Description

Technical Field

[0001] This disclosure relates to the field of metallurgical steel rolling technology, and in particular to a flywheel assembly and a flying shear machine. Background Technology

[0002] In the metallurgical steel rolling industry, flying shears are commonly used for shearing rolled bars. Flying shears in related technologies are typically equipped with a flywheel. When shearing large-diameter bars, the flywheel is mounted on the main shaft and rotates synchronously with it, thereby increasing the rotational inertia of the main shaft and enhancing the shearing force. When shearing small-diameter bars, the flywheel is separated from the main shaft, thus reducing the operating load and energy consumption of the flying shear while still meeting shearing requirements.

[0003] However, due to the relatively large weight and volume of the flywheel, manual loading and unloading of the flywheel is difficult. It often requires the use of lifting equipment on the production site to assist in loading and unloading the flywheel. The operation is time-consuming and poses certain safety hazards, which is not conducive to the continuous and stable operation of production. Summary of the Invention

[0004] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] In view of the above, a flywheel assembly is provided according to a first aspect of the present disclosure, comprising: The bearing is installed, including an inner ring and an outer ring. The inner ring is used to fix the main shaft of the flying shear machine. The flywheel body is fixedly fitted onto the outer ring; A locking element is provided on the mounting bearing, and the locking element has a limited state and an unlocked state; In the limited position, the locking element is fixedly connected to the inner ring and the outer ring to restrict the relative rotation of the inner ring and the outer ring; in the unlocked position, the locking element is separated from at least one of the inner ring and the outer ring to allow the inner ring and the outer ring to rotate relative to each other.

[0006] In one feasible implementation, the inner ring has a first threaded hole in the radial direction, the outer ring has a second threaded hole in the radial direction, and the locking member includes a locking bolt. Both the first threaded hole and the second threaded hole are adapted to be threadedly engaged with the locking bolt. In the limited position, the locking bolt passes through the first threaded hole and the second threaded hole; In the unlocked state, the locking bolt is separated from the first threaded hole and / or the second threaded hole.

[0007] In one feasible implementation, the flywheel body has a mounting hole in the radial direction. The mounting hole is coaxially arranged with the second threaded hole. The mounting hole includes a first hole section and a second hole section. The second hole section is connected between the first hole section and the second threaded hole. The diameter of the first hole section is larger than the diameter of the head of the locking bolt. The diameter of the second hole section is smaller than the diameter of the first hole section but larger than the diameter of the shank of the locking bolt. When in the limit position, the head of the locking bolt is located within the first hole section.

[0008] In one feasible embodiment, the mounting bearing further includes rollers movably disposed between the inner and outer rings; along the axial direction of the mounting bearing, both the first threaded hole and the second threaded hole are spaced apart from the rollers.

[0009] In one feasible implementation, the flywheel assembly further includes: A baffle is installed on the flywheel body and is used to cover the gap between the inner and outer rings.

[0010] In one feasible implementation, a baffle is detachably disposed at one end of the flywheel body, the baffle having an annular structure and being arranged coaxially with the mounting bearing; The outer peripheral wall diameter of the baffle is larger than the outer peripheral wall diameter of the outer ring, and the inner peripheral wall diameter of the baffle is smaller than the outer peripheral wall diameter of the inner ring but larger than the inner peripheral wall diameter of the inner ring.

[0011] In one feasible implementation, the baffle is made of a light-transmitting material.

[0012] In one feasible implementation, the locking bolt has a performance grade of 10.9 or higher.

[0013] In one feasible implementation, the mounting bearing is a deep groove ball bearing or a cylindrical roller bearing.

[0014] A flying shear machine is provided according to a second aspect of the embodiments of this disclosure, comprising: Flywheel components as described in any of the first aspects above.

[0015] The above description is merely an overview of the technical solution provided in this disclosure.

