Description

Technical Field

[0001] This invention relates to the field of curved steel shell technology, and more particularly to a processing apparatus and processing method for curved steel shells. Background Technology

[0002] Curved steel shells are steel structural components with specific curved surface shapes. By optimizing their geometry, they can achieve high strength and stiffness with a relatively light weight, making them suitable for large-span structures. In aerospace, construction, bridges, and machinery manufacturing, curved steel shells not only serve as load-bearing structures but also have aesthetic and space optimization functions. Their surfaces are curved, and they are formed by pressing, cutting, and grinding steel plates using specially designed molds based on the curved shape of the steel shell. Common types include cylindrical shells, spherical shells, and corrugated shells.

[0003] In existing technologies, steel plates are typically fixed using clamps, pressure plates, or robotic arms. However, during mechanical clamping, the clamps are in direct contact with the surface of the steel plate, which can easily cause surface defects such as scratches and indentations, affecting the quality of subsequent processing. At the same time, during the grinding process of the cut steel plate, rigid grinding tools are difficult to adapt to the curved shape of the steel plate, which can easily lead to uneven grinding, leaving scratches or dents, affecting the surface finish. Furthermore, the grinding debris generated during the grinding process remains on the surface of the steel plate, which can cause poor contact between the mold and the steel plate, thereby affecting the accuracy and effect of pressing. Summary of the Invention

[0004] In the prior art, the fixture is in direct contact with the surface of the steel plate, which easily produces surface defects such as scratches and indentations. At the same time, rigid grinding tools are difficult to adapt to the curved shape of the steel plate, which easily leads to uneven grinding. Furthermore, the grinding debris generated during the grinding process remains on the surface of the steel plate, which can cause technical problems such as poor contact between the mold and the steel plate. This invention proposes a processing device and processing method for curved steel shells.

[0005] The present invention proposes a processing device for curved steel shells, including a frame with an electric guide rail, and further including a transport mechanism, a processing mechanism and a pressing mechanism installed within the frame.

[0006] A transport mechanism is located inside the bottom end of the frame and transports the steel plate. The transport mechanism includes an electric adsorption platform, which uses vacuum adsorption to adsorb and fix the steel plate.

[0007] A processing mechanism is located inside the top of the frame and processes the steel plate. The processing mechanism includes an adjustment component and a processing component. The adjustment component includes a moving frame. The movement of the moving frame drives the processing component to move. The processing component includes a grinding roller. The rotation of the grinding roller grinds the cut edges of the steel plate.

[0008] A pressing mechanism is located inside the bottom end of the frame and presses the cleaned steel plate to form a curved steel shell. The pressing mechanism includes a cleaning component and a pressing component. The cleaning component includes a flexible cleaning sponge, which achieves comprehensive wiping by closely adhering to the surface and circumference of the steel plate. The pressing component includes a lower mold and an upper mold. After the lower mold moves, it closes and presses with the upper mold to form the steel plate into a preset curved steel shell within the mold cavity.

[0009] Preferably, the transport mechanism further includes a support tube, the two ends of the support tube being connected to the electric guide rail of the frame via built-in rollers, the inner wall of the support tube being rotatably connected to a support frame with gears via bearings, and the outer surface of the support frame's support rod being slidably connected to the arc-shaped limiting groove of the support tube.

[0010] Through the above technical solution, the guide rail sliders at both ends of the support tube are rolledly connected to the electric guide rail, which fixes the support tube while driving it to move. The support tube and the guide rail sliders are fixedly installed with bolts, which makes it easy to disassemble while fixing it. The support tube is rotatably connected to the support frame through bearings, which drives it to move synchronously without affecting the rotation of the support frame. The arc-shaped limiting groove of the support frame and the support tube are slidably connected to limit the rotation of the support frame and prevent it from rotating excessively.

[0011] Preferably, the electric adsorption platform is fixedly installed on the upper surface of the support plate of the support frame by bolts, and an electromagnetic brake is fixedly installed on the inner bottom wall of the support tube. The brake disc of the electromagnetic brake is fixedly installed to the arc surface of the rotating rod of the support frame by fastening bolts.

[0012] Through the above technical solution, the electric adsorption table is fixed to the support frame with bolts, which facilitates disassembly and replacement for subsequent maintenance. The vacuum adsorption system performs non-contact adsorption and fixation of the steel plate, ensuring that the steel plate is stable and does not shift during transportation, avoiding scratches or indentations on the steel plate surface caused by traditional clamps. It is also suitable for steel plates of different sizes and shapes, with strong versatility. The support tube is fixed to the electromagnetic brake, and the brake disc of the electromagnetic brake is fixed to the rotating rod of the support frame with fastening bolts. This is used to accurately position and lock the rotation angle of the support frame, ensuring that the support frame will not rotate unexpectedly during processing, thus improving processing accuracy and safety.

[0013] Preferably, the adjustment component further includes a movable electric push rod, which is fixedly installed on the inner side wall of the top of the frame. A movable frame is fixedly installed at one end of the telescopic rod of the movable electric push rod, and the guide rail sliders at both ends of the movable frame are rotatably connected to the top guide rail of the frame through built-in rollers.

[0014] The above technical solution involves fixing the movable electric push rod to the frame, and fixing the frame to the movable frame via the telescopic rod of the movable electric push rod. The extension and retraction of the telescopic rod causes the movable frame to move on the guide rail, so as to adjust the X-axis position of the processed part. The guide rail ensures the stability of the movement of the movable frame.

