[0002] Wire EDM machines, as key equipment for high-precision machining, are widely used in mold manufacturing, aerospace and other fields. However, during their operation, they require the continuous use of a large amount of working fluid (such as emulsified oil) for cooling, insulation and chip removal, which causes the working fluid to mix with metal chips to form waste liquid.

[0003] A search revealed Chinese patent application CN114985858A, which discloses a wire EDM machine with a cleaning device, including a frame; a cutting assembly mounted on the frame for cutting workpieces; and a cleaning assembly located below the cutting assembly for cleaning and separating the working fluid carrying metal debris after cutting, thereby separating the working fluid from the metal debris after cutting for recycling.

Furthermore, it lacks the ability to handle non-magnetic material debris, limiting its practical application. Therefore, there is an urgent need to design a wire cutting machine with a cleaning device to solve these problems. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a wire cutting machine with a cleaning device, which has the following advantages: 1. This wire cutting machine with a cleaning device comprises a drainage hopper, a guide ring, a plug, a drain pipe, a positioning rod, and a positioning groove. The guide ring at the bottom of the drainage hopper slides in conjunction with the drain pipe. The drain pipe is raised and lowered by a lifting drive unit. The automatic sealing and grid-like opening of the bottom of the drainage hopper are achieved by the engagement and disengagement of the positioning rod at the top of the drain pipe and the positioning groove on the side of the plug. The core feature is that when the positioning rod engages with the positioning groove, the bottom of the drainage hopper is sealed, allowing it to collect and temporarily store cutting debris and emulsified oil. When the lifting drive unit moves the drain pipe downwards, the positioning rod disengages from the positioning groove, forming a grid-like opening at the bottom of the drainage hopper. The grid gaps automatically intercept and retain large volumes of processing waste, facilitating subsequent centralized recycling. Emulsified oil and fine debris can drain through the grid gaps. Simultaneously, a mesh bag fixed at the bottom of the drain pipe performs secondary filtration on the drained emulsified oil, further separating residual fine debris. The separated waste liquid finally falls into the waste liquid tank below. This design achieves two-stage automatic separation of solids and liquids in the waste liquid without machine shutdown or manual intervention, significantly improving cleaning efficiency and separation effect, reducing the difficulty of subsequent waste liquid treatment, and effectively preventing clogging of the diversion hopper, ensuring the smooth continuous operation of the wire cutting machine.

[0017] 2. This wire cutting machine with a cleaning device, by setting up a connecting rod, a threaded seat, a sliding seat, and a slot, allows the threaded part of the first bolt to be separated from the threaded seat by rotating the first bolt with a knob, thus separating the threaded seat from the lifting platform. After disconnecting the connection between the threaded seat and the lifting platform, the push rod motor is pushed towards the opening of the slot, and the sliding seat slides out from the opening of the slot, thereby removing the push rod motor from the side of the cutting box for easy installation and maintenance. Both ends of the connecting rod are fixedly connected to second bolts, which are inserted into the first and second collars respectively, and then locked with nuts. By tightening or loosening the nuts, a firm connection or convenient disassembly between the connecting rod and the first and second collars can be achieved, making the connecting rod an independent, quick-to-assemble and disassemble standard connector. This not only ensures the rigidity of power transmission, but also allows for easy removal of the connecting rod when it is necessary to maintain the drain pipe, lifting platform, or other related components, providing more operating space for internal maintenance of the equipment and further improving the overall maintainability and modularity of the transmission system.

