Description

Technical Field

[0001] The present invention relates to the field of electrolysis technology, and particularly to a jet electrolysis device for electrolyzing T-shaped workpieces. Background Art

[0002] In recent years, with the rapid development of science and technology, the sizes of parts tend to be miniaturized and precision-oriented, and microstructures have been widely applied in fields such as aerospace, electronic instruments, and biomedical devices. With the diverse development of materials, it is often necessary to machine microstructures on some difficult-to-machine materials with high strength and hardness, which poses a great challenge to traditional machining methods. For materials with high strength and hardness, traditional machining methods have many problems, including tool wear, insufficient tool hardness, and the presence of a heat-affected layer in the machining area, resulting in difficulty in achieving precise microstructural machining on the surfaces of high-strength and high-hardness materials.

[0003] Compared with traditional mechanical cutting machining, electrolytic machining technology, as a non-contact machining method, shows obvious advantages in the machining of microstructures. During the machining process, electrolytic machining technology does not need to rely on mechanical energy and can directly utilize electrical energy and electrochemical energy to precisely machine workpieces.

[0004] In the existing electrolytic machining technology, due to the failure to timely discharge the workpiece surface products generated during the electrolysis process, the surface roughness of the workpiece is relatively high. In addition, cylindrical nozzle-type jet electrolysis may cause the electrolyte to diffuse into areas outside the designated electrolysis area, resulting in secondary corrosion and an increase in the surface roughness of the workpiece. For complex structures such as T-shaped workpieces, due to the positional differences between the planes and chamfers of T-shaped workpieces, it is difficult for the existing technology to achieve efficient and uniform electrolysis of T-shaped workpieces. Summary of the Invention

[0006] The object of the present invention is mainly achieved through the following technical solutions:

[0007] In a first aspect, an embodiment of the present invention provides a jet electrolysis device for electrolyzing T-shaped workpieces, including: an electrolysis shell 3, an electrolyte inlet system, an electrolyte inner cavity system, a T-shaped workpiece groove 4, a sealing cover 2, and a slider connecting member 1. The surface of the electrolysis shell 3 is provided with a cathode wire interface 5 and an electrolyte inlet 6; on the inner walls of two opposite sides of the electrolysis shell 3, there are frustums 15;

[0016] The circulation pipeline 7 is hermetically connected to the electrolytic cell shell by spot welding; to ensure that after the electrolyte enters the circulation pipeline, it all flows out through the circulation pipeline outlet 10.

[0017] The electrolyte inner cavity system includes a distribution network 8 provided with a liquid inlet above the distribution network 11, a first liquid inlet on the surface of the distribution network 12, and a second liquid inlet on the surface of the distribution network 13; the distribution network 8 is arranged below the circulation pipeline 7, and the outer diameter size of the distribution network 8 is the same as the inner diameter size of the circulation pipeline 7.

[0018] The distribution network 8 is a cuboid cavity structure with one end open and the opening facing downwards. The upper liquid inlets 11 are evenly arranged on both sides of the upper surface of the distribution network 8. There is no liquid inlet design in the middle position of the upper surface of the distribution network 8, forming a strip-shaped area without liquid inlets perpendicular to the two side walls. The upper liquid inlets 11 are symmetrically distributed on both sides of this strip-shaped area;

[0019] The surface liquid inlets 12 and the surface liquid inlets 13 are arranged from top to bottom on the two long side faces of the distribution network 8.

[0020] Preferably, the diameter of the first liquid inlet on the surface of the uniform distribution net is 2 mm, and the diameter of the liquid inlet 13 of the T-shaped part structure is designed to be 1 mm. Through the buffering effect of the liquid inlet 11 above the uniform distribution net and the surface liquid inlets 12 and 13, the electrolyte enters the uniform distribution net evenly, thereby ensuring that the electrolyte is ejected from the jet slit 14 at a constant pressure flow rate, realizing uniform electrolysis of the T-shaped workpiece.

[0021] A slit structure 16 extending in the height direction is provided on the side surface of the segment of the uniform distribution net 8 for an interference fit with the frustum 15 of the electrolytic shell to ensure the stability and tightness of the structure.

[0022] The T-shaped workpiece groove 4 is provided with a conforming jet slit 14, and the jet slit 14 is T-shaped; the periphery of the flange of the T-shaped workpiece groove 4 is hermetically connected to the bottom side wall of the uniform distribution net 8, and the web of the T-shaped workpiece groove 4 is located inside the cuboid cavity of the uniform distribution net 8.

[0023] Specifically, the size of the jet slit is 0.8 - 1.2 mm, preferably 1 mm.

[0027] The guide rail includes a slider; the slider 17 is connected to the slider connecting member 1 of the electrolytic device, and the guide rail is controlled by a motor to rotate at a constant speed, thereby driving the overall electrolytic device to move at a constant speed, ensuring that the electrolyte can be evenly sprayed onto the entire surface of the T-shaped workpiece.

[0028] During the electrolysis process, the specific connection method is: the liquid outlet of the high-pressure plunger pump is connected to the liquid inlet 6 of the electrolytic device, and the liquid inlet pipeline of the high-pressure plunger pump is connected to the machining tank; the anode of the pulse power supply is connected to the T-shaped workpiece through a wire, and the cathode is connected to the electrolyte through the cathode wire interface 5.

[0029] In a third aspect, the present invention provides a jet electrolytic process for electrolyzing a T-shaped workpiece, and the specific steps include:

[0030] S1: Pretreat the surface of the T-shaped workpiece;

[0031] S2: Prepare the required electrolyte;

[0032] S3: Connect the liquid outlet of the high-pressure plunger pump to the electrolyte inlet 6 of the electrolytic cell 3. The electrolyte flows from the liquid outlet of the high-pressure plunger pump through the electrolyte inlet 6 into the circulation pipeline 7 of the electrolyte inlet system; then it flows through the distribution mesh 8 of the electrolyte inner cavity system, and then the electrolyte passes through the jet slit 14 of the T-shaped workpiece groove 4 and is uniformly sprayed onto the T-shaped workpiece.

