Description

Technical Field

[0001] The invention relates to the technical field of honeycomb panel extrusion flanging, and more specifically, to an extrusion flanging device for a metal honeycomb composite panel and a working method thereof. Background Art

[0002] Metal honeycomb composite panel is a lightweight and high-strength building material, widely used in architectural decoration, aerospace and other fields. It consists of two layers of thin metal plates and a metal honeycomb core in the middle, which are compounded under high temperature and high pressure with a specific adhesive.

[0003] Among the two layers of thin metal plates, in order to avoid the need for subsequent edge sealing of the honeycomb panel, one of the thin metal plates needs to be bent and flanging. The thin metal plates are divided into circular metal plates and square metal plates, and the existing circular metal plate extrusion flanging device performs extrusion flanging through a mold of a specific shape and size.

[0004] Due to the limitations of die extrusion flanging, circular metal plates of different diameters cannot be extruded and flanging. The limitations of the die mean that it can only process plates of a specific size, which limits the processing range and flexibility. In order to accommodate plates of different sizes, it may be necessary to design and manufacture multiple sets of dies, increasing production costs. Each time the die is changed to accommodate plates of different sizes, additional setup and adjustment time will be added, reducing production efficiency.

[0005] Because the metal plate is too thin, before the thin metal plate is extruded and flanging, the thin metal plate is squeezed during transportation, which will cause unevenness in the middle of some thin metal plates. If the thickness of the metal plate is inconsistent, the material in some areas may be more susceptible to plastic deformation during the flanging process, thereby forming a bulge in the middle area. During the flanging process, if the pressure distribution is uneven, it may also cause excessive accumulation of materials in certain areas, thereby forming a bulge in the middle area. The unevenness in the middle will affect the subsequent installation of the metal honeycomb core.

[0006] Therefore, it is necessary to design an extrusion flanging device that can flanging and shaping metal honeycomb panels of different diameters to improve the above-mentioned technical problems. Summary of the invention

[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0059] For example, see Figure 1-12 The present invention provides the following technical solutions: an extrusion flanging device for a metal honeycomb composite panel, comprising a working box 1, a transmission mechanism 2 is provided on the upper side of the working box 1, a turning mechanism 8 is provided on the upper side of the transmission mechanism 2, a flanging mechanism 4 and an indentation mechanism 3 are provided on both sides of the transmission mechanism 2, a limiting mechanism 5 is provided on the upper side of the flanging mechanism 4, a camera 6 is provided on one side of the limiting mechanism 5, a controller 7 is provided on one side of the camera 6, and a shaping mechanism 9 is provided on one side of the controller 7.

[0060] Specifically, the transmission mechanism 2 is used to transmit the circular metal plate to different working areas for processing, the indentation mechanism 3 is used to indent the position of the circular metal plate that needs to be flanging, the flipping mechanism 8 is used to flip and rotate the circular metal plate, the flanging mechanism 4 is used to extrude and flanging the flipped and rotated circular metal plate, the limiting mechanism 5 is used to limit the circular metal plate that is being flanging, the shaping mechanism 9 is used to shape the flanging circular metal plate, and the camera 6 is used to take images of the flanging circular metal plate.

[0061] See also Figure 2 The transmission mechanism 2 includes a base 21, which is fixedly connected to the upper side of the work box 1. The two sides of the upper side of the base 21 are respectively fixedly connected with slide rails 25. A servo motor 22 is fixedly connected to one side of the base 21 and a screw rod 23 is fixedly connected to the output end. The other end of the screw rod 23 is connected to the bearing of the base 21. The outer ball bearing of the screw rod 23 is connected to a slide seat 24, and the slide seat 24 is slidably connected to the slide rail 25.

[0062] Specifically, the rotation of the output end of the servo motor 22 is used to control the slide 24 to slide along the slide rail 25. When the output end of the servo motor 22 rotates clockwise, the slide 24 slides to the left along the slide rail 25. When the output end of the servo motor 22 rotates counterclockwise, the slide 24 slides to the right along the slide rail 25.

