Abstract
Description
Technical Field
[0001] This utility model belongs to the field of guide roller adjustment technology, and in particular relates to a guide roller opening adjustment device. Background Technology
[0002] Guides are key equipment in the metallurgical industry (especially in steel rolling processes). They are mainly used to guide and fix the position of rolled parts (such as billets and plates) during the rolling process, ensuring that they enter or leave the rolls accurately and stably, thereby ensuring the continuity of the rolling process and product quality.
[0003] Currently, there are size differences in rolled products (such as steel billets) from different batches or different process stages. The fixed structure of the funnel-shaped opening can cause larger rolled products to get stuck, while smaller rolled products may deviate or swing.
[0004] To address the aforementioned problems, this application proposes a guide roller opening adjustment device. Utility Model Content
[0005] The purpose of this invention is to provide a guide roller opening adjustment device, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a guide roller opening adjustment device, including a guide and a flared opening at its opening;
[0008] The horn-shaped opening is connected to the guide via a connecting tube at the rear end, and the connecting tube is provided with two opposing right-angle clamps inside.
[0009] The outer side of the connecting cylinder is sleeved on a coaxial outer ring frame, and a worm gear sleeve is rotatably installed inside its front end, which is connected to the worm at the front end of the guide.
[0010] The connecting cylinder has a through-groove running vertically inside. The connecting cylinder also has a first inner ring frame and a second inner ring frame that are coaxial and can move laterally. A transversely spaced adapter frame is rotatably installed between the connecting cylinder and the right-angle clamp, located between the first inner ring frame and the second inner ring frame.
[0011] Preferably, a connecting rod is rotatably mounted on the inner side of the worm gear sleeve, and the first inner ring frame and the second inner ring frame are fixedly connected to the inner sides of the front and rear ends of the connecting rod.
[0012] Preferably, the connecting rod is slidably installed inside the slide groove.
[0013] Preferably, the second inner ring abuts against the left side of the adapter frame located on the left side, and the first inner ring abuts against the right side of the adapter frame located on the right side.
[0014] Preferably, a support is fixed at the outer corner of the right-angle clamp, which is rotatably connected to the movable end of the adapter frame.
[0015] Preferably, a bearing seat is fixed on the inner side of the connecting cylinder, which is rotatably connected to the fixed section of the adapter frame.
[0016] Preferably, the outer rear end of the connecting rod has a slider that is rotatably connected to the outer ring frame.
[0017] This utility model has the following beneficial effects:
[0018] This invention uses a flared mouth combined with a built-in right-angle clamp to form a double-opening structure. By utilizing the outward expansion and inward contraction of the right-angle clamp, the opening size can be adjusted according to the size of the object during insertion and passage, effectively avoiding problems such as increased wear, jamming, and deviation caused by mismatched opening sizes.
[0019] This utility model uses the combination of the first inner ring frame and the second inner ring frame to abut against the transition frame in front of and behind the right-angle clamp, thereby driving the right-angle clamp to move inward and outward as a whole. This ensures that the adjustment dimensions of adjacent right-angle clamps are consistent and that their inner surfaces are always kept horizontal, ensuring that the rolled piece can pass through smoothly.
[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] 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.
[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0034] Please see Figure 1-4 As shown, this utility model is a guide roller opening adjustment device, including a guide 1 and a flared mouth 2 at its opening;
[0035] The horn mouth 2 is connected to the guide 1 through the connecting tube 21 at the rear end. The connecting tube 21 is provided with two pairs of opposing right angle clamps 22, corresponding to the four corners of the horn mouth 2.
[0036] The outer side of the connecting cylinder 21 is sleeved on the coaxial outer ring frame 3, and a worm gear sleeve 31 is rotatably installed inside its front end, which is connected to the worm 11 at the front end of the guide 1. Utilizing the self-locking principle that the lead angle is less than the friction angle, it can form a self-locking mechanism after the worm 11 drives the outer ring frame 3 to move.
[0037] The connecting cylinder 21 has a through-groove 211 inside. The connecting cylinder 21 is equipped with a first inner ring frame 331 and a second inner ring frame 332 that are coaxial and can move laterally. They are distributed in the interior of the connecting cylinder 21 near the front end and the interior of the rear end. The connecting cylinder 21 and the right-angle clamp 22 are rotatably mounted with transversely spaced adapter frames 23 with the same tilt angle. In the initial state, one end of the right-angle clamp 22 is located on the left and the other end is located on the right. Multiple adapter frames 23 are located between the first inner ring frame 331 and the second inner ring frame 332. When the first inner ring frame 331 or the second inner ring frame 332 drives one of the adapter frames 23 to rotate, the multiple adapter frames 23 are affected by the thrust to form a synchronous rotation.
[0038] Furthermore, a connecting rod 32 is rotatably mounted on the inner side of the worm gear sleeve 31. The first inner ring frame 331 and the second inner ring frame 332 are fixedly connected to the inner sides of the front and rear ends of the connecting rod 32. In the initial state, the front end surface maintains a certain distance from the front inner end face of the slide groove 211. This distance provides movement space for the connecting rod 32 and is used to control the rotation angle of the adapter frame 23.
[0039] Furthermore, the connecting rod 32 has two parts, one above the other, which are horizontal plate mechanisms that are slidably installed inside the slide groove 211. The outer rear end of the connecting rod 32 has a slider 321 that is rotatably connected to the outer ring frame 3.
[0040] Furthermore, the second inner ring frame 332 abuts against the left side of the adapter frame 23 located on the left, and the first inner ring frame 331 abuts against the right side of the adapter frame 23 located on the right. When the second inner ring frame 332 slides to the right, it drives the adapter frame 23 to rotate to the right, thereby causing the right angle clamp 22 to retract inward. When the first inner ring frame 331 slides to the left, it drives the adapter frame 23 to rotate to the left, thereby causing the right angle clamp 22 to expand outward.
[0041] Furthermore, a support 221 is fixed at the outer corner of the right-angle clamp 22, and the two sides are protruding rod mechanisms that are rotatably connected to the movable end of the adapter 23. A bearing 212 is fixed on the inner side of the connecting cylinder 21 and is rotatably connected to the fixed section of the adapter 23.
[0042] It is understandable that this utility model can form a double inlet structure at the entrance during use, and the inner inlet can be large or small to adapt to different workpiece sizes, thereby avoiding jamming, increased wear and deviation.
[0043] A specific application of the operation process in this embodiment is as follows: When adjusting the opening size, through the connection between the worm gear sleeve 31 and the worm 11, the worm gear sleeve 31 drives the outer ring frame 3 to slide forward under the rotation of the worm 11, thereby driving the connecting rod 32 to slide forward in the slide groove 211. At this time, the second inner ring frame 332 located on the left side abuts against the left side of the adapter frame 23 located on the left side, thereby driving the adjacent adapter frame 23 to rotate to the right at the same time. This drives the right angle clamp 22 to retract inward towards the center position of the connecting cylinder 21 and maintains the whole in a stable horizontal state, which facilitates the passage of subsequent rolled pieces. In addition, when it is necessary to enlarge the opening, the worm 11 is rotated in the opposite direction so that the 311 on the right side abuts against the right side of the adapter frame 23 on the right side, which drives the right angle clamp 22 to move in the opposite direction, thereby achieving the effect of outward expansion.
