[0002] Electrolytic machining is a form of contour machining of metallic workpieces, utilizing an electrolytic system consisting of a forming cathode, a conductive anode, an electrolyte, and a power source. The cathode receives charge from the power source, continuously dissolving the anode. This process includes, but is not limited to, machining of thin-walled parts with irregularly shaped holes, 3D surface copying, complex cavity forming, blind hole expansion, and constant-section sleeve machining, among other workpiece forming processes. Currently, in practical applications, most machine tool programmable control systems (PLCs) use fixed, single-pulse parameters by default, resulting in low intelligence and poor workpiece machining quality stability.

When the second electrolytic machine tool is assembled on one side of the first electrolytic machine tool, it cooperates with the first electrolytic machine tool to electrolytically process the workpieces at the multiple workstations.

[0007] Three positive and negative pulse combination types are configured. One of the three positive and negative pulse combination types is selected according to the electrolyte state and the workpiece processing complexity to control the first electrolytic machine tool and the second electrolytic machine tool to perform electrolytic processing on the workpieces at the multiple workstations.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] Example 1

[0021] See Figures 1-5 This embodiment provides an electrolysis method based on a machine tool programmable control system, including:

[0022] S101. Configure three positive and negative pulse combination types, which correspond to different electrolyte states and workpiece processing complexity.

[0023] S102. Based on the electrolyte state and the workpiece processing complexity, select one of the three positive and negative pulse combination types that is compatible with the electrolyte state and the workpiece processing complexity;

[0024] S103. Based on the selected positive and negative pulse combination type that adapts to the electrolyte state and the workpiece processing complexity, control the first electrolytic machine tool and the second electrolytic machine tool to perform electrolytic processing on the workpieces at multiple workstations; the first electrolytic machine tool and the second electrolytic machine tool are set separately, the first electrolytic machine tool is set with the multiple workstations, and when the second electrolytic machine tool is assembled to one side of the first electrolytic machine tool, it cooperates with the first electrolytic machine tool to perform electrolytic processing on the workpieces at the multiple workstations.

[0025] It should be noted that in this embodiment, three positive and negative pulse combination types are configured, each corresponding to different electrolyte states and workpiece processing complexities. Based on the electrolyte state and workpiece processing complexity, one of the three positive and negative pulse combination types is selected to suit both. According to the selected suitable positive and negative pulse combination type, the first and second electrolytic machine tools are controlled to perform electrolytic processing on workpieces at multiple workstations. The first and second electrolytic machine tools are separately configured. The first electrolytic machine tool has the multiple workstations. When the second electrolytic machine tool is assembled to one side of the first electrolytic machine tool, it cooperates with the first electrolytic machine tool to perform electrolytic processing on the workpieces at the multiple workstations, thereby realizing multi-workstation workpiece electrolytic processing. Furthermore, the second and first electrolytic machine tools can be used in combination or separately, greatly reducing electrolysis costs. In addition, the configuration and selection of three positive and negative pulse combination types can improve the intelligence level of workpiece electrolytic machining and enhance the quality stability of workpiece machining.

[0026] In some preferred embodiments, after selecting one of the three positive and negative pulse combination types, the power supply of the first electrolytic machine tool is controlled to provide positive pulses to the workpieces at the multiple workstations, and / or the power supply of the second electrolytic machine tool is controlled to provide positive pulses to the workpieces at the multiple workstations, for electrolytic machining of the workpieces at the multiple workstations. During the machining process, a preset time period is selected to control the power supply of the first electrolytic machine tool to provide negative pulses to the workpieces at the multiple workstations, and / or the power supply of the second electrolytic machine tool to provide negative pulses to the workpieces at the multiple workstations, for repairing the electrodes of the first and second electrolytic machine tools. It should be noted that during the electrolysis process, the positive and negative terminals of the power supply are connected to the workpiece and the electrode, respectively, forming an electrolytic circuit. After the electrode has been electrolytically machining the workpiece for a long time, residues generated by the workpiece will adhere to the electrode surface, causing a decrease in machining accuracy. In this embodiment, during the processing, a preset time period is selected to control the power supply of the first electrolytic machine tool to provide negative pulses to the workpieces at the multiple workstations, and / or control the power supply of the second electrolytic machine tool to provide negative pulses to the workpieces at the multiple workstations, thereby repairing the electrodes of the first electrolytic machine tool and the second electrolytic machine tool, thereby eliminating residues on the electrodes and improving the processing accuracy of the workpieces.

