Description

Technical Field

[0001] This application relates to the field of titanium alloy cutting, and in particular to a method, apparatus, system, equipment and medium for controlling the cutting of titanium alloys. Background Technology

[0002] Titanium alloys refer to various alloys made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloys are characterized by high strength, good corrosion resistance, and high heat resistance. Titanium alloys have particularly important applications in aerospace, marine development, power, and chemical industries. As the applications of titanium alloys continue to expand, there is a need to cut titanium and finished products such as titanium alloy plates and rods to adapt them to the needs of different industries.

[0003] To simplify the cutting process, one common method is to submerge the titanium and titanium alloy workpieces to be cut in water to a certain depth and use underwater precision plasma arc cutting or high-pressure water jet cutting. During cutting, the process parameters are adjusted according to the thickness of the workpiece and the power of the plasma cutting machine.

[0004] However, the commonly used methods have the following technical problems: During the cutting process, titanium alloy residue or cutting materials will settle in the water, causing changes in the weight of the titanium alloy workpiece. These weight changes will alter the forces acting on the workpiece in the water, making it prone to floating or swaying during cutting, leading to cutting deviations and reduced cutting accuracy. Summary of the Invention

[0005] In view of the aforementioned problems, this application is made to provide a method, apparatus, system, device, and medium for controlling the cutting of titanium alloys that overcomes or at least partially solves the aforementioned problems, comprising:

[0006] A method for controlling the cutting of titanium alloys, the method comprising:

[0007] After the titanium alloy is submerged in the cutting water tank, the initial weight of the titanium alloy is detected and the initial stress value is calculated using the initial weight value.

[0008] After the cutting equipment is started to cut the titanium alloy in the cutting tank, the weight value of the residue in the cutting tank is determined, and the real-time weight value of the titanium alloy is calculated using the weight value of the residue.

[0009] The weight difference is calculated based on the initial force value and the real-time weight value, and the cutting parameters are determined based on the magnitude of the weight difference, so as to control the cutting equipment to cut the titanium alloy using the cutting parameters.

[0010] In one possible implementation, determining the weight of the residue in the cutting tank includes:

[0011] The first inspection image was taken from the bottom of the cut water tank;

[0012] The first detection image is subjected to residue identification to obtain a residue area image, which is an image of fine titanium alloy residue deposited in the corresponding area of ​​the cutting water tank.

[0013] After calculating the area of ​​the image of the residue region to obtain the area value, the weight value corresponding to the area value is calculated according to the preset first image conversion ratio to obtain the weight value of the residue.

[0014] In one possible implementation, determining the cutting parameters based on the magnitude of the weight difference includes:

[0015] If the cutting equipment is a high-pressure water cutter, then calculate the change in water volume in the cutting water tank. The change in water volume is the difference between the water volume of the cutting water tank before the titanium alloy was placed and the water volume of the cutting water tank at the current time point.

[0016] If the weight difference is greater than the preset first weight value and the water volume change value is greater than the preset water volume value, then the current water capacity of the cutting water tank is adjusted to the water capacity before the titanium alloy is placed, the weight ratio of the weight difference to the initial weight value is calculated, and the output water pressure value of the cutting equipment is reduced according to the weight ratio to obtain the cutting parameters.

[0017] If the weight difference is less than a preset first weight value and the water volume change is less than a preset water volume value, then the current output water pressure value of the cutting device is obtained to get the cutting parameters;

[0018] If the weight difference is greater than a preset first weight value and the water volume change is less than a preset water volume value, then the weight ratio of the weight difference to the initial weight value is calculated, and the output water pressure of the cutting device is reduced by multiplying the weight ratio by a preset first weight coefficient to obtain the cutting parameters.

[0019] In one possible implementation, determining the weight of the residue in the cutting tank includes:

[0020] A second detection image is taken from the side of the cut water tank. Particle identification is performed on the second detection image to obtain multiple images of residue particles. Each image of residue particles is an image of titanium alloy granular residue deposited on the cut water tank.

[0021] After calculating the area of ​​each of the residue particle images to obtain the particle area value, the sum of the multiple particle area values ​​is calculated, and the weight value corresponding to the sum value is calculated according to the preset second image conversion ratio to obtain the residue weight value.

