Description

Technical Field

[0001] The invention relates to the technical field of electric spark forming machines, in particular to an oil removal device for electric spark forming machines. Background Art

[0002] An EDM machine is a machine that uses electric spark discharge machining technology to manufacture and process metal workpieces. The electrode is the key component that directly generates sparks in EDM. During the EDM machining process, the electrode and the workpiece are respectively connected to the two poles of a pulse power supply. When a pulse voltage is applied between the two, spark discharge will occur. This discharge phenomenon will generate high temperature, causing local vaporization or melting of the workpiece surface, thereby achieving material removal and workpiece processing.

[0003] During the processing of the EDM machine, oil and other impurities often adhere to the surface of the electrode. These oils and impurities will not only affect the stability of the discharge process, resulting in a decrease in processing quality and efficiency, but may also cause wear to the electrode and shorten its service life. Therefore, it is very important to continuously degrease and clean the electrode. At present, when degreasing the electrode on the EDM machine, most of the time, the staff use cleaning tools to wipe the electrode surface to absorb the oil, resulting in the oil on the electrode surface cannot be effectively treated, and the degreasing efficiency is low, which brings inconvenience to subsequent processing and use.

After multiple filtrations through the filter 255, the oil removal filler 256 and the ultrafiltration membrane 257, the oil and impurities in the cleaning liquid are effectively filtered and processed to ensure the recycling of the cleaning liquid.

[0042] Working principle: When the staff needs to degrease the electrodes on the EDM machine, the staff places multiple electrodes to be degreased on the top of the feeding table 53, and then opens the hydraulic cylinder 51 on the left, so that the feeding table 53 moves up. At this time, the staff turns on the first motor 71 and controls the moving table 76 to move to the left, so that the electrode placement rack 10 is close to the feeding table 53. Then, when the height of the feeding table 53 is higher than the electrode placement rack 10, the staff turns on the electric push rods 55 on both sides, so that the push plate 56 pushes the electrode into the interior of the electrode placement rack 10. At this time, the moving table 76 controls the electrode placement rack 10 to move to the center above the first degreasing pool 2, and then the second motor 91 at the rear is turned on, so that the connecting rack 94 drives the electrode placement rack 10 to move to the top of the first degreasing pool 2. The rack 10 descends, so that the electrode rack 10 enters the interior of the first degreasing tank 2 and contacts the cleaning liquid inside the first degreasing tank 2. Then the staff turns on the ultrasonic generator 3 under the first degreasing tank 2. The ultrasonic wave will produce cavitation effect, acceleration effect and straight flow effect in the cleaning liquid. These effects together promote the removal of oil stains. The electrode on the electrode rack 10 is degreased for the first time by ultrasonic cleaning. Then the second motor 91 at the rear is turned on again, so that the electrode rack 10 is moved out of the interior of the first degreasing tank 2, and the movable platform 76 below moves the electrode rack 10 to the top of the second degreasing tank 11. At this time, the connecting rack 94 controls the electrode rack 10 to descend again, so that the electrode rack 10 enters the second degreasing tank 11, the staff turns on the aeration pumps 12 on both sides and the first motor 153. At this time, the aeration plate 14 inside the second degreasing tank 11 starts to aerate, and the shaking plate 159 pushes the electrode rack 10 to shake left and right inside the second degreasing tank 11, so that the cleaning liquid can better penetrate into the oil on the surface of the electrode. The rising and bursting process of the bubbles will produce a certain impact force, which will help to peel the oil from the electrode surface, thereby completing the second degreasing and cleaning of the electrodes inside the electrode rack 10. After the degreasing operation is completed, the staff controls the electrode rack 10 to rise, so that the electrode rack 10 is moved out of the second degreasing tank 11, and then the staff can turn on the fan 17, and the fan 17 injects air into the heating box 1 8, the air is heated by the electric heating wire inside the heating box 18, and the heated air is discharged through the exhaust pipe 21, and the staff turns on the second motor 224 on the left, so that the second gear 223 drives the movable tube 19 to swing back and forth as a whole, and then the electrodes on the surface of the electrode placement rack 10 below are evenly dried through the exhaust pipe 21. At this time, the staff turns on the electric telescopic rod 231 and the rodless cylinder 232, and the output shaft of the electric telescopic rod 231 controls the brush 233 to move above the electrode on the surface of the electrode placement rack 10, and the rodless cylinder 232 controls the brush 233 to move back and forth, so that the brush 233 moves the electrode on the surface of the electrode placement rack 10 back and forth, so that the electrode is fully in contact with the hot air above.The electrode surface dries quickly. After drying, the staff can remove the electrode and reinstall it on the corresponding EDM machine. When the first degreasing tank 2 or the second degreasing tank 11 completes the degreasing operation, the staff can open the corresponding solenoid valve 254 and use the water pump 252 to pump the cleaning liquid inside the first degreasing tank 2 or the second degreasing tank 11 into the filter box 251, so that the filter 255, the degreasing filler 256 and the ultrafiltration membrane 257 can effectively filter the oil and impurities in the cleaning liquid. After filtration, the staff can re-inject the cleaning liquid into the first degreasing tank 2 or the second degreasing tank 11 for subsequent reuse, thereby completing the degreasing and cleaning operation of the electrode on the EDM machine.
