one, which is located on the far left. The fixing block is threadedly connected to the main screw.
[0008] Furthermore, the linkage assembly includes several connecting rods 1, which are hinged together sequentially from left to right. The two outermost connecting rods 1 are each hinged to a connecting rod 2 at one end. The length of the connecting rod 2 is half the length of the connecting rod 1. One end of one connecting rod 2 is hinged to a support 2, and one end of the other connecting rod 2 is hinged to the leftmost slider 1. The middle portion of each connecting rod 1 is hinged to both slider 1 and slider 2. After the connecting rods 1 and 2 are connected, they form multiple identical V-shapes arranged in the transverse direction. During movement, the V-shapes remain identical, thus ensuring that the sliders connected to each connecting rod are equidistantly arranged, achieving equal-interval adjustment.
[0009] Furthermore, the number of guide wheels two is one more than the number of guide wheels one, and both guide wheels one and guide wheels two have annular wire grooves on their outer circumferential surfaces. A channel is formed between the wire grooves of guide wheels one and guide wheels two, through which the steel strand passes.
[0010] Furthermore, the second slider has a U-shaped groove, and the longitudinal adjustment component includes a sliding seat that is slidably installed inside the U-shaped groove. A rotating shaft is fixed to the top of the sliding seat, and a guide wheel is rotatably mounted on the rotating shaft. A secondary screw is threadedly connected to the inside of the sliding seat, and the secondary screw is rotatably connected to the bottom of the U-shaped groove.
[0011] Furthermore, a baffle is installed at the opening of the U-shaped groove, and a through hole is formed in the center of the baffle. The secondary screw passes through the through hole of the baffle and is fixedly connected to a polygonal prism. The polygonal prism can be used to match a wrench or a socket.
[0012] Furthermore, a rotating shaft is fixed to the top of the slider one, and the guide wheel two is rotatably mounted on the rotating shaft two. A shaft hole is formed at the center of both the guide wheel one and the guide wheel two. The rotating shaft one is inserted into the shaft hole of the guide wheel one, and the rotating shaft two is inserted into the shaft hole of the guide wheel two.
[0013] Furthermore, one end of the main screw passes through the bracket and is fixedly connected to a handle, while the other end of the main screw is rotatably connected to the bracket. The handle facilitates manual rotation of the main screw.
[0014] Furthermore, there are two guide rods, which are arranged parallel to each other and symmetrically distributed on both sides of the main screw. The guide rods are used for the sliding of slider one and slider two, avoiding misalignment and dislocation.
[0015] The beneficial effects of this utility model through the above technical solution are as follows:
[0016] This invention features both a lateral adjustment component and a longitudinal adjustment component. On one hand, when the main screw rotates, the fixed block is threadedly connected to the main screw, and the leftmost slider moves towards or away from the support. During this movement, the leftmost slider drives the connecting rod assembly. Specifically, connecting rod one and connecting rod two form multiple identical V-shapes arranged laterally. These V-shapes remain identical during movement, ensuring that the sliders connected to each connecting rod are equidistantly arranged, achieving equal-space adjustment. On the other hand, when the auxiliary screw rotates, the sliding seat is threadedly connected to the auxiliary screw and moves along the U-shaped groove, adjusting its position. This allows the guide wheel to move towards or away from the guide wheel two according to the thickness of the steel strand, achieving longitudinal adjustment. Therefore, the guide wheel can move both longitudinally and laterally. Compared with existing technologies, this invention has a novel and unique structure, is simple and reasonable, and features convenient adjustment and strong adaptability. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0027] like Figures 1-7 As shown, this embodiment provides a steel strand straightener, including a base plate 1. A first bracket 2 and a second bracket 3 are disposed on the top of the base plate 1. Two rows of parallel guide wheels 4 and 5 are disposed above the base plate 1. The assembly also includes a lateral adjustment component located between the first bracket 2 and the second bracket 3. The lateral adjustment component includes a first slider 6, a second slider 7, and a connecting rod assembly. The connecting rod assembly is connected to the first slider 6 and the second slider 7. Several first sliders 6 are arranged at equal intervals. The second guide wheels 5 are mounted on the first sliders 6. The second sliders 7 are arranged as follows: Several sliders are arranged at equal intervals, with each slider 6 and slider 7 alternating. The guide wheel 4 is mounted on the slider 7 via a longitudinal adjustment assembly. Furthermore, a main screw 8 and a guide rod 9 are horizontally arranged between sliders 6 and 7. Both sliders 6 and 7 have through holes. The main screw 8 passes through the through holes 21 of sliders 6 and 7. Both sliders 6 and 7 are slidably connected to the guide rod 9. A fixing block 22 is provided in the through hole 21 of the leftmost slider 6. The fixing block 22 is threadedly connected to the main screw 8.
[0028] It is worth mentioning that, in this embodiment, the inner diameter of the through hole 21 is larger than the outer diameter of the main screw 8, so that the slider 6 will not rub against the main screw 8 during its movement.