[0063] See also Figure 3 The indentation mechanism 3 includes a first transmission box 31, which is fixedly connected to the upper side of the working box 1, and a first hydraulic cylinder 32 is fixedly connected to the upper side of the first transmission box 31, and a first slider 35 is fixedly connected to the output end of the first hydraulic cylinder 32, and the first slider 35 is slidably connected to the first transmission box 31, and a first motor 33 is fixedly connected to one side of the first slider 35, and the output end of the first motor 33 passes through the first slider 35 and the first transmission box 31 and is fixedly connected to a first roller 37, and a first pressure ring 36 is fixedly connected to the outer side of the first roller 37, and a second motor 34 is fixedly connected to one side of the first transmission box 31, and the output end of the second motor 34 passes through the first transmission box 31 and is fixedly connected to a second roller 38, and a second pressure ring 39 is fixedly connected to the outer side of the second roller 38.

[0064] Specifically, the rotation of the output end of the first motor 33 is used to control the rotation of the first roller 37, thereby controlling the rotation of the first pressure ring 36 to indent the upper part of the circular metal plate. The rotation of the output end of the second motor 34 is used to control the rotation of the second roller 38, thereby controlling the rotation of the second pressure ring 39 to indent the lower part of the circular metal plate. The extension and retraction of the output end of the first hydraulic cylinder 32 is used to control the up and down movement of the first pressure ring 36, thereby performing indentation work on circular metal plates of different thicknesses.

[0065] When the circular metal plate needs to be indented, the output end of the servo motor 22 rotates counterclockwise, and the slide 24 slides to the right along the slide rail 25 until the edge of the circular metal plate is located between the first pressure ring 36 and the second pressure ring 39. The output end of the first hydraulic cylinder 32 extends to control the first pressure ring 36 to press the top of the circular metal plate. While the flipping mechanism 8 controls the flipping of the circular metal plate, the output ends of the first motor 33 and the second motor 34 rotate to control the rotation of the first pressure ring 36 and the second pressure ring 39 to perform indentation on the circular metal plate.

[0066] By providing the indentation mechanism 3, the circular metal plate is pre-indented before flanging, so that during the subsequent flanging, the flanging mechanism 4 can perform flanging along the indentation track, effectively preventing the circular metal plate from being offset during flanging, and achieving the effect of high flanging accuracy and high efficiency.

[0067] In the second embodiment, due to the limitation of the die extrusion flanging, circular metal plates of different diameters cannot be extruded and flanging can not be performed. The limitation of the die means that it can only process plates of a specific size, which limits the processing range and flexibility. In order to accommodate plates of different sizes, it may be necessary to design and manufacture multiple sets of die, which increases production costs. Each time the die is changed to accommodate plates of different sizes, additional setup and adjustment time will be added, which reduces production efficiency.

[0068] See also Figure 4 The flanging mechanism 4 includes a second transmission box 41, which is fixedly connected to the upper side of the working box 1, a second hydraulic cylinder 42 is fixedly connected to the upper side of the second transmission box 41 and a second slider 43 is fixedly connected to the output end of the second hydraulic cylinder 42, the second slider 43 is slidably connected to the second transmission box 41 and a third motor 44 is fixedly connected to one side, the output end of the third motor 44 passes through the second slider 43 and the second transmission box 41 and is fixedly connected to a third roller 45, a fourth motor 46 is fixedly connected to one side of the second transmission box 41, and the output end of the fourth motor 46 passes through the second transmission box 41 and is fixedly connected to a fourth roller 47.

[0069] Specifically, the rotation of the output end of the third motor 44 is used to control the rotation of the third roller 45, the rotation of the output end of the fourth motor 46 is used to control the rotation of the fourth roller 47, and the extension and retraction of the output end of the second hydraulic cylinder 42 is used to control the up and down movement of the third roller 45, so that the third roller 45 presses the top of the circular metal plates of different thicknesses.

