Description

Technical Field

[0001] The present invention relates to the technical field of guide devices, and more specifically, to a guide device for a finishing mill. Background Art

[0002] During the rolling process of a finishing mill, the guide device plays a crucial role, directly affecting the conveyance of the rolled piece. Traditional guide devices for finishing mills are usually composed of simple components such as a horizontal support plate and clamping plates, aiming to provide basic support and a conveyance adjustment channel for the rolled piece, and to meet the needs of the rolled piece entering the front guide of the finishing mill at one end.

[0003] The support plate in the traditional guide device is generally of a single structure, and its support effect on the rolled piece is relatively simple. During the process of the rolled piece entering the guide device at one end and being conveyed, the rolled piece often generates a large frictional force with the support plate due to its own gravity, increasing the force required to adjust the movement of the rolled piece, causing significant wear to the guiding components of the guide device, shortening the service life of the equipment, and increasing the maintenance cost. Summary of the Invention

[0004] The present invention provides a guide device for a finishing mill, which solves the problems of fast wear speed and low service life of the existing guide device.

[0005] The technical solution of the present invention is as follows: A guide device for a finishing mill, comprising: A support plate for supporting and conveying a strip-shaped rolled piece; Clamping plates arranged on the support plate, with two clamping plates arranged opposite to each other, and a conveying channel for the strip-shaped rolled piece is formed between the two clamping plates; The support plate is divided into a front straight section, an angle adjustment section, and a rear straight section along the conveying direction of the strip-shaped rolled piece, and the angle adjustment section has an inclined state and a horizontal state; The clamping plates are divided into a parallel section and a guiding section along the conveying direction of the strip-shaped rolled piece, the guiding section is located at the rear straight section, the parallel sections of the two clamping plates are parallel to each other, and the distance between the guiding sections of the two clamping plates gradually decreases along the conveying direction of the strip-shaped rolled piece.

[0006] As a further technical solution, When the angle adjustment section is in the inclined state, the end of the angle adjustment section close to the front straight section is higher than the end close to the rear straight section; or The end of the angle adjustment section close to the front straight section is lower than the end close to the rear straight section.

[0007] As a further technical solution, The front straight section and the rear straight section are horizontally arranged, and the inclination angle of the angle adjustment section is adjustable.

[0008] As a further technical solution, An installation groove is formed on the pallet, and further includes: A rolling component, which is arranged in the installation groove and is used for conveying the strip-shaped rolled piece.

[0009] As a further technical solution, the rolling component includes: A shaft body, which is arranged in the installation groove, and the central axis of the shaft body is perpendicular to the conveying direction of the strip-shaped rolled piece; A wheel body, which is rotatably and slidably arranged on the shaft body, and the sliding direction of the wheel body is the axial direction of the shaft body.

[0010] As a further technical solution, the rolling component further includes: A reset component, which acts on the wheel body and is used to provide a reset force for the wheel body after its position changes due to sliding.

[0011] As a further technical solution, The reset component is a spring, the reset spring is sleeved on the shaft body, and one end of the reset component acts on the wheel body.

[0012] As a further technical solution, The wheel body has an annular wheel surface, the diameter of the annular wheel surface gradually decreases from the middle to both sides, and the annular wheel surface is the surface of the wheel body for carrying the strip-shaped rolled piece.

[0013] As a further technical solution, At least two of the wheel bodies are arranged on the shaft body, and the reset components are arranged on both sides of the wheel body.

[0014] As a further technical solution, A plurality of the installation grooves are arranged in parallel, and the rolling components are arranged in all of the plurality of installation grooves. The front straight section, the angle adjustment section, and the rear straight section all have the installation grooves.