[0033] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0034] 1. The present invention provides a jet electrolysis device for electrolyzing a T-shaped workpiece, including a T-shaped workpiece groove, an electrolyte inlet system, and an electrolyte inner cavity system; wherein the T-shaped workpiece groove includes a jet slit with a "T" shape. The electrolyte flows from the electrolyte inlet, successively through the electrolyte inlet system and the electrolyte inner cavity system, and finally is uniformly and highly speedily sprayed onto the T-shaped workpiece through the jet slit; the jet slit adopts a "T" shape structure, and this special-shaped nozzle can perform overall electrolysis on the T-shaped workpiece, realizing uniform and smooth electrolysis of each surface and chamfer of the T-shaped workpiece, and solving the problem of poor uniformity caused by staged electrolysis.

[0035] 2. The jet electrolysis device of the present invention is provided with a slider connecting member, and the slider connecting member can be detachably connected to the slider on the guide rail; the uniform rotation of the guide rail drives the slider to move, thereby driving the electrolysis device to move uniformly on the surface of the T-shaped workpiece, realizing uniform and smooth electrolysis of the T-shaped workpiece, and avoiding the problem of large surface roughness of the workpiece caused by uneven spraying of the electrolyte.

[0036] 3. The jet nozzle designed by the present invention adopts a "T" shape structure. By arranging the jet slit inside the T-shaped workpiece groove and setting the jet slit to conform to the shape of the T-shaped workpiece groove, it is arranged along the horizontal direction, vertical direction, and horizontal direction of the T-shaped workpiece groove, extending to the inside and top of the T-shaped workpiece groove to form a "T"-shaped jet slit. This shape of the jet slit enables the electrolyte to be sprayed onto each surface and chamfer of the T-shaped workpiece, and can process special angles and positions that are difficult to process by other electrolysis processes, having good accessibility, and realizing efficient and uniform electrolysis of the T-shaped workpiece.

[0037] 4. In the present invention, under the action of the pressure pump, the electrolyte passes through the jet slit type nozzle, that is, the "T"-shaped jet slit, and is highly speedily sprayed onto the T-shaped workpiece. The highly speedily sprayed electrolyte will timely wash away the surface products generated during the electrolysis process on the workpiece surface, reducing the surface roughness of the workpiece after electrolysis.

[0038] 5. During the jet electrolysis process of the present invention, the anode of the pulsed power supply is connected to the T-shaped workpiece through a wire, and the cathode is connected to the electrolyte through the cathode wire interface of the electrolysis device; there is no need to design a formed cathode, eliminating the traditional cathode plate structure, thereby avoiding the wear and loss of the cathode workpiece during the electrolysis process and reducing the processing cost.

[0039] 6. The present invention provides a liquid inlet for the circulation pipeline on the opposite side walls of the circulation pipeline, and a liquid outlet for the circulation pipeline on the upper surface of the circulation pipeline; and the uniform distribution network is provided with an upper liquid inlet, a first surface liquid inlet of the uniform distribution network, and a second surface liquid inlet of the uniform distribution network; the outer diameter dimension between the two side walls of the uniform distribution network is the same as the inner diameter dimension between the two side walls of the circulation pipeline, and the outer diameter dimension between the front and back surfaces of the uniform distribution network is smaller than the inner diameter dimension between the front and back surfaces of the circulation pipeline.

[0040] This structural and dimensional design of the circulation pipeline and the uniform distribution network can ensure that the electrolyte enters the circulation cavity of the circulation pipeline through the liquid inlet of the circulation pipeline. After the electrolyte is mixed evenly in the circulation pipeline and flows out through the liquid outlet holes of the circulation pipeline, it flows into the uniform distribution network through the upper liquid inlet of the uniform distribution network with the same pressure and flow rate. The first surface liquid inlet and the second surface liquid inlet can enable the electrolyte to flow back into the uniform distribution network for the second time. Through the buffering effect of the upper liquid inlet, the first surface liquid inlet and the second surface liquid inlet of the uniform distribution network, the electrolyte enters the uniform distribution network evenly, thereby ensuring that the electrolyte is fully mixed in the device and ensuring the uniformity of the electrolyte.

[0041] 7. The present invention adopts the jet electrolysis process. The electrochemical dissolution behavior of the workpiece material only depends on its own electrochemical properties, and the mechanical properties of the material such as hardness and ductility have no influence on the processing process. Therefore, the jet electrolysis technology of the present invention can be used to process materials that are difficult to process by traditional cutting processing technologies such as superalloys, hardened steels, and titanium alloys, and the applicable range of metal materials is wider.

[0042] 8. During the processing of the jet electrolysis system provided by the present invention, the reduction of the metal material is in units of tiny ions. The surface finish of the processed workpiece is good and the roughness is small; there is no thermal stress or mechanical stress during the processing, and there is no residual stress on the surface of the workpiece after processing, and there is no burr, so thin-walled parts can be machined; there is no workpiece loss during the processing, and the service life is long.

[0043] 9. Install the electrolysis device on the guide rail slider, fix the T-shaped workpiece 0.5 mm below the jet slit of the electrolysis device, adjust the pressure of the high-pressure piston pump to 5 - 10 MPa, and electrolyze for 30 minutes when the current is 8 - 10 A. The overall electrolysis of each plane and chamfer of the T-shaped workpiece is achieved. The roughness of the chamfer and plane of the T-shaped workpiece is controlled within 2.33 - 2.56 μm. Therefore, the jet electrolysis process of the present invention achieves an efficient and uniform electrolysis effect on the T-shaped workpiece.

