Description

Technical Field

[0001] This utility model relates to the field of ring rolling mill technology, and in particular to a centering and positioning mechanism for a vertical ring rolling mill. Background Technology

[0002] In the traditional ring rolling process, the annular part is placed between the vertically arranged main roller and core roller, and is positioned with the assistance of side rollers. Existing technology usually uses rotating roller brackets to directly support the annular part. For example, utility model patent application No. 202421780621.1 discloses a vertical ring rolling mill holding roller positioning device, including a vertical worktable, a main roller installed on the front side of the vertical worktable, a core roller arranged on the lower side of the main roller, and roller brackets inserted into a fixed shaft to achieve the support and positioning of the annular part. However, it does not take into account that the annular part is prone to horizontal displacement during radial rolling, resulting in low centering accuracy and uneven wall thickness and excessive ellipticity. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a centering and positioning mechanism for a vertical ring rolling mill, so as to solve the technical problem that the existing technology does not take into account the horizontal offset of the ring part during radial rolling, resulting in low centering accuracy, uneven wall thickness and excessive ellipticity.

[0004] To achieve the above objectives, this utility model provides a centering and positioning mechanism for a vertical ring rolling mill, including a vertical worktable. A main roller is mounted on the front side of the vertical worktable, a core roller is provided on the lower side of the main roller, and support roller bodies are provided on both sides of the core roller. Two support roller bodies are symmetrically arranged on both sides of the core roller via rotating arms. The rotating arms are rotatably located at the side end of the vertical worktable. The centering and positioning mechanism further includes:

[0005] A pressure-bearing seat is provided at the lower part of the vertical workbench;

[0006] A mounting base is slidably mounted on the pressure seat, and a push plate is detachably mounted on the mounting base. The horizontal movement center line of the push plate is collinear with the projection center lines of the main roller and the core roller.

[0007] A drive unit 1 for driving the rotating arm to rotate;

[0008] Drive unit two for driving the mounting base to slide.

[0009] Furthermore, the core roller is used to hang the annular component of the ring to be rolled, the top of the annular component abuts against the main roller, and the lower two sides of the annular component abut against the idler roller body.

[0010] Furthermore, the drive unit one includes:

[0011] A drive motor is located on the back of the vertical worktable;

[0012] A lead screw is coaxially mounted at the output end of the drive motor, and the other end of the lead screw is rotatably mounted on the vertical workbench.

[0013] A lifting block threaded onto the lead screw;

[0014] Connecting rods are hinged to both sides of the lower part of the lifting block, and the other end of the connecting rods is fixedly connected to the rotating arm.

[0015] Furthermore, the projection center line of the lead screw in the horizontal direction is placed at the exact center of the vertical worktable.

[0016] Furthermore, the second driving unit includes:

[0017] A second drive motor is located at the lower part of the vertical workbench;

[0018] A lead screw two is coaxially mounted at the output end of the drive motor two, and the other end of the lead screw two is rotatably mounted on the vertical workbench;

[0019] The mounting base is threaded onto the second lead screw.

[0020] Furthermore, the lower part of the vertical workbench is also provided with a guide column, and the mounting base is slidably disposed on the guide column.

[0021] Furthermore, the pressure bearing seat is provided with a guide opening, and the pressure bearing seat is slidably positioned within the guide opening.

[0022] Furthermore, the push plate has an L-shaped structure, and the end face of the push plate mates with the side of the annular component.

[0023] The beneficial effects of this utility model are as follows: In use, the drive unit drives the rotating arm to rotate, thereby driving the roller body to rotate synchronously. Since the two roller bodies are symmetrically arranged on both sides of the core roller through the rotating arm, the automatic centering of the annular part to be rolled can be realized. At the same time, the drive unit drives the mounting seat to slide, thereby limiting the side end face of the annular part to be rolled, avoiding the situation that vibration or falling off is easy to occur during high-speed rotation due to the small contact area between the annular part and the roller body. The centering accuracy is high, ensuring the rolling quality of the annular part. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] The first aspect of this utility model proposes a centering and positioning mechanism for a vertical ring rolling mill, such as... Figure 1-4 As shown, the system includes a vertical worktable 1, a main roller 2 mounted on the front side of the vertical worktable 1, a core roller 3 mounted on the lower side of the main roller 2, and support roller bodies 4 mounted on both sides of the core roller 3. The two support roller bodies 4 are symmetrically positioned on both sides of the core roller 3 via rotating arms 5, which are rotatably mounted on the side ends of the vertical worktable 1. The centering and positioning mechanism also includes:

