Abstract
Description
A fully automatic adjustable servo blocker Technical Field
[0001] This invention relates to the field of thermoforming production technology. More specifically, this invention relates to a fully automatically adjustable servo stop. Background Technology
[0002] In automotive parts manufacturing, hot forming technology is widely used. Parts manufactured using hot forming processes can greatly improve vehicle collision safety, while also helping to achieve lightweight requirements and contributing to energy conservation and environmental protection in the automotive industry. The basic steps of the hot forming process include: the hot forming production line grabs the stacked sheet metal and sends it to a roller hearth furnace. Driven by the furnace rollers, the sheet metal is heated and held at a certain temperature inside the furnace before being ejected at high speed. Then, the heated sheet metal is positioned by the furnace centering platform, and a robotic arm grabs it and sends it to the press mold for high-speed stamping and pressure holding, cooling, and quenching, ultimately obtaining hot-formed automotive parts with ultra-high strength.
[0003] Typically, a baffle plate is installed at the end of the furnace outlet platform to stop the sheet material from exiting the roller hearth furnace at high speed, thus aligning and positioning it. The sheet material exiting the furnace can be a single sheet or multiple sheets, requiring different baffle plates on the outlet platform to prevent forward movement of the sheet material across its entire width. In practical applications, traditional baffle plates are single-piece structures. The sheet material is prone to displacement after high-speed exit and impact with the baffle plate. Furthermore, since the furnace outlet rollers continue to operate, the offset of the baffle plate relative to the designed exit position on the platform is further increased. This is especially true when the impact end of the sheet material is not a flat straight line, making its tail more prone to rotation, affecting the alignment effect. In such cases, manual adjustment of the sheet material's position is usually required for subsequent precise lateral positioning by the alignment mechanism. This adjustment method is inefficient and poses significant safety hazards. Furthermore, when products are changed or replaced on the thermoforming production line, the changes in the sheet metal's structure and its arrangement on the furnace exit platform necessitate manual adjustments to the front-to-back and left-to-right positions of the baffle plates, or replacement with baffle plates specifically designed for the current sheet metal. These manual operations are time-consuming and labor-intensive, significantly increasing the time required for sheet metal transportation and production line adaptation to product changes. Moreover, manual operation introduces errors, easily leading to deviations in the positions of the sheet metal and baffle plates. This can cause the centering mechanism in subsequent processes to fail to accurately center and position the sheet metal, resulting in feeding deviations and material rejection, severely impacting production stability and efficiency.
[0004] To solve the above problems, it is necessary to design a fully automatic adjustable servo stopper to improve the accuracy and stability of the material stopping action and ensure production efficiency and quality. Summary of the Invention
[0005] The purpose of this invention is to provide a fully automatic adjustable servo stopper. Through horizontal and vertical adjustment devices, the position of each stopper plate in the discharge plane is independently controlled. In conjunction with the multi-segment adjustment structure of the stopper plate, the stopper plate adapts to the impact position and impact end shape of the sheet material, which effectively improves the accuracy and stability of the stopper action and ensures production efficiency and quality.
[0006] To achieve these objectives and other advantages according to the present invention, a fully automatically adjustable servo stop is provided, comprising:
[0007] The track is installed on the end beam along the width of the furnace exit platform;
[0008] Multiple baffle units are spaced apart along the length of the track. Each baffle unit includes a slide plate disposed on and slidably connected to the track; a lateral adjustment device is configured to adjust the displacement of the slide plate on the track; a baffle plate is located at the end of the furnace exit platform and connected to the slide plate via a mounting base, the mounting base being slidably connected to the slide plate along the length of the furnace exit platform; and a longitudinal adjustment device is configured to adjust the displacement of the mounting base on the slide plate.
[0009] The control system is electrically connected to the lateral adjustment device and the longitudinal adjustment device, respectively.
[0010] The baffle plate includes three baffle plates, which are spaced apart along the width of the furnace platform. Any one of the baffle plates is vertically arranged. The middle baffle plate is fixed on the mounting base and its baffle surface is perpendicular to the discharge direction. The ends of the two side baffle plates near the middle baffle plate are respectively hinged to the mounting base. The baffle plate on either side rotates relative to the middle baffle plate under the drive of the driving device. The driving device is electrically connected to the control system.
