Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, and in particular to a multi-roller positioning frame for straightening steel wire. Background Technology

[0002] In the field of metal processing, steel wire, as an important basic raw material, is widely used in various industries such as construction, machinery manufacturing, automotive, and medical devices. During production, transportation, and storage, steel wire is prone to bending and deformation due to external pressure and its own weight. If used directly in subsequent processing, this will seriously affect the dimensional accuracy, structural strength, and assembly quality of the product. Therefore, steel wire straightening is an indispensable and crucial step in the steel wire processing flow, and the positioning frame, as the core component of steel wire straightening equipment, directly determines the accuracy and efficiency of steel wire straightening.

[0003] During the wire straightening process, height deviation or tilt of the guide wheel will cause uneven stress on the wire, making it impossible to form an effective "bending-reverse bending" stress path. It can only partially eliminate the bending deformation of the wire, making it difficult to meet the requirements of high-precision processing. As a result, the straightened wire still has a certain degree of bending and warping, and secondary straightening is required in subsequent processing, which increases the production process and cost. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-roller positioning frame for straightening steel wires. By adjusting the height of the lifting frame and the position of each guide wheel, stable adaptation can be achieved, eliminating the need for separate positioning frames for steel wires of different specifications and significantly reducing equipment investment costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-roller positioning frame for straightening steel wire includes a mounting frame. A central column is fixedly connected to the inner center of the mounting frame. A lifting block is slidably connected to the inner side of the central column. A first lead screw is threadedly connected to the center of the lifting block. The upper and lower ends of the first lead screw are rotatably connected to the inside of the central column. A first guide wheel is rotatably connected to the front side of the lifting block. Lifting frames are slidably connected to the inner sides of the left and right ends of the mounting frame. A first adjustment groove is provided on the inner side of the lifting frame. A second lead screw is rotatably connected to the inside of the first adjustment groove. A slider is threadedly connected to the outside of the second lead screw. The outer wall of the slider is slidably connected to the inner side of the first adjustment groove. A second guide wheel is rotatably connected to the front side of the slider. A drive assembly for moving the lifting frames up and down is provided at the lower end of the mounting frame.

[0006] Furthermore, a first handwheel is fixedly connected to the top of the first lead screw.

[0007] Furthermore, the lifting frame has a first opening at its end, and a second handwheel is provided inside the first opening. The middle part of the second handwheel is fixedly connected to the end of the second lead screw.

[0008] Furthermore, the lifting frame has sliding grooves at both ends, and a slide rail is slidably connected to the inner side of the sliding groove. The outer wall of the slide rail is fixedly connected to the outer side of the mounting frame and the central column.

[0009] Furthermore, the drive assembly includes second adjustment slots opened at both ends of the upper side of the lower end of the mounting bracket. A threaded block is slidably connected to the inner side of the second adjustment slot. A push rod is rotatably connected to the upper end of the threaded block. A rotating block is rotatably connected to the upper end of the push rod. The upper end of the rotating block is fixedly connected to the lower side of the lifting frame.

[0010] Furthermore, a bidirectional lead screw is rotatably connected to the lower end of the mounting bracket, and the outer walls of the left and right ends of the bidirectional lead screw are threadedly connected to the middle of the threaded block.

[0011] Furthermore, a second opening is provided on the lower right side of the mounting bracket, and a support plate is fixedly connected to the lower side of the second opening.

[0012] Furthermore, a servo motor is fixedly connected to the upper side of the tray, and the drive end of the servo motor is fixedly connected to the middle of the right end of the bidirectional lead screw.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after the servo motor is started, the bidirectional lead screw drives the threaded block to slide in opposite directions. The push rod pushes the lifting frame to move up and down along the slide rail, which can quickly adjust the lifting frame to a height that is suitable for different specifications of steel wire or different processing scenarios. Whether it is fine straightening of thinner steel wire or high-strength straightening of thicker steel wire, stable adaptation can be achieved by adjusting the height of the lifting frame and the position of each guide wheel. There is no need to equip a special positioning frame for different specifications of steel wire, which significantly reduces the equipment investment cost.

[0014] 2. In this utility model, by using the adjustment function of the second handwheel on the second guide wheel, the distance between the second guide wheel and the first guide wheel can be flexibly changed. For steel wires of different diameters, the guide wheel spacing can be quickly adjusted to ensure that the steel wire is stably clamped and guided when passing through, without causing damage to the surface of the steel wire due to excessive clamping. This broadens the adaptability of the device to steel wires of different specifications, improves the versatility and practicality of the equipment, and makes the adjustment more flexible, forming an effective "bending-reverse bending" stress path and improving the straightening effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-4 This utility model provides an embodiment of a multi-roller positioning frame for straightening steel wire, comprising a mounting frame 1, a central column 2 fixedly connected to the inner center of the mounting frame 1, a lifting block 3 slidably connected to the inner side of the central column 2, a first lead screw 4 threadedly connected to the center of the lifting block 3, the upper and lower ends of the first lead screw 4 rotatably connected to the inside of the central column 2, a first guide wheel 5 rotatably connected to the front side of the lifting block 3, and lifting frames 7 slidably connected to the inner sides of the left and right ends of the mounting frame 1, a first adjusting groove 8 provided on the inner side of the lifting frame 7, a second lead screw 9 rotatably connected inside the first adjusting groove 8, and a slider 10 threadedly connected to the outer side of the second lead screw 9. The outer wall of the slider 10 is slidably connected to the inner side of the first adjustment groove 8. The front side of the slider 10 is rotatably connected to the second guide wheel 11. The top of the first lead screw 4 is fixedly connected to the first handwheel 6. The end of the lifting frame 7 is provided with a first opening 12. The inner side of the first opening 12 is provided with a second handwheel 13. The middle part of the second handwheel 13 is fixedly connected to the end of the second lead screw 9. The left and right ends of the lifting frame 7 are provided with sliding grooves 14. The inner side of the sliding groove 14 is slidably connected to a slide rail 15. The outer wall of the slide rail 15 is fixedly connected to the outer side of the mounting frame 1 and the central column 2. The lower end of the mounting frame 1 is provided with a drive assembly for driving the lifting frame 7 to move up and down.

