Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic processing, and more particularly to an electrolytic device and an electrolytic method. BACKGROUND

[0002] Pipe electrode electrolytic processing is a processing method that uses a hollow pipe as a cathode to electrochemically dissolve the anode of a workpiece. Generally, the electrolyte is sprayed from the bottom end face of the pipe electrode, collides with the processed bottom face, and is reflected to the gap between the pipe electrode and the workpiece, thereby dissolving the anode of the workpiece. When electrolytic milling of the middle part of the workpiece is required, a punching pipe electrode is used to punch the workpiece, and then a milling pipe electrode is used to mill the workpiece again, which is a cumbersome operation.

[0003] At the same time, in the processing process, there are problems of joule heat and difficulty in discharging electrolysis products, and the electrolyte is easy to accumulate on the surface of the workpiece, causing serious stray corrosion, thereby affecting the processing efficiency and processing quality. Especially as the aspect ratio increases, the electrolyte pressure along the way also increases, the flow rate rapidly decreases, and the electrolysis products are more likely to accumulate, eventually causing sparking or even short circuit, which seriously reduces the processing stability and processing quality. SUMMARY

[0004] The purpose of the present application is to overcome the deficiencies of the prior art, such as the cumbersome operation of electrolytic milling of the middle part of the workpiece and the low efficiency of discharging electrolysis products, causing stray corrosion, and to provide an electrolytic device and an electrolytic method, which facilitates electrolytic milling of the middle part of the workpiece, improves the efficiency of discharging electrolysis products, and reduces the stray corrosion area on the surface of the workpiece.

[0005] To solve the above technical problems, the technical solution adopted by the present application is:

[0006] The application provides an electrolysis device, which comprises a mounting table, a vertical moving mechanism, a first electrolyte tank, a first liquid pump, a second liquid pump, a power supply, a horizontal moving mechanism, a clamp and an electrolysis tube electrode, wherein the electrolysis tube electrode comprises an inner layer tube, the inner layer tube is provided with a first inlet and outlet and a second inlet and outlet, the second inlet and outlet is located on the end face of the inner layer tube, the first inlet and outlet is communicated with the second inlet and outlet, the electrolysis tube electrode further comprises an outer layer tube, the outer layer tube is sleeved outside the inner layer tube, the outer layer tube is connected with the inner layer tube, the outer layer tube is provided with a third inlet and outlet and a fourth inlet and outlet, the third inlet and outlet is communicated with the fourth inlet and outlet, the fourth inlet and outlet is located on the circumferential surface of the outer layer tube; the mounting table is connected with the output end of the horizontal moving mechanism, the clamp is connected with the output end of the vertical moving mechanism, the electrolysis tube electrode is connected with the clamp, the first electrolyte tank is communicated with the first inlet and outlet through the first liquid pump, the first electrolyte tank is communicated with the third inlet and outlet through the second liquid pump, the first electrolyte tank is filled with electrolyte, and the electrolyte flows to the surface of a workpiece through the electrolysis tube electrode; the negative electrode of the power supply is electrically connected with the electrolysis tube electrode, and the positive electrode is electrically connected with the workpiece.

