Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting machine technology, specifically to a cutting fluid tank for a small multi-wire cutting machine. Background Technology

[0002] The cutting fluid tank of a small multi-wire cutting machine is the core of the cutting fluid circulation system, and its design must take into account storage, circulation, cooling, and filtration functions. A reasonable tank structure can significantly improve cutting efficiency, accuracy, and equipment lifespan, while reducing maintenance costs.

[0003] In multi-wire cutting, the cutting fluid tank usually has the function of filtering the cutting fluid. However, when the filter screen is filtered to a certain extent, the impurities inside it will cause blockage, which will affect the filtration of the filter screen. In addition, cleaning requires manual cleaning by staff, which is slow and cannot perform filtration work during cleaning, thus affecting the operation.

[0004] A cutting fluid tank for a small multi-wire EDM machine is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting fluid tank for a small multi-wire cutting machine, in order to solve the problems mentioned in the background art. Currently, in the small multi-wire cutting process, the cutting fluid tank usually has the function of cutting fluid filtration. However, when the filter screen filters to a certain extent, the impurities inside it will cause blockage, which will affect the filtration of the filter screen. Moreover, cleaning requires manual cleaning by workers, which is slow and cannot perform filtration work during cleaning, thus affecting the operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting fluid tank for a small multi-wire cutting machine, comprising a device body and a wire cutting structure mounted on the device body;

[0007] A cutting fluid tank body is fixedly installed on the reverse side of the device body, and a pump is installed on the reverse side of the device body. The suction end of the pump is fixedly installed with the cutting fluid tank body. A water spray pipe is installed inside the device body, and a water supply pipe is fixedly connected between the pump and the water spray pipe. A filter screen is fixedly installed inside the cutting fluid tank body.

[0008] Also includes:

[0009] A cleaning assembly is installed on the cutting fluid tank body. The cleaning assembly includes a connecting plate, which is fixedly connected to the cutting fluid tank body. A fixing plate is fixedly connected to the top of the connecting plate, and a servo motor is installed on one side of the fixing plate.

[0010] Among them, a rotating rod is rotatably connected between the cutting fluid tank body and the fixed plate, and the output end of the servo motor is fixedly connected to the rotating rod, and a rotating rod is fixedly connected to the outside of the rotating rod;

[0011] One side of the rotating rod is fixedly connected to a squeezing block, and one side of the cutting liquid tank body is fixedly connected to a limiting plate, and a supporting plate is slidably connected to the outside of the limiting plate.

[0012] Preferably, a mounting block is fixedly connected to one side of the cutting fluid tank body, and a movable spring is fixedly connected between the mounting block and the support plate.

[0013] Preferably, a connecting strip is fixedly connected to one side of the support plate, and a sliding groove is provided on the top of the cutting liquid tank body.

[0014] Preferably, a sliding rod is slidably connected inside the groove, and the sliding rod is fixedly connected to the connecting strip.

[0015] Preferably, a scraper is fixedly connected to the bottom of the slide bar, and the scraper abuts against the filter screen.

[0016] Preferably, the inside of the cutting fluid tank body is symmetrically provided with a collection component. The collection component includes a collection shell, which can slide inside the cutting fluid tank body. The bottom of the collection shell is provided with multiple leakage holes, and a positioning block is fixedly connected to one side of the collection shell.

[0017] Preferably, a block is fixedly connected to the front of the cutting fluid tank body, and a locking block is slidably connected inside the block, and the locking block passes through the block and engages with the positioning block.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the cutting fluid tank for a small multi-wire cutting machine facilitates automatic cleaning of impurities filtered at the top of the filter screen, thereby avoiding the need to stop the machine for special cleaning of the filter screen, which is detrimental to production. The specific details are as follows:

[0019] 1. When the filter screen needs cleaning, the PLC controller can be used to start the servo motor, causing the rotating rod to rotate. The rotating rod then changes the position of the squeezing block, causing the squeezing block to squeeze the support plate. The movement of the support plate moves the connecting strip and the sliding rod, which in turn moves the scraper, scraping away the impurities filtered on the filter screen. When the squeezing block squeezes the support plate to its maximum distance, the squeezing block detaches from the support plate. At this point, the moving spring returns, causing the support plate to reset, and the scraper resets. When the rotating rod continues to rotate, it will squeeze the support plate again, thus facilitating the cleaning of impurities filtered at the top of the filter screen and enabling convenient supply of cutting fluid.