[0019] Rotating the first handwheel 6 at the top of the central column 2 causes the first lead screw 4 to rotate inside the central column 2. Since the first lead screw 4 is threadedly connected to the middle of the lifting block 3 inside the central column 2, and the lifting block 3 slides vertically within the central column 2, the rotating first lead screw 4 drives the lifting block 3 to move up and down along the central column 2. This, in turn, causes the first guide wheel 5 on the front side of the lifting block 3 to rise and fall synchronously until the height of the first guide wheel 5 matches the center height of the steel wire to be straightened. At this point, the first handwheel 6 is stopped, and the second handwheel 13 is then turned through the first opening 12 at the end of the lifting frame 7. Rotate the second lead screw 9 in the first adjustment groove 8 inside the lifting frame 7. The second lead screw 9 is threadedly connected to the slider 10, and the slider 10 is slidably connected in the first adjustment groove 8. The rotating second lead screw 9 will drive the slider 10 to slide up and down along the first adjustment groove 8. The second guide wheel 11 on the front side of the slider 10 will move synchronously to adjust the distance between it and the first guide wheel 5. According to the diameter of the steel wire, adjust the height of each second guide wheel 11 in the lifting frame 7 on the left and right sides so that the steel wire forms an effective "bending-reverse bending" stress path and improves the straightening effect.

[0020] Reference Figures 1-4 The drive assembly includes second adjustment slots 16 on the left and right ends of the upper side of the lower end of the mounting frame 1. A threaded block 21 is slidably connected to the inner side of the second adjustment slot 16. A push rod 22 is rotatably connected to the upper end of the threaded block 21. A rotating block 23 is rotatably connected to the upper end of the push rod 22. The upper end of the rotating block 23 is fixedly connected to the lower side of the lifting frame 7. A bidirectional lead screw 17 is rotatably connected to the lower end of the mounting frame 1. The outer walls of the left and right ends of the bidirectional lead screw 17 are threadedly connected to the middle of the threaded block 21. A second opening 18 is opened on the lower right side of the mounting frame 1. A support plate 19 is fixedly connected to the lower side of the second opening 18. A servo motor 20 is fixedly connected to the upper side of the support plate 19. The drive end of the servo motor 20 is fixedly connected to the middle of the right end of the bidirectional lead screw 17.

[0021] Start the servo motor 20 on the lower support plate 19 of the mounting frame 1. The drive end of the servo motor 20 drives the bidirectional lead screw 17 to rotate inside the lower end of the mounting frame 1. Since the outer walls of the left and right ends of the bidirectional lead screw 17 are threadedly connected to the middle of the threaded block 21 inside the second adjustment groove 16, and the threaded block 21 is slidably connected inside the second adjustment groove 16, the rotating bidirectional lead screw 17 will drive the left and right threaded blocks 21 to slide in opposite directions along the second adjustment groove 16. The upper end of the threaded block 21 is rotatably connected to the rotating block 23 on the lower side of the lifting frame 7 through the push rod 22. When the threaded block 21 moves, the push rod 22 will push or pull the rotating block 23, thereby driving the lifting frame 7 to slide up and down along the slide rail 15 on the outside of the mounting frame 1 and the middle column 2 until the lifting frame 7 is adjusted to a suitable position to match the height of the steel wire. Then, turn off the servo motor 20 to complete the initial adjustment of the height of the lifting frame 7.

[0022] Working principle: The first handwheel 6 drives the first lead screw 4 to rotate. The rotating first lead screw 4 can drive the first guide wheel 5 to move up and down through the lifting block 3, thereby adjusting the height. The servo motor 20 is started to drive the bidirectional lead screw 17 to rotate. The rotating bidirectional lead screw 17 can drive the threaded blocks 21 at both ends to move in opposite directions, thereby driving the push rod 22 to rotate. The push rod 22 pushes the lifting frame 7 to adjust up and down, thereby adjusting the height of the second guide wheel 11. Adjusting the height difference between the second guide wheel 11 and the first guide wheel 5 allows the steel wire to pass between the first guide wheel 5 and the second guide wheel 11, thereby straightening the steel wire. The second handwheel 13 drives the second lead screw 9 to rotate. The rotating second lead screw 9 drives the external slider 10 to move left and right, thereby adjusting the distance between the second guide wheel 11 and the first guide wheel 5.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
