Abstract

The present invention is applicable to the technical field of trimming and shaping of honeycomb aluminum plates, and provides a trimming and shaping device for aluminum plates and a working method thereof, including a conveying component and a cleaning component, a positioning component and a trimming component installed on the top of the conveying component, wherein the conveying component includes a first bracket and a second bracket connected to one side of the first bracket. The device solves the problem that during the trimming and shaping process of the honeycomb aluminum plate, the plate itself is prone to vibration during trimming, and its internal honeycomb hole structure easily causes the folded edge to bend when trimming to the honeycomb hole position, resulting in uneven edges and affecting the trimming effect. The device achieves the effect of using a clamping claw cylinder to move the end of an active clamping plate to the middle of the side of the aluminum plate and insert a shaping block, and then the cylinder drives the clamping plate to separate and shape the side deformation, thereby effectively improving the trimming and shaping effect of the honeycomb aluminum plate, and is particularly suitable for shaping at the honeycomb hole position.

Description

Technical Field

[0001] The present invention relates to the technical field of trimming and shaping of aluminum plates, and more specifically, to a trimming and shaping device for aluminum plates and a working method thereof. Background Art

[0002] Honeycomb aluminum sheet is a composite material with many advantages. It is widely used in architectural decoration, aerospace, transportation and other fields. When processing honeycomb aluminum sheet, in order to ensure product quality, suitable for subsequent processing and meet application requirements, it is necessary to use trimming and shaping devices for processing.

[0003] When the existing trimming and shaping device is in use, a conveying mechanism is used to convey the honeycomb aluminum sheet, and then two trimming knives are used to perform bilateral trimming. After that, the honeycomb aluminum sheet continues to be conveyed and is trimmed twice by trimming knives in the other two directions, thereby finally achieving the purpose of trimming and shaping. However, this method will leave a large amount of debris residue. For this reason, the staff has improved the existing method, that is, adding an air blowing device at the position of the trimming knife to blow off some of the debris during the trimming process, thereby ensuring the neatness of the honeycomb aluminum sheet.

[0004] However, the honeycomb aluminum sheet adopts the method of trimming both sides at the same time during the trimming process. However, since the sheet itself will vibrate during trimming and there are a large number of honeycomb holes inside, it is easy to cause the folding edge to bend when trimming to the honeycomb holes. This situation will further cause the edge to be uneven, affecting the overall quality of the trimming effect. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a trimming and shaping device for aluminum plates and a working method thereof.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a trimming and shaping device for aluminum plates, comprising a conveying assembly and a cleaning assembly, a positioning assembly and a trimming assembly installed on the top of the conveying assembly, the conveying assembly comprising a first bracket and a second bracket connected to one side of the first bracket, and the tops of the first bracket and the second bracket are both rotatably connected to multiple transmission rollers.

[0007] There are two groups of cleaning components, and the two groups of cleaning components are symmetrically installed on the top of the side of the first bracket away from the second bracket. A steering component is provided at the bottom of the first bracket. The steering component penetrates the first bracket upward and extends between the two groups of cleaning components. Both groups of cleaning components include a collecting mechanism installed on the top of the first bracket and a cleaning mechanism arranged inside the collecting mechanism.

[0008] There are two groups of positioning components, and the two groups of positioning components are symmetrically installed on the top of the second bracket.

A clamping cylinder is installed on the top of the two first movable seats, and an L-shaped plate is connected to the end of the piston rod of the clamping cylinder. A shaping mechanism is slidably connected to the top of each guide rail and located between the two first movable seats.

[0009] The trimming assembly is arranged above the two groups of positioning assemblies, and a grabbing assembly is arranged on the top of the trimming assembly.

[0010] The present invention is further configured as follows: the steering assembly includes four lifting cylinders arranged at the bottom of the first bracket and a frame connected to the top of the lifting cylinder piston rod, the top of the frame is rotatably connected to a turntable, and the top of the turntable is rotatably connected to multiple conveying rollers.

[0011] The present invention is further configured as follows: a cylinder is installed on one side of the frame, a servo motor is installed on one end of the cylinder, the output end of the servo motor extends to the interior of the cylinder and is connected to a driving wheel, the interior of the frame is rotatably connected to a driven wheel, and the driven wheel and the driving wheel are meshed.

