Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive waterproof PHC honeycomb panel processing technology, specifically an automotive waterproof PHC honeycomb panel cutting mechanism. Background Technology
[0002] Automotive waterproof PHC honeycomb panels are lightweight, high-strength composite materials. They consist of a paper core as a support and fiberglass felt as reinforcement on both the top and bottom surfaces. The material is coated with PU spraying technology to form a foamed preform, and finally hot-pressed foaming molding. They are widely used in various parts of automobiles, such as spare tire covers, sunroofs, and sun visors.
[0003] When processing automotive waterproof PHC honeycomb panels on the production line, the panels need to be pre-cut. To ensure that the required size of the PHC honeycomb panels meets the usage requirements, they are initially cut slightly larger before being cut to more precise dimensions. However, during this subsequent cutting, the four sides of the PHC honeycomb panels are typically trimmed to remove any scrap material. In existing technology, a cutter of a specified shape is lowered to cut the four sides of the PHC honeycomb panels. However, when the cutter descends, the pressure from the cutter causes the edges of the PHC honeycomb panels to lift, affecting the cutting accuracy. Furthermore, after cutting, workers must manually remove the scrap material from the four sides of the PHC honeycomb panels, which is a cumbersome process. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a cutting mechanism for automotive waterproof PHC honeycomb panels includes a workbench 1. A hydraulic rod 2 is fixedly installed on the top of the workbench 1. A lifting plate 3 is fixedly installed through the moving end of the hydraulic rod 2, passing through the workbench 1. An annular cutter 4 for cutting automotive waterproof PHC honeycomb panels is fixedly installed on the lower surface of the lifting plate 3. A side cutter 5 is integrally fixedly installed on one side of the annular cutter 4. The side cutter 5 is used to cut the automotive waterproof PHC honeycomb panels. An extrusion plate 6 for pressing and positioning the automotive waterproof PHC honeycomb panels is slidably installed on the lower surface of the lifting plate 3. The extrusion plate 6 is located below the annular cutter 4. A placement platform 7 is fixedly installed on the working surface of the workbench 1. A tool for pulling the cutter is slidably installed on the workbench 1 on the side corresponding to the placement platform 7. The pull rod 8 of the automotive waterproof PHC honeycomb panel descends via the hydraulic rod 2, driving the lifting plate 3 to fall. The extrusion plate 6 first contacts and extrudes the automotive waterproof PHC honeycomb panel to control its stability and prevent the four sides of the automotive waterproof PHC honeycomb panel from lifting up when the annular cutter 4 cuts them. As the lifting plate 3 descends, the annular cutter 4 on the lifting plate 3 cuts the four sides of the automotive waterproof PHC honeycomb panel, cutting off the scrap. At the same time, the side cutter 5 cuts off the scrap. Then, the moving block 15 is moved, and the pull rod 8 pulls the cut scrap to slide it out of the middle of the worktable 1. This eliminates the need for manual scrap unloading, making scrap unloading easier.
[0022] like Figures 1 to 5 As shown, a limiting rod 9 is symmetrically fixedly installed on the top of the extrusion plate 6. A limiting hole 10 is opened in the middle of the lifting plate 3 corresponding to the position of the limiting rod 9. The limiting hole 10 is slidably connected to the limiting rod 9. A return spring 11 is sleeved on the outer side of the top of the limiting rod 9. One end of the return spring 11 is fixedly connected to the top of the limiting rod 9, and the other end of the return spring 11 is fixedly connected to the top of the lifting plate 3.
[0023] The lifting plate 3 is lowered by the hydraulic rod 2. The extrusion plate 6 will first contact and extrude the automotive waterproof PHC honeycomb panel. As the lifting plate 3 descends, the limit rod 9 will slide inside the limit hole 10. At this time, the return spring 11 is in a stretched state, which is used to control the stability of the four sides of the automotive waterproof PHC honeycomb panel. The return spring 11 prevents the extrusion plate 6 from excessively extruding the automotive waterproof PHC honeycomb panel.
[0024] like Figures 1 to 5 As shown, the annular cutter 4 and the side cutter 5 surround each other to form a storage groove 12 for accommodating the extrusion plate 6.
[0025] It can be used to store the extruded plate 6 when cutting the four sides of the automotive waterproof PHC honeycomb panel.
