Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic machining, and more specifically, to an electrolytic tube electrode, an electrolytic device and an electrolytic method. Background Art

[0002] Tube electrode electrochemical machining is a machining method that uses a hollow tube as a cathode to electrochemically dissolve the workpiece anode. Usually, the electrolyte sprays out from the bottom end of the tube electrode, collides with the processed bottom surface, and then reflects to the gap between the tube electrode and the workpiece, thereby dissolving the workpiece anode. When electrolytic milling is required for the middle of the workpiece, it is necessary to use a punching tube electrode to drill a hole in the workpiece, and then replace the milling tube electrode to perform milling on the workpiece, which is cumbersome.

[0003] At the same time, during the processing, Joule heat and the difficulty of discharging electrolytic products will appear. The electrolyte is easy to accumulate on the surface of the workpiece, causing serious stray corrosion, which in turn affects the processing efficiency and quality. Especially as the aspect ratio continues to increase, the pressure of the electrolyte along the process continues to increase, the flow rate drops rapidly, and the electrolytic products are more likely to accumulate, eventually causing sparks or even short circuits, seriously reducing the processing stability and processing quality. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art in which electrolytic milling of the middle part of a workpiece is complicated and the efficiency of removing electrolytic products is low, resulting in stray corrosion. An electrolytic tube electrode, an electrolytic device and an electrolytic method are provided to facilitate electrolytic milling of the middle part of a workpiece, while improving the efficiency of removing electrolytic products and reducing the stray corrosion area on the workpiece surface.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The electrolysis tube electrode of the present invention, during electrolysis, connects the electrolyte box to the first inlet and outlet and the third inlet and outlet, respectively, and faces the end face of the second inlet and outlet toward the workpiece. During drilling, the electrolyte enters the inner tube from the first inlet and outlet, sprays toward the workpiece from the second inlet and outlet, sucks the electrolyte completed by electrolysis back into the outer tube through the fourth inlet and outlet, and discharges from the outer tube through the third inlet and outlet, which can improve the product removal efficiency during electrolytic drilling and reduce the stray corrosion area on the workpiece surface.

When the electrolyte enters the tube electrode from the inner tube and flows to the workpiece, the electrolyte on the workpiece is discharged through the outer tube; when the electrolyte enters the tube electrode from the outer tube and flows to the workpiece, the electrolyte on the workpiece is discharged through the inner tube; the product removal efficiency can be improved during electrolytic drilling and electrolytic milling, and the stray corrosion area on the workpiece surface can be reduced.

The inner tube 1 is preferably a hollow tube, and the inner tube 1 is provided with a first liquid inlet and outlet 101. The first liquid inlet and outlet 101 is set as a square hole, located at the end of the inner tube 1, and multiple liquid inlet and outlet 101 are provided along the circumference of the inner tube 1.

The inner tube 1 has a second liquid inlet and outlet 102 at its end face, that is, the bottom has a second liquid inlet and outlet 102. The second liquid inlet and outlet 102 is preferably opened at the center of the inner tube 1. When the electrolyte enters from the middle of the inner tube 1, it can be more evenly diffused to both ends of the tube electrode to ensure that the entire electrode surface is infiltrated by the electrolyte, thereby improving the utilization rate of the electrolyte and the reaction activity of the electrode. If the electrolyte enters from one end of the tube electrode, it may cause insufficient infiltration of the central area of ​​the electrode, forming an infiltration dead angle. Entering from the middle helps to reduce this dead angle and ensure that the electrolyte can reach every corner of the electrode. The first liquid inlet and outlet 101 is connected to the second liquid inlet and outlet 102, the outer tube 2 is sleeved outside the inner tube 1, the outer tube 2 is connected to the inner tube 1, and there is a third liquid inlet and outlet 201 between the inner tube 1 and the outer tube 2. The third liquid inlet and outlet 201 is set as a circular hole, and the circular hole is formed between the outer tube 2 and the outer wall of the inner tube 1. It can further improve the product removal efficiency, and also improve the electrolytic milling efficiency. The side wall of the outer tube 2 is provided with a fourth liquid inlet and outlet 202, and the fourth liquid inlet and outlet 202 is set as a square hole, located at the end of the outer tube 2, preferably 1-5mm away from the end, and located at the same end as the second liquid inlet and outlet 102. The fourth liquid inlet and outlet are close to the second liquid inlet and outlet, so that the electrolyte can be discharged in time, and it is convenient to directly perform milling after drilling. It can also be evenly distributed along the axial direction, and selected according to the actual situation of the processing depth. The fourth liquid inlet and outlet 202 is provided with multiple, preferably 1-10, along the circumference of the outer tube 2. By setting multiple fourth liquid inlet and outlet 202, the product removal efficiency is further improved, and the electrolytic milling efficiency can also be improved. The fourth liquid inlet and outlet 202 is opened at an angle of 10-30 degrees, and the third liquid inlet and outlet 201 is connected to the fourth liquid inlet and outlet 202.

[0035] The working principle of an electrolysis tube electrode in this embodiment is as follows:

[0036] During electrolysis, the electrolyte tank is connected to the first liquid inlet and outlet 101 and the third liquid inlet and outlet 201 respectively, and the end face of the second liquid inlet and outlet 102 is facing the workpiece. Figure 1 and Figure 2As shown, when drilling, the electrolyte enters the inner tube 1 from the first inlet and outlet 101, sprays toward the workpiece from the second inlet and outlet 102, and sucks the electrolyte after electrolysis back into the outer tube 2 through the fourth inlet and outlet 202, and is discharged from the outer tube 2 through the third inlet and outlet 201, which can improve the product removal efficiency during electrolytic drilling and reduce the stray corrosion area on the workpiece surface. After drilling is completed, the electrolytic tube electrode can be used for milling operations. Figure 1 and Figure 3 As shown, during milling, the electrolyte enters the outer tube 2 from the third liquid inlet and outlet 201, sprays toward the workpiece from the fourth liquid inlet and outlet 202, sucks the electrolyte after electrolysis back into the inner tube 1 through the second liquid inlet and outlet 102, and discharges from the inner tube 1 through the first liquid inlet and outlet 101, which can improve the product removal efficiency during electrolytic milling and reduce the stray corrosion area on the workpiece surface. By setting up a double-layer tube, electrolytic milling can be performed directly after electrolytic drilling, which is easy to operate. When the electrolyte enters the tube electrode from the inner tube 1 and flows toward the workpiece, the electrolyte on the workpiece is discharged through the outer tube 2; when the electrolyte enters the tube electrode from the outer tube 2 and flows toward the workpiece, the electrolyte on the workpiece is discharged through the inner tube 1, which can improve the product removal efficiency during electrolytic drilling and electrolytic milling and reduce the stray corrosion area on the workpiece surface.
