[0002] Slow wire EDM is a type of electrical discharge wire EDM equipment. It uses a continuously moving fine metal wire (called electrode wire) as an electrode to perform pulse spark discharge on the workpiece to remove metal and cut it into shape. It is mainly used to process various complex and precise small workpieces.

[0003] Patent publication number CN217832179U discloses a cooling device for a slow wire EDM cutting machine, including a worktable and a workpiece processing device. The worktable is provided with a splash guard on the side near the workpiece processing device. The splash guard has through holes for the workpiece processing device to pass through at the positions corresponding to the positions of the workpiece processing device and the working fluid spraying device. The splash guard is provided with a cover at the position corresponding to the through holes. The splash guard has a plurality of grooves along the rotation diameter direction of the through holes. The cover is provided with a stop bar at the position corresponding to the groove. The stop bar and the groove are configured with an interference fit, thereby improving the service life of the slow wire EDM cutting machine.

[0004] However, the cooling water circulation device in this patent directly recycles the coolant after use. But when the coolant cools the workpiece during processing, it generates a large amount of metal debris. If the unfiltered coolant is directly recycled and reused, the metal debris can easily clog the nozzle. Utility Model Content

[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, this slow wire EDM water-cooling structure significantly improves the cleanliness and circulation efficiency of the coolant by incorporating a detachable filter structure. Specifically, a first spiral plate is suspended and fixed within the machining tank, and a second spiral plate and filter plate are installed on top of it. This allows the coolant containing metal debris to be effectively filtered by the filter plate during recirculation, trapping the metal debris above the filter plate and preventing it from re-entering the circulation system with the coolant. This structure not only prevents the nozzle from clogging due to debris accumulation but also extends the service life of the coolant and reduces equipment maintenance frequency and operating costs. At the same time, the second spiral plate is quickly positioned and fixed using positioning components, ensuring filtration stability while facilitating disassembly and cleaning, thus improving the practicality and ease of operation of the equipment.

[0014] 2. Compared with existing technologies, this slow wire EDM water-cooled structure further optimizes the sealing and connection method between the protective cover and the machining tank, enhancing the equipment's protective performance and operational safety. The protective cover achieves precise positioning through the sliding engagement of the guide block and the guide groove. Furthermore, the insertion structure of the first positioning block and the first positioning groove in the locking component ensures the protective cover is securely locked after closing, effectively preventing coolant splashing during machining. In addition, the sealing element at the machining port, through the cooperation of the plug and the positioning pin, achieves flexible sealing at different machining positions, ensuring the airtightness of the machining area while facilitating adjustments to the opening and closing state of the protective cover according to machining requirements.

A positioning pin 10 is inserted into the blind hole 11 and the positioning pin 10 is vertically fixed to the bottom surface of the cover plate 6.

[0019] Working principle: During use, both L-shaped plates 16 are simultaneously moved inward, causing them to move relative to each other. Simultaneously, the spring 26 is compressed. The filter plate 14 is then placed on the first U-shaped plate 13 within the processing groove 2, allowing the second positioning block 23 to insert into the second positioning groove 22, thus fixing the filter plate 14 in place. Next, the workpiece to be processed is placed inside the processing groove 2. Then, the knob 8 is rotated, causing the screw 21 to rotate.

After the coolant is used, it is filtered by the filter plate 14 and then recycled through the circulation mechanism. When the filter plate 14 needs to be cleaned, the knob 8 is rotated to make the first positioning block 20 leave the first positioning groove 19. Then, the protective cover 5 is removed from the top surface of the processing groove 2. Then, the two L-shaped plates 16 are pushed inward to make the two L-shaped plates 16 move relative to each other. At the same time, the spring 26 is compressed to make the second positioning block 23 leave the second positioning groove 22. Then, the filter plate 14 is removed from the processing groove 2 through the L-shaped plate 16 for cleaning.