[0015] The working principle and beneficial effects of the present invention are as follows: In the present invention, with reference to Figure 1 and Figure 2As shown in the figure, the pallet in the device, as a basic component for carrying strip-shaped rolled products, functions like the cornerstone of a conveyor track, providing a stable support for the rolled products during the entire conveying process. The two relatively arranged clamping plates construct a conveying channel for strip-shaped rolled steel products above the pallet. Just like the fences on both sides of a track, they strictly define the traveling route of the rolled products and ensure that they move forward in a predetermined direction. The pallet is finely divided into a front straight section, an angle adjustment section, and a rear straight section along the conveying direction of the strip-shaped rolled products. The unique inclined layout of the angle adjustment section is not accidental. It is designed based on a deep consideration of the entire rolling process flow. Through this inclined setting, the friction between the strip-shaped rolled products and the rear straight section of the pallet can be reduced, thereby reducing the extrusion force when the guiding section adjusts the direction of the strip-shaped rolled products, reducing the frictional loss of the strip-shaped rolled products on the guiding section of the clamping plates, and at the same time reducing noise. Specifically, when the strip-shaped rolled products pass through the angle adjustment section and reach the rear straight section, without the support of the angle adjustment section, the strip-shaped rolled products will bend under the action of gravity, approach the rear straight section and be conveyed. Because the strip-shaped rolled products themselves have elasticity, when they bend under the action of gravity, the elastic force generated by the bending will offset a part of the gravity, so the pressure of the strip-shaped rolled products on the rear straight section is reduced. With the reduction of pressure, the friction between the strip-shaped rolled products and the rear straight section becomes smaller, so the position adjustment of the strip-shaped rolled products will be easier, thereby reducing the acting force on the guiding section, reducing the wear degree, increasing the service life of the guiding section, and reducing the maintenance cost.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0023] As Figures 1 to 7 shown, the present invention provides a guide device for a finishing mill, including a pallet 1 and a clamping plate 2. The pallet 1 is used to support and convey strip-shaped rolled pieces; the clamping plate 2 is arranged on the pallet 1, and there are two relatively arranged clamping plates 2, and a conveying channel for strip-shaped rolled pieces is formed between the two clamping plates 2; the pallet 1 is divided into a front straight section 11, an angle adjustment section 12, and a rear straight section 13 along the conveying direction of the strip-shaped rolled piece. The angle adjustment section 12 has an inclined state and a horizontal state; the clamping plate 2 is divided into a parallel section 21 and a guiding section 22 along the conveying direction of the strip-shaped rolled piece. The guiding section 22 is located at the rear straight section 13. The parallel sections 21 of the two clamping plates 2 are parallel to each other, and the distance between the guiding sections 22 of the two clamping plates 2 gradually decreases along the conveying direction of the strip-shaped rolled piece.

[0024] In this embodiment, when the angle adjustment section 12 is in an inclined state (the angle adjustment section 12 is swingably arranged and is in an inclined state or a horizontal state after swinging).

[0025] Refer to Figure 1 and Figure 2 As shown, the pallet 1 in the device, as the basic component for carrying the strip-shaped rolled piece, acts like the cornerstone of a conveying track, providing a stable support for the rolled piece during the entire conveying process. The two relatively arranged clamping plates 2 build a conveying channel for the strip steel rolled piece above the pallet 1, just like the fences on both sides of the track, strictly limiting the traveling route of the rolled piece and ensuring its forward movement in a predetermined direction. The pallet 1 is finely divided into a front straight section 11, an angle adjustment section 12, and a rear straight section 13 along the conveying direction of the strip-shaped rolled piece. The unique inclined layout of the angle adjustment section 12 is not accidental. It is designed based on in-depth consideration of the entire rolling process flow. Through this inclined setting, the friction between the strip-shaped rolled piece and the rear straight section 13 of the pallet 1 can be reduced, thereby reducing the extrusion force when the guiding section 22 adjusts the direction of the strip-shaped rolled piece, reducing the frictional loss of the strip-shaped rolled piece on the guiding section 22 of the clamping plate 2, and at the same time reducing noise. Specifically, when the strip-shaped rolled piece passes through the angle adjustment section 12 and reaches the rear straight section 13, without the support of the angle adjustment section 12, the strip-shaped rolled piece will bend under the action of gravity, approach the rear straight section 13 and be conveyed. Because the strip-shaped rolled piece itself has elasticity, when it bends under the action of gravity, the elastic force generated by the bending will offset a part of the gravity, so the pressure of the strip-shaped rolled piece on the rear straight section 13 is reduced. With the pressure reduced, the friction force of the strip-shaped rolled piece on the rear straight section 13 will become smaller, so the position adjustment of the strip-shaped rolled piece will be easier, thereby reducing the acting force on the guiding section 22, reducing the wear degree, increasing the service life of the guiding section 22, and reducing the maintenance cost.