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] like Figures 1 to 3 As shown, a flywheel assembly is provided according to a first aspect of the present disclosure, comprising: a mounting bearing 100 including an inner ring 110 and an outer ring 120, the inner ring 110 being fixedly sleeved on the main shaft 10 of a flying shear machine; a flywheel body 200 fixedly sleeved on the outer ring 120; and a locking member 300 disposed on the mounting bearing 100, the locking member 300 having a limited state and an unlocked state; wherein, in the limited state, the locking member 300 is fixedly connected to the inner ring 110 and the outer ring 120 to restrict relative rotation between the inner ring 110 and the outer ring 120; and in the unlocked state, the locking member 300 is separated from at least one of the inner ring 110 and the outer ring 120 to allow relative rotation between the inner ring 110 and the outer ring 120.

[0020] The flywheel assembly provided in this embodiment includes the aforementioned mounting bearing 100, flywheel body 200, and locking member 300. The mounting bearing 100 includes an inner ring 110 and an outer ring 120. The flywheel body 200 is fixedly sleeved on the outer ring 120. In practical applications, the inner ring 110 is fixedly sleeved on the main shaft 10 of the flying shear machine, so that when the main shaft 10 rotates, the inner ring 110 can rotate synchronously with the main shaft 10. The mounting bearing 100 provides structural support for the flywheel body 200 to ensure the stability and reliability of the flywheel body 200's installation on the main shaft 10. The locking member 300 is disposed on the mounting bearing 100 and has a limited state and an unlocked state; as shown... Figure 1 and Figure 3 As shown, in the aforementioned limited state, the inner ring 110 and the outer ring 120 are fixed by the locking member 300, which can prevent the inner ring 110 and the outer ring 120 from rotating relative to each other. Therefore, when the main shaft 10 rotates, the flywheel body 200 can rotate synchronously with the main shaft 10, which can increase the rotational inertia of the main shaft 10, facilitating the flying shear machine to output a larger shearing force and perform larger-diameter bar shearing; for example... Figure 2 As shown, in the aforementioned unlocked state, the locking member 300 is separated from at least one of the inner ring 110 and the outer ring 120, allowing the inner ring 110 and the outer ring 120 to rotate relative to each other. This prevents the inner ring 110 from driving the outer ring 120 and the flywheel body 200 to rotate when the main shaft 10 rotates, reducing the rotational inertia and resistance of the main shaft 10. This facilitates the shearing of smaller-sized bars and reduces the operating load and energy consumption of the flying shear. Based on this, in practical applications, the flywheel assembly provided in this embodiment can change the rotational inertia of the main shaft 10 and the output shearing force of the flying shear by switching the state of the locking member 300, without requiring overall movement of the flywheel assembly. This reduces the demand for lifting equipment and safety hazards associated with flywheel loading and unloading operations, shortens the time required for these operations, and helps ensure the continuity and safety of steel rolling production.

[0021] It should be noted that, in order to facilitate understanding of how the flywheel assembly provided in this disclosure is used, Figures 1 to 3 The main shaft 10 of the flying shear is schematically shown in the figure.

[0022] It is understandable that, in practical applications, the aforementioned locking member 300 being separated from at least one of the inner ring 110 and the outer ring 120 can be either the locking member 300 being separated from the inner ring 110 and fixedly connected to the outer ring 120, or the locking member 300 being separated from the outer ring 120 and fixedly connected to the inner ring 110, or the locking member 300 being separated from both the inner ring 110 and the outer ring 120, so that the inner ring 110 and the outer ring 120 are not fixedly connected by the locking member 300.

[0023] Understandably, in practical applications, when it is necessary to switch the state of the locking element 300, the flying shear machine can be turned off first to stop the aforementioned main shaft 10 from rotating, so as to ensure the safe and stable operation of the locking element 300.

[0024] It is understood that the aforementioned mounting bearing 100 may also include a roller 130 movably disposed between the inner ring 110 and the outer ring 120, so as to reduce the resistance when the inner ring 110 and the outer ring 120 rotate relative to each other when the locking member 300 is in the aforementioned unlocked state; correspondingly, when the locking member 300 is in the aforementioned unlocked state, since the flywheel body 200 has a large inertia, it is not easy for the main shaft 10 to drive the flywheel body 200 to rotate through the mounting bearing 100 when starting operation.