[0034] A pressure-bearing seat 6 is located at the bottom of the vertical workbench 1;

[0035] A mounting base 7 is slidably mounted on the pressure seat 6. A push plate 8 is detachably mounted on the mounting base 7. The horizontal movement center line of the push plate 8 is collinear with the projection center lines of the main roller 2 and the core roller 3.

[0036] Drive unit 1 for driving the rotating arm 5 to rotate;

[0037] Drive unit 2 for driving the mounting base 7 to slide.

[0038] In this embodiment, during use, the drive unit drives the rotating arm 5 to rotate, thereby driving the roller body 4 to rotate synchronously. Since the two roller bodies 4 are symmetrically arranged on both sides of the core roller 3 via the rotating arm 5, the annular part 9 of the ring to be rolled can be automatically centered. At the same time, the drive unit drives the mounting base 7 to slide, thereby limiting the side end face of the annular part 9 of the ring to be rolled, avoiding vibration or detachment during high-speed rotation due to the small contact area between the annular part 9 and the roller body 4.

[0039] In this embodiment, as Figure 1 As shown, the core roller 3 is used to hang the annular part 9 of the ring to be rolled. The top of the annular part 9 abuts against the main roller 2, and the lower two sides of the annular part 9 abut against the idler roller body 4.

[0040] In this embodiment, as Figure 2 As shown, the drive unit includes:

[0041] Drive motor 10 is located on the back of the vertical worktable 1;

[0042] A lead screw 11 is coaxially mounted at the output end of the drive motor 10, and the other end of the lead screw 11 is rotatably mounted on the vertical worktable 1.

[0043] The lifting block 12 is threaded onto the lead screw 11;

[0044] The connecting rods 13 are hinged to both sides of the lower part of the lifting block 12. The other end of the connecting rods 13 is fixedly connected to the rotating arm 5. The output end of the drive motor 10 drives the lead screw 11 to rotate, which in turn drives the lifting block 12 to perform lifting and lowering actions. Thus, the connecting rods 13 drive the rotating arm 5 and the corresponding side roller body 4 to rotate.

[0045] In this embodiment, as Figure 2 As shown, the projection center line of the lead screw 11 in the horizontal direction is placed at the exact center of the vertical worktable 1 to ensure centering accuracy.

[0046] In this embodiment, as Figure 3 As shown, the second drive unit includes:

[0047] Drive motor 214 is located at the lower part of the vertical worktable 1;

[0048] A lead screw 15 is coaxially mounted at the output end of the drive motor 14, and the other end of the lead screw 15 is rotatably mounted on the vertical worktable 1.

[0049] The mounting base 7 is threaded onto the lead screw 15. The output end of the drive motor 14 drives the lead screw 15 to rotate, which in turn drives the mounting base 7 and the corresponding push plate 8 to move horizontally. This avoids vibration or detachment during high-speed rotation due to the small contact area between the annular part 9 and the roller body 4.

[0050] In this embodiment, as Figure 3 As shown, the lower part of the vertical workbench 1 is also provided with a guide column 16, and the mounting base 7 is slidably mounted on the guide column 16 to ensure the stability of the push plate 8 in horizontal movement.

[0051] In this embodiment, the pressure bearing seat 6 is provided with a guide opening 17, and the pressure bearing seat 6 is slidably positioned within the guide opening 17. The push plate 8 has an L-shaped structure, and the end face of the push plate 8 cooperates with the side of the annular part 9 to avoid aggravating the vibration of the annular part 9.

[0053] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