[0070] See also Figure 5The limiting mechanism 5 includes a positioning frame 52, the positioning frame 52 is fixedly connected to the upper side of the second transmission box 41, the upper side of the second transmission box 41 is fixedly connected to the third hydraulic cylinder 51, the output end of the third hydraulic cylinder 51 passes through the positioning frame 52 and is fixedly connected to the fourth hydraulic cylinder 53, and the output end of the fourth hydraulic cylinder 53 is fixedly connected to the pressure plate 54.

[0071] Specifically, the extension and retraction of the output end of the fourth hydraulic cylinder 53 is used to control the pressure plate 54 to move closer to or away from the flipped circular metal plate, thereby limiting it and preventing the circular metal plate with a large diameter from tilting down without supporting force, resulting in uneven subsequent flanging. The extension of the output end of the third hydraulic cylinder 51 is used to control the pressure plate 54 to move up and down, thereby limiting the circular metal plates of different diameters.

[0072] See also Figure 6 and Figure 7 The flipping mechanism 8 includes an L-shaped plate 82, which is fixedly connected to the upper side of the slide seat 24. A first arc-shaped guide groove 85 is provided on one side of the L-shaped plate 82. A first cylinder 84 is fixedly connected to one side of the L-shaped plate 82. A first connecting rod 81 is hinged on the output end of the first cylinder 84. A first sliding column 83 is hinged on the other end of the first connecting rod 81. The first sliding column 83 is slidably connected to the first arc-shaped guide groove 85. A second connecting rod 86 is hinged on the outer side of the first sliding column 83. A rotating shaft 87 is fixedly connected to the other end of the second connecting rod 86. The rotating shaft 87 is connected to the L-shaped plate 82 bearing. A rotating assembly 88 is provided on the other end of the rotating shaft 87.

[0073] Specifically, the extension and retraction of the output end of the first cylinder 84 is used to control the second connecting rod 86 to rotate along the direction of the first arc-shaped guide groove 85. When the output end of the first cylinder 84 is fully extended, the second connecting rod 86 rotates ninety degrees with the rotating shaft 87 as the axis point, thereby controlling the rotating component 88 to rotate ninety degrees, and then controlling the circular metal plate on the rotating component 88 to flip ninety degrees.

[0074] See also Figure 8 The rotating component 88 includes a fixed column 883, which is fixedly connected to the other end of the rotating shaft 87. The other end of the fixed column 883 is fixedly connected to a fixed seat 885. One side of the fixed seat 885 is fixedly connected to a fifth motor 884. The output end of the fifth motor 884 is fixedly connected to a gear 882. The upper bearing of the fixed seat 885 is connected to an electromagnetic disk 881. The inner wall of the electromagnetic disk 881 is evenly fixedly connected with a plurality of teeth. The electromagnetic disk 881 is meshingly connected to the gear 882.

[0075] Specifically, the rotation of the output end of the fifth motor 884 is used to control the gear 882 to rotate, and the gear 882 rotates and controls the electromagnetic disk 881 to rotate.

[0076] When it is necessary to flanging circular metal plates of different diameters, the electromagnetic disk 881 absorbs the circular metal plate, and when the circular metal plate is rotated clockwise by the output end of the servo motor 22, the slide 24 slides to the left along the slide rail 25 until the indentation of the circular metal plate is located between the third roller 45 and the fourth roller 47, the slide 24 stops moving, and the output end of the second hydraulic cylinder 42 extends until the third roller 45 completely presses the top of the circular metal plate, the output ends of the third motor 44 and the fourth motor 46 rotate to control the third roller 45 and the fourth roller 47 to rotate backward, the output end of the first cylinder 84 is fully extended, and the second connecting rod 86 rotates ninety degrees with the rotating shaft 87 as the axis point. At this time, the circular metal plate is in a vertical state.