[0012] By adopting the above technical solution, the honeycomb aluminum plate is lifted by driving the frame upward as a whole through the lifting cylinder, and then the driving wheel is driven to rotate by the servo motor, and the driven wheel rotates through meshing and drives the turntable to rotate, thereby adjusting the angle of the conveying roller and the honeycomb aluminum plate, so as to facilitate the cleaning component to clean the impurities and debris on the side of the honeycomb aluminum plate.

[0013] The present invention is further configured as follows: the two groups of collecting mechanisms each include a fixing frame installed on the top of the first bracket, a driving motor is installed on the side wall of the fixing frame, the output end of the driving motor is connected to a rotating shaft, the outer side wall of the rotating shaft is connected to a swing plate, the side wall of the swing plate is connected to a collecting bucket, and a frame is provided at the opening of the collecting bucket.

[0014] The present invention is further configured as follows: the cleaning mechanism comprises a driving rod rotatably connected to the inside of the collecting bucket and a threaded groove arranged on the outer side wall of the driving rod, and cleaning columns are evenly arranged on the thread lines of the threaded groove.

[0015] By adopting the above technical solution, when the honeycomb aluminum plate reaches the top of the first bracket, both ends of the honeycomb aluminum plate are exposed outside the first bracket, the two collecting buckets swing to a vertical state and clamp the honeycomb aluminum plate, and the two sides of the honeycomb aluminum plate extend into the interior of the collecting bucket, and the external drive drives the driving rod and the threaded groove to rotate, and the threaded groove and the cleaning column cooperate to clean the impurities, and the collecting bucket is connected to the external exhaust device, and the air inside the collecting bucket is extracted by the exhaust device, and the air forms a flow direction. This process can discharge the impurities and debris remaining in the honeycomb holes.

[0016] The present invention is further configured as follows: a wedge-shaped portion and a bearing platform are provided on a side of the L-shaped plate away from the clamping cylinder, and the bearing platform is located between the wedge-shaped portion and the side wall of the L-shaped plate.

[0017] The present invention is further configured as follows: the shaping mechanism includes a second movable seat slidably connected to the top of the corresponding guide rail and a shaping cylinder installed on the top of the second movable seat, the piston rod of the shaping cylinder and the piston rod of the corresponding clamping cylinder are oriented in the same direction, a clamping cylinder is installed at the end of the piston rod of the shaping cylinder, two active clamping plates are connected to the output end of the clamping cylinder, and driven clamping plates are connected to the top and bottom of the clamping cylinder, one of the driven clamping plates is arranged corresponding to the active clamping plate, and a plurality of shaping blocks are equidistantly provided on the opposite side of the two active clamping plates.

[0018] By adopting the above technical solution, the clamping cylinder drives the corresponding L-shaped plate to move, and the wedge-shaped part on the side wall of the L-shaped plate shovels up the side of the honeycomb aluminum plate. As the L-shaped plate continues to approach the honeycomb aluminum plate, the side of the honeycomb aluminum plate slides along the inclined surface of the wedge-shaped part and finally reaches the position of the supporting platform for placement. At this time, the honeycomb aluminum plate is lifted to a certain height and positioned, and the four L-shaped plates cooperate to clamp and position the side of the honeycomb aluminum plate. The honeycomb aluminum plate is in a suspended state, which facilitates subsequent trimming operations and avoids the situation where the honeycomb aluminum plate cannot be trimmed due to the bonding and conveying components.

[0019] The present invention is further configured as follows: the trimming assembly includes two placement racks symmetrically installed on the top of the second bracket, the tops of the two placement racks are each installed with a guide rail, the tops of the guide rails are slidably connected with two groups of first electric slide rails, the side walls of the two groups of the first electric slide rails are slidably connected with second electric slide rails, a trimming motor is installed on the side walls of the second electric slide rails, the output end of the trimming motor is connected with a trimming knife, and the trimming knife is vertically arranged.