[0026] In addition, it should be noted that during the process when the free end of the strip-shaped rolled piece enters the guide device but does not enter the finishing mill, this guide device plays a role in guiding and adjusting the position and supporting the strip-shaped rolled piece (that is, the angle adjustment section 12 is in an inclined state during this process). After the strip-shaped rolled piece passes through the guide device and enters the finishing mill, the guide device only plays a supporting role (that is, the angle adjustment section 12 is in a horizontal state during this process. When in the horizontal state, the front straight section 11, the angle adjustment section 12, and the rear straight section 13 stably convey the strip-shaped rolled piece horizontally).

[0027] Furthermore, when the angle adjustment section 12 is in an inclined state, the end of the angle adjustment section 12 close to the front straight section 11 is higher than the end close to the rear straight section 13; or the end of the angle adjustment section 12 close to the front straight section 11 is lower than the end close to the rear straight section 13.

[0028] In this embodiment, two tilting methods are provided for the angle adjustment section 12 of the guide device, that is, one end close to the front straight section 11 can be higher or lower than one end close to the rear straight section 13. This flexibility endows the device with stronger adaptability and operability. In different rolling scenarios, the characteristics and process requirements of strip rolling materials vary greatly. For some rolling materials with harder texture and larger thickness, their elastic and deformation characteristics may have different effects on the conveying and guiding processes. When the tilting method with one end close to the front straight section being higher than one end close to the rear straight section is adopted, the self-gravity of the rolling material and the tilting angle can be utilized to make the rolling material enter the rear straight section more smoothly, while reducing the pressure on the rear straight section 13, thereby reducing the friction force and the extrusion force on the guiding section 22. This setting is similar to providing a boost to the rolling material to help it better adapt to subsequent conveying and guiding operations, especially suitable for rolling processes that are more sensitive to friction force and extrusion force, and can more effectively reduce equipment wear and improve product quality.

[0029] Conversely, when one end close to the front straight section 11 is lower than one end close to the rear straight section 13, for some thin and flexible strip rolling materials, this tilting method may be more conducive to controlling the tension and position of the rolling material, and avoiding difficulties in conveying and guiding caused by excessive deformation of the rolling material. This reverse tilting method can adjust the rolling material to a more suitable state according to the elasticity and toughness of the rolling material, ensuring that it will not affect the product quality due to excessive bending or uneven tension during subsequent conveying and guiding processes. By selecting different tilting methods, the device can be optimized according to the specific conditions of the rolling material, which is of great practical significance for improving production efficiency and ensuring product quality, and can better adapt to the production requirements of different products, providing a broader operating space for diversified rolling processes.

[0030] Furthermore, the front straight section 11 and the rear straight section 13 are horizontally arranged, and the tilting angle of the angle adjustment section 12 is adjustable.

[0031] In this embodiment, the front straight section 11 and the rear straight section 13 are horizontally arranged. This characteristic ensures a very smooth transition process when the rolling material enters and leaves the angle adjustment section. When the rolling material enters from one stage to another, the horizontal arrangement can avoid the impact caused by sudden changes in the height of the pallet, enabling the rolling material to maintain a continuous motion state throughout the conveying process, and avoiding problems such as jitter, speed fluctuation, or position deviation of the rolling material caused by this discontinuity, providing stable input and output conditions for subsequent rolling processes. This is crucial for ensuring the dimensional accuracy and surface quality of the product, because any slight jitter or position deviation may be amplified in subsequent rolling and ultimately affect the product quality.

