Description

Technical Field

[0001] This utility model belongs to the field of guidance technology, and in particular relates to a correction and anti-deviation guidance assembly. Background Technology

[0002] Round steel rolling guides are key equipment used to guide and stabilize round steel (such as round bars and rods) during the steel rolling process. Their main functions include guiding the steel to enter and leave the rolls correctly, stabilizing the rolling process to prevent deviation or twisting, adjusting the guide in time when the rolled piece deviates from the predetermined path to ensure it runs in the correct position, and improving product quality by reducing surface defects and dimensional errors.

[0003] In existing guides, the guide wheels are arranged in pairs, symmetrically on the side of the steel. However, conventional guides only have two sets of guide wheels in two positions, one for vertical and one for horizontal alignment. If the steel has a small degree of curvature, the two sets of guide wheels in different directions cannot accurately align the steel, resulting in larger errors during some high-precision machining. Secondly, the guide wheels on existing guides can only be adjusted individually, and the accuracy and coordination need to be improved, making it impossible to achieve synchronous adjustment between multiple sets of guide wheels.

[0004] To address the aforementioned issues, this application proposes a corrective anti-deviation guide assembly. Utility Model Content

[0005] The purpose of this invention is to provide a corrective anti-deviation guide assembly that 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 correction and anti-deviation guide assembly, including a support cylinder, a sliding adjustment cylinder fitted on the outside of the support cylinder, and two sets of first guide wheels and two sets of second guide wheels arranged in pairs inside the support cylinder. Each set of first guide wheels and second guide wheels is arranged in a cross shape, and the two sets of first guide wheels and two sets of second guide wheels are spaced apart. A rotating shaft is provided in the guide wheel, and the two ends of the shaft pass through the support cylinder and the adjustment cylinder at the same axial direction and can slide at the through position.

[0008] Furthermore, the support cylinder is provided with a through adjusting sleeve, and the adjusting cylinder is provided with a through driving sleeve. The adjusting sleeve is perpendicular to the steel rolling conveying path, and the driving sleeve and the adjusting sleeve are inclined to each other. The end of the shaft slides simultaneously in the adjusting sleeve and the driving sleeve.

[0009] Furthermore, the adjusting cylinder has fixed threaded sleeves in the middle of both sides, and the supporting cylinder has rotating screws on both sides through brackets. The threaded sleeves are threadedly connected to the screws, and the adjusting cylinder slides outside the supporting cylinder through the threads of the screws and the threaded sleeves.

[0010] Furthermore, a pressing platform is fixedly provided at the upper end of the adjusting cylinder, and a pressing bolt is threadedly connected to the pressing platform. The bottom of the pressing bolt faces the outer surface of the support cylinder, and the pressing bolt is pressed against the outside of the support cylinder by the screw of the pressing platform.

[0011] Furthermore, the support cylinder has a tapered inlet guide plate on one side and a tapered outlet guide plate on the other side, with the tapered directions of the inlet guide plate and the outlet guide plate being consistent.

[0012] Furthermore, mounting bases are fixed at both ends of the bottom of the support cylinder, and mounting holes are provided in the mounting bases.

[0013] This utility model has the following beneficial effects:

[0014] This utility model sets up four sets of spaced guides, with the guides in two directions arranged in a cross pattern. Each pair of guides corrects the rolling process in one direction. The guide wheel groups spaced in the same direction can correct the rolling process over a wider range while ensuring the overall volume of the device. The multiple sets of guide wheels work together to prevent the rolling process from deviating when the rolling process is fed into the equipment.

[0015] This invention places the shaft in the adjusting sleeve and the driving sleeve, and then adjusts the position of all guide wheels simultaneously by sliding the adjusting cylinder outside the supporting cylinder. This makes the operation more convenient and the synchronous adjustment more precise, without producing obvious errors.

[0016] 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

[0025] 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.

[0026] 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.

[0027] Please see Figure 1 - Figure 5 As shown, this utility model is a correction and anti-deviation guide assembly, including a support cylinder 1, a sliding adjustment cylinder 2 fitted outside the support cylinder 1, and two sets of first guide wheels 3 and two sets of second guide wheels 4 arranged in pairs inside the support cylinder 1. Each set of first guide wheels 3 and second guide wheels 4 is arranged in a cross shape, and the two sets of first guide wheels 3 and two sets of second guide wheels 4 are spaced apart. A rotating shaft 5 is provided in the guide wheel, and the two ends of the shaft 5 pass through the support cylinder 1 and the adjustment cylinder 2 at the same axial end and can slide at the through position. In this embodiment, by setting four sets of spaced guides, the guides in two directions are arranged in a cross shape. Each pair of sets corrects the rolling steel in one direction. The spaced guide wheel groups in the same direction can correct the rolling steel over a larger range while ensuring the overall volume of the device. The multiple sets of guide wheels cooperate with each other to prevent deviation when the rolling steel is fed into the equipment.