[0044] In the present invention, the above technical solutions can also be combined with each other to achieve more preferred combined solutions. Other features and advantages of the present invention will be described in the subsequent description, and some advantages can be made obvious from the description, or understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained from the content specifically pointed out in the description and the drawings. Description of the Drawings

[0055] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, rather than to limit the scope of the present invention.

[0056] The T-shaped workpiece structure includes a horizontal plane, a vertical plane, and a chamfer formed by the horizontal plane and the vertical plane. Due to the complexity of its structure, it is difficult for the existing electrolysis process to electrolyze the T-shaped workpiece as a whole, and it is difficult to achieve an efficient and uniform electrolysis effect. When electrolyzing each surface and chamfer of the T-shaped workpiece in stages, it will lead to uneven electrolysis. At the same time, during the electrolysis process, if the reaction products on the surface of the workpiece cannot be discharged in time, the generated debris is likely to deposit on the surface of the workpiece, causing secondary corrosion, and then resulting in problems such as uneven surface, burrs, large roughness, and non-smoothness of the workpiece surface. It is found in the research that cylindrical nozzle jet electrolysis may cause the electrolyte to diffuse to areas outside the designated electrolysis area, resulting in secondary corrosion and an increase in the surface roughness of the workpiece. Therefore, developing a device that can be used for the overall smooth and uniform electrolysis of T-shaped workpieces is of great significance for the electrolysis of T-shaped workpieces.

[0057] The present invention provides a jet electrolysis device for electrolyzing a T-shaped workpiece, including an electrolysis shell 3, an electrolyte inlet system, an electrolyte inner cavity system, a sealing cover 2, a slider connecting member 1, and a T-shaped workpiece groove 4.

[0058] The electrolysis shell 3 encloses a cavity with openings at both the upper and lower ends. The sealing cover 2 is hermetically connected to the upper end of the cavity, and the slider connecting member 1 is fixedly connected to the upper end surface of the sealing cover 2. The electrolyte inlet system and the electrolyte inner cavity system are arranged in the cavity from top to bottom. The main body of the T-shaped workpiece groove 4 is located in the inner cavity of the electrolyte inner cavity system.

[0059] Among them, the electrolysis shell 3 is used to accommodate the electrolyte inlet system, the electrolyte inner cavity system, and the T-shaped workpiece groove. The sealing cover 2 is used to seal the upper end of the electrolysis device. The slider connecting member 1 is used for connecting the slider on the guide rail, and the electrolysis device is moved by the rotation of the guide rail. The T-shaped workpiece groove 4 is used to match the T-shaped workpiece. The electrolyte inlet system is used to provide electrolyte into the cavity. The electrolyte inner cavity system is used to ensure that after the electrolyte is fully mixed, it flows into the injection port at a uniform speed and then is evenly sprayed onto the T-shaped workpiece.

[0060] Furthermore, the electrolysis shell 3 is made of stainless steel material, having strong corrosion resistance, high pressure resistance, high temperature resistance and other stabilities, and a long service life.

[0061] The electrolytic cell housing 3 includes a cathode wire interface 5, an electrolyte inlet 6, and a frustum 15. The cathode wire interface 5 is used to connect the cathode wire of the pulsed power supply. The electrolyte inlet 6 is used for the electrolyte to flow from the electrolyte container into the electrolyte inlet system of the jet electrolysis device. The frustum 15 is used to form an interference fit with the electrolyte inner cavity system, thereby fixing the electrolyte inner cavity system in the cavity of the electrolytic cell housing.

[0062] Specifically, on the left and right sides of the electrolytic cell housing, electrolyte inlets 6 are provided. The electrolyte flows into the electrolyte inlet system simultaneously and uniformly through the electrolyte inlets on the left and right sides, ensuring the uniformity of the electrolyte in the circulation pipeline.

[0063] As Figure 3 shown, the electrolyte inlet system includes a circulation pipeline 7 provided with a circulation pipeline inlet 9 and a circulation pipeline outlet 10. The circulation pipeline 7 is formed by connecting four square pipelines end to end, and the cross-section of the enclosed area in the middle is rectangular. The circulation pipeline 7 is made of stainless steel material, having the advantages of corrosion resistance, high pressure resistance, high temperature resistance, and long service life.

[0064] Specifically, a plurality of circulation pipeline outlet holes 10 communicating with the circulation cavity of the circulation pipeline 7 are provided on the upper surface of the circulation pipeline 7, ensuring that after the electrolyte enters the circulation cavity of the circulation pipeline, it uniformly flows into the electrolyte inner cavity system through the electrolyte outlet holes, and realizing the recycling of the electrolyte, reducing the processing cost.

[0065] Furthermore, circulation pipeline inlets 9 communicating with the circulation cavity of the circulation pipeline 7 are provided on the opposite side walls of the circulation pipeline 7; furthermore, the diameter of the circulation pipeline inlet 9 is consistent with the diameter of the electrolyte inlet 6. The circulation pipeline 7 is hermetically connected to the four sides of the electrolytic cell housing 3 by spot welding, so that the circulation pipeline inlet 9 is closely attached to the electrolyte inlet 6, ensuring that the electrolyte smoothly enters the circulation pipeline through the electrolyte inlet 6 and the circulation pipeline inlet 9; the spot welding method can solve the problem of easy deformation in overall welding.

[0066] As Figure 4 shown, the electrolyte inner cavity system includes a distribution mesh 8 provided with a liquid inlet above the evenly distributed mesh 11, a liquid inlet on the surface of the first evenly distributed mesh, and a liquid inlet on the surface of the second evenly distributed mesh, ensuring that the electrolyte is ejected from the jet slit 14 at a constant pressure flow rate to achieve the expected experimental effect and reduce experimental errors. The distribution mesh 8 is made of stainless steel material.

