Description

Technical Field

[0001] This utility model relates to the field of seamless tube processing technology, and in particular to an online monitoring and fault early warning device for the rolling ring during seamless tube processing. Background Technology

[0002] In the seamless pipe processing process, the online monitoring and fault early warning equipment for the rolling ring is an automated equipment system used to monitor the working status of the rolling ring in real time, detect abnormalities in a timely manner, and issue early warnings.

[0003] Existing online monitoring and fault early warning equipment uses a variety of sensors and data analysis technologies to ensure that the rolling rings operate stably in high-load, high-precision processing environments, avoiding production interruptions or product quality defects due to equipment failure.

[0004] However, during the processing of seamless tubes, the processing equipment generates metal debris. This metal debris may adhere to the surface of the rolling roller and accumulate in the sensor monitoring area, which may cause the detection signal to be blocked or scattered, leading to misjudgment of wear depth and distortion of monitoring data, which is not conducive to improving the accuracy of monitoring.

[0005] Therefore, this application provides an online monitoring and fault early warning device for the rolling ring during seamless pipe processing to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an online monitoring and fault early warning device for the rolling ring during seamless pipe processing.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an online monitoring and fault early warning device for the rolling ring during seamless tube processing, comprising a Pilger mill and rolling rolls, wherein the rolling rolls are disposed on the inner side of the Pilger mill, and further comprising:

[0008] Wear monitoring component, the wear monitoring component is placed inside the Pilger mill, the rolling mill includes a support plate set on the side of the rolling mill near the rolling mill, the number of support plates set on the Pilger mill is two, a wear sensor is fixedly connected to the top of the support plate, and a cleaning plate is fixedly connected to the side of the support plate near the rolling mill.

[0009] A sliding assembly is placed on top of the wear monitoring assembly and is used to drive the support plate to move with the rolling mill. The sliding assembly includes a connecting rod fixed to the top of the support plate. A push plate is fixedly connected to the side of the Pilger mill near the connecting rod, and the push plate is engaged with the connecting rod.

[0010] Furthermore, the cleaning plate has an arc-shaped structure, and the side of the cleaning plate near the rolling roller has a rounded corner structure.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: avoiding the situation where the cleaning plate and the rolling roller are mismatched, which may cause them to jam or increase wear, and improving the stability of the cleaning plate during use.

[0012] Furthermore, the width of the cleaning plate is smaller than the width of the rolling roller, and the width of the cleaning plate on one side is greater than the width of the cleaning plate on the other side.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by adapting the two cleaning plates to the gradient rolling groove, differentiated monitoring of wear characteristics in different areas can be carried out, thereby improving the accuracy of detection.

[0014] Furthermore, the cleaning plate is provided with bristles on the side near the roller.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the bristles are set in a threaded structure, so that the bent bristles are elastic. When the bristles come into contact with the surface of the roller, the elasticity of the bristles buffers the contact pressure between the cleaning plate and the roller, reducing rigid wear.

[0016] Furthermore, a warning light is fixedly connected to the side of the support plate near the wear sensor.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the wear sensor transmits a signal to the warning light through the data line, activates the warning light, and the warning light flashes to indicate that the wear of the roller exceeds the standard and needs to be stopped for replacement.

[0018] Furthermore, both ends of the connecting rod are fixedly connected to sliders, and the connecting rod is slidably connected to the Pilger mill through the sliders.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the sliding block and the sliding groove cooperate to limit the movement path of the connecting rod, which helps to improve the stability of the connecting rod during movement.

[0020] Furthermore, a telescopic rod is fixedly connected between the Pilger mill and the slide block, and a return spring is sleeved on the telescopic rod. The return spring is fixedly connected to the Pilger mill and the slide block.

[0021] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the support plates on both sides always move stably with the rolling roller, and ensures that the wear sensor remains in contact with the rolling roller.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up a wear monitoring component and installing a cleaning plate on the support plate, when the rolling roller rotates and moves, the cleaning plate will contact the rolling groove on the rolling roller, thereby removing the metal impurities that adhere to the rolling roller during the rolling of the seamless tube. The rolling roller continues to rotate, moving the cleaned surface to the bottom of the wear sensor. The wear degree is judged by monitoring the pressure change on the surface of the rolling roller. Since the rolling roller needs to make continuous back-and-forth movements when rolling the seamless tube, the support plate is set on both sides of the rolling roller, which can monitor both sides in real time. This ensures that the monitoring area covers the entire circumference of the rolling roller, avoids the blind spots that exist in static detection, and makes the wear sensor suitable for scenarios that require continuous rotation and rolling, which is conducive to improving monitoring accuracy.