[0011] Preferably, in the fully automatic adjustable servo stopper, when the impact end face of the sheet metal is parallel to the stop surface of the intermediate stop plate, the two side stop plates are initially set to be located in the same vertical plane as the intermediate stop plate.
[0012] Preferably, in the fully automatic adjustable servo stopper, when the impact end face of the sheet metal is irregular in shape or not parallel to the stop surface of the intermediate stop plate, the angle between the two side stop plates and the intermediate stop plate in the initial state is set according to the shape of the impact end of the sheet metal. The principle for setting the angle is: at the moment of impact, the minimum lateral distance between the side of the impact end of the sheet metal and the stop surface of the stop plate on the same side is equal to the set induction threshold.
[0013] Preferably, the fully automatic adjusting servo stopper moves along the furnace exit platform to abut the stop surface of the middle stop plate after the impact end face of the sheet metal moves to abut the stop surface of the middle stop plate. The two side stop plates rotate at a set angle to abut the sides of the impact end of the sheet metal. The three stop plates together adapt to the shape of the impact end of the sheet metal and are positioned in a three-point conforming posture.
[0014] Preferably, the fully automatic adjustable servo stop further includes multiple lifting devices, which are spaced apart directly below the track along its length. Each lifting device is vertically positioned, with its fixed end mounted on an inherent structure and its pushing end fixedly connected to the bottom of the track for adjusting the height of the track. The lifting device is electrically connected to the control system.
[0015] Preferably, the fully automatic adjustable servo stopper includes a rack fixed at its top along the length of the track; a gear mounted on the slide plate via a rotating shaft and rotatably connected thereto, the gear meshing with the rack; and a lateral drive motor mounted on the slide plate and used to drive the gear to rotate.
[0016] Preferably, the fully automatic adjustable servo stopper includes a longitudinal adjustment device comprising a synchronous belt conveyor fixed to the top of the slide plate, the synchronous belt of the synchronous belt conveyor being arranged along the length direction of the furnace exit platform and moving under the drive of the synchronous belt pulley; a longitudinal drive motor configured to drive the synchronous belt pulley to rotate; a fixing plate fixed to the top surface of the synchronous belt, and the mounting base being mounted on the fixing plate and fixedly connected thereto.
[0017] Preferably, the fully automatic adjustable servo stopper has a horizontally arranged T-shaped mounting base, including a support beam that is arranged along the length of the furnace exit platform and mounted on the slide plate; a double-layer mounting plate that is fixed to the end of the support beam near the furnace exit platform. The double-layer mounting plate includes two mounting plates that are parallel and spaced apart in the vertical direction. Each mounting plate is horizontally arranged along the width of the furnace exit platform and fixedly connected to the support beam in the middle. The two mounting plates are respectively fixed to the top and bottom of the support beam, and the baffle plate is arranged on the side of the mounting plate away from the support beam.
[0018] Preferably, in the fully automatic adjustable servo stopper, the ends of the two side stop plates near the middle stop plate are respectively hinged to the mounting base via a drive shaft, the drive shaft being vertically arranged between the two mounting plates and rotatably connected thereto; the driving device includes a drive motor, which is arranged on the mounting plate and used to drive the corresponding drive shaft to rotate.
[0019] The present invention has at least the following beneficial effects:
[0020] 1. This invention independently controls the position of each baffle plate in the discharge plane through horizontal and vertical adjustment devices. The baffle plate adopts a three-section structure. By adjusting the rotation angle of the baffle plates on both sides relative to the middle baffle plate, the baffle plate can adaptively limit the shape of the impact end of the plate. It can be widely applied to the discharge control of various plates with different shapes, sizes and structures, effectively improving the accuracy and stability of the baffle action, and ensuring production efficiency and production quality.
