TECHNICAL FIELD
[0001] The present application relates to the technical field of metal cutting, in particular to a cutting device for preparing beryllium window sheet. BACKGROUND
[0002] The beryllium window sheet is a high-quality X-ray diffraction instrument accessory used as a separation window between the sample and the X-ray in XRD experiments, which is made of high-purity beryllium material and has excellent corrosion resistance and high-temperature stability.
[0003] The beryllium window sheet is often processed by a wire electrical discharge machine. The high-speed wire electrical discharge machine mainly comprises a rack, a workbench, a wire storage cylinder, a water spray plate, a pulse power supply and a cutting fluid conveying device. The workbench is fixedly installed on the rack and slides by a servo motor, a ball screw and a nut pair. The wire storage cylinder, the water spray plate and the pulse power supply are fixedly installed on the workbench. The water spray plate is symmetrically installed on the workbench and is provided with a clamp between the water spray plates for fixing the beryllium plate. The clamp is fixedly installed on the rack. The water spray plate is provided with a wire passing hole and a liquid injection port. The liquid injection port is connected with the cutting fluid conveying device. The electrode wire is fixedly installed on the wire storage cylinder through the wire passing hole. The electrode wire is in contact with the pulse power supply during installation. When the beryllium plate needs to be cut, the pulse power supply is started, the electrode wire is electrified, and the workbench drives the water spray plate to move, thereby driving the electrode wire to cut the beryllium plate. The cutting fluid is sprayed from the water spray plate to cool the beryllium plate, and at the same time, the cutting fluid impacts and cleans the debris adhered to the electrode wire. The cutting fluid ensures the safety of the working process by its own insulation property.
[0004] However, the cutting fluid slides along the electrode wire after being sprayed from the water spray plate. The flow speed of the cutting fluid gradually decreases and the flow area is not concentrated enough during the sliding process, thereby causing the impact force of the cutting fluid to be insufficient when the cutting fluid flows to the beryllium plate along the electrode wire. This results in insufficient cleaning effect of the debris, which causes the debris to accumulate in the cutting gap or adhere to the electrode wire, thereby causing the electrode wire to wear out and increasing the risk of wire breakage. In addition, the cutting fluid cannot be unified with the cutting speed. When the cutting speed increases, the debris generated by cutting increases, and the insufficient cleaning effect caused by the unchanged flow of the cutting fluid.
[0005] In view of the above, the present application provides a cutting device for preparing beryllium window sheet. SUMMARY
[0006] The present application aims to provide a cutting device for preparing beryllium window sheet to solve the problem of insufficient cleaning effect of the cutting fluid leading to debris accumulation and affecting the normal use of the electrode wire as described in the background.
[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A cutting device for preparing beryllium window plates includes: an electrical discharge wire cutting machine, a water spray plate, a speed sensor, a drive motor, a flow guiding assembly, a flow guiding plate, a flow boosting assembly, and a flow boosting plate. The electrical discharge wire cutting machine is symmetrically equipped with water spray plates, which are used to cool the workpiece and clean up debris generated during cutting. A speed sensor is fixedly installed on the water spray plate to monitor the cutting speed. The water spray plate has wire-threading holes for installing electrode wires, and the water spray plate has a connection point communicating with the wire-threading holes. The cutting fluid channel has an inlet and an outlet, which is used to transport the cutting fluid. The cutting fluid enters through the inlet and is sprayed out in a cone shape from the outlet, causing it to fall onto the electrode wire and slide down onto the beryllium plate for cooling and cleaning. An adjustment cavity connected to the cutting fluid channel is provided on the upper spray plate, and an installation groove is provided at the front end of the upper spray plate. A drive motor is fixedly installed in the installation groove, which is located away from the cutting fluid channel, thus reducing the installation space. Regarding the installation of the drive motor, a flow guiding assembly is provided below the drive motor. The flow guiding assembly is rotatably mounted with the water spray plate. A ring array of flow guiding plates is arranged within the flow guiding assembly. The flow guiding plates are coaxially mounted with the wire threading hole. When the wire EDM machine is working, the drive motor drives the flow guiding plates through the flow guiding assembly to extend and gather the cutting fluid, thereby increasing the cutting fluid flow rate. During operation, the cutting fluid is sprayed out from the cutting fluid channel and slides down along the electrode wire. During the sliding process, the cutting fluid has a large flow range, and at this time, the cutting fluid is only subject to gravity, thus leading to... Insufficient impact force results in incomplete cleaning of debris within the cutting gap. In this case, the drive motor drives the guide plate to slide out through the guide assembly. The