Description

Technical Field

[0001] This application relates to the technical field of EDM equipment, and in particular to a cooling device for an EDM machine. Background Technology

[0002] During the operation of an EDM machine, the coolant plays a crucial role in cooling the electrodes and workpiece and flushing away machining debris. However, as machining progresses, a large amount of iron debris will mix into the recovered coolant. During the recovery process, these iron debris may clog coolant lines, reduce coolant flow efficiency, and even damage components such as the coolant pump, increasing equipment maintenance costs and downtime.

[0003] A search revealed that Chinese Patent Publication No. CN222370576U discloses a circulating cooling structure for an EDM machine, including a cooling box and a cooling pipe. A water pump is fixedly installed at one corner of one of the inner side walls of the cooling box, and the outlet of the water pump is fixedly inserted through the cooling box. A drain head is fixedly inserted at one corner of one of the inner side walls of the cooling box, and a double-connector is provided connecting one end of the drain head and one end of the water pump outlet.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: In existing technologies, the recovered coolant contains a large amount of iron filings. Traditional filter screens are easily damaged by the impact of these iron filings after prolonged use, leading to damage to the filtration equipment. To address the problem of iron filings easily damaging equipment in existing technologies, this application proposes installing magnetic plates in the hollow portion of the baffle plate. This utilizes magnetic force to attract iron filings in the coolant, preventing them from clogging coolant pipes, reducing flow efficiency, and damaging components such as the coolant pump.

[0025] The following is in conjunction with the appendix Figures 1-6 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] This application discloses a cooling device for an EDM machine. For example... Figure 1 As shown, the system includes a workbench 1, on which a coolant recovery tank 2 is mounted, and the coolant recovery tank 2 is connected to an iron filings filtration mechanism. The iron filings filtration mechanism includes a filter box 5 composed of a left splicing part 3 and a right splicing part 4. One end of the filter box 5 is provided with a liquid inlet, and the other end is provided with a liquid outlet 6. Both the left splicing part 3 and the right splicing part 4 are provided with multiple hollow baffles 7. The side walls of the left splicing part 3 and the right splicing part 4 are respectively provided with multiple through holes communicating with the hollow parts of the baffles 7. Each hollow part of the baffle 7 is provided with a magnet 8. The filter box 5 is provided with a fixing component.

[0027] In this embodiment, when the coolant containing iron debris enters the filter box 5 through the inlet, the coolant comes into contact with multiple baffles 7. The magnetic sheet 8 set inside the baffle 7 uses magnetic force to attract the iron debris in the coolant to the surface of the baffle 7, and then flows out from the outlet 6.

[0028] When it is necessary to clean the iron debris inside the filter box 5, the fixing of the left splice 3 and the right splice 4 is released by the fixing component; the magnet 8 in the hollow part of the baffle 7 is pulled out. At this time, the iron debris on the surface of the baffle 7 loses the influence of the magnetic force and begins to fall off the surface of the baffle 7.

[0029] Please see Figure 2 The side walls of the left splicing part 3 and the right splicing part 4 are provided with snap-fit ​​parts 9, and snap-fit ​​parts 9 are snap-fitted with snap-fit ​​rods 10, which are fixedly connected to the corresponding magnet pieces 8.

[0030] In this embodiment, the setting of the snap-fit ​​rod 10 makes it easier for multiple magnet pieces 8 to be inserted into or detached from the hollow part of the corresponding baffle plate 7; the snap-fit ​​part 9 can be a snap-fit ​​base made of flexible plastic material, and the snap-fit ​​part 9 clamps the snap-fit ​​rod 10, so that the snap-fit ​​rod 10 can be more conveniently fixed to the left splicing part 3 or the right splicing part 4.

[0031] Please see Figure 3 and Figure 4 A sealing groove 11 is provided on the side of the right splicing part 4 opposite to the left splicing part 3; a sealing strip 12 adapted to the sealing groove 11 is provided on the side of the left splicing part 3 opposite to the right splicing part 4.

[0032] In this embodiment, the sealing groove 11 and sealing strip 12 improve the sealing performance of the filter box 5 composed of the left splicing part 3 and the right splicing part 4.

[0033] Please see Figure 2 The fixing component includes a first slide rail 13 disposed on the left splicing part 3, a second slide rail 14 disposed on the right splicing part 4, and a sliding block 15 adapted to the first slide rail 13 and the second slide rail 14; the track directions of the first slide rail 13 and the second slide rail 14 are consistent.

[0034] In this embodiment, when the left splicing part 3 and the right splicing part 4 are pre-spliced, the sliding block 15 is slid to the corresponding position to make the splicing of the left splicing part 3 and the right splicing part 4 more stable.

[0035] Please see Figure 2 Locking holes 16 are provided on both the first slide rail 13 and the second slide rail 14; a bracket 17 is provided on the sliding block 15, a sliding seat 18 is provided on the bracket 17, and a locking pin 19 is slidably connected to the sliding seat 18; a compression spring 20 is provided between the locking pin 19 and the sliding seat 18.

[0036] In this embodiment, the locking pin 19 is driven by the compression spring 20 to be inserted into the locking hole 16 of the first slide rail 13 and the locking hole 16 of the second slide rail 14.

[0037] Please see Figure 5The locking pin 19 has a rounded end face away from the sliding seat 18; a push rod 21 is provided on the side wall of the locking pin 19.

[0038] In this embodiment, the rounded corners reduce the contact area between the locking pin 19 and the first slide rail 13, making the sliding block 15 slide more smoothly; the push rod 21 facilitates the operator to pull the locking pin 19 out of the locking hole 16.

[0039] The implementation principle of a cooling device for an EDM machine according to an embodiment of this application is as follows: when coolant containing iron scrap enters the filter box 5 through the inlet, the coolant comes into contact with multiple baffles 7. The magnetic sheet 8 set inside the baffles 7 uses magnetic force to attract the iron scrap in the coolant to the surface of the baffles 7, and then flows out from the outlet 6.

[0040] When it is necessary to clean the iron debris inside the filter box 5, the operator moves the locking pin 19 by pushing the push rod 21 to pull the locking pin 19 out of the locking hole 16, and then slides the sliding block 15 to disengage the sliding block 15 from the first slide rail 13 and the second slide rail 14.

[0041] Remove the snap rod 10 from the snap part 9. At this time, the iron filings on the surface of the baffle plate 7 lose the influence of the magnetic force and begin to fall off the surface of the baffle plate 7.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
