Description

Technical Field

[0001] This utility model belongs to the technical field of steel rolling equipment structure, and in particular relates to a centering device for a billet rolling mill. Background Technology

[0002] With the rapid development of industries such as machinery and automobiles, the market demand for high-value-added products such as advanced cold heading steel, gear steel, alloy spring steel, and tool and die steel is increasing. The billet rolling mill is a key piece of equipment for the production of high-value-added steel products such as special steel bars and wire rods, and hot-rolled H-beams.

[0003] The centering and turning devices are located before and after the roughing mill. According to the rolling process requirements, the turning device can flip the rolled piece 90°, and the centering device can move the rolled piece laterally. The centering device is used to move the rolled piece laterally to ensure that it is aligned with the roll passes during the reciprocating rolling of the roughing mill, thus guiding the rolled piece. Therefore, the centering and turning devices are crucial components of the roughing mill.

[0004] In existing technologies, the centering devices of billet rolling mills, lacking a buffering function, make hard contact with the rolled piece during clamping, easily damaging the surface of the rolled piece and affecting its quality and subsequent processing. Therefore, there is an urgent need to research a centering device that can effectively reduce surface damage to the rolled piece during clamping. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a centering device for a billet rolling mill, which solves the technical problem that the centering device of the prior art is prone to causing damage to the surface of the rolled piece during the clamping process.

[0006] To achieve the above and other related objectives, this utility model provides a centering device for a roughing mill, used for transversely moving the rolled piece, comprising:

[0007] Support frame;

[0008] A conveyor roller mechanism, mounted on the support frame, is used to convey rolled products;

[0009] A transverse pusher mechanism is movably mounted on the support frame and is used to push and clamp the workpiece centering roller hole on the conveyor roller mechanism;

[0010] The transverse pusher mechanism includes a pair of pushers spaced apart on opposite sides of the conveyor roller mechanism, a plurality of swing links hinged at one end to the support frame for supporting the pair of pushers, and a drive member disposed on the support frame for driving the pair of pushers to move closer to or separate from each other.

[0011] Optionally, the number of swing links is eight, and each swing link is distributed at each corner of a pair of push plates.

[0012] Optionally, the width of the end of the swing link that is hinged to the support frame is greater than the width of the end of the swing link that is hinged to the push plate.

[0013] Optionally, the push plate is provided with a pair of vertical plates extending downward toward the direction of the swing link, and the swing link is inserted between the pair of vertical plates and hinged to the pair of vertical plates through a hinge shaft.

[0014] Optionally, the driving component includes a first hydraulic cylinder and a second hydraulic cylinder respectively disposed on the support frame and located below the push plate, wherein the first hydraulic cylinder and the second hydraulic cylinder respectively drive a pair of push plates to move closer to or separate from each other.

[0015] Optionally, it includes a plurality of rollers for moving the workpiece, a plurality of rotating shafts disposed on the support frame for supporting each of the rollers, and a plurality of drive motors disposed on the support frame for driving each of the rotating shafts to rotate, wherein each of the drive motors is connected to each of the rotating shafts via a coupling.

[0016] As described above, the centering device for a billet rolling mill of this utility model has at least the following beneficial effects:

[0017] The centering device of this billet rolling mill is equipped with a conveyor roller mechanism to transfer the rolled piece to the next process for processing. By setting up a transverse pusher mechanism, which is connected to the support frame by one end of multiple swinging links, a pair of pushers can be driven by a drive component to move closer or separate from each other under the swinging of the swinging links. This achieves centering adjustment of the rolled piece on the one hand, and clamping or releasing the rolled piece on the other hand. Furthermore, the swinging of the swinging links effectively avoids hard contact with the rolled piece, reducing damage to the surface of the rolled piece. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0027] Please see Figure 1 This utility model provides a centering device for a billet rolling mill, including a support frame 1, a conveyor roller mechanism 2, and a transverse pusher mechanism 3. The conveyor roller mechanism 2 is mounted on the support frame 1 and can convey the rolled piece to the next process for processing. The transverse pusher mechanism 3 is movably mounted on the support frame 1 and can be used to push and clamp the rolled piece on the conveyor roller mechanism 2 to center it in the roll hole. Specifically, the transverse pusher mechanism 3 includes a pair of pushers 31, a plurality of swing links 2, and a drive member 33. The pair of pushers 31 are spaced apart on opposite sides of the conveyor roller mechanism 2. One end of the swing link 32 is hinged to the support frame 1 and is used to support the pair of pushers 31. The drive member 33 is mounted on the support frame 1 and can be used to drive the pair of pushers to move closer or separate from each other.

