Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum veneer cutting, and particularly relates to an aluminum veneer cutting device. Background Art

[0002] An aluminum veneer refers to a building decoration material formed by processing through chromium plating and other treatments and then adopting a fluorocarbon spraying technology. The aluminum veneer is light in weight. For example, an aluminum plate with a thickness of 3.0 mm weighs 8 kg per square meter, but it has good rigidity and relatively high strength, and the tensile strength can reach 100 - 280 N / mm². Compared with traditional materials such as gypsum boards, stones, and glasses, while reducing the overall weight of the building, it can effectively ensure the safety of the building structure.

[0003] During the production of aluminum veneers, the initial size of the aluminum plates is generally large, and they need to be cut according to the finished product specifications of the aluminum veneers. Due to cost limitations, small manufacturers mostly use rotary disc knives to cut aluminum veneers. Based on actual usage requirements, some aluminum veneers are designed with a flat surface on one side and a continuous corrugated surface on the other side. This design not only enhances the three - dimensional sense and layering of the building but also performs well in acoustic properties and is commonly used in places with high requirements for sound insulation and absorption, such as concert halls and meeting rooms.

[0004] However, this structure causes the thickness of the aluminum veneer to change continuously during cutting. However, in the existing cutting equipment, the cutting speed and feed rate are fixed. When cutting to the thicker part of the aluminum veneer, the excessive feed rate will cause the cutting force borne by the saw blade to increase sharply, easily exceeding the bearing range of the saw blade and the equipment, resulting in excessive wear, chipping, or even breakage of the saw blade, greatly shortening the service life of the equipment, and seriously affecting the cutting quality at the same time.

[0014] Compared with the existing technology, the beneficial effects of the present invention are as follows: 1. Through the automatic cutting mechanism, the multi-functional laser detection mechanism, and the saw blade style auxiliary selection mechanism provided, it is possible to pre-detect the aluminum single-board to be cut, accurately determine the position with the largest thickness of the aluminum single-board. According to the relationship between the thickness of the aluminum single-board and the number of teeth of the saw blade, that is, the greater the thickness of the aluminum single-board, the greater the material resistance to be overcome during cutting, and the saw blade is required to provide a greater cutting force. For a saw blade with fewer teeth, the cutting edge of each tooth is wider and thicker, and it can withstand a greater cutting force. When cutting thick aluminum single-boards, problems such as tooth breakage and tooth fracture are not likely to occur. Based on this, it is possible to assist the staff to quickly select the most suitable saw blade, with convenient and fast operation, and greatly improve the work efficiency.

[0015] 2. By setting up an automatic cutting mechanism and a multi-functional laser detection mechanism, it is possible to detect the thickness change of the aluminum single plate in real time during the cutting process and synchronously adjust the feeding speed of the cutting. When cutting at a position with a larger thickness of the aluminum single plate, the feeding speed is automatically controlled slower. This is because cutting a thicker aluminum single plate requires a greater cutting force. If a faster feeding speed is maintained at the same cutting rotation speed, the cutting force borne by the saw blade will increase sharply, easily exceeding the load limit of the saw blade and the cutting equipment. In this way, not only will the saw blade be excessively worn, chipped or even broken, but it will also damage the cutting equipment and greatly shorten the service life of the equipment. Through this real-time monitoring and synchronous adjustment method, the stability of the cutting process can be effectively guaranteed, the service life of the saw blade and the equipment can be extended, and the cutting quality can be improved.

[0016] 3. By setting up a cutting resistance feedback mechanism, a multi-functional laser detection mechanism, a detection angle deflection mechanism, and a deflection power supply mechanism, it is possible to monitor the cutting resistance during the cutting process and quickly detect and judge whether the uneven cutting resistance is caused by the saw blade being too dull when the cutting resistance reaches the threshold value, which in turn causes a large amplitude vibration of the saw blade. And when it is confirmed that the saw blade has a large amplitude vibration, a warning signal is timely feedback to remind the staff to make corresponding handling, avoiding the problem that the overly dull saw blade continues to cut and cannot smoothly cut the aluminum single plate, resulting in burrs and affecting the cutting quality.

[0026] The PLC controller 11 is fixedly installed on the outer wall of the protective housing 9 and is electrically connected to the automatic cutting mechanism 2, the multi-functional laser detection mechanism 3, the detection angle deflection mechanism 4, the deflection power supply mechanism 5, the cutting resistance feedback mechanism 6, and the saw blade style auxiliary selection mechanism 7 respectively.