[0020] By adopting the above technical scheme, when the first electric slide rail moves on the guide rail, the movement of the second electric slide rail, the trimming motor and the trimming knife is adjusted. When the second electric slide rail is running, the slide seat of the first electric slide rail stops moving, causing the slide seat of the second electric slide rail to remain stationary, and the parts of the second electric slide rail except the slide seat move downward, thereby adjusting the height of the trimming motor and the trimming knife. The trimming motor drives the trimming knife to rotate, and then the trimming knife performs trimming operations on the honeycomb aluminum plate. In this process, the trimming knife performs trimming operations on one edge of the honeycomb aluminum plate by adjusting the position of the first electric slide rail and the second electric slide rail, and the two trimming knives can simultaneously perform trimming operations on the two side edges of the honeycomb aluminum plate.

[0021] The present invention is further configured as follows: the grabbing assembly includes a grabbing electric slide rail slidably connected to the top of the two sets of guide rails and a slide table slidably connected to the side wall of the grabbing electric slide rail, the side wall of the slide table is vertically connected to the vertical electric slide rail, the bottom of the vertical electric slide rail is equipped with an electric turntable, and the bottom of the electric turntable is equipped with multiple suction cups.

[0022] By adopting the above technical scheme, after the honeycomb aluminum plate is trimmed by the trimming assembly, the grabbing electric slide rail moves on the guide rail and the slide moves on the side wall of the grabbing electric slide rail to adjust the position of the suction cup. After the adjustment, the vertical electric slide rail is used to drive the electric turntable and the suction cup to move downward, so that the suction cup grabs and lifts the top surface of the honeycomb aluminum plate, and the L-shaped plate is away from the honeycomb aluminum plate. The electric turntable drives the suction cup and the honeycomb aluminum plate to rotate 90 degrees, thereby adjusting the direction of the honeycomb aluminum plate to facilitate subsequent shaping operations.

[0023] The trimming and shaping working method for honeycomb aluminum sheet, using the trimming and shaping device for aluminum sheet as described above, comprises the following steps:

[0024] S1. The staff places the honeycomb aluminum sheet to be processed on the top of the first bracket, and transports it through the transmission roller on the top of the first bracket. The honeycomb aluminum sheet is transported to the top of the second bracket and placed.

[0025] S2. Then the clamping cylinders on the two sets of positioning components are operated, and the clamping cylinders push the L-shaped plate to move to clamp and position the honeycomb aluminum plate, and then the trimming components are used to trim the two side edges of the honeycomb aluminum plate.

[0026] S3. After the honeycomb aluminum sheet is trimmed by the trimming assembly, the grabbing assembly grabs and limits the top surface of the honeycomb aluminum sheet, and the L-shaped plate is away from the honeycomb aluminum sheet. The grabbing assembly then places the honeycomb aluminum sheet and turns it 90 degrees, and then re-clamps and positions it by the L-shaped plate, and then uses the trimming assembly to trim the other two sides of the honeycomb aluminum sheet.

[0027] S4. After the trimming of the aluminum plate is completed, the first moving seat, the clamping cylinder and the L-shaped plate cooperate to slide on the guide rail, so that the L-shaped plates on the guide rail are separated from each other, and then the grabbing assembly grabs and lifts the aluminum plate again, and the side of the lifted aluminum plate is shaped by the shaping mechanism.

[0028] S5. After the trimming and shaping of the aluminum plate is completed, the honeycomb aluminum plate is re-placed on the top of the second bracket through the cooperation of the grabbing component and the trimming component, and then the transmission roller on the top of the second bracket sends the honeycomb aluminum plate to the top of the first bracket, and then the cleaning component is used to remove impurities from the two sides of the honeycomb aluminum plate, and then the steering component is used to control the honeycomb aluminum plate to rotate 90 degrees, and then the cleaning component is used to remove impurities from the other two sides of the honeycomb aluminum plate.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] (1) By setting a positioning component, the clamping cylinder drives the corresponding L-shaped plate to move, and the wedge-shaped part on the side wall of the L-shaped plate shovels up the side of the honeycomb aluminum plate. As the L-shaped plate continues to approach the honeycomb aluminum plate, the side of the honeycomb aluminum plate slides along the inclined surface of the wedge-shaped part and finally reaches the position of the supporting platform for placement. At this time, the honeycomb aluminum plate is lifted to a certain height for positioning, and the four L-shaped plates cooperate to clamp and position the side of the honeycomb aluminum plate. The honeycomb aluminum plate is in a suspended state, which facilitates the subsequent trimming operation and avoids the situation where the honeycomb aluminum plate cannot be trimmed due to the bonding of the conveying component.