[0067] Specifically, the distribution mesh 8 is in the shape of a cuboid with one end open and the opening facing downwards, and the internal structure is a cavity structure, which is used to accommodate the electrolyte and mix the electrolyte evenly; the distribution mesh 8 is made of stainless steel material, having the advantages of corrosion resistance, high pressure resistance, high temperature resistance, and long service life.

[0068] The upper surface of the uniform distribution network 8 is provided with an upper liquid inlet 11, and the front and back surfaces of the uniform distribution network 8, that is, the two long side surfaces, are both provided with a surface liquid inlet 12 and a surface liquid inlet 13.

[0069] Specifically, the upper liquid inlets 11 are uniformly arranged on both sides of the upper surface, with no liquid inlet design in the middle, forming a straight line perpendicular to the two side walls without liquid inlets. The upper liquid inlets 11 are symmetrically distributed on both sides of this straight line. The upper liquid inlets 11 on both sides are arranged in an array along the length direction. This design is to ensure that after the electrolyte flows out from the liquid outlet 10 of the circulation pipeline, it enters the uniform distribution network with the same pressure and flow rate, avoiding the pressure difference and different flow rates caused by setting liquid inlets in the middle and on both sides at the same time.

[0070] The first surface liquid inlet 12 of the uniform distribution network and the second surface liquid inlet 13 of the uniform distribution network are arranged from top to bottom on the front and back surfaces of the uniform distribution network 8, that is, the two long side surfaces. Preferably, the diameter of the first surface liquid inlet of the uniform distribution network is 2 mm, which can reduce the inlet resistance and enable the overflowing electrolyte to enter the uniform distribution network structure evenly and quickly. In cooperation with the T-shaped part structure, the diameter of the liquid inlet 13 is designed to be 1 mm. By restricting the flow rate and balancing the flow rates of each path, the electrolyte is prevented from flowing unevenly, and all the electrolyte enters the uniform distribution network structure.

[0071] Through the buffering effect of the upper liquid inlet 11, the first surface liquid inlet 12, and the second surface liquid inlet 13 of the uniform distribution network, the electrolyte enters the uniform distribution network evenly, and then ensures that the electrolyte is ejected from the jet slit 14 at a constant pressure and flow rate, realizing the uniform electrolysis of the T-shaped workpiece.

[0072] The uniform distribution network 8 is arranged below the circulation pipeline 7. The outer diameter size of the uniform distribution network 8 is the same as the inner diameter size of the circulation pipeline 7. That is to say, the vertical projection area of the uniform distribution network 8 is included in the vertical projection area of the circulation pipeline 7, and the outer contour projection line of the uniform distribution network 8 coincides with the inner contour projection line of the circulation pipeline. The outer diameter size between the two side walls of the uniform distribution network 8 is the same as the inner diameter size between the two side walls of the circulation pipeline 7, and the uniform distribution network is in contact with the circulation pipeline, which is convenient for the electrolyte to flow out from the liquid outlet 10 on the upper surface of the circulation pipeline 7 and then flow into the uniform distribution network from the middle rectangular area; the outer diameter size between the front and back surfaces of the uniform distribution network 8 is smaller than the inner diameter size between the front and back surfaces of the circulation pipeline 7, so that the electrolyte flows back twice through the first surface liquid inlet 12 and the second surface liquid inlet 13 of the uniform distribution network and evenly flows into the interior of the uniform distribution network, ensuring that the electrolyte is fully mixed in the uniform distribution network and ensuring that after the electrolyte flows through the jet slit, it is evenly sprayed onto the T-shaped workpiece.

[0073] Furthermore, gap structures 16 are provided on the opposite two side walls of the uniform distribution network 8, that is, the short side sides, for an interference fit with the frustum 15 of the electrolysis shell, ensuring the stability and sealing performance of the structure connecting the uniform distribution network 8 and the electrolysis shell.

[0074] The main body of the T-shaped workpiece slot 4 is located in the inner cavity of the electrolyte inner cavity system, and the lower end of the main body of the T-shaped workpiece slot 4 is sealed and connected to the lower end of the cavity with two ends opened and surrounded by the electrolysis shell 3. The flange of the T-shaped workpiece slot 4 is sealed and connected to the bottom side wall of the uniformly distributed net 8, and the web of the T-shaped workpiece slot 4 is located in the rectangular cavity of the uniformly distributed net 8.

[0075] The T-shaped workpiece groove 4 is provided with a conformal jet slit 14, and the jet slit 14 is T-shaped; the jet slit of this shape enables the electrolyte to be sprayed onto various surfaces and chamfers of the T-shaped workpiece, and has good accessibility.

[0076] Preferably, the jet slit size is 0.8-1.2mm, such as 0.9mm, 1.0mm, 1.1mm, preferably 1mm; the jet slit is a "T"-shaped nozzle. By designing this special shape of nozzle, special angles and positions that are difficult to process by other processing methods can be processed. It has good accessibility and can achieve efficient processing of T-shaped workpieces.

[0077] In the specific assembly process, in the electrolytic device, the uniformly distributed mesh is placed at the prism to form an interference fit with the electrolytic device, the circulating pipeline is welded to the inner shell of the electrolytic device by spot welding, the top of the electrolytic device is connected to the sealing cover by bolts, and the slider connector is fixedly connected to the top of the sealing cover by bolts.