[0015] Preferably, a mobile motor is fixedly installed at one end of the mobile frame, and the output shaft of the mobile motor is rotatably connected to the inner wall of the groove at one end of the mobile frame through a bearing. A mobile screw is fixedly installed on the output shaft of the mobile motor, and the mobile screw is rotatably connected to the inner wall of the mobile frame through a bearing. An adjustment frame is threadedly connected to the outer surface of the mobile screw, and the guide rail slider of the adjustment frame is rotatably connected to the guide rail of the mobile frame through a built-in roller. A lifting electric push rod is fixedly installed on the inner wall of the adjustment frame, and one end of the telescopic rod of the lifting electric push rod is fixedly installed to the upper surface of the mobile frame. The sliding rod of the mobile frame is slidably inserted into the inner wall of the groove on the outer surface of the mobile frame.

[0016] The above technical solution involves fixing the movable frame and the movable motor together. The output shaft of the movable motor is rotatably connected to the movable frame via bearings, ensuring the stability of the movable motor's output shaft rotation. The output shaft of the movable motor is also fixedly installed with a movable screw, driving the screw to rotate. The movable screw is rotatably connected to the movable frame via bearings, ensuring the stability of the screw's rotation. The movable screw is threadedly connected to an adjustment frame, driving it to rotate and move. However, because the guide rail slider of the adjustment frame is rolledly connected to the guide rail of the movable frame via built-in rollers, it is limited, allowing only movement to be made, thus adjusting the Y-axis position of the processed part. The adjustment frame is fixedly installed with a lifting electric push rod, which moves synchronously while being fixed. The telescopic rod of the lifting electric push rod is fixedly installed with the movable frame, and the extension and retraction of the telescopic rod causes the movable frame to rise and fall on the movable frame, thus adjusting the Z-axis position of the processed part.

[0017] Preferably, the processing component further includes a processing motor, which is fixedly installed on the inner top wall of the movable frame. The output shaft of the processing motor is rotatably connected to the inner side wall of the movable frame through a bearing seat. A cutting screw with gears is fixedly installed on the output shaft of the processing motor. The cutting screw is rotatably connected to the inner bottom wall of the movable frame through a bearing. A cutting frame is threadedly connected to the outer surface of the cutting screw. A guide rail slider at one end of the cutting frame is rotatably connected to the guide rail of the movable frame through a built-in roller. A laser instrument housing is fixedly installed on the lower surface of the cutting frame by bolts.

[0018] The above technical solution involves fixing the moving frame to the processing motor, which in turn drives the motor to move synchronously. The output shaft of the processing motor is rotatably connected to the moving frame via a bearing seat, ensuring the stability of the motor's output shaft rotation. The output shaft of the processing motor is also fixedly installed to the cutting screw, driving its rotation. The cutting screw is rotatably connected to the moving frame via a bearing, ensuring the stability of its rotation. The cutting screw is threadedly connected to the cutting frame, driving its rotation and lifting. However, because the guide rail slider at one end of the cutting frame is rotatably connected to the guide rail of the moving frame via a built-in roller, it is limited, allowing the frame to only lift. The cutting frame is fixedly installed to the laser instrument housing via bolts, driving it to lift synchronously, so as to cut the steel plate along a preset path.

[0019] Preferably, a vision sensor is fixedly installed on the lower surface of the movable frame. A grinding screw with gears is rotatably connected to the inner wall of the movable frame via a bearing. The gears of the grinding screw mesh with the gears of the cutting screw. The threads of the grinding screw and the cutting screw have the same direction. A grinding frame is threadedly connected to the outer surface of the grinding screw. A guide rail slider at one end of the grinding frame is rotatably connected to the guide rail of the movable frame via a built-in roller. A grinding motor is fixedly installed on the inner top wall of the grinding frame. The output shaft of the grinding motor is rotatably connected to the inner side wall of the grinding frame via a bearing seat. The output shaft of the grinding motor is fixedly installed to one end of the grinding roller. A support rod is slidably inserted into the groove of the grinding roller. One end of the support rod is fixedly installed to a spring in the groove of the grinding roller. A flexible grinding layer is fixedly bonded to the outer surface of the support rod.

[0020] The above technical solution involves fixing a moving frame to a vision sensor for real-time monitoring of the steel plate's cutting and grinding status. Image data is fed back to the control system, dynamically adjusting the cutting path and grinding pressure. The moving frame is rotatably connected to the grinding screw via bearings, ensuring rotational stability. The grinding screw's gear meshes with the cutting screw's gear, causing them to rotate synchronously. Since the threads of the grinding and cutting screws are in the same direction, and the gear meshing results in opposite rotation directions, a clockwise rotation of the cutting screw lowers the cutting frame, while a counter-clockwise rotation of the grinding screw raises the grinding frame, and vice versa. This allows the cutting and grinding processes to be performed alternately. The grinding screw is threadedly connected to the grinding frame, driving its rotation and lifting. However, because the guide rail slider at one end of the grinding frame rolls with the guide rail of the moving frame via built-in rollers... The system is connected and limited to allow only lifting and lowering. A grinding frame is fixedly installed to the grinding motor, simultaneously driving its synchronous lifting and lowering. The grinding motor is fixedly installed to the grinding roller, driving its rotation. A support rod is slidably inserted into the grinding roller, allowing it to rotate without affecting its extension and retraction. A spring inside the grinding roller is fixedly installed to the support rod, allowing it to return to its original position after retraction. This allows the flexible grinding layer, fixedly bonded to the support rod, to automatically adjust pressure according to the irregular shape of the steel plate edge, ensuring uniform grinding and avoiding over- or under-grinding. The flexible grinding layer uses high-elasticity polyurethane or nitrile rubber as the base material, with a layer of silicon carbide or alumina abrasive bonded to its surface. The abrasive grit size is selected according to processing requirements to ensure grinding efficiency and surface quality. Epoxy resin or polyurethane adhesive can be used to ensure a strong bond between the abrasive layer and the base material.

