A cover bracket is provided on one side surface of the support frame, a hanging component is provided on one side surface of the top of the cover bracket, and a rotating buckle is provided in the middle of one side surface of the fixing plate. However, foam aluminum boards require different sizes due to environmental requirements, and the existing device is not easy to cut foam aluminum boards to a fixed length. Utility Model Content

[0004] The purpose of this invention is to provide a foam aluminum board cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foam aluminum board cutting device, including a cutting worktable, two positioning grooves symmetrically opened on the top surface of the cutting worktable, a first guide rail being provided inside each positioning groove, two second guide rails symmetrically arranged above the cutting worktable, each second guide rail being slidably connected to the two first guide rails by a slider, and a first positioning plate being slidably connected to the surface of each second guide rail by a slider, the first positioning plate being in contact with the foam aluminum board.

[0006] Preferably, a fixing plate is fixedly connected to the opposite side of each of the second guide rails, and a first threaded rod is threadedly connected to the inside of each fixing plate through a threaded cylinder. The first threaded rod passes through the surface of the fixing plate and is rotatably connected to a rubber block. A limit groove is formed on the top surface of the cutting workbench, and the rubber block is inserted into the limit groove.

[0007] Preferably, a pointer is fixedly connected to one end of the second guide rail biased towards the saw blade, and a dimension table is engraved on the top surface of the cutting workbench at the position corresponding to the pointer.

[0008] Preferably, a pressure plate is provided above each of the first positioning plates, and a second threaded rod is threadedly connected to the inside of each pressure plate through a threaded cylinder. The second threaded rod passes through the surface of the pressure plate and is rotatably connected to the first positioning plate.

[0009] Preferably, the surface of the cutting workbench is symmetrically fixedly connected to two supports by bolts. A motor is mounted on the surface of one of the supports. The output shaft of the motor passes through the surface of the support and is fixedly connected to a lead screw. The end of the lead screw away from the motor is rotatably connected to the other support through a bearing. A second positioning plate is threadedly connected to the surface of the lead screw through a threaded cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model achieves rapid and accurate positioning of the cutting length of foam aluminum board through a dual guide rail system in conjunction with pointers and size charts. The friction locking mechanism between the rubber block and the limiting groove ensures the stability of the guide rail position during the cutting process, avoiding errors from manual measurement. The linkage design between the pressure plate and the second threaded rod further strengthens the fixation of the board, prevents displacement during cutting, and significantly improves processing accuracy and repeatability.

[0014] 2. This utility model solves the problem of wavy patterns caused by uneven manual pushing speed by using a motor-driven lead screw to move the first positioning plate at a uniform speed. The mechanical transmission ensures that the feeding speed of the foam aluminum board is consistent, which not only improves the flatness of the cutting surface, but also reduces the intensity of operation. It is especially suitable for batch processing scenarios, taking into account both efficiency and finished product quality.

[0015] 3. This utility model effectively captures the chips generated during cutting by integrating a chip guide shell, a vacuum pump, and a chip collection box into a closed chip suction system. This prevents aluminum powder from flying and polluting the environment or accumulating and affecting the precision of the equipment. The inclined chip guide shell design enhances the chip guiding efficiency, and the flexible hose enables centralized collection, which not only protects the health of operators but also facilitates subsequent cleaning and maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides a foam aluminum board cutting device, including a cutting workbench 1. Two positioning grooves are symmetrically formed on the top surface of the cutting workbench 1. A first guide rail 2 is installed inside each positioning groove. Two second guide rails 3 are symmetrically arranged above the cutting workbench 1. Each second guide rail 3 is slidably connected to the two first guide rails 2 via a slider. A first positioning plate 4 is slidably connected to the surface of each second guide rail 3 via a slider. The first positioning plate 4 is in contact with the foam aluminum board. A fixing plate 5 is fixedly connected to the opposite side of each second guide rail 3. A first threaded rod 6 is threadedly connected to the inside of each fixing plate 5 via a threaded cylinder. The first threaded rod 6 passes through the surface of the fixing plate 5 and is rotatably connected to a rubber block 7. A limit groove is formed on the top surface of the cutting workbench 1, and the rubber block 7 is inserted into the limit groove. A pointer 9 is fixedly connected to one end of the second guide rail 3 biased towards the saw blade side. The top surface of the cutting workbench 1 and the pointer 9 are aligned. The corresponding position is marked with a dimension table 8. When it is necessary to cut the foam aluminum board to a fixed length, place the foam aluminum board above the cutting workbench 1, and then apply force to the second guide rail 3 that is biased towards the saw blade. The second guide rail 3 slides on the surface of the first guide rail 2 through the slider. When the second guide rail 3 moves, the pointer 9 will move synchronously until the pointer 9 moves to the indicated position. By observing the number in the dimension table 8, the size to be cut is determined. Then, by rotating the first threaded rod 6, the rubber block 7 is inserted into the limiting groove. The friction between the rubber block 7 and the cutting workbench 1 is used to position the second guide rail 3. Then, the second guide rail 3 on the other side is moved so that the second guide rail 3 on the other side supports the foam aluminum board. Then, the second guide rail 3 on the other side is positioned to achieve the positioning of the foam aluminum board. Then, the first positioning plate 4 is pushed towards the saw blade to achieve the fixed-length cutting of the foam aluminum board.

