Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machines, in particular to a high-pressure anti-blocking working fluid filter and a medium-speed wire cutting machine. Background Art

[0002] The working fluid of the wire cutting machine is used to supply cleaning and remove electro-erosion products. The working fluid circulation and filtration system is an important component of the wire cutting machine. Its function is to continuously supply clean working fluid to the discharge area to maintain the stability of the pulse discharge process.

[0003] In the related technology, a search found a solution for a wire cutting filter device for a wire-cutting machine (Announcement No. CN220407352U). The sewage generated during the wire-cutting machine processing is discharged into the filter chamber, and then the filter mesh, quartz sand layer and activated carbon plate arranged in the filter chamber cooperate with each other to achieve the purpose of multi-stage purification of the sewage. Then, by starting the water pump, the purified sewage is re-input into the working fluid used by the wire-cutting machine through the cooperation of the connecting pipe and the drain pipe.

[0004] However, when the output head discharges sewage into the filter, some impurities will be collected by the filter. After a period of use, the impurities accumulate in the filter, causing the filtering effect of the filter to deteriorate. Regular cleaning is required, delaying the filtering work and making it inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a high-pressure anti-blocking working fluid filter and a medium-speed wire cutting machine to solve the problems raised in the above background technology.

[0008] A flushing pump is installed on the side of the holding box, the outlet of the flushing pump is connected to a bifurcated pipe, and a solenoid valve is installed on the bifurcated pipe, the bifurcated pipe is connected to a first nozzle group and a second nozzle group, the first nozzle group and the second nozzle group are installed in the holding box for flushing the filter plate, the two first nozzle groups and the second nozzle groups alternately flush the impurities on the filter plate to prevent the impurities from clogging the filter plate, and ensure that the working fluid passes through the filter plate smoothly.

[0009] Furthermore, the bottoms of the filter box and the holding box are both conical and are equipped with discharge valves to facilitate the discharge of impurities. The lower surface of the holding box is connected to a delivery pump to deliver the filtered working fluid to the medium wire cutting machine for use.

[0010] Furthermore, the auxiliary filter includes a filter box, and a plurality of V-shaped filter plates are plugged into the interior of the filter box. When the V-shaped filter plates collect impurities, the impurities are located on both sides of the V-shaped filter plates, thereby preventing the V-shaped filter plates from being blocked by impurities. The V-shaped filter plates are connected to a sealing cover, which is plugged into the filter box. The sealing cover is pulled to extract the V-shaped filter plates, thereby facilitating cleaning of the V-shaped filter plates.

[0011] A total recovery pipe is installed on the side of the filter box, and the total recovery pipe is connected to several sub-recovery pipes with valves. The sub-recovery pipes are connected to the filter box. If you need to clean a secondary filter, just close the corresponding valve.

[0012] A medium-speed wire cutting machine comprises the above-mentioned high-pressure anti-blocking working fluid filter, so that the working fluid used by the medium-speed wire cutting machine is cleaner and the supply of the working fluid is smoother and more stable.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The recovered working fluid is sent to the filter box through the main recovery pipe and the sub-recovery pipe. Several V-shaped filter plates filter the working fluid. Impurities are piled on both sides of the V-shaped filter plates to ensure that the V-shaped filter plates are not easily blocked. The V-shaped filter plates are pulled out of the filter box using the cover to facilitate cleaning of the V-shaped filter plates. Multiple auxiliary filters will not delay the filtration work.

[0015] (2) The flushing pump extracts the filtered working fluid and provides the working fluid to the first nozzle group and the second nozzle group through the bifurcated pipe. When there are impurities on the filter plate, the first nozzle group and the second nozzle group flush the impurities off the filter plate, ensuring that the working fluid in the filter box enters the storage box more smoothly.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-4 The utility model provides a technical solution: a high-pressure anti-blocking working fluid filter, comprising a filter box 1, a filter bucket 16 is placed inside the filter box 1, and a plurality of auxiliary filters are installed in the filter bucket 16. The filter bucket 16 can collect impurities leaked from the auxiliary filters to prevent excessive impurities from entering the filter box 1;

[0024] The holding box 2 is connected to the filter box 1 through a short tube 3. A filter plate 15 is inserted into the upper surface of the short tube 3. The filter plate 15 blocks impurities in the filter box 1 from entering the holding box 2, ensuring that the holding box 2 contains clean working fluid.