[0021] 2. This invention employs a control system to centrally control the working status of each drive mechanism. The control system can automatically match the required position and state of the baffle plate according to the preset sheet material parameters, thereby accurately controlling the working status and stroke of each drive mechanism at different times, ensuring that the position and posture of each baffle plate in the corresponding baffle state are accurate and reliable. If it is necessary to switch products (sheet materials) or make online position adjustments on the production line, the product switching and online adjustment can be completed by calling and modifying the built-in parameters of the control system. Compared with the existing conventional heating furnace baffles, it does not require operators to enter the heating furnace outlet platform area for manual adjustment, nor does it require interrupting production, which greatly reduces the impact of line change operations on the production process. While reducing human resource costs, it effectively ensures production efficiency and quality, and improves production safety and stability.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0032] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

Therefore, they should not be construed as limitations on this invention.
[0033] As shown in Figures 1-6, the present invention provides a fully automatic adjustable servo stopper, comprising:
[0034] Track 21 is installed on its end crossbeam 11 along the width direction of the furnace exit platform 1;
[0035] Multiple baffle units are spaced apart along the length of the track 21. Each baffle unit includes a slide plate 22, which is mounted on and slidably connected to the track 21. A lateral adjustment device 4 is configured to adjust the displacement of the slide plate 22 on the track 21. A baffle plate 3 is located at the end of the furnace exit platform 1 and is connected to the slide plate 22 via a mounting base 7, which is slidably connected to the slide plate 22 along the length of the furnace exit platform 1. A longitudinal adjustment device 5 is configured to adjust the displacement of the mounting base 7 on the slide plate 22.
[0036] The control system is electrically connected to the lateral adjustment device 4 and the longitudinal adjustment device 5, respectively.
[0037] The baffle plate includes three baffle plates, which are spaced apart along the width of the furnace platform 1. Each baffle plate is vertically arranged. The middle baffle plate 32 is fixed on the mounting base 7 and its baffle surface is perpendicular to the discharge direction. The ends of the two side baffle plates near the middle baffle plate 32 are respectively hinged to the mounting base 7. The baffle plate on either side rotates relative to the middle baffle plate 32 under the drive of the driving device. The driving device is electrically connected to the control system.
[0038] In the above technical solution, the fully automatic adjustable servo stopper is installed at the end of the furnace exit platform 1 of the thermoforming automated production line to block the sheet metal 10 that has been heated and exited from the furnace. Multiple stopper units correspond to the number of sheets arranged within the width range of the exit platform. The plane where the sheet metal moves on the exit roller conveyor and contacts the stopper plate is the exit plane. The control system controls the lateral and longitudinal adjustment devices according to the arrangement of the sheets on the exit platform, ensuring that each stopper plate is aligned with the impact end of the corresponding sheet metal. This system can be widely applied to the exit process of sheets with different structures and arrangements, and requires no manual adjustment during the impact process. Simultaneously, each stopper plate is configured as a three-section stopper plate structure. The two side stopper plates can be automatically adjusted in angle by a drive device. During the impact process, they adapt to the shape of the impact end of the corresponding sheet metal in a conformal state and limit its movement (longitudinal + lateral), thus enabling the stopper plates to better block the sheet metal and ensure good stability of the sheet metal after high-speed exit impact, providing a better stable posture for subsequent sheet metal alignment and positioning. In addition, the control system can automatically match the required position and state of the baffle plate according to the preset sheet material parameters, thereby accurately controlling the working state and stroke of each drive mechanism (including the lateral adjustment device, the longitudinal adjustment device, and the drive device) at different times, ensuring that the position and posture of each baffle plate in the corresponding baffle state are accurate and reliable. If it is necessary to switch products (sheet materials) or make online position adjustments on the production line, the product switching and online adjustment can be completed by calling and modifying the built-in parameters of the control system. Compared with the existing conventional heating furnace baffles, it does not require operators to enter the heating furnace outlet platform area for manual adjustment, nor does it require interruption of production, which greatly reduces the impact of line change and other operations on the production process. While reducing human resource costs, it effectively ensures production efficiency and quality, and improves production safety and stability.
