Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Example 1: See Figures 1 to 6The present invention discloses a plasma cutting device for processing aluminum alloy sheets, comprising a support frame 1, a support frame 2 centrally mounted on the upper end of the support frame 1, and a slag discharge port penetrating between the support frame 1 and the support frame 2. A slag collection mechanism is installed inside the support frame 2, and moving mechanisms are arranged on both sides of the support frame 2. A cutting mechanism is fixedly connected between the moving mechanisms. The support frame 1, support frame 2, slag discharge port, slag collection mechanism, moving mechanisms, and cutting mechanisms facilitate the construction of the overall frame of the aluminum alloy sheet plasma cutting device, realizing sheet support, slag discharge and collection, and providing a basic structure for the movement and cutting operation of the cutting mechanism. The moving mechanism includes racks 14 fixedly connected to the lower ends of both sides of the support frame 2, guide rails 3 fixedly connected to the upper ends of both sides of the support frame 2, sliding blocks 15 slidably mounted on the guide rails 3, and a first sliding block 15 fixedly connected to the other end of the sliding block 15. The first movable seat 4 is equipped with a servo motor 12. The output end of the servo motor 12 is coaxially fixed to a drive gear 13. The drive gear 13 meshes with a rack 14. Through the rack 14, guide rail 3, sliding block 15, first movable seat 4, servo motor 12, and drive gear 13, the servo motor 12 can drive the drive gear 13 to mesh with the rack 14, causing the first movable seat 4 to slide along the guide rail 3, thereby realizing the lateral position adjustment of the cutting mechanism to adapt to the cutting needs of different sized plates. The upper end of the first movable seat 4 is fixedly connected to a fixed column 5, and a fixed plate 6 is fixedly connected between the fixed columns 5. Through the fixed columns 5, fixed plate 6, and first movable seat 4, the first movable seats 4 on both sides can be connected to form a stable lateral support structure, providing a stable carrier for the installation and movement of the cutting mechanism and ensuring the stability of the structure during the cutting process.

[0017] In this invention, the cutting mechanism includes a second movable seat 7 movably mounted on a fixed plate 6. A linear motor is vertically mounted on one side of the second movable seat 7, and a lifting seat 9 is mounted on the linear motor. A cutting gun 10 is mounted on the lifting seat 9 via bolts and a fixing ring. A connecting wire 8 connects the top of the cutting gun 10 to the second movable seat 7. Through the second movable seat 7, the linear motor, the lifting seat 9, the cutting gun 10, and the connecting wire 8, the lateral and vertical positions of the cutting gun 10 can be easily adjusted. The cutting gun 10 enables plasma cutting of aluminum alloy sheets. The connecting wire 8 ensures the power supply or signal transmission of the cutting gun 10, ensuring normal cutting function. Support plates 11 are equidistantly installed between the support frames 2, and a [missing information - likely a device or mechanism] is fixedly connected in the middle between the support frames 2. The triangular blocking block 17, along with the support plate 11, triangular blocking block 17, and support frame 2, facilitates the support of the aluminum alloy sheet to be cut, preventing the sheet from sinking during the cutting process. The residue collection mechanism includes a slag discharge plate 16 symmetrically hinged to the lower end of the support plate 11. A vibrator 20 is installed at the bottom of the slag discharge plate 16, and a guide post 19 is fixedly connected to the bottom of the slag discharge plate 16. A telescopic spring 18 is sleeved on the guide post 19. Through the slag discharge plate 16, vibrator 20, guide post 19, and telescopic spring 18, the residue generated by plasma cutting is easily collected. The vibrator 20 can drive the slag discharge plate 16 to vibrate, assisting the residue to slide down the slag discharge plate 16 to the slag discharge port. The telescopic spring 18 assists the slag discharge plate 16 to reset, ensuring the smooth collection and discharge of residue.

