Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb core processing technology, and in particular to an automatic aluminum honeycomb core slitting machine. Background Technology

[0002] Carbon fiber reinforced aluminum honeycomb core is a lightweight and high-strength composite sandwich structure material. Its core layer is formed by stretching, bonding and curing multiple layers of compacted aluminum foil to form a continuous hexagonal honeycomb structure, which is then combined with carbon fiber panels on the upper and lower surfaces. After the multiple aluminum sheets are initially compacted, they usually need to be slit, and finally the slit aluminum honeycomb core is stretched apart by a stretching machine.

[0003] The main reason for slitting is that the core material after molding is a large-area board, while in actual application scenarios, the large board is cut into strips of core material with specific widths and lengths to meet different assembly requirements.

[0004] In existing aluminum honeycomb core panel slitting processes, although the material is pre-compacted, its internal structure remains loose and porous to maintain tensile properties. Direct circular sawing easily leads to defects such as local collapse, tearing, and burrs on the cut edges, severely affecting the quality of the finished product. Traditional slitting equipment often uses a single saw blade in a unidirectional operation mode, which is not only inefficient but also prone to overheating after cutting multiple strips, resulting in decreased cutting performance or even equipment shutdown. More importantly, the large amount of metal dust and fiber debris generated during processing is difficult to collect effectively, which not only seriously pollutes the workshop environment and endangers the health of operators but may also penetrate the honeycomb pores, posing potential quality hazards to subsequent bonding and lamination processes. Therefore, we propose an automatic aluminum honeycomb core slitting machine to solve the above problems. Utility Model Content

Detailed Implementation

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-3 As shown, an automatic aluminum honeycomb core slitting machine is disclosed, including an equipment box 1. A hollow workbench 2 is fixedly connected inside the equipment box 1. Two V-shaped ventilation filter plates 3 are fixedly connected inside the workbench 2. The two V-shaped ventilation filter plates 3 can efficiently filter the inhaled dust and debris. The V-shaped structure increases the filter contact area, improves the filtration efficiency, and reduces the probability of filter clogging.

[0024] The outer wall of the workbench 2 has two fixedly connected exhaust pipes 4, and one end of the two exhaust pipes 4 is fixedly connected to the same dust removal fan. The dual-pipeline design can make the negative pressure distribution inside the workbench 2 more uniform, ensuring that the dust in the cutting area can be quickly removed. An aluminum honeycomb core panel 5 is placed on the top of the workbench 2, and multiple through holes 6 are evenly opened on the top of the workbench 2. The coverage area of ​​the multiple through holes 6 is larger than that of the aluminum honeycomb core panel 5.

[0025] A hydraulic cylinder 7 is fixedly connected to the top of the equipment box 1. A sliding hole is opened on the top of the equipment box 1. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the hydraulic cylinder 7. A lower pressure plate 8 is fixedly connected to the bottom of the output end of the hydraulic cylinder 7. The hydraulic cylinder 7 drives the lower pressure plate 8 to move downward through the extension and retraction of the output end, thereby driving the cutting auxiliary plate 13 to pre-compact the area to be cut of the aluminum honeycomb core panel 5.

[0026] Two circular holes are opened on the outer wall of the lower pressure plate 8. The inner walls of the two circular holes are slidably connected to L-shaped rods 9. The outer walls of the two L-shaped rods 9 are slidably fitted with the same L-shaped push plate 10. The L-shaped rods 9 provide guidance for the lower pressure plate 8 and the L-shaped push plate 10. An electric push rod is fixedly connected to the top of the worktable 2. The output end of the electric push rod is fixedly connected to the outer wall of the L-shaped push plate 10. The electric push rod is located behind the L-shaped push plate 10. The L-shaped push plate 10 can convert the thrust of the electric push rod into the smooth translation of the lower pressure plate 8, which drives the compacted plate to the cutting station.

[0027] The outer wall of the pressure plate 8 is provided with a pressure assembly, which includes multiple loop-shaped parts 11. The outer wall of the pressure plate 8 is slidably connected to the inner wall of the multiple loop-shaped parts 11. The bottom of each of the multiple loop-shaped parts 11 is fixedly connected to a column 12. The bottom of each of the multiple column 12 is fixedly connected to a cutting auxiliary plate 13. The cutting auxiliary plate 13 directly contacts and presses the aluminum honeycomb core panel 5 to be cut, preventing the honeycomb wall from collapsing, tearing, and the edges from burring during cutting.

[0028] The outer wall of the equipment box 1 is equipped with a cutting assembly, which includes two cylinders 16. A linear motor 14 is fixedly connected to the outer wall of the equipment box 1. A frame 15 is fixedly connected to the outer wall of the moving end of the linear motor 14. The top of the frame 15 is fixedly connected to the outer wall of the two cylinders 16. A circular saw cutter 17 (MC350NC) is fixedly connected to the bottom of the output end of each of the two cylinders 16. The two circular saw cutters 17 (MC350NC) work together with the reciprocating motion of the linear motor 14 to achieve bidirectional cutting. Two mounting holes are opened on the outer wall of the frame 15. The inner walls of the two mounting holes are slidably connected to the outer walls of the output ends of the two cylinders 16 respectively.

[0029] Working principle: When slitting aluminum honeycomb core panel 5, first place aluminum honeycomb core panel 5 on top of workbench 2; start the dust removal fan to draw air through two air extraction pipes 4 to create negative pressure inside workbench 2. The airflow passes through multiple through holes 6 at the top, which facilitates the subsequent cutting dust being sucked into workbench 2 and filtered through two V-shaped ventilation filter plates 3.

[0030] Then the hydraulic cylinder 7 is started, and its output end pushes the lower pressure plate 8 downward. The lower pressure plate 8 drives multiple columns 12 and cutting auxiliary plate 13 that are slidably connected to it through the return piece 11 to press down together. The cutting auxiliary plate 13 first contacts and presses the area to be cut of the aluminum honeycomb core panel 5, and the positions of multiple return pieces 11 and cutting auxiliary plate 13 can be adjusted for aluminum honeycomb core panels 5 of different lengths.

[0031] Then the electric push rod is activated, pushing the L-shaped push plate 10 to slide along the two L-shaped rods 9, thereby driving the lower pressure plate 8 and all the cutting auxiliary plates 13 to move laterally, positioning the aluminum honeycomb core panel 5 to the cutting station;

[0032] At this time, the linear motor 14 drives the frame 15 to move to the predetermined slitting position. One of the cylinders 16 is activated, driving the connected circular saw cutter 17 to descend and perform high-speed slitting of the aluminum honeycomb core panel 5, which has been pressed and fixed by the cutting auxiliary plate 13. During the return process, the linear motor 14 operates through another cylinder 16, driving the connected circular saw cutter 17 to descend, and the two circular saw cutters 17 perform back and forth cutting.

[0033] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the hydraulic cylinder 7, linear motor 14, air cylinder 16, circular saw cutter 17, and electric push rod to facilitate overall control.