[0031] (2) By setting up a grabbing component, after the honeycomb aluminum plate is trimmed by the trimming component, the grabbing electric slide rail moves on the guide rail and the slide moves on the side wall of the grabbing electric slide rail to adjust the position of the suction cup. After adjustment, the vertical electric slide rail is used to drive the electric turntable and the suction cup to move downward, so that the suction cup grabs and lifts the top surface of the honeycomb aluminum plate, and the L-shaped plate is away from the honeycomb aluminum plate. The electric turntable drives the suction cup and the honeycomb aluminum plate to rotate 90 degrees, thereby adjusting the direction of the honeycomb aluminum plate to facilitate subsequent shaping operations.

[0032] (3) The active clamping plates are driven by the clamping cylinder to approach each other, and the end of the active clamping plate is moved to the middle of the side of the aluminum plate. The end of the shaping block is inserted into the honeycomb hole on the side of the aluminum plate. Then, the clamping cylinder drives the two active clamping plates to move away from each other, so that the active clamping plate and the corresponding driven clamping plate cooperate to shape the deformed position of the side of the aluminum plate. This not only achieves the purpose of shaping the honeycomb aluminum plate, but also can shape the honeycomb hole position of the honeycomb aluminum plate, greatly improving the trimming and shaping effect of the honeycomb aluminum plate.

[0033] (4) When the honeycomb aluminum sheet reaches the top of the first bracket, both ends of the honeycomb aluminum sheet are exposed outside the first bracket, and the two collecting buckets swing to a vertical state and clamp the honeycomb aluminum sheet. The two sides of the honeycomb aluminum sheet extend into the interior of the collecting bucket, and the external drive drives the driving rod and the thread groove to rotate. The thread groove and the cleaning column cooperate to clean the impurities, and the collecting bucket is connected to the external exhaust device. The air inside the collecting bucket is extracted through the exhaust device, and the air forms a flow direction. This process can discharge the impurities and debris remaining in the honeycomb holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] 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.

[0054] 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.

[0055] See also Figure 1-11 , the present invention provides the following technical solutions:

[0056] Embodiment 1, a trimming and shaping device for aluminum plates, comprises a conveying assembly 1, the conveying assembly 1 is used to convey the honeycomb aluminum plates that need trimming and shaping, and the specific structure of the conveying assembly 1 is as follows:

[0057] See also Figure 1 and Figure 2The conveying assembly 1 includes a first bracket 11 and a second bracket 13 connected to one side of the first bracket 11. The tops of the first bracket 11 and the second bracket 13 are rotatably connected with multiple transmission rollers 12. The honeycomb aluminum sheet is horizontally conveyed by the transmission rollers 12 on the first bracket 11 and the second bracket 13, so that the honeycomb aluminum sheet can switch positions between the first bracket 11 and the second bracket 13.

[0058] See also Figure 1 and Fig.10 A trimming assembly 5 is installed on the top of the second bracket 13. The trimming assembly 5 is used to trim the conveyed honeycomb aluminum sheet. The specific structure of the trimming assembly 5 is as follows:

[0059] See also Figure 1 and Fig.10 The trimming assembly 5 includes two placement racks 51 symmetrically installed on the top of the second bracket 13, and guide rails 52 are installed on the top of the two placement racks 51. Two groups of first electric slide rails 53 are slidably connected to the top of the guide rails 52. The side walls of the two groups of first electric slide rails 53 are slidably connected to the second electric slide rails 54. A trimming motor 55 is installed on the side wall of the second electric slide rail 54. The output end of the trimming motor 55 is connected to a trimming knife 56, and the trimming knife 56 is vertically arranged. The first electric slide rail 53 and the second electric slide rail 54 are both stepper motor linear slide rail slide seat modules, that is, the screw rod in the linear slide rail is driven to rotate by the stepper motor, so that the slide seat slides inside the corresponding linear slide rail, and the first electric slide rail 53 and the second electric slide rail 54 are respectively installed with a driving mechanism between the guide rail 52, that is, the driving mechanism is composed of a driving motor and a gear, and a rack is arranged on the guide rail 52. When the driving motor drives the gear to rotate, the gear moves on the rack, thereby driving The corresponding first electric slide rail 53 or the second electric slide rail 54 moves, and the slide seat of the first electric slide rail 53 is connected to the slide seat of the second electric slide rail 54. When the first electric slide rail 53 moves on the guide rail 52, the second electric slide rail 54, the trimming motor 55 and the trimming knife 56 are adjusted to move. When the second electric slide rail 54 is running, the slide seat of the first electric slide rail 53 stops moving, causing the slide seat of the second electric slide rail 54 to remain stationary, and the parts of the second electric slide rail 54 except the slide seat move downward, thereby adjusting the height of the trimming motor 55 and the trimming knife 56. The trimming motor 55 drives the trimming knife 56 to rotate, thereby causing the trimming knife 56 to trim the honeycomb aluminum sheet. In this process, the trimming knife 56 trims one edge of the honeycomb aluminum sheet by coordinating the adjustment of the position of the first electric slide rail 53 and the second electric slide rail 54, and the two trimming knives 56 can cooperate to trim the two side edges of the honeycomb aluminum sheet at the same time.