[0022] In one possible implementation, determining the cutting parameters based on the magnitude of the weight difference, and using the cutting parameters to control the cutting equipment to cut the titanium alloy, includes:

[0023] If the cutting equipment is a plasma cutter, the number of residue particles in multiple images is counted to obtain the residue particle quantity value;

[0024] If the weight difference is less than a preset second weight value and the number of residue particles is less than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and increase the output power of the cutting equipment based on the weight ratio to obtain the cutting parameters;

[0025] If the weight difference is greater than a preset second weight value and the number of residue particles is greater than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and reduce the output power of the cutting equipment by multiplying the weight ratio by the preset second weight coefficient to obtain the cutting parameters;

[0026] If the weight difference is greater than a preset second weight value and the number of residue particles is less than a preset number value, then the current output power of the cutting equipment is obtained to get the cutting parameters.

[0027] In one possible implementation, after the step of controlling the cutting equipment to cut the titanium alloy using the cutting parameters, the method further includes:

[0028] Obtain the cutting time for titanium alloys;

[0029] If the cutting time exceeds the preset time, an alarm will be issued to the user.

[0030] A cutting control device for titanium alloys, the device comprising:

[0031] The detection module is used to detect the initial weight of the titanium alloy after it is submerged in the cutting water tank and to calculate the initial stress value using the initial weight value.

[0032] The calculation module is used to determine the weight of the residue in the cutting water tank after the cutting equipment is started to cut the titanium alloy in the cutting water tank, and to calculate the real-time weight of the titanium alloy using the weight of the residue.

[0033] The control module is used to calculate the weight difference based on the initial force value and the real-time weight value, and to determine the cutting parameters based on the magnitude of the weight difference, so as to control the cutting equipment to cut the titanium alloy using the cutting parameters.

[0034] A titanium alloy cutting control system, the system comprising: a control unit and a device body, the control unit being adapted to the titanium alloy cutting control method described above, the control unit being disposed on the device body;

[0035] The device body is equipped with a cutting water tank for holding titanium alloy and a camera for filming the cutting water tank.

[0036] An apparatus includes a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein the computer program, when executed by the processor, implements the steps of cutting control of titanium alloy as described above.

[0037] A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of cutting control of titanium alloy as described above.

[0038] This application has the following advantages:

[0039] In the embodiments of this application, after the titanium alloy is submerged in the cutting water tank, the initial weight value of the titanium alloy is detected and the initial force value is calculated using the initial weight value; after cutting is started, the weight value of the residue in the cutting water tank is determined and the real-time weight value of the titanium alloy is calculated using the residue weight value; the weight difference is calculated based on the initial force value and the real-time weight value, and the cutting parameters are determined based on the magnitude of the weight difference, so as to control the cutting equipment to cut the titanium alloy using the cutting parameters; this application can adjust the parameters of the cutting equipment in real time according to the weight change of the titanium alloy during the cutting process, so as to reduce the influence of the surrounding environment on the titanium alloy, thereby reducing the cutting deviation and improving the cutting accuracy.

[0045] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0046] The inventors, through analysis of existing technology, discovered that during the cutting process, titanium alloy residue or cutting materials can deposit in the water, causing a change in the weight of the titanium alloy workpiece. This weight change alters the forces acting on the workpiece in the water, making it prone to floating or swaying during cutting, leading to cutting deviations and reduced cutting accuracy.

[0047] Reference Figure 1 The diagram shows a flowchart of the steps of a titanium alloy cutting control method according to an embodiment of this application.

[0048] In one embodiment, the method is applicable to the control unit of a titanium alloy cutting device, which may be a high-pressure water jet cutter or a plasma cutter.

[0049] S11. After the titanium alloy is submerged in the cutting water tank, the initial weight value of the titanium alloy is detected and the initial force value is calculated using the initial weight value.

[0050] In one embodiment, the cutting water tank is a tank for holding titanium alloy. After the titanium alloy is placed in the tank, the cutting equipment can be used to cut the titanium alloy. During the cutting process, the cutting residue and titanium alloy particles can be deposited in the cutting water tank. During cutting, the entire workpiece is submerged in water, so the workpiece deformation after cutting is minimal. This is very suitable for cutting long, thin plates. The process is easy to implement, improves the quality of the kerf, has a wide cutting range, high cutting speed, high efficiency, and higher cutting accuracy than flame cutting. Moreover, underwater cutting results in less deformation, reduces slag buildup on the cut surface compared to plasma arc cutting, improves the quality of material preparation and work efficiency, and completely eliminates the pollution of the working environment by dust, arc light, and noise. This technology can be widely used in CNC underwater plasma cutting of titanium metal.

