The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] As shown in Figs. 1-3 , the present application relates to a multi-mode strip head buckling prevention device. As shown in Fig. 1 , the multi-mode strip head buckling prevention device comprises a base 10; the base 10 refers to the installation basis of the entire device, and the entire head buckling prevention device is firmly fixed on the roller foundation or equipment base 10 of the production line through anchor bolts or other connection methods; which ensures the stability of the device when it is subjected to strip impact and vibration, and is the cornerstone of safe and reliable operation of the entire equipment.

[0023] A frame body 20 is connected to the top of the base 10; the frame body 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 type frame; which can provide installation positions and supports for the guide 30 and the head buckling prevention adjusting assembly 40, and determine the height and span of these functional components in space.

[0024] A guide 30 is arranged between the base 10 and the frame body 20 in the rolling direction; the guide 30 refers to the guiding and guarding device of the strip, which is arranged between the base 10 and the frame body 20 in the rolling direction (i.e. the direction of the strip advancing). It can ensure that the strip, especially its head, can be accurately centered and smoothly enter the next rolling mill or equipment to prevent deviation; at the same time, it can physically constrain the transverse movement of the strip.

[0025] The anti-camming adjustment assembly 40 is obliquely arranged in the frame body 20 and is located directly above the strip; the anti-camming adjustment assembly 40 is directly responsible for pressing down the cammed head of the strip, is obliquely arranged in the frame body 20, is installed on the frame body 20 at a certain angle with the horizontal plane, and is located directly above the strip, thereby being capable of providing guarantee for delicate pressing down.

[0026] The anti-camming adjustment assembly 40 is obliquely arranged in the frame body 20 and is located directly above the strip; the anti-camming adjustment assembly 40 is directly responsible for pressing down the cammed head of the strip, is obliquely arranged in the frame body 20, is installed on the frame body 20 at a certain angle with the horizontal plane, and is located directly above the strip, thereby being capable of providing guarantee for delicate pressing down.

[0027] The anti-camming adjustment assembly 40 is obliquely arranged in the frame body 20 and is located directly above the strip; the anti-camming adjustment assembly 40 is directly responsible for pressing down the cammed head of the strip, is obliquely arranged in the frame body 20, is installed on the frame body 20 at a certain angle with the horizontal plane, and is located directly above the strip, thereby being capable of providing guarantee for delicate pressing down.

[0028] The anti-camming adjustment assembly 40 is obliquely arranged in the frame body 20 and is located directly above the strip; the anti-camming adjustment assembly 40 is directly responsible for pressing down the cammed head of the strip, is obliquely arranged in the frame body 20, is installed on the frame body 20 at a certain angle with the horizontal plane, and is located directly above the strip, thereby being capable of providing guarantee for delicate pressing down.

[0029] From the above description, it can be seen that the present application achieves the following technical effects: In the embodiment of the present application, the anti-camming adjustment assembly 40 is arranged at a specified position above the strip, and one end of the anti-camming adjustment assembly 40 acts on the head of the strip to press down the position of the head of the strip, thereby achieving the purpose of pressing down the cammed head of the strip, realizing normal production of the strip, improving the yield of finished products, and avoiding damage to the equipment, thereby solving the technical problem that, in the current hot continuous rolling process, the head of the strip is often cammed due to factors such as temperature gradient and rolling force change, thereby causing the strip to be jammed or folded at the head of the strip to form a defective coil, which not only seriously affects the smooth progress of production, but also increases the amount of cut-off strip, reduces the yield of the strip, and, in severe cases, the cammed head of the strip can hit the rolling line equipment, causing the strip to be stacked, the equipment to be damaged, and other major accidents.

[0030] Further, the anti-camming adjustment assembly 40 comprises a first driving component connected to the top of the frame body 20, the first driving component is connected to a transmission component, the output end of the transmission component is provided with a transmission plate, the two ends of the transmission plate are oppositely provided with a first wire bundle and a second wire bundle, one end of a pressing plate 401 is connected to the first wire bundle through a variable-diameter rotating shaft arranged on the frame body 20, and the other end of the pressing plate 401 is connected to the second wire bundle; The variable-diameter rotating shaft is arranged on the first wire bundle to form a height difference between the two ends of the pressing plate 401.

[0031] Specifically, the first driving component can be a servo motor or a speed reducer, which is installed at the top of the frame body 20 as a power source; the transmission component can be a lead screw or a connecting rod, which converts the rotary 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 lines can be steel wires or chains, and the two ends of the transmission plate are connected to the two lines; the variable-diameter rotating shaft is a key component, which is installed on the frame body 20 and has a variable radius (or a non-circular shape); the lower pressing plate 401 directly acts on the work component of the strip.

[0032] It should be noted that when the first driving component is actuated, the transmission plate is pulled; the transmission plate pulls the first and second lines; because the first line passes around the variable-diameter rotating shaft, while the second line is directly connected, the actual effective length change rate of the first line is different from that of the second line.

[0033] This difference causes one end of the lower pressing plate 401 to be lifted or lowered at a different amplitude than the other end, thereby automatically forming an inclination angle (i.e., a height difference), and achieving automatic and synchronous adjustment of the inclination angle of the lower pressing plate 401 with a single drive.

[0034] Further, the base 10 is also provided with a strip position detection sensor, and the detection path of the strip position detection sensor is located on the feeding route of the strip. It can be understood that the strip position detection sensor can be an optical sensor or a laser range finder, which is installed on the base 10 to monitor the position and lifting height of the head of the strip in real time, and can achieve precise detection effect.