[0027] The operating principle of the present invention is described as follows: The aluminum single board to be cut is fixed to the upper end of the base 1 through a fixture, and the position of the aluminum single board to be cut is aligned with the cutting groove 8. The PLC controller 11 controls the driving motor 22 to act. The driving motor 22 drives the driving screw 21 to rotate. Through the threaded socket connection between the driving screw 21 and the driving seat 23, the driving seat 23 drives the laser rangefinder 36 to move on the upper end of the aluminum single board. The laser rangefinder 36 monitors the distance from the aluminum single board in real time and feeds the distance signal back to the PLC controller 11. The PLC controller 11 controls the power supply device to supply power to the feedback electromagnetic plate 76 based on the distance signal fed back by the laser rangefinder 36. The feedback electromagnetic plate 76 is energized to generate the same magnetic field as the feedback permanent magnet plate 75, and then provides a magnetic thrust to the feedback plate 73, so that the feedback plate 73 moves through the cooperation of the resistance sleeve 74 and the friction rod 72. Specifically, when the distance detected by the laser rangefinder 36 from the aluminum single board is shorter, it indicates that the thickness of the aluminum single board at the current position is greater. The PLC controller 11 controls the power supply device to supply a larger current to the feedback electromagnetic plate 76. When the laser rangefinder 36 completes the thickness detection of the aluminum single board, the position with the thickest aluminum single board will cause the PLC controller 11 to control the power supply device to supply the maximum current to the feedback electromagnetic plate 76, so that the feedback plate 73 moves to the farthest distance. The feedback plate 73 drives the pointer 78 to move synchronously, and then changes the position of the pointer 78 relative to the saw blade selection identification plate 77. The position where the pointer 78 finally locates corresponding to the position of the saw blade selection identification plate 77 can help the staff quickly judge the number of saw blade teeth required. The greater the thickness of the thickest position of the aluminum single board, the greater the backward movement distance of the pointer 78, and then it indicates a more backward position on the saw blade selection identification plate 77, assisting the staff to select a saw blade with fewer teeth for subsequent cutting use. After the staff selects a suitable saw blade based on the assistance, the saw blade is installed on the disk cutter 25 to prepare for the subsequent cutting work; After the PLC controller 11 drives the laser rangefinder 36 to detect the thickness change of the aluminum single plate, the PLC controller 11 controls the drive motor 22 to reverse, so that the laser rangefinder 36 and the disc cutter 25 are reset to the initial position. Then the PLC controller 11 controls the electric push rod 24 to push the disc cutter 25 downward, so that the disc cutter 25 moves to the cutting position. Then the PLC controller 11 controls the laser rangefinder 36, the disc cutter 25 and the drive motor 22 to work. The drive motor 22 drives the disc cutter 25 and the laser rangefinder 36 to move along the cutting direction of the aluminum single plate. The disc cutter 25 performs rapid cutting work on the aluminum single plate. During the cutting process, the laser rangefinder 36 continuously monitors the distance from the aluminum single plate. The shorter the monitored distance is, the greater the thickness of the current cutting position of the aluminum single plate is. The PLC controller 11 controls the drive motor 22 to work with a smaller power, reducing the cutting feed speed of the disc cutter 25. Cutting thicker aluminum single plates requires greater cutting force. If a faster feed speed is maintained at the same cutting speed, the cutting force borne by the saw blade will increase sharply, which is extremely likely to exceed the load limit of the saw blade and the cutting equipment. In this way, not only will the saw blade be excessively worn, chipped or even broken, but also the cutting equipment will be damaged, greatly shortening the service life of the equipment. Through this method of real-time monitoring and synchronous regulation, the stability of the cutting process can be effectively guaranteed, the service life of the saw blade and the equipment can be extended, and the cutting quality can be improved; When the saw blade becomes dull, due to the uneven cutting resistance of the dull saw blade, a large vibration amplitude will occur in the saw blade. At this time, the cutting resistance will also increase. The driving motor 22 is connected to the driving screw 21 through the cutting resistance feedback mechanism 6. When the cutting resistance increases, the driving motor 22 needs to provide a greater torque to the driving screw 21 to ensure the stable rotation of the driving screw 21. At this time, a greater torque connection force is required between the rotating circular shell 61 and the connecting circular plate 62. Furthermore, a strong torque connection spring 63 needs to deform to provide a greater torque connection force. As a result, the rotating circular shell 61 will deflect relative to the connecting circular plate 62. When the cutting resistance reaches the threshold value, the deflection displacement between the rotating circular shell 61 and the connecting circular plate 62 reaches the threshold value. At this time, the trigger round head 65 on the inner wall of the rotating circular shell 61 will press on the trigger switch 64 on the side wall of the connecting circular plate 62, and then feedback a warning signal to the PLC controller 11. The PLC controller 11 controls the deflection motor 32 to drive the deflection plate 33 to rotate 90 degrees, so that the laser rangefinder 36 moves to one side of the saw blade on the disk cutter 25. During the rotation of the deflection plate 33, the round head structure at the rear end of the deflection plate 33 will press on the force receiving plate 54, so that the force receiving plate 54 overcomes the elastic force of the return spring 55 through the force receiving rod 53 to push the pressurizing piston plate 52 to move. The pressurizing piston plate 52 conveys the air in the air supply shell 51 to the sealing shell 41 through the air supply pipe 56. The increased air pressure in the sealing shell 41 causes the synchronous piston plate 42 to drive the transmission rack 43 to move against the elastic force of the top push spring 45, so that the transmission rack 43 drives the transmission gear 44 to rotate self, and then drives the transmission shaft 35 to drive the laser rangefinder 36 to rotate 90 degrees, so that the detection head of the laser rangefinder 36 is aligned with the saw blade of the disk cutter 25 to detect whether the saw blade vibrates. The laser beam emitted by the laser rangefinder 36 is vertically irradiated on the surface of the saw blade, and the laser rangefinder 36 measures the distance change between the surface of the saw blade and itself in real time. If the saw blade vibrates, the distance data measured by the laser rangefinder 36 will show obvious fluctuations. By analyzing these data, the vibration condition of the saw blade can be judged. When it is detected that the saw blade vibrates with a large amplitude, the PLC controller 11 sends a signal to the receiving terminal of the staff to remind the staff to check the cutting equipment and check whether the saw blade is dull and needs to be replaced, so as to avoid the problem that the dull saw blade continues to cut, which will greatly affect the cutting efficiency and cause burrs.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
