Description

Technical Field

[0001] This utility model belongs to the technical field of steel rolling equipment structure, and in particular relates to a shaft support for a reciprocating transverse rolling mill. Background Technology

[0002] A billet rolling mill is a piece of equipment used in the steel production process to roll raw materials (such as steel ingots and continuously cast billets) into billets that meet the requirements of subsequent processing. It is a core piece of equipment in the metallurgical rolling process. The reciprocating transverse billet rolling mill is a special type of billet rolling mill with a core feature that the rolls can also reciprocate laterally (perpendicular to the billet conveying direction) while rotating. This causes the billet to undergo multi-directional compression and deformation during the rolling process, thereby improving the problem of uneven deformation at the edge of the billet in traditional rolling mills. It is especially suitable for billet rolling of large cross-sections or complex shapes.

[0003] The drive shaft is a key component in the billet rolling mill used to transmit power. One end of it is connected to a motor or reducer through a coupling or other device; the other end is connected to the roll through a flat head sleeve, transmitting power to the roll and driving it to rotate for rolling. When the flat head sleeve of the drive shaft and the flat head on the roll are misaligned, detached, or have poor contact, it will cause the power transmission to be interrupted or unstable. This phenomenon is called the flat head sleeve overlap phenomenon.

[0004] Because the rolls of a reciprocating transverse rolling mill also reciprocate laterally while rotating, and the existing shaft support brackets are generally fixedly arranged on the drive side of the rolling mill near the flat end sleeve of the rolls, the existing shaft support brackets cannot be adjusted according to the timely position of the drive shaft, and therefore cannot achieve the function of stably supporting the drive shaft. At the same time, the phenomenon of the flat end sleeve overlapping is also prone to occur. 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 shaft support bracket for a reciprocating transverse billet rolling mill, which solves the problem that when the rolls of the reciprocating transverse billet rolling mill are rotating and also reciprocating laterally, the existing shaft support bracket cannot be adjusted according to the timely position of the transmission shaft, thus failing to achieve the function of stably supporting the transmission shaft, and is also prone to the problem of flat head overlap.

[0006] To achieve the above and other related objectives, this utility model provides a shaft support bracket for a reciprocating transverse rolling mill, installed on the drive side, comprising:

[0007] The bracket component is arranged along the longitudinal direction; during rolling, the bracket component and the drive shaft are disengaged; during roll changing or maintenance, the bracket component supports multiple drive shafts arranged along the longitudinal direction.

[0008] The lateral movement component drives the billet mill to move in the lateral direction and is used to move the billet mill to the roll change / maintenance station during roll change or maintenance.

[0009] The lifting component drives the bracket component to move in the longitudinal direction and is used to support the transmission shaft when changing rollers or performing maintenance.

[0010] Optionally, during rolling, the lateral movement component drives the billet mill to move out of the roll changing / maintenance station in the lateral direction, and the lifting component drives the bracket component to move in the longitudinal direction until it is disengaged from the transmission shaft.

[0011] Optionally, the lifting component includes a frame, a lifting platform, a hydraulic motor, and an encoder; the bracket component is slidably mounted on the frame along the longitudinal direction, and the telescopic end of the lifting platform is connected to the bracket component; the hydraulic motor drives the telescopic end of the lifting platform to extend or retract; the encoder controls the movement of the hydraulic motor.

[0012] Optionally, the bracket component includes an upper bracket and a lower bracket, which are fixedly connected longitudinally by a slide bar; a slide groove is provided on the side of the upright, and the slide bar is slidably installed in the slide groove; the telescopic end of the elevator is connected to the bottom of the lower bracket.

[0013] Optionally, the lateral movement component includes a hydraulic cylinder; the hydraulic cylinder drives the billet mill to move laterally; and a displacement sensor is installed on the hydraulic cylinder.

[0014] As described above, the shaft support bracket of the reciprocating transverse rolling mill of this utility model has at least the following beneficial effects:

[0015] This reciprocating lateral traverse billet mill features a shaft support bracket that holds multiple drive shafts arranged longitudinally. A lifting component drives the bracket components to move longitudinally, while a lateral traverse component drives the billet mill to move laterally. This design allows the lifting component to remain inactive at the start of rolling, disengaging the bracket components from the drive shafts. The lateral traverse component then moves the billet mill laterally according to the rolling process. During roll changes or maintenance, the lateral traverse component moves the billet mill to the roll change / maintenance station; the lifting component then drives the bracket components to support the drive shafts. After the roll change is completed... Alternatively, during maintenance, the lifting and lateral movement components work together again to disengage the support component from the transmission shaft. This ensures that the support bracket can be adjusted in a timely manner according to the position of the transmission shaft, thus ensuring that the transmission shaft is securely supported and the position of the flat head sleeve on the transmission shaft is fixed. Ultimately, this solves the problem that in existing technologies, when the rolls of a reciprocating lateral rolling mill are rotating and also reciprocating laterally, the support bracket cannot be adjusted according to the timely position of the transmission shaft, thus failing to securely support the transmission shaft and easily causing the flat head sleeve to overlap.

[0023] 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.

[0024] Please see Figures 1 to 5 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.

[0025] 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.