[0025] like Figures 1 to 3 As shown, in one feasible embodiment, the inner ring 110 has a first threaded hole 1101 radially, and the outer ring 120 has a second threaded hole 1201 radially. The locking member 300 includes a locking bolt 310. Both the first threaded hole 1101 and the second threaded hole 1201 are adapted to be threadedly engaged with the locking bolt 310. In the limited state, the locking bolt 310 passes through the first threaded hole 1101 and the second threaded hole 1201. In the unlocked state, the locking bolt 310 is separated from the first threaded hole 1101 and / or the second threaded hole 1201.

[0026] In this technical solution, the inner ring 110 and the outer ring 120 may respectively have the aforementioned first threaded hole 1101 and the aforementioned second threaded hole 1201, and the locking member 300 may include the aforementioned locking bolt 310. Based on the aforementioned configuration, the locking member 300 can be switched by screwing the locking bolt 310 into the first threaded hole 1101 and the second threaded hole 1201, or by screwing the locking bolt 310 out of at least one of the first threaded hole 1101 and the second threaded hole 1201. This makes the operation of the locking member 300 more convenient and efficient, which is beneficial to improving the ease of use of the flywheel assembly. Furthermore, the structure and installation method of the locking member 300 are relatively simple, which can reduce the processing and use costs of the flywheel assembly.

[0027] It is understandable that the first threaded hole 1101 and the second threaded hole 1201 are aligned in the axial direction of the bearing 100. When it is necessary to switch the locking member 300 from the unlocked state to the limited state, the first threaded hole 1101 and the second threaded hole 1201 can be arranged coaxially by rotating the main shaft 10 or the flywheel body 200, so as to facilitate the insertion of the locking bolt 310.

[0028] It is understandable that, in practical applications, the aforementioned locking bolt 310 being separated from the first threaded hole 1101 and / or the second threaded hole 1201 can be either separated from the first threaded hole 1101 and passing through the second threaded hole 1201, or separated from the second threaded hole 1201 and passing through the first threaded hole 1101, or simultaneously separated from both the first threaded hole 1101 and the second threaded hole 1201, so that the inner ring 110 and the outer ring 120 are not fixedly connected by the locking bolt 310.

[0029] It is understood that the number of first threaded holes 1101 and second threaded holes 1201 is the same and can both be multiple. Multiple first threaded holes 1101 can be arranged in an array along the axial and circumferential directions of the inner ring 110, and multiple second threaded holes 1201 can be arranged in an array along the axial and circumferential directions of the outer ring 120. Each first threaded hole 1101 corresponds to one second threaded hole 1201. Correspondingly, the number of locking bolts 310 can also be multiple, and the number of locking bolts 310 is the same as the number of first threaded holes 1101 and second threaded holes 1201. Each locking bolt 310 corresponds to a set of first threaded holes 1101 and second threaded holes 1201. Thus, in the aforementioned limited position, the inner ring 110 can transmit torque to the outer ring 120 and the flywheel body 200 through multiple locking bolts 310, which is beneficial for the flywheel body 200 to stably and reliably follow the rotation of the main shaft 10.

[0030] For example, the first threaded hole 1101 can be a blind hole, and the open end of the first threaded hole 1101 is located on the outer peripheral wall of the inner ring 110, thereby ensuring the quality of the inner peripheral wall of the inner ring 110, which is beneficial for the bearing 100 to be installed and reliably connected to the spindle 10.

[0031] like Figures 1 to 3 As shown, in one feasible embodiment, the flywheel body 200 has a mounting hole 201 radially arranged. The mounting hole 201 is coaxially arranged with the second threaded hole 1201. The mounting hole 201 includes a first hole section 201a and a second hole section 201b. The second hole section 201b connects the first hole section 201a and the second threaded hole 1201. The diameter of the first hole section 201a is larger than the diameter of the head of the locking bolt 310. The diameter of the second hole section 201b is smaller than the diameter of the first hole section 201a but larger than the diameter of the shank of the locking bolt 310. In the limited state, the head of the locking bolt 310 is located in the first hole section 201a.

