Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a bearing and bushing separation device for steel rolling assembly. Background Technology

[0002] Bearings used in steel rolling assembly are key mechanical components in steel industry production equipment. Their performance directly affects the efficiency and quality of steel rolling production. With the development of the steel industry, steel rolling equipment faces higher requirements for production efficiency and stability. Bearings need to withstand harsh working conditions such as huge rolling forces, high temperatures, and high-speed impacts. In the steel rolling mill of the steel bar and wire rod production workshop, improper use can lead to bearing burnout accidents, which can cause the bushing and the mill thrust bearing to stick together, making it difficult to separate and replace the bearing.

[0003] Traditional separation methods for disassembling rolling mill thrust bearings and bushings typically involve cutting or hammering, which can severely damage the bearings themselves and may lead to operational accidents, thus reducing the efficiency and practicality of the disassembly process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bearing and bushing separation device for rolling mill assembly. This solves the problem that the traditional separation method, which typically uses cutting tools or hammering to separate the rolling mill thrust bearing and bushing, not only causes serious damage to the bearing itself but may also lead to operational accidents, thus reducing the efficiency and practicality of the separation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing and bushing separation device for steel rolling assembly, comprising an annular stamping table, wherein two limiting short rods are welded to each other at the outer surface of the annular stamping table near the top edge, and further comprising: An adjustable support assembly includes two support plates, each movably sleeved on the outer surface of a limiting short rod. The adjustable support assembly is used to provide support for the stamping separation assembly. A stamping separation assembly includes a one-way lead screw, which is threadedly connected to an adjustment bracket assembly. The stamping separation assembly is used to control the adjustment of downward pressure to separate the bearing from the bushing.

[0006] Preferably, a bidirectional lead screw is threaded between the opposite sides of the two frame plates near the center, and a connecting groove is formed on the outer surface of the bidirectional lead screw near the center.

[0007] Preferably, a torsion block is fixedly welded to one end of the bidirectional lead screw.

[0008] Preferably, a collar is movably fitted on the outer surface of the connecting groove, and a first annular limiting block is fixedly welded to the outer surface of the collar.

[0009] Preferably, a limit rod is slidably provided at the edge near the top of each of the two frame plates on opposite sides, and a second annular limit block is fixedly welded between the opposite ends of the two limit rods.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1: Please see Figure 1-3 A bearing and bushing separation device for steel rolling assembly includes an annular stamping table 1, with two limiting short rods 2 welded to each other near the top edge of the outer surface of the annular stamping table 1, and further includes: Adjustable support assembly 3 includes support plate 31. There are two support plates 31. Both support plates 31 are movably sleeved on the outer surface of the limiting short rod 2. Adjustable support assembly 3 is used to provide support for the stamping separation assembly 4. The stamping separation assembly 4 includes a one-way lead screw 41, which is threadedly connected to the adjustment bracket assembly 3. The stamping separation assembly 4 is used to control the adjustment of the downward pressure to separate the bearing from the bushing. In this embodiment, by setting the annular stamping table 1, the bearing that needs to be separated can be placed on the top of the annular stamping table 1, so that the bushing is mounted at the top center of the annular stamping table 1. This makes it easier for the stamping separation assembly 4 to separate the bearing and bushing when it presses downward. The setting of the limiting short rods 2 on both sides makes it easier to adjust the mounting assembly 3, which plays an auxiliary positioning role.

[0017] Example 2: Please see Figure 1-5 Based on Embodiment 1, this embodiment provides a technical solution: a bidirectional screw rod 32 is threaded between the opposite sides of the two frame plates 31 near the center, a connecting groove 33 is opened on the outer surface of the bidirectional screw rod 32 near the center, and a torsion block 34 is fixedly welded to one end of the bidirectional screw rod 32. A collar 35 is movably fitted on the outer surface of the connecting groove 33, and a first annular limiting block 36 is fixedly welded to the outer surface of the collar 35. Limiting rods 37 are slidably installed at the edges near the top on opposite sides of the two frame plates 31, and a second annular limiting block 38 is fixedly welded between the opposite ends of the two limiting rods 37. The one-way lead screw 41 is threadedly connected to the first annular limiting block 36, and the one-way lead screw 41 is slidably connected to the second annular limiting block 38. A torque handle 42 is fixedly welded to the top of the one-way lead screw 41, and a stamping pad 43 is threadedly connected to the bottom of the one-way lead screw 41. The stamping pad 43 is positioned opposite to the annular stamping table 1; In this embodiment, the two bidirectional lead screws 32 are threadedly connected to the two support plates 31, and the two limiting rods 37 limit the support plates 31. This allows the two bidirectional lead screws 32 to slide in opposite or opposite directions during rotation, thus adapting to different sizes of annular stamping tables 1 and allowing the two support plates 31 to be movably sleeved on the outer surfaces of the two limiting rods 2. The first annular limiting block 36 is threadedly connected to the unidirectional lead screw 41, which limits the unidirectional lead screw 41. The unidirectional lead screw 41 is slidably connected to the second annular limiting block 38, which limits the two limiting rods 37. The connecting groove 33 and the collar 35 are movably sleeved, which provides a supporting effect for the first annular limiting block 36. The stamping pad 43 is threadedly connected to the unidirectional lead screw 41, which facilitates the installation and removal of the stamping pad 43 and allows for the installation of stamping pads 43 of different sizes, thereby matching bearings of appropriate sizes.

[0018] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0019] During operation, during initial assembly, the one-way lead screw 41 can be passed from top to bottom through the second annular limiting block 38. The first annular limiting block 36 is then flipped to be flush with the horizontal plane. By rotating the torque handle 42, the one-way lead screw 41 is rotated, thereby making the one-way lead screw 41 threadedly connected to the first annular limiting block 36. Subsequently, the stamping pad 43 is threadedly fitted and fixed to the bottom end of the one-way lead screw 41. By rotating the torque block 34, the two-way lead screw 32 can be rotated, thereby causing the two frame plates 31 to slide and adjust in opposite directions. The limiting short rods 2 set on both sides of the annular stamping table 1 are used for positioning, so that the bottom ends of the two frame plates 31 are respectively fitted onto the outer surface of the corresponding limiting short rods 2, thus completing the assembly. When it is necessary to separate the bearing and the bushing, the bearing is mounted on the top of the annular stamping table 1, and the bushing is mounted at the center of the top of the annular stamping table 1. The operator holds the handle 42 and tries to make the stamping pad 43 face the bearing below. Finally, the handle 42 is turned to drive the one-way screw 41 to rotate synchronously, so that the stamping pad 43 presses the bushing at the center of the bearing below downward. The force generated by the continuous rotation of the handle 42 successfully separates the bushing from the bearing.