bottom end of the guide plate contacts the beryllium plate. When the cutting fluid is sprayed out, the guide plate gathers the cutting fluid through its own structure, allowing the cutting fluid to flow in a concentrated manner. At the same time, the cutting fluid is pressurized to achieve a higher flow rate, thereby generating a stronger impact force to ensure the efficiency of debris cleaning and thus ensure the service life of the electrode wire. Then, the wire storage drum rotates, which in turn drives the electrode wire to slide back and forth to cut the beryllium plate. A flow-boosting component is provided on one side of the flow-guiding component, located on the water spray plate. A flow-boosting plate is positioned above the flow-guiding component and located within the regulating cavity. When the wire EDM machine is operating, the speed sensor controls the drive motor speed based on the cutting speed. The drive motor controls the flow-boosting component through the flow-guiding component. The flow-boosting component drives the flow-boosting plate to reciprocate, increasing the cutting fluid flow rate. When processing beryllium window plates, the production efficiency varies depending on production requirements; therefore, the cutting speed of the wire EDM machine varies to meet different production needs. To meet the demand, when the cutting speed of the wire EDM machine increases, the pulse current is increased simultaneously, thereby increasing the cutting efficiency of the wire EDM machine on the beryllium plate. When the cutting speed of the wire EDM machine increases, the amount of debris generated during electrode wire cutting also increases simultaneously. At this time, the flow booster component drives the flow booster plate to reciprocate, thereby increasing the flow rate of the cutting fluid, ensuring the efficiency of the cutting fluid in cleaning debris. At the same time, the increased flow rate of the cutting fluid enhances the heat exchange efficiency between the cutting fluid and the beryllium plate, thereby enhancing the cooling effect of the cutting fluid on the beryllium plate and avoiding insufficient cooling efficiency of the beryllium plate when the cutting speed increases.
[0008] Preferably, the flow guiding assembly includes a drive wheel, a double-sided gear ring, a fixed rod, a driven wheel, a drive rod, and a cleaning wheel; the drive wheel is fixedly installed with a drive motor, and the drive wheel is rotatably mounted on the spray plate. A double-sided gear ring is provided on one side of the drive wheel. When processing the beryllium plate, the drive motor is first started, and the drive motor rotates forward, thereby driving the drive wheel to rotate synchronously. The drive wheel meshes with the outer teeth of the double-sided gear ring, thereby driving the double-sided gear ring to rotate. The double-sided gear ring can be considered as an outer gear ring with an inner gear ring installed inside; a fixed rod is provided below the double-sided gear ring; the fixed rod is fixedly installed with the spray plate, and the fixed rod has… A limiting groove is provided, and the fixing rod plays a fixed limiting role, thereby ensuring the stable operation of the mechanism. A driven wheel is linearly arrayed on the inner circumference of the double-sided gear ring, and a drive rod is fixedly installed inside the driven wheel. A drive block is provided on the drive rod, and a guide plate is slidably installed on the drive rod. The guide plate is slidably installed inside the fixing rod, and a drive groove that mates with the drive block is provided on the guide plate. A limiting block that mates with the limiting groove is also provided on the guide plate. When the double-sided gear ring rotates, the teeth on the inner side of the double-sided gear ring mesh with the driven wheel, thereby driving multiple driven wheels to rotate synchronously. The driven wheels drive the drive rod to rotate synchronously, and the rotation of the drive rod... The drive block compresses the drive groove on the guide plate. Since the limiting block on the guide plate is slidably installed in the limiting groove on the fixed rod, the cooperation between the limiting groove and the limiting block restricts the degree of freedom of the guide plate, allowing it to slide only vertically. Therefore, under the action of the drive rod, the guide plate slides vertically downwards and extends to contact the beryllium plate. The inner sides of the multiple guide plates form a frustum-shaped structure, which guides and converges the splashed cutting fluid, ensuring the flow rate of the cutting fluid. Simultaneously, the flow area of the cutting fluid is gradually reduced during its flow, thereby increasing the pressure on the cutting fluid. The strong flow of cutting fluid enhances its impact force and improves the efficiency of chip removal. A cleaning wheel is rotatably mounted on the lower end of the frustum-shaped structure. The cleaning wheel is coaxially mounted with the wire threading hole. When installing the electrode wire, the electrode wire must pass through the cleaning wheel to complete the installation because the cleaning wheel and the wire threading hole are coaxially mounted. The guide plate drives the cleaning wheel to slide vertically downward. When the wire EDM machine is working, the cleaning wheel remains fixed while the electrode wire slides up and down, causing the cleaning wheel and the electrode plate to slide relative to each other. The cleaning wheel removes the chips on the electrode wire, preventing chips from adhering to the surface of the electrode wire and affecting the cutting efficiency.