[0018] 3. This wire cutting machine with a cleaning device, by setting up a guide bucket, an air inlet pipe and an air pipe connector, introduces a high-speed airflow from an external air source through the air inlet pipe. The airflow enters the plug cavity through the air pipe connector, and is then directionally sprayed into the drain pipe through the guide bucket. On the one hand, it creates a negative pressure in the drain pipe, enhancing the downward kinetic energy of the fluid. The air pressure difference significantly accelerates the flow of waste emulsified oil through the mesh bag, improving the liquid throughput efficiency. On the other hand, the airflow impact helps to agitate and break up any flocculent matter or fine debris that may adhere to the mesh bag, preventing mesh blockage. This strengthens the filtration and separation effect of the mesh bag and improves the smoothness and processing capacity of the entire waste liquid treatment system. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figures 1-8 A wire cutting machine with a cleaning device includes a base 1, a cutting unit, and a collecting unit. The cutting unit includes a housing 2, a control panel 3, and a wire cutter 4. The housing 2 is fixedly connected to the top of the base 1. The control panel 3 is located in the middle of one side of the housing 2. The wire cutter 4 is located on the side of the housing 2 near the collecting unit. The collecting unit includes a cutting box 5 and a protective frame 6. The cutting box 5 is fixedly connected to the top of the base 1, and the protective frame 6 is fixedly connected to the top of the cutting box 5. A clamping beam 11 is fixedly connected to the inner wall of the protective frame 6. The beam is slidably connected to a clamping mechanism. The base 1 is used to support the entire equipment. The machine box 2 in the cutting unit is fixed on the top of the base 1. The control panel 3 is located in the middle of its side for inputting operation commands. The clamping mechanism works with the clamping beam 11 to fix the workpiece. The clamping mechanism slides along the beam of the clamping beam 11 and can adapt to workpieces of different specifications. The wire cutter 4 is located on the side of the machine box 2 near the collection unit and performs the cutting action. The cutting debris and waste emulsified oil fall into the cutting box 5. The protective frame 6 is used to prevent debris from splashing around. A diversion hopper 10 is fixedly connected to the top inner wall of the cutting box 5. A guide ring 14 is fixedly connected to the bottom end of the diversion hopper 10. A drain pipe 17 is slidably connected inside the guide ring 14. A lifting drive unit is fixedly connected to the outer wall of the cutting box 5. The lifting part of the lifting drive unit is connected to the outer wall of the drain pipe 17. Evenly distributed positioning rods 22 are fixedly connected to the top of the drain pipe 17. A hanging rod 12 is fixedly connected to the bottom of the clamping beam 11. A plug 13 is fixedly connected to the bottom of the hanging rod 12. The top of the plug 13 is set as an arc surface. A positioning groove adapted to the positioning rod 22 is opened on the side of the plug 13. 23. The arc-shaped design at the top of the plug 13 facilitates the downward flow of waste emulsified oil. The positioning groove 23 on the outer wall of the plug 13, together with the positioning rod 22 at the top of the drain pipe 17, can seal the bottom of the diversion hopper 10. Processing debris and emulsified oil fall into the diversion hopper 10 of the cutting box 5. The lifting drive unit drives the drain pipe 17 to move downward, and the positioning rod 22 moves downward synchronously. The part of the positioning rod 22 that leaves the positioning groove 23 forms a grid. The debris and emulsified oil flow downward into the drain pipe 17 through the grid gap. Large volume of processing waste is blocked by the positioning rod 22 and remains in the diversion hopper 10, which is convenient for recycling. A mesh bag 19 is fixedly connected to the bottom of the drain pipe 17, and a waste liquid tank 21 is provided at the bottom of the cutting box 5. The waste liquid tank 21 is located below the mesh bag 19. The emulsified oil is filtered again through the mesh bag 19 to further separate the processing debris.

