Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, and in particular to a multi-mode strip anti-tilting device. Background Technology

[0002] In recent years, my country's steel product market has undergone significant changes. Among them, the hot-rolled strip steel market, especially the medium and narrow strip steel market, has been exceptionally hot, and the demand for medium and narrow strip steel has also surged.

[0003] Currently, during hot strip rolling production, the strip head often warps due to factors such as temperature gradients and changes in rolling force. This can lead to strip jamming or folding at the strip head, forming defective coils. This not only severely impacts production but also increases the amount of strip cut, reduces strip yield, and, in severe cases, can cause serious accidents such as steel pile-up and equipment damage when the strip warps impact the rolling mill. Currently, no effective solution has been proposed to address these problems. Utility Model Content

[0004] Purpose of the utility model: To provide a multi-mode strip anti-tilting device to at least solve one of the problems existing in the prior art.

[0005] Technical solution: A multi-mode strip anti-tilting device, comprising: Base; The frame is connected to the top of the base; Guides are disposed between the base and the frame along the rolling direction; and The anti-tilting adjustment component is obliquely installed inside the frame and located directly above the strip steel; The anti-tilting adjustment component is preset at a designated position above the strip, so that one end of it is angled and acts on the head of the strip that is tilting, so as to lower the position of the strip head.

[0006] Preferably, the anti-tilting adjustment assembly includes: a first driving component connected to the top of the frame, the first driving component being connected to a transmission component, a transmission plate being provided at the output end of the transmission component, a first wire harness and a second wire harness being provided opposite to each other at both ends of the transmission plate, the first wire harness being connected to one end of the lower pressure plate via a variable diameter rotating shaft provided on the frame, and the second wire harness being connected to the other end of the lower pressure plate. The variable diameter shaft is provided on the first wire harness to create a height difference between the two ends of the lower pressure plate.

[0007] Preferably, the base is also provided with a strip position detection sensor, and the detection path of the strip position detection sensor is located on the feed path of the strip.

[0008] Preferably, the frame is also provided with an electrical control box, which is electrically connected to the first drive component and the strip position detection sensor respectively; When the strip position detection sensor feeds back the detected position signal to the electrical control box, the electrical control box issues a first control command based on the received detection signal to control the first drive component to operate, so that the anti-tilting adjustment component tilts onto the strip.

[0009] Preferably, sliding components are provided on both sides of the base along the strip feeding direction. The sliding components include a slider disposed on the base and the slider is slidably connected to the slide rail.

[0010] Preferably, one side of the frame is connected to the second drive component along the strip feeding direction via a connector, and the second drive component is electrically connected to the electrical control box; When the electrical control box receives a preset operation signal, it issues a second control command to control the second drive component to operate, so that the device has a rolling state and a clearing state.

[0011] Preferably, locking components are provided on both sides of the base along the strip feeding direction, and the locking components are electrically connected to the electrical control box; During the rolling process, the electrical control box issues a third control command to control the locking component to lock both sides of the base, so that the device is limited and fixed in the first preset position. In the clearing state, the electrical control box sequentially issues a second control command and a third control command to control the locking component to release the base, and controls the second drive component to move along the slide rail to the second preset position.

[0012] Preferably, the lower pressure plate is obliquely arranged along the strip feeding direction so that the lower pressure plate's inclined end acts on the end near the strip head.

[0013] Preferably, a gap is reserved between the lowest point of the inclined end of the lower pressure plate and the end face of the strip head.

[0014] Preferably, the width of the lower pressure plate is not less than the width of the strip steel.

[0015] Beneficial Effects: In this embodiment, an anti-tilting component is added. By pre-setting the anti-tilting adjustment component at a designated position above the strip, one end of the component acts on the head of the strip that is tilting, thereby lowering the head position and achieving the purpose of reducing the tilting of the strip. This achieves the technical effects of normal strip production, improved yield, and avoidance of equipment damage. Furthermore, it solves the technical problem that in the current hot continuous rolling process, the strip head often tilts due to factors such as temperature gradient and rolling force changes, resulting in steel jamming or folding at the strip head to form defective coils. This not only seriously affects the smooth progress of production but also increases the amount of strip cut, reduces the strip yield, and, in severe cases, can collide with the rolling line equipment, leading to major accidents such as steel piling and equipment damage.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-3 As shown, this application relates to a multi-mode strip anti-tilting device. For example... Figure 1 As shown, the multi-mode strip anti-tilting device includes: a base 10; the base 10 refers to the installation foundation of the entire device, which is firmly fixed to the roller foundation or equipment base 10 of the production line by anchor bolts or other connection methods; it ensures the stability of the device when subjected to strip impact and vibration, and is the cornerstone of the safe and reliable operation of the entire set of equipment.

[0023] The frame 20 is connected to the top of the base 10; the frame 20 refers to the support structure of the device, which is connected to the top of the base 10 to form a portal or bridge frame; it provides installation position and support for the guide 30 and the anti-tilting adjustment assembly 40, and determines the height and span of these functional components in space.