[0026] Please see Figure 1 and Figure 2 This utility model provides a shaft support bracket for a reciprocating transverse rolling mill. Like existing technology, it is installed on the drive side of the rolling mill, near the flat head sleeve of the drive shaft 4. The difference from existing technology is that this shaft support bracket includes:

[0027] like Figure 1 and Figure 2 The bracket component 1 shown is arranged in the longitudinal direction and is used to support multiple transmission shafts 4 arranged in the longitudinal direction. This is the basic function of the shaft bracket.

[0028] like Figure 1 and Figure 2 The lifting component 2 shown drives the bracket component 1 to move in the longitudinal direction.

[0029] like Figure 1 and Figure 2 The lateral movement component 3 shown drives the billet mill to move in the lateral direction.

[0030] The reciprocating transverse traverse billet mill features a shaft support bracket that supports multiple transmission shafts 4 arranged longitudinally. A lifting component 2 drives the bracket component 1 to move longitudinally, and a transverse component 3 drives the billet mill to move laterally. This design allows the lifting component 2 to remain inactive at the start of rolling, disengaging the bracket component 1 from the transmission shafts 4. The transverse component 3 then traverses the billet mill according to the rolling process. During roll changing or maintenance, the transverse component 3 traverses the billet mill to the roll changing / maintenance station; the lifting component 2 drives the bracket component 1 to support the transmission shafts 4. When the roll change or maintenance is completed, the lifting component 2 and the lateral movement component 3 work together again to drive the bracket component and the transmission shaft to disengage; thus ensuring that the bracket can be adjusted in time according to the position of the transmission shaft 4, thereby ensuring that the transmission shaft 4 is stably supported and the position of the flat head sleeve on the transmission shaft 4 is fixed; finally, it solves the problem that when the rolls of the reciprocating lateral rolling mill are rotating and also reciprocating laterally, the existing bracket cannot be adjusted according to the timely position of the transmission shaft 4, thus failing to stably support the transmission shaft 4, and is also prone to the problem of the flat head sleeve overlapping.

[0031] In another implementation, please refer to Figure 2 , Figure 3 and Figure 5 The lifting component 2 includes a frame 21, a lifting mechanism 22, a hydraulic motor 23, and an encoder 24. The bracket component 1 is slidably mounted on the frame 21 along the longitudinal direction, and the telescopic end of the lifting mechanism 22 is connected to the bracket component 1. The hydraulic motor 23 drives the telescopic end of the lifting mechanism 22 to extend or retract, thereby driving the bracket component 1 to slide along the longitudinal direction. At the same time, the encoder 24 controls the movement of the hydraulic motor 23. The encoder 24 is a sensor used to detect and provide feedback on the position, speed, or angle of mechanical movement. Its core function is to convert mechanical movement into electrical signals so that the control system can monitor and adjust the equipment status in real time. The specific working mode of the lifting mechanism 22 and the hydraulic motor 23 in this embodiment can be referred to Chinese Utility Model Patent No. CN202264047U.

[0032] In another implementation, please refer to Figure 2 and Figure 4 The bracket component 1 includes an upper bracket 11 and a lower bracket 12, which are fixedly connected longitudinally by a slide bar; the side of the upright 21 is provided with a slide groove, and the slide bar is slidably installed in the slide groove; the telescopic end of the elevator 22 is connected to the bottom of the lower bracket 12; this embodiment provides a specific structural form of the bracket component 1, and the design of the upper bracket 11 and the lower bracket 12 can support two transmission shafts 4 distributed in the longitudinal direction.

[0033] In other implementations, such as Figure 3 and Figure 4 As shown, the lateral movement component 3 includes a hydraulic cylinder 31; the hydraulic cylinder 31 drives the billet mill to move laterally; a displacement sensor is installed on the hydraulic cylinder 31, thereby realizing the precise movement of the bracket component 1 in the lateral direction.

[0034] In summary, this utility model, through its structural design of a bracket component 1 arranged longitudinally supporting multiple transmission shafts 4 arranged longitudinally, a lifting component 2 driving the bracket component 1 to move longitudinally, and a lateral movement component 3 driving the billet mill to move laterally, allows the lifting component 2 to initially not operate at the start of rolling, at which point the bracket component 1 and the transmission shafts 4 are out of contact, and the lateral movement component 3 moves the billet mill laterally according to the rolling process. During roll changing or maintenance, the lateral movement component 3 moves the billet mill laterally to the roll changing / maintenance station; the lifting component 2 drives the bracket component 1 to support the transmission shafts 4; and after roll changing / maintenance is completed... When the roller is being repaired or maintenance is completed, the lifting component 2 and the lateral movement component 3 work together again to drive the bracket component and the transmission shaft to disengage. This ensures that the bracket can be adjusted in a timely manner according to the position of the transmission shaft 4, thus ensuring that the transmission shaft 4 is securely supported and that the flat head sleeve on the transmission shaft 4 is fixed in position. Ultimately, this solves the problem that in existing technologies, when the rollers of a reciprocating lateral rolling mill are rotating and also reciprocating laterally, the bracket cannot adjust accordingly to the timely position of the transmission shaft 4, thus failing to securely support the transmission shaft 4 and easily causing the flat head sleeve to overlap. Therefore, this invention effectively overcomes the shortcomings of existing technologies and has high industrial application value.

[0035] 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.