[0039] In practical applications, the positions of the baffle plates are first adjusted according to the arrangement of the sheet metal on the furnace platform and the structure of each sheet metal (the midpoint position of each sheet metal). This is achieved through the lateral and longitudinal adjustment devices of each baffle unit, ensuring that the middle baffle plate 32 is aligned with the impact end of the corresponding sheet metal 10 and adapts to its width range. Then, after detecting an impact between the sheet metal and the baffle plate, the rotation angle of the two side baffle plates relative to the middle baffle plate is adjusted according to the shape of the impact end of the sheet metal. This allows the baffle plate to perform three-point contour positioning based on the shape of the impact end of the sheet metal (i.e., the three baffle plates respectively abut against three points on the impact end of the sheet metal), ensuring the positional and posture stability of the sheet metal after impact. The above adjustment process is all automatically controlled by the control system, which includes a controller and a control panel. The controller controls the working status and parameters of each component, while the control panel displays the corresponding working parameters and allows for external input and adjustment of working parameters, enabling online adjustment of the working status of the baffle. Specifically, the shape and structure data of each sheet in the production line are stored in the control system. When in use, the corresponding sheet data can be directly retrieved. After inputting the arrangement of each sheet (the horizontal coordinates and spacing on the furnace exit platform) externally, the control system can automatically calculate the horizontal and vertical setting coordinates of the corresponding baffle plate and control the horizontal and vertical adjustment devices to drive the baffle plate to the designed position. The control system reads the shape of the impact end of the corresponding sheet according to the corresponding sheet data and automatically calculates the setting shape of the baffle plate in the positioning state (the rotation angle of the two side baffle plates relative to the middle baffle plate), so that the baffle plate can automatically perform contour positioning according to the shape of the impact end of the sheet after impact. The control system also has an impact recognition function. It can determine the time of impact by calculating the time of the sheet's movement from the furnace exit platform to the middle baffle plate (the longitudinal distance from the beginning of the furnace exit platform to the middle baffle plate / the translation speed of the sheet on the roller conveyor) or by real-time image recognition, and adjust the attitude (angle) of the baffle plate at the corresponding time.
[0040] In another technical solution, the fully automatic adjustable servo stopper, when the impact end face of the sheet metal 10 is parallel to the stop surface of the intermediate stop plate 32, the two side stop plates are initially set to be located in the same vertical plane as the intermediate stop plate 32. In the initial state (before impact), the setting angle of the two side stop plates needs to be set according to the shape of the impact end of the sheet metal. When the impact end face of the sheet metal is parallel to the stop surface of the intermediate stop plate, no other lateral force will be generated on the sheet metal at the moment of impact. At this time, as shown in Figure 6, setting the three stop plates at 0° (i.e., the three stop plates are spaced apart on the same vertical plane) can meet the impact requirements.
[0041] In another technical solution, when the impact end face of the sheet metal 10 is irregular or not parallel to the blocking surface of the intermediate blocking plate 32, the angle between the two blocking plates and the intermediate blocking plate 32 in the initial state is set according to the shape of the impact end of the sheet metal 10. The principle for setting the angle is: at the moment of impact, the minimum lateral distance between the side of the impact end of the sheet metal 10 and the blocking surface of the blocking plate on the same side is equal to the set induction threshold. In the initial state (before impact), the angle of the baffle plates on both sides needs to be set according to the shape of the impact end of the plate. When the impact end of the plate is a point impact, the end face is at a certain angle to the middle baffle plate, or other irregular end (such as the impact end is an arc shape), the plate tail is prone to rotation and displacement after impact due to uneven force on the impact end, which affects the stability of the plate's centering and positioning on the furnace platform. Therefore, at this time, the baffle plates on both sides need to be set at a certain angle so that the three baffle plates together present a certain range of funnel-shaped opening. When the plate runs into the opening range of the baffle plate, the baffle plates on both sides simultaneously play the role of guiding and limiting the impact end of the plate, so that the impact end of the plate can smoothly enter the opening range of the baffle plate. At the same time, it ensures that the plate that may deviate can still be within a certain limited range after impact, avoiding large deviations in the plate's posture or position, which would affect the centering and positioning of the subsequent plate. The principle for setting the baffle plate opening shape (i.e., the rotation angle of the two baffle plates relative to the middle baffle plate) is as follows: at the moment of impact, the minimum lateral distance between the impacting end side of the plate and the baffle surface of the same side baffle plate is equal to the set induction threshold. In this embodiment, the induction threshold is set to 50mm, that is, at the moment of impact, the lateral distance (distance along the width direction of the furnace platform) between the most protruding position of the impacting end side of the plate and the baffle surface of the same side baffle plate is guaranteed to be 50mm. From this, the rotation angle of the two baffle plates relative to the middle baffle plate can be calculated, as shown in Figure 4. The two baffle plates are set at a certain angle to the middle baffle plate under the current induction threshold, which can meet the impact requirements in the initial state.