[0077] The output end of the fourth hydraulic cylinder 53 extends out to control the pressure plate 54 to be close to the circular metal plate, thereby limiting it. In the initial state, the output end of the third hydraulic cylinder 51 is completely retracted. At this time, the pressure plate 54 is limited on the edge of the circular metal plate. The output end of the fifth motor 884 rotates to control the gear 882 to rotate. When the gear 882 rotates, it controls the electromagnetic disk 881 to rotate, thereby controlling the circular metal plate to rotate. The third roller 45 and the fourth roller 47 begin to flanging the circular metal plate.

[0078] While the circular metal plate rotates, the output end of the third hydraulic cylinder 51 extends at a uniform speed, so that the pressure plate 54 gradually moves away from the edge of the circular metal plate until the circular metal plate rotates half a circle. At this time, the pressure plate 54 moves inward to avoid the flange of the circular metal plate to prevent it from colliding with the pressure plate 54 after the flange is completed. When the circular metal plate rotates one circle, the flange of the circular metal plate is completed, and the output end of the second hydraulic cylinder 42 retracts. At this time, the circular metal plate is no longer pressed, the output end of the first cylinder 84 is completely retracted, the circular metal plate returns to its position, and the third motor 44, the fourth motor 46 and the fifth motor 884 are turned off.

[0079] The edge of the circular metal plate is pressed and rotated by controlling the third roller 45 and the fourth roller 47, and the first cylinder 84 controls the circular metal plate to rotate ninety degrees to bend the edge. At the same time, the fifth motor 884 controls the circular metal plate to rotate so that its entire edge is flanged, so that circular metal plates of different diameters can be flanged, achieving a strong adaptability to the flanging of the circular metal plate. The pressure plate 54 limits the upper part of the circular metal plate while flanging the circular metal plate, effectively preventing the upper part of the circular metal plate with a large diameter from tilting, and the pressure plate 54 moves synchronously while limiting the circular metal plate, effectively preventing the flange from colliding with the pressure plate 54 after the circular metal plate is rotated halfway, thereby causing damage to the flange of the circular metal plate.

[0080] In the third embodiment, since the metal plate is too thin, before the thin metal plate is extruded and flanged, the thin metal plate is squeezed during transportation, which will cause unevenness in the middle of some thin metal plates. If the thickness of the metal plate is inconsistent, the material in some areas may be more susceptible to plastic deformation during the flanging process, thereby forming a bulge in the middle area. During the flanging process, if the pressure distribution is uneven, it may also cause excessive accumulation of material in some areas, thereby forming a bulge in the middle area. The unevenness in the middle will affect the subsequent installation of the metal honeycomb core.

[0081] The shooting end of the camera 6 is aimed directly downward, and a database is provided inside the controller 7, wherein identification photos of circular metal plates with different diameters and different raised shadow sizes are provided inside the database.

[0082] Specifically, the camera 6 is used to capture images of the top of the round metal plate with flanged edges, and convert the captured images into electrical signals and transmit them to the controller 7. A database is provided inside the controller 7, and identification photos of round metal plates with different diameters and different sizes of raised shadows are provided inside the database. When the controller 7 receives the photos sent by the camera 6, it will compare them with the identification photos of the round metal plates with different sizes of raised shadows in the internal database, pre-identify the raised condition of the round metal plate, and take photos based on the obtained round metal plate to distinguish the raised condition into three conditions: no raised condition, slight raised condition, and severe raised condition. When an object with a raised portion is photographed or observed from above, the higher the height of the raised portion, the larger the shadow area formed below it will usually be, and the more obvious the shape will be. Then, it will be compared with the identification photos of the round metal plates with different diameters in the internal database to identify the diameter value of the round metal plate, and take photos based on the obtained surface of the round metal plate to distinguish the diameter size of the round metal plate into three diameter specifications: large diameter, medium diameter, and small diameter.

[0083] When the output end of the sixth motor 95 is not rotating, the second slide column 963 is located at the initial end of the second arc-shaped guide groove 962, and the pressure plate 967 is not expanded. When the output end of the sixth motor 95 rotates ninety degrees clockwise, the second slide column 963 slides to the middle of the second arc-shaped guide groove 962, and the pressure plate 967 expands half. When the output end of the sixth motor 95 rotates one hundred and eighty degrees clockwise, the second slide column 963 slides to the end of the second arc-shaped guide groove 962, and the pressure plate 967 expands completely.