[0051] In practical applications, oil and dust can be removed from the surface of the titanium alloy first to keep it clean. Then, clamp one end of the titanium alloy workpiece to be cut, while the other end is used for cutting, and the titanium alloy is placed in the cutting water tank. Optionally, the clamp can be directly set inside the cutting water tank. Alternatively, the titanium alloy workpiece to be cut can be placed directly in the worktable of the cutting water tank, and cutting can be performed inside the worktable.

[0052] Next, water can be filled into the cutting water tank until it covers the workpiece surface by 5-10mm. The water level can be adjusted arbitrarily.

[0053] If an underwater plasma arc cutting machine is used for cutting titanium alloy workpieces, the process parameters, including arc initiation parameters and cutting process parameters, can be determined according to the thickness of the workpiece. At the same time, nitrogen, argon, or compressed air can be used as the cutting gas source for generating the plasma arc and the protective gas source for the plasma cutting machine. The cutting gas and protective gas should be turned on and kept at a constant volume flow rate.

[0054] After cutting is complete, drain the water from the cutting tank so that the titanium alloy workpiece can be exposed above the water surface.

[0055] During the cutting process, some titanium alloy residue may accumulate in the water tank, making the titanium alloy lighter. The water may then cause the titanium alloy to float, leading to movement and cutting deviations. If a high-pressure water gun is used, the water may also push the titanium alloy, causing it to shift and resulting in cutting deviations.

[0056] Therefore, the initial weight of the titanium alloy can be detected, and the initial force can be calculated using this initial weight. Specifically, the initial weight is calculated by weighing the titanium alloy before it is placed in the cutting water tank, or it can be obtained by weighing the titanium alloy before the cutting water tank is filled with water. Simultaneously, the initial force can be calculated from the initial weight; this initial force is the buoyancy force experienced by the titanium alloy within the water tank, which can be calculated using a standard buoyancy calculation formula.

[0057] S12. After starting the cutting equipment to cut the titanium alloy in the cutting tank, determine the weight value of the residue in the cutting tank, and use the weight value of the residue to calculate the real-time weight value of the titanium alloy.

[0058] After calculating the initial stress value, the cutting equipment can be started to cut the titanium alloy. At the same time, during the cutting process, the weight of the cut residue can be detected in real time in the cutting water tank to obtain the residue weight value. Then, by subtracting the residue weight value from the initial weight value, the real-time weight value of the titanium alloy can be calculated.

[0059] Whether it's a high-pressure water jet cutter or a plasma cutter, during the cutting process, residue will flow with the water and then settle in the cutting water tank. Generally, the residue will settle in the middle of the cutting water tank. A weight sensor can be installed at the bottom of the cutting water tank to detect the weight of the residue.

[0060] In an optional embodiment, the residue is very fine and may be deposited at different locations due to the water flow in the cutting tank during cutting, potentially forming multiple areas within the cutting tank. To comprehensively calculate the weight of these multiple areas, determining the weight of the residue within the cutting tank, as an example, may include the following sub-steps:

[0061] S21. Take the first inspection image from the bottom of the cut water tank.

[0062] S22. Perform residue identification on the first detection image to obtain a residue area image, wherein the residue area image is an image of fine titanium alloy residue deposited in the corresponding area of ​​the cutting water tank.

[0063] S23. After calculating the area of ​​the image of the residue region to obtain the area value, calculate the weight value corresponding to the area value according to the preset first image conversion ratio to obtain the weight value of the residue.

[0064] Specifically, a camera can be installed at the bottom of the cutting tank. This camera can capture images from the bottom of the tank, obtaining a first detection image. The first detection image can then be used to determine which area of ​​the tank bottom has the residue deposited, and the weight of the residue can be determined by combining the images from each area.

[0065] Because titanium alloys and water differ in color, a preset color recognition model can be used to identify residues in the first detection image based on chromaticity values, thus obtaining an image of the residue region. For example, water is transparent, while titanium alloys are silver or gray. Silver and gray areas within the first detection image can be identified, and the corresponding images for those areas can be obtained. These areas represent the regions where fine titanium alloy residues are deposited, thus providing an image of the residue region.

[0066] Because the residue particles are small, they generally disperse during deposition and the deposition thickness is not high. Therefore, the area of ​​the residue region can be calculated from the image area. Specifically, the area value of the region can be obtained by calculating the area of ​​the image. If there are multiple residue region images, the area value of the region corresponding to each residue region image can be calculated, and then the area values ​​of the multiple regions can be summed to obtain the total area value.