[0042] In another technical solution, the fully automatic adjusting servo stopper moves along the furnace exit platform 1 to abut against the stop surface of the intermediate stop plate 32 after the impact end face of the sheet 10 moves. Then, the two side stop plates rotate at a set angle to abut against the sides of the impact end of the sheet 10. The three stop plates together adapt to the shape of the impact end of the sheet in a three-point conforming posture and are positioned accordingly. In the above technical solution, after the sheet reaches the impact stop plate, the stop plate is switched to a positioning state. The two side stop plates continue to adjust their rotation angle relative to the intermediate stop plate according to the designed positioning position and shape of the sheet, so that the stop plate ultimately forms a three-point conforming state adapted to the impact end of the sheet (as shown in Figure 5). This optimizes the sheet's posture and provides coarse positioning, ensuring that the sheet maintains a stable positioning posture after impact, providing a stable and reliable foundation for the next step of centering pusher positioning.
[0043] In another technical solution, the fully automatic adjustable servo stopper also includes multiple lifting devices 6, which are spaced apart directly below the track 21 along its length. Each lifting device 6 is vertically positioned, with its fixed end mounted on a pre-existing structure. Its pushing end is fixedly connected to the bottom of the track and used to adjust the height of the track. The lifting device is electrically connected to the control system. The fixed end of the lifting device can be fixed to the ground, the furnace platform support, or other pre-existing structures to ensure the stability of the lifting action. When the sheet metal has defects or an alignment failure occurs, the pushing end of the lifting device automatically lifts the track, causing the stopper to move away from the sheet metal's discharge plane (the fixed connection between the track and the end beam of the furnace platform is released before lifting), freeing up the discharge space at the end of the furnace platform for heating the grate waste. Specifically, the lifting device can be configured as a vertical lifting cylinder.
[0044] In another technical solution, the fully automatic adjustable servo stopper includes a lateral adjustment device 4 comprising a rack 41 fixed at its top along the length of the track 21; a gear 42 mounted on the slide plate 22 via a rotating shaft and rotatably connected thereto, the gear 42 meshing with the rack 41; and a lateral drive motor 43 mounted on the slide plate 22 and used to drive the gear 42 to rotate. The lateral position of the stopper is stably adjusted by the lateral drive motor driving the gear to rotate relative to the rack. Each lateral adjustment device is driven by a separate servo motor, making the lateral travel of each stopper individually adjustable, thus better adapting to the collision requirements of different sheet materials in various sheet material arrangement configurations.
[0045] In another technical solution, the fully automatic adjustable servo stopper includes a longitudinal adjustment device 5 comprising a synchronous belt conveyor 52 fixed to the top of the slide plate 22, the synchronous belt of the synchronous belt conveyor 52 being arranged along the length of the furnace platform 1 and moving under the drive of the synchronous belt pulley; a longitudinal drive motor configured to drive the synchronous belt pulley to rotate; and a fixed plate 51 fixed to the top surface of the synchronous belt, with the mounting base 7 mounted on and fixedly connected to the fixed plate 51. The longitudinal travel of the baffle plate is adjusted via synchronous belt transmission. The fixed bracket of the synchronous belt conveyor is fixed to the top of the slide plate, and the top surface of the synchronous belt conveys along the length of the furnace platform. Fixing the mounting base to the fixed plate achieves stable adjustment of the longitudinal displacement of the baffle plate. Due to the longitudinal distance difference between the installation positions of the slide plate and the baffle plate, the synchronous belt transmission method can better connect the mounting base and the baffle plate and ensure stable transmission. Each longitudinal adjustment device is driven by a separate servo motor, making the longitudinal travel of each baffle plate individually adjustable, better adapting to the collision requirements of different plates in various plate arrangement configurations.
