Description

Technical Field

[0001] This invention relates to the field of rolling mill technology, and more specifically to rolling mill stands. Background Technology

[0002] A rolling mill is a piece of equipment used to realize the metal rolling process. It generally refers to the equipment that completes the entire process of rolled material production. Rolling mills can be classified according to the number of rolls, such as two-roll, four-roll, six-roll, eight-roll, twelve-roll, and eighteen-roll mills. A typical rolling mill mainly consists of rolls, a frame, roll gap adjustment devices, roll temperature adjustment devices, transmission devices, lubrication systems, control systems, and roll removal devices. Precision rolling mills, in addition to the main components and devices of a typical rolling mill, add devices to ensure rolling accuracy. They are named according to the type of rolled material, mill type, and nominal size. For section mills, the "nominal size" principle is based on the pitch circle diameter of the herringbone gear in the gear seat; for primary rolling mills, it is based on the nominal diameter of the rolls; for strip mills, it is based on the length of the working rolls; and for pipe mills, it is based on the maximum pipe diameter produced, and sometimes on the inventor of the mill. A rolling mill requires a frame for support and installation; the frame is an important component of the rolling mill.

[0003] A search revealed a patent document (authorization announcement number CN 214556266 U) disclosing a special steel rolling mill frame that is easy to install. The frame includes a first frame body, a second frame body is provided on one side of the first frame body, a base plate is provided at the lower end of both the first and second frame bodies, and the base plate is fixedly connected to both the first and second frame bodies, a base is provided at the lower end of the base plate, a crossbeam is provided on one side of the base plate, and the crossbeam is fixedly connected to the base plate, a limit plate is provided at the lower end of the crossbeam, a caster wheel mechanism is provided below the limit plate, and a threaded post is provided between the caster wheel mechanism and the limit plate.

[0004] When the above-mentioned frame is in use, the position and height of the universal wheel mechanism can be adjusted by driving the threaded column to rotate, thereby facilitating the movement of the first frame body and the second frame body. After the first frame body and the second frame body are moved to the corresponding positions, the threaded column is driven to reset, and then the knob is driven to rotate, so that the knob limits the position of the first frame body and the second frame body. However, this operation method is relatively cumbersome, requiring the operator to operate the threaded column to rotate and drive the knob to rotate in sequence, which is inconvenient to use.

[0005] To address this issue, we propose a rolling mill stand that solves the problems of cumbersome operation and inconvenience in the use of existing rolling mill stands. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The operation of existing rolling mill stands is rather cumbersome, requiring operators to sequentially rotate the threaded column and drive the knobs, making them inconvenient to use.

[0008] (II) Technical Solution

[0009] To address the above problems, the present invention provides the following technical solution:

[0010] A rolling mill stand includes a base, a locking mechanism, and a stand body slidably mounted on the base. The locking mechanism is used to lock the position of the stand body on the base, wherein:

[0011] The locking component includes a crossbeam rotatably mounted on the frame body. The frame body has a receiving groove, and the base has a sliding groove that communicates with the receiving groove. One end of the crossbeam extends into the receiving groove. A limit rod is movably mounted inside the receiving groove, and the top of the limit rod abuts against the end of the crossbeam located inside the receiving groove. A moving rod is movably mounted on the frame body, and the top of the moving rod abuts against the end of the crossbeam located outside the receiving groove. A traveling wheel is rotatably mounted at the bottom of the moving rod.

[0012] The crossbeam has a first working state and a second working state. When the crossbeam is in the first working state, the traveling wheel at the bottom of the moving rod is pressed against the ground, and the limiting rod is away from the inner wall of the bottom of the slide. When the crossbeam is in the second working state, the traveling wheel at the bottom of the moving rod is away from the ground, and the limiting rod is pressed against the inner wall of the bottom of the slide.

[0013] As a further embodiment of the present invention: a mounting bracket is fixedly provided on the receiving groove, and the limiting rod is vertically arranged and movably mounted on the mounting bracket; an assembly groove is opened at the bottom of the frame body, and the moving rod is vertically arranged and movably mounted on the assembly groove.

[0014] As a further aspect of the present invention: a drive gear is rotatably mounted on the assembly slot, and a rack that meshes with the drive gear is fixedly provided on the side of the moving rod.

[0015] As a further aspect of the present invention, it also includes a clamping assembly, which includes two clamping blocks arranged opposite to each other and slidably mounted on the bottom inner wall of the slide groove. The slide groove is provided with an elastic element for driving the two clamping blocks closer to each other. When the crossbeam is in the first working state, the bottom of the limiting rod is pressed against the two clamping blocks.