[0060] In the second embodiment, when the existing trimming device is used to trim the honeycomb aluminum plate, since two sides are trimmed simultaneously, the honeycomb aluminum plate itself will vibrate, and there are a large number of honeycomb holes inside it. Therefore, when trimming to the honeycomb holes, it is easy to cause the folded edge to bend, which in turn causes the edge to be uneven, affecting the trimming effect.

[0061] To this end, two sets of positioning components 4 are symmetrically installed on the top of the second bracket 13. The positioning components 4 are used to clamp and position the honeycomb aluminum sheet and shape the side after trimming. The specific structure of the positioning components 4 is as follows:

[0062] The two positioning assemblies 4 each include a guide rail 41 mounted on the top of the second bracket 13 and two first movable seats 42 slidably connected to the top of the guide rail 41. A clamping cylinder 43 is mounted on the top of the two first movable seats 42. An L-shaped plate 45 is connected to the piston rod end of the clamping cylinder 43. A shaping mechanism 44 is slidably connected to the top of each guide rail 41 and located between the two first movable seats 42. A wedge-shaped portion 46 and a bearing platform 47 are provided on the side of the L-shaped plate 45 away from the clamping cylinder 43. The bearing platform 47 is located at Between the wedge-shaped portion 46 and the side wall of the L-shaped plate 45, a walking mechanism is arranged inside the first movable seat 42, that is, an electric drive wheel is arranged inside the first movable seat 42, so that the first movable seat 42 can move along the extension direction of the guide rail 41, and the clamping cylinder 43 is used to drive the corresponding L-shaped plate 45 to move, and the four L-shaped plates 45 cooperate to clamp and position the side of the honeycomb aluminum plate. The honeycomb aluminum plate is in a suspended state, which facilitates subsequent trimming operations and avoids the situation where the honeycomb aluminum plate is unable to be trimmed due to the bonding and conveying component 1.

[0063] Specifically, the clamping cylinders 43 on the two groups of positioning assemblies 4 are in operation, and the clamping cylinders 43 push the L-shaped plate 45 to move and clamp and position the honeycomb aluminum plate. During this process, the wedge-shaped portion 46 on the side wall of the L-shaped plate 45 shovels up the side edge of the honeycomb aluminum plate. As the L-shaped plate 45 continues to approach the honeycomb aluminum plate, the side edge of the honeycomb aluminum plate slides along the inclined surface of the wedge-shaped portion 46, and finally reaches the position of the supporting platform 47 for placement. At this time, the honeycomb aluminum plate is lifted to a certain height and positioned, and the first electric slide rail 53 slides on the guide rail 52, thereby adjusting the spacing between the two first electric slide rails 53, and the second electric slide rail 54, the trimming motor 55 and the trimming knife 56 move synchronously with the corresponding first electric slide rail 53, thereby adjusting the trimming position of the trimming knife 56 on the honeycomb aluminum plate, and then the second electric slide rail 54 drives the trimming motor 55 and the trimming knife 56 to move downward, and the trimming motor 55 drives the trimming knife 56 to rotate, causing the trimming knife 56 to cut and trim the honeycomb aluminum plate.