[0020] 2. The scraper pushes the scraped impurities into the inside of the collection shell. Excess cutting fluid can be filtered out through the drain hole. When it is necessary to clean the impurities inside the collection shell, the locking block can be pulled out to release the limiting of the positioning block. Then the shell can be pulled outward to pull the positioning block, and the collection shell can be pulled out. Then the impurities inside the collection shell can be guided into the trash can, thus cleaning the impurities in the collection shell. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5 The present invention provides the following technical solution:

[0029] A cutting fluid tank for a small multi-wire EDM machine includes a device body 1 and a wire EDM structure 2 mounted on the device body 1. A cutting fluid tank body 101 is fixedly mounted on the reverse side of the device body 1. After completing the tasks of cooling, lubricating, and removing chips from the cutting area, the cutting fluid carries a large amount of chips and impurities back to the cutting fluid tank, thus achieving recycling. While existing technologies include a reflux structure, this application does not depict such a structure. Therefore, in actual production, a reflux structure needs to be added according to the specific circumstances. Furthermore, a pump 102 is mounted on the reverse side of the device body 1. The suction end of the pump 102 is fixedly installed with the cutting fluid tank body 101, and a water spray pipe 103 is installed inside the device body 1. A water supply pipe 104 is fixedly connected between the pump 102 and the water spray pipe 103. A filter screen 105 is fixedly installed inside the cutting fluid tank body 101. A cleaning assembly 3 is installed on the cutting fluid tank body 101. The cleaning assembly 3 includes a connecting plate 301, which is fixedly connected to the cutting fluid tank body 101. A fixing plate 302 is fixedly connected to the top of the connecting plate 301, and a servo motor 303 is installed on one side of the fixing plate 302.

[0030] A rotating rod 304 is rotatably connected between the cutting fluid tank body 101 and the fixed plate 302, and the output end of the servo motor 303 is fixedly connected to the rotating rod 304. A rotating rod 305 is fixedly connected to the outside of the rotating rod 304. A pressing block 306 is fixedly connected to one side of the rotating rod 305, and a limiting piece 307 is fixedly connected to one side of the cutting fluid tank body 101. Figure 2 - Figure 4 As shown, the cutting fluid tank body 101 filters the internal cutting fluid through the filter screen 105 to ensure the quality of the cutting fluid and prevent impurities from affecting the cutting operation. When the filter screen 105 needs to be cleaned, the servo motor 303 can be started by controlling the PLC controller. Then the servo motor 303 will drive the rotating rod 304 to rotate clockwise. Then the rotating rod 304 will drive the rotating rod 305 to rotate. Then the rotating rod 305 will drive the extrusion block 306 to change its position, so that the extrusion block 306 extrudes the support plate 308. The support plate 308 is slidably connected to the outside of the limiting plate 307.

[0031] A mounting block 309 is fixedly connected to one side of the cutting fluid tank body 101, and a moving spring 310 is fixedly connected between the mounting block 309 and the support plate 308. A connecting strip 311 is fixedly connected to one side of the support plate 308, and a sliding groove 312 is provided on the top of the cutting fluid tank body 101. A sliding rod 313 is slidably connected inside the sliding groove 312, and the sliding rod 313 is fixedly connected to the connecting strip 311. A scraper 314 is fixedly connected to the bottom of the sliding rod 313. Figure 2 - Figure 5As shown, the support plate 308 is squeezed and moves to the left, compressing the moving spring 310. Then, the movement of the support plate 308 will drive the connecting bar 311 and the slide bar 313 to move. Then, the slide bar 313 will drive the scraper bar 314 to move, so that the scraper bar 314 scrapes the impurities filtered on the filter screen 105. When the rotating rod 305 rotates to 180 degrees, the squeezing block 306 will squeeze the support plate 308 to the farthest distance. At this time, when the rotating rod 305 continues to rotate...