[0026] like Figures 1 to 5 As shown, an extension table 13 is integrally fixedly installed on one side of the workbench 1. Positioning rods 14 are symmetrically fixedly installed between the ends of the workbench 1 and the extension table 13. A moving block 15 is slidably installed between the two positioning rods 14. The pulling rod 8 is installed on the top of the moving block 15. The moving block 15 has a positioning hole 16 corresponding to the position of the positioning rod 14. The positioning hole 16 is slidably connected to the positioning rod 14. A screw 17 is rotatably installed between the ends of the workbench 1 and the extension table 13 through a bearing. The screw 17 is threadedly connected to the middle of the moving block 15. A servo motor 18 is fixedly installed inside the workbench 1 at the position corresponding to the screw 17. The output end of the servo motor 18 is fixedly connected to the end of the screw 17.
[0027] The servo motor 18 drives the screw 17 to rotate. The positioning rod 14 limits the movement of the moving block 15, and the screw 17 and the moving block 15 are connected by threads to move the moving block 15. The pulling rod 8 pulls the cut scraps to slide them out of the middle of the worktable 1.
[0028] like Figures 1 to 5 As shown, the top of the moving block 15 has a receiving hole 19, the pulling rod 8 is slidably installed inside the limiting rod 9, the bottom of the pulling rod 8 is fixedly installed with a compression spring 20, the bottom end of the compression spring 20 is fixedly connected to the bottom end of the moving block 15 corresponding to the compression spring 20, a triangular block 21 is fixedly installed on the outside of the pulling rod 8, and a compression slope 22 is opened on one side of the placement platform 7 corresponding to the position of the triangular block 21, the compression slope 22 and the triangular block 21 are in compression contact.
[0029] After the scrap material is cut, the rear control uses the servo motor 18 to control the moving block 15 to move in the opposite direction. When the moving block 15 moves to the placement table 7, the squeezing of the triangular block 21 by the squeezing slope 22 will cause the pulling rod 8 to be stored inside the moving block 15. The top of the pulling rod 8 will be lower than the top of the placement table 7 to prevent the pulling rod 8 from interfering with the cutting of the four sides of the automotive waterproof PHC honeycomb panel by the annular cutter 4.
[0030] like Figures 1 to 5 As shown, the lowest end of the triangular block 21 is set lower than the highest end of the extrusion slope 22.
[0031] This is to ensure that the extrusion ramp 22 can always extrude the triangular block 21, and to ensure that the pull rod 8 can always be stored inside the moving block 15.
[0032] This utility model provides a cutting mechanism for automotive waterproof PHC honeycomb panels, the specific working principle of which is as follows:
[0033] When the device is in use, the automotive waterproof PHC honeycomb panel is placed on the placement platform 7, with all four sides of the automotive waterproof PHC honeycomb panel extending beyond the four sides of the placement platform 7. Then, the lifting plate 3 is lowered by the hydraulic rod 2. The extrusion plate 6 will first contact and extrude the automotive waterproof PHC honeycomb panel. As the lifting plate 3 descends, the limiting rod 9 will slide inside the limiting hole 10. At this time, the return spring 11 is in a stretched state to control the stability of the automotive waterproof PHC honeycomb panel. Then, as the lifting plate 3 descends, the annular cutter 4 on the lifting plate 3 will cut the four sides of the automotive waterproof PHC honeycomb panel to cut off the scrap material. At the same time, the side cutter 5 will cut off the scrap material. Then, the hydraulic rod 2 is controlled to raise the lifting plate 3. The pull of the top of the limiting rod 9 by the return spring 11 will cause the limiting rod 9 to slide in the opposite direction inside the limiting hole 10, which is used to drive the relative sliding of the extrusion plate 6 and the lifting plate 3.
[0034] Subsequently, the servo motor 18 drives the screw 17 to rotate. The positioning rod 14 limits the movement of the moving block 15, and the screw 17 and the moving block 15 are connected by threads to move the moving block 15. As the moving block 15 moves, the compression spring 20 pushes the pulling rod 8 upward. The pulling rod 8 will exceed the top of the placement table 7. Then, as the moving block 15 moves, the pulling rod 8 will pull the cut scraps to slide them out of the middle of the worktable 1 for scrap unloading. Then, the servo motor 18 controls the moving block 15 to move in the opposite direction. When the moving block 15 moves to the placement table 7, the compression of the triangular block 21 by the compression slope 22 will cause the pulling rod 8 to be stored inside the moving block 15. The top of the pulling rod 8 will be lower than the top of the placement table 7.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
