Description

Technical Field

[0001] This invention relates to the field of plasma cutting technology, specifically to a plasma cutting device for aluminum alloy plates with intelligent path planning. Background Technology

[0002] Plasma cutting technology, as a highly efficient thermal cutting method, has been widely used in the metal processing field, especially in the processing of aluminum alloy sheets. Due to the inherent physical properties of aluminum alloys—high thermal conductivity, high coefficient of thermal expansion, and low melting point—traditional CNC plasma cutting equipment typically employs a continuous cutting path when cutting aluminum alloy sheets. This involves cutting sequentially according to the natural order of the part's outline or a simple programmed sequence. This leads to a rapid accumulation of heat in localized areas along the cutting path, creating concentrated heat input. Because aluminum alloys conduct heat quickly, the heat cannot dissipate quickly enough, resulting in significant internal stress between the heated areas and the surrounding cool areas of the sheet. When this stress exceeds the material's yield strength or is released during the cutting separation, it causes plastic deformations such as warping, bulging, and twisting of the sheet.

[0003] Thermal deformation of sheet metal can lead to a series of serious consequences: First, it can cause changes in the preset height between the cutting head and the sheet metal, resulting in unstable cutting quality, uneven cuts, or even cutting interruption; second, deformed parts may have out-of-tolerance dimensions, resulting in low yield and waste of raw materials and time; third, local overheating can also expand the heat-affected zone, making the cut wider and more angled, and producing a large amount of hard bottom slag, significantly increasing the burden of subsequent cleaning work.

[0004] In existing technologies, although a preset "skip-cut" program is used to disperse heat input, this skip-cut is often fixed and predictive, and cannot be dynamically adjusted according to the real-time temperature field and deformation state of the board during the cutting process, thus lacking adaptive capability.

[0005] Therefore, it is necessary to provide a plasma cutting device for aluminum alloy plates with intelligent path planning to solve the problems mentioned in the background art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plasma cutting device for aluminum alloy plates with intelligent path planning, comprising:

[0008] The path planning system, located on the plasma cutting head, includes temperature and deformation probes for detecting the cutting temperature on both sides of the aluminum alloy plate path, and a rotating mechanism for adjusting the movement of the temperature and deformation probes.

[0009] The cooling system, located below the heat dissipation carrier plate, is used to dissipate heat on both sides of the aluminum alloy plate path.

[0010] Preferably, two sets of temperature and deformation probes are provided and symmetrically arranged around the center of the plasma cutting head axis, comprising:

[0011] A sleeve with a push rod sliding at its lower opening, and the push rod is connected to the sleeve via a spring. The lower end of the push rod is equipped with a heat-conducting ball and a temperature sensor for monitoring the temperature of the heat-conducting ball.

[0012] The first cleaning mechanism, located on the sleeve, is used to clean the path of the heat-conducting ball bearings.

[0013] Preferably, the rotation mechanism adjusts the center line connecting the two temperature and deformation probes to be perpendicular to the cutting path of the aluminum alloy plate in real time.

[0014] Preferably, the rotating mechanism includes:

[0015] The receiving ring box is embedded in the lower end of the plasma cutting head, and a motor and a gear installed at the output end of the motor are located inside it;

[0016] The swivel ring rotates at the lower end of the housing ring box. Its lower end is used to install a sleeve, and its upper end is fixed with a gear ring that meshes with the gear.

[0017] Preferably, the cleaning mechanism includes a rotating sleeve that rotates on the outer wall of the sleeve, a ring cover that slides at the lower end of the rotating sleeve, and the ring cover is connected to the rotating sleeve by a spring. A brush strip is provided at the lower end of the ring cover, and a grid strip is provided on the outer wall of the ring cover.

[0018] Preferably, the outer wall of the lower end of the plasma cutting head is rotatably fitted with a ring fan, and one of the rotating sleeves is fixed with a rolling ring one that rolls in contact with the outer wall of the ring fan, while the other rotating sleeve is connected to a cleaning mechanism two.

[0019] Preferably, the second cleaning mechanism includes:

[0020] The ring frame is rotatably sleeved on the outer wall of the plasma cutting head. A ring plate slides at its lower end and is connected to the ring frame by a spring. A brush strip is provided at the lower end of the ring plate.

[0021] Roller ring two is fixed to the outer wall of another rotating sleeve, and its outer wall makes rolling contact with the inner wall of the ring frame.

[0022] Preferably, the cooling system includes:

[0023] A horizontal guide rail 1 is parallel to the X guide rail and located below the X guide rail, and a horizontal guide rail 2 parallel to the Y guide rail is located on it.

[0024] A rotating seat is mounted on the second horizontal guide rail, and a heat dissipation nozzle is located at the center of its upper end.

[0025] Temperature sensor 2 is configured to correspond with the temperature and deformation probe.