[0078] During the electrolysis process, the electrolysis device is mounted on the guide rail slider, and the T-shaped workpiece is fixed in the T-shaped workpiece slot of the electrolysis device, and the distance between the T-shaped workpiece slot and the workpiece slot is maintained at 0.5 mm. The anode of the pulse power supply is connected to the T-shaped workpiece through a wire, and the cathode is connected to the electrolyte through the cathode wire interface 5 of the electrolysis device. After starting the power supply, the electrolyte enters the circulation pipeline 7 through the electrolyte inlet 6, and then flows out from the circulation pipeline outlet 10, and flows into the uniformly distributed net through the upper inlet 11 of the uniformly distributed net. The overflowed electrolyte flows into the uniformly distributed net through the first uniformly distributed net surface inlet 12 and the second uniformly distributed net surface inlet 13; after being mixed in the uniformly distributed net, it flows into the T-shaped workpiece slot 4 at a uniform speed, and finally sprays to the T-shaped workpiece through the jet slit 14.

[0079] The jet shape of the jet slit in the jet electrolysis device of this embodiment is the same as that of the T-shaped workpiece, ensuring that the electrolyte can be evenly distributed throughout the workpiece surface, and the high-speed flowing electrolyte acts as a cathode, so there is no need to design a cathode plate, avoiding wear and loss of the cathode workpiece.

[0080] The present invention also provides a jet electrochemical machining system for electrochemically machining a T-shaped workpiece, specifically including: the above-mentioned jet electrochemical machining device, a high-pressure plunger pump, a machining tank, a guide rail, a power supply, and a motor. The high-pressure plunger pump is used to provide pressure and electrolyte. The machining tank is used to fix the T-shaped workpiece and hold the electrolyte after electrolysis. The guide rail drives the slider to move through rotation, and then drives the uniform movement of the jet electrochemical machining device. The anode of the power supply is connected to the T-shaped workpiece, and the cathode is connected to the electrolyte through the cathode wire interface 5 of the electrochemical machining device to realize the electrochemical machining process. The motor is used to control the movement of the guide rail.

[0081] Further, the high-pressure plunger pump includes a pressure pump 22 and an electrolyte storage tank 23. The pressure pump 22 is located above the electrolyte storage tank 23 and is fixedly connected to the electrolyte storage tank 23, ensuring that the electrolyte smoothly passes through the electrolyte inlet 6, successively through the circulation pipeline 7, the distribution network 8, and finally is uniformly sprayed onto the T-shaped workpiece through the jet slit 14 under the action of pressure. At the same time, the pressure provided by the pressure pump enables the electrolyte to have a relatively high flow rate, which can smoothly discharge the debris generated during the electrolysis process from the surface and chamfer of the T-shaped workpiece.

[0082] The electrolyte storage tank 23 is located below the pressure pump 22 and supplies the electrolyte to the jet electrochemical machining device under the action of pressure. After the electrolyte is sprayed onto the T-shaped workpiece through the jet slit 14 of the jet electrochemical machining device to complete the electrolysis process, it further flows into the electrolyte storage tank through the inlet pipeline of the high-pressure plunger pump, realizing the recycling of the electrolyte and reducing the processing cost.

[0083] The machining tank 21 includes an electrolyte container for holding the electrolyte that has been sprayed out from the jet slit 14 of the jet electrochemical machining device and has completed electrolysis. The machining tank may also include a support frame placed inside the electrolyte container for supporting the T-shaped workpiece.

[0084] The guide rail includes a slider, and the slider is detachably connected to the slider connecting member 1 of the jet electrochemical machining device; the guide rail is fixed on the guide rail frame, and the motor controls the guide rail to rotate uniformly to drive the slider to move, thereby driving the entire electrochemical machining device to move uniformly on the T-shaped workpiece, ensuring that the electrolyte is uniformly sprayed onto the workpiece surface to make the electrolysis more uniform and smooth.

[0085] The specific connection method is as follows: the anode wire of the pulse power supply is connected to the T-shaped workpiece, and the cathode wire of the pulse power supply is connected to the electrolyte through the cathode wire interface 5; the inlet pipeline of the high-pressure plunger pump is connected to the processing tank, and the electrolyte inlet 6 is connected to the outlet of the high-pressure plunger pump through a pipeline. The electrolyte flows from the outlet of the high-pressure plunger pump into the circulation pipeline 7 through the electrolyte inlet 6. After being mixed evenly in the circulation pipeline 7, it flows out through the outlet of the circulation pipeline 10. Subsequently, after being buffered and mixed evenly by the distribution network, the electrolyte is evenly sprayed onto the T-shaped workpiece through the jet slit 14. The electrolyte that has completed electrolysis flows into the processing tank and finally enters the electrolyte storage tank through the inlet pipeline of the high-pressure plunger pump, realizing the recycling of the electrolyte.

[0086] During the electrolysis process, under the driving force of the motor, the guide rail is controlled to rotate uniformly to drive the slider to move, thereby driving the entire electrolysis device to move uniformly on the T-shaped workpiece. Under the action of the pressure pump, the electrolyte flows into the circulation pipeline uniformly at the same flow rate. Subsequently, through the buffering action of the distribution network, it is evenly sprayed onto the T-shaped workpiece to ensure smooth and uniform electrolysis of the workpiece.

[0087] The present invention also provides a jet electrolysis method for a T-shaped workpiece, including the following steps:

[0088] S1: Pretreat the surface of the T-shaped workpiece. First, use an alcohol solution to deeply clean the workpiece to remove metal oxide impurities on the surface of the workpiece, and then use deionized water to clean the workpiece. After drying, it is ready for use.

[0089] S2: Configure the required electrolyte: The electrolyte composition is a saturated sodium chloride NaCl and potassium bromide KBr solution. The required electrolysis experiment needs to be carried out at a constant temperature of 30 - 40 °C.

[0090] S3: Connect the outlet of the high-pressure plunger pump to the electrolyte inlet 6 of the electrolysis shell 3. The electrolyte flows from the outlet of the high-pressure plunger pump into the circulation pipeline 7 of the electrolyte inlet system through the electrolyte inlet 6; then it flows through the distribution network 8 of the electrolyte inner cavity system, and then the electrolyte passes through the jet slit 14 of the T-shaped workpiece groove 4 and is evenly sprayed onto the T-shaped workpiece.