[0007] The electrolytic device of the present application places the workpiece on the mounting table, starts the vertical moving mechanism, the horizontal moving mechanism, the first liquid pump, the second liquid pump and the power supply, and allows the pipe electrode to approach the workpiece. When drilling, the liquid in the first electrolyte tank is extracted by the first liquid pump, enters the inner layer pipe through the first inlet and outlet port, and is sprayed towards the workpiece from the second inlet and outlet port to perform electrolytic drilling on the workpiece. At the same time, the second liquid pump sucks the electrolyte on the workpiece from the fourth inlet and outlet port into the outer layer pipe, and flows to the first electrolyte tank through the third inlet and outlet port, which can improve the product removal efficiency during drilling and reduce the stray corrosion area on the surface of the workpiece. When milling, the liquid in the first electrolyte tank is extracted by the second liquid pump, enters the outer layer pipe through the third inlet and outlet port, and is sprayed towards the workpiece from the fourth inlet and outlet port to perform electrolytic milling on the workpiece. At the same time, the first liquid pump sucks the electrolyte on the workpiece from the second inlet and outlet port into the inner layer pipe, and flows to the first electrolyte tank through the first inlet and outlet port, which can improve the product removal efficiency during milling and reduce the stray corrosion area on the surface of the workpiece. At the same time, after electrolytic drilling, electrolytic milling is directly performed, which is simple to operate. Specifically, during electrolysis, the electrolyte tank is communicated with the first inlet and outlet port and the third inlet and outlet port respectively, and the end face of the second inlet and outlet port faces the workpiece. During drilling, the electrolyte enters the inner layer pipe from the first inlet and outlet port, is sprayed towards the workpiece from the second inlet and outlet port, and is sucked back into the outer layer pipe through the fourth inlet and outlet port, and is discharged from the outer layer pipe through the third inlet and outlet port, which can improve the product removal efficiency during electrolytic drilling and reduce the stray corrosion area on the surface of the workpiece. After drilling is completed, the electrolytic pipe electrode can be used for milling operation. During milling, the electrolyte enters the outer layer pipe from the third inlet and outlet port, is sprayed towards the workpiece from the fourth inlet and outlet port, and is sucked back into the inner layer pipe through the second inlet and outlet port, and is discharged from the inner layer pipe through the first inlet and outlet port, which can improve the product removal efficiency during electrolytic milling and reduce the stray corrosion area on the surface of the workpiece. By arranging the double-layer pipe, electrolytic milling can be directly performed after electrolytic drilling, which is simple to operate. When the electrolyte flows from the inner layer pipe to the workpiece through the pipe electrode, the electrolyte on the workpiece is discharged through the outer layer pipe; when the electrolyte flows from the outer layer pipe to the workpiece through the pipe electrode, the electrolyte on the workpiece is discharged through the inner layer pipe; which can improve the product removal efficiency during electrolytic drilling and electrolytic milling, and reduce the stray corrosion area on the surface of the workpiece.

[0008] Further, the first inlet and outlet port is a square hole located at the end of the inner layer pipe and arranged in multiple along the circumference of the inner layer pipe. By arranging multiple first inlet and outlet ports, the product removal efficiency can be further improved, and the electrolytic milling efficiency can also be improved.

[0009] Further, the third inlet and outlet port is a circular ring hole formed between the outer wall of the outer layer pipe and the inner wall of the inner layer pipe. The product removal efficiency can be further improved, and the electrolytic milling efficiency can also be improved.

[0010] Further, the fourth inlet and outlet port is a square hole, located at the end of the outer tube, at the same end as the second inlet and outlet port, and a plurality of square holes are arranged along the circumference of the outer tube. The positions of the fourth inlet and outlet port and the second inlet and outlet port are close to each other, so that the electrolyte can be discharged in time, and the milling can be directly performed after drilling.

[0011] Further, the rotating motor is connected with the output end of the vertical moving mechanism, the clamp is connected with the output end of the rotating motor, and the electrolytic tube electrode is rotatably connected with the clamp. By arranging the rotating motor, the electrolytic tube electrode is driven to rotate, so that the electrolyte is sprayed more uniformly, and the product discharge efficiency is improved, so that the stray corrosion area of the workpiece surface is further reduced.

[0012] Further, the filtering mechanism and the second electrolyte tank are further arranged, the first electrolyte tank and the second electrolyte tank are communicated through the filtering mechanism, the first electrolyte tank is communicated with the first inlet and outlet port through the first liquid pump when drilling, and the second electrolyte tank is communicated with the third inlet and outlet port through the second liquid pump; when milling, the first electrolyte tank is communicated with the third inlet and outlet port through the second liquid pump, and the second electrolyte tank is communicated with the first inlet and outlet port through the first liquid pump. By arranging the second electrolyte tank, the new electrolyte is separated from the used electrolyte, so as to avoid pollution and affect the electrolysis efficiency. At the same time, by arranging the filtering mechanism, the used electrolyte is filtered and then flows into the electrolyte tank to be used, so that the electrolyte of the device can be recycled.

[0013] Further, the clamp is provided with a first inlet and outlet and a second inlet and outlet, a partition plate is arranged in the clamp, the electrolytic tube electrode is rotatably connected with the partition plate, and the partition plate divides the clamp into a first communication part and a second communication part; when drilling, the first inlet and outlet port, the first communication part, the first inlet and outlet, the first liquid pump and the first electrolyte tank are sequentially communicated, and the third inlet and outlet port, the second communication part, the second inlet and outlet, the second liquid pump and the second electrolyte tank are sequentially communicated; when milling, the first inlet and outlet port, the first communication part, the first inlet and outlet, the first liquid pump and the second electrolyte tank are sequentially communicated, and the third inlet and outlet port, the second communication part, the second inlet and outlet, the second liquid pump and the first electrolyte tank are sequentially communicated. By the clamp, the electrolytic tube electrode is rotatable and always communicated with the first electrolyte tank.