[0046] In another technical solution, the fully automatic adjustable servo stopper has a horizontally arranged T-shaped mounting base 7, including a support beam 71, which is arranged along the length of the furnace platform 1 and mounted on the slide plate 22; and a double-layer mounting plate, which is fixed to the end of the support beam 71 near the furnace platform 1. The double-layer mounting plate includes two mounting plates arranged parallel to each other in the vertical direction. One mounting plate is horizontally arranged along the width of the furnace platform and fixedly connected to the support beam in the middle. The two mounting plates are respectively fixed to the top and bottom of the support beam, and the baffle plate is arranged on the side of the mounting plate away from the support beam. The support beam is the vertical part of the T-shaped structure, and the mounting plate is the horizontal part of the T-shaped structure. Both are horizontally arranged, and the two mounting plates are divided into a top plate 72 and a bottom plate 73 according to their vertical positions, forming a stable three-dimensional support structure at the end of the support beam, facilitating the installation of the baffle plate on the other side. In this embodiment, the support beam is made of aluminum profile, and the mounting plate is made of square sheet material and welded to the top and bottom surfaces of the support beam, forming a stable vertical support surface on the side near the furnace platform.
[0047] In another technical solution, the fully automatic adjustable servo stopper has its two side stop plates, near the middle stop plate 32, hinged to the mounting base 7 via drive shafts 9. The drive shafts 9 are vertically positioned between the two mounting plates and rotatably connected to them. The driving device includes a drive motor, which is mounted on the mounting plate 7 and used to drive the corresponding drive shafts 9 to rotate. The vertically positioned drive shafts between the two mounting plates provide a stable base for the rotation of the side stop plates, and the drive motor is a servo motor.
[0048] In this embodiment, the fully automatic adjustable servo stopper has four stopping units. These four stopping units and the track form an integral structure, driven by a vertically positioned lifting device 6 to achieve overall lifting, facilitating the disposal of waste materials from the heating furnace. The following description uses the operation and adjustment of one of the stopping units as an example to illustrate its working method:
[0049] The baffle plate is mounted on the fixed plate 51 of the longitudinal adjustment device via the mounting base 7 and moves with the synchronous belt. The longitudinal adjustment device 5 is mounted on the slide plate 22 and is driven by the lateral adjustment device 4 to slide along the track 21. Thus, by controlling the working state of the lateral drive motor, the lateral displacement of the baffle plate on the discharge plane (displacement along the width direction of the furnace platform) can be controlled. By controlling the working state of the longitudinal drive motor, the longitudinal displacement of the baffle plate on the discharge plane (displacement along the length direction of the furnace platform) can be controlled. By comprehensively adjusting the displacement of the baffle plate on the discharge plane, the baffle plate's blocking surface can be aligned with the impact end of the plate material. In addition, the support beam 71 serves as the longitudinal support of the baffle plate and is mounted on the fixed plate via two L-shaped plates. The longitudinal travel range of the baffle plate (i.e., adjusting the longitudinal installation position of the support beam relative to the fixed plate) can be adjusted manually between the support beam and the L-shaped plates. This is a backup function that can expand the longitudinal adjustment range of the baffle plate, allowing the baffle plate travel to meet the arrangement requirements of different plates.
[0050] The baffle plate is located at the end of the furnace outlet platform and its height corresponds to the outlet plane of the plate. The baffle plate is installed on the top and bottom plates at the end of the support beam. The layered structure of the top and bottom plates enables the vertically installed baffle plate to be stably connected (forming a three-dimensional support structure), ensuring the stability and positioning accuracy of the baffle plate during operation and movement. The baffle plate consists of a middle baffle plate 32, and two baffle plates 31 and 33 located on either side. These three baffle plates move synchronously with the mounting base in the transverse and longitudinal directions. The middle baffle plate 32 is fixed to the side wall of the top plate 72 and bottom plate 73 away from the support beam 71, and is fixedly positioned facing the impact end face of the corresponding plate 10. The first and second baffle plates are mounted on two drive shafts 9 between the top and bottom plates. Drive devices are correspondingly mounted on the top plate. The drive device corresponding to the first baffle plate 31 is designated as the first drive device 81, and the drive device corresponding to the second baffle plate 33 is designated as the second drive device 82. The control system can adjust the rotation angle of the corresponding drive shafts 9 by adjusting the working state of the first drive device 81 and the second drive device 82, thereby adjusting the rotation angle of the first baffle plate 31 and the second baffle plate 33 relative to the middle baffle plate 32. Each baffle plate adopts a square sheet structure with a continuously arranged serrated structure at its bottom.