[0091] Install the electrolysis device on the guide rail slider, and fix the T-shaped workpiece 0.5 mm below the jet slit of the electrolysis device. Connect the anode of the pulse power supply to the T-shaped workpiece through a wire, and connect the cathode to the electrolyte through the cathode wire interface of the electrolysis device. Adjust the pressure of the high-pressure plunger pump to 5 - 10 MPa to ensure that the electrolyte circulates at a constant flow rate in the electrolysis device, container, and high-pressure plunger pump fuel tank for 1 - 2 minutes. Start the pulse power supply, adjust it to the constant current mode, and at the same time start the guide rail switch. The slider reciprocates at a speed of 0.5 mm / s, and the maximum moving distance is 100 mm. Start the experiment.

[0092] S4: After the experiment, the workpiece is cleaned with deionized water, and the surface of the workpiece is measured using a three-dimensional profilometer and a friction and wear tester, and the experimental results are recorded.

[0093] When the current is 8 - 10 A and the electrolysis is carried out for 30 minutes, the roughness of the chamfer and the plane of the T-shaped workpiece obtained is controlled within 2.33 - 2.56 μm, achieving uniform and smooth electrolysis of the T-shaped workpiece.

[0094] Without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The following further elaborates on the invention in detail with reference to the drawings and specific embodiments.

[0095] Embodiment 1

[0096] The embodiment of the present invention provides a jet electrolysis device for electrolyzing a T-shaped workpiece, including an electrolysis shell 3, a sealing cover 2, a slider connecting member 1, a T-shaped workpiece groove 4, a cathode wire interface 5, an electrolyte inlet 6, an electrolyte inlet system, and an electrolyte inner cavity system.

[0097] As Figure 1 and Figure 2 shown, the slider connecting member 1 is arranged on the top of the sealing cover and is fixedly connected to the sealing cover. The connection method is by means of bolt and screw holes. The function of the slider connecting member 1 is: to connect with the slider on the guide rail, drive the slider to move through the rotation of the guide rail, and further drive the electrolysis device to move.

[0098] The sealing cover 2 is installed on the top of the electrolysis shell 3. Specifically, the electrolysis shell 3 and the sealing cover 2 can be connected by setting screw threads and screw holes. The function of the sealing cover 2 is to achieve a sealing effect and prevent the electrolyte from overflowing.

[0099] The electrolysis shell 3 further includes a cathode wire interface 5, an electrolyte inlet 6, and a frustum 15. The electrolysis shell 3 is made of stainless steel material, having strong corrosion resistance, high pressure resistance, high temperature resistance and other stabilities, and a long service life.

[0100] Specifically, the cathode wire interface 5 is arranged on one of the two side walls of the electrolysis shell 3 for connecting the cathode wire of the pulsed power supply. The frustum 15 is arranged on the two side walls inside the electrolysis shell for forming an interference fit with the electrolyte inner cavity system. The two side walls of the electrolysis shell 3 are both provided with electrolyte inlets 6. The function of the electrolyte inlet 6 is to ensure that the electrolyte flows from the electrolyte storage tank into the electrolyte inlet system of the jet electrolysis device, and both side walls are provided with electrolyte inlets, ensuring that the electrolyte flows into the electrolyte inlet system from both sides simultaneously, which is beneficial to the mixing of the electrolyte in the electrolyte inlet system.

[0101] As Figure 3As shown in the figure, the electrolyte inlet system includes a circulation pipeline 7 provided with a circulation pipeline inlet 9 and a circulation pipeline outlet 10; the circulation pipeline 7 is made of stainless steel material, having the advantages of corrosion resistance, high pressure resistance, high temperature resistance, and long service life.

[0102] Specifically, the circulation pipeline 7 consists of four square pipelines connected end to end, and the cross-section of the enclosed area in the middle is rectangular. The circulation pipeline 7 is connected to the electrolytic cell 3 by spot welding, and the problem of easy deformation in overall welding is solved by the method of spot welding; further, the circulation pipeline 7 is hermetically connected to the electrolytic cell 3 to ensure that the electrolyte smoothly enters the circulation pipeline and prevent the electrolyte from leaking out.

[0103] On the upper surface of the circulation pipeline 7, there are a plurality of circulation pipeline outlet holes 10 communicating with the circulation cavity of the circulation pipeline 7. The circulation pipeline outlet holes 10 are evenly and symmetrically distributed on the four square pipelines, ensuring that after the electrolyte enters the circulation cavity of the circulation pipeline, it evenly flows into the electrolyte inner cavity system through the electrolyte outlet holes.

[0104] On the opposite side walls of the circulation pipeline 7, there are circulation pipeline inlet ports 9 communicating with the circulation cavity of the circulation pipeline 7, and the diameter of the circulation pipeline inlet port 9 is the same as that of the electrolyte inlet port 6, ensuring that after the circulation pipeline is fixedly connected to the electrolytic cell, the circulation pipeline inlet port 9 completely coincides with the electrolyte inlet port 6.

[0105] As Figure 4 shown in the figure, the electrolyte inner cavity system includes a distribution network 8 provided with a liquid inlet 11 above the distribution network, a first surface liquid inlet on the surface of the distribution network, and a second surface liquid inlet on the surface of the distribution network, ensuring that the electrolyte is ejected from the jet slit 14 at a constant pressure flow rate to achieve the expected experimental effect and reduce experimental errors.

[0106] The distribution network 8 is in the shape of a cuboid, with an internal cavity structure for accommodating the electrolyte and mixing the electrolyte; the distribution network 8 is made of stainless steel material, having the advantages of corrosion resistance, high pressure resistance, high temperature resistance, and long service life.