[0067] Finally, the weight value corresponding to the area value can be calculated according to the preset first image conversion ratio to obtain the weight value of the residue.

[0068] The preset first image conversion ratio can be a user-defined conversion ratio value. In a practical application, during the initial cutting process, water in the cutting tank can be drained every minute of cutting, and the area and weight of the fine residue deposited in the tank at that time can be calculated, and then the ratio can be calculated. After repeating the experiment multiple times (e.g., 10 times), an area-to-weight ratio can be calculated.

[0069] Each time the area value of a region is calculated subsequently, the product of the area value and the preset first image conversion ratio can be calculated to obtain the weight value of the residue.

[0070] In another alternative embodiment, the titanium alloy to be cut may be a highly irregular titanium alloy, and the cutting is intended to give it a regular structure. For example, an uneven side surface can be cut to create a smooth surface. During cutting, the resulting residue may consist of large particles or scraps. The larger particles of residue may also deposit in water, but they generally have low fluidity and tend to accumulate together to form a deposit pile with a certain height.

[0071] To comprehensively calculate the weight of residue from multiple sediment piles of a certain height, the determination of the residue weight value within the cutting tank, as an example, may include the following sub-steps:

[0072] S31. Take a second detection image from the side of the cutting water tank, perform particle identification on the second detection image to obtain multiple residue particle images, each of which is an image of titanium alloy granular residue deposited on the cutting water tank.

[0073] S32. After calculating the area of ​​each of the residue particle images to obtain the particle area value, calculate the sum of the multiple particle area values, and calculate the weight value corresponding to the sum according to the preset second image conversion ratio to obtain the residue weight value.

[0074] Specifically, a camera can be installed on the side of the cut water tank. This camera can capture images from the side of the cut water tank, obtaining a second detection image. The height of the residue deposited at the bottom of the tank can be determined from this second detection image, and then the weight of the residue can be determined based on the deposition height.

[0075] Since titanium alloy differs in color from water, and granular titanium alloy has a certain volume, a preset color recognition model can be used to identify particles in the second detection image based on chromaticity values. This allows for the identification of individual particle residues, with each residue particle corresponding to a separate particle image. Multiple particle images are then obtained. For example, water is transparent, while titanium alloy is black. The black areas within the second detection image can be identified to obtain a particle image corresponding to a single residue particle.

[0076] Because the residue particles are relatively large, they generally accumulate together during deposition, resulting in a certain height. Therefore, the area of ​​each residue particle image can be calculated, and the volume of the residue particle can be determined by the area, which in turn allows us to determine its weight.

[0077] Since there are multiple images of residue particles, and thus multiple corresponding particle numbers, we can first calculate the area of ​​each residue particle image to obtain the particle area value, and then calculate the sum of the multiple particle area values.

[0078] Finally, the weight value corresponding to the sum can be calculated according to the preset second image conversion ratio to obtain the weight value of the residue.

[0079] The preset second image conversion ratio can be a user-defined conversion ratio value. In one practical application, the preset second image conversion ratio can be the product of the height and density of the titanium alloy. The height of the titanium alloy can be the width of the current titanium alloy cut. Specifically, the preset second image conversion ratio can also be adjusted according to actual needs.

[0080] S13. Calculate the weight difference based on the initial force value and the real-time weight value, and determine the cutting parameters based on the magnitude of the weight difference, so as to control the cutting equipment to cut the titanium alloy using the cutting parameters.

[0081] In one embodiment, the real-time force on the titanium alloy in water, i.e., its buoyancy at its current weight, can be calculated based on the real-time weight value. Then, the weight difference is calculated by subtracting the initial force value from the real-time force value.

[0082] Next, based on the magnitude of the weight difference, it can be determined whether parameter adjustments are needed. If so, the output parameters of the current cutting equipment can be adjusted to obtain the cutting parameters. Finally, the cutting parameters can be used to control the cutting equipment to cut the titanium alloy.

[0083] For example, if the weight difference is large, the cutting equipment might cut most of the titanium alloy in a very short time, exceeding expectations, potentially resulting in workpiece deviation. Conversely, if the weight difference is small, the cutting equipment might only cut a small portion of the titanium alloy over a longer period, requiring increased power to improve cutting efficiency. Alternatively, if the weight difference is also large, the cutting equipment might have cut most of the titanium alloy, leaving a small volume of remaining alloy. In this case, reducing the output power can help stabilize the titanium alloy during cutting, preventing it from sloshing in water and improving cutting accuracy.