[0009] Preferably, the driven wheel has a circular array of telescopic grooves. The telescopic grooves are fixedly installed at one end of the telescopic spring, and the other end of the telescopic spring is fixedly connected to the telescopic wheel teeth. The telescopic wheel teeth are slidably installed in the telescopic grooves. After the guide plate is fully extended, the drive block of the drive rod moves to the top of the drive groove of the guide plate. Under the action of the fixed rod, the guide plate can only slide vertically and cannot rotate. This causes the guide plate to obstruct the rotation of the drive rod through the drive groove, keeping the drive rod fixed and thus driving the driven wheel to remain fixed. At this time, the double-sided gear ring still rotates. The inner teeth of the double-sided gear ring mesh with the telescopic wheel teeth. With the driven wheel fixed, the telescopic wheel teeth, under the action of the double-sided gear ring, squeeze the telescopic spring into the telescopic groove, thereby ensuring the stability of the rotation of the double-sided gear ring.
[0010] Preferably, a drainage surface is provided above the cleaning wheel, and an insulating gasket is provided below the drainage surface. The drainage surface guides the cutting fluid, preventing the cutting fluid from coming into perpendicular contact with the cleaning wheel, which would obstruct the flow of the cutting fluid and reduce its flow rate. At the same time, the insulating gasket in the middle isolates the current emitted by the pulse generator, thereby ensuring the safety of cutting.
[0011] Preferably, the guide plate is provided with a spiral flow channel, which guides the flow of the cutting fluid, causing the cutting fluid to flow in a spiral shape during the flow process, thereby increasing the flow speed of the cutting fluid, and thus increasing the impact force of the cutting fluid, ensuring the cleaning effect of debris.
[0012] Preferably, the flow-enhancing component includes a drive wheel, a rotating shaft, flow-enhancing blades, a crank-rocker mechanism, a slider, and a reciprocating spring; the drive wheel is located on one side of the double-sided gear ring and is symmetrically installed with the drive wheel; the drive wheel is rotatably mounted on the bottom of the spray plate. After the guide plate slides out, cutting begins. A speed sensor monitors the cutting speed and controls the rotation speed of the drive motor according to the cutting speed. The drive motor continues to rotate, which in turn drives the double-sided gear ring to rotate through the drive wheel. The outer teeth of the double-sided gear ring mesh with the teeth of the drive wheel, causing the drive wheel to rotate, while the driven wheel remains fixed under the action of the telescopic teeth; a rotating shaft is fixedly mounted on the drive wheel; the top of the rotating shaft is located in the adjustment cavity, and a flow-enhancing blade is fixedly mounted on the middle of the rotating shaft. When the drive wheel rotates, it drives the rotating shaft to rotate synchronously, and the rotating shaft drives the flow-enhancing blade fixedly mounted on it to rotate. The flow-enhancing blade adjusts its own rotation speed according to the cutting speed. As the cutting speed increases, the rotation speed of the flow-enhancing blades increases, thereby increasing the delivery efficiency of the cutting fluid and the flow rate. A crank-rocker mechanism is connected to the top of the rotating shaft. A slider is mounted on the crank-rocker mechanism and slidably installed within the adjustment cavity. A squeezing groove is provided at the bottom of the slider, and a flow-enhancing plate is located below the slider. The flow-enhancing plate is situated within the cutting fluid flow channel and has a squeezing groove that cooperates with the slider. The flow-enhancing plate and the adjustment cavity are connected by a reciprocating spring. When the rotating shaft rotates, it simultaneously drives the crank-rocker mechanism, which in turn drives the slider to reciprocate. As the slider slides along the direction of the flow-enhancing plate, the slider pushes the flow-enhancing plate vertically downwards through the squeezing groove. The flow-enhancing plate reduces the volume of the cutting fluid flow channel, thereby pressurizing the cutting fluid and increasing its flow rate. When the slider returns to its original position away from the flow-enhancing plate, the flow-enhancing plate returns to its original position under the action of the reciprocating spring.