[0107] On the upper surface of the distribution network 8, there is a liquid inlet 11 above, and on the front and back surfaces of the distribution network 8, there are surface liquid inlets 12 and 13. The liquid inlet 11 above is evenly arranged on both sides of the upper surface, with no liquid inlet design in the middle, forming a straight line perpendicular to the two side walls without a liquid inlet. The liquid inlet 11 above is symmetrically distributed on both sides of this straight line. This design is to ensure that after the electrolyte flows out from the circulation pipeline outlet hole 10, it enters the distribution network at the same pressure and flow rate, avoiding the pressure difference and different flow rates caused by setting liquid inlets in the middle and on both sides simultaneously.

[0108] The first uniform mesh surface liquid inlet 12 and the second uniform mesh surface liquid inlet 13 are arranged on the front and back of the uniform mesh 8 from top to bottom. Preferably, the diameter of the first uniform mesh surface liquid inlet is 2 mm, which can reduce the inlet resistance and enable the overflowing electrolyte to enter the uniform mesh structure evenly and quickly. In cooperation with the design of the diameter of the liquid inlet 13 of the T-shaped part structure as 1 mm, by restricting the flow rate and balancing the flow of each path, the electrolyte is prevented from flowing unevenly, and all the electrolyte can enter the uniform mesh structure. Through the buffering effect of the liquid inlet 11 above the uniform mesh, the first uniform mesh surface liquid inlet 12 and the second uniform mesh surface liquid inlet 13, the electrolyte enters the uniform mesh evenly, and then ensures that the electrolyte is ejected from the jet slit 14 at a constant pressure flow rate, realizing the uniform electrolysis of the T-shaped workpiece.

[0109] Slit structures 16 are provided on the opposite side walls of the uniform mesh 8 for an interference fit with the frustum 15 of the electrolytic cell to ensure the stability and sealing of the structure. Since the size of the uniform mesh is smaller than that of the electrolytic cell, after the uniform mesh is connected to the electrolytic cell, there is a certain gap between the first uniform mesh surface liquid inlet, the surface liquid inlet 13 and the electrolytic cell 3, enabling the electrolyte to enter the uniform mesh through the surface liquid inlet 12 and the surface liquid inlet 13.

[0110] From Figure 2 It can be seen that the uniform mesh 8 is arranged below the circulation pipeline 7. The outer diameter dimension between the two side walls of the uniform mesh 8 is the same as the inner diameter dimension between the two side walls of the circulation pipeline 7, and the uniform mesh is in contact with the circulation pipeline, facilitating the reflux of the electrolyte into the uniform mesh; the outer diameter dimension of the long side surface of the uniform mesh 8 is smaller than the inner diameter dimension of the long side surface of the circulation pipeline 7, ensuring that the electrolyte flows back into the uniform mesh evenly through the first uniform mesh surface liquid inlet 12 and the second uniform mesh surface liquid inlet 13.

[0111] As Figure 2 shown, the main body of the T-shaped workpiece groove 4 is located in the inner cavity of the electrolyte inner cavity system. The lower end of the main body of the T-shaped workpiece groove 4 is hermetically connected to the lower end of the cavity with two open ends formed by enclosing with the electrolytic cell 3. The flange around the T-shaped workpiece groove 4 is hermetically connected to the bottom side wall of the uniform mesh 8, and the web of the T-shaped workpiece groove 4 is located in the cuboid cavity of the uniform mesh 8. The T-shaped workpiece groove 4 is provided with a shaped jet slit 14, and the jet slit 14 is T-shaped.

[0112] As Figure 7 shown, the jet nozzle designed in the present invention adopts a "T" - shaped structure. By arranging the jet slit inside the T-shaped workpiece groove and setting the jet slit to be shaped with the T-shaped workpiece groove, it is arranged along the horizontal direction, vertical direction and horizontal direction of the T-shaped workpiece groove, extending to the inside and top of the T-shaped workpiece groove, forming a "T" - shaped jet slit. This shape of the jet slit enables the electrolyte to be sprayed onto all surfaces and chamfers of the T-shaped workpiece, having good accessibility.

[0113] Preferably, the size of the jet slit is 1 mm. If the size of the jet peak is too large, the jet velocity and impact force will be reduced, and the reactants generated on the workpiece surface may not be completely washed away and adhered to the workpiece surface, resulting in an increase in the surface roughness of the workpiece and a decrease in the electrolysis efficiency. If the size of the jet peak is too small, air entrainment is likely to occur under high-pressure conditions, leading to jet atomization. At the same time, the jet flow rate may be limited, reducing the jet efficiency.

[0114] Example 2

[0115] The present invention provides a jet electrolytic machining system for electrolyzing T-shaped workpieces. The jet electrolytic machining system includes a jet electrolytic device, a high-pressure plunger pump, a machining tank, a guide rail, a power supply, and a motor.

[0116] As Figure 8 shown, the high-pressure plunger pump includes a pressure pump 22 and an electrolyte storage tank 23. The pressure pump 22 is located above the electrolyte storage tank 23 and is fixedly connected to the electrolyte storage tank 23. The function of the pressure pump 22 is to provide pressure to ensure that the electrolyte smoothly passes through the electrolyte inlet 6, then through the circulation pipeline 7, the distribution network 8, and finally is evenly sprayed onto the T-shaped workpiece through the jet slit 14 under the action of pressure. At the same time, the pressure provided by the pressure pump enables the electrolyte to have a relatively large flow rate, so that the debris generated during the electrolysis process can be smoothly discharged from the surface and chamfer of the T-shaped workpiece.

[0117] The electrolyte storage tank 23 is located below the pressure pump 22. The function of the electrolyte storage tank 23 is to store the electrolyte and provide the electrolyte to the jet electrolytic device under the action of pressure.