[0016] As a further aspect of the present invention: the bottom of both clamping blocks is provided with inclined surfaces, and the two inclined surfaces are arranged in an inverted V-shape. The bottom of the limiting rod is provided with two auxiliary wheels, and the two auxiliary wheels are respectively arranged in a one-to-one correspondence with the two inclined surfaces. When the crossbeam is in the first working state, the two auxiliary wheels at the bottom of the limiting rod abut against the corresponding inclined surfaces.

[0017] As a further aspect of the present invention: the elastic element includes two return springs, one end of each return spring is fixedly connected to the slide groove, and the other end of each return spring is fixedly connected to the side of each of the two clamping blocks that are far apart from each other.

[0018] As a further aspect of the present invention: when the crossbeam is in the second working state, the traveling wheel at the bottom of the moving rod is away from the ground, the limiting rod abuts against the bottom inner wall of the slide groove, and the two clamping blocks are located on both sides of the limiting rod and abut against the limiting rod.

[0019] As a further aspect of the present invention: two straight grooves are formed on the bottom inner wall of the slide, and groove blocks are slidably installed on both straight grooves, and two clamping blocks are respectively fixedly installed on the top of the two groove blocks.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. With the crossbeam, limit rod, and moving rod in place, when it is necessary to adjust the position of the main frame on the base, the moving rod can be driven to move vertically upward. The vertical upward movement of the moving rod can drive the crossbeam to rotate counterclockwise, thereby driving the limit rod to move downward until the bottom of the limit rod presses against the inner wall of the bottom of the slide. This pressing action can create friction between the limit rod and the base, so that the main frame is stably placed on the base. When the moving rod is driven to move vertically downward until the traveling wheel at the bottom of the moving rod presses against the ground, it is convenient for subsequent movement. At this time, the limit rod will also move upward to reset under the action of the return spring, releasing the pressing action between it and the slide, making it convenient for the main frame to adjust its position on the base.

[0023] 2. By setting two clamping blocks, after the limit rod moves downward until it presses against the inner wall of the bottom of the slide, the two clamping blocks will clamp and press the limit rod, so that the connection force between the limit rod and the base is not limited to the friction force at its bottom, which improves the stability of the frame body on the base and facilitates the stable use of the frame body in the future.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-5 As shown, the rolling mill frame includes a base 1, a locking mechanism, and a frame body 2 slidably mounted on the base 1. The locking mechanism is used to lock the position of the frame body 2 on the base 1. During assembly, the frame body 2 and the base 1 can be hoisted to the corresponding position as a whole. Since the frame body 2 is slidably mounted on the base 1, the position of the frame body 2 on the base 1 can be adjusted to the corresponding usage position during fine-tuning. After adjustment, the locking mechanism can be used to self-lock the position of the frame body 2 on the base 1, making the operation simple.

[0033] Regarding the aforementioned locking mechanism, the locking mechanism includes a crossbeam 3, which is rotatably mounted on the frame body 2. The frame body 2 has a receiving groove 4, and the base 1 has a sliding groove 5, which is connected to the receiving groove 4. One end of the crossbeam 3 penetrates into the receiving groove 4. A limiting rod 6 is movably installed inside the receiving groove 4, and the top of the limiting rod 6 abuts against the end of the crossbeam 3 located inside the receiving groove 4. A moving rod 7 is movably installed on the frame body 2, and the top of the moving rod 7 abuts against the end of the crossbeam located outside the receiving groove 4. A traveling wheel 8 is rotatably installed at the bottom of the moving rod 7.

[0034] The crossbeam 3 has a first working state and a second working state. When the crossbeam 3 is in the first working state, that is... Figure 1 In the state shown, the traveling wheel 8 at the bottom of the moving rod 7 is pressed against the ground, and the limiting rod 6 is away from the inner wall of the bottom of the slide 5. At this time, the traveling wheel 8 can be used to smoothly drive the frame body 2 to move on the two bases 1, realizing the fine adjustment of the position of the frame body 2 on the base 1; when the crossbeam 3 is in the second working state, that is Figure 4 In the state shown, the traveling wheel 8 at the bottom of the moving rod 7 is away from the ground, and the limiting rod 6 is pressed against the inner wall of the bottom of the slide 5. At this time, under the pressing action of the limiting rod 6 against the inner wall of the bottom of the slide 5, there is a large friction between the limiting rod 6 and the inner wall of the bottom of the slide 5. Under the action of this friction, the position of the frame body 2 can be well locked and limited, which facilitates the subsequent use of the frame body 2.