[0025] A flushing pump 5 is mounted on the side of the holding tank 2. The outlet of the flushing pump 5 is connected to a bifurcated pipe 8, and a solenoid valve 9 is mounted on the bifurcated pipe 8. The bifurcated pipe 8 is connected to a first nozzle group 13 and a second nozzle group 14. The first nozzle group 13 and the second nozzle group 14 are mounted in the holding tank 2 for flushing the filter plate 15.

[0026] The two solenoid valves 9 are opened separately to ensure that the filter plate 15 will not be flushed by the first nozzle group 13 and the second nozzle group 14 at the same time, which is conducive to the working fluid flowing to the storage box 2 more quickly.

[0027] In this embodiment, if Figure 1 As shown, the bottoms of the filter box 1 and the holding box 2 are both conical and are equipped with a discharge valve 7. The cone shape helps to collect impurities. The impurities can be discharged by opening the discharge valve 7. The lower surface of the holding box 2 is connected to a delivery pump 6, which delivers the working fluid to the medium-speed wire cutting machine for use.

[0028] In this embodiment, if Figure 3 and Figure 4 As shown, the auxiliary filter includes a filter box 19, and a plurality of V-shaped filter plates 20 are plugged into the interior of the filter box 19. The V-shaped filter plates 20 guide impurities to accumulate on the left and right sides of the filter box 19. The V-shaped filter plates 20 are not easily blocked. The V-shaped filter plates 20 are connected to a cover 18, and the cover 18 is plugged into the filter box 19. The V-shaped filter plates 20 can be pulled out of the filter box 19 through the cover 18, which facilitates cleaning of the filter box 19 and the V-shaped filter plates 20.

[0029] In this embodiment, if Figure 2 As shown, a total recovery pipe 10 is installed on the side of the filter box 1, and the total recovery pipe 10 is connected to several sub-recovery pipes 11 with valves 12. The sub-recovery pipes 11 are connected to the filter box 19. If a sub-filter needs to be cleaned, the valve 12 of the corresponding sub-recovery pipe 11 is closed, and the filtration of the working fluid will not be delayed when cleaning the sub-filter.

[0030] In this embodiment, if Figure 2 、 Figure 3 、 Figure 4 As shown, the surface of the filter box 19 is provided with a plug-in tube 17, and the branch recovery tube 11 is inserted into the plug-in tube 17, which makes it convenient to separate the plug-in tube 17 and the branch recovery tube 11 and can be directly pulled out.

[0031] In this embodiment, if Figure 1 As shown, a handle 4 is fixedly connected to the upper surface of the filter plate 15 , and the handle 4 is used to conveniently pull the filter plate 15 out of the short tube 3 , so as to facilitate cleaning of the filter plate 15 .

[0032] A medium-speed wire cutting machine comprises a high-pressure anti-blocking working fluid filter, a flushing pump 5 extracts the filtered working fluid from a storage box 2 and sends it to the medium-speed wire cutting machine for use.

[0033] Specifically, when in use, the working fluid discharged from the wire cutting machine is sent to the main recovery pipe 10, and the main recovery pipe 10 sends the working fluid to the filter box 19 through several branch recovery pipes 11. The impurities in the working fluid are filtered and collected by the V-shaped filter plate 20. The upward convex V-shaped filter plate 20 is not easily blocked by impurities. The working fluid discharged from the filter box 19 passes through the filter bucket 16 into the filter box 1, and the working fluid in the filter box 1 passes through the filter plate 15 and flows into the holding box 2. The flushing pump 5 extracts the working fluid and sends it to the first nozzle group 13 and the second nozzle group 14 through the bifurcated pipe 8. The two solenoid valves 9 work alternately to avoid the first nozzle group 13 and the second nozzle group 14 from flushing the filter plate 15 at the same time, which is conducive to the working fluid flowing from the filter box 1 to the holding box 2. When there are impurities on the filter plate 15, the impurities are flushed off the filter plate 15 by flushing, thereby extending the cleaning cycle of the filter plate 15 and being more convenient to use.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
