Description

Technical Field

[0001] This utility model belongs to the field of hot-rolled guide technology, and in particular relates to a guide assembly with adjustable curvature. Background Technology

[0002] Guides are crucial components in steel rolling production, used to guide and protect the workpiece as it correctly enters and exits the roll passes. They are typically installed on stands before and after the rolls, as well as between the mills. Like a precise "guide" and a loyal "guardian," they play an indispensable role in the rolling process.

[0003] Currently, most existing guide assemblies adopt a fixed structure, and the curvature of the guide wheel or guide plate cannot be adjusted. They can only be adapted to a single specification of rolled product. When it is necessary to roll products with different curvatures, the guide device needs to be replaced frequently, resulting in reduced production efficiency and increased costs.

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

[0005] The purpose of this invention is to provide a curved 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 relates to an adjustable curvature guide assembly, comprising a base and two curved guide rollers symmetrically arranged above the base. Mounting plates are movably mounted on the upper and lower ends of the curved guide rollers. Two mounting brackets are symmetrically arranged above the base, with their upper and lower ends fixedly connected by a fixing plate. A fixing shaft is fixedly mounted on the side of the fixing plate, rotatably connected to a rotating ring. The side of the rotating ring is fixedly connected to the mounting plate via a connecting rod. Rotation of the rotating ring drives the two curved guide rollers to rotate via the connecting rod and mounting plate. A translational guide roller is rotatably connected to a mounting bracket two located between the curved guide rollers and the fixed guide rollers. The fixed guide roller is rotatably connected to the mounting bracket one. The translational guide roller guides the steel profile passing between the fixed guide rollers into the space between the curved guide rollers.

[0008] Furthermore, the outer wall of the upper rotating ring is provided with gear teeth that mesh with the drive gear, and the drive gear is fixedly connected to the output end of the motor.

[0009] Furthermore, a sliding column is fixedly provided at the bottom end of the mounting plate below, and the sliding column is slidably connected to the arc-shaped groove opened on the top surface of the base.

[0010] Furthermore, a fixed seat is fixedly provided on the top surface of the base, and an electric push rod with an output end fixedly connected to the mounting frame is installed on the top of the fixed seat.

[0011] Furthermore, the mounting bracket is fixedly connected to the connecting seat above the top surface of the base.

[0012] Furthermore, the top surface of the base is provided with a T-shaped groove, and a slider is slidably disposed in the T-shaped groove. The top of the slider is provided with a connecting block that is fixedly connected to the bottom end of the mounting bracket.

[0013] Furthermore, the motor is mounted at the bottom end of the top plate of the fixed frame, and the fixed frame is fixedly connected to the top surface of the upper fixed plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a rotating ring to drive the connecting rod and mounting plate to rotate, which in turn drives the bending guide roller to rotate, creating an angle between the channel between the fixed guide rollers and the channel between the bending guide rollers, thereby adjusting the curvature of the steel profile.

[0016] This invention uses an electric push rod to drive the translational guide roller to move horizontally, thereby sealing the gap between the bending guide roller and the fixed guide roller after the bending guide roller rotates. It also acts as a transition for the steel section when it is bent, preventing the steel section from failing to accurately enter the space between the bending guide rollers.

[0017] 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

[0026] 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.

[0027] 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.

[0028] Please see Figures 1-5 As shown, this utility model is an adjustable curvature guide assembly, including a base 1 and two curved guide rollers 6 symmetrically arranged above the base 1. Mounting plates 7 are movably mounted at the upper and lower ends of the curved guide rollers 6. Two mounting brackets 301 are symmetrically arranged above the base 1, and the upper and lower ends of the two mounting brackets 301 are fixedly connected by a fixing plate 4. The fixing plate 4 has a fixed shaft fixed to its side away from each other, which is rotatably connected to a rotating ring 5. The side of the rotating ring 5 is fixedly connected to the mounting plate 7 via a connecting rod 501. The rotation of the rotating ring 5 drives the two curved guide rollers 6 to rotate via the connecting rod 501 and the mounting plate 7. A translational guide roller 8 is rotatably connected to a mounting bracket 801 arranged between the curved guide rollers 6 and the fixed guide rollers 3. The fixed guide roller 3 is rotatably connected to the mounting bracket 301. The translational guide roller 8 guides the steel profile passing between the fixed guide rollers 3 into the space between the curved guide rollers 6.