[0027] In some preferred embodiments, the electrode repair time for repairing the electrodes of the first and second electrolytic machines is less than the workpiece processing time for electrolytic machining of the workpieces at the multiple workstations; the negative pulse voltage value for repairing the electrodes of the first and second electrolytic machines is less than the positive pulse voltage value for electrolytic machining of the workpieces at the multiple workstations. It should be noted that if the electrode repair time is longer than the workpiece processing time, the electrolytic machine will be unable to continue workpiece processing during the repair period, thereby increasing downtime and reducing equipment utilization and overall processing efficiency. Therefore, designing the electrode repair time to be shorter than the workpiece processing time can maximize equipment uptime, completing electrode maintenance as quickly as possible while completing workpiece electrolytic machining, ensuring the continuity of the processing process. By shortening the electrode repair time, good synchronization with the workpiece processing time can be achieved, allowing for seamless integration of repair and processing, ensuring the equipment operates efficiently in each work cycle, reducing workpiece waiting time at the processing station, and improving overall output. When repairing the electrodes, the negative pulse is mainly used to remove residues adhering to the electrode surface; this process does not require the high voltage required for workpiece machining. Designing the negative pulse voltage to be lower than the positive pulse voltage effectively cleans the electrode without generating excessive electrochemical reactions, avoiding unnecessary interference with surrounding workpieces and the processing environment. The lower negative pulse voltage helps reduce the impact on the electrode itself, thus extending its lifespan. Maintaining electrode surface cleanliness also reduces electrode wear rate, decreasing equipment maintenance and replacement costs. Using a lower negative pulse voltage for electrode repair than the positive pulse voltage during processing also meets energy-saving requirements. By reducing power consumption during electrode repair, energy costs can be lowered while ensuring repair effectiveness, improving the overall economic efficiency of the equipment.

[0028] In further preferred embodiments, when selecting the positive and negative pulse combination type based on the electrolyte state and workpiece processing complexity, type A positive and negative pulse combination type is selected when the electrolyte pH is neutral; type B positive and negative pulse combination type is selected when the electrolyte pH is weakly acidic; and type C positive and negative pulse combination type is selected if the workpiece processing complexity falls within a preset complexity range. The number and occurrence sequence of positive and negative pulses differ in the type A, type B, and type C positive and negative pulse combination types. It should be noted that when the electrolyte pH is neutral, this environment is suitable for a mild electrolysis process, therefore type A positive and negative pulse combination type is selected. Type A positive and negative pulse combination type includes a preset small number of negative pulses, and the interval between positive and negative pulses is a preset large interval, ensuring that the workpiece processing can proceed smoothly in a neutral environment, avoiding excessive electrolysis reactions that could lead to over-removal or damage to the workpiece surface. For example: 5 positive pulses followed by 1 negative pulse, each positive pulse lasting 2 seconds and each negative pulse lasting 0.5 seconds, with a cycle of 12 seconds. In this mode, the negative pulses are fewer and shorter, suitable for gentle electrolysis in a neutral electrolyte environment. Additionally, when the electrolyte is weakly acidic, type B pulse combination is selected. The intensity of the electrolytic reaction is correspondingly increased; therefore, type B pulse combination contains more negative pulses than type A positive-negative pulse combination, and the frequency of negative pulses is higher, while the interval between positive and negative pulses is shorter. This setting ensures effective control of the processing cycle and allows for timely electrode repair. For example: 2 positive pulses followed by 2 negative pulses, each positive and negative pulse lasting 1 second, with a cycle of 8 seconds. This rapid pulse alternation controls the processing rate and protects the workpiece and electrodes. Furthermore, when the workpiece's processing complexity falls within a preset complexity range, type C positive-negative pulse combination is selected. The complexity of the workpiece determines the accuracy and control requirements of the electrolysis process. The C-type combination includes a preset pulse timing sequence, such as frequent alternation of positive and negative pulses, to ensure good surface finish and machining accuracy during highly complex processing. For example, one positive pulse is followed by one negative pulse, each positive pulse lasting 1.5 seconds and the negative pulse lasting 1 second, with a cycle of 5 seconds. This mode is more suitable for the fine machining of complex workpieces, ensuring uniform surface electrolysis during processing and achieving precise control. It is important to note that in this embodiment, the pulse type is selected based on the pH value of the electrolyte and the complexity of the workpiece, allowing for optimization for different processing environments and workpiece characteristics. This personalized processing method improves the adaptability and flexibility of the electrolysis process. By optimizing the frequency and timing of positive and negative pulses, the consistency and accuracy of the workpiece surface can be maintained under different processing conditions. Simultaneously, appropriately setting the frequency and timing of negative pulses can effectively and promptly repair the electrode, extending its service life.At the same time, by precisely controlling the timing of the pulses, the intensity of the electrolytic reaction can be precisely controlled, ensuring the consistency of processing accuracy and processing quality.