[0014] The application also provides an electrolysis method, which is realized based on the electrolysis device and includes a drilling method and a milling method.

[0015] The drilling method is as follows: the electrolyte in the first electrolyte tank enters the electrode of the electrolytic tube from the first inlet and outlet, and is sprayed onto the workpiece from the second inlet and outlet. The electrolyte on the workpiece enters the third inlet and outlet from the fourth inlet and outlet, and then flows back to the first electrolyte tank to drill holes in the workpiece.

[0016] The milling method is as follows: the electrolyte in the first electrolyte tank enters the electrolytic tube electrode through the third inlet and outlet, and is sprayed onto the workpiece through the fourth inlet and outlet. The electrolyte on the workpiece enters the electrolytic tube electrode through the second inlet and outlet, and flows back to the first electrolyte tank through the first inlet and outlet, thus milling the workpiece.

[0017] The electrolysis method of the present invention enables electrolytic milling without replacing the electrolytic tube electrode after electrolytic drilling, while improving product removal efficiency and reducing stray corrosion zone on the workpiece surface during both electrolytic drilling and electrolytic milling.

[0031] Example 1

[0032] The electrolytic tube electrode proposed in this embodiment, such as Figure 1 and Figure 2As shown, the device includes an inner tube 1 and an outer tube 2. In this embodiment, the wall thickness of the inner tube 1 is preferably 0.1-0.5 mm, and the inner diameter is 0.3-0.8 mm; the wall thickness of the outer tube 2 is preferably 0.1-0.5 mm, and the inner diameter is 0.6-2 mm. The inner tube 1 is preferably a hollow tube, and it is provided with a first liquid inlet / outlet 101. The first liquid inlet / outlet 101 is a square hole located at the end of the inner tube 1, and multiple inlets / outlets are provided along the circumference of the inner tube 1. By providing multiple first liquid inlets / outlets 101, the product removal efficiency can be further improved, and the electrolytic milling efficiency can also be improved. The inner tube 1 has a second inlet / outlet 102 on its end face, that is, a second inlet / outlet 102 is provided at the bottom. The second inlet / outlet 102 is preferably located at the center of the inner tube 1. When the electrolyte enters from the center of the inner tube 1, it can diffuse more evenly to both ends of the tube electrode, ensuring that the entire electrode surface is wetted by the electrolyte, thereby improving the utilization rate of the electrolyte and the reactivity of the electrode. If the electrolyte enters from one end of the tube electrode, it may cause insufficient wetting in the central area of ​​the electrode, forming a wetting dead zone. Entering from the center helps to reduce such dead zones, ensuring that the electrolyte can reach every corner of the electrode. The first inlet / outlet 101 is connected to the second inlet / outlet 102. The outer tube 2 is sleeved outside the inner tube 1 and connected to the inner tube 1. A third inlet / outlet 201 is provided between the inner tube 1 and the outer tube 2. The third inlet / outlet 201 is a circular hole formed between the outer wall of the outer tube 2 and the inner tube 1. This design can further improve product removal efficiency and electrolytic milling efficiency. A fourth inlet / outlet 202 is provided on the side wall of the outer tube 2. The fourth inlet / outlet 202 is a square hole located at the end of the outer tube 2, preferably 1-5 mm from the end, and is located at the same end as the second inlet / outlet 102. The proximity of the fourth and second inlets / outlets allows for timely discharge of electrolyte and facilitates direct milling after drilling. Multiple inlets / outlets can also be evenly distributed along the axial direction, selected according to the actual machining depth. Multiple fourth inlets / outlets 202 are provided along the circumference of the outer tube 2, preferably 1-10. By providing multiple fourth inlets / outlets 202, product removal efficiency is further improved, and electrolytic milling efficiency is also enhanced. The opening angle of the fourth inlet / outlet 202 is 10-30 degrees, and the third inlet / outlet 201 communicates with the fourth inlet / outlet 202.