[0064] The top of the trimming assembly 5 is provided with a grabbing assembly 6, which includes a grabbing electric slide rail 61 slidably connected to the top of the two sets of guide rails 52 and a slide table 62 slidably connected to the side wall of the grabbing electric slide rail 61. The side wall of the slide table 62 is vertically connected to a vertical electric slide rail 63. The bottom of the vertical electric slide rail 63 is installed with an electric turntable 64. The bottom of the electric turntable 64 is installed with a plurality of suction cups 65. After the honeycomb aluminum sheet is trimmed by the trimming assembly 5, the grabbing electric slide rail 61 is placed on the guide rail 52. The moving and sliding table 62 moves and adjusts the position of the suction cup 65 while grabbing the side wall of the electric slide rail 61. After the adjustment, the vertical electric slide rail 63 is used to drive the electric turntable 64 and the suction cup 65 to move downward, so that the suction cup 65 grabs and lifts the top surface of the honeycomb aluminum plate, and the L-shaped plate 45 is away from the honeycomb aluminum plate. The electric turntable 64 drives the suction cup 65 and the honeycomb aluminum plate to rotate 90 degrees, and then re-clamps and positions them through the L-shaped plate 45, and then the trimming assembly 5 is used to trim the other two side edges of the honeycomb aluminum plate.

[0065] After the trimming of the aluminum plate is completed, the first moving seat 42, the clamping cylinder 43 and the L-shaped plate 45 cooperate to slide on the guide rail 41, so that the L-shaped plates 45 on the guide rail 41 are separated from each other, and then the grabbing assembly 6 grabs and lifts the aluminum plate again, and the side of the lifted aluminum plate is shaped by the shaping mechanism 44. The specific structure of the shaping mechanism 44 is as follows:

[0066] The shaping mechanism 44 includes a second moving seat 441 slidably connected to the top of the corresponding guide rail 41 and a shaping cylinder 442 installed on the top of the second moving seat 441. The piston rod of the shaping cylinder 442 is oriented in the same direction as the piston rod of the corresponding clamping cylinder 43. A clamping cylinder 443 is installed at the end of the piston rod of the shaping cylinder 442. The output end of the clamping cylinder 443 is connected to two active clamping plates 445. The top and bottom of the clamping cylinder 443 are both connected to driven clamping plates 444, one of which is corresponding to the active clamping plate 445. The two active clamping plates 445 are arranged in a corresponding manner. A plurality of shaping blocks 446 are equidistantly provided on one side opposite to the movable clamping plate 445. The structure of the second movable seat 441 is the same as that of the first movable seat 42, and the second movable seat 441 can also slide on the top of the guide rail 41. The second movable seat 441 drives the shaping cylinder 442 to move synchronously during the movement. The shaping cylinder 442 is used to drive the clamping claw cylinder 443, the two active clamping plates 445 and the driven clamping plate 444 to move synchronously. The active clamping plate 445 cooperates with the corresponding driven clamping plate 444 to clamp and shape the side of the honeycomb aluminum plate. The overall specific method is as follows:

[0067] After the trimming of the aluminum plate is completed, the first moving seat 42, the clamping cylinder 43 and the L-shaped plate 45 cooperate to slide on the guide rail 41, so that the L-shaped plates 45 on the guide rail 41 are moved away from each other, and then the grabbing assembly 6 grabs and lifts the aluminum plate again, and then the shaping cylinder 442 drives the clamping cylinder 443, the driven clamping plate 444 and the active clamping plate 445 to approach the side of the aluminum plate, and the two driven clamping plates 444 move to the top and bottom of the aluminum plate respectively. In this process, the active clamping plates 445 are driven to approach each other by the clamping cylinder 443, and the end of the active clamping plate 445 moves to the middle of the side of the aluminum plate, and the end of the shaping block 446 is inserted into the honeycomb hole on the side of the aluminum plate. Afterwards, the clamping claw cylinder 443 drives the two active clamps 445 to move away from each other, so that the active clamps 445 cooperate with the corresponding driven clamps 444 to reshape the deformed position of the side of the aluminum plate. After the two sides of the aluminum plate are shaped, the shaping mechanism 44 moves away from the aluminum plate, and then the grabbing component 6 drives the aluminum plate to rotate 90 degrees, and then the shaping operation is performed again through the shaping mechanism 44. This shaping method can adjust the folding deformation that appears at the honeycomb aluminum plate honeycomb hole position, and through the shaping block 446 extended into the honeycomb hole for shaping, not only the purpose of shaping the honeycomb aluminum plate is achieved, but also the honeycomb aluminum plate honeycomb hole position can be shaped, which greatly improves the trimming and shaping effect of the honeycomb aluminum plate.