[0029] In some preferred embodiments, the first electrolytic machine tool 1 includes a planar workpiece station 11, a curved workpiece station 12, and a gantry electrolytic electrode mechanism 13 located above the planar workpiece station 11 and the curved workpiece station 12, all disposed on a first machine base 10. The gantry electrolytic electrode mechanism 13 is used to electrolytically process the front surface of the planar workpiece on the planar workpiece station 11 and to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12. When the second electrolytic machine tool 2 is assembled to one side of the curved workpiece station 12, it cooperates with the first electrolytic machine tool 1 to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12.

[0030] It should be noted that in this embodiment, the first electrolytic machine tool 1 and the second electrolytic machine tool 2 are independent units and can be used individually or in combination. The split design increases the flexibility and adaptability of the equipment; different workpieces can be processed using suitable electrolytic machine tools, or they can be used in combination, expanding the equipment's application range. Furthermore, the first electrolytic machine tool 1 is equipped with a planar workpiece station 11 and a curved workpiece station 12, and also features a gantry electrolytic electrode mechanism 13. This configuration allows the same machine tool to handle different types of workpieces, including planar and curved workpieces. This not only improves the equipment's versatility but also makes the processing more efficient, reducing equipment changeover and workpiece positioning time. The gantry electrolytic electrode mechanism 13 is designed to perform electrolytic machining on both planar and curved workpieces on the same machine tool: machining the front of planar workpieces while also processing the sidewalls of curved workpieces. This design fully utilizes equipment space and reduces the need for station adjustments and tooling changes when processing different workpieces, thus improving processing efficiency. Furthermore, when the second electrolytic machine tool 2 is assembled to one side of the curved workpiece station 12 of the first electrolytic machine tool 1, it can cooperate with the first electrolytic machine tool 1 to jointly complete the electrolytic machining of the sidewall of the curved workpiece. This collaborative machining method enables efficient machining of complex workpieces when needed. Since the second electrolytic machine tool 2 is independent, it can not only cooperate with the first electrolytic machine tool 1, but also be used in combination with other electrolytic machine tools. This modular combination method further reduces the overall operating cost of the electrolysis equipment.

[0031] In some preferred embodiments, the workpieces electrolytically processed at the planar workpiece station 11 include thin-plate shaped workpieces, while the workpieces electrolytically processed at the curved workpiece station 12 include disc-shaped and cylindrical workpieces. It should be noted that thin-plate shaped workpieces typically have large and flat surfaces, making them suitable for electrolytic processing at planar stations. Disc-shaped and cylindrical workpieces have curved surfaces, which require specific electrode mechanisms for processing to ensure uniform electrolyte distribution and stable electrolytic current. The curved workpiece station 12 is designed to meet this requirement; its electrode mechanism can adapt to different curved surface shapes, thereby ensuring high-quality electrolytic results during processing. For example, the planar workpiece station 11 can employ a planar electrode design to make the electrolytic processing area more uniform; while the curved workpiece station 12 can employ arc-shaped or ring-shaped electrodes to better fit and cover the sidewalls of the disc or cylindrical workpiece, achieving optimal electrolytic results.

[0032] In some preferred embodiments, the planar workpiece station 11 is provided with a planar electrolysis platform 14. The planar electrolysis platform 14 is located on the table surface of the first machine tool 10 and is used to place the planar workpiece for electrolytic processing of its front surface by the gantry electrolysis electrode mechanism 13. It should be noted that planar workpieces typically require high stability and positioning accuracy during processing. The planar electrolysis platform provides a stable surface for the workpiece, ensuring it does not move or shift during processing, thereby improving processing accuracy. Simultaneously, the planar electrolysis platform 14 not only provides a stable surface for placing the workpiece but also helps optimize electrolyte flow. During electrolytic processing, the electrolyte needs to uniformly cover the surface of the workpiece to ensure the uniformity of the electrolytic reaction. The planar platform makes it easier to control the electrolyte flow path, allowing the electrolyte to be evenly distributed on the workpiece surface, thereby improving the electrolysis effect. Furthermore, since the gantry electrolysis electrode mechanism 13 electrolytically processes the planar workpiece from above, the workpiece needs to remain stable and exposed within the working area of ​​the electrode mechanism during processing. Placing the workpiece on a planar electrolysis platform, located on the table of the first machine tool 10, ensures that the workpiece is always within the effective working area of ​​the gantry electrolysis electrode mechanism 13.