[0018] Working principle: When using the plasma cutting device for aluminum alloy sheet processing of the present invention, the aluminum alloy sheet to be cut is first placed on the support plate 11 inside the support frame 2. The support plate 11 provides stable support for the sheet, and the triangular blocking block 17 in the middle of the support frame 2 prevents the sheet from sinking during the cutting process, ensuring that the sheet is flat and without warping. Next, according to the thickness requirements of the sheet, the height of the lifting seat 9 is adjusted by the linear motor installed vertically on one side of the second moving seat 7, so that the cutting gun 10, which is installed on the lifting seat 9 by bolts and fixing rings, is aligned with the sheet. Maintain a 5mm distance from the material surface to ensure cutting effect; then, according to the cutting trajectory requirements, activate the servo motor 12 below the first moving seat 4, causing the drive gear 13 coaxially fixed to the output end of the servo motor 12 to mesh with the racks 14 at the lower ends of both sides of the support frame 2, driving the first moving seat 4 to slide along the guide rails 3 at the upper ends of both sides of the support frame 2 via the sliding block 15, thereby realizing the lateral position adjustment of the cutting mechanism. At the same time, the second moving seat 7 sleeved on the fixed plate 6 can be moved (the fixed plate 6 is fixed to the first moving seats 4 on both sides via the fixed column 5 to form a stable support). (Support) Further adjust the lateral position of the cutting torch 10 to ensure that the cutting torch 10 is aligned with the cutting starting point; then, start the plasma power supply, and ensure power supply or signal transmission through the connecting wire 8 between the second moving seat 7 and the top of the cutting torch 10, so that the cutting torch 10 generates a plasma arc, and then performs plasma cutting on the plate; during the cutting process, the molten slag generated falls from the gap between the support plates 11, first falling on the triangular blocking block 17, and then being guided by the triangular blocking block 17 to roll onto the slag discharge plate 16 symmetrically hinged at the lower end of the support plate 11; at the same time, start the bottom of the slag discharge plate 16. The vibrator 20 installed in the part drives the slag discharge plate 16 to vibrate, causing the residue to slide down the inclined surface of the slag discharge plate 16. The telescopic spring 18 sleeved on the guide column 19 fixed to the bottom of the slag discharge plate 16 assists the slag discharge plate 16 to return to its original position during the vibration process, ensuring that the residue can be smoothly discharged through the slag discharge port opened in the middle between the support frame 1 and the support frame 2, and finally fall into the waste collection device below the device. After the cutting is completed, the plasma power supply, servo motor 12, linear motor and vibrator 20 are turned off, and the cut plate is removed from the support plate 11 to complete the entire cutting operation.

[0019] Example 2: See Figure 7 The control box of the cutting device is equipped with an intelligent control component, which includes an analysis module and an adjustment module. The analysis module receives and preprocesses the acquired slag parameter data, plasma parameter data, plate parameter data, and vibration parameter data, removing outliers. Based on the preprocessed data, it analyzes the amount of slag generated during cutting and the amount of slag discharged. If the amount of slag exceeds the amount of slag discharged, a positive vibration adjustment signal is generated and transmitted to the adjustment module. The module also analyzes the noise level based on the vibration parameter data and adjusts the vibration amplitude and frequency based on their relationship. Preprocessing: The collected data is sorted according to the collection time, and corresponding items collected at the same time are processed. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated. The calculation, and the mean obtained from the calculation. As the corresponding data detected at the corresponding time; Slag is formed by the cooling of molten metal that was not blown away by the plasma gas, i.e., the amount of slag. Total molten metal The amount of molten metal blown away by the airflow Total molten metal The values ​​are determined by "plasma arc heat input" and "melting volume of the plate". "Decision, that is" ,in The density of aluminum alloy, , and These are the data for plate thickness, slit width, and slit length, respectively; the amount of molten metal blown away is positively correlated with "plasma gas blowing force" and "molten metal flowability," that is... ,in The slag removal coefficient is related to the type of plasma gas. This refers to the plasma gas flow rate. For cutting speed, The plasma arc energy density; in summary, the amount of molten slag , The correction factor is related to alloy composition, surface oxide scale, and arc column stability; Correction coefficient The 6xxx series alloys contain >5% Mg and Si, with a correction factor. For alloys in the 2xxx series, the Cu content is >4%, with a correction factor. For common aluminum alloys that do not belong to the above two categories, the correction factor is... Surface oxide layer thickness > 5 μm, correction factor Surface oxide layer thickness <2μm, correction factor ; Curved column stability > 0.9, correction factor ; Curved column stability <0.7, correction factor .

