Description

Technical Field

[0001] This utility model relates to the technical field of cutting machine tools, specifically a precision medium-speed wire EDM machine tool that prevents clogging. Background Technology

[0002] Wire EDM machines, as high-precision CNC equipment, are widely used for processing complex-shaped metal workpieces. However, existing precision medium-speed wire EDM machines still have some defects in actual use. In particular, during the cutting process, the coolant needs to be continuously turned on. However, as the cutting operation progresses, the fine chips produced by the cutting will mix into the coolant, which not only clogs the cooling nozzles but also causes the coolant to be contaminated during oxidation, affecting its quality. This makes the coolant unusable, affecting production efficiency and cutting quality.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent No. CN213823752U, Publication Date: July 30, 2021) provides a wire EDM machine fluid filtration device, which solves the problems of poor filtration effect and low filtration efficiency of wire EDM coolant. The device includes a water tank, a turbine frame welded to one side of the water tank, a turbine bolted to the top of the turbine frame, a water pump screwed to one side of the top of the water tank, a cooling pipe sleeved at the water pump outlet, a retaining plate welded to the top of the water tank, a filter box held in place inside the retaining plate, a first filter layer and a second filter layer held in place inside the filter box, and a filter screen held in place at the top of the filter box. The first filter layer is made of sponge, and the second filter layer is made of cotton filter paper. This wire EDM coolant filtration device effectively removes solid particles through three layers of filtration, preventing blockage of the water pump and nozzles, preventing residue oxidation and contamination of the coolant, and simultaneously increasing the filtration speed by adding a turbine, thus saving time.

[0004] Existing technology uses two materials, sponge and cotton filter paper, for layered filtration. However, as the usage time increases, the filtration effect of sponge and filter paper may decrease, requiring frequent replacement of the filter layer. This increases the operating cost and maintenance workload of the equipment, affects the cutting efficiency of the equipment, and the turbine frame, water pump, and clamping plate components add to the complexity of the overall structure, making overall installation and maintenance inconvenient.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing anti-clogging precision wire EDM machines. Therefore, we propose that an anti-clogging precision wire EDM machine can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a precision wire EDM machine tool with anti-clogging technology, in order to solve the problem mentioned in the background art that the current market uses two materials, sponge and cotton filter paper, for layered filtration. However, as the usage time increases, the filtration effect of sponge and filter paper may decrease, so the filter layer needs to be replaced frequently, which increases the operating cost and maintenance workload of the equipment, affects the cutting efficiency of the equipment, and the turbine frame, water pump and clamping plate components increase the complexity of the overall structure, making the overall installation and maintenance inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a precision medium-speed wire EDM machine tool with anti-clogging features, comprising a frame, on which a take-up component and an auxiliary seat are mounted. An auxiliary shaft is provided inside the auxiliary seat. The take-up component and the auxiliary shaft facilitate the winding of the cutting wire to form a loop. A base is provided on the frame, and a protective cover for protection is installed on the base. A dual-axis motor is mounted on the base. A moving component is connected to the first output end of the dual-axis motor. A worktable is provided on the moving component. A rotating shaft is connected to the second output end of the dual-axis motor through a driving component. The rotating shaft is connected through the inside of the base. An eccentric wheel is provided on the outer side of the rotating shaft. A filter screen is connected inside the base through a vibrating component. After the eccentric wheel rotates, it contacts the filter screen.

[0008] Preferably, the auxiliary seat is provided with a first nozzle for conveying coolant, and a conveying pipe is installed at the bottom of the auxiliary seat. One end of the conveying pipe is connected to the inside of the auxiliary seat, and the other end of the conveying pipe is connected to the inside of the machine base. A liquid delivery tank inclined towards the conveying pipe is opened at the bottom of the auxiliary seat.

[0009] Preferably, a limiting cylinder is provided on the side end of the auxiliary seat, and a transmission pipe is connected through the limiting cylinder, with a lifting rod sealed and connected inside the transmission pipe.

[0010] Preferably, the lifting rod has a through groove, and after the lifting rod moves, the through groove is connected to the inside of the transmission pipe, and the input end of the transmission pipe is connected to an external coolant delivery pipe.

[0011] Preferably, the output end of the transmission pipe is connected to a second nozzle, which is distributed in a ring outside the cutting line.

[0012] Preferably, the top of the limiting cylinder and the top of the lifting rod are provided with magnetic block assemblies for controlling the lifting of the lifting rod.