[0026] Preferably, the heat dissipation nozzle is provided with a filter plate at its upper opening.

[0027] Compared with the prior art, the present invention provides an intelligent path planning plasma cutting device for aluminum alloy plates, which has the following beneficial effects:

[0028] In this invention, the path planning system monitors the temperature and deformation trend on both sides of the cutting path in real time. It can actively trigger a jump-cut command before the heat accumulation reaches the dangerous threshold, transforming continuous concentrated heat input into decentralized and controllable heat input. Moreover, the real-time feedback intelligent decision-making fundamentally overcomes the blindness of traditional continuous cutting and fixed-program jump cutting, effectively suppresses the thermal deformation of aluminum alloy sheets, ensures the stability of the cutting process and the dimensional accuracy of the parts, and realizes active and intelligent thermal deformation control.

[0029] This invention prevents localized overheating, maintaining a more stable cutting environment, resulting in a uniform cut width, reduced slope, and decreased bottom slag formation. This leads to a smoother, flatter cut surface, reducing subsequent secondary processing and ensuring reliable overall product quality. Furthermore, the integrated cleaning mechanism on the probe utilizes the airflow from the cutting process itself to automatically clean the detection path, ensuring the accuracy and reliability of sensor monitoring. Simultaneously, the upward suction airflow generated by the fan promptly removes sparks and debris, improving the working environment and enhancing the equipment's safety and environmental friendliness.

[0030] This invention integrates real-time temperature and deformation sensors, intelligent analysis, and precise execution of skip-cutting and cooling into a single structure. This not only disperses heat spatially through skip-cutting but also rapidly restores high-risk areas in time through the cooling system. This achieves dynamic optimization management of the entire cutting process, effectively controlling thermal deformation and avoiding downtime for correction, parts scrap, and production line interruptions caused by sheet warping. Furthermore, the intelligent skip-cutting strategy allows cutting of other areas while waiting for one area to cool, minimizing equipment downtime and improving overall production efficiency. In addition, the stable quality and reduced scrap rate directly improve the effective utilization rate of materials. Attached Figure Description

[0038] Reference Figures 1-6 This invention provides a technical solution: an intelligent path planning plasma cutting device for aluminum alloy plates, comprising:

[0039] Processing table 1, with a heat dissipation carrier plate 11 at its upper end, an X guide rail 2 on the outer periphery of the heat dissipation carrier plate 11, a Y guide rail 3 on the X guide rail 2, a Z guide rail 4 on the Y guide rail 3, and a plasma cutting head 5 mounted on the Z guide rail 4.

[0040] The path planning system 6 is mounted on the plasma cutting head 5, and includes a temperature and deformation probe 62 for detecting the cutting temperature on both sides of the aluminum alloy plate path and a rotation mechanism 61 for adjusting the movement of the temperature and deformation probe 62.

[0041] Cooling system 7 is located below heat dissipation carrier plate 11 and is used for heat dissipation treatment on both sides of the aluminum alloy plate path.

[0042] In this embodiment, the movement of the plasma cutting head 5 is controlled by the X guide rail 2, Y guide rail 3 and Z guide rail 4 to perform intelligent path planning cutting on the aluminum alloy plate. The heat dissipation carrier plate 11 is used to hold the aluminum alloy plate. The heat dissipation carrier plate 11 has a U-shaped structure and the upper plane of the heat dissipation carrier plate 11 is provided with dense square holes so that the heat generated during the cutting of the aluminum alloy plate can be dissipated in time.

[0043] Additionally, it needs to be explained that during the continuous cutting of aluminum alloy plates by the plasma cutting head 5, heat accumulates rapidly in this area. Aluminum alloy has high thermal conductivity and a large coefficient of thermal expansion, causing the heated part to expand rapidly. However, the surrounding cooled parts constrain this expansion, leading to a sharp increase in internal stress. When the stress is released, the plate will warp, bulge, and twist. Moreover, more metal melts in the overheated area, and the plasma arc becomes more diffuse, resulting in a wider cut and a greater bevel. The molten metal cannot be completely blown away by the high-speed airflow before cooling, solidifying at the bottom of the cut and forming hard slag, making it impossible to form a smooth and flat cut surface. Therefore, through the path planning system 6 and cooling... The system 7 is configured to intelligently plan the cutting path for the aluminum alloy plate. Specifically, the temperature and deformation probe 62 is adjusted by the rotating mechanism 61 to move along the cutting path of the aluminum alloy plate. The temperature and deformation probe 62 detects the temperature and hardness on both sides of the cutting path. If the monitored temperature is higher than the preset cutting temperature range of the aluminum alloy plate, or if the monitored deformation caused by the temperature is about to exceed the cutting hardness range required by the temperature rise of the aluminum alloy plate, the plasma cutting head is adjusted on the X guide rail 2, Y guide rail 3 and Z guide rail 4 to perform a jump cut. The initial point area of ​​the jump cut is rapidly cooled by the cooling system 7 so that it can wait for the next cut to start from this point area after cooling.