[0029] With the above-described structure, when the main screw 8 rotates and moves the leftmost slider 6, the connecting rod assembly moves the remaining sliders 6 and 7, making the change in distance between adjacent sliders 6 and 7 equal. This achieves equal spacing adjustment of guide wheels 4 and 5 in the lateral direction. Furthermore, by setting a longitudinal adjustment component, the spacing adjustment of guide wheels 4 and 5 in the longitudinal direction is achieved.
[0030] Specifically, please refer to again Figure 2The linkage assembly includes several connecting rods 10, which are hinged together sequentially from left to right. The two outermost connecting rods 10 are each hinged to a connecting rod 2 11 at one end. The length of connecting rod 2 11 is half the length of connecting rod 10. One end of one connecting rod 2 11 is hinged to a bracket 2 3, and one end of the other connecting rod 2 11 is hinged to the leftmost slider 6. The middle portions of connecting rods 10 are hinged to slider 6 and slider 2 7, respectively. Both connecting rods 10 and 2 11 are straight rods. When connected, they form multiple identical V-shapes arranged laterally. During movement, the V-shapes remain identical, thus ensuring that the sliders connected to each connecting rod are equidistantly arranged, achieving equal-interval adjustment.
[0031] In this example, the number of guide wheels 2 5 is one more than the number of guide wheels 1 4. Both guide wheels 1 4 and guide wheels 2 5 have annular wire grooves 12 on their outer peripheral surfaces. A channel is formed between the wire grooves 12 of guide wheels 1 4 and guide wheels 2 5, through which the steel strand body 23 passes, thereby achieving a straightening effect.
[0032] Please refer to it again. Figure 3 and Figure 4 The slider 7 has a U-shaped groove 13. The longitudinal adjustment assembly includes a sliding seat 14 that is slidably installed inside the U-shaped groove 13. A rotating shaft 15 is fixed to the top of the sliding seat 14. The guide wheel 4 is rotatably mounted on the rotating shaft 15. A secondary screw 16 is threadedly connected to the inside of the sliding seat 14. The secondary screw 16 is rotatably connected to the bottom of the U-shaped groove 13.
[0033] Furthermore, a baffle 17 is installed at the opening of the U-shaped groove 13. A through hole is formed in the center of the baffle 17. The auxiliary screw 16 passes through the end of the through hole in the baffle 17 and is fixedly connected to a polygonal prism 18. By setting the polygonal prism 18, a wrench or socket can be matched. When the auxiliary screw 16 is rotated by rotating the polygonal prism 18 with a wrench, the sliding seat 14 is threadedly connected to the auxiliary screw 16. The sliding seat 14 moves along the U-shaped groove 13, thereby adjusting the position of the sliding seat 14. Thus, depending on the thickness of the steel strand, the guide wheel 4 moves away from or closer to the guide wheel 5, thereby achieving the purpose of longitudinal adjustment.
[0034] In this embodiment, the top of the slider 6 is fixed with a rotating shaft 19, and the guide wheel 5 is rotatably mounted on the rotating shaft 19. A shaft hole is formed at the center of both the guide wheel 4 and the guide wheel 5. The rotating shaft 15 is inserted into the shaft hole of the guide wheel 4, and the rotating shaft 19 is inserted into the shaft hole of the guide wheel 5.
[0035] To facilitate manual rotation of the main screw 8, one end of the main screw 8 passes through the bracket 2 and is fixedly connected to a handle 20, while the other end of the main screw 8 is rotatably connected to the bracket 3.
[0036] In this embodiment, there are two guide rods 9, which are arranged parallel to each other and symmetrically distributed on both sides of the main screw 8. The guide rods 9 are used for the sliding of slider 6 and slider 7, avoiding misalignment and dislocation.
[0037] The working principle of this utility model is as follows:
[0038] By setting a lateral adjustment component, when the main screw 8 rotates, the fixing block 22 is threadedly connected to the main screw 8, and the leftmost slider 6 moves towards or away from the bracket 3. During the movement of the leftmost slider 6, the connecting rod assembly is driven to move. Specifically, after the connecting rod 10 and connecting rod 21 are connected, they form multiple identical V-shapes arranged in the lateral direction. During the movement of the connecting rod assembly, the V-shapes remain the same. Therefore, it can be ensured that the sliders connected to each connecting rod are arranged at equal intervals, and equal interval adjustment is achieved. When the interval between the guide wheels in the lateral direction reaches the preset distance, the main screw 8 stops rotating.
[0039] By setting up a longitudinal adjustment component, when the multi-faceted prism 18 is rotated by a wrench, the auxiliary screw 16 is rotated. The sliding seat 14 is threadedly connected to the auxiliary screw 16, and the sliding seat 14 moves along the U-shaped groove 13, thereby adjusting the position of the sliding seat 14. Thus, depending on the thickness of the steel strand, the guide wheel 1 4 moves away from or closer to the guide wheel 2 5, thereby achieving the purpose of longitudinal adjustment.
[0040] In summary, this utility model enables the guide wheel to move both longitudinally and laterally, which can better meet actual production needs and has the characteristics of convenient adjustment and strong adaptability.
[0041] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