[0028] The support cylinder 1 has a through-hole adjusting sleeve 11, and the adjusting cylinder 2 has a through-hole driving sleeve 21. The adjusting sleeve 11 is perpendicular to the steel rolling conveying path, and the driving sleeve 21 is inclined to the adjusting sleeve 11. The end of the shaft 5 slides in both the adjusting sleeve 11 and the driving sleeve 21. In this embodiment, after the adjusting cylinder 2 moves, the shaft 5 can be easily pushed on the adjusting sleeve 11 by the inclination of the driving sleeve 21. In order to reduce the friction between the shaft 5 and the adjusting sleeve 11 and the driving sleeve 21, lubricating oil can be applied to the contact part.

[0029] The adjusting cylinder 2 has a fixed threaded sleeve 22 in the middle of both sides, and the supporting cylinder 1 has a rotating screw 6 on both sides through a bracket. The threaded sleeve 22 is threadedly connected to the screw 6. The adjusting cylinder 2 slides outside the supporting cylinder 1 through the thread of the screw 6 and the threaded sleeve 22. In this embodiment, one end of the screw 6 is fixedly provided with a connecting part that cooperates with the tightening tool. The connecting part can be an inner or outer hexagon, a tightening wheel, etc., and can also be driven by a motor.

[0030] The upper end of the adjusting cylinder 2 is fixedly provided with a pressing platform 23, and a pressing bolt 7 is threadedly connected to the pressing platform 23. The bottom of the pressing bolt 7 faces the outer surface of the support cylinder 1. The pressing bolt 7 is pressed against the outside of the support cylinder 1 by the pressing platform 23. In this embodiment, multiple pressing bolts 7 can be provided. At the same time, a spring or other elastic element that abuts against the pressing platform 23 can be sleeved on the outside of the pressing bolt 7 to increase the axial friction between the pressing bolt 7 and the threaded part of the pressing platform 23, thereby ensuring the stability of the pressing of the bottom of the pressing bolt 7 against the support cylinder 1. Similarly, the corresponding surface of the support cylinder 1 can also be added with material or coating to increase the friction with the bottom of the pressing bolt 7.

[0031] The support cylinder 1 has a tapered inlet guide plate 12 on one side and a tapered outlet guide plate 13 on the other side. The tapered directions of the inlet guide plate 12 and the outlet guide plate 13 are the same. In this embodiment, the large opening of the tapered shape faces the feeding direction, which facilitates the introduction and export of rolled steel in the support cylinder 1.

[0032] In this embodiment, the support cylinder 1 has mounting bases 8 fixed at both ends of the bottom. The mounting bases 8 have mounting holes. In this embodiment, the upper end of the mounting base 8 can also fix a support block to support the bottom of the adjustment cylinder 2. The support block slides in contact with the bottom of the adjustment cylinder 2 to improve the structural stability of the support cylinder 1 and the adjustment cylinder 2. It should be noted that the support block should not affect the movement of the drive sleeve 21.

[0033] Understandably, this invention uses four sets of spaced-apart guides arranged in a cross shape. Each pair of sets corrects the rolling mill in the same direction. The spaced guide wheels in the same direction expand the correction range while maintaining a compact size. The coordinated work of multiple guide wheels effectively prevents deviation when the rolling mill is fed into the equipment. Furthermore, the shaft is placed within an adjusting sleeve and a driving sleeve. The sliding of the adjusting cylinder outside the support cylinder allows for synchronous adjustment of all guide wheel positions, resulting in simple operation, high precision, and avoidance of significant errors.

[0034] A specific application of this embodiment is as follows: When changing the size of the cylindrical rolling mill, it is necessary to adjust the position between multiple sets of guide rollers to ensure that the guide rollers are just right for the rolling mill to pass through, thereby ensuring the correction and anti-deviation effect. Loosen the clamping bolt 7, pass the rolling mill through the support cylinder 1, and rotate the screw 6 to drive the adjusting cylinder 2 to move outside the support cylinder 1 through the screw of the threaded sleeve 22. During the movement of the adjusting cylinder 2, the shaft 5 will slide in the adjusting sleeve 11 and the driving sleeve 21, thereby changing the distance between the two symmetrically arranged guide rollers. The adjusting cylinder 2 can link all the guide rollers to move synchronously until the guide rollers are completely in contact with the rolling mill. Stop the rotation of the screw 6 and screw the clamping bolt 7 to the outside of the support cylinder 1, so that the position between the support cylinder 1 and the adjusting cylinder 2 is fixed, thereby positioning the adjusted guide rollers.

[0035] When in use, the device is fixed to the equipment via the mounting base 8. The rolled steel enters the support cylinder 1 through the inlet guide plate 12, and then the rolled steel is corrected by four sets of spaced guide wheels to prevent the rolled steel from deviating when entering the equipment. Then the rolled steel is conveyed outward from the outlet guide plate 13.
