Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric spark forming machine tools, and more specifically, to a working fluid chip removing device for electric spark forming machine tools. Background Art
[0002] An EDM machine is a precision machining device that utilizes the principle of electric spark discharge for metalworking. It is primarily used to process metal parts requiring high hardness, strength, and precision. The working fluid of an EDM machine typically contains a large amount of machining debris. This high volume of debris can cause clogging of the filter during filtration. This clogging makes it difficult to remove the filter during normal operation, hindering debris removal and impacting machining efficiency.
[0003] After searching, a Chinese patent with announcement number CN211170129U discloses a filtering device for the working fluid of an electric spark machine tool. Gas is blown into the liquid storage tank through a blower and an air inlet pipe, and the liquid is filtered through a first filter plate. Due to the gas blowing, the gas pushes the working fluid inside the liquid storage tank to move, accelerating the flow of the liquid. At the same time, the flow of the liquid drives the impurities inside it to move, increasing the contact probability of iron fragments in the working fluid with the adsorption rod and the adsorption column, so that the adsorption rod and the adsorption column can adsorb the iron fragments in the working fluid as much as possible.
[0004] When in use, the adsorption column in the aforementioned patent can only adsorb magnetic metals and is ineffective in adsorbing and removing debris from non-magnetic metals such as titanium alloys. In the aforementioned patent, gas propels the working fluid within the reservoir, which in turn moves impurities within it. However, the gas blows up the working fluid and carries away a small amount of it, causing it to drift near the EDM machine, accelerating its loss and affecting its normal operation.

[0014] The utility model can prevent the working fluid in the liquid storage tank from flowing out by closing the valve, and then pour the additive into the liquid storage tank through the feed pipe. The additive passes through the filter screen partition and contacts the working fluid in the liquid storage tank. The first motor is started, and the operation of the first motor drives the rotating shaft to rotate, thereby driving the stirring blade to rotate. The stirring blade stirs the working fluid and additive in the liquid storage tank and mixes them thoroughly. By adding an appropriate amount of additives, the service life of the working fluid can be extended, effectively improving processing efficiency. In addition, in the mixed powder working fluid, after the working fluid has not been used for a long time, its powder will become uneven in the working fluid. The stirring blade properly stirs the working fluid in the liquid storage tank and makes the mixing more uniform, effectively improving processing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0024] Refer to the instruction manual Figure 1-6 , a working fluid chip removal device of an electrospark forming machine tool in this embodiment includes a liquid storage tank 1, a filter screen partition 12 is fixedly connected to the interior of the liquid storage tank 1, and a support seat 6 is fixedly connected to the bottom end of the liquid storage tank 1. Two guide plates 13 are movably provided on the top of the filter screen partition 12, and the two guide plates 13 are fixedly installed inside the liquid storage tank 1, and two inclined plates 7 are fixedly connected between the bottom end of the filter screen partition 12 and the liquid storage tank 1. A cleaning assembly 8 is provided on the top of the filter screen partition 12, and the cleaning assembly 8 includes a screw 801, a limit rod 802, a scraper 803, two sliders 804, two gaskets 805 and two springs 806. Both ends of the screw 801 are movably connected to the liquid storage tank 1 through bearings, and both ends of the limit rod 802 are fixedly connected to the liquid storage tank 1, and one end of the limit rod 802 and the screw 801 pass through the scraper 803.
[0025] One end of the limiting rod 802 and the lead screw 801 passes through the two sliders 804, and the two gaskets 805 are fixedly mounted on the two sliders 804 respectively. The two springs 806 are movably mounted on the limiting rod 802, and the two ends of the two springs 806 are fixedly connected to the liquid storage tank 1 and the two sliders 804 respectively. A second motor 809 is fixedly installed on one side of the liquid storage tank 1, and the output shaft end of the second motor 809 is fixedly connected to the second bevel gear 808. The rear side of the second bevel gear 808 is meshed with the first bevel gear 807, and one side of the first bevel gear 807 is fixedly connected to the lead screw 801. The top of the liquid storage tank 1 is fixedly connected to the feed pipe 2, and the bottom end of the liquid storage tank 1 is fixedly connected to the discharge pipe 3, and a valve 4 is fixedly mounted on the discharge pipe 3.