[0084] When the camera 6 captures that there is no shadow in the middle of the circular metal plate, it is determined that there is no bulge in the middle of the circular metal plate. This circular metal plate does not need to be flattened and shaped in the middle, and only the flanging position needs to be shaped. In the initial state, the output end of the dual-axis cylinder 973 is in a fully extended state. When the flanging position needs to be shaped, the output end of the second cylinder 91 extends to control the second pressure column 975 and the first pressure column 974 to move downward until the flanging of the circular metal plate is located between the second pressure column 975 and the first pressure column 974. The output end of the dual-axis cylinder 973 begins to shrink until the distance between the second pressure column 975 and the first pressure column 974 is equal to the flanging thickness of the circular metal plate. The output end of the fifth motor 884 rotates to control the circular metal plate to rotate one circle. While the circular metal plate rotates, the second pressure column 975 and the first pressure column 974 extrude and shape the flanging of the circular metal plate.

[0085] When the camera 6 captures that the shadow in the middle of the circular metal plate is too large, it is judged that the middle of the circular metal plate is seriously bulging, and the circular metal plate is seriously deformed. It is difficult to reshape the middle of the circular metal plate by extrusion, so it is directly judged as scrapped and recycled.

[0086] When the camera 6 captures that the shadow in the middle of the circular metal plate is too small, it is judged that the middle of the circular metal plate is slightly convex, and the middle of the circular metal plate is slightly deformed, and it needs to be reshaped. After the processing is completed, the flange of the circular metal plate is reshaped. The flange shaping process has been described in detail above and will not be repeated here.

[0087] When the camera 6 captures that the diameter of the circular metal plate is smaller than the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a small-diameter metal plate, and the second cylinder 91 controls the pressure plate 967 to move downward to flatten the middle area of ​​the circular metal plate.

[0088] When the camera 6 captures that the diameter of the circular metal plate is equal to the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a medium diameter metal plate, the second cylinder 91 controls the pressure plate 967 to move downward, close to the top of the circular metal plate, the output end of the sixth motor 95 rotates ninety degrees clockwise, the second slide column 963 slides to the middle of the second arc-shaped guide groove 962, the pressure plate 967 expands half, the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the middle area of ​​the circular metal plate, the second cylinder 91 controls the pressure plate 967 to lift, the output end of the fifth motor 884 rotates to control the circular metal plate to rotate thirty degrees, and the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the area pressed by the middle position of the circular metal plate.

[0089] When the camera 6 captures that the diameter of the circular metal plate is greater than the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a large-diameter metal plate, and the second cylinder 91 controls the pressure plate 967 to move downward and close to the top of the circular metal plate. The output end of the sixth motor 95 rotates one hundred and eighty degrees clockwise, and the second slide column 963 slides to the end of the second arc-shaped guide groove 962. The pressure plate 967 is fully expanded, and the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the middle area of ​​the circular metal plate. The second cylinder 91 controls the pressure plate 967 to lift up, and the output end of the fifth motor 884 rotates to control the circular metal plate to rotate thirty degrees. The second cylinder 91 controls the pressure plate 967 to move downward again to flatten the area pressed by the middle position of the circular metal plate.

[0090] See also Figure 9-11 The shaping mechanism 9 includes a second cylinder 91, which is fixedly connected to the upper side of the positioning frame 52, a sixth motor 95 is fixedly connected to the output end of the second cylinder 91, a third slider 93 is fixedly connected to one side of the sixth motor 95, a first guide block 94 is fixedly connected to the lower side of the positioning frame 52, the third slider 93 and the first guide block 94 are slidably connected, a rotating shaft 92 is fixedly connected to the output end of the sixth motor 95, a pressure plate adjusting assembly 96 is provided at the other end of the rotating shaft 92, and a straightening assembly 97 is provided at one side of the pressure plate adjusting assembly 96.