[0032] In this technical solution, the flywheel body 200 may have the aforementioned mounting hole 201. In the limited position, the head of the locking bolt 310 is located within the aforementioned first hole segment 201a of the mounting hole 201. Based on the aforementioned configuration, in the aforementioned limited position, the head of the locking bolt 310 can be hidden within the first hole segment 201a of the mounting hole 201, thereby preventing the locking bolt 310 from protruding radially outward from the flywheel body 200. This reduces the risk of interference and collision between the locking bolt 310 and the external structure, which is beneficial to ensuring the stable and safe operation of the flywheel body 200. Furthermore, since the diameter of the first hole segment 201a is larger than the diameter of the head of the locking bolt 310, it provides a wrench, socket, or other tools for disassembling and assembling the locking bolt 310. The installation provides operating space, facilitating quick switching of the locking member 300's state. Compared to the first hole section 201a, the second hole section 201b of the aforementioned mounting hole 201 has a smaller diameter, and the diameter of the second hole section 201b is larger than the diameter of the shank of the locking bolt 310. Therefore, when inserting the locking bolt 310, the mounting hole 201 can use the second hole section 201b to limit and guide the locking bolt 310, making it easier for the locking bolt 310 to be quickly screwed into the second threaded hole 1201, thus improving the operational convenience of the locking member 300.

[0033] It is understood that the locking bolt 310 may include a head and a shank, one end of which is connected to the head and the shank is provided with external threads, and the head is used to cooperate with bolt removal and installation tools such as wrenches and sockets.

[0034] It is understandable that when there are multiple second threaded holes 1201, the number of mounting holes 201 can be the same as the number of second threaded holes 1201, and the mounting holes 201 and the second threaded holes 1201 are arranged coaxially in a one-to-one correspondence.

[0035] For example, such as Figure 2 As shown, in the unlocked state, the locking bolt 310 is separated from the first threaded hole 1101, the shank of the locking bolt 310 is located in the second threaded hole 1201 at the end away from the head, and the head of the locking bolt 310 protrudes from the side of the first hole section 201a away from the second hole section 201b. Based on this, on the one hand, in the unlocked state, the outer ring 120 can fix the locking bolt 310 through the second threaded hole 1201, which can reduce the risk of the locking bolt 310 being lost; on the other hand, when switching the state of the locking member 300, the amount of rotation operation of the locking bolt 310 can be reduced, which is conducive to achieving rapid switching of the state of the locking member 300; furthermore, in the unlocked state, the head of the locking bolt 310 protrudes from the radially outer side of the flywheel body 200, which makes it easy to contact the external structure to hinder the rotation of the flywheel body 200, which is conducive to ensuring the positional stability of the flywheel assembly.

[0036] For example, when the flying shear machine includes a flywheel cover, the inner wall of the flywheel cover may be provided with a limiting member for engaging with the head of the locking bolt 310, so that in the unlocked state, the aforementioned limiting member can be used to restrict the rotation of the locking bolt 310 and the flywheel body 200 around the axis of the main shaft 10.

[0037] like Figures 1 to 3 As shown, in one feasible embodiment, the mounting bearing 100 further includes a roller 130 movably disposed between the inner ring 110 and the outer ring 120; along the axial direction of the mounting bearing 100, the first threaded hole 1101 and the second threaded hole 1201 are both arranged at intervals from the roller 130.

[0038] In this technical solution, a first threaded hole 1101 and a second threaded hole 1201 can be provided along the axial direction of the bearing 100, both spaced apart from the roller 130. Based on the aforementioned arrangement, the first threaded hole 1101 and the second threaded hole 1201 can avoid the raceway of the roller 130 and reduce the risk of the roller 130 contacting the locking bolt 310. This facilitates the stable and smooth movement of the roller 130 between the outer ring 120 and the inner ring 110, and ensures the stable and reliable operation of the spindle 10 when the locking member 300 is in the aforementioned unlocked state.