[0021] Preferably, the cleaning component further includes a cleaning frame with through holes. The cleaning frame is fixedly installed on the lower surface of the outer support plate of the movable frame by bolts. A fan is fixedly installed on the outer side of the frame. The air inlet of the fan is fixedly connected to the outer surface of the cleaning frame through a hose. The air outlet of the fan is fixedly connected to an air outlet pipe. A cleaning plate with multiple bolt holes is fixedly installed in the outer groove of the frame by bolts. The flexible cleaning sponge is fixedly installed on the outer surface of the cleaning plate by bolts.

[0022] Through the above technical solution, the cleaning frame is fixedly installed to the moving frame with bolts, which facilitates disassembly while securing it. The cleaning frame has a U-shaped structure with a through hole on its lower surface. The air inlet of the blower is fixedly connected to the cleaning frame through a hose. Air is drawn from the through hole of the cleaning frame to form a negative pressure area. Metal shavings and dust generated during the grinding process are sucked into the cleaning frame and transported to the air inlet of the blower through the hose. The blower transports the sucked-in shavings through the air outlet to subsequent processing equipment, such as dust collectors and filtration systems, to achieve centralized processing and recycling of shavings. The frame and cleaning plate are fixedly installed with bolts, and the cleaning plate is fixedly installed to the flexible cleaning sponge with bolts, which facilitates disassembly while securing it. Multiple bolt holes are opened on the cleaning plate to adjust the installation height of the flexible cleaning sponge on the cleaning plate according to the thickness of the steel plate. Thus, during the movement of the steel plate, the sponge thoroughly wipes the surface and surrounding area of ​​the steel plate to remove residual shavings.

[0023] Preferably, the pressing component further includes a rack, which is fixedly installed on the inner side wall of the frame by bolts. The rack meshes with the gear of the support frame. A pressing electric push rod is fixedly installed on the inner bottom wall of the frame. One end of the telescopic rod of the pressing electric push rod is fixedly installed on the lower surface of the lower mold. The outer surface of the support rod of the lower mold is slidably inserted into the groove of the inner bottom wall of the frame. The upper mold is fixedly installed on the inner top wall of the frame.

[0024] Through the above technical solution, the rack is fixedly installed to the frame with bolts. The rack meshes with the gears of the support frame, causing the support frame to deflect within the support tube. The installation position and length of the rack need to be set according to the actual working conditions to ensure that after the support frame rotates 180 degrees, the steel plate on the electric adsorption platform is directly above the mold cavity of the lower mold. It is fixedly installed to the frame and the pressing electric push rod. The extension rod of the pressing electric push rod is fixedly installed to the lower mold. The extension and retraction of the extension rod can drive the lower mold to rise and fall. When the steel plate is directly below the lower mold, the pressing electric push rod can drive the lower mold to a suitable height, so that after the electric adsorption platform releases its adsorption, the steel plate accurately falls into the mold cavity of the lower mold, preventing displacement of the steel plate during descent due to excessive distance, thus improving positioning accuracy. The upper mold is fixedly installed to the frame. Both the lower and upper molds can be fixedly installed with bolts for easy replacement. The shape of the mold cavity can be customized according to requirements to adapt to the processing of different curved steel shells.