[0091] Specifically, the extension and retraction of the output end of the second cylinder 91 is used to control the upward and downward movement of the pressure plate adjustment assembly 96 and the straightening assembly 97, and the rotation of the output end of the sixth motor 95 is used to control the rotation of the pressure plate adjustment assembly 96 and the straightening assembly 97.

[0092] The pressure plate adjustment assembly 96 includes a turntable 961, which is fixedly connected to the outer side of the rotating shaft 92. Five second arc-shaped guide grooves 962 are evenly arranged inside the turntable 961. The other end of the rotating shaft 92 is bearing-connected to a guide sliding block 966. The guide sliding block 966 is slidingly connected to a slide plate 964 inside. The upper side of the slide plate 964 is fixedly connected to a second sliding column 963. The second sliding column 963 is slidingly connected to the second arc-shaped guide groove 962. The other end of the slide plate 964 is fixedly connected to an arc block 965. The lower side of the arc block 965 is fixedly connected to a pressure plate 967.

[0093] Specifically, when the output end of the second cylinder 91 is fully extended, the pressure plate 967 is pressed on top of the circular metal plate.

[0094] When circular expansion is required, the output end of the sixth motor 95 starts to rotate clockwise, the turntable 961 rotates clockwise, and the second slide column 963 slides outward along the second arc-shaped guide groove 962, indirectly controlling the slide plate 964 to move along the guide slide block 966, thereby controlling the pressure plate 967 to move outward for expansion.

[0095] When the circle needs to be reduced, the output end of the sixth motor 95 starts to rotate counterclockwise, the turntable 961 rotates counterclockwise, and the second slide column 963 slides inward along the second arc-shaped guide groove 962, indirectly controlling the slide plate 964 to move along the guide slide block 966, thereby controlling the pressure plate 967 to move inward for reduction.

[0096] See also Fig.12 The straightening assembly 97 includes a connecting rod 971, which is rotatably connected to the outer side of the rotating shaft 92. The lower side of the connecting rod 971 is slidably connected to a double-axis cylinder 973. One side of the double-axis cylinder 973 is fixedly connected to a connecting block 972. The other end of the connecting block 972 is fixedly connected to one of the arc blocks 965. The two output ends of the double-axis cylinder 973 are respectively fixedly connected to a first positioning plate and a second positioning plate. The lower sides of the first positioning plate and the second positioning plate are respectively bearing-connected to a second pressure column 975 and a first pressure column 974.

[0097] Specifically, the extension and retraction of the output end of the dual-axis cylinder 973 is used to control the second pressure column 975 and the first pressure column 974 to move closer to or farther away from each other, thereby extruding and shaping the flanges of circular metal plates of different thicknesses. When the pressure plate 967 moves inward or outward, it will indirectly control the synchronous movement of the straightening assembly 97.

[0098] The camera 6 takes images of circular metal plates with different diameters and different raised shadow sizes, and the controller 7 makes a judgment to determine whether the circular metal plate needs to be shaped, thereby preventing unnecessary shaping work. During shaping, the pressure plate 967 automatically moves according to the diameter of the circular metal plate, transforms into a shape that adapts to the diameter of the circular metal plate, and then flattens it, thereby achieving an adaptive flattening effect. The second pressure column 975 and the first pressure column 974 can adapt to the flanging of circular metal plates of different thicknesses by moving closer to and further away from each other, thereby shaping the flanging of circular metal plates of different thicknesses, thereby achieving a high leveling efficiency and high accuracy, making subsequent gluing and installation more convenient.

[0099] Embodiment 4, a working method of an extrusion flanging device for a metal honeycomb composite panel, according to the extrusion flanging device for a metal honeycomb composite panel described above, comprises the following steps:

[0100] S1: The robot places the circular metal plate on the transmission end of the transmission mechanism 2, and the transmission mechanism 2 transmits the circular metal plate to the working area of ​​the creasing mechanism 3.

