Description

Technical Field

[0001] This utility model relates to the field of electrochemical processing technology, specifically, to an electrode head rinsing device for metal electrolytic cutting. Background Technology

[0002] Electrochemical machining (ECM) is a processing method that removes metallic materials through electrochemical reactions. Its basic principle is based on electrolysis, where an electric current in an electrolyte causes a redox reaction on the workpiece surface, thereby removing the metal. During ECM, the workpiece and electrodes are connected by an electrolyte; as the current flows, the metal surface is electrolyzed into ions and dissolved, forming tiny metal particles, thus achieving material removal.

[0003] In existing processing techniques, after each workpiece is processed, the male and female electrodes separate. Workers then remove the finished workpiece, place the next workpiece in the machine, and begin the next processing cycle. However, when processing a certain workpiece, due to its precision and the fact that some areas are prone to breakage, our company requires rinsing the working surfaces of the male and female electrodes after each processing cycle to remove any adhering debris, ensuring a high level of cleanliness and improving the accuracy of subsequent processing. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0028] Example 1:

[0029] This embodiment provides a rinsing device for electrode heads used in metal electrolytic cutting, specifically as follows: Figures 1-6As shown, the shower device 10 includes:

[0030] A shower pipe, comprising a liquid supply pipe 112 and a nozzle 117, wherein the nozzle 117 is installed at one end of the liquid supply pipe 112 and the other end is connected to a pump body, and the pump body pumps the electrolyte in the storage tank 20 to spray it out of the nozzle 117.

[0031] A guide tube, used to guide the direction of the nozzle 117 and protect the shower pipe, includes a protective tube and a deflector tube 109 connected thereto, the shower pipe passing through the guide tube;

[0032] A displacement component is used to change the position of the guide tube so that the nozzle 117 covers a larger shower area.

[0033] After the cathode head 40 and anode head 50 finish machining the part, the anode head 50 is lifted upwards, at which point the cathode head 40 and anode head 50 separate. The displacement component moves the guide tube, so that the nozzle 117 is positioned between the cathode head 40 and anode head 50. At this time, the nozzle 117 sprays electrolyte onto the machining surfaces of the cathode head 40 and anode head 50, washing away any impurities that may be carried on the machining surfaces. By continuously adjusting the position of the nozzle 117 through the displacement component, the machining surfaces of the cathode head 40 and anode head 50 are completely covered and cleaned. This electrolyte will flow into the electrolytic cell 30 and be collected.

[0034] By thoroughly cleaning the machining surfaces of the cathode head 40 and anode head 50, any metal slag that may adhere to the machining surfaces is completely removed, ensuring a high degree of cleanliness. This provides good preconditions for the machining of the next workpiece, ensuring that the workpiece has the predetermined machining accuracy and improving the yield rate.

[0035] Example 2:

[0036] This embodiment further extends the above embodiment, specifically as follows: Figures 3-6 As shown, the displacement assembly includes a base 101, a guide rod 102, a lead screw 103, a first motor 104, and a slide 105. The guide rod 102 and the lead screw 103 are rotatably connected to the base 101, and the first motor 104 is fixedly connected to it. The output end of the first motor 104 is connected to the lead screw 103. The slide 105 is threadedly connected to the lead screw 103 and slidably connected to the guide rod 102. The guide tube is mounted on the slide 105.

[0037] The base 101 is detachably connected to the liquid storage tank 20 by bolts. When the first motor 104 is started, the first motor 104 drives the lead screw 103 to rotate. At this time, the slide 105 is driven by the lead screw 103 and begins to move laterally under the guidance of the guide rod 102, thereby driving the guide tube to move laterally; thus realizing the lateral spraying function of the nozzle 117.

[0038] Furthermore, a second motor 107 is installed on the slide block 105, and a first gear 106 is installed at the output end of the second motor 107; a plurality of gear rings 110 are provided on the protective tube, the first gear 106 cooperates with the gear rings 110, and the protective tube is installed on the slide block 105.

[0039] When the second motor 107 is started, the first gear 106 drives the first gear 106 to rotate. Since the first gear 106 meshes with the gear ring 110, the gear ring 110 drives the entire protective tube to start moving back and forth, thereby realizing the fitting and rinsing function of the nozzle 117.

[0040] Furthermore, the protective tube includes an outer tube 108 and an inner tube 113, the outer tube 108 and the inner tube 113 are slidably connected, the gear ring 110 is disposed on the outer tube 108, the steering tube 109 is threadedly connected to the outer tube 108, a second gear 114 is mounted on the inner tube 113, and the inner tube 113 is rotatably connected to the slide block 105; the displacement assembly also includes a third motor 111 mounted on the slide block 105, a third gear 115 is mounted on the output end of the third motor 111, and the third gear 115 meshes with the second gear 114.

[0041] When the third motor 111 is started, the third motor 111 drives the third gear 115, the third gear 115 drives the flared sleeve 116, the flared sleeve 116 drives the inner tube 113 to rotate, and the inner tube 113 drives the outer tube 108 to rotate. Since the gear ring 110 is annular, it does not affect its meshing with the first gear 106. At this time, the steering tube 109 starts to rotate, so as to realize that the electrolyte at the nozzle 117 is sprayed upward or downward, completing the rinsing of the cathode head 40 or the anode head 50.

[0042] Furthermore, a flared sleeve 116 is installed on the inner tube 113, and the flared sleeve 116 is trumpet-shaped. The flared sleeve 116 is provided at the end of the inner tube 113 so that the liquid supply tube 112 is attached to the inner surface of the flared sleeve 116. The arc-shaped inner surface of the flared sleeve 116 provides the liquid supply tube 112 with a large bending radius, preventing the liquid supply tube 112 from being excessively bent at this point and thus hindering the pumping of electrolyte, while also preventing excessive wear on the liquid supply tube 112 at the end of the inner tube 113.

[0043] Furthermore, a section of the liquid supply pipe 112 inside the protective pipe is spirally distributed. This spiral section is resilient, and when the protective pipe extends or retracts to change its length, this spiral section of the liquid supply pipe 112 will extend or retract adaptively, while the portion of the liquid supply pipe 112 and the pump body located in the liquid storage tank 20 will not move, thereby preventing the liquid supply pipe 112 from being pulled arbitrarily, causing bending, blockage, excessive wear, etc.

[0044] Furthermore, a collection hopper 118 is installed on the diverting pipe 109, and the collection hopper 118 is bucket-shaped. During rinsing, after the anode head 50 moves away from the cathode head 40, the displacement assembly first adjusts the nozzle 117 to point upwards, then moves it below the anode head 50, and then begins rinsing. At this time, any lumpy workpiece fragments that may fall off the anode head 50 will be caught by the collection hopper 118, while the electrolyte flows away through the filter holes on the collection hopper 118, thus preventing the fragments from falling into the cathode head 40 or the electrolytic cell 30. After rinsing the anode head 50, keeping the nozzle 117 upwards, the nozzle 117 is moved outwards. The workpiece is placed in the residue collection box, and then the displacement component rotates the guide tube so that the nozzle 117 points downward. At this time, the residue collected by the collection bucket 118 will fall into the residue collection box. At the same time, the workpiece in the cathode head 40 is taken out manually. Then the displacement component drives the nozzle 117 to the top of the cathode head 40 and begins to rinse the cathode head 40. After rinsing, the displacement component drives the rinsing pipe away. At this time, the worker puts the workpiece to be processed in the cathode head 40, and then the anode head 50 is pressed down to start a new round of electrochemical processing.

[0045] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
