Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, in particular to a roller auxiliary turning device. Background Art

[0002] Conditioning is a key process in roll production, aimed at refining the roll's metallographic structure and increasing its service life. During conditioning, the rolls are placed horizontally in a heating furnace for high-temperature heating (approximately 900°C). The hot rolls are then moved to a conditioning tank for quenching.

[0003] Because most rolls on the market are relatively long, the height of most milling plants is insufficient to support their vertical height. Therefore, existing techniques typically heat the rolls horizontally, then use a crane and chains to lift them out of the heating furnace and flip them vertically in the quenching tank. However, due to their length and heavy weight, the rolls are prone to axial bending during the flipping process, resulting in uneven circumferential hardness and failing to meet the standard for the quenching process. Utility Model Content

[0004] The utility model provides a roller auxiliary turning device, which solves the problem in the related art that the roller is easily bent in the axial direction during the turning process.

[0007] A holding tank for holding quenching liquid;

[0008] The rotating frame is rotatably arranged relative to the containing tank, and is used to support the roller. After the rotating frame rotates, the roller is horizontal or vertical, and the center of gravity of the rotating frame is lower than the rotation axis of the rotating frame.

[0010] A baffle is provided on the rotating frame, the baffle is located on one side of the rotating axis of the rotating frame, and the baffle is used to abut against the shoulder of the roller.

[0018] Optionally, the support frame has a plurality of first mounting holes, the mounting plate has a plurality of second mounting holes, and the support frame and the mounting plate are connected by bolts passing through the first mounting holes and the second mounting holes.

[0019] Optionally, it also includes:

[0020] The support platform is arranged on one side of the containing tank and along the axis direction of the roller. The support platform and the rotating frame are respectively used to support the two parts of the roller.

[0021] Optionally, it also includes:

[0022] A hanging rod, one end of which is provided on a crane, and the crane is used to drive the hanging rod to move;

[0027] The working principle and beneficial effects of the utility model are as follows:

[0028] In the present invention, during the rotation of the roller, the support frame can support the roller and reduce the deflection of the roller due to its own length and mass. The center of gravity of the rotating frame and the rotation axis of the rotating frame can enable the support frame to maintain a horizontal state without being subjected to force, thereby facilitating the placement of the horizontal roller.

DETAILED DESCRIPTION

[0039] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention.

[0041] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0042] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] Reference Figures 1 to 4 The utility model proposes a roller auxiliary turning device, including: a containing tank 100 for containing quenching liquid; a rotating frame 210 is rotatably arranged relative to the containing tank 100, and the rotating frame 210 is used to support the roller. After the rotating frame 210 rotates, the roller is horizontal or vertical, and the center of gravity of the rotating frame 210 is the rotation axis of the rotating frame 210.

[0044] In this embodiment, during the rotation of the rolling roller, the support frame 230 can support the rolling roller and reduce the deflection of the rolling roller due to its own length and mass. The center of gravity of the rotating frame 210 and the rotation axis of the rotating frame 210 can enable the support frame 230 to maintain a horizontal state without being subjected to force, thereby facilitating the placement of the transverse rolling roller.

[0045] In actual operation, the heated rollers are first placed on the turret 210 in a horizontal position. Then, the turret 210 is rotated relative to the holding tank 100. As the turret 210 rotates, the rollers gradually change from a horizontal position to a vertical position.

[0046] During the entire turning process, the roller is stably supported and gradually turned by the rotating frame 210, thereby avoiding the instability and axial bending problems caused by the long size and large tonnage of the roller itself when it is lifted and turned by a crane and chain as in the prior art.

[0047] In this way, the roll can be smoothly transformed from a horizontal heating state to a vertical quenching state, ensuring that the circumferential hardness of the roll is uniform and meets the modulation process standards.

[0048] After practical application, the axial bending of the roll turned over by using the roll auxiliary turning device has been significantly improved, the quality of the modulated roll has been significantly improved, the service life of the roll has been greatly extended, and the production cost has been reduced.

[0049] Furthermore, it also includes: a baffle 220 is provided on the rotating frame 210, the baffle 220 is located on one side of the rotating axis of the rotating frame 210, and the baffle 220 is used to abut against the shoulder of the roller.

[0050] In this embodiment, the heated rollers are placed on turret 210, which is now horizontal. Baffles 220 abut against the roller shoulders, positioning the rollers axially. Turret 210 is then driven to rotate, gradually shifting the rollers from horizontal to vertical. Once the rollers are horizontal, baffles 220 support them, preventing deformation caused by excessive force from the overhead crane.

[0051] The setting of the baffle 220 effectively prevents the roller from slipping axially during the flipping process, further enhances the flipping stability, ensures that the roller is fixed in position during the flipping process, and will not bend due to axial movement, thereby ensuring that the circumferential hardness of the roller is uniform and meets the modulation process standards.

[0052] Furthermore, the baffle 220 has a positioning groove 221, which is used to abut against the circumferential surface of the roller, and the positioning groove 221 is arc-shaped.

[0053] In this embodiment, the heated roller is placed on the rotating frame 210, with the roller shoulder abutting against the baffle 220. Simultaneously, the roller's circumference abuts against the arc-shaped positioning groove 221. The fit between the positioning groove 221 and the roller's circumference further enhances the roller's positioning and securing.

[0054] When the rotating frame 210 rotates to turn the roller from horizontal to vertical, the positioning groove 221 of the baffle 220 can effectively limit the axial and radial movement of the roller, ensuring that the position of the roller is accurate and stable during the flipping process, avoiding bending, and thus ensuring uniform circumferential hardness of the roller.

[0055] Furthermore, the containing tank 100 is a pit.