[0025] The present invention proposes a processing method for a curved steel shell processing device, comprising the following steps: S1: When it is necessary to transport steel plates, the staff places the cleaned steel plates on the electric adsorption table, starts the vacuum adsorption system of the electric adsorption table to adsorb and fix the steel plates, and then starts the electric guide rail of the frame to drive the support tube and its upper structure to move along the guide rail. When the steel plates are transported to the bottom of the processing mechanism, the electric guide rail is turned off. S2: When cutting the steel plate is required, start the processing motor inside the moving frame to drive the cutting screw to rotate clockwise. Since the cutting screw and the grinding screw rotate in the same direction, the cutting screw causes the grinding screw to rotate counterclockwise through gear transmission. At this time, the cutting screw drives the threaded cutting frame to descend along the guide rail, while the grinding screw drives the threaded grinding frame to rise along the guide rail. The descent of the cutting frame causes the laser instrument housing to descend synchronously to the cutting position. When the X-axis position of the laser instrument housing needs to be adjusted, start the moving electric push rod. The movement of its telescopic rod drives the moving... The frame moves, and when the Y-axis position of the laser housing needs to be adjusted, the moving motor is started to drive the moving screw to rotate, thereby driving the adjustment frame connected to it to move along the guide rail. When the Z-axis position of the laser housing needs to be adjusted, the lifting electric push rod is started, and the extension and retraction of its telescopic rod drives the moving frame to rise and fall, thereby driving the laser housing inside the moving frame to adjust its position so that it can cut the steel plate according to the preset curve path. The fragments produced by cutting fall naturally to the bottom of the frame because the surface area of ​​the cut steel plate is still larger than that of the electric adsorption table. S3: When the cut steel plate needs to be polished, the processing motor is started to drive the cutting screw to rotate counterclockwise, causing the cutting frame to rise and the polishing frame to fall. The position adjustment program of the polishing roller is the same as that of the laser instrument housing. When the polishing roller is adjusted to the appropriate position and the flexible polishing layer on it contacts the cutting edge of the steel plate, the polishing motor is started to drive the polishing roller to rotate. The polishing roller drives the flexible polishing layer to rotate synchronously through the support rod, thereby polishing the edge of the steel plate. During the polishing process, the support rod pushes the flexible polishing layer to always fit the edge of the steel plate under the action of the spring force, realizing adaptive polishing and compensating for the pressure fluctuation caused by the irregular edge. The vision sensor monitors the cutting and polishing status of the steel plate in real time and feeds back the position, shape and quality data to the control system to dynamically adjust the cutting and polishing path and pressure to ensure processing accuracy and consistency. S4: During the grinding process, the fan is started simultaneously. Its air inlet sucks up the debris and dust through the through hole on the lower surface of the cleaning frame. The debris after being sucked up is transported to the subsequent processing equipment through the air outlet pipe. After the grinding is completed, the fan is turned off, and the electric guide rail moves the steel plate to the bottom of the cleaning plate. The flexible cleaning sponge wipes and cleans the residual debris on the surface of the steel plate. S5: When it is necessary to press the steel plate, the electric guide rail continues to drive the steel plate to move. When the support tube moves to the rack side and the gear of the support frame is about to mesh with the rack, the electromagnetic brake releases the lock on the support frame. After the gear meshes with the rack, it drives the support frame to deflect 180 degrees on the support tube, so that the steel plate on the electric adsorption table is precisely positioned directly above the lower mold. The pressing electric push rod is started to drive the lower mold to rise to the preset distance. The vacuum adsorption system is turned off, and the steel plate falls into the lower mold cavity. The electric guide rail drives the support tube to reset. The pressing electric push rod continues to push the lower mold to rise and close with the upper mold to press, so that the steel plate is formed into a preset curved steel shell in the mold cavity. S6; After the steel shell is formed, the pressing electric push rod drives the lower mold to descend, and the worker removes the steel shell from the lower mold cavity. The above steps are repeated to process the next steel plate.

[0026] The beneficial effects of this invention are as follows: 1. By setting up a transportation mechanism, the steel plate is transported. The support tube can be moved by the guide rail slider. The support frame and the arc-shaped limiting groove of the support tube are slidably connected to limit the rotation of the support frame and prevent excessive rotation. The electric adsorption table uses a vacuum adsorption system to perform non-contact adsorption and fixation of the steel plate, ensuring that the steel plate is stable and does not shift during transportation. This avoids scratches or indentations on the surface of the steel plate caused by traditional clamps. It is also suitable for steel plates of different sizes and shapes, with strong versatility. The brake disc of the electromagnetic brake is fixedly connected to the rotating rod of the support frame by fastening bolts. It is used to accurately position and lock the rotation angle of the support frame, ensuring that the support frame will not rotate unexpectedly during processing. This solves the technical problem in the existing technology that steel plates are usually fixed by clamps, pressure plates or robotic arms. However, during mechanical clamping, the clamps are in direct contact with the surface of the steel plate, which can easily produce surface defects such as scratches and indentations, affecting the quality of subsequent processing.

[0027] 2. By setting up a processing mechanism, the steel plate is processed. The extension and retraction of the moving electric push rod drives the moving frame to move on the guide rail. The moving motor drives the moving screw to rotate. The moving screw is threadedly connected to the adjusting frame, driving it to move on the guide rail. The extension and retraction of the lifting electric push rod drives the moving frame to rise and fall on the moving frame. The processing motor drives the cutting screw to rotate, causing the cutting frame to rise and fall, which in turn drives the laser instrument housing to rise and fall synchronously, so as to cut the steel plate according to the preset path. The vision sensor monitors the cutting and grinding status of the steel plate in real time and feeds the image data back to the control system to dynamically adjust the cutting path and grinding pressure. The threads of the grinding screw and the cutting screw have the same direction and are connected by a thread. The gear meshing causes the rotation directions to be opposite. Therefore, when the cutting screw rotates clockwise, the cutting frame descends, while the grinding screw rotates counterclockwise, the grinding frame rises, and vice versa. This allows the cutting and grinding processes to be performed alternately. The support rod is fixedly installed with a spring inside the grinding roller, which returns to its original position after retraction. This allows the flexible grinding layer, which is fixedly bonded to the support rod, to automatically adjust the pressure according to the irregular shape of the steel plate edge, ensuring uniform grinding and avoiding over-grinding or under-grinding. This solves the technical problem in the prior art where rigid grinding tools are difficult to adapt to the curved shape of the steel plate during the grinding process after cutting, which easily leads to uneven grinding, leaving scratches or dents and affecting the surface finish.