[0024] In this embodiment, a pressure plate 10 is provided above each first positioning plate 4. Each pressure plate 10 is internally connected to a second threaded rod 11 via a threaded cylinder. The second threaded rod 11 passes through the surface of the pressure plate 10 and is rotatably connected to the first positioning plate 4. In order to prevent the foam aluminum board from tilting and moving due to the resistance of the saw blade when cutting, the second threaded rod 11 is rotated after the foam aluminum board is positioned, so that the pressure plate 10 presses on the surface of the foam aluminum board, thereby limiting the position of the foam aluminum board and preventing it from shifting during cutting.

[0025] In this embodiment, two supports 12 are symmetrically fixed to the surface of the cutting workbench 1 by bolts. A motor 16 is mounted on the surface of one of the supports 12. The output shaft of the motor 16 passes through the surface of the support 12 and is fixedly connected to a lead screw 15. The end of the lead screw 15 away from the motor 16 is rotatably connected to the other support 12 through a bearing. A second positioning plate 14 is threadedly connected to the surface of the lead screw 15 through a threaded cylinder. Two connecting plates 13 are symmetrically slidably connected to the surface of the second positioning plate 14. Each connecting plate 13 is fixedly connected to a corresponding first positioning plate 4. In order to avoid the foam aluminum board from developing wavy patterns due to uneven pushing speed during the moving cutting process, the motor 16 is connected to an external power source and started during cutting. The second positioning plate 14 will move due to the rotation of the lead screw 15, which will drive the first positioning plate 4 to move through the connecting plates 13. The uniform rotation of the lead screw 15 ensures that the foam aluminum board is pushed at a consistent speed.

[0026] In this embodiment, a chip guide shell 17 is fixedly connected to the inside of the cutting workbench 1 by bolts. A hose 18 is fixedly connected to the surface of the chip guide shell 17. The end of the hose 18 away from the chip guide shell 17 passes through the surface of the cutting workbench 1 and is fixedly connected to a chip collection box 19. A vacuum pump 20 is installed on the surface of the chip collection box 19. The chip guide shell 17 is located on one side of the saw blade, and the bottom surface of the chip guide shell 17 is inclined, with the side away from the saw blade being lower. When cutting the foam aluminum board, the vacuum pump 20 is connected to an external power source and then started. The chip guide shell 17 will suck the chips generated during cutting into the inside of the chip collection box 19 through the hose 18, thus avoiding chip accumulation and flying.

[0027] It should be noted that motor 16 is a servo motor with an encoder, and the number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0028] It should be noted that: In this application, an annular groove is provided axially on the inner wall of the threaded cylinder, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0029] The use of this utility model involves the following steps:

[0030] S1: When it is necessary to cut the aluminum foam board to a fixed length, place the aluminum foam board above the cutting workbench 1, and then apply force to the second guide rail 3 that is biased towards the saw blade, so that the second guide rail 3 slides on the surface of the first guide rail 2 through the slider. When the second guide rail 3 moves, the pointer 9 will move synchronously until the pointer 9 moves to the indicated position. By observing the number on the dimension table 8, determine the size to be cut off. Then, by rotating the first threaded rod 6, the rubber block 7 is inserted into the limiting groove. The friction between the rubber block 7 and the cutting workbench 1 is used to position the second guide rail 3. Then, move the second guide rail 3 on the other side so that the second guide rail 3 on the other side supports the aluminum foam board. Then, position the second guide rail 3 on the other side to achieve the positioning of the aluminum foam board. Then, push the first positioning plate 4 towards the saw blade to achieve the fixed-length cutting of the aluminum foam board.

[0031] S2: To prevent the aluminum foam board from tilting and moving due to the resistance of the saw blade when cutting, after positioning the aluminum foam board, rotate the second threaded rod 11 so that the pressure plate 10 presses on the surface of the aluminum foam board, thereby limiting the position of the aluminum foam board and preventing it from shifting during cutting.

[0032] S3: In order to avoid the foam aluminum board from having wavy patterns due to uneven pushing speed during the moving cutting process, the motor 16 is connected to an external power source and started during the cutting process. The second positioning plate 14 will move the first positioning plate 4 through the connecting plate 13 due to the rotation of the lead screw 15. The uniform rotation of the lead screw 15 ensures that the foam aluminum board is pushed at a consistent speed.

[0033] S4: When cutting the aluminum foam board, connect the vacuum pump 20 to an external power source and start it. The chip guide shell 17 will suck the chips generated during cutting into the chip collection box 19 through the hose 18, thus avoiding chip accumulation and flying.

[0034] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