[0035] Further, the frame body 20 is also provided with an electric control box, and the electric control box is electrically connected with the first driving component and the strip position detection sensor respectively; When the strip position detection sensor feeds back the detected position signal to the electric control box, the electric control box sends a first control instruction to control the first driving component to act, so that the anti-lifting head adjusting assembly 40 inclines to act on the strip. It can be understood that good electrical connection effect can be achieved, thereby providing guarantee for subsequent precise cooperative control.

[0036] Further, the base 10 is also provided with a sliding assembly 50 on both sides along the feeding direction of the strip, and the sliding assembly 50 comprises a sliding block 501 provided on the base 10, and the sliding block 501 is in sliding connection with a sliding rail 502. It can be understood that the sliding assembly 50 is composed of the sliding block 501 and the sliding rail 502, which are installed on both sides of the base 10, and can make the whole device move along the rolling direction.

[0037] Further, one side of the frame 20 is connected with the second driving component 70 along the strip feeding direction through the connecting component 60, and the second driving component 70 is electrically connected with the electric control box; When the electric control box receives a preset operation signal, a second control instruction is sent to control the second driving component 70 to act, so that the device has a rolling state and a cleaning state. It can be understood that the second driving 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] As shown in Figs. 2-3 The two sides of the base 10 along the strip feeding direction are respectively provided with locking components 80, and the locking components 80 are electrically connected with the electric control box. When the device is in the rolling state, the electric control box sends a third control instruction to control the locking components 80 to lock the two sides of the base 10, so that the device is fixed at a first preset position. When the device is in the cleaning state, the electric control box sequentially sends a second control instruction and a third control instruction to control the locking components 80 to release the base 10 and control the second driving component 70 to drive the device to move to a second preset position along the slide rail 502. It can be understood that the locking component 80 can be a hydraulic pin or a mechanical clamp, which can lock the base 10 on the slide rail 502 when the device needs to be fixed, so as to prevent the base 10 from moving.

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

[0040] When rolling is needed, the push plate connected with the hydraulic cylinder pushes the entire module along the slide rail 502 to the fixed position. After the locking cylinder is locked, the hydraulic cylinder is retracted by a small stroke, and only the chain is flexibly connected with the module.

[0041] In the cleaning state, when the roller needs to be replaced, an accident needs to be handled, or maintenance needs to be performed, the electric control box controls the locking component 80 to release, and the second driving component 70 acts to move the entire device to the second preset position (non-working position) along the slide rail 502, so as to leave a spacious space for the production line, greatly improving the convenience and safety.

[0042] When the steel needs to be withdrawn and cleaned after stacking, 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] Further, the lower pressing plate 401 is arranged obliquely along the strip steel feeding direction, so that the low end of the oblique end of the lower pressing plate 401 acts on the end close to the strip steel head. It can be understood that the oblique arrangement direction is that the lower pressing plate 401 is inclined along the strip steel feeding direction, and the low end of the oblique end is close to the strip steel head, which conforms to the dynamic process of the strip steel advancing, and the low end can first contact the raised head to achieve smoother and more effective guiding and pressing.

[0044] Further, the low end of the oblique end of the lower pressing plate 401 is reserved a distance from the end face of the strip steel head. It can be understood that it is ensured that the lower pressing plate 401 will never contact the strip steel surface when the strip steel head is not raised, completely avoiding the risk of scratching the product, and only acting when the raised head is detected to be excessive.

[0045] Further, the width of the lower pressing plate 401 is not less than the width of the strip steel. It can be understood that good pressing effect can be ensured.

[0046] The application also has the following beneficial effects: 1. Effectively prevent the raised head accident, protect the production safety and continuity, and the serious raised head of the strip steel is one of the major accidents of the rolling line; the raised strip steel can hit the upper equipment, cause damage to the equipment, even tear the strip steel, and cause non-planned shutdown of the production line; the device can actively intervene to kill the accident in the embryonic state, greatly reduce the risk of equipment damage and downtime, and protect the continuity and safety of production.

[0047] 2. Improve product quality and yield, and avoid surface damage: if there is no anti-raised head device, the raised strip steel will have a hard collision and scraping with the upper equipment, causing scratches, indentations and other defects on the surface of the strip steel; the device guides the strip steel by a controllable and relatively flexible method (inclined surface contact), avoids rigid impact, and effectively protects the surface quality of the strip steel.

[0048] 3. Ensure smooth biting, and the head of the strip steel must be kept flat to be smoothly “bitten” by the rollers of the next rolling mill; the device ensures that the head shape is good, avoids quality problems such as steel stacking and folding caused by biting failure, and improves the first pass rate and yield of the product.

[0049] 4. Simple and reliable structure, easy maintenance, modular design, the device is composed of modules such as base, frame, guide, adjusting assembly, etc., and the structure is clear, easy to manufacture, install and maintain.

[0050] 5. Work with the guide system, and the functions are complementary, the device integrates the horizontal guide (guide) and the vertical anti-raising (adjusting assembly) functions; the guide is responsible for controlling the transverse position of the strip steel, and the anti-raising component is responsible for controlling the vertical position, and the two work together to realize the three-dimensional accurate control of the running track of the strip steel, and the effect is better than that of the single-function device.

[0051] The preferred embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the specific details of the above-described embodiments. Various equivalent changes can be made to the technical solutions of the present application within the technical concept of the present application, and these equivalent changes all belong to the protection scope of the present application.