[0056] In this embodiment, the holding tank 100 is a pit-shaped structure, which reduces the overall height of the device and facilitates operation and installation. When the turret 210 is driven to rotate the rollers from horizontal to vertical, the pit-shaped holding tank 100 can stably contain the quenching liquid without the increased difficulty of operation due to its excessive height.

[0057] Furthermore, it also includes: there are two support frames 230, which are respectively arranged on both sides of the top of the holding tank 100; there are two rotating shafts 240, one end of the two rotating shafts 240 are respectively arranged at the two ends of the rotating frame 210, and the other ends of the two rotating shafts 240 are respectively rotatably arranged on the support frame 230, and the rotation axes of the two rotating shafts 240 coincide.

[0058] In this embodiment, two rotating shafts 240 are respectively provided at both ends of the rotating frame 210 . The other ends of the two rotating shafts 240 are rotatably provided on the supporting frame 230 , and the rotation axes of the two rotating shafts 240 coincide with each other.

[0059] The design of the two rotating shafts 240 and their precise rotation setting on the support frame 230 provide stable support and precise rotation guidance for the flipping action of the rotating frame 210, ensuring the stability and accuracy of the flipping process.

[0060] Furthermore, the support frame 230 has a slide groove 231 and also includes: a mounting plate 250 that can be detachably set on the support frame 230, the mounting plate 250 has an axial hole 251, the rotation axis of the rotating shaft 240 coincides with the axis of the axial hole 251, the rotating shaft 240 passes through the axial hole 251 and the slide groove 231, and the rotating shaft 240 is rotatably set on the support frame 230 through the mounting plate 250.

[0061] In this embodiment, the mounting plate 250 is detachably mounted on the support frame 230 and has a shaft hole 251. The rotating shaft 240 passes through the shaft hole 251 and the slide groove 231 and is rotatably mounted on the support frame 230 via the mounting plate 250.

[0062] During installation, since the mounting plate 250 is detachable, the rotating shaft 240 is first passed through the slide groove 231 and the shaft hole 251 for preliminary positioning, and then the mounting plate 250 is fixed to the support frame 230. This detachable design makes the installation process flexible and simple, and the installation can be completed without complicated operations.

[0063] Furthermore, the support frame 230 has a plurality of first mounting holes 232 , and the mounting plate 250 has a plurality of second mounting holes 252 . The support frame 230 and the mounting plate 250 are connected by bolts passing through the first mounting holes 232 and the second mounting holes 252 .

[0064] In this embodiment, during the installation process, the rotating shaft 240 is first passed through the slide groove 231 and the shaft hole 251 for preliminary positioning. Then, the second mounting hole 252 of the mounting plate 250 is aligned with the first mounting hole 232 of the support frame 230. Then, bolts are passed through the aligned first mounting hole 232 and the second mounting hole, and nuts are used to secure the mounting plate 250 to the support frame 230. This bolt connection method is simple, reliable, and easy to operate.

[0065] Furthermore, it also includes: a support platform 300 is arranged on one side of the holding tank 100, along the axis direction of the roller, and the support platform 300 and the rotating frame 210 are used to respectively support the two parts of the roller.

[0066] In this embodiment, when the roll needs to be flipped, the roll is first placed horizontally on the turret 210, with one portion of the roll supported by the turret 210 and the other portion supported by the support platform 300. This dual-support structural design can more stably support the roll and further reduce the risk of the roll bending during the flipping process.

[0067] Furthermore, it also includes: one end of the hanging rod 400 is arranged on the overhead crane, and the overhead crane is used to drive the hanging rod 400 to move; the rotating rod 500 is rotatably and slidably arranged at the other end of the hanging rod 400, and the rotation axis of the rotating rod 500 is parallel to the rotation axis of the rotating frame 210; there are at least two clamps 600, which are arranged in sequence at an interval at one end of the rotating rod 500 away from the hanging rod 400, and the clamps 600 are used to clamp the roller.

[0068] In this embodiment, the clamp 600 can be used to clamp the horizontal roller to facilitate the overhead crane to drive the roller to move. The rotating rod 500 is slidably set at the other end of the hanging rod 400. The center of gravity of the roller can be adjusted by adjusting the relative position of the rotating rod 500 and the hanging rod 400, so that the roller can move horizontally.

[0069] As the overhead crane drives the hanging rod 400 to move above the turret 210, the crane descends, bringing the rolls into contact with the turret 210. The rotating rod 500 is then slid to adjust its axis of rotation, thereby positioning the clamping jaws 600 to rotate the rolls under the influence of gravity. The sliding and rotation of the rotating rod 500 allows the angle of the rolls to be adjusted to better coordinate with the turret 210 and support platform 300 for the rollover operation.

[0070] It should be further explained that one end of the hanging rod 400 needs to be fixed on the overhead travelling crane.

[0071] Furthermore, along the distribution direction of the clamping jaws 600, there is an opening on one side of the rotating rod 500. After the rotating rod 500 rotates, the hanging rod 400 enters or leaves the opening. It also includes: one end of the telescopic member 700 is set at the end of the rotating rod 500 away from the opening, and the other end is set on the hanging rod 400. After the telescopic member 700 is extended and retracted, it pushes the rotating rod 500 to slide relative to the hanging rod 400.

[0072] In this embodiment, the sliding rod slides relative to the hanging rod 400 through the telescopic member 700, and the rotating rod 500 has an opening on one side. When the roller rotates to a vertical state, the opening can prevent the hanging rod 400 from interfering with the rotating rod 500.

[0073] It should be further explained that, by adding a limiting member, the rotation angle of the rotating frame 210 can be limited to prevent the rotating frame 210 from shaking continuously, thereby affecting the quality of the roller.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