[0013] Preferably, the crank-rocker mechanism includes a crank and a rocker; one end of the crank is fixedly installed to the rotating shaft, the other end of the crank is rotatably connected to the rocker, and the rocker is rotatably connected to the slider; the slider is eccentrically installed to the crank, the crank is fixedly connected to the rotating shaft, and rotates synchronously with the rotating shaft, thereby causing the crank to drive the rocker connected to it to swing, and the rocker pulls the slider to slide horizontally. The eccentric installation of the slider and the crank results in the crank-slider structure having a quick-return characteristic, so that when the slider slides along the direction of the flow booster plate, it advances quickly and returns slowly, thus giving the flow booster plate a faster speed when sliding downwards, ensuring the extrusion pressure on the cutting fluid. The flow booster plate returns to its original position relatively slowly, avoiding disturbance of the cutting fluid in the flow channel.
[0014] Preferably, the flow booster plate is provided with a pressure boosting protrusion, which corresponds to the outlet of the cutting fluid flow channel. The pressure boosting protrusion is used to enhance the squeezing force of the flow booster plate on the cutting fluid, thereby ensuring the flow velocity of the cutting fluid and ensuring a stable increase in the flow rate of the cutting fluid. The pressure boosting protrusion corresponds to the outlet, so that there is a pressure boosting protrusion above each outlet, thereby making the cutting fluid flowing out of the outlet have a larger initial velocity, thus ensuring the flow velocity of the cutting fluid, avoiding cutting fluid splashing, and ensuring the stability of the cutting fluid spray.
[0015] Preferably, the pressure boosting bump has a hemispherical structure. The hemispherical structure reduces the resistance between the pressure boosting bump and the cutting fluid, thereby ensuring the stability of the flow booster plate sliding. At the same time, the hemispherical structure can generate uniform extrusion force, ensuring the stability of the cutting fluid flow.
[0016] Preferably, the cutting fluid flow channel is provided with a flow divider block, which corresponds to the flow booster blade. The flow divider block has a through hole in the middle. The flow divider block guides the flow direction of the cutting fluid through its shape, so that the cutting fluid flows evenly from both sides, thereby quickly filling the cutting fluid flow channel and ensuring the stability of the cutting fluid delivery. When the flow booster blade rotates, it agitates the cutting fluid to flow quickly. The cutting fluid flow comes into contact with the flow divider block and flows evenly from both sides of the flow divider block, quickly filling the cutting fluid flow channel. The through hole in the middle of the flow divider block is used for the flow of cutting fluid. When the flow booster plate slides vertically downward to increase pressure, the flow divider block reduces the obstruction effect on the cutting fluid through the through hole, thereby ensuring the stable outflow of cutting fluid.
[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. A cutting device for preparing beryllium window plates. The present invention achieves the unification of cutting speed and cutting fluid flow rate and velocity through the cooperation of flow guiding component and flow boosting component, thereby ensuring the cleaning effect of debris and the cooling effect of beryllium plate, ensuring the working life of electrode wire, and improving processing efficiency and quality.
[0018] 2. A cutting device for preparing beryllium window plates. The present invention cleans the surface of the electrode wire by means of a flow guiding component, so as to avoid the problem of the electrode wire overheating, electrode wire service life and processing quality being reduced due to the adhesion of debris on the surface of the electrode wire.

Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Beryllium window plates are commonly processed using wire EDM machines. A high-speed wire EDM machine mainly consists of a frame, worktable, wire spool, water spray plate, pulse power supply, and cutting fluid delivery system. The worktable is fixedly mounted on the frame and slides via a servo motor and ball screw nut assembly. The wire spool, water spray plate, and pulse power supply are fixedly mounted on the worktable. The water spray plates are symmetrically mounted on the worktable, with clamps between them for securing the beryllium plates. The clamps are fixedly mounted to the frame. The water spray plates have wire insertion holes and spray nozzles, which are connected to the cutting fluid delivery system. The electrode wire is fixed to the wire storage drum at both ends through the wire threading hole. During installation, the electrode wire is in contact with the pulse power supply. When the beryllium plate needs to be cut, the pulse power supply is activated, the electrode wire is energized, the worktable drives the water spray plate to move, and thus the electrode wire cuts the beryllium plate. The cutting fluid is sprayed from the water spray plate to cool the beryllium plate. At the same time, it impacts and cleans the debris adhering to the electrode wire. The cutting fluid ensures the safety of the working process through its own insulation properties. In addition, the EDM machine is also equipped with a cutting fluid recovery system to recycle the cutting fluid.
[0024] However, as the cutting fluid is sprayed from the spray plate and slides down the electrode wire, its flow rate gradually decreases and the flow area becomes less concentrated. Consequently, when the cutting fluid flows down the electrode wire to the beryllium plate, the impact force of the cutting fluid is insufficient, resulting in inadequate chip removal. This causes chips to accumulate in the cutting gap or adhere to the electrode wire, leading to increased electrode wire wear and a higher risk of wire breakage. Furthermore, the cutting fluid flow rate cannot be synchronized with the cutting speed. When the cutting speed increases, more chips are generated, but the cutting fluid flow rate remains constant, resulting in insufficient cleaning and further exacerbating electrode wire wear, increasing the risk of wire breakage.
[0025] The present invention provides a technical solution: like Figures 1 to 15As shown, a cutting device for preparing beryllium window plates includes: an electrical discharge wire cutting machine 1, a water spray plate 2, a speed sensor 3, a drive motor 4, a flow guiding component 5, a flow guiding plate 6, a flow boosting component 7, and a flow boosting plate 8; the electrical discharge wire cutting machine 1 is symmetrically equipped with water spray plates 2; the speed sensor 3 is fixedly installed on the water spray plate 2; the water spray plate 2 has a wire-passing hole 21, and a cutting fluid flow channel 22 communicating with the wire-passing hole 21, the cutting fluid flow channel 22 having an inlet and an outlet; the upper water spray plate 2 has an adjustment cavity 23 communicating with the cutting fluid flow channel 22, and the front end of the upper water spray plate 2 has an installation groove 24; the drive motor 4 is fixedly installed in the installation groove 24, and a flow guiding component is provided below the drive motor 4. 5. The flow guiding component 5 is rotatably mounted with the water spray plate 2. The flow guiding component 5 has a ring array of flow guiding plates 6. The flow guiding plates 6 are coaxially mounted with the wire threading hole 21. When the wire EDM machine 1 is working, the drive motor 4 drives the flow guiding plate 6 to extend and gather the cutting fluid through the flow guiding component 5, thereby increasing the cutting fluid flow rate. A flow boosting component 7 is provided on one side of the flow guiding component 5. The flow boosting component 7 is located on the water spray plate 2. A flow boosting plate 8 is provided above the flow boosting component 7. The flow boosting plate 8 is located in the adjustment cavity 23. When the wire EDM machine 1 is working, the speed sensor 3 controls the speed of the drive motor 4 according to the cutting speed. The drive motor 4 controls the flow boosting component 7 through the flow guiding component 5. The flow boosting component 7 drives the flow boosting plate 8 to reciprocate to increase the cutting fluid flow rate.
