[0002] Steel rolling is the process of changing the shape of steel ingots and billets between rotating rollers. The purpose of steel rolling is the same as other pressure processes. On the one hand, it is to obtain the required shape, such as steel plates, strips, wires and various steel sections; on the other hand, it is to improve the internal quality of steel.
[0003] The billet from the steel mill is only a semi-finished product. It must be rolled in the rolling mill to become a qualified product. The continuous casting billet sent from the steel mill first enters the heating furnace, and then enters the finishing mill after repeated rolling in the primary rolling mill. The roller is the main working part and tool on the rolling mill that causes the metal to undergo continuous plastic deformation. Among them, the roller manufactured for the production of steel mainly consists of two parts: the roller ring and the mandrel. This type of roller uses the roller ring to roll the steel. In this case, the roller ring is the middle part of the roller that actually participates in the rolling of the metal. It has a smooth cylindrical or grooved surface. The mandrel is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The transmission end shaft head is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roller.
[0004] However, in order to improve the stability of the roller ring during the steel rolling process, the existing connection between the roller ring and the core shaft is relatively firm, and replacement is inconvenient, which urgently needs improvement. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0038] Please also read Figures 1 to 3 , the auxiliary tooling for roller ring replacement provided by the utility model is now described. An exemplary structure of the auxiliary tooling for roller ring replacement includes a bracket 1, a positioning mechanism 2 and a pushing mechanism 3, wherein the bracket 1 includes a rectangular frame for accommodating the roller 4 to be replaced; the positioning mechanism 2 can fix the roller ring 41 of the roller 4, and includes two groups of positioning components 21 arranged in a mirrored manner on the left and right sides of the bracket 1, each group of positioning components 21 includes a positioning member 212 and a locking member 211 that can approach or move away from the positioning member 212 in the up and down direction, the positioning member 212 is fixed on the top of the bracket 1, and the locking member 211 is movably arranged on the bracket 1 and is located below the positioning member 212; the pushing mechanism 3 is arranged at the bottom of the bracket 1, and can push the roller shaft 42 of the roller 4 to move relative to the roller ring 41 in the up and down direction.
[0039] Compared with the prior art, the roller ring replacement auxiliary tooling provided by the utility model has the beneficial effect that after the roller 4 is transferred to the support 1, the locking member 211 and the positioning member 212 cooperate with each other to fix the roller ring 41 from both the top and bottom sides, preventing the roller 4 from falling off the support 1, thereby ensuring the personal safety of the operator. In addition, the roller ring 41 can be pushed by the push mechanism 3 to produce an axial displacement relative to the roller shaft 42, so that the roller ring 41 falls off the roller shaft 42. The above operation process is quick, convenient, safe and reliable, and can solve the technical problem of the inconvenience of removing the existing roller ring 41 from the roller 4.
[0040] At the same time, since the roller ring 41 in this embodiment is fixed by the positioning mechanism 2, it will not fall off the bracket 1 after falling off from the roller shaft 42, which is convenient for taking and placing in the next step.
[0041] In some embodiments, the pushing mechanism 3 includes a driving member 31 and a top plate 32 for pushing the roller shaft 42 to move relative to the roller ring 41. Specifically, the driving member 31 includes a push rod 311 movably arranged at the bottom of the frame along the up and down directions, and the axial direction of the push rod 311 is parallel to the up and down directions; the top plate 32 is arranged at the top of the push rod 311, and the plate surface of the top plate 32 is perpendicular to the up and down directions.
[0042] In this embodiment, the driving member 31 pushes the top plate 32 to provide an upward axial thrust to the roller shaft 42. With the cooperation of the positioning member 212, the roller shaft 42 moves upward, thereby generating an axial misalignment with the roller ring 41, so that the roller ring 41 is removed from the shaft.
[0043] In some embodiments, the pushing mechanism 3 also includes a guide block 33 and a guide rod 34 that can guide the up and down movement of the push rod 311. In a specific implementation, the guide block 33 is fixed to the bottom of the top plate 32 and is mirrored on the left and right sides of the push rod 311; the guide rod 34 is fixed to the frame, the axial direction of the guide rod 34 is parallel to the up and down direction, and the guide rod 34 slides through the guide block 33.