[0033] In some preferred embodiments, the curved workpiece station 12 is provided with an electrolytic machining turntable 15; the electrolytic machining turntable 15 is located on the table surface of the first machine tool 10 and is situated on one side of the planar electrolytic platform 14, for placing the curved workpiece to await electrolytic machining of the side surface of the curved workpiece by the gantry electrolytic electrode mechanism 13. Further, the electrolytic machining turntable 15 includes a support platform 150 and a column turntable 151; the support platform 150 is disposed on the table surface of the first machine tool 10; the column turntable 151 is disposed on the support platform 150, for placing the curved workpiece to await electrolytic machining of the side surface of the curved workpiece by the gantry electrolytic electrode mechanism 13; during electrolytic machining, the column turntable 151 rotates on the support platform 150 at a preset rotation angle, allowing different positions on the side surface of the curved workpiece to undergo electrolytic machining. It should be noted that the side of a curved workpiece (such as a disc-shaped or cylindrical workpiece) is a circular surface, and an electrolytic electrode at a single location cannot cover the entire side at once. By setting up a cylindrical turntable 151, the workpiece can be rotated during electrolytic machining, allowing the gantry electrolytic electrode mechanism 13 to gradually cover different positions on the side of the curved workpiece, achieving uniform electrolytic machining from all directions. The design of the electrolytic machining turntable 15 enables the equipment to handle curved workpieces of different shapes and sizes. The combination of the support platform 150 and the cylindrical turntable 151 allows for adjustment of the support and fixing methods, adapting to the placement and fixing requirements of various curved workpieces.

[0034] In some preferred embodiments, the second electrolytic machine tool 2 includes a second machine base 20 and an electrolytic machining mechanism 21, the electrolytic machining mechanism 21 being disposed on the second machine base 20. When the second electrolytic machine tool 2 is assembled to one side of the curved workpiece station 12, the electrolytic machining mechanism 21, in conjunction with the first electrolytic machine tool 1, performs electrolytic machining on the sidewall of the curved workpiece on the curved workpiece station 12. It should be noted that the independent design of the second electrolytic machine tool 2 allows it to be flexibly used in conjunction with the first electrolytic machine tool 1 or independently. This modular design allows the equipment to be freely combined according to actual processing needs, thereby expanding the equipment's processing adaptability. When the second electrolytic machine tool 2 cooperates with the first electrolytic machine tool 1, the sidewall of the curved workpiece can be processed simultaneously. This simultaneous processing method can significantly shorten processing time and improve production efficiency. For example, when processing large curved workpieces, relying solely on one electrolytic machine tool may require a long time to complete the processing. However, by introducing the second electrolytic machine tool 2, electrolytic machining can be performed simultaneously on different parts, thereby improving the overall production speed and efficiency. For some complex curved workpieces, it may be difficult to achieve uniform electrolytic machining using only one electrode. However, by setting up a second electrolytic machine tool 2, additional electrolytic machining mechanisms 21 can be placed at different positions and work synchronously with the electrodes of the first electrolytic machine tool 1 to ensure that every part of the workpiece receives uniform electrolytic machining.