[0023] In this invention, the lifting drive unit includes a push rod motor 8, which is fixedly connected to the outer wall of the cutting box 5. A threaded seat 41 is fixedly connected to the telescopic part of the push rod motor 8. A connecting piece 27 is fixedly connected to the outer wall of the drain pipe 17. A first collar 28 is fixedly connected to the side of the connecting piece 27 away from the drain pipe 17. A push-pull groove 9 is provided on the side of the cutting box 5 near the push rod motor 8. A lifting platform 39 is slidably connected inside the push-pull groove 9. A second collar 40 is fixedly connected to one end of the lifting platform 39 inside the cutting box 5. A common connecting element is fixedly connected between the first collar 28 and the second collar 40. The lever 18 can drive the lifting platform 39 to rise or fall through the telescopic part of the push rod motor 8. When the lifting platform 39 moves, it slides along the inner wall of the push-pull groove 9. The lifting platform 39 can drive the drain pipe 17 to move synchronously through the connecting rod 18, thereby controlling the relative movement of the positioning rod 22 and the positioning groove 23, realizing the opening and closing control of the grille. The push-pull groove 9 plays an effective guiding and limiting role on the movement stroke of the lifting platform 39, ensuring the stability and reliability of the transmission process, avoiding the drain pipe 17 from swaying or getting stuck during the lifting process, so that the entire grille opening and closing action is precise, controllable and efficient in power transmission.

[0024] In this invention, a first bolt 37 is inserted into one end of the lifting platform 39 near the threaded seat 41. One end of the first bolt 37 is threaded into the inside of the threaded seat 41, and the other end of the first bolt 37 is fixedly connected to a knob 38. By rotating the first bolt 37 through the knob 38, the threaded part of the first bolt 37 is separated from the threaded seat 41, thereby realizing the separation between the threaded seat 41 and the lifting platform 39. Conversely, the threaded seat 41 and the lifting platform 39 can be locked together.

[0025] In this invention, a sliding seat 35 is fixedly connected to the bottom of the push rod motor 8, and a slot 36 is fixedly connected to the outer wall of the cutting box 5. The sliding seat 35 is slidably connected to the inside of the slot 36. One end of the slot 36 is set as an opening. After disconnecting the connection between the threaded seat 41 and the lifting platform 39, the push rod motor 8 is pushed in the direction of the opening of the slot 36, and the sliding seat 35 can slide out from the opening of the slot 36, thereby removing the push rod motor 8 from the side of the cutting box 5, which facilitates the installation and maintenance of the push rod motor 8.

[0026] In this invention, both ends of the connecting rod 18 are fixedly connected with second bolts 42. The two second bolts 42 are respectively inserted into the interior of the first collar 28 and the second collar 40, and the ends of the two second bolts 42 away from the connecting rod 18 are threaded with nuts 43. Both ends of the connecting rod 18 are fixedly connected with second bolts 42 and inserted into the interior of the first collar 28 and the second collar 40, respectively, and then locked by nuts 43. By tightening or loosening the nuts 43, a firm connection or convenient disassembly between the connecting rod 18 and the first collar 28 and the second collar 40 can be achieved, making the connecting rod 18 an independent, quick-to-assemble and disassemble standard connecting part. This not only ensures the rigidity of power transmission, but also allows the connecting rod 18 to be easily removed when it is necessary to maintain the drain pipe 17, the lifting platform 39 or other related components, providing more operating space for internal maintenance of the equipment and further improving the overall maintainability and modularity of the transmission system.

[0027] In this invention, two clamping mechanisms are provided. Each clamping mechanism includes a slider 29, a clamping plate 30, a screw 31, a threaded cylinder 32, a support plate 33, and a rotating handle 34. The slider 29 is slidably connected to the beam of the clamping beam 11. The support plate 33 is fixedly connected to the top of one side of the slider 29. The threaded cylinder 32 is fixedly connected to the top of the support plate 33. The screw 31 is threadedly connected to the inside of the threaded cylinder 32. The rotating handle 34 is fixedly connected to the top of the screw 31. The bottom end of the screw 31 extends to the bottom of the support plate 33. The clamping plate 30 is rotatably connected to the bottom end of the screw 31 and slidably connected to one side of the slider 29. Rotating the rotating handle 34 drives the screw 31 to descend, causing the clamping plate 30 to clamp the workpiece downwards. Rotating the rotating handle 34 in the opposite direction drives the screw 31 and the clamping plate 30 to rise, which can release the workpiece. Sliding the slider 29 along the beam of the clamping beam 11 can adjust the position of the two clamping plates 30 to adapt to the clamping of workpieces of different specifications.