[0068] Embodiment 3: After the honeycomb aluminum plate is trimmed and shaped, there are honeycomb holes inside it, so the impurities remaining after the trimming and shaping will accumulate in the honeycomb holes. If they are not treated specifically, the structural integrity and performance of the honeycomb aluminum plate will be affected.

[0069] To this end, a steering assembly 2 is provided at the bottom of the first bracket 11, and two groups of cleaning assemblies 3 are symmetrically installed on the top of the side of the first bracket 11 away from the second bracket 13. The steering assembly 2 is used to steer the honeycomb aluminum plate, and then switch the direction of the side of the honeycomb aluminum plate toward the two groups of cleaning assemblies 3, so that the two groups of cleaning assemblies 3 can clean the sides of the honeycomb aluminum plate from impurities and debris.

[0070] In this embodiment, the specific structure of the steering assembly 2 is as follows: the steering assembly 2 includes four lifting cylinders 21 arranged at the bottom of the first bracket 11 and a frame 22 connected to the top of the piston rod of the lifting cylinder 21. The top of the frame 22 is rotatably connected to a turntable 25, and the top of the turntable 25 is rotatably connected to multiple conveying rollers 26. The turntable 25 rotates inside the frame 22, thereby driving the multiple conveying rollers 26 to change their angles, and the lifting cylinder 21 is used to drive the frame 22, the turntable 25 and the conveying roller 26 to adjust the height. When the honeycomb aluminum plate returns to the top of the conveying roller 26, the lifting cylinder 21 drives the frame 22, the turntable 25 and the conveying roller 26 to rise and fall, thereby lifting the honeycomb aluminum plate. The lifted honeycomb aluminum plate rotates through the turntable 25 and the conveying roller 26, thereby adjusting the angle of the honeycomb aluminum plate in the horizontal direction, and finally adjusting the direction of the side of the honeycomb aluminum plate to facilitate the cleaning operation of the two groups of cleaning components 3. The rotation driving method of the turntable 25 is as follows:

[0071] A cylinder 23 is installed on one side of the frame 22, and a servo motor 24 is installed at one end of the cylinder 23. The output end of the servo motor 24 extends to the inside of the cylinder 23 and is connected to a driving wheel 28. The internal rotation of the frame 22 is connected to a driven wheel 27, and the driven wheel 27 and the driving wheel 28 are meshed with each other. The servo motor 24 is used to drive the driving wheel 28 to rotate. Since the driving wheel 28 and the driven wheel 27 are meshed with each other, when the driving wheel 28 rotates, it drives the driven wheel 27 to rotate, and then drives the turntable 25 to rotate in the horizontal direction, and finally adjusts the side direction of the honeycomb aluminum plate.

[0072] The specific structure of the cleaning component 3 is as follows:

[0073] The steering assembly 2 passes through the first bracket 11 upward and extends between the two groups of cleaning assemblies 3. The two groups of cleaning assemblies 3 include a collecting mechanism 31 installed on the top of the first bracket 11 and a cleaning mechanism 32 arranged inside the collecting mechanism 31. The collecting mechanism 31 is used to collect foreign debris, and the cleaning mechanism 32 sweeps away foreign debris remaining on the side of the honeycomb aluminum plate.

[0074] In this embodiment, the specific structure of the collecting mechanism 31 is as follows: the two groups of collecting mechanisms 31 both include a fixing frame 311 installed on the top of the first bracket 11, a driving motor 312 is installed on the side wall of the fixing frame 311, the output end of the driving motor 312 is connected to a rotating shaft 313, the outer side wall of the rotating shaft 313 is connected to a swing plate 314, the side wall of the swing plate 314 is connected to a collecting bucket 315, and a frame is provided at the opening of the collecting bucket 315, the driving motor 312 is used to drive the rotating shaft 313, the swing plate 314 and the collecting bucket 315 to swing, thereby adjusting the angle of the collecting bucket 315, because the width of the first bracket 11 is smaller than the width of the second bracket 13, so when the honeycomb aluminum plate reaches the top of the first bracket 11, the two ends of the honeycomb aluminum plate are exposed outside the first bracket 11, the two collecting buckets 315 swing to a vertical state and clamp the honeycomb aluminum plate, the two side edges of the honeycomb aluminum plate extend into the interior of the collecting bucket 315, and the collecting bucket 315 collects impurities and debris on the side edges of the honeycomb aluminum plate.