[0035] In some preferred embodiments, the electrolytic machining mechanism 21 includes a Y-axis moving block 210 and an electrolytic machining component 211; the electrolytic machining component 211 is movably connected to the Y-axis moving block 210; the Y-axis moving block 210 is disposed on the second machine table 20 and movably connected to the table surface of the second machine table 20; the Y-axis moving block 210 drives the electrolytic machining component 211 to move along the Y-axis direction on the table surface of the second machine table 20; the electrolytic machining component 211 moves or moves away from the curved workpiece station 12 on the Y-axis moving block 210; the direction of the curved workpiece station 12 is the X-axis direction. Furthermore, the electrolytic machining assembly 211 includes a Z-axis drive module 2110 and an electrode electrolysis device 2111; the electrode electrolysis device 2111 is mounted on the Z-axis drive module 2110 and moves along the Z-axis direction under the drive of the Z-axis drive module 2110; the Z-axis drive module 2110 is movably connected to the Y-axis moving block 210. Furthermore, the electrode electrolysis device 2111 includes a Z-axis drive connecting block 21110 and a sidewall electrolysis turntable 21111; the Z-axis drive connecting block 21110 is connected to the Z-axis drive module 2110, and the sidewall electrolysis turntable 21111 is connected to the Z-axis drive connecting block 21110; electrodes are disposed on the sidewall electrolysis turntable 21111; during electrolytic machining, the sidewall electrolysis turntable 21111 rotates on the Z-axis drive connecting block 21110 at a preset rotation angle, so that different positions on the side of the curved workpiece are subjected to electrolytic machining. It should be noted that by introducing a Y-axis moving block 210 and a Z-axis drive module 2110 into the electrochemical machining mechanism 21, the equipment can move in multiple axes, thereby precisely positioning the electrode. This design ensures that the electrode can be adjusted according to the shape and size of the workpiece, adapting to the machining requirements of different curved workpieces. Under the action of the Y-axis moving block 210, the electrochemical machining component 211 can move along the Y-axis to cover different workstation positions or adjust the machining path; the Z-axis drive module 2110 allows the electrode to be adjusted up and down along the Z-axis to adapt to changes in the height of the workpiece sidewall, achieving high-precision machining. The multi-axis movement design enables the electrochemical machining mechanism 21 to precisely control the position and angle of the electrode. The Z-axis drive module 2110 can precisely adjust the distance between the electrode and the workpiece surface, thereby ensuring the consistency of the electric field strength and electrolyte distribution during the electrolysis process, improving machining accuracy. Through the combined adjustment of the Y-axis and Z-axis, the electrode can move along different paths and directions, which is particularly important for curved workpieces with complex geometries, helping to achieve high-precision machining results. The movable connection between the Y-axis moving block 210 and the electrolytic processing component 211 allows the entire mechanism to be flexibly adjusted in position on the second machine tool 20.This design enables automated processing, automatically adjusting electrode positions according to different processing tasks to improve production efficiency. Driven by the Z-axis drive module 2110, the electrode electrolysis device 2111 can flexibly handle workpieces of varying heights and shapes. This flexibility not only enhances the equipment's adaptability but also facilitates future equipment upgrades and the diversification of processing tasks. Electrodes are mounted on the sidewall electrolysis turntable 21111, which rotates at a preset angle on the Z-axis drive connecting block 21110 during electrolysis. This design ensures that the electrodes conform to the curvature and shape of the curved workpiece, gradually covering the sidewall surface and ensuring a uniform electrolysis process.

[0036] In some preferred embodiments, the gantry electrolytic electrode mechanism 13 includes a gantry 130 and a suspended electrolytic device 131. The gantry 130 is mounted on the table of the first machine tool 10. The suspended electrolytic device 131 is suspended on the gantry 130 and is used for electrolytic machining of the front surface of the flat workpiece at the flat workpiece station 11, and also for electrolytic machining of the side wall of the curved workpiece at the curved workpiece station 12. It should be noted that the design of the gantry electrolytic electrode mechanism 13 enables it to process different types of workpieces on the same equipment. The suspended electrolytic device 131 can process the front surface of the flat workpiece and can also adjust its height and position to process the side wall of the curved workpiece. In this way, one device can complete multiple processing tasks, reducing the need for multiple devices, thereby improving equipment utilization and the overall efficiency of the production line. The suspended electrolytic device 131, by being mounted on the gantry 130, can move along the track of the gantry 130 and adjust its position and height. This design allows the electrolysis unit to move flexibly in multiple directions (X, Y, Z), enabling precise alignment with the workpiece's processing area. Whether it's the front of a flat workpiece or the sidewall of a curved workpiece, accurate positioning and processing can be achieved. The gantry 130, mounted on the table of the first machine tool 10, provides a stable support structure for the suspended electrolysis unit 131, ensuring the stability and accuracy of the electrodes during processing.

Furthermore, the second and first electrolysis machine tools can be used in combination or separately, greatly reducing electrolysis costs. In addition, the configuration and selection of three positive and negative pulse combination types can improve the intelligence level of workpiece electrolytic machining and enhance the quality stability of workpiece machining.