[0028] 3. A pressing mechanism is used to press the cleaned steel plate to form a curved steel shell. The air inlet of the blower is fixedly connected to the cleaning frame via a hose. Air is drawn from the through-hole of the cleaning frame to create a negative pressure area. Metal shavings and dust generated during the grinding process are sucked into the cleaning frame and transported to the air inlet of the blower through the hose. The blower then transports the sucked-in shavings to the subsequent processing equipment through the air outlet pipe. Multiple bolt holes are provided on the cleaning plate to adjust the installation height of the flexible cleaning sponge according to the thickness of the steel plate. This allows the sponge to thoroughly wipe the surface and surrounding area of ​​the steel plate during its movement, removing residual shavings. The rack and pinion mesh with the gears of the support frame, driving the support... The support frame deflects within the support tube, and the extension and retraction of the pressing electric push rod can drive the lower mold to rise and fall. When the steel plate is directly below the lower mold, the pressing electric push rod can drive the lower mold to a suitable height, so that after the electric adsorption table releases its adsorption, the steel plate accurately falls into the mold cavity of the lower mold, preventing the steel plate from shifting during the descent due to excessive distance. Both the lower and upper molds can be fixed and installed with bolts for easy replacement. The shape of the mold cavity can be customized according to requirements to adapt to the processing of different curved steel shells. This solves the technical problem in the existing technology where grinding debris generated during the grinding process remains on the surface of the steel plate, which leads to poor contact between the mold and the steel plate, thus affecting the accuracy and effect of pressing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figures 1-16 A processing device for curved steel shells includes a frame 1 with an electric guide rail, and also includes a transport mechanism, a processing mechanism and a pressing mechanism installed in the frame 1.

[0033] like Figure 2-3 As shown, a transport mechanism is provided for transporting the steel plate.

The support frame 21 is slidably connected to the arc-shaped limiting groove of the support tube 2 to limit its rotation and prevent excessive rotation of the support frame 21.

[0035] Specifically, to ensure that the support frame 21 does not rotate unexpectedly during processing and to improve processing accuracy and safety, the electric adsorption table 3 is fixedly installed on the upper surface of the support plate of the support frame 21 by bolts.

It is also suitable for steel plates of different sizes and shapes, with strong versatility. The support tube 2 is fixedly installed to the electromagnetic brake 31 for fixation. The brake disc of the electromagnetic brake 31 is fixedly connected to the rotating rod of the support frame 21 by fastening bolts, which is used to accurately position and lock the rotation angle of the support frame 21, ensuring that the support frame 21 does not rotate unexpectedly during processing and improving processing accuracy and safety.

[0036] like Figure 4-9 As shown, a processing mechanism is provided for processing the steel plate. The processing mechanism is located inside the top of the frame 1 and processes the steel plate. The processing mechanism includes an adjustment component and a processing component. The adjustment component includes a moving frame 54. The movement of the moving frame 54 drives the processing component to move. The processing component includes a grinding roller 74. The rotation of the grinding roller 74 grinds the cut edges of the steel plate.

[0037] Specifically, in order to adjust the X-axis position of the processed part, the adjustment component also includes a movable electric push rod 4. The movable electric push rod 4 is fixedly installed on the inner side wall of the top of the frame 1. A movable frame 41 is fixedly installed at one end of the telescopic rod of the movable electric push rod 4. The guide rail sliders at both ends of the movable frame 41 are connected to the top guide rail of the frame 1 by built-in rollers. The movable electric push rod 4 is fixedly installed to the frame 1. The telescopic rod of the movable electric push rod 4 is fixedly installed to the movable frame 41. The extension and retraction of the telescopic rod drives the movable frame 41 to move on the guide rail, so as to adjust the X-axis position of the processed part. The setting of the guide rail can ensure the stability of the movement of the movable frame 41.

[0038] Specifically, to adjust the Z-axis position of the machined part, a moving motor 5 is fixedly installed at one end of the moving frame 41.

A rotating connection ensures the stability of the output shaft rotation of the moving motor 5. The output shaft of the moving motor 5 is fixedly installed with the moving screw 51, driving the moving screw 51 to rotate. The moving screw 51 is rotatably connected to the moving frame 41 through a bearing, ensuring the stability of the rotation of the moving screw 51. The moving screw 51 is threadedly connected to the adjusting frame 52, driving it to rotate and move. However, since the guide rail slider of the adjusting frame 52 is rolledly connected to the guide rail of the moving frame 41 through the built-in roller, it is limited and only moves, so as to adjust the Y-axis position of the processed part. The adjusting frame 52 is fixedly installed with the lifting electric push rod 53, which drives it to move synchronously while being fixed. The telescopic rod of the lifting electric push rod 53 is fixedly installed with the moving frame 54. The extension and retraction of the telescopic rod drives the moving frame 54 to rise and fall on the moving frame 41, so as to adjust the Z-axis position of the processed part.

[0039] Specifically, in order to cut the steel plate along a preset path, the processing components also include a processing motor 6. The processing motor 6 is fixedly installed on the inner top wall of the movable frame 54. The output shaft of the processing motor 6 is rotatably connected to the inner side wall of the movable frame 54 through a bearing seat. A cutting screw 61 with gears is fixedly installed on the output shaft of the processing motor 6. The cutting screw 61 is rotatably connected to the inner bottom wall of the movable frame 54 through a bearing. A cutting frame 62 is threadedly connected to the outer surface of the cutting screw 61. One end of the cutting frame 62 is connected to the guide rail slider of the movable frame 54 through a built-in roller. A laser instrument housing 63 is fixedly installed on the lower surface of the cutting frame 62 by bolts. The laser instrument housing 63 is fixedly installed to the processing motor 6 through the movable frame 54. The output shaft of the processing motor 6 is rotatably connected to the moving frame 54 through a bearing seat to ensure the stability of the rotation of the output shaft of the processing motor 6. The output shaft of the processing motor 6 is fixedly installed with the cutting screw 61 to drive its rotation. The cutting screw 61 is rotatably connected to the moving frame 54 through a bearing to ensure the stability of the rotation of the cutting screw 61. The cutting screw 61 is threadedly connected to the cutting frame 62 to drive its rotation and lifting. However, since the guide rail slider at one end of the cutting frame 62 is rolledly connected to the guide rail of the moving frame 54 through a built-in roller, it is limited to only lift and lower. The cutting frame 62 is fixedly installed with the laser instrument housing 63 by bolts to drive its synchronous lifting and lowering so as to cut the steel plate along a preset path.