[0032] Meanwhile, the adjustability of the tilt angle of the angle adjustment section 12 is a very important design highlight. Operators can flexibly adjust the tilt angle based on various factors such as the material, thickness, elasticity, rolling speed, temperature of the rolled piece, and the operating status of subsequent equipment. By precisely adjusting the tilt angle, the movement state of the rolled piece in the angle adjustment section 12 can be more finely controlled, thereby further optimizing the physical relationship between the rolled piece and the rear straight section 13. For example, for rolled pieces with different elasticities and hardnesses, the optimal tilt angle can be found to minimize the friction between the strip-shaped rolled piece and the rear straight section 13 and reduce the extrusion force on the guiding section 22. This adjustment can be continuously optimized based on real-time feedback and experience during the actual production process to achieve the goals of reducing equipment wear, improving product quality, and extending the service life of the equipment. It enables the entire guide device to not only adapt to different types of rolled pieces but also maintain efficient and stable operation under different rolling speeds and temperature conditions, providing strong support for achieving precise rolling operations and diverse product production.

[0033] In addition, the angle adjustment section 12 can be adjusted in terms of angle. Optional implementation methods include, for example, the two ends of the angle adjustment section 12 are respectively hinged to the front straight section 11 and the rear straight section 13. By adjusting the heights of the front straight section 11 and the rear straight section 13, the tilt angle of the angle adjustment section 12 can be adjusted. Changing the heights of the front straight section 11 and the rear straight section 13 may affect the position of entering the finishing mill. Then, the position of the front straight section 11 can be fixed, and only the height of the rear straight section 13 needs to be adjusted. For the height change of the rear straight section 13, other devices cooperating with it can make adaptive adjustments (such as the corresponding devices can be lifted and moved, etc.) to cooperate with the height change of the rear straight section 13.

[0034] Furthermore, after the angle adjustment section 12 completes the guide function for the strip-shaped rolled piece, it can be adjusted to a horizontal state, so that the front straight section 11, the angle adjustment section 12, and the rear straight section 13 are located on the same plane, completing the horizontal transportation of the strip-shaped rolled piece and making the overall operation more stable and reliable.

[0035] Furthermore, an installation groove 14 is formed on the support plate 1, and a rolling assembly 3 is further included. The rolling assembly 3 is arranged in the installation groove 14, and the rolling assembly 3 is used for transporting the strip-shaped rolled piece.

[0036] In this embodiment, an installation groove 14 is formed on the pallet and a rolling component 3 is arranged, which is a major improvement to the guiding device. This design converts the traditional sliding friction into rolling friction, greatly changing the movement state of the rolled piece on the pallet 1. Compared with sliding friction, the rolling friction significantly reduces the frictional force, making the transportation of the rolled piece smoother and more efficient. This has a remarkable effect on improving production efficiency because the rolled piece can pass through the pallet 1 at a faster speed, reducing the energy loss and transportation delay caused by frictional force.

[0037] Furthermore, the rolling component 3 includes a shaft body 31 and a wheel body 32. The shaft body 31 is arranged in the installation groove 14, and the central axis of the shaft body 31 is perpendicular to the conveying direction of the strip-shaped rolled piece; the wheel body 32 rotates and slides on the shaft body 31, and the sliding direction of the wheel body 32 is the axial direction of the shaft body 31.

[0038] In this embodiment, the structural design of the shaft body 31 and the wheel body 32 of the rolling component 3 is ingenious. The central axis of the shaft body 31 is perpendicular to the conveying direction of the strip-shaped rolled piece, ensuring that the rotation direction of the wheel body 32 perfectly fits the conveying direction of the rolled piece, maximizing the advantage of rolling friction and minimizing the frictional force.

[0039] In addition, the wheel body 32 can slide axially on the shaft body 31, and this characteristic is very important. When the guiding section 22 acts on the strip-shaped rolled piece to adjust its position, the burden on the guiding section 22 may be increased due to frictional force. However, since the wheel body 32 is slidably arranged on the shaft body 31, when the strip-shaped rolled piece moves axially along the shaft body 31, the wheel body 32 serves as a sliding component to promote the movement of the strip-shaped rolled piece, further reducing the force provided by the guiding section 22 when adjusting the position of the strip-shaped rolled piece and further extending the service life of the guiding section 22.