[0026] Specifically, the wire EDM machine 1 is symmetrically equipped with water spray plates 2, which are used to cool the workpiece and clean up the debris generated during cutting. A speed sensor 3 is fixedly installed on the water spray plates 2 to monitor the cutting speed. The water spray plates 2 have wire threading holes 21 for installing the electrode wire, and a cutting fluid channel 22 communicating with the wire threading holes 21. The cutting fluid channel 22 has an inlet and an outlet, and is used to achieve… The cutting fluid is supplied through an inlet and sprayed out in a cone shape from an outlet, landing on the electrode wire and then sliding down onto the beryllium plate for cooling and cleaning. An adjustment chamber 23 connected to the cutting fluid flow channel 22 is provided on the upper spray plate 2, and an installation groove 24 is provided at the front end of the upper spray plate 2. A drive motor 4 is fixedly installed in the installation groove 24. The installation groove 24 is located away from the cutting fluid flow channel 22, thus reducing the installation space and facilitating the installation and operation of the drive motor 4. Below the drive motor 4 is a flow guide assembly 5, which is rotatably mounted with the water spray plate 2. The flow guide assembly 5 contains a ring array of flow guide plates 6, which are coaxially mounted with the wire threading hole 21. When the wire EDM machine 1 is working, the drive motor 4 drives the flow guide plates 6 through the flow guide assembly 5 to extend and gather the cutting fluid, thereby increasing the cutting fluid flow rate. During operation, the cutting fluid is sprayed out from the cutting fluid channel 22 and slides down along the electrode wire. During the sliding process, the cutting fluid has a large flow range, and at this time, the cutting fluid is only subject to gravity. The slow flow rate results in insufficient impact force, leading to incomplete cleaning of debris within the cutting gap. In this case, the drive motor 4 drives the guide plate 6 to slide out through the guide assembly 5. The bottom end of the guide plate 6 contacts the beryllium plate. When the cutting fluid is sprayed out, the guide plate 6 gathers the cutting fluid through its own structure, allowing the cutting fluid to flow in a concentrated manner. At the same time, the cutting fluid is pressurized to achieve a higher flow rate, thereby generating a stronger impact force, ensuring efficient cleaning of debris, and thus ensuring the service life of the electrode wire.
[0027] A flow booster component 7 is provided on one side of the flow guide component 5. The flow booster component 7 is located on the water spray plate 2, and a flow booster plate 8 is provided above the flow booster component 7. The flow booster plate 8 is located in the adjustment cavity 23. When the wire EDM machine 1 is working, the speed sensor 3 controls the speed of the drive motor 4 according to the cutting speed. The drive motor 4 controls the flow booster component 7 through the flow guide component 5. The flow booster component 7 drives the flow booster plate 8 to reciprocate to increase the flow of cutting fluid. When processing beryllium window plates, the production efficiency of beryllium window plates varies according to different production needs. Therefore, the cutting speed of the wire EDM machine 1 varies to meet different production needs. When the cutting speed of the wire EDM machine 1 increases, the pulse current is increased synchronously, thereby making the wire EDM machine 1 more efficient at cutting beryllium window plates. The cutting efficiency of the plate increases. When the cutting speed of the wire EDM machine 1 increases, the debris generated during electrode wire cutting also increases simultaneously. At this time, the flow booster component 7 drives the flow booster plate 8 to reciprocate, thereby increasing the flow rate of the cutting fluid and ensuring the efficiency of the cutting fluid in cleaning debris. At the same time, the increased flow rate of the cutting fluid enhances the heat exchange efficiency between the cutting fluid and the beryllium plate, thereby enhancing the cooling effect of the cutting fluid on the beryllium plate and avoiding insufficient cooling efficiency of the beryllium plate when the cutting speed increases. Meanwhile, as the flow rate of the cutting fluid increases, with the volume of the guide plate 6 remaining unchanged, the pressure on the cutting fluid per unit area further increases, thereby further increasing the flow rate of the cutting fluid and enhancing the impact force of the cutting fluid, ensuring the efficiency of debris cleaning.
[0028] In this embodiment, the flow guiding component 5 includes a driving wheel 51, a double-sided gear ring 52, a fixed rod 53, a driven wheel 54, a drive rod 55, and a cleaning wheel 56; the driving wheel 51 is fixedly installed with the drive motor 4, and the driving wheel 51 is rotatably installed on the spray plate 2. A double-sided gear ring 52 is provided on one side of the driving wheel 51; a fixed rod 53 is provided below the double-sided gear ring 52; the fixed rod 53 is fixedly installed with the spray plate 2, and a limit groove 531 is provided on the fixed rod 53; driven wheels 54 are linearly arrayed on the inner circumference of the double-sided gear ring 52; A drive rod 55 is fixedly installed inside the driven wheel 54; a drive block 551 is provided on the drive rod 55, and a guide plate 6 is slidably installed on the drive rod 55; the guide plate 6 is slidably installed inside the fixed rod 53, and a drive groove 61 that cooperates with the drive block 551 is opened on the guide plate 6; a limit block 62 that cooperates with the limit groove 531 is provided on the guide plate 6; the inner sides of the multiple guide plates 6 form a frustum-shaped structure 63; a cleaning wheel 56 is rotatably installed at the lower end of the frustum-shaped structure 63; the cleaning wheel 56 is coaxially installed with the wire threading hole 21.