[0084] In one embodiment, the cutting equipment may be a water jet cutter. During the cutting process, high-pressure water is continuously injected into the cutting water tank, causing the water volume of the tank to continuously increase. However, if high-pressure water continues to be injected while the titanium alloy is shrinking in volume, the scouring effect of the high-pressure water will destabilize the titanium alloy, and the high-pressure water will also overflow.

[0085] To address the ever-changing water volume in a timely manner, as an example, determining the cutting parameters based on the weight difference may include the following sub-steps:

[0086] S41. If the cutting equipment is a high-pressure water jet cutter, calculate the change in water volume in the cutting water tank. The change in water volume is the difference between the water volume of the cutting water tank before the titanium alloy was placed and the water volume of the cutting water tank at the current time point.

[0087] S42. If the weight difference is greater than the preset first weight value and the water volume change value is greater than the preset water volume value, then adjust the current water capacity of the cutting water tank to the water capacity before placing the titanium alloy, calculate the weight ratio of the weight difference to the initial weight value, and adjust the output water pressure value of the cutting equipment according to the weight ratio to obtain the cutting parameters.

[0088] S43. If the weight difference is less than a preset first weight value and the water volume change value is less than a preset water volume value, then obtain the current output water pressure value of the cutting device and obtain the cutting parameters.

[0089] S44. If the weight difference is greater than a preset first weight value and the water volume change is less than a preset water volume value, then calculate the weight ratio of the weight difference to the initial weight value, and adjust the output water pressure of the cutting device by multiplying the weight ratio by the preset first weight coefficient to obtain the cutting parameters.

[0090] In a specific operating procedure, if the cutting equipment is a high-pressure water jet cutter, the change in water volume in the cutting water tank can be calculated first.

[0091] Specifically, you can first calculate the water capacity of the water tank before placing the titanium alloy, then determine the water capacity of the water tank at the current time point, and then calculate the difference between the two water capacities to obtain the water volume change value.

[0092] If the weight difference exceeds the preset first weight value and the water volume change exceeds the preset water volume value, it indicates a significant change in the titanium alloy, potentially cutting through a large portion of the structure, while the high-pressure water jet cutter has injected a large amount of water into the cutting tank. To minimize the impact of water, the current water capacity of the cutting tank can be adjusted to the capacity before the titanium alloy was placed. This can be achieved by draining the water through the tank's internal water pipe, then calculating the ratio of the weight difference to the initial weight value to obtain the weight ratio. Since a substantial amount of titanium alloy has already been cut, the output water pressure of the cutting equipment can be reduced according to the weight ratio to obtain the cutting parameters.

[0093] Specifically, the output water pressure of the cutting equipment can be reduced by a percentage based on the weight ratio, and the reduced output water pressure value can be used as the cutting parameter. For example, if the weight ratio is 0.2, the output water pressure of the cutting equipment can be reduced by 20%, and the reduced output water pressure value can be used as the cutting parameter.

[0094] Similarly, if the weight difference is less than the preset first weight value and the water volume change is less than the preset water volume value, it indicates that only a small portion of the titanium alloy has been cut and the injected water volume is small, possibly indicating that cutting has just begun. In this case, the current output water pressure value of the cutting equipment can be directly obtained, and the current output water pressure value can be used as the cutting parameter.

[0095] Similarly, if the weight difference is greater than a preset first weight value and the water volume change is less than a preset water volume value, it means that most of the titanium alloy can be cut using only a small amount of water. To reduce equipment energy consumption, decrease water consumption, and avoid cutting deviations caused by high water pressure scouring the remaining titanium alloy, the weight ratio of the weight difference to the initial weight value can be calculated. The output water pressure of the cutting equipment can then be reduced by multiplying this weight ratio by a preset first weight coefficient to obtain the cutting parameters. Specifically, the output water pressure of the cutting equipment can also be reduced by a percentage of the product, and the reduced output water pressure value can be used as the cutting parameters.

[0096] For example, if the product of the first weight coefficient is preset to 2 and the weight ratio is 0.2, the product is 0.4. The output water pressure of the cutting equipment can be reduced by 40%, and then the reduced output water pressure value can be used as the cutting parameter.