[0101] S2: The indentation mechanism 3 performs indentation work on the position of the circular metal plate that needs to be flanging.

[0102] S3: The transport mechanism 2 transports the circular metal plate to the working area of ​​the flanging mechanism 4, and the flipping mechanism 8 flips the circular metal plate and controls it to rotate.

[0103] S4: While rotating, the limiting mechanism 5 positions the upper area of ​​the circular metal plate, and the flanging mechanism 4 performs flanging processing on the indentation position of the circular metal plate.

[0104] The more specific steps of S4 are, S41: when it is necessary to flanging circular metal plates of different diameters, the electromagnetic disk 881 absorbs the circular metal plate, and when the circular metal plate is rotated clockwise by the output end of the servo motor 22, the slide 24 slides to the left along the slide rail 25 until the indentation of the circular metal plate is located between the third roller 45 and the fourth roller 47, the slide 24 stops moving, and the output end of the second hydraulic cylinder 42 extends until the third roller 45 completely presses the top of the circular metal plate, the output ends of the third motor 44 and the fourth motor 46 rotate to control the third roller 45 and the fourth roller 47 to rotate backward, the output end of the first cylinder 84 is fully extended, and the second connecting rod 86 rotates ninety degrees with the rotating shaft 87 as the axis point, and the circular metal plate is in a vertical state.

[0105] S42: The output end of the fourth hydraulic cylinder 53 extends out to control the pressure plate 54 to be close to the circular metal plate, thereby limiting it. In the initial state, the output end of the third hydraulic cylinder 51 is completely retracted. At this time, the pressure plate 54 is limited on the edge of the circular metal plate. The output end of the fifth motor 884 rotates to control the gear 882 to rotate. When the gear 882 rotates, it controls the electromagnetic disk 881 to rotate, thereby controlling the circular metal plate to rotate. The third roller 45 and the fourth roller 47 begin to flanging the circular metal plate.

[0106] S43: While the circular metal plate is rotating, the output end of the third hydraulic cylinder 51 extends at a uniform speed, so that the pressure plate 54 gradually moves away from the edge of the circular metal plate until the circular metal plate rotates half a circle. At this time, the pressure plate 54 moves inward to avoid the flange of the circular metal plate to prevent it from colliding with the pressure plate 54 after the flange is completed. When the circular metal plate rotates one circle, the flange of the circular metal plate is completed, and the output end of the second hydraulic cylinder 42 retracts. At this time, the circular metal plate is no longer pressed, and the output end of the first cylinder 84 is completely retracted, the circular metal plate returns to its position, and the third motor 44, the fourth motor 46 and the fifth motor 884 are turned off.

[0107] S5: After the flanging is completed, the camera 6 takes a photo of the circular metal plate, and compares the taken photos to determine the height and diameter of the protrusion in the middle of the circular metal plate.

[0108] The more specific step of S5 is, S51: the camera 6 takes an image of the top of the round metal plate with the flanged edge, and converts the taken photo into an electrical signal to transmit to the controller 7. The controller 7 is provided with a database inside, and the database is provided with identification photos of round metal plates with different diameters and different convex shadow sizes. When the controller 7 receives the photo sent by the camera 6, it will compare it with the identification photos of the round metal plates with different convex shadow sizes in the internal database, pre-identify the convex condition of the round metal plate, and take photos based on the obtained round metal plate, and distinguish the convex condition into three conditions: no convexity, slight convexity, and severe convexity. When an object with a convex part is photographed or observed from above, the higher the height of the convex part, the larger the shadow area formed below it is usually, and the more obvious the shape is. Then, it is compared with the identification photos of the round metal plates with different diameters in the internal database to identify the diameter value of the round metal plate, and take photos based on the obtained surface of the round metal plate to distinguish the diameter size of the round metal plate into three diameter specifications: large diameter, medium diameter, and small diameter.

