Abstract
Description
Technical Field
[0001] The utility model relates to a filtering device, in particular to a cutting liquid filtering device for wire cutting. Background Art
[0002] Wire EDM is a commonly used workpiece processing method in industrial production and is widely used in the manufacturing industry. In the existing technology, wire EDM mainly relies on cutting fluid to cut the workpiece, and the cutting fluid also plays a role in cooling and chip removal.
[0003] However, during the machining process, waste residue generated when cutting the workpiece circulates with the cutting fluid and participates in the cutting process. When the debris in the cutting fluid accumulates to a certain proportion, this debris will gather together and adhere to the cutting fluid delivery pipe of the wire saw body, which can easily cause blockage of the cutting fluid delivery pipe.
[0004] In order to ensure machining accuracy and orderly processing of machining operations, it is necessary to design a cutting fluid filtering device for wire cutting. Utility Model Content
[0005] In order to overcome the shortcoming of the prior art that the cutting fluid cannot be separated from the debris, the technical problem of the utility model is to provide a cutting fluid filtering device for wire cutting.
[0006] The technical implementation scheme of the present utility model is: a cutting liquid filtering device for wire cutting, comprising a bracket, a wire cutting machine body, a filter barrel, a first filter screen and a baffle. The bottom of the wire cutting machine body is connected to the filter barrel installed on the bracket. The filter barrel is used to collect the cutting liquid after cooling the cutting part of the wire cutting machine body. A first filter screen is provided at the bottom of the filter barrel. The first filter screen has a conical structure with a high middle part and low surroundings. Arc holes are opened on both sides of the filter barrel, and a baffle is slidably connected to the arc holes of the filter barrel.
[0007] More preferably, a collecting shell is fixedly connected to the arc-shaped hole of the filter barrel, the collecting shell is communicated with the filter barrel through the arc-shaped hole, and a limiting block is fixedly connected to the side of the collecting shell facing the filter barrel.
[0008] More preferably, a storage frame is slidably connected to the interior of the collection shell, a second filter screen is fixedly connected to one side of the bottom of the storage frame, and the storage frame can slide in and out of the collection shell.
[0009] More preferably, a motor is installed on the middle side of the bottom of the filter barrel, and the output shaft of the motor extends into the interior of the filter barrel and connects with a scraper movably connected to the interior of the filter barrel.
[0010] More preferably, a mounting ring is fixedly connected to the side wall of the filter barrel, and the limiting rod passes through the mounting ring and engages with the protruding part of the baffle. When the limiting rod is inserted into the protruding part of the baffle, the baffle blocks the arc-shaped hole of the filter barrel. When the limiting rod is pulled out of the protruding part of the baffle, the baffle slides downward.
[0011] More preferably, a collecting frame is installed at the lower part of the bracket, a drain pipe is fixedly connected to the bottom of the collecting frame, and the collecting frame is arranged below the filter barrel.
[0012] More preferably, a rubber pad is fixedly connected to the side of the baffle facing the interior of the filter barrel, and the rubber pad is used to seal the gap between the filter barrel and the baffle.
[0013] Compared with the existing technology, the utility model has the following advantages: 1. The utility model effectively intercepts the debris generated during the cutting process by setting a first filter net at the bottom of the filter barrel, thereby realizing the separation of the debris and the cutting fluid. The filtered water can be collected by the collection frame and discharged to a specific container through a drain pipe for reuse, saving costs while complying with the principles of environmental protection and recycling.
[0014] 2. This utility model features a linkage mechanism between a limit rod and a baffle. When the first filter screen accumulates too much debris, the limit rod can be operated to release the baffle, causing it to slide down, thereby opening the passage between the filter barrel and the collection shell. This design effectively prevents the filter barrel from being clogged by excessive debris.
[0015] 3. The scraper in the utility model is designed with a certain inclination angle, and its length is equal to the inner diameter of the filter barrel, which ensures that the scraper can scrape all directions inside the filter barrel and effectively prevents debris from remaining.

DETAILED DESCRIPTION
[0021] First of all, it should be noted that in the various described embodiments, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.
[0022] Embodiment: A cutting fluid filtering device for wire cutting, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a bracket 1, a wire cutting machine body 2, a filter barrel 3, a first filter screen 4 and a baffle 5. The wire cutting machine body 2 is installed on the top of the bracket 1. The bottom of the wire cutting machine body 2 is connected to the filter barrel 3 installed on the bracket 1. The filter barrel 3 is used to collect the cutting liquid after cooling the cutting part of the wire cutting machine body 2. The first filter screen 4 is provided at the bottom of the filter barrel 3. The first filter screen 4 is a conical structure with a high middle part and low surroundings. Arc holes are opened on both sides of the filter barrel 3. The arc holes of the filter barrel 3 are slidably connected with a baffle 5. Here, the baffle 5 is arranged at the bottom of the outer wall of the filter barrel 3, and a slide groove is provided at the arc hole of the outer wall of the filter barrel 3. The baffle 5 slides into the slide When the baffle 5 is in the groove, the baffle 5 blocks the arc-shaped hole of the filter barrel 3. When the limiting rod 13 is inserted into the protruding part of the baffle 5, the limiting rod 13 limits the baffle 5, so that the baffle 5 can block the arc-shaped hole of the filter barrel 3. When the limiting rod 13 is pulled out of the protruding part of the baffle 5, the limiting rod 13 no longer limits the baffle 5, and the baffle 5 slides downward under the influence of gravity, and the rubber pad 6 is fixed to one side of the baffle 5 and the area of the rubber pad 6 is larger than the area of the side wall of the baffle 5, so that when the baffle 5 blocks the arc-shaped hole of the filter barrel 3, the rubber pad 6 is squeezed and deformed and fills the gap between the baffle 5 and the filter barrel 3, so that the sealing effect is optimized, preventing the cutting fluid from flowing out without being filtered.