[0044] In this embodiment, two sets of temperature and deformation probes 62 are provided and symmetrically arranged around the axis of the plasma cutting head 5, including:

[0045] Sleeve 621, with push rod 622 sliding at its lower opening, and push rod 622 is connected to sleeve 621 via spring 625. The lower end of push rod 622 is provided with heat-conducting ball 623 and temperature sensor 624 for monitoring the temperature of heat-conducting ball 623.

[0046] The cleaning mechanism 63, located on the sleeve 621, is used to clean the travel path of the heat-conducting ball 623.

[0047] In this embodiment, when the plasma cutting head 5 moves along the aluminum alloy plate, the heat-conducting ball 623 contacts the aluminum alloy plate and absorbs heat. The temperature sensor 624 monitors the temperature of this area and analyzes the temperature on both sides of the cutting path of the aluminum alloy plate in this area to determine whether the dynamic temperature is within a safe range. The deformation fluctuation of the spring 625 determines whether the dynamic hardness of this area is within a safe range, so as to intelligently control the optimal timing for the plasma cutting head 5 to perform jump cuts.

[0048] In addition, the cleaning mechanism 63 is used to clean the external area of ​​the heat-conducting ball 623 in real time, ensuring that it can move stably along the cutting path of the aluminum alloy plate and avoiding residue from affecting the movement and heat absorption of the heat-conducting ball 623.

[0049] In this embodiment, the rotating mechanism 61 adjusts the center line connecting the two temperature and deformation probes 62 to be perpendicular to the cutting path of the aluminum alloy plate in real time. That is, when the X guide rail 2 and Y guide rail 3 adjust the plasma cutting head 5 to move along the cutting path of the aluminum alloy plate, the preset rotating mechanism 61 adjusts the center line connecting the two temperature and deformation probes 62 to be perpendicular to the cutting path on the aluminum alloy plate in real time, thereby accurately monitoring and capturing the heat accumulation and changes on the cutting path.

[0050] In this embodiment, the rotating mechanism 61 includes:

[0051] The housing ring box 611 is embedded in the lower end of the plasma cutting head 5, and a motor 612 and a gear 613 installed at the output end of the motor 612 are provided inside it.

[0052] The rotating ring 614 rotates at the lower end of the housing ring box 611. Its lower end is used to install the sleeve 621, and its upper end is fixed with a toothed ring 615 that meshes with the gear 613.

[0053] In this embodiment, the cleaning mechanism 63 includes a rotating sleeve 631 that rotates on the outer wall of the sleeve 621. A ring cover 632 slides at the lower end of the rotating sleeve 631 and is connected to the rotating sleeve 631 by a spring 633. A brush strip 635 is provided at the lower end of the ring cover 632, and a grid strip 634 is provided on the outer wall of the ring cover 632. In other words, the airflow released by the plasma cutting head 5 can push the grid strip 634 to rotate, which can drive the ring cover 632 to rotate, thereby driving the brush strip 635 to rotate and sweep.

[0054] In this embodiment, the outer wall of the lower end of the plasma cutting head 5 is rotatably fitted with a ring fan 637, and one of the rotating sleeves 631 has a rolling ring 636 fixed on its outer wall that rolls in contact with the outer wall of the ring fan 637. The other rotating sleeve 631 is connected to a cleaning mechanism 64. That is to say, the ring cover 632 can also drive the rotating sleeve 631 to rotate, the rotating sleeve 631 drives the rolling ring 636 to rotate, and the rolling ring 636 can drive the ring fan 637 to rotate. The rotation of the ring cover 632 is unidirectional, and when the ring fan 637 is driven to rotate, the ring fan 637 draws airflow below and discharges it upward, which is beneficial for heat dissipation and discharge of sparks and flying debris generated during cutting.

[0055] In this embodiment, the second cleaning mechanism 64 includes:

[0056] The ring frame 642 is rotatably sleeved on the outer wall of the plasma cutting head 5. A ring plate 643 slides at its lower end, and the ring plate 643 is connected to the ring frame 642 by a spring 644. A brush strip 645 is provided at the lower end of the ring plate 643.

[0057] Roller ring 641 is fixed to the outer wall of another rotating sleeve 631, and its outer wall is in rolling contact with the inner wall of the ring frame 642.

[0058] In other words, another rotating sleeve 631 can drive the second rolling ring 641 installed on it to rotate, the second rolling ring 641 drives the ring frame 642 to rotate, the ring frame 642 drives the ring plate 643 to rotate, which can drive the second brush strip 645 to rotate and sweep, thereby dynamically sweeping and cleaning the cutting path area on the aluminum alloy plate.