[0013] Preferably, a first airbag is installed below the magnetic block assembly at the top of the lifting rod. After the lifting rod moves, the magnetic block assembly comes into contact with the first airbag, and the first airbag is connected to a second airbag through a pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In this anti-clogging precision wire EDM machine, the coolant falls into the machine base through a conveying groove and is filtered through a filter screen inside the machine base, facilitating the circulation of the coolant. The eccentric wheel on the outside of the rotating shaft rotates and contacts the filter screen, causing the filter screen to vibrate inside the machine base via a vibrating component, effectively preventing filter screen clogging, ensuring the coolant filtration effect, maintaining the normal operation of the machine tool, reducing the efficiency reduction caused by frequent maintenance, and having a simple overall structure that is convenient for installation and maintenance. The specific details are as follows: The coolant is filtered through an internal filter screen, which enables coolant recovery and preliminary filtration, facilitating coolant recycling. The filter screen vibrates inside the base via a vibrating component, effectively preventing filter screen clogging and reducing efficiency loss caused by frequent maintenance.

[0016] Coolant is sprayed out through the first nozzle, which cools the cutting wire conveyed inside the auxiliary seat, improving the working performance and service life of the cutting wire. The cleaned coolant is then transported to the machine base through the delivery pipe, where it is filtered by the filter screen inside the machine base.

[0017] The inclined inlet channel at the bottom of the auxiliary seat facilitates the transfer of coolant through the delivery pipe, improving the coolant delivery effect. The coolant is sprayed out through the second nozzle, which is arranged in a ring outside the cutting line, enabling all-round cooling and cleaning of the cutting line, reducing wear caused by high temperature and impurities, and effectively extending the service life of the cutting line.

[0018] The magnetic block assembly set at the top of the limiting cylinder and the top of the lifting rod facilitates the generation of magnetic force for operation and use, and connects the through groove of the lifting rod with the transmission pipe to facilitate the delivery of coolant. The overall operation is simple and easy to control precisely, which improves the overall level of automation.

[0019] The baffle opens, blocking the coolant sprayed from the second nozzle. This not only reduces coolant splashing and resource waste, but also concentrates the coolant to cool the cutting line, improving coolant efficiency. Attached Figure Description

[0022] 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.