[0024] A guide 30 is positioned between the base 10 and the frame 20 along the rolling direction. The guide 30 is a device for guiding and protecting the strip steel, positioned between the base 10 and the frame 20 along the rolling direction (i.e., the direction in which the strip steel moves). It ensures that the strip steel, especially its head, can be accurately centered and smoothly enter the next rolling mill or equipment, preventing deviation; simultaneously, it physically restrains the lateral movement of the strip steel.

[0025] The anti-tilting adjustment component 40 is obliquely installed inside the frame 20 and located directly above the strip steel. The anti-tilting adjustment component 40 is directly responsible for pressing down the tilted head of the strip steel. It is obliquely installed inside the frame 20 and installed on the frame 20 at a certain angle to the horizontal plane, and located directly above the strip steel, which can provide a guarantee for precise downward pressing.

[0026] The anti-tilting adjustment component 40 is pre-positioned at a designated location above the strip, with one end angled to act on the head of the strip that is tilting upwards, thereby pressing down the head of the strip. This achieves a good limiting and pressing effect on the head of the strip, thus ensuring good strip passage performance.

[0027] This application adopts a box-type retractable strip steel anti-tilting device to replace the original export guide 30 and anti-tilting device, thus combining the functions of guide 30 and anti-tilting.

[0028] To address the problem of steel billet stacking caused by billet warping during the rolling process, this application provides a novel modular removable strip anti-warping device. This device reduces potential damage to the insulation cover caused by billet impact during rolling, facilitates handling of strip stacking issues, and increases equipment safety and stability.

[0029] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, an anti-tilting component is added. By pre-setting the anti-tilting adjustment component 40 at a designated position above the strip, one end of which acts obliquely on the head of the strip that is tilting, the position of the strip head is lowered, thereby achieving the purpose of lowering the tilting of the strip. This achieves the technical effects of normal strip production, improved yield, and avoidance of equipment damage. It also solves the technical problem that in the current hot continuous rolling process, the strip head often tilts due to factors such as temperature gradient and rolling force changes, which leads to steel jamming or folding at the strip head to form defective coils. This not only seriously affects the smooth progress of production, but also increases the amount of strip cut, reduces the strip yield, and, in severe cases, can collide with the rolling line equipment, leading to major accidents such as steel piling and equipment damage.

[0030] Furthermore, the anti-tilting adjustment assembly 40 includes: a first driving component connected to the top of the frame 20, the first driving component being connected to a transmission component, a transmission plate being provided at the output end of the transmission component, a first wire harness and a second wire harness being provided opposite to each other at both ends of the transmission plate, the first wire harness being connected to one end of the lower pressure plate 401 via a variable diameter rotating shaft provided on the frame 20, and the second wire harness being connected to the other end of the lower pressure plate 401; The variable diameter shaft is provided on the first wire harness to create a height difference between the two ends of the lower pressure plate 401.

[0031] Specifically, the first drive component can be a servo motor or a reducer, which serves as a power source and is installed on the top of the frame 20; the transmission component can be a lead screw or a connecting rod, which converts the rotational motion of the motor into linear motion; the transmission plate is connected to the transmission component and moves linearly with it; the first and second wire harnesses can be steel wire ropes or chains, and the two ends of the transmission plate are respectively connected to these two ropes; the variable diameter shaft is a key component, installed on the frame 20, and its radius is variable (or non-circular); the lower pressure plate 401 directly acts on the working part of the strip steel.

[0032] It should be noted that when the first drive component is activated, the transmission plate is pulled; the transmission plate pulls the first and second wire harnesses; since the first wire harness bypasses the variable diameter shaft, while the second wire harness is directly connected, the actual effective length change rate of the first wire harness is different from that of the second wire harness.

[0033] This difference causes one end of the lower pressure plate 401 to be raised or lowered by a different amount than the other end, thus automatically forming a tilt angle (i.e., height difference), and the tilt angle of the lower pressure plate 401 is automatically and synchronously adjusted by a single drive.

[0034] Furthermore, a strip position detection sensor is also provided on the base 10, and the detection path of the strip position detection sensor is located on the feed path of the strip. It can be understood that the strip position detection sensor can be a photoelectric sensor or a laser rangefinder. By installing it on the base 10, the position and tilting height of the strip head can be monitored in real time, achieving a precise detection effect.

[0035] Furthermore, an electrical control box is also provided on the frame 20, and the electrical control box is electrically connected to the first drive component and the strip position detection sensor respectively; Specifically, when the strip position detection sensor feeds back the detected position signal to the electrical control box, the electrical control box issues a first control command based on the received detection signal to control the first driving component to operate, so that the anti-tilting adjustment component 40 tilts onto the strip. This achieves a good electrical connection, thus ensuring precise subsequent coordinated control.