[0023] like Figure 3 and Figure 4 As shown, a collecting shell 9 is fixedly connected to the arc-shaped hole of the filter barrel 3, the arc-shaped hole of the filter barrel 3 is located above the first filter screen 4, and the lowest point of the arc-shaped hole of the filter barrel 3 is flush with the lowest point of the first filter screen 4, and the collecting shell 9 is connected to the filter barrel 3 through the arc-shaped hole, and the collecting shell 9 is fixedly connected to the limiting block 16 on the side facing the filter barrel 3. Here, when the baffle 5 slides downward, the baffle 5 is limited by the limiting block 16, so that the baffle 5 is fixed on the limiting block 16 to prevent the baffle 5 from falling off. The collecting shell 9 is located below the first filter screen 4 to facilitate the collection of debris.
[0024] like Figure 3As shown, a storage frame 10 is slidably connected to the inside of the collection shell 9, and a second filter screen 11 is fixedly connected to one side of the bottom of the storage frame 10. The storage frame 10 can slide in and out of the collection shell 9. Here, the storage frame 10 in the collection shell 9 can collect the debris in a concentrated manner, and at the same time, the storage frame 10 can slide outward after the work is completed, so as to facilitate the subsequent processing of the debris in the storage frame 10. At the same time, the design of the second filter screen 11 can filter part of the cutting liquid driven by the scraper 8 when scraping to ensure the filtration efficiency.
[0025] like Figure 2 and Figure 3 As shown, a motor 7 is installed on the middle side of the bottom of the filter barrel 3, and the output shaft of the motor 7 extends into the interior of the filter barrel 3 and is connected to a scraper 8 that is movably connected to the interior of the filter barrel 3. Here, the scraper 8 has a certain inclination angle, and the width of the scraper 8 is equal to the internal diameter of the filter barrel 3, so that the scraper 8 can scrape the filter barrel 3 in all directions to prevent debris from remaining in the filter barrel 3.
[0026] like Figure 3 As shown, mounting rings 12 are fixedly connected to the front and rear symmetrical side walls of the filter barrel 3, and both ends of the "U"-shaped limiting rod 13 pass through the mounting ring 12 and are plugged into the protruding part of the top of the baffle 5. When the limiting rod 13 is inserted into the protruding part of the baffle 5, the baffle 5 blocks the arc-shaped hole of the filter barrel 3. When the limiting rod 13 is pulled out of the protruding part of the baffle 5, the baffle 5 slides downward onto the limiting block 16, thereby releasing the blockage of the arc-shaped hole of the filter barrel 3. At this time, the debris on the first filter screen 4 can move into the collection shell 9 through the arc-shaped hole.
[0027] like Figure 4 As shown, a collecting frame 14 is installed at the lower part of the bracket 1, and a drain pipe 15 is fixedly connected to the bottom of the collecting frame 14. The collecting frame 14 is arranged below the filter barrel 3. Here, the collecting frame 14 can collect the filtered cutting liquid, and the collecting frame 14 is conical in design, so that the filtered cutting liquid flows to the middle and is discharged to a specific container through the drain pipe 15 in the middle for reuse.
[0028] This device is used in material cutting. During the workpiece cutting process, a large amount of debris is usually generated, and these debris will flow from the inside of the wire cutting machine body 2 to the inside of the filter barrel 3 along with the cutting fluid. At this time, the first filter screen 4 set at the bottom of the filter barrel 3 can intercept the debris, thereby separating the debris from the cutting fluid. The filtered cutting fluid will be collected by the collection frame 14 below the filter barrel 3 and discharged to a specific container through the middle drain pipe 15 for reuse. To prevent excessive accumulation of debris in the first filter screen 4 and clogging of the filter barrel 3, when the debris needs to be cleaned, the limit rod 13 can be pulled outward to disconnect the limit rod 13 from the baffle 5, so that the baffle 5 is no longer limited by the limit rod 13, and the baffle 5 slides downward, thereby connecting the filter barrel 3 with the collection shell 9. At the same time, the motor 7 is started, and the output shaft of the motor 7 drives the scraper 8 to rotate. During the rotation, the scraper 8 can concentrate the debris and squeeze the debris so that it passes through the arc-shaped hole of the filter barrel 3 and falls into the collection shell 9. Due to the conical design of the first filter screen 4, the debris moves downward along the inclined surface of the first filter screen 4, and thus falls into the arc-shaped hole of the filter barrel 3, thereby achieving the filtering effect.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