[0029] Specifically, the drive wheel 51 is fixedly installed with the drive motor 4. The drive wheel 51 is rotatably mounted on the spray plate 2. A double-sided gear ring 52 is provided on one side of the drive wheel 51. When processing the beryllium plate, the drive motor 4 is started first. The drive motor 4 rotates forward, thereby driving the drive wheel 51 to rotate synchronously. The drive wheel 51 meshes with the outer gear teeth of the double-sided gear ring 52, thereby driving the double-sided gear ring 52 to rotate. The double-sided gear ring 52 can be regarded as an outer gear ring with an inner gear ring installed inside. A fixing rod 53 is provided below the double-sided gear ring 52. The fixing rod 53 is fixedly installed with the spray plate 2. A limit groove 531 is provided on the fixing rod 53. The fixing rod 53 plays a fixed and limiting role, thereby ensuring the stable operation of the mechanism. A driven wheel 54 is linearly arrayed on the inner circumference of the double-sided gear ring 52. A drive rod 55 is fixedly installed in the driven wheel 54. A drive block 551 is provided on the drive rod 55. A guide plate 6 is slidably mounted on the fixed rod 53. The guide plate 6 is slidably mounted inside the fixed rod 53. The guide plate 6 has a drive groove 61 that cooperates with the drive block 551. The guide plate 6 has a limit block 62 that cooperates with the limit groove 531. When the double-sided gear ring 52 rotates, the gear teeth on the inner side of the double-sided gear ring 52 mesh with the driven wheel 54, thereby driving multiple driven wheels 54 to rotate synchronously. The driven wheels 54 drive the drive rod 55 to rotate synchronously. When the drive rod 55 rotates, it squeezes the drive groove 61 on the guide plate 6 through the drive block 551. Since the limit block 62 on the guide plate 6 is slidably mounted in the limit groove 531 on the fixed rod 53, the degree of freedom of the guide plate 6 is restricted by the cooperation between the limit groove 531 and the limit block 62, so that the guide plate 6 can only slide vertically. Therefore, the guide plate 6 slides vertically downward under the action of the drive rod 55 and contacts the beryllium plate.
[0030] Multiple guide plates 6 form a frustum-shaped structure 63 on their inner sides. This frustum-shaped structure 63 guides and converges the splashed cutting fluid, ensuring sufficient flow. Simultaneously, it gradually reduces the flow area of the cutting fluid, increasing pressure and flow, thus enhancing its impact force and improving chip removal efficiency. Furthermore, the circular cross-section of the frustum-shaped structure 63 ensures the balance of the cutting fluid force on the electrode wire on the horizontal plane, guaranteeing wire stability and cutting quality. A cleaning wheel 56 is rotatably mounted at the lower end of the frustum-shaped structure 63. The cleaning wheel 56 is coaxially mounted with the wire-threading hole 21. During electrode wire installation, the cleaning wheel 56 and the wire-threading hole 21... The wire hole 21 is coaxially mounted, requiring the electrode wire to pass through the cleaning wheel 56 to complete the installation. When the guide plate 6 slides vertically downwards, it drives the cleaning wheel 56 to slide synchronously. The cleaning wheel 56 slides relative to the electrode wire, thus cleaning the surface of the electrode wire and preventing debris from adhering to the surface, which would affect the cutting efficiency. At the same time, when the wire EDM machine 1 starts working, the cleaning wheel 56 remains fixed, while the electrode wire needs to be fed. This causes the cleaning wheel 56 and the electrode wire to rotate relative to each other, cleaning the surface of the electrode wire. When the work is completed, the electrode wire stops feeding, the guide plate 6 resets, and drives the cleaning wheel 56 to move synchronously upwards. The cleaning wheel 56 moves relative to the electrode wire, cleaning the electrode wire and keeping its surface clean.