[0044] Compared with the prior art, the push rod 311 drives the guide block 33 to move up and down during the up and down movement, and the guide slide guides the movement on the guide rod 34, thereby guiding the up and down movement path of the push rod 311 to prevent the push rod 311 from generating radial deviation during the process of pushing the roller ring 41.
[0045] In some embodiments, see Figure 2 The positioning assembly 21 also includes a first connecting member 213, which is used to form a connection between the locking member 211 and the frame. One end of the first connecting member 213 in the length direction is connected to the left frame or the right frame of the frame, and the other end faces the middle of the frame and is used to connect the locking member 211.
[0046] In this embodiment, by providing the first connecting member 213, the locking member 211 can be installed at a suitable position on the frame, which is conducive to positioning the roller ring 41 of the roller 4 to be replaced on the frame.
[0047] In some embodiments, the locking member 211 is a bolt member and is threadedly connected to the first connecting member 213 . The axial direction of the locking member 211 is parallel to the up-down direction.
[0048] This embodiment can position the roller ring 41 of different axial specifications by adjusting the screwing depth of the locking member 211 on the first connecting member 213, thereby facilitating the improvement of the application scope of the utility model to rollers 4 of different specifications.
[0049] In some embodiments, another embodiment is provided to drive the locking member 211 to move. For details, please refer to Figure 3 and Figure 4 The positioning assembly 21 includes an operating rod 214 swingably connected to the frame, the axis of the swing shaft 215 of the operating rod 214 is parallel to the horizontal direction and perpendicular to the axial direction of the operating rod 214, one end of the operating rod 214 facing the frame is the active end, and the other end is the operating end; the locking member 211 is set as a bolt member and is screwed to the active end of the operating rod 214, and the axial direction of the locking member 211 is perpendicular to the axis of the swing shaft 215.
[0050] In this embodiment, the locking member 211 can be driven to move up and down by swinging the operating rod 214 , which is easy to operate and can improve the replacement efficiency of the roller ring 41 .
[0051] It should be noted that, when applying the above embodiment, since the screwing depth of the locking member 211 on the operating rod 214 is adjustable, the screwing depth of the locking member 211 can be adjusted to: when the locking member 211 and the positioning member 212 clamp the roller 4, the axial direction of the operating rod 214 is just parallel to the up and down direction. Optionally, the operating rod 214 can be manually fixed, because the replacement process of the roller ring 41 does not take too long. At the same time, since the operating end of the operating rod 214 is located on the outside of the rectangular frame, the safety of the operator can also be effectively guaranteed. Of course, according to the specific usage scenario, it is also a feasible implementation method to set a cross bar on the side of the frame body to fix the operating rod 214, which will not be further elaborated here.
[0052] In some embodiments, the operating end of the operating rod 214 is hinged with a second connecting member 216, the axis of the hinge shaft 217 of the second connecting member 216 is parallel to the axis of the swing shaft 215, and the second connecting member 216 is a cylindrical member with threads formed inside, and is threadedly adapted to the locking member 211.
[0053] This embodiment utilizes the swing connection between the second connecting member 216 and the operating rod 214 to enable the locking member 211 to be swingably connected to the operating rod 214, so that the top end of the locking member 211 can abut against the axial end surface of the roller ring 41 with different diameters.
[0054] In specific implementation, the swing angle of the second connecting member 216 on the operating rod 214 is limited and is no greater than 45°, so as to prevent the locking member 211 and the second connecting member 216 from being subjected to excessive radial shear force.
[0055] In some embodiments, the frame includes two horizontal beams 11 and two vertical beams 12 arranged in a rectangular shape, the positioning mechanism 2 is arranged on the vertical beams 12, the top plate 32 is located between the two vertical beams 12, and the driving member 31 is arranged on the bottom horizontal beam 11. The frame formed by overlapping the two horizontal beams 11 and the two vertical beams 12 arranged in a rectangular shape can ensure the structural strength of the bracket 1 and provide sufficient installation space for each component in the positioning mechanism 2 and the pushing mechanism 3.
[0056] In some embodiments, the positioning assembly 21 further includes a top block 219 connected to the top of the locking member 211 through a ball joint 218. When the locking member 211 is about to abut against the roller ring 41, the top block 219 in this embodiment can fit the lower end surface of the roller ring 41 by means of the rotational cooperation with the locking member 211, thereby enhancing the clamping effect of the locking member 211 and the positioning member 212 on the roller ring 41.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