[0039] like Figure 3 As shown, in one feasible embodiment, the flywheel assembly further includes a baffle 400 disposed on the flywheel body 200, the baffle 400 being used to block the gap 101 between the inner ring 110 and the outer ring 120.

[0040] In this technical solution, the flywheel assembly may further include the aforementioned baffle 400. Based on the aforementioned configuration, the flywheel assembly can utilize the baffle 400 to shield the radial gap 101 between the inner ring 110 and the outer ring 120, thereby reducing the probability of impurities such as iron filings and dust entering the aforementioned gap 101, reducing the risk of jamming or structural damage to the mounting bearing 100 and locking component 300, which is beneficial for extending the service life of the mounting bearing 100 and locking component 300, and reducing the maintenance costs of the mounting bearing 100 and locking component 300.

[0041] like Figure 3 As shown, in one feasible embodiment, the baffle 400 is detachably disposed at one end of the flywheel body 200. The baffle 400 has an annular structure and is coaxially arranged with the mounting bearing 100. The outer peripheral wall diameter of the baffle 400 is larger than the outer peripheral wall diameter of the outer ring 120, and the inner peripheral wall diameter of the baffle 400 is smaller than the outer peripheral wall diameter of the inner ring 110 but larger than the inner peripheral wall diameter of the inner ring 110.

[0042] In this technical solution, the setting position and structural parameters of the baffle 400 are constrained. Based on the aforementioned settings, on the one hand, it is convenient to increase the exposure of the mounting bearing 100 by disassembling the baffle 400, which facilitates the inspection and maintenance of the mounting bearing 100; on the other hand, the baffle 400 can block the aforementioned gap 101 along the circumference of the mounting bearing 100 and can prevent the baffle 400 from contacting the main shaft 10, ensuring the stable and reliable operation of the main shaft 10 when the locking member 300 is in the aforementioned unlocked state; furthermore, it can reduce the influence of the baffle 400 on the dynamic balance of the flywheel body 200, which is beneficial to the stable and reliable rotation of the flywheel body 200 when the locking member 300 is in the aforementioned limited state.

[0043] It is understandable that there are multiple ways to detach the flywheel body 200 and the baffle 400. The specific method can be selected according to actual needs, and no further restrictions are imposed here.

[0044] It is understandable that there can be two baffles 400, and both ends of the flywheel body 200 can be provided with the aforementioned baffles 400.

[0045] In one possible implementation, the baffle 400 is made of a light-transmitting material.

[0046] In this technical solution, the baffle 400 can be made of a light-transmitting material. Based on the aforementioned configuration, operators can easily observe the condition of the installed bearing 100 through the baffle 400, thereby improving the ease of maintenance of the flywheel assembly.

[0047] It is understood that the aforementioned light-transmitting materials may be, but are not limited to, plexiglass or tempered glass.

[0048] In one feasible implementation, the locking bolt 310 has a performance grade of 10.9 or higher.

[0049] In this technical solution, the performance grade of the locking bolt 310 can be higher than or equal to grade 10.9, which can ensure the structural strength of the locking bolt 310, reduce the risk of structural bending and breakage of the locking bolt 310, and help extend the service life of the locking bolt 310. In addition, under the aforementioned limiting state, it is beneficial to transmit a larger torque between the inner ring 110 and the outer ring 120, which provides a guarantee for the flying shear machine to output a larger shearing force.

[0050] For example, the performance grade of the locking bolt 310 may be, but is not limited to, grade 10.9 or grade 12.9.

[0051] like Figures 1 to 3 As shown, in one feasible embodiment, the mounting bearing 100 is a deep groove ball bearing or a cylindrical roller bearing.

[0052] In this technical solution, the mounting bearing 100 is a deep groove ball bearing or a cylindrical roller bearing. Deep groove ball bearings and cylindrical roller bearings are suitable for withstanding large radial forces, which helps the mounting bearing 100 to stably and reliably support the flywheel body 200, thus ensuring the installation and operational stability of the flywheel body 200.

[0053] According to a second aspect of the present disclosure, a flying shear machine is provided, comprising: a flywheel assembly as described in any of the first aspects above.