[0059] In this embodiment, the cooling system 7 includes:

[0060] A horizontal guide rail 71 is parallel to the X guide rail 2 and located below the X guide rail 2. A horizontal guide rail 72 parallel to the Y guide rail 3 is located on it.

[0061] Rotary seat 73 is mounted on horizontal guide rail 72, and a heat dissipation nozzle 74 is provided at the center of its upper end.

[0062] Temperature sensor 75 is configured to correspond with temperature and deformation probe 62;

[0063] Specifically, the rotating seat 73 moves synchronously with the plasma cutting head 5 by adjusting the horizontal guide rail 1 71 and the horizontal guide rail 2 72. The rotating seat 73 controls the synchronous correspondence between the two temperature sensors 2 75 and the two heat-conducting balls 623. When cooling is required, the movement of the rotating seat 73 is stopped by adjusting the horizontal guide rail 1 71 and the horizontal guide rail 2 72. The heat dissipation is continuously carried out by the heat dissipation nozzle 74. The temperature change in this area is monitored and judged by the temperature sensor 2 75 until it is at a lower value within a safe range.

[0064] In this embodiment, a filter 76 is provided at the upper opening of the heat dissipation nozzle 74.

[0065] In its specific implementation, it includes the following steps:

[0066] First stage: Place the aluminum alloy plate to be cut on the U-shaped heat dissipation carrier plate 11 with dense square holes. This structure is conducive to heat dissipation. Adjust the horizontal guide rail 71 and horizontal guide rail 72 of the cooling system 7 to drive the rotating seat 73 and its heat dissipation nozzle 74 and temperature sensor 75 to keep it moving synchronously with the plasma cutting head 5, in preparation for real-time monitoring and cooling.

[0067] Second stage: Driven by the X guide rail 2, Y guide rail 3 and Z guide rail 4, the plasma cutting head 5 begins to cut the aluminum alloy plate according to the preset initial cutting path. While the plasma cutting head 5 moves, the motor 612 of the rotating mechanism 61 drives the rotating ring 614 and the two sets of temperature and deformation probes 62 symmetrically installed below it through the meshing of the gear 613 and the gear ring 615, always ensuring that the line connecting the two heat-conducting balls 623 is perpendicular to the cutting path.

[0068] Temperature monitoring: The heat-conducting ball 623 keeps in contact with the plate under the preload of spring 625 and rolls to absorb heat from both sides of the cutting path. Its temperature change is collected in real time by the built-in temperature sensor 624.

[0069] Indirect monitoring of deformation (hardness): Heat-induced softening or warping of the sheet metal leads to localized changes in its hardness. This causes varying degrees of displacement in the heat-conducting ball 623 and the push rod 622, resulting in dynamic fluctuations in the compression of the spring 625. By monitoring the deformation state of the spring, the deformation trend and hardness changes of the sheet metal can be indirectly determined.

[0070] Self-cleaning and heat dissipation assistance: The high-speed airflow ejected from the plasma cutting head 5 impacts the grid 634 of the cleaning mechanism 63, driving the ring cover 632 and brush strip 635 to rotate, cleaning the path in front of the heat-conducting ball 623 to ensure its contact and accurate temperature measurement. At the same time, the rotation of the rotating sleeve 631 drives the ring fan 637 to rotate through the rolling ring 636, generating an upward suction airflow to promptly discharge the sparks, chips and some hot air generated during cutting, improving the cutting environment.

[0071] The third stage: continuously receiving deformation feedback data from temperature sensor 624 and spring 625, when the analysis determines that the temperature of a certain area is about to exceed the preset safety threshold, and or the hardness change caused by thermal deformation is about to exceed the allowable range, it predicts that there is a serious risk of thermal deformation in that area, and immediately issues a command to the guide rail system to pause the continuous cutting of the current path, and controls the plasma cutting head 5 to jump to another safe, low-temperature area on the board to start a new cutting task. During the jump cutting, it continues to move along the preset trajectory. At this time, it continues to monitor temperature sensor 624 and spring 625. When it is determined that the temperature of a certain area is at the preset safety threshold and the hardness change is within the allowable range, cutting is performed again at this moment, thereby realizing intelligent jump cutting.

[0072] Fourth stage: After the plasma cutting head 5 performs a jump cut and leaves, its corresponding initial jump cut point (i.e., the high-temperature risk area) is locked. The rotating seat 73 of the cooling system 7 is positioned at this point. The heat dissipation nozzle 74 provides concentrated and continuous air cooling to this area. The temperature sensor 75 installed on the rotating seat 73 monitors the cooling effect of this area in real time. When the temperature sensor 75 detects that the temperature of this area has dropped to a lower value within the safe range, this area is declared to have completed cooling recovery and re-enters the cutting state, waiting for the plasma cutting head to return to this area in the subsequent path planning to complete the remaining cut.

[0073] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