[0024] 2. By setting up a sliding component, after installing a C-shaped pusher plate on the roll support of the Pilger mill, when the roll support drives the rolling roll to move, the rolling roll pushes the connecting rod through the pusher plate, and the connecting rod drives the support plate to move synchronously with the rolling roll. This design ensures that the wear sensor on the support plate is always in contact with the rolling roll, thereby realizing the real-time monitoring of the rolling roll by the wear sensor and ensuring that wear data is continuously acquired during the movement of the rolling roll.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this utility model provides a technical solution: an online monitoring and fault early warning device for the rolling ring during seamless pipe processing, including a Pilger mill 1 and a rolling roll 2. The rolling roll 2 is located inside the Pilger mill 1. The Pilger mill 1 also includes a sensor system, a data acquisition and processing system, and an early warning and control system. The sensor system includes vibration sensors, temperature sensors, position sensors, and a visual monitoring module, used to monitor the working and material status of the rolling roll 2 in real time. The data acquisition and processing system collects data from each sensor, performs preprocessing such as filtering and noise reduction, and transmits it to the central control system via wired or wireless means. The early warning and control system ensures that when the data exceeds a safety threshold or an abnormal mode occurs, the operator is notified via audible and visual alarms, SMS, email, etc.

[0036] like Figures 1-3 As shown, the wear monitoring component 3 is placed inside the Pilger mill 1. The rolling mill 2 includes a support plate 31 on the side of the rolling mill 1 near the rolling mill 2. There are two support plates 31 on the Pilger mill 1. A wear sensor 32 is fixedly connected to the top of the support plate 31. A cleaning plate 33 is fixedly connected to the side of the support plate 31 near the rolling mill 2.

[0037] like Figures 1-4As shown, the sliding component 4 is placed on top of the wear monitoring component 3 and is used to drive the support plate 31 to move with the rolling roller 2. The sliding component 4 includes a connecting rod 41 fixed to the top of the support plate 31. A push plate 42 is fixedly connected to the side of the Pilger mill 1 near the connecting rod 41. The push plate 42 is engaged with the connecting rod 41. By installing a cleaning plate 33 on the support plate 31, when the rolling roller 2 rotates and moves, the cleaning plate 33 contacts the rolling groove on the rolling roller 2, removing the metal impurities adhering to the rolling roller 2 during the rolling of the seamless tube. The rolling roller 2 continues to rotate, moving the cleaned surface to the bottom of the wear sensor 32. The wear sensor 32 is a MIK-P300 pressure sensor. The wear sensor 32 continuously contacts the rolling roller 2, monitors the pressure change on the surface of the rolling roller 2, and judges the degree of wear of the rolling roller 2. During the process, continuous back-and-forth movement is required. The support plate 31 is set on both sides of the rolling roller 2 to monitor both sides of the rolling roller 2 in real time, ensuring that the monitoring area covers the entire circumference of the rolling roller 2, avoiding blind spots in static detection, and making the wear sensor 32 suitable for scenarios requiring continuous rotation and rolling. This solves the problem that metal debris may adhere to the surface of the rolling roller 2, leading to misjudgment of wear depth and distortion of monitoring data, which is beneficial to improving the accuracy of monitoring. Furthermore, by installing a C-shaped push plate 42 on the roll support of the Pilger mill 1, when the roll support moves the rolling roller 2, the rolling roller 2 pushes the connecting rod 41 through the push plate 42. The connecting rod 41 drives the support plate 31 to move with the rolling roller 2, so that the wear sensor 32 on the support plate 31 always keeps in contact with the rolling roller 2, thereby realizing real-time monitoring of the rolling roller 2 by the wear sensor 32 and ensuring monitoring of the rolling roller 2 in the moving state.

[0038] Furthermore, such as Figure 3 As shown, the cleaning plate 33 has an arc-shaped structure, and the side of the cleaning plate 33 near the rolling roller 2 has a rounded corner structure. By setting the arc-shaped surface of the cleaning plate 33 to a rounded corner structure, the arc surface of the cleaning plate 33 is adapted to the arc surface of the rolling groove on the rolling roller 2, so that the contact between the cleaning plate 33 and the rolling roller 2 is smoother, avoiding the situation where the cleaning plate 33 and the rolling roller 2 are mismatched, which may cause them to jam or increase wear. This is beneficial to improving the stability of the cleaning plate 33 during use.

[0039] Furthermore, such as Figure 3 As shown, the width of the cleaning plate 33 is smaller than the width of the rolling roller 2, and the width of the cleaning plate 33 on one side is larger than the width of the cleaning plate 33 on the other side. Since the structure of the rolling groove on the rolling roller 2 is gradually deformed, the diameter of one side of the rolling groove is larger than the diameter of the other side. By setting the two cleaning plates 33 with different widths, the two cleaning plates 33 can be adapted to the gradually deformed rolling groove, which can perform differentiated monitoring of wear characteristics in different areas and improve the accuracy of detection.