[0040] Specifically, in order for the flexible grinding layer 76 to automatically adjust the pressure according to the irregular shape of the steel plate edge, a vision sensor 7 is fixedly installed on the lower surface of the moving frame 54. A grinding screw 71 with gears is rotatably connected to the inner wall of the moving frame 54 via a bearing. The gear of the grinding screw 71 meshes with the gear of the cutting screw 61. The threads of the grinding screw 71 and the cutting screw 61 have the same direction of rotation. A grinding frame 72 is threadedly connected to the outer surface of the grinding screw 71. One end of the grinding frame 72 has a guide rail slider. The grinding frame 72 is connected to the guide rail of the moving frame 54 by the built-in rollers. The grinding motor 73 is fixedly installed on the inner top wall of the grinding frame 72. The output shaft of the grinding motor 73 is rotatably connected to the inner side wall of the grinding frame 72 through the bearing seat. The output shaft of the grinding motor 73 is fixedly installed on one end of the grinding roller 74. A support rod 75 is slidably inserted into the groove of the grinding roller 74. One end of the support rod 75 is fixedly installed with the spring in the groove of the grinding roller 74. A flexible grinding layer 76 is fixedly bonded to the outer surface of the support rod 75. The moving frame 54 is fixedly installed with the vision sensor 7 to monitor the cutting and grinding status of the steel plate in real time, feeding image data back to the control system to dynamically adjust the cutting path and grinding pressure. The moving frame 54 is rotatably connected to the grinding screw 71 via bearings to ensure its rotational stability. The gears of the grinding screw 71 mesh with the gears of the cutting screw 61, causing them to rotate synchronously. Since the threads of the grinding screw 71 and the cutting screw 61 have the same direction, and the gear meshing causes them to rotate in opposite directions, when the cutting screw 61 rotates clockwise, the cutting frame 62 descends, while the grinding screw 71 rotates counterclockwise, the grinding frame 72 rises, and vice versa. This allows the cutting and grinding processes to be performed alternately. The grinding screw 71 is threadedly connected to the grinding frame 72, driving its rotation and lifting. However, because the guide rail slider at one end of the grinding frame 72 is rolled to the guide rail of the moving frame 54 via built-in rollers, the grinding frame 72 is also affected. The grinding frame 72 is fixedly installed to the grinding motor 73, which simultaneously drives the grinding frame to move up and down synchronously. The grinding motor 73 is fixedly installed to the grinding roller 74, which drives the roller to rotate. The support rod 75 is slidably inserted into the grinding roller 74, which drives the roller to rotate without affecting its extension and retraction. The support rod 75 is fixedly installed to the spring inside the grinding roller 74, which resets the roller after it retracts. This allows the flexible grinding layer 76, which is fixedly bonded to the support rod 75, to automatically adjust the pressure according to the irregular shape of the steel plate edge, ensuring uniform grinding and avoiding over-grinding or under-grinding. The flexible grinding layer 76 uses high-elasticity polyurethane or nitrile rubber as the base material, and a layer of silicon carbide or alumina abrasive is bonded to its surface. The abrasive particle size is selected according to the processing requirements to ensure grinding efficiency and surface quality. The adhesive can be epoxy resin or polyurethane adhesive to ensure a firm bond between the abrasive layer and the base material.

[0041] like Figure 10-16 As shown, in order to press the cleaned steel plate to form a curved steel shell, a pressing mechanism is provided. The pressing mechanism is located inside the bottom end of the frame 1 and presses the cleaned steel plate to form a curved steel shell. The pressing mechanism includes a cleaning component and a pressing component. The cleaning component includes a flexible cleaning sponge 84. The flexible cleaning sponge 84 achieves comprehensive wiping by closely adhering to the surface and surrounding area of ​​the steel plate. The pressing component includes a lower mold 92 and an upper mold 93. After the lower mold 92 moves, it closes and presses with the upper mold 93 to form the steel plate into a preset curved steel shell in the mold cavity.