[0029] This embodiment provides a curvature-adjustable guide assembly. The steel profile enters between the translational guide rollers 8 through the fixed guide rollers 3. The rotating ring 5 drives the connecting rod 501 to rotate, thereby driving the mounting plate 7 and the bending guide roller 6 to bend. This causes the channel between the bending guide rollers 6 to form an angle with the channel between the translational guide rollers 8, causing the steel profile to bend. The rotating ring 5 rotates the bending guide roller 6 to different positions to achieve curvature adjustment. When the rotating ring 5 drives the bending guide roller 6 to rotate, the gap between one of the bending guide rollers 6 and the fixed guide roller 3 will increase. The translational guide roller 8 is set between the bending guide roller 6 and the fixed guide roller 3. The translational guide roller 8 can move laterally, which can not only play a transition role for the steel profile and prevent the angle between the channel between the bending guide rollers 6 and the channel between the translational guide roller 8 from being too large, thus preventing the steel profile from not being able to enter, but also block the gap to a certain extent to prevent the gap from becoming too large.

[0030] The upper rotating ring 5 has teeth 10 on its outer wall that mesh with the drive gear 11. The drive gear 11 is fixedly connected to the output end of the motor 12. The motor 12 drives the drive gear 11 to rotate, thereby driving the rotating ring 5 to rotate through the teeth 10.

[0031] The mounting plate 7 below is fixedly provided with a sliding column 701 at its bottom end, and the sliding column 701 is slidably connected to the arc-shaped sliding groove 102 opened on the top surface of the base 1. The cooperation between the sliding column 701 and the arc-shaped sliding groove 102 can ensure the stable rotation of the mounting plate 7.

[0032] The base 1 has a fixed seat 103 fixed on its top surface, and the fixed seat 103 has an electric push rod 9 with its output end fixed to the mounting frame 801. The electric push rod 9 drives the mounting frame 801 to move laterally, thereby driving the translation guide roller 8 to move and adjusting the position of the translation guide roller 8 so that the translation guide roller 8 can play a transition role.

[0033] The mounting bracket 301 is fixedly connected to the connecting seat 2 above the top surface of the base 1.

[0034] The base 1 has a T-shaped groove 101 on its top surface, and a slider 13 is slidably disposed in the T-shaped groove 101. The top of the slider 13 is provided with a connecting block 1301, which is fixedly connected to the bottom of the mounting frame 801. The stability of the mounting frame 801 when it moves is improved by the T-shaped groove 101, the slider 13 and the connecting block 1301.

[0035] The motor 12 is installed at the bottom of the top plate of the fixing frame 1201, and the fixing frame 1201 is fixedly connected to the top surface of the upper fixing plate 4.

[0036] It is understandable that this utility model can adjust the curvature of the steel profile to roll out workpieces with different degrees of bending, and then guide the steel profile through a transition to ensure that the steel profile accurately enters the bending guide roller 6.

[0037] A specific application of the operation process in this embodiment is as follows: The steel profile is fed from the side of the fixed guide roller 3 away from the bending guide roller 6 into the space between the fixed guide rollers 3. The steel profile enters the bending guide roller 6 through the fixed guide roller 3 and the translation guide roller 8. Then, the drive motor 12 drives the drive gear 11 to rotate, thereby driving the rotating ring 5 to rotate through the gear teeth 10, which in turn drives the mounting plate 7 and the bending guide roller 6 to rotate, causing the steel profile to bend. By controlling the rotation speed of the rotating ring 5, steel profiles with different curvatures can be processed. The electric push rod 9 can drive the translation guide roller 8 to move laterally to guide the steel profile through transition.