[0032] The squeezing block 306 will detach from the support plate 308. At this time, the moving spring 310 will rebound, thereby driving the support plate 308 to reset, that is, the scraper 314 will reset. When the rotating rod 305 continues to rotate, it will squeeze the support plate 308 again, thereby facilitating the cleaning of impurities filtered at the top of the filter screen 105, and thus facilitating the supply of cutting fluid. Secondly, the reciprocating moving structure in this application is different from the reciprocating drive of the ordinary threaded rod in the prior art.

[0033] Maintenance of this application is more convenient because the threaded rod requires professional tools to disassemble and the coaxiality of the nut and the threaded rod needs to be recalibrated during maintenance. However, this application uses a modular design: vulnerable parts such as springs and support plates 308 can be quickly replaced, thereby reducing maintenance difficulty. In addition, the threaded rod requires lubricating oil to maintain lubrication, while the components in this application do not require lubrication: the all-dry mechanical structure avoids oil contamination of the cutting fluid; thus facilitating use, and the scraper 314 abuts against the filter screen 105.

[0034] The cutting fluid tank body 101 is symmetrically equipped with collection components 4. Each collection component 4 includes a collection shell 401, which can slide inside the cutting fluid tank body 101. The bottom of the collection shell 401 has multiple leakage holes 402, and a positioning block 403 is fixedly connected to one side of the collection shell 401. A square block 404 is fixedly connected to the front of the cutting fluid tank body 101. Figure 3 - Figure 5 As shown, the scraper 314 pushes the scraped impurities into the collection shell 401. Excess cutting fluid can be filtered out through the drain hole 402. When it is necessary to clean the impurities inside the collection shell 401, the locking block 405 can be pulled out to release the restriction on the positioning block 403. Then the shell can pull the positioning block 403 outward, and the collection shell 401 can be pulled out. Then the impurities inside the collection shell 401 can be poured into the trash can, thus cleaning the impurities in the collection shell 401. The locking block 405 is slidably connected inside the block 404, and the locking block 405 passes through the block 404 and engages with the positioning block 403.

[0035] Working principle: Before using this cutting fluid tank for a small multi-wire cutting machine, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, the cutting fluid tank body 101 filters the internal cutting fluid through the filter screen 105 to ensure the quality of the cutting fluid and prevent impurities from affecting the cutting operation. When it is necessary to clean the filter screen 105, the servo motor 303 can be started by controlling the PLC controller. Then, the servo motor 303 will drive the rotating rod 304 to rotate clockwise. Then, the rotating rod 304 will drive the rotating rod 305 to rotate. Then, the rotating rod 305 will drive the extrusion block 306 to change its position, so that the extrusion block 306 extrudes the support plate 308. Then, the support plate 308 is extruded and moves to the left, compressing the moving spring 310. Then, the support plate 308 moves to the left. The rotating rod 305 moves the connecting bar 311 and the sliding rod 313, which in turn moves the scraper 314, allowing the scraper 314 to scrape away the impurities filtered on the filter screen 105. When the rotating rod 305 rotates to 180 degrees, the squeezing block 306 squeezes the support plate 308 to its furthest distance. When the rotating rod 305 continues to rotate, the squeezing block 306 disengages from the support plate 308, and the moving spring 310 rebounds, thereby resetting the support plate 308, i.e., resetting the scraper 314. When the rotating rod 305 continues to rotate, it will squeeze the support plate 308 again, thus facilitating the cleaning of impurities filtered on the top of the filter screen 105 and facilitating the supply of cutting fluid.

[0036] The scraper 314 pushes the scraped impurities into the collection shell 401. Excess cutting fluid can be filtered out through the drain hole 402. When it is necessary to clean the impurities inside the collection shell 401, the locking block 405 can be pulled out to release the limiting position of the positioning block 403. Then the shell can be pulled outward to move the positioning block 403, thereby pulling out the collection shell 401. Then the impurities inside the collection shell 401 can be poured into the trash can, thus cleaning the impurities in the collection shell 401.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