[0035] Under normal use, the main body between the frame body 2 and the base 1 is as follows: Figure 4 As shown, the bottom of the limiting rod 6 locks the base 1 to the frame body 2, allowing the frame body 2 to be used normally; Figure 4 In the indicated state, the moving rod 7 can be driven downwards until the traveling wheel 8 at the bottom of the moving rod 7 presses against the ground. At this time, the crossbeam 3 will rotate clockwise, thereby eliminating the pressing effect on the limit rod 6. This state can be achieved by... Figure 1 This indicates that, at this time, the frame body 2 can be moved and adjusted on the base 1 by relying on the traveling wheels 8; Figure 1 In the indicated state, driving the moving rod 7 upward, under the pressure of the top of the moving rod 7, causes the crossbeam 3 to rotate counterclockwise. At this time, the left end of the crossbeam 3 will press against the limiting rod 6 and move downward until the bottom of the limiting rod 6 presses against the inner wall of the bottom of the slide groove 5. Under this pressure, the frame body 2 can be stably placed on the base 1. This state can be achieved by... Figure 4 The status is as shown.

[0036] To facilitate the installation of the limiting rod 6 and the moving rod 7, a mounting bracket 9 can be fixedly installed on the receiving groove 4. The limiting rod 6 is vertically arranged and movably mounted on the mounting bracket 9. An assembly groove 10 is provided at the bottom of the frame body 2, and the moving rod 7 is vertically arranged and movably mounted on the assembly groove 10.

[0037] Meanwhile, to achieve the vertical up-and-down movement of the movable rod 7, a drive gear 11 can be rotatably mounted on the assembly slot 10, and a rack 12 meshing with the drive gear 11 is fixedly installed on the side of the movable rod 7. An external drive motor (not shown in the figure) can rotate the drive gear 11, which in turn drives the meshing rack 12 to move up and down, thereby achieving the vertical up-and-down movement of the movable rod 7. Of course, the vertical movement of the movable rod 7 is not limited to using a drive gear 11 and rack 12; they can be replaced with other conventional techniques from the prior art, as long as the vertical up-and-down movement of the limiting rod 6 is achieved.

[0038] Furthermore, in order to enable the limiting rod 6 to self-reset and move upward when the crossbeam 3 rotates clockwise, and to increase the pressure force between the limiting rod 6 and the slide groove 5, the present invention also includes a clamping assembly. The clamping assembly includes two clamping blocks 13, which are arranged opposite to each other and slidably mounted on the bottom inner wall of the slide groove 5. Specifically, two straight grooves 17 are formed on the bottom inner wall of the slide groove 5, and groove blocks 18 are slidably mounted on each of the two straight grooves 17. The two clamping blocks 13 are respectively fixedly mounted on the top of the two groove blocks 18. An elastic element is provided inside the slide groove 5 to drive the two clamping blocks 13 closer to each other. When the crossbeam 3 is in the first working state, that is... Figure 1 In the state shown, the bottom of the limiting rod 6 is pressed against the two clamping blocks 13, and the elastic element is always in a compressed state.

[0039] exist Figure 1 In the indicated state, if the moving rod 7 is driven upwards, the left end of the crossbeam 3 will press downwards against the limiting rod 6. The limiting rod 6 can then press downwards, causing the two clamping blocks 13 to move away from each other until the bottom of the limiting rod 6 presses against the bottom inner wall of the slide groove 5. At this point, the elastic element will be further compressed. This state can be achieved by... Figure 4 To illustrate, under the action of the elastic element, the two clamping blocks 13 can be driven to press against the bottom of the limiting rod 6. This pressing action will increase the locking force between the frame body 2 and the base 1, which will facilitate the subsequent use of the frame body 2.

[0040] To ensure smooth downward movement of the limiting rod 6, inclined surfaces 14 are provided at the bottom of both clamping blocks 13, arranged in an inverted V-shape. Two auxiliary wheels 15 are rotatably mounted at the bottom of the limiting rod 6, each corresponding to one of the two inclined surfaces 14. When the crossbeam 3 is in its first working state, that is... Figure 1 In the indicated state, the two auxiliary wheels 15 at the bottom of the limiting rod 6 press against the corresponding inclined surfaces 14. When the crossbeam 3 rotates counterclockwise to drive the limiting rod 6 to move downward, the two auxiliary wheels 15 at the bottom of the limiting rod 6 can roll on the corresponding inclined surfaces 14 until they press against the inner wall of the bottom of the slide groove 5. At this time, the two clamping blocks 13 can clamp and limit the bottom of the limiting rod 6, and the elastic element is further compressed.

[0041] Regarding the aforementioned elastic element, the elastic element includes two return springs 16. One end of each return spring 16 is fixedly connected to the slide groove 5, and the other end of each return spring 16 is fixedly connected to the opposite side of each of the two clamping blocks 13. During the downward movement of the limiting rod 6, the limiting rod 6 will press against the movement of the two clamping blocks 13 away from each other, and the return springs 16 will be further compressed during this process. Then, during the downward movement of the moving rod 7, the two return springs 16 can drive the two clamping blocks 13 to move closer to each other. The closer movement of the two clamping blocks 13 can cause the limiting rod 6 to move upward. The upward movement of the limiting rod 6 can drive the crossbeam 3 to rotate clockwise, thus achieving self-reset.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