[0040] Furthermore, the rolling component 3 further includes a reset member 33. The reset member 33 acts on the wheel body 32 and is used to provide a reset force for the wheel body 32 after its position changes due to sliding.

[0041] In this embodiment, the existence of the reset member 33 allows the wheel body 32 to gradually return to its initial position under the action of the reset member 33 as the strip-shaped rolled piece is conveyed during the process of the wheel body 32 sliding and assisting the movement and position adjustment of the strip-shaped rolled piece. The whole process is very smooth, enabling the wheel body 32 to continuously play the role of assisting in adjusting the position of the strip-shaped rolled piece.

[0042] Furthermore, the reset member 33 is a spring. The reset member 33 is sleeved on the shaft body 31, and one end of the reset member 33 acts on the wheel body 32.

[0043] In this embodiment, refer to Figure 5As shown, setting the reset member 33 as a spring sleeved on the shaft body 31 and acting on the wheel body at one end is a practical and reliable design. As a mature elastic element, the spring has good elasticity and reset ability. When the wheel body 32 slides during the transportation and position adjustment of the strip-shaped rolled piece, it can quickly and accurately generate elastic force to reset the wheel body 32 to the initial position.

[0044] There is a pressure bearing between the spring and the wheel body 32, which can meet the functional requirements of the smooth rotation of the wheel body 32 while satisfying the sliding of the wheel body 32.

[0045] Furthermore, the wheel body 32 has an annular wheel surface 321, and the diameter of the annular wheel surface 321 gradually decreases from the middle to both sides. The annular wheel surface 321 is the surface of the wheel body 32 for carrying the strip-shaped rolled piece.

[0046] In this embodiment, the annular wheel surface 321 of the wheel body 32 adopts a unique design with a diameter gradually decreasing from the middle to both sides, which can reduce the contact area between the wheel body 32 and the strip-shaped rolled piece, reduce the friction force, and thus reduce the guiding driving force of the guiding section 22 on the strip-shaped rolled piece.

[0047] Furthermore, at least two wheel bodies 32 are arranged on the shaft body 31, and reset members 33 are provided on both sides of the wheel body 32.

[0048] In this embodiment, because the diameter of the annular wheel surface 321 gradually decreases from the middle to both sides, the design of at least two wheel bodies 32 can provide stable support for the strip-shaped rolled piece, prevent the strip-shaped rolled piece from tilting in a certain direction due to uneven force, and improve the overall transportation stability.

[0049] Furthermore, a plurality of mounting grooves 14 are arranged in parallel, and rolling components 3 are provided in each of the plurality of mounting grooves 14. The front straight section 11, the angle adjustment section 12, and the rear straight section 13 all have mounting grooves 14.

[0050] In this embodiment, a plurality of mounting grooves 14 are arranged in parallel and evenly distributed on the front straight section 11, the angle adjustment section 12, and the rear straight section 13 of the pallet 1. Each mounting groove 14 is equipped with a rolling component 3. This layout optimizes the support and transportation performance of the pallet 1 for the rolled piece as a whole. No matter where the rolled piece is on the pallet 1, it can be evenly supported by a plurality of rolling components 3, making the rolled piece in a more stable and reliable state during the entire transportation process. This uniform support structure effectively distributes the weight and pressure of the rolled piece to a plurality of rolling components 3, making it easier for the guiding section 22 to assist the strip-shaped rolled piece in position adjustment under the action of the axial sliding of the wheel body 32.

[0051] Further, the guiding section 22 has an opening, and further includes wear-resistant guiding blocks 4. The wear-resistant guiding blocks 4 are slidably arranged in the opening. The opposite sides of the two wear-resistant guiding blocks 4 are wear-resistant guiding surfaces 41. The two wear-resistant guiding blocks 4 are used to slide a corresponding distance in the direction of approaching each other after wear to meet the guiding requirements of the strip-shaped rolled piece.