[0033] The working principle of an electrolytic tube electrode in this embodiment is as follows:

[0034] During electrolysis, the electrolyte tank is connected to the first inlet / outlet 101 and the third inlet / outlet 201, respectively, with the end face of the second inlet / outlet 102 facing the workpiece. For example... Figure 1 and Figure 2As shown, during drilling, the electrolyte enters the inner tube 1 through the first inlet / outlet 101, is sprayed onto the workpiece through the second inlet / outlet 102, and the electrolyzed electrolyte is drawn back into the outer tube 2 through the fourth inlet / outlet 202, and discharged from the outer tube 2 through the third inlet / outlet 201. This improves product removal efficiency and reduces stray corrosion zones on the workpiece surface during electrolytic drilling. After drilling is completed, milling operations can be performed using the electrodes of this electrolytic tube. Figure 1 and Figure 3 As shown, during milling, the electrolyte enters the outer tube 2 through the third inlet / outlet 201 and is sprayed onto the workpiece through the fourth inlet / outlet 202. The electrolyte, after electrolysis, is drawn back into the inner tube 1 through the second inlet / outlet 102 and discharged from the inner tube 1 through the first inlet / outlet 101. This improves product removal efficiency and reduces stray corrosion zones on the workpiece surface during electrolytic milling. By using a double-layer tube, electrolytic milling can be performed directly after electrolytic drilling, simplifying operation. When the electrolyte flows from the inner tube 1 to the electrode and then to the workpiece, it is discharged from the workpiece through the outer tube 2; conversely, when the electrolyte flows from the outer tube 2 to the electrode and then to the workpiece, it is discharged from the workpiece through the inner tube 1. This improves product removal efficiency and reduces stray corrosion zones on the workpiece surface during both electrolytic drilling and electrolytic milling.

[0035] Example 2

[0036] This embodiment proposes an electrolysis device, such as... Figure 4As shown, the assembly includes a mounting platform 3, a vertical moving mechanism 4, a first electrolyte tank 5, a first liquid pump 6, a second liquid pump 7, a power supply 8, a horizontal moving mechanism 9, a fixture 11, and the electrolytic tube electrode provided in Embodiment 1. The mounting platform 3 is connected to the output end of the horizontal moving mechanism 9. The horizontal moving mechanism 9 includes an X-axis moving mechanism and a Y-axis moving mechanism, both of which use commercially available linear motors or linear guides. The mounting platform 3 is connected to the output end of the horizontal moving mechanism 9. By setting up the horizontal moving mechanism 9, the mounting platform 3 can move horizontally and along the X and Y axes, thus enabling direct electrolytic milling after electrolytic drilling. The clamp 11 is connected to the output end of the vertical moving mechanism 4. In this embodiment, the vertical moving mechanism 4 can be a commercially available hydraulic press, linear motor, or multi-stroke cylinder. The electrolytic tube electrode is connected to the clamp 11. The first electrolyte tank 5 is connected to the first inlet / outlet 101 through the first liquid pump 6. The first electrolyte tank 5 is connected to the third inlet / outlet 201 through the second liquid pump 7. In this embodiment, it includes a first connecting pipe and a second connecting pipe. The two ends of the first connecting pipe are respectively connected to the first electrolyte tank 5 and the inner tube 1, and the two ends of the second connecting pipe are respectively connected to the first electrolyte tank 5 and the outer tube 2. The first liquid pump 6 is installed and connected to the first connecting pipe, and the second liquid pump 7 is installed and connected to the second connecting pipe. In this embodiment, the first liquid pump 6 and the second liquid pump 7 can draw liquid from the electrolyte tank to the electrolytic tube electrode, or draw liquid from the electrolytic tube electrode to the electrolyte tank. The first electrolyte tank 5 is filled with electrolyte, and the electrolyte flows to the surface of the workpiece through the electrolytic tube electrode. The negative terminal of the power supply 8 is electrically connected to the electrolytic tube electrode, and the positive terminal is electrically connected to the workpiece.