[0097] In another embodiment, the cutting equipment may be a plasma cutter. During the cutting process, different power levels result in varying flatness when cutting titanium alloys of different sizes. In this case, the power of the plasma cutter can be adjusted according to the size variation of the titanium alloy to improve the cutting accuracy.

[0098] As an example, determining the cutting parameters based on the weight difference may include the following sub-steps:

[0099] S51. If the cutting equipment is a plasma cutting machine, the number of the multiple images of the residue particles is counted to obtain the residue particle quantity value.

[0100] S52. If the weight difference is less than a preset second weight value and the number of residue particles is less than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and adjust the output power of the cutting equipment according to the weight ratio to obtain the cutting parameters.

[0101] S53. If the weight difference is greater than a preset second weight value and the number of residue particles is greater than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and reduce the output power of the cutting device by multiplying the weight ratio by the preset second weight coefficient to obtain the cutting parameters.

[0102] S54. If the weight difference is greater than a preset second weight value and the number of residue particles is less than a preset number value, then obtain the current output power of the cutting equipment and obtain the cutting parameters.

[0103] Specifically, if the cutting equipment is a plasma cutter, you can first count the number of multiple images of residue particles. Since each particle can correspond to one image of residue particles, counting the number of images of residue particles can give you the number of residue particles.

[0104] If the weight difference is less than the preset second weight value and the number of residue particles is less than the preset number value, it indicates that the volume change of the titanium alloy is small and there are fewer large-volume particles produced by cutting, indicating that the flatness of the cut is appropriate. In order to improve the cutting efficiency, the weight ratio of the weight difference to the initial weight value can be calculated, and the output power of the cutting equipment can be increased by a percentage of the weight ratio. The increased output power is used as the cutting parameter.

[0105] For example, if the weight ratio is 0.2, the output power of the cutting equipment can be increased by 20%, and then the increased output power can be used as the cutting parameter.

[0106] Similarly, if the weight difference is greater than the preset second weight value and the number of residue particles is greater than the preset number value, it indicates that the volume change of the titanium alloy is large, and there are more large particles produced during cutting, resulting in lower cut smoothness. Therefore, the power needs to be appropriately reduced. Alternatively, the weight ratio of the weight difference to the initial weight value can be calculated, and then the product of this weight ratio and the preset second weight coefficient can be calculated. The output power of the cutting equipment can be reduced by a percentage based on this product, and the reduced output power can be used as the cutting parameter.

[0107] For example, if the product of the second weight coefficient is preset to 3 and the weight ratio is 0.11, the product is 0.33. The output power of the cutting equipment can be reduced by 33%, and then the reduced output power can be used as the cutting parameter.

[0108] If the weight difference is greater than the preset second weight value and the number of residue particles is less than the preset number value, it indicates that the volume change of the titanium alloy is large, but the large-volume particles produced by cutting are small and the flatness of the cut is moderate. The cutting parameters can be left unchanged for the time being. The current output power of the cutting equipment can be obtained and the current output power can be used as the cutting parameters.

[0109] In an optional embodiment, various malfunctions or unexpected events may occur during the cutting process. The user may require half an hour to cut the titanium alloy, but the cutting equipment malfunctions, and the process fails to complete after one hour. To promptly notify the user, the method, as an example, may further include the following steps:

[0110] S14. Obtain the cutting time of the titanium alloy;

[0111] S15. If the cutting time exceeds the preset time, an alarm prompt will be sent to the user.

[0112] Specifically, the cutting duration is the interval from the start of cutting to the current time point, and can be timed from the start of cutting. The preset duration is the duration entered by the user before starting cutting, which is the duration the user needs to evaluate the cutting. If the cutting duration exceeds the preset duration, an alarm can be triggered to the user or technical personnel to prompt the user to check.

[0113] In this embodiment, the present application provides a method for controlling the cutting of titanium alloys. Its advantages are as follows: After the titanium alloy is submerged in the cutting water tank, the initial weight of the titanium alloy is detected, and the initial force is calculated using this initial weight. After cutting begins, the weight of the residue in the cutting water tank is determined, and the real-time weight of the titanium alloy is calculated using this residue weight. The weight difference is calculated based on the initial force and the real-time weight, and cutting parameters are determined based on the magnitude of the weight difference. These cutting parameters are then used to control the cutting equipment to cut the titanium alloy. During the cutting process, the parameters of the cutting equipment can be adjusted in real-time according to the weight changes of the titanium alloy to reduce the influence of the surrounding environment on the titanium alloy, thereby reducing cutting deviations and improving cutting accuracy.