[0052] In this embodiment, as shown in Figure 1 the wear-resistant guiding blocks 4 of the guiding section 22 can slide in the opening and move in the direction of approaching each other after wear. This design fully considers the long-term operation and accuracy maintenance of the guide device. In actual production, the wear-resistant guiding blocks 4, as the components directly contacting the rolled piece and guiding its direction, will inevitably be worn due to long-term friction. As the wear intensifies, the distance between the wear-resistant guiding blocks 4 will gradually increase, which will have a negative impact on the guiding accuracy of the rolled piece, may cause position deviation of the rolled piece when entering the finishing mill, and further affect the product quality.

[0053] The slidable wear-resistant guiding blocks 4 can automatically adjust the distance after wear to ensure that accurate guiding is always provided for the rolled piece. This design extends the overall service life of the guide device because it reduces the situation of frequent component replacement due to the wear of the wear-resistant guiding blocks 4, reduces the downtime and maintenance costs. At the same time, since the wear-resistant guiding blocks 4 can continuously and accurately guide the rolled piece, it avoids the additional friction loss of the rolled piece due to the decrease in guiding accuracy, keeps the acting force between the rolled piece and the guiding section 22 within a reasonable range, ensures that the rolled piece can enter the finishing mill at an accurate position and attitude, and ensures the long-term stability and consistency of the product quality, providing a solid guarantee for continuous and stable high-quality production.

[0054] Guiding rollers are rotatably arranged on one side opposite to the guiding section 22 or on the wear-resistant guiding surface 41. On the one hand, the guiding rollers can realize the conveying of the strip-shaped rolled piece in the advancing direction; on the other hand, the guiding rollers can provide a force for adjusting the position of the strip-shaped rolled piece. With the various settings in the above text, the wear of the guiding rollers by the strip-shaped rolled piece can also be reduced, and the service life and stability can be improved.

[0055] A guiding method includes the following steps: S1: Before one end of the strip-shaped rolled piece enters the angle adjustment section 12 and the rear straight section 13 in sequence, adjust the angle adjustment section 12 to be in an inclined state; S2: During the process of conveying one end of the strip-shaped rolled piece into the angle adjustment section 12 and the rear straight section 13 in sequence, the guiding section (22) adjusts the guiding position of the strip-shaped rolled piece; S3: After one end of the strip-shaped rolled piece passes through the angle adjustment section 12 and the rear straight section 13, adjust the angle adjustment section 12 to be in a horizontal state so that the angle adjustment section 12, the front straight section 11, and the rear straight section 13 are in the same plane.

[0056] In this embodiment, before one end of the strip-shaped rolled piece enters, the angle adjustment section 12 is in an inclined state, which can make the angle adjustment section 12 form a certain angle with the rear straight section 13. When the strip-shaped rolled piece passes through the angle adjustment section 12 and continues to be conveyed, under the action of gravity, the strip-shaped rolled piece bends and continues to be conveyed on the rear straight section 13. Then, the bending will generate an elastic force, which offsets a part of the gravity. The pressure of the strip-shaped rolled piece on the rear straight section 13 decreases, the friction decreases, the acting force of the guiding section 22 on the strip-shaped rolled piece decreases, and the wear of the guiding section 22 decreases, thus improving the service life.

[0057] After the guiding function is completed, the angle adjustment section 12, the front straight section 11 and the rear straight section 13 are on the same plane, further improving the subsequent conveying stability and smoothness of the strip-shaped rolled piece.

[0058] Preferably, in S1, the inclination angle of the angle adjustment section 12 is adjusted according to the thickness, weight and elastic coefficient of the conveyed strip-shaped rolled piece.

[0059] In this embodiment, the inclination angle of the angle adjustment section 12 is adjustable. The appropriate inclination angle can be determined according to the information of the strip-shaped rolled piece, and the friction on the rear straight section 13 can be reduced while ensuring stability.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