[0037] The workpiece is placed on the mounting platform 3, which is equipped with a clamping assembly to securely hold the workpiece. The vertical moving mechanism 4, the horizontal moving mechanism 9, the first liquid pump 6, the second liquid pump 7, and the power supply 8 are activated to bring the tube electrode close to the workpiece. During drilling, the liquid in the first electrolyte tank 5 is drawn by the first liquid pump 6 and enters the inner tube 1 through the first inlet / outlet 101. It is then sprayed onto the workpiece from the second inlet / outlet 102 to perform electrolytic drilling. At the same time, the second liquid pump 7 draws the electrolyte from the workpiece into the outer tube 2 through the fourth inlet / outlet 202, and then flows back to the first electrolyte tank 5 through the third inlet / outlet 201. This improves the efficiency of product removal during drilling and reduces the stray corrosion zone on the workpiece surface. During milling, the liquid in the first electrolyte tank 5 is drawn by the second liquid pump 7, enters the outer tube 2 through the third inlet / outlet 201, and is sprayed onto the workpiece through the fourth inlet / outlet 202 to perform electrolytic milling. Simultaneously, the first liquid pump 6 draws the electrolyte on the workpiece into the inner tube 1 through the second inlet / outlet 102, and flows back to the first electrolyte tank 5 through the first inlet / outlet 101. This improves the efficiency of product removal during milling and reduces stray corrosion zones on the workpiece surface. Furthermore, electrolytic milling can be performed directly after electrolytic drilling, simplifying the operation.

[0038] It also includes a rotary motor 10, which is connected to the output end of the vertical moving mechanism 4. The clamp 11 is connected to the output end of the rotary motor 10, and the electrolytic tube electrode is rotatably connected to the clamp 11. By setting the rotary motor 10, the electrolytic tube electrode is driven to rotate, thereby making the electrolyte spray more uniform and improving the product removal efficiency, thereby further reducing the stray corrosion zone on the workpiece surface.

[0039] The device also includes a filtration mechanism 14 and a second electrolyte tank 15, which are connected via the filtration mechanism 14. During drilling, the first electrolyte tank 5 is connected to the first inlet / outlet 101 via a first liquid pump 6, and the second electrolyte tank 15 is connected to the third inlet / outlet 201 via a second liquid pump 7. During milling, the first electrolyte tank 5 is connected to the third inlet / outlet 201 via the second liquid pump 7, and the second electrolyte tank 15 is connected to the first inlet / outlet 101 via the first liquid pump 6. By setting up the second electrolyte tank 15, new electrolyte is separated from the used electrolyte, preventing contamination that could affect electrolysis efficiency. Simultaneously, by setting up the filtration mechanism 14, the used electrolyte is filtered before flowing back into the electrolyte tank for use, allowing the electrolyte in the device to be recycled.

[0040] like Figure 5As shown, the fixture 11 has a first inlet / outlet 111 and a second inlet / outlet 112. A partition 12 is provided inside the fixture 11, and the electrolytic tube electrode is rotatably connected to the partition 12. The partition 12 divides the interior of the fixture 11 into a first connecting portion 113 and a second connecting portion 114. During drilling, the first inlet / outlet 101, the first connecting portion 113, the first inlet / outlet 111, the first liquid pump 6, and the first electrolyte tank 5 are connected sequentially; the third inlet / outlet 201, the second connecting portion 114, the second inlet / outlet 112, the second liquid pump 7, and the second electrolyte tank 15 are connected sequentially. During milling, the first inlet / outlet 101, the first connecting portion 113, the first inlet / outlet 111, the first liquid pump 6, and the second electrolyte tank 15 are connected sequentially; the third inlet / outlet 201, the second connecting portion 114, the second inlet / outlet 112, the second liquid pump 7, and the first electrolyte tank 5 are connected sequentially. The fixture 11 allows the electrolytic tube electrode to connect with the first electrolyte tank 5 while rotating. It also includes a sealed bearing 13, through which the electrolytic tube electrode and the clamp 11 are rotatably connected, and through the sealed bearing 13, the electrolytic tube electrode and the partition 12 are rotatably connected. The clamp 11 is sealed by the sealed bearing 13, thereby preventing the electrolyte from being sucked back before it is sprayed onto the workpiece.

Drilling is performed on the workpiece; the vertical moving mechanism 4 is closed, and the horizontal moving mechanism 9 is started to move the workpiece horizontally. The first liquid pump 6 and the second liquid pump 7 are started in reverse. The electrolyte in the first electrolyte tank 5 enters the electrolytic tube electrode through the third inlet / outlet 201 and is sprayed onto the workpiece through the fourth inlet / outlet 202. The electrolyte on the workpiece enters the electrolytic tube electrode through the second inlet / outlet 102 and flows back to the first electrolyte tank 5 through the first inlet / outlet 101. The workpiece is then milled. After the machining is completed, the horizontal moving mechanism 9 is closed, the vertical moving mechanism 4 is started to move the electrolytic tube electrode away from the workpiece, the electrolysis device is turned off, and the workpiece is removed.