[0023] Example 1: In this example, the filter screen 13 is vibrated inside the base 5 by the vibrating component 14, effectively preventing the filter screen 13 from clogging and ensuring the cooling fluid filtration effect. Figures 1-3The technical solution shown includes a frame 1, on which a winding component 2 and an auxiliary seat 3 are mounted. An auxiliary shaft 4 is located inside the auxiliary seat 3. The winding component 2 and the auxiliary shaft 4 facilitate the formation of a loop around the cutting wire. A base 5 is mounted on the frame 1, and a protective cover 6 is mounted on the base 5. A dual-axis motor 7 is mounted on the base 5. A moving component 8 is connected to the first output end of the dual-axis motor 7. A worktable 9 is mounted on the moving component 8. The second output end of the dual-axis motor 7 is connected to a rotating shaft 11 via a drive component 10. The rotating shaft 11 is internally connected to the base 5. An eccentric wheel 12 is provided on the outer side. A filter screen 13 is connected inside the machine base 5 through a vibrating component 14. After the eccentric wheel 12 rotates, it contacts the filter screen 13. The frame 1 facilitates the movement of the device to the required position and can flexibly adapt to different processing site requirements. The cutting wire is installed through the winding component 2 and the auxiliary shaft 4 on the auxiliary seat 3. The workpiece to be cut is placed on the worktable 9. The dual-axis motor 7 on the machine base 5 is turned on. The output end of the dual-axis motor 7 drives the moving component 8 to move. The moving component 8 in this application is a moving structure with a screw and a guide rod, which facilitates the operation of the upper part. The platform 9 moves and cuts the workpiece, greatly improving overall cutting efficiency. During cutting, coolant is introduced, and the protective cover 6 on the machine base 5 provides protection. The cover effectively prevents coolant and chips from splashing, ensuring operator safety and preventing environmental contamination. The coolant flows into the machine base 5 through a conveyor trough and is filtered by the internal filter 13, achieving coolant recovery and preliminary filtration. This facilitates coolant recycling, reduces production costs, and enables dual-axis electric... When the machine 7 is in use, its second output end drives the rotating shaft 11 to rotate through the drive component 10. The drive component 10 of this application is a transmission structure with a pulley and a belt, which facilitates the drive component 10 to drive the rotating shaft 11 to rotate inside the machine base 5. At this time, the eccentric wheel 12 on the outside of the rotating shaft 11 rotates and contacts the filter screen 13, so that the filter screen 13 vibrates inside the machine base 5 through the vibrating component 14, which effectively prevents the filter screen 13 from clogging, ensures the filtration effect of the coolant, maintains the normal operation of the machine tool, and reduces the problem of efficiency reduction caused by frequent maintenance. The overall structure is simple and convenient for installation and maintenance. Example 2: In this example, coolant is sprayed out through the first nozzle 15, which cools the cutting wire conveyed inside the auxiliary seat 3. Specifically, as follows... Figure 2 and Figures 4-8As shown, the auxiliary base 3 is equipped with a first nozzle 15 for conveying coolant. A conveying pipe 16 is installed at the bottom of the auxiliary base 3. One end of the conveying pipe 16 is connected to the inside of the auxiliary base 3, and the other end is connected to the inside of the base 5. A liquid delivery groove inclined towards the conveying pipe 16 is opened at the bottom of the auxiliary base 3. A limiting cylinder 17 is provided on the side of the auxiliary base 3. A transmission pipe 18 is connected through the limiting cylinder 17. A lifting rod 19 is sealed and connected through the inside of the transmission pipe 18. A through groove 20 is opened on the lifting rod 19. After the lifting rod 19 moves, the through groove 20 is connected to the inside of the transmission pipe 18. The input end of the transmission pipe 18 is connected to an external coolant conveying pipe. The output end of the transmission pipe 18 is connected to a second nozzle 21. The second nozzle 21 is distributed in a ring outside the cutting line, and introduces coolant into the pipe connected to the first nozzle 15, facilitating the flow of coolant through the first nozzle 15. The coolant sprays out from the auxiliary seat 3, cooling the cutting wire conveyed inside. The sprayed coolant also helps clean residual impurities on the cutting wire, improving its performance and lifespan. The cleaned coolant is then transported through the conveying pipe 16 to the machine base 5 for filtration by the internal filter screen 13. An inclined liquid delivery groove at the bottom of the auxiliary seat 3 facilitates coolant transport through the conveying pipe 16, improving the coolant delivery efficiency. The coolant is connected to the transmission pipe 18 inside the limiting cylinder 17 and then transported through the through-slot 20 inside the lifting rod 19, allowing it to be sprayed out through the second nozzle 21 for cleaning and cooling the conveyed wire. The second nozzle 21 is arranged in a ring around the outside of the cutting wire, providing all-around cooling and cleaning, reducing wear caused by high temperatures and impurities, and effectively extending the cutting wire's lifespan. Example 3: In this example, the coolant sprayed from the second nozzle 21 is blocked by the baffle 26, which not only reduces the problem of coolant splashing and resource waste, but also concentrates the coolant to cool the cutting line, improving the efficiency of coolant use. Specifically, as shown below... Figures 6-9As shown, a magnetic block assembly 22 for controlling the lifting rod 19 is provided at the top of the limiting cylinder 17 and the top of the lifting rod 19. A first airbag 23 is installed below the magnetic block assembly 22 at the top of the lifting rod 19. After the lifting rod 19 moves, the magnetic block assembly 22 contacts the first airbag 23. The first airbag 23 is connected to a second airbag 24 through a pipe. A baffle 26 is provided on the side of the second nozzle 21. The baffle 26 is arranged in a ring. A rotating rod 25 is connected through the baffle 26. A torsion spring 27 is provided on the outside of the rotating rod 25. The second airbag 24 is provided on the side of the baffle 26. The magnetic block assembly 22 at the top of the limiting cylinder 17 and the top of the lifting rod 19 facilitates the generation of magnetic force for operation and use. When the magnetic blocks at the top of the limiting cylinder 17 and the top of the lifting rod 19 have different magnetic properties, the lifting rod 19 moves upward. When the two magnetic blocks have the same magnetic properties, the magnetic block assembly 22 drives the lifting rod 19 to move downward, so that the through groove 20 of the lifting rod 19 connects with the transmission pipe. The 18-way connection facilitates coolant delivery, and the overall operation is simple, convenient, and precise, improving the overall automation level. At this time, the magnetic block assembly 22 compresses the first airbag 23, causing the gas inside the first airbag 23 to be transported to the second airbag 24 through the pipe. This allows the second airbag 24 to contact the baffle 26, causing the baffle 26 to rotate in cooperation with the rotating rod 25, facilitating the opening of the baffle 26. This prevents the coolant sprayed from the second nozzle 21 from being blocked by the baffle 26, reducing coolant splashing and resource waste, and concentrating the coolant to cool the cutting line, improving coolant utilization efficiency. At this time, the torsion spring 27 on the outside of the rotating rod 25 deforms. When the lifting rod 19 returns to its initial position, the baffle 26 rotates through the torsion spring 27 on the outside of the rotating rod 25. The overall structure is ingenious and stable in operation, facilitating maintenance. The contents not described in detail in this specification are prior art known to those skilled in the art.

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.