[0040] Furthermore, such as Figure 3 As shown, the cleaning plate 33 is provided with bristles 34 on the side near the roller 2. By setting the bristles 34 in a threaded structure, the bent bristles 34 are elastic. When the bristles 34 come into contact with the surface of the roller 2, the elasticity of the bristles 34 buffers the contact pressure between the cleaning plate 33 and the roller 2, reducing rigid wear.

[0041] Furthermore, such as Figure 3 As shown, a warning light 35 is fixedly connected to the side of the support plate 31 near the wear sensor 32. By installing a data line between the wear sensor 32 and the warning light 35, when the wear sensor 32 detects that the wear of the roller 2 exceeds the threshold, the wear sensor 32 transmits a signal to the warning light 35 through the data line to activate the warning light 35. The warning light 35 flashes to warn that the wear of the roller 2 has exceeded the standard and needs to be stopped for replacement.

[0042] Furthermore, such as Figures 2-5 As shown, both ends of the connecting rod 41 are fixedly connected to sliders 43. The connecting rod 41 is slidably connected to the Pilger mill 1 through the sliders 43. By opening a groove on the Pilger mill 1 that matches the slider 43, the connecting rod 41 follows the slider 43 and slides along the groove on the Pilger mill 1. The slider 43 and the groove cooperate to limit the movement path of the connecting rod 41, which helps to improve the stability of the connecting rod 41 when it moves.

[0043] Furthermore, such as Figure 5 As shown, a telescopic rod 44 is fixedly connected between the Pilger mill 1 and the slider 43. A return spring 45 is sleeved on the telescopic rod 44. The return spring 45 is fixedly connected to the Pilger mill 1 and the slider 43. When the rolling roller 2 moves to one side, the connecting rod 41 drives the telescopic rod 44 and the return spring 45 to retract through the slider 43 on one side. The telescopic rod 44 and the return spring 45 on the other side push the slider 43 on the other side to move towards the rolling roller 2, so that the support plates 31 on both sides always maintain stable movement with the rolling roller 2, ensuring that the wear sensor 32 remains in contact with the rolling roller 2.

[0044] Working principle: such as Figures 1-5As shown, by activating the drive device on the Pilger mill 1, the roll support slides on the Pilger mill 1, causing the rolling mill roll 2 to continuously rotate and move back and forth inside the Pilger mill 1. At this time, the rolling mill roll 2 pushes the connecting rod 41 on one side through the push plate 42. The connecting rod 41 drives the support plate 31 to move with the rolling mill roll 2. The connecting rod 41 on the other side drives the slider 43 to move along the groove through the elastic force of the telescopic rod 44 and the return spring 45. This causes the connecting rod 41 on the other side to push the support plate 31 and the wear sensor 32 on the same side to move with the rolling mill roll 2, ensuring that the wear sensor 32 keeps in contact with the rolling mill roll 2. This ensures that the wear sensors 32 on both sides monitor the rolling mill roll 2 simultaneously, ensuring that the monitoring area covers the entire circumference of the rolling mill roll 2 and avoiding blind spots in static detection. Because the two cleaning plates 33 have different widths, they are adapted to the gradually changing rolling groove, allowing for differentiated monitoring of wear characteristics in different areas. The arc surface on the cleaning plate 33 is adapted to the arc surface of the rolling groove on the rolling roller 2, so that the cleaning plate 33 and the rolling roller 2 are tightly attached, which helps to improve the accuracy of detection. When the cleaning plate 33 is attached to the surface of the rolling roller 2, the bristles 34 on the cleaning plate 33 contact the rolling roller 2. Since the bristles 34 have an elastic threaded structure, they buffer the contact pressure between the cleaning plate 33 and the rolling roller 2, reduce rigid wear, and ensure that the cleaning plate 33 removes the metal impurities that adhere to the rolling roller 2 during the rolling of the seamless tube. The cleaned surface is moved to the bottom of the wear sensor 32. The wear sensor 32 is in continuous contact with the rolling roller 2 to monitor the pressure change on the surface of the rolling roller 2 and judge the wear degree of the rolling roller 2. When the wear of the rolling roller 2 exceeds the threshold, the data acquisition and processing system on the Pilger mill 1 transmits the data to the central control system. The early warning and control system activates the early warning light 35 and other early warning devices to notify the operators through sound and light alarms, text messages, emails and other means.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any modifications to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model are acceptable.