[0036] Furthermore, sliding components 50 are respectively provided on both sides of the base 10 along the strip feeding direction. Each sliding component 50 includes a slider 501 disposed on the base 10, and the slider 501 is slidably connected to a slide rail 502. It can be understood that the sliding component 50, composed of the slider 501 and the slide rail 502, is installed on both sides of the base 10, enabling the entire device to move along the rolling direction.

[0037] Furthermore, one side of the frame 20 is connected to the second drive component 70 via a connector 60 along the strip feed direction, and the second drive component 70 is electrically connected to the electrical control box; When the electrical control box receives a preset operation signal, it issues a second control command to control the second drive component 70 to operate, so that the device has a rolling state and a clearing state. It can be understood that the second drive component 70 can be a hydraulic cylinder or a motor, which can provide power to push or pull the entire device to move on the slide rail 502.

[0038] like Figure 2-3 As shown, locking components 80 are respectively provided on both sides of the base 10 along the strip feeding direction, and the locking components 80 are electrically connected to the electrical control box; During the rolling process, the electrical control box issues a third control command to control the locking component 80 to lock both sides of the base 10, so that the device is limited and fixed in the first preset position. During the clearing state, the electrical control box sequentially issues second and third control commands to control the locking component 80 to release the base 10, and controls the second drive component 70 to drive the device to move directionally along the slide rail 502 to the second preset position. It is understood that the locking component 80 can be a hydraulic pin or a mechanical clamp, which locks the base 10 onto the slide rail 502 to prevent movement when a fixing device is needed.

[0039] Specifically, in the rolling state, the device is located in the first preset position (working position), the locking component 80 is locked, and the lower pressure plate 401 is located above the strip steel in preparation for operation.

[0040] When rolling is required, the push plate connected to the front of the hydraulic cylinder pushes the entire module along the slide rail 502 to a fixed position. After the locking cylinder locks, the hydraulic cylinder retracts a small stroke, and the module is flexibly connected only by the chain.

[0041] In the clearing state, when it is necessary to replace the rolls, handle accidents, or perform maintenance, the electrical control box controls the locking component 80 to release, and the second drive component 70 to move the entire device along the slide rail 502 to the second preset position (non-working position), leaving ample space for the production line and greatly improving convenience and safety.

[0042] When the steel is piled up and needs to be removed for cleaning, the stacked part is cut open by flame cutting, and then the entire module is pulled out along the slide rail 502 by the hydraulic cylinder, and the chain is straightened.

[0043] Furthermore, the lower pressure plate 401 is obliquely arranged along the strip feed direction so that the lowest point of the inclined end of the lower pressure plate 401 acts on the end closest to the head of the strip. It can be understood that the oblique arrangement, with the lower pressure plate 401 inclined along the strip feed direction and its lowest point close to the head of the strip, conforms to the dynamic process of the strip's forward movement. The lowest point can contact the raised head first, achieving smoother and more effective guidance and pressing.

[0044] Furthermore, the lower pressure plate 401 has a pre-reserved gap between its inclined end and the head end face of the strip. This ensures that the lower pressure plate 401 will never contact the strip surface when the strip is not warped, completely avoiding the risk of scratching the product. It only activates when excessive warping is detected.

[0045] Furthermore, the width of the pressure plate 401 is not less than the width of the strip. This ensures a good pressing effect.

[0046] This application also has the following beneficial effects: 1. Effectively prevents strip tip lifting accidents, ensuring production safety and continuity. Severe strip tip lifting is one of the major accidents on the rolling line. The lifted strip may collide with the equipment above, causing equipment damage or even tearing the strip, resulting in unplanned shutdown of the production line. This device can actively intervene and nip accidents in the bud, greatly reducing the risk of equipment damage and downtime, and ensuring the continuity and safety of production.

[0047] 2. Improve product quality and yield, and avoid surface damage: Without an anti-tilting device, the tilted strip will collide and scrape against the equipment above, causing defects such as scratches and indentations on the strip surface; this device guides the strip in a controllable and relatively flexible manner (inclined surface contact), avoiding rigid impact and effectively protecting the surface quality of the strip.

[0048] 3. To ensure smooth bite, the strip head must remain straight so that it can be smoothly "bitten" by the rolls of the next rolling mill. This device ensures a good head shape and avoids quality problems such as steel piling and folding caused by bite failure, thereby improving the first pass rate and yield of the product.

[0049] 4. The structure is simple and reliable, and maintenance is convenient. The modular design consists of modules such as base, frame, guide, and adjustment components. The structure is clear and easy to manufacture, install and maintain.

[0050] 5. Working in conjunction with the guide system, the device integrates horizontal guidance (guide) and vertical anti-tilting (adjustment component) functions into one unit; the guide is responsible for controlling the lateral position of the strip, while the anti-tilting component is responsible for controlling the vertical position. The two work together to achieve three-dimensional and precise control of the strip's running trajectory, which is superior to single-function devices.

However, the present invention is not limited to the specific details of the above embodiments.