[0109] S52: When the output end of the sixth motor 95 is not rotating, the second slide column 963 is located at the initial end of the second arc-shaped guide groove 962, and the pressure plate 967 is not expanded. When the output end of the sixth motor 95 rotates ninety degrees clockwise, the second slide column 963 slides to the middle of the second arc-shaped guide groove 962, and the pressure plate 967 expands half. When the output end of the sixth motor 95 rotates one hundred and eighty degrees clockwise, the second slide column 963 slides to the end of the second arc-shaped guide groove 962, and the pressure plate 967 expands completely.

[0110] S6: The controller 7 controls the shaping mechanism 9 to shape the convex area and the flange area of ​​the circular metal plate to different degrees according to the height and diameter of the convexity in the middle of the circular metal plate.

[0111] The more specific step of S6 is, S61: when the camera 6 captures that there is no shadow in the middle of the circular metal plate, it is determined that there is no bulge in the middle of the circular metal plate. This circular metal plate does not need to be flattened and shaped in the middle, and only the flanging position needs to be shaped. In the initial state, the output end of the dual-axis cylinder 973 is in a fully extended state. When the flanging position needs to be shaped, the output end of the second cylinder 91 extends to control the second pressure column 975 and the first pressure column 974 to move downward until the flanging of the circular metal plate is located between the second pressure column 975 and the first pressure column 974. The output end of the dual-axis cylinder 973 begins to shrink until the distance between the second pressure column 975 and the first pressure column 974 is equal to the flanging thickness of the circular metal plate. The output end of the fifth motor 884 rotates to control the circular metal plate to rotate one circle. While the circular metal plate rotates, the second pressure column 975 and the first pressure column 974 extrude and shape the flanging of the circular metal plate.

[0112] S62: When the camera 6 captures a shadow in the middle of the circular metal plate that is too large, it is determined that the circular metal plate is seriously bulging in the middle. The circular metal plate is seriously deformed and it is difficult to reshape the middle of the circular metal plate by extrusion. It is directly determined to be scrapped and recycled.

[0113] S63: When the camera 6 captures that the shadow in the middle of the circular metal plate is too small, it is determined that the middle of the circular metal plate is slightly convex. The middle of the circular metal plate is slightly deformed and needs to be reshaped. After the processing is completed, the flange of the circular metal plate is reshaped. The flange shaping process has been described in detail above and will not be repeated here.

[0114] S64: When the camera 6 captures that the diameter of the circular metal plate is smaller than the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a small-diameter metal plate, and the second cylinder 91 controls the pressure plate 967 to move downward to flatten the middle area of ​​the circular metal plate.

[0115] S65: When the camera 6 captures that the diameter of the circular metal plate is equal to the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a medium diameter metal plate, the second cylinder 91 controls the pressure plate 967 to move downward, close to the top of the circular metal plate, the output end of the sixth motor 95 rotates ninety degrees clockwise, the second slide column 963 slides to the middle of the second arc-shaped guide groove 962, the pressure plate 967 expands half, the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the middle area of ​​the circular metal plate, the second cylinder 91 controls the pressure plate 967 to lift, the output end of the fifth motor 884 rotates to control the circular metal plate to rotate thirty degrees, the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the area pressed by the middle position of the circular metal plate.

[0116] S66: When the camera 6 captures that the diameter of the circular metal plate is greater than the diameter of the electromagnetic disk 881, the controller 7 determines that the circular metal plate is a large-diameter metal plate, and the second cylinder 91 controls the pressure plate 967 to move downward and close to the top of the circular metal plate. The output end of the sixth motor 95 rotates one hundred and eighty degrees clockwise, and the second slide column 963 slides to the end of the second arc-shaped guide groove 962. The pressure plate 967 is fully expanded, and the second cylinder 91 controls the pressure plate 967 to move downward again to flatten the middle area of ​​the circular metal plate. The second cylinder 91 controls the pressure plate 967 to lift up, and the output end of the fifth motor 884 rotates to control the circular metal plate to rotate thirty degrees. The second cylinder 91 controls the pressure plate 967 to move downward again to flatten the area pressed by the middle position of the circular metal plate.