[0114] As the device embodiment is basically similar to the method embodiment, the description is relatively simple, and relevant parts can be found in the description of the method embodiment.

[0115] Reference Figure 2 The diagram shows a structural block diagram of a titanium alloy cutting control device according to an embodiment of this application.

[0116] Specifically, it includes:

[0117] The detection module 201 is used to detect the initial weight value of the titanium alloy after it is submerged in the cutting water tank and to calculate the initial stress value using the initial weight value.

[0118] The calculation module 202 is used to determine the weight value of the residue in the cutting water tank after the cutting equipment is started to cut the titanium alloy in the cutting water tank, and to calculate the real-time weight value of the titanium alloy using the weight value of the residue.

[0119] The control module 203 is used to calculate the weight difference based on the initial force value and the real-time weight value, and to determine the cutting parameters based on the magnitude of the weight difference, so as to control the cutting equipment to cut the titanium alloy using the cutting parameters.

[0120] Optionally, determining the weight of the residue in the cutting tank includes:

[0121] The first inspection image was taken from the bottom of the cut water tank;

[0122] The first detection image is subjected to residue identification to obtain a residue area image, which is an image of fine titanium alloy residue deposited in the corresponding area of ​​the cutting water tank.

[0123] After calculating the area of ​​the image of the residue region to obtain the area value, the weight value corresponding to the area value is calculated according to the preset first image conversion ratio to obtain the weight value of the residue.

[0124] Optionally, determining the cutting parameters based on the weight difference includes:

[0125] If the cutting equipment is a high-pressure water cutter, then calculate the change in water volume in the cutting water tank. The change in water volume is the difference between the water volume of the cutting water tank before the titanium alloy was placed and the water volume of the cutting water tank at the current time point.

[0126] If the weight difference is greater than the preset first weight value and the water volume change value is greater than the preset water volume value, then the current water capacity of the cutting water tank is adjusted to the water capacity before the titanium alloy is placed, the weight ratio of the weight difference to the initial weight value is calculated, and the output water pressure value of the cutting equipment is reduced according to the weight ratio to obtain the cutting parameters.

[0127] If the weight difference is less than a preset first weight value and the water volume change is less than a preset water volume value, then the current output water pressure value of the cutting device is obtained to get the cutting parameters;

[0128] If the weight difference is greater than a preset first weight value and the water volume change is less than a preset water volume value, then the weight ratio of the weight difference to the initial weight value is calculated, and the output water pressure of the cutting device is reduced by multiplying the weight ratio by a preset first weight coefficient to obtain the cutting parameters.

[0129] Optionally, determining the weight of the residue in the cutting tank includes:

[0130] A second detection image is taken from the side of the cut water tank. Particle identification is performed on the second detection image to obtain multiple images of residue particles. Each image of residue particles is an image of titanium alloy granular residue deposited on the cut water tank.

[0131] After calculating the area of ​​each of the residue particle images to obtain the particle area value, the sum of the multiple particle area values ​​is calculated, and the weight value corresponding to the sum value is calculated according to the preset second image conversion ratio to obtain the residue weight value.

[0132] Optionally, determining the cutting parameters based on the magnitude of the weight difference, and using the cutting parameters to control the cutting equipment to cut the titanium alloy, includes:

[0133] If the cutting equipment is a plasma cutter, the number of residue particles in multiple images is counted to obtain the residue particle quantity value;

[0134] If the weight difference is less than a preset second weight value and the number of residue particles is less than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and increase the output power of the cutting equipment based on the weight ratio to obtain the cutting parameters;

[0135] If the weight difference is greater than a preset second weight value and the number of residue particles is greater than a preset number value, then calculate the weight ratio of the weight difference to the initial weight value, and reduce the output power of the cutting equipment by multiplying the weight ratio by the preset second weight coefficient to obtain the cutting parameters;

[0136] If the weight difference is greater than a preset second weight value and the number of residue particles is less than a preset number value, then the current output power of the cutting equipment is obtained to get the cutting parameters.

[0137] Optionally, the device further includes:

[0138] The time acquisition module is used to acquire the cutting time of titanium alloy;

[0139] The alarm enhancement module is used to send an alarm notification to the user if the cutting time exceeds a preset time.