[0020] The amount of slag produced is determined based on the parameters of the plate and the plasma arc; the amount of slag discharged is related to the viscosity of the slag. Vibration amplitude and vibration frequency The higher the viscosity, the greater the force required to break the adhesion, and this is negatively correlated with the slag discharge rate. The greater the vibration amplitude and frequency, the greater the kinetic energy transferred to the molten slag, making it easier to break and detach. In vibration theory, the acceleration generated by vibration is proportional to the square of the frequency; the greater the acceleration, the greater the force required to break the adhesion, and thus the greater the slag discharge rate. If the amount of slag produced per unit time Slag discharge volume greater than the unit time If the signal is positive, a positive vibration adjustment signal is generated and transmitted to the adjustment module; otherwise, a negative vibration adjustment signal is generated and transmitted to the adjustment module. Before transmitting the positive vibration adjustment signal to the adjustment module, the analysis module analyzes the viscosity data of the current molten slag. The average viscosity data of the slag was obtained and analyzed against historical data. If a comparison is made, If the vibration amplitude is high, then the priority is to increase the vibration amplitude, and the corresponding priority signal is transmitted to the adjustment module; otherwise, the priority is to increase the vibration frequency, and the corresponding priority signal is transmitted to the adjustment module. Viscous data is then searched for in historical data. The same vibration amplitude and vibration frequency data are used as the final adjustment value. If the corresponding vibration amplitude and vibration frequency data are not found in the historical data, the final adjustment value of the corresponding data is determined according to the data pattern. After receiving positive / negative vibration adjustment signals, the adjustment module adjusts the vibration amplitude or frequency according to the priority signal transmitted by the analysis module; Vibration during slag removal operations generates noise. The amplitude is positively correlated with the noise level, and the radiation efficiency of the vibration increases with frequency. In many practical cases, noise is proportional to the square or higher powers of the frequency. , These are empirical constants; Obtain historical data, and substitute the slag discharge volume, noise level, slag viscosity, vibration amplitude, and vibration frequency from the historical data into the formulas for slag discharge volume and noise level, respectively, to obtain the proportional coefficients for the corresponding formulas. , ,but , ; When vibration is primarily transmitted through solid structures (such as the mechanical vibration transmission between a slag discharge plate and a support frame), the energy transfer of vibration in the solid is significantly related to the square or cube of the frequency, and empirical constants are used. When vibration primarily transmits sound through air disturbance (such as vibration-induced airflow turbulence noise), the energy of the airflow turbulence noise is correlated with a high power of the vibration velocity, while the vibration velocity is positively correlated with the product of frequency and amplitude, an empirical constant. When equipment experiences multi-frequency vibration superposition (such as vibration coupling between a vibrator and a cutting mechanism), the interaction of vibration components of different frequencies causes the frequency response of noise to exhibit nonlinear superposition. The dependence of noise on frequency will lie between the square and the cube, and the empirical constant... When damping materials or sound insulation structures are used (such as damping alloys used in slag discharge plates), the damping materials absorb high-frequency vibration energy, reducing the noise's sensitivity to high frequencies. (Empirical constant) ; Adjustment amount of vibration amplitude Adjustment amount of vibration frequency satisfy: The derivation yields That is, when the amplitude of vibration is and vibration frequency is At that time, regarding the amplitude of vibration and vibration frequency When making adjustments, the amount of vibration amplitude adjustment Adjustment amount of vibration frequency satisfy: This means that while maintaining the same amount of slag discharge, the noise level can be reduced by lowering the vibration frequency.