[0028] In this invention, the bottom of the plug 13 is set as a cavity, and a guide bucket 24 is fixedly connected to the inner wall of the bottom of the cavity. The bottom end of the guide bucket 24 extends into the interior of the drain pipe 17. An air pipe connector 16 is inserted into the top of the plug 13, and an air inlet pipe 15 is fixedly connected to the top of the air pipe connector 16. A high-speed airflow from an external air source is introduced through the air inlet pipe 15. The airflow enters the cavity of the plug 13 through the air pipe connector 16, and is then directionally sprayed into the drain pipe 17 through the guide bucket 24. On the one hand, a negative pressure is formed in the drain pipe 17, which enhances the downward kinetic energy of the fluid. The air pressure difference significantly accelerates the speed at which the waste emulsified oil flows through the mesh bag 19, improving the liquid throughput efficiency. On the other hand, the airflow impact helps to agitate and break up any flocculent matter or fine debris that may adhere to the mesh bag 19, preventing the mesh from becoming clogged. This strengthens the filtration and separation effect of the mesh bag 19 and improves the smoothness and processing capacity of the entire waste liquid treatment system.

[0029] In this invention, a lifting cylinder 26 is fixedly connected to the outer wall of the top of the drain pipe 17. Guide grooves 25 are provided on both sides of the lifting cylinder 26, and protrusions are provided on the inner walls of both sides of the guide ring 14. The two guide grooves 25 are slidably engaged with the two protrusions respectively. The protrusions on the inner wall of the guide ring 14 are slidably engaged with the guide grooves 25, restricting the drain pipe 17 to move only in the vertical direction. The setting of the lifting cylinder 26 avoids the outer wall of the drain pipe 17 from directly contacting the guide ring 14, preventing the drain pipe 17 from leaking due to wear. At the same time, the precise sliding engagement of the protrusions and the guide grooves 25 provides accurate and stable bidirectional guidance for the lifting and lowering movement of the drain pipe 17, strictly restricting it to move only in the vertical direction, completely eliminating the radial sway or torsion that may occur during the lifting and lowering process, ensuring the accurate and reliable alignment and separation action between the positioning rod 22 and the positioning groove 23, thereby ensuring the consistency and stability of the grille opening and closing function.

[0030] In this invention, a threaded ring is fixedly connected to the top of the mesh bag 19. The threaded ring is threadedly engaged with the bottom inner wall of the drain pipe 17. The mesh bag 19 is installed at the bottom of the drain pipe 17 through the threaded ring. It can be installed and removed simply by rotating the mesh bag, which makes it convenient for operators to clean, inspect or replace the mesh bag 19 regularly, ensuring that the filtration function is continuously effective, thereby ensuring the long-term stable operation and convenient maintenance of the entire waste liquid treatment system.

[0031] In this invention, a maintenance door 7 is hinged to one side of the cutting box 5. A viewing window 44 is provided in the middle of the maintenance door 7. A handle 45 is fixedly connected to the outer side of the maintenance door 7. A limiting frame 20 is fixedly connected to the bottom inner wall of the cutting box 5. A waste liquid tank 21 is slidably connected to the inside of the limiting frame 20. The side of the limiting frame 20 near the maintenance door 7 is set as an opening. The waste emulsion separated by the net bag 19 is collected through the waste liquid tank 21. The viewing window 44 is used to observe the liquid level of the waste liquid tank 21 when the maintenance door 7 is closed. When the waste liquid tank 21 is full, the maintenance door 7 can be opened through the handle 45 to clean the waste liquid tank 21 and the net bag 19. The limiting frame 20 limits the placement position of the waste liquid tank 21, which facilitates the reset of the waste liquid tank 21 after each cleaning.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