[0042] Specifically, in order to thoroughly wipe the surface and surrounding area of ​​the steel plate and remove residual debris, the cleaning components also include a cleaning frame 8 with through holes. The cleaning frame 8 is fixedly installed on the lower surface of the outer support plate of the movable frame 54 by bolts. A fan 81 is fixedly installed on the outer side of the frame 1. The air inlet of the fan 81 is fixedly connected to the outer surface of the cleaning frame 8 through a flexible hose, and the air outlet of the fan 81 is fixedly connected to an air outlet pipe 82. A cleaning plate 83 with multiple bolt holes is fixedly installed in the outer groove of the frame 1 by bolts. A flexible cleaning sponge 84 is fixedly installed on the outer surface of the cleaning plate 83 by bolts. The cleaning frame 8 is fixedly installed to the movable frame 54 by bolts, which facilitates disassembly while fixing it. The cleaning frame 8 has a U-shaped structure, and its lower ring surface has through holes. The air inlet of the fan 81 is connected to... The cleaning frame 8 is fixedly connected to the hose, and air is drawn from the through hole of the cleaning frame 8 to form a negative pressure area. Metal shavings and dust generated during the grinding process are sucked into the cleaning frame 8 and transported to the air inlet of the blower 81 through the hose. The blower 81 transports the sucked-in shavings through the air outlet pipe 82 to subsequent processing equipment, such as dust collectors and filtration systems, to achieve centralized processing and recycling of shavings. The frame 1 and the cleaning plate 83 are fixedly installed with bolts. The cleaning plate 83 is fixedly installed with the flexible cleaning sponge 84 with bolts, which facilitates disassembly while fixing it. The cleaning plate 83 has multiple bolt holes to adjust the installation height of the flexible cleaning sponge 84 on the cleaning plate 83 according to the thickness of the steel plate. Thus, during the movement of the steel plate, the sponge wipes the surface and surrounding area of ​​the steel plate thoroughly to remove residual shavings.

[0043] Specifically, to prevent the steel plate from shifting during the falling process due to excessive distance, the pressing component also includes a rack 9. The rack 9 is fixedly installed on the inner side wall of the frame 1 by bolts. The rack 9 meshes with the gear of the support frame 21. A pressing electric push rod 91 is fixedly installed on the inner bottom wall of the frame 1. One end of the telescopic rod of the pressing electric push rod 91 is fixedly installed on the lower surface of the lower mold 92. The outer surface of the support rod of the lower mold 92 is slidably inserted into the groove of the inner bottom wall of the frame 1. The upper mold 93 is fixedly installed on the inner top wall of the frame 1. The rack 9 is fixedly installed to the frame 1 by bolts. The rack 9 meshes with the gear of the support frame 21, causing the support frame 21 to rotate within the support tube 2. The installation position and length of the rack 9 need to be set according to the actual working conditions to ensure that after the support frame 21 rotates 180 degrees, the steel plate on the electric adsorption table 3 is directly above the mold cavity of the lower mold 92. The rack 91 is fixedly installed to the pressing electric push rod 91 via the frame 1. The lower mold 92 is fixedly installed via the telescopic rod of the pressing electric push rod 91, and the extension and retraction of the telescopic rod can drive the lower mold 92. 2. Lifting and lowering: When the steel plate is directly below the lower mold 92, the pressing electric push rod 91 can drive the lower mold 92 to a suitable height. After the electric adsorption table 3 releases the adsorption, the steel plate accurately falls into the mold cavity of the lower mold 92, preventing the steel plate from shifting during the fall due to excessive distance, thus improving positioning accuracy. The upper mold 93 is fixedly installed to the frame 1 for fixation. Both the lower mold 92 and the upper mold 93 can be fixed by bolts for easy replacement. The shape of the mold cavity can be customized according to requirements to adapt to the processing of different curved steel shells.

[0044] like Figures 1-16 As shown, the processing method of the curved steel shell processing device proposed in this invention includes the following steps: S1: When it is necessary to transport the steel plate, the staff places the cleaned steel plate on the electric adsorption table 3, starts the vacuum adsorption system of the electric adsorption table 3 to adsorb and fix the steel plate, and then starts the electric guide rail of the frame 1 to drive the support tube 2 and its upper structure to move along the guide rail. When the steel plate is transported to the bottom of the processing mechanism, the electric guide rail is turned off. S2: When steel plate cutting is required, the processing motor 6 inside the moving frame 54 is started, driving the cutting screw 61 to rotate clockwise. Since the cutting screw 61 and the grinding screw 71 rotate in the same direction, the cutting screw 61 causes the grinding screw 71 to rotate counterclockwise through gear transmission. At this time, the cutting screw 61 drives the threaded cutting frame 62 to descend along the guide rail, while the grinding screw 71 drives the threaded grinding frame 72 to rise along the guide rail. The descent of the cutting frame 62 causes the laser instrument housing 63 to descend synchronously to the cutting position. When the X-axis position of the laser instrument housing 63 needs to be adjusted, the moving electric push rod 4 is started, and its telescopic rod moves... The moving frame 41 is moved. When the Y-axis position of the laser housing 63 needs to be adjusted, the moving motor 5 is started to drive the moving screw 51 to rotate, thereby driving the adjustment frame 52, which is threaded to it, to move along the guide rail. When the Z-axis position of the laser housing 63 needs to be adjusted, the lifting electric push rod 53 is started. The extension and retraction of its telescopic rod drives the moving frame 54 to rise and fall, thereby driving the laser housing 63 inside the moving frame 54 to adjust its position so that it can cut the steel plate according to the preset curve path. The fragments produced by cutting fall naturally below the frame 1 because the surface area of ​​the cut steel plate is still larger than that of the electric adsorption table 3. S3: When the cut steel plate needs to be polished, the processing motor 6 is started to drive the cutting screw 61 to rotate counterclockwise, causing the cutting frame 62 to rise and the polishing frame 72 to fall. The position adjustment program of the polishing roller 74 is consistent with the adjustment program of the laser instrument housing 63. When the polishing roller 74 is adjusted to the appropriate position and the flexible polishing layer 76 on it contacts the cutting edge of the steel plate, the polishing motor 73 is started to drive the polishing roller 74 to rotate. The polishing roller 74 drives the flexible polishing layer 76 to rotate synchronously through the support rod 75, thereby polishing the edge of the steel plate. During the polishing process, the support rod 75 pushes the flexible polishing layer 76 to always fit the edge of the steel plate under the action of the spring force, realizing adaptive polishing and compensating for the pressure fluctuation caused by the irregular edge. The vision sensor 7 monitors the cutting and polishing status of the steel plate in real time and feeds back the position, shape and quality data to the control system to dynamically adjust the cutting and polishing path and pressure to ensure processing accuracy and consistency. S4: During the grinding process, the blower 81 is started simultaneously. Its air inlet sucks up the debris and dust through the through hole on the lower surface of the cleaning frame 8. The debris after being sucked up is transported to the subsequent processing equipment through the air outlet pipe 82. After the grinding is completed, the blower 81 is turned off. The electric guide rail drives the steel plate to move to the bottom of the cleaning plate 83. The flexible cleaning sponge 84 wipes and cleans the residual debris on the surface of the steel plate. S5: When it is necessary to press the steel plate, the electric guide rail continues to drive the steel plate to move. When the support tube 2 moves to the side of the rack 9 and the gear of the support frame 21 is about to mesh with the rack 9, the electromagnetic brake 31 releases the lock on the support frame 21. After the gear meshes with the rack 9, it drives the support frame 21 to deflect 180 degrees on the support tube 2, so that the steel plate on the electric adsorption table 3 is precisely positioned above the lower mold 92. The pressing electric push rod 91 is started to drive the lower mold 92 to rise to the preset distance. The vacuum adsorption system is turned off, and the steel plate falls into the mold cavity of the lower mold 92. The electric guide rail drives the support tube 2 to reset. The pressing electric push rod 91 continues to push the lower mold 92 to rise and close and press with the upper mold 93, so that the steel plate is formed into a preset curved steel shell in the mold cavity. S6; After the steel shell is formed, the pressing electric push rod 91 drives the lower mold 92 to descend. The worker removes the steel shell from the mold cavity of the lower mold 92 and repeats the above steps to process the next steel plate.