[0075] In this embodiment, the cleaning mechanism 32 includes a driving rod 321 rotatably connected to the inside of the collecting bucket 315 and a threaded groove 322 arranged on the outer wall of the driving rod 321, and cleaning columns 323 are evenly arranged on the thread line of the threaded groove 322. The external drive drives the driving rod 321 and the threaded groove 322 to rotate, and the threaded groove 322 and the cleaning column 323 cooperate to clean the impurities, and the collecting bucket 315 is connected to an external exhaust device, and the air inside the collecting bucket 315 is extracted by the exhaust device, and the air forms a flow direction. This process can discharge the impurities and debris remaining in the honeycomb holes.

[0076] And when the two sides are cleaned, the lifting cylinder 21 drives the frame 22 to move upward as a whole to lift the honeycomb aluminum plate, and then the servo motor 24 drives the driving wheel 28 to rotate, and the driven wheel 27 rotates through meshing and drives the turntable 25 to rotate, thereby adjusting the angle of the conveying roller 26 and the honeycomb aluminum plate. After the adjustment of the honeycomb aluminum plate, the cleaning component 3 is used to remove impurities from the other two sides of the honeycomb aluminum plate, thereby avoiding the impurities and debris remaining in the honeycomb holes to affect the structural integrity and performance of the honeycomb aluminum plate.

[0077] Embodiment 4, a trimming and shaping working method for a honeycomb aluminum sheet, using the trimming and shaping device for an aluminum sheet as described above, comprises the following steps:

During this process, the wedge-shaped portion 46 on the side wall of the L-shaped plate 45 shovels up the side of the honeycomb aluminum plate. As the L-shaped plate 45 continues to approach the honeycomb aluminum plate, the side of the honeycomb aluminum plate slides along the inclined surface of the wedge-shaped portion 46 and finally reaches the position of the supporting platform 47 for placement. At this time, the honeycomb aluminum plate is lifted to a certain height and positioned.

[0083] S3. After the honeycomb aluminum sheet is trimmed by the trimming assembly 5, the grabbing assembly 6 grabs and limits the top surface of the honeycomb aluminum sheet, and the L-shaped plate 45 is away from the honeycomb aluminum sheet.

[0086] S32, the electric turntable 64 drives the suction cup 65 and the honeycomb aluminum plate to rotate 90 degrees, and then re-clamps and positions them through the L-shaped plate 45, and then uses the trimming assembly 5 to trim the other two side edges of the honeycomb aluminum plate.

[0087] S4. After the trimming of the aluminum plate is completed, the first movable seat 42, the clamping cylinder 43 and the L-shaped plate 45 cooperate to slide on the guide rail 41, so that the L-shaped plates 45 on the guide rail 41 are separated from each other. Then the grabbing assembly 6 grabs the aluminum plate again and lifts it. The side edge of the lifted aluminum plate is shaped by the shaping mechanism 44.

In this process, the active clamping plates 445 are driven to approach each other by the clamping cylinder 443, and the end of the active clamping plate 445 moves to the middle of the side of the aluminum plate. The end of the shaping block 446 is inserted into the honeycomb hole on the side of the aluminum plate. Then, the clamping cylinder 443 drives the two active clamping plates 445 to move away from each other, so that the active clamping plate 445 cooperates with the corresponding driven clamping plate 444 to shape the deformation position of the side of the aluminum plate.

[0091] S43, after the two side edges of the aluminum plate are shaped, the shaping mechanism 44 moves away from the aluminum plate, and then the grabbing assembly 6 drives the aluminum plate to rotate 90 degrees, and then the shaping operation is performed again through the shaping mechanism 44.

[0092] S5. After the trimming and shaping of the aluminum plate is completed, the honeycomb aluminum plate is re-placed on the top of the second bracket 13 through the cooperation of the grabbing component 6 and the trimming component 5. Then the driving roller 12 on the top of the second bracket 13 sends the honeycomb aluminum plate to the top of the first bracket 11.