[0118] The function of the machining tank 21 is: on the one hand, it can fix the T-shaped workpiece, and on the other hand, it is used to receive the electrolyte after electrolysis that is ejected from the jet slit 14 of the jet electrolytic device. In order to fix the T-shaped workpiece at an appropriate height, the machining tank 21 can also include a support frame for supporting the T-shaped workpiece and adjusting the relative position between the T-shaped workpiece and the electrolytic device. In addition to placing a support frame in the machining tank 21, the relative distance between the electrolytic device and the T-shaped workpiece can also be adjusted by moving the guide rail up and down.

[0119] The guide rail includes a slider, and the slider is detachably connected to the slider connector 1 of the jet electrolytic device. The guide rail is fixed on the guide rail frame, and the guide rail is controlled by a motor to rotate at a constant speed. The guide rail and the slider are connected by a lead screw, so that the uniform movement of the slider is driven by the rotation of the guide rail, and further drives the overall electrolytic device to move uniformly on the T-shaped workpiece in a direction parallel to the vertical and horizontal planes of the T-shaped workpiece, ensuring that the electrolyte is evenly sprayed onto the workpiece surface to make the electrolysis more uniform and smooth.

[0120] During the electrolysis process, the anode wire of the pulsed power supply is connected to the T-shaped workpiece, and the cathode wire of the pulsed power supply is connected to the electrolyte through the cathode wire interface 5. The high-speed flowing electrolyte acts as the cathode; thus, there is no need to design a cathode plate, avoiding the wear and loss of the cathode workpiece.

[0121] Furthermore, the liquid outlet of the high-pressure plunger pump is connected to the electrolyte inlet 6, and the liquid inlet of the high-pressure plunger pump is connected to the processing tank. By setting the pressure, the high-pressure plunger pump makes the electrolyte enter the circulation pipeline 7 from the electrolyte container through the liquid inlet 9 of the circulation pipeline at a constant flow rate, and flow into the liquid inlet 11 above the uniform distribution net from the liquid outlet 10 of the circulation pipeline 7 under a constant pressure. The overflowing electrolyte then flows into the uniform distribution net through the liquid inlet 12 on the surface of the first uniform distribution net and the liquid inlet 13 on the surface of the second uniform distribution net. Finally, under the action of pressure, the electrolyte is evenly and highly sprayed onto the T-shaped workpiece through the jet slit 14 to complete the jet electrolysis machining. Subsequently, the electrolyte flows into the processing tank and returns to the electrolyte container through the liquid inlet pipeline of the high-pressure plunger pump, realizing the recycling of the electrolyte.

[0122] Example 3

[0123] The embodiment of the present invention provides a jet electrolysis process for electrolyzing a T-shaped workpiece, including the following steps:

[0124] S1: Pretreat the surface of the T-shaped workpiece made of Ti22Al25Nb. First, use an alcohol solution to deeply clean the workpiece to remove metal oxide impurities on the workpiece surface, and then use deionized water to clean the workpiece. After drying, it is ready for use.

[0125] S2: Configure the required electrolyte: The electrolyte components are sodium chloride NaCl and potassium bromide K2Br solution. The required electrolysis experiment needs to be carried out at a constant temperature of 30 - 40 °C. Add tap water to the high-pressure plunger pump box, and use a heating rod and a constant temperature numerical control instrument to set the temperature at 37 °C to maintain water bath heating. Prepare a 15L container, put 10L of pure water into the box, and after the water temperature is constant, add 7kg of NaCl powder and 6kg of BrK powder, and stir well until dissolved to prepare a saturated electrolytic solution. According to the mass percentage concentration, NaCl is 26.8% and KBr is 43%.

[0126] S3: Connect the liquid outlet of the high-pressure plunger pump to the liquid inlet of the electrolysis device, and connect the liquid inlet of the high-pressure plunger pump to the container for placing the electrolyte. Install the electrolysis device on the guide rail slider, and fix the T-shaped workpiece 0.5 mm below the jet slit of the electrolysis device. Connect the anode of the pulsed power supply to the T-shaped workpiece through a wire, and connect the cathode to the electrolyte through the cathode wire interface of the electrolysis device. Adjust the pressure of the high-pressure plunger pump to 5 - 10 MPa to ensure that the electrolyte circulates at a constant flow rate in the electrolysis device, the container, and the fuel tank of the high-pressure plunger pump for 1 - 2 minutes. Start the pulsed power supply, adjust it to the constant current mode, set the current magnitude to 8 - 11 A respectively, and at the same time start the guide rail switch. The slider reciprocates at a speed of 0.5 mm / s, and the maximum moving distance is 100 mm to start the experiment.

[0127] S4: After the experiment, clean the workpiece with deionized water, and use a three-dimensional profiler and a friction and wear tester to measure the surface of the workpiece, and record the experimental results.

[0128] When the current magnitude is 8 - 11 A, after electrolysis for 30 minutes, the obtained roughness and loss amount are shown in Table 1:

[0129] Table 1. Roughness and loss amount obtained after electrolysis for 30 minutes when the current magnitude is 8 - 11 A

[0130]

[0131] The above table shows the electrolysis data under the condition of 30 min. It can be seen from the data in Table 1 that both the roughness and the loss amount increase with the increase of the current. When the current is greater than 11 A, the roughness increases rapidly. Therefore, the current should be controlled within the range of 8 - 10 A.

[0132] When the current magnitude is 8 - 10 A, after electrolysis for 30 minutes, overall electrolysis is achieved for each plane and chamfer of the T-shaped workpiece. The roughness of the chamfer and plane of the T-shaped workpiece is controlled within 2.33 - 2.56 μm. Therefore, the jet electrolysis process of the embodiment achieves an efficient and uniform electrolysis effect on the T-shaped workpiece.