When the steel plate is transported to the bottom of the processing mechanism, the electric guide rail will be turned off. S2: When it is necessary to cut the steel plate, start the processing motor (6) in the moving frame (54) to drive the cutting screw (61) to rotate clockwise. Since the cutting screw (61) and the grinding screw (71) rotate in the same direction, the cutting screw (61) causes the grinding screw (71) to rotate counterclockwise through gear transmission. At this time, the cutting screw (61) drives the cutting frame (62) connected to it to descend along the guide rail, and the grinding screw (71) drives the grinding frame (72) connected to it to rise along the guide rail. The cutting frame (62) descends and drives the laser instrument housing (63) to descend synchronously to the cutting station. When it is necessary to adjust the X-axis position of the laser instrument housing (63), start the moving electric push rod (4), whose telescopic rod The movement of the moving frame (41) causes the moving frame (41) to move. When the Y-axis position of the laser housing (63) needs to be adjusted, the moving motor (5) is started to drive the moving screw (51) to rotate, thereby driving the adjustment frame (52) connected to it to move along the guide rail. When the Z-axis position of the laser housing (63) needs to be adjusted, the lifting electric push rod (53) is started. The extension and retraction of its telescopic rod causes the moving frame (54) to rise and fall, thereby driving the laser housing (63) inside the moving frame (54) to adjust its position so that it can cut the steel plate according to the preset curve path. The fragments generated by the cutting fall naturally to the bottom of the frame (1) because the surface area of ​​the cut steel plate is still larger than that of the electric adsorption table (3). S3: When it is necessary to grind the cut steel plate, start the processing motor (6) to drive the cutting screw (61) to rotate counterclockwise, so that the cutting frame (62) rises and the grinding frame (72) falls.

When the grinding roller (74) is adjusted to a suitable position and the flexible grinding layer (76) on it contacts the cutting edge of the steel plate, start the grinding motor (73) to drive the grinding roller (74) to rotate. The grinding roller (74) passes through The support rod (75) drives the flexible grinding layer (76) to rotate synchronously, thereby grinding the edge of the steel plate. During the grinding process, the support rod (75) pushes the flexible grinding layer (76) to always fit the edge of the steel plate under the action of the spring force, realizing adaptive grinding and compensating for the pressure fluctuation caused by the irregular edge.

S4: During the grinding process, the blower (81) is started simultaneously. Its air inlet hose sucks up the debris and dust through the through hole on the lower surface of the cleaning frame (8). The debris after suction is transported to the subsequent processing equipment through the air outlet pipe (82). After the grinding is completed, the blower (81) is turned off. The electric guide rail drives the steel plate to move to the bottom of the cleaning plate (83). The flexible cleaning sponge (84) wipes and cleans the residual debris on the surface of the steel plate. S5: When it is necessary to press the steel plate, the electric guide rail continues to drive the steel plate to move. When the support tube (2) moves to the side of the rack (9) and the gear of the support frame (21) is about to mesh with the rack (9), the electromagnetic brake (31) releases the lock on the support frame (21). After the gear meshes with the rack (9), it drives the support frame (21) to deflect 180 degrees on the support tube (2), so that the steel plate on the electric adsorption table (3) is accurately positioned directly above the lower mold (92). The pressing electric push rod (91) is started to drive the lower mold (92) to rise to the preset distance. The vacuum adsorption system is turned off, and the steel plate falls into the mold cavity of the lower mold (92). The electric guide rail drives the support tube (2) to reset.