[0026] Transparent panels 5 are fixedly connected to both the front and rear sides of the liquid storage tank 1. Through the transparent panels 5, the storage status of debris on the filter screen partition 12 can be observed. A stirring assembly is provided at the bottom of the filter screen partition 12. The stirring assembly includes a first motor 9, a rotating shaft 10, and a stirring blade 11. The first motor 9 is fixedly mounted on the rear side of the liquid storage tank 1. The rear end of the rotating shaft 10 is fixedly connected to the end of the output shaft of the first motor 9. The rotating shaft 10 is movably connected to the liquid storage tank 1 via a bearing. The rear end of the stirring blade 11 is fixedly connected to the rotating shaft 10.
[0027] Among them, after the working fluid has been circulated for a period of time, its performance and quality will decline to a certain extent. Closing the valve 4 can prevent the working fluid in the liquid storage tank 1 from flowing out, and then pouring the additive into the liquid storage tank 1 through the feed pipe 2. The additive passes through the filter screen partition 12 and contacts the working fluid in the liquid storage tank 1. The first motor 9 is started, and the first motor 9 drives the rotating shaft 10 to rotate, thereby driving the stirring blade 11 to rotate. The stirring blade 11 stirs the working fluid and the additive in the liquid storage tank 1 and mixes them thoroughly. By adding an appropriate amount of additives, the service life of the working fluid can be extended, and the processing efficiency can be effectively improved. In the mixed powder working fluid, after the working fluid has not been used for a long time, its powder will become uneven in the working fluid. The stirring blade 11 properly stirs the working fluid in the liquid storage tank 1 and makes it mix more evenly, effectively improving the processing quality.
[0028] The method of using this embodiment is:
[0029] During use, the feed pipe 2 is connected to the liquid outlet pipe of the EDM forming machine by bolts, and the discharge pipe 3 is similarly connected to the input end of the water pump. The working fluid on the EDM forming machine enters the liquid storage tank 1 through the feed pipe 2, and the filter partition 12 filters the working fluid, and the debris remains on the top of the filter partition 12. The water pump extracts the filtered working fluid in the liquid storage tank 1 through the discharge pipe 3 and injects the working fluid into the EDM forming machine, so that the working fluid can be recycled.
[0030] Start the second motor 809, the second motor 809 drives the second bevel gear 808 to rotate, thereby driving the first bevel gear 807 to rotate, and then driving the screw 801 to rotate. Since the scraper 803 is threadedly connected to the screw 801, the limit rod 802 limits the rotation of the scraper 803, so the screw 801 can drive the scraper 803 to move horizontally to the left, thereby driving one of the sliders 804 to move horizontally to the left, and then driving the debris to move to the left. The inclined plate 7 guides the debris, and finally the debris flows out from the left side of the liquid storage tank 1. At the same time, one of the sliders 804 drives the debris to move horizontally to the left. A spring 806 is compressed. When the scraper 803 moves to the right, one of the springs 806 rebounds and drives one of the sliders 804 to move horizontally to the right. The debris can be cleaned while the working fluid of the EDM forming machine is normally filtered. This will not affect the filtering process of the working fluid of the EDM forming machine, ensuring the normal operation of the EDM forming machine, improving the working efficiency of the EDM forming machine and the service life of the flushing equipment. The use effect is good. The two gaskets 805 can improve the sealing between the two sliders 804 and the filter partition 12 to prevent the working fluid from flowing out.
[0031] After the working fluid has been circulated for a period of time or the mixed powder working fluid has not been used for a long time, the valve 4 is closed to prevent the working fluid in the liquid storage tank 1 from flowing out, and then the additive is poured into the liquid storage tank 1 through the feed pipe 2, and the first motor 9 is started to drive the rotating shaft 10 to rotate, thereby driving the stirring blade 11 to rotate, effectively improving the processing efficiency and processing quality.