[0051] In the initial state, the three-section baffle is set to guide and longitudinally limit the impact process. Specifically, for ordinary sheet metal with a flat vertical surface at the impact end (parallel to the baffle surface of the middle baffle), the three-section baffle can be combined in a planar arrangement (as shown in Figure 6) to meet the requirements. For sheet metal with an irregularly shaped impact end, it is easy to deviate or rotate during the impact process, and the stable posture of the sheet metal after impact cannot be guaranteed. Therefore, the baffles on both sides need to be set at a certain angle so that the three-section baffle presents a certain range of funnel-shaped opening (as shown in Figure 4). When the sheet metal runs into the area of the baffle, the baffles on both sides can also guide the sheet metal, so that the sheet metal, which may deviate to a certain extent at the moment of impact, can smoothly hit the opening range of the baffle and abut against the middle baffle.
[0052] After the impact occurs (i.e., the impact end face of the sheet moves along the furnace exit platform and impacts / abuts with the baffle surface of the intermediate baffle), the rotation angle of the first and second baffles is adjusted according to the designed position and shape of the sheet after positioning, so that the baffle is in a positioning state (as shown in Figure 5). That is, the first and second baffles press down on the impact end of the sheet from both sides and adjust its posture to be the same as the design shape, finally forming a three-point conforming state that adapts to the shape of the impact end of the sheet, thereby achieving coarse positioning of the sheet and ensuring that the sheet can maintain a stable normal posture while rolling on the furnace exit roller after impact, providing a stable and reliable foundation for the next step of centering pusher positioning (fine positioning).
[0053] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.

A fully automatic adjustable servo stopper, characterized in that, include: The system comprises: a track, which is mounted on a crossbeam at its end along the width of the furnace discharge platform; multiple baffle units, which are spaced apart along the length of the track, each baffle unit including a sliding plate, which is mounted on and slidably connected to the track; a lateral adjustment device for adjusting the displacement of the sliding plate on the track; a baffle plate located at the end of the furnace discharge platform and connected to the sliding plate via a mounting base, the mounting base being slidably connected to the sliding plate along the length of the furnace discharge platform; a longitudinal adjustment device for adjusting the displacement of the mounting base on the sliding plate; and a control system electrically connected to the lateral and longitudinal adjustment devices; wherein the baffle plate includes three baffle plates spaced apart along the width of the furnace discharge platform, each baffle plate being vertically positioned, the middle baffle plate being fixed to the mounting base with its baffle surface perpendicular to the discharge direction, and the ends of the two side baffle plates near the middle baffle plate being hinged to the mounting base. The baffle plates on either side rotate relative to the middle baffle plate under the drive of the driving device, which is electrically connected to the control system. When the impact end face of the sheet metal is parallel to the baffle surface of the middle baffle plate, the baffle plates on both sides are initially set to be located in the same vertical plane as the middle baffle plate. When the impact end face of the sheet metal is not parallel to the baffle surface of the middle baffle plate, the angle between the baffle plates on both sides and the middle baffle plate in the initial state is set according to the shape of the impact end of the sheet metal. The principle for setting the angle is: at the moment of impact, the minimum lateral distance between the side of the impact end of the sheet metal and the baffle surface of the baffle plate on the same side is equal to the set threshold. After the impact end face of the sheet metal moves along the furnace exit platform to abut against the baffle surface of the middle baffle plate, the baffle plates on both sides rotate according to the set angle to abut against the side of the impact end of the sheet metal. The three baffle plates together adapt to the shape of the impact end of the sheet metal and are positioned in a three-point conforming posture.
2. The fully automatic adjustable servo stopper as described in claim 1, characterized in that, It also includes multiple lifting devices, which are spaced apart directly below the track along its length. Each lifting device is vertically positioned, with its fixed end mounted on the inherent structure and its pushing end fixedly connected to the bottom of the track and used to adjust the height of the track. The lifting device is electrically connected to the control system.