[0028] In the application, when the rolled piece is conveyed to the centering device, the drive unit 33 is activated, and the swinging linkage 32 swings to drive a pair of push plates 31 closer to the rolled piece until it is clamped. At this time, the drive unit 33 continues to work, driving the pair of push plates 31 to move laterally, thereby pushing the rolled piece to the centering roll hole. During the clamping and pushing process, due to the swinging action of the swinging linkage 32, a certain buffer is formed between the push plates 31 and the rolled piece, avoiding hard contact and effectively reducing damage to the surface of the rolled piece.

[0029] Preferably, there are eight swing links 32, each distributed at one of the corners of the push plates 31. This ensures better stability and uniformity of the push plates 31 when clamping the rolled piece, preventing displacement or deformation during clamping. Furthermore, the number and distribution of the swing links 32 can be adjusted according to the size and shape of the rolled piece to meet the centering requirements of rolled pieces of different specifications.

[0030] Further, please refer to Figure 1 As shown, the width of the end of the swing link 32 that is hinged to the support frame 1 is greater than the width of the end of the swing link 32 that is hinged to the push plate 31. This design allows the swing link 32 to better adapt to the movement trajectory of the push plate 31 during swinging, reducing friction and resistance, and improving the working efficiency and stability of the centering device.

[0031] Further, please refer to Figure 1 and Figure 2 As shown, a pair of vertical plates 34 extend downwards from the push plate 31 toward the swing link 32. The swing link 32 is inserted between the pair of vertical plates 34 and is hinged to the pair of vertical plates 34 via a hinge shaft. This hinged connection between the vertical plates 34 and the hinge shaft ensures a more stable connection between the swing link 32 and the push plate 31, while also facilitating the installation and removal of the swing link 32 on the push plate 31. When the swing link 32 swings, the vertical plates 34 provide stable support for it, preventing it from wobbling or falling off, thereby further improving the stability and reliability of the centering device.

[0032] Further, please refer to Figure 1As shown, the driving component 33 includes a first hydraulic cylinder 331 and a second hydraulic cylinder 332. The first hydraulic cylinder 331 and the second hydraulic cylinder 332 are respectively mounted on the support frame 1 and located below the push plate 31. The first hydraulic cylinder 331 and the second hydraulic cylinder 332 respectively drive a pair of push plates 31 to move closer to or separate from each other. In this way, through the coordinated action of the two hydraulic cylinders, the moving speed and distance of the push plates can be controlled more precisely, thereby achieving the centering adjustment of the rolled piece. The location of the first hydraulic cylinder 331 and the second hydraulic cylinder 332 below the push plate 31 makes the overall structure more compact, saving space and facilitating installation and use on the rolling mill. At the same time, the reasonable placement of the first hydraulic cylinder 331 and the second hydraulic cylinder 332 avoids interference with the rolled piece or other components, ensuring the normal operation of the centering device.

[0033] Further, please refer to Figure 1 As shown, the transverse pusher mechanism 2 comprises multiple rollers 21, multiple rotating shafts 22, and multiple drive motors 23. Each rotating shaft 22 is mounted on a support frame 1 and supports the roller 21. The drive motor 23 is mounted on the support frame 1 and drives the rotating shafts 22 to rotate. Specifically, each drive motor 23 is connected to the rotating shaft 22 via a coupling 24. Thus, when the workpiece is clamped and centered, the drive motor 23 can be started to rotate the rotating shaft 22, which in turn drives the rollers 21 to rotate, thereby propelling the workpiece to the next process. Furthermore, by designing the rollers 21, the frictional resistance between the workpiece and the conveying mechanism can be reduced, minimizing damage to the workpiece surface and improving conveying efficiency.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