[0031] Preferably, the driving wheel 51, the double-sided gear ring 52, and the driven wheel 54 are all rotatably connected to the water spray plate 2. The water spray plate 2 can be rotatably connected to the water spray plate 2 by opening a circular groove, and the upper ends of the driving wheel 51, the double-sided gear ring 52, and the driven wheel 54 can be engaged with the circular groove by a circular sliding block. The guide plate 6 extends during operation and slides back into the fixing rod 53 after operation, making reasonable use of the space on the wire EDM machine 1, facilitating the installation of the beryllium plate and electrode wire, and not affecting the normal operation of the wire EDM machine 1.
[0032] In this embodiment, the driven wheel 54 has a circular array of telescopic grooves 541. The telescopic grooves 541 are fixedly installed at one end of the telescopic spring 542, and the other end of the telescopic spring 542 is fixedly connected to the telescopic wheel tooth 543. The telescopic wheel tooth 543 is slidably installed in the telescopic grooves 541. Specifically, after the guide plate 6 is fully extended, the drive block 551 of the drive rod 55 moves to the top of the drive groove 61 of the guide plate 6. Under the action of the fixed rod 53, the guide plate 6 can only slide vertically and cannot rotate. This causes the guide plate 6 to obstruct the rotation of the drive rod 55 through the drive groove 61. The drive rod 55 remains fixed, which in turn drives the driven wheel 54 to remain fixed. At this time, the double-sided gear ring 52 continues to rotate. The inner teeth of the double-sided gear ring 52 mesh with the telescopic gear teeth 543. With the driven wheel 54 fixed, the telescopic gear teeth 543, under the action of the double-sided gear ring 52, squeeze the telescopic spring 542 and slide it into the telescopic groove 541, thereby ensuring the stability of the rotation of the double-sided gear ring 52. When the double-sided gear ring 52 reverses, the guide plate 6 will no longer obstruct the rotation of the drive rod 55, which causes the driven wheel 54 to reverse. The driven wheel 54 drives the drive rod 55 to reverse, and the drive rod 55 drives the guide plate 6 to reset through the drive block 551.
[0033] In this embodiment, a drainage surface 561 is provided above the cleaning wheel 56, and an insulating pad 562 is provided below the drainage surface 561; Specifically, the drainage surface 561 guides the cutting fluid, preventing it from coming into perpendicular contact with the cleaning wheel 56, which would obstruct the flow of the cutting fluid and reduce its flow rate. At the same time, the insulating gasket 562 in the middle isolates the current emitted by the pulse generator, thereby ensuring the safety of cutting.
[0034] In this embodiment, a spiral flow channel 64 is provided on the flow guide plate 6; Specifically, the spiral guide groove 64 guides the flow of cutting fluid, causing it to flow in a spiral shape, increasing the flow rate of the cutting fluid, thereby enhancing its impact force and ensuring effective chip removal.
[0035] In this embodiment, the flow boosting component 7 includes a drive wheel 71, a rotating shaft 72, flow boosting blades 73, a crank-rocker mechanism 74, a slider 75, and a reciprocating spring 76. The drive wheel 71 is located on one side of the double-sided gear ring 52 and is symmetrically installed with the drive wheel 51. The drive wheel 71 is rotatably mounted on the bottom of the spray plate 2, and the rotating shaft 72 is fixedly mounted on the drive wheel 71. The top end of the rotating shaft 72 is located in the adjustment cavity 23, and the flow boosting blades 73 are fixedly mounted in the middle of the rotating shaft 72. The top end of the rotating shaft 72 is connected to the crank-rocker mechanism 74. The slider 75 is mounted on the crank-rocker mechanism 74. The slider 75 is slidably mounted in the adjustment cavity 23. The bottom end of the slider 75 has an extrusion groove 751, and a flow boosting plate 8 is provided below the slider 75. The flow boosting plate 8 is located in the cutting fluid channel 22. The flow boosting plate 8 has an extrusion groove 751 that cooperates with the slider 75, and the flow boosting plate 8 is connected to the adjustment cavity 23 by a reciprocating spring 76.
[0036] Specifically, the drive wheel 71 is located on one side of the double-sided gear ring 52 and is symmetrically installed with the drive wheel 51. The drive wheel 71 is rotatably mounted on the bottom of the spray plate 2. After the guide plate 6 slides out, cutting begins. The speed sensor 3 monitors the cutting speed and controls the rotation speed of the drive motor 4 according to the cutting speed. The drive motor 4 continues to rotate, which in turn drives the double-sided gear ring 52 to rotate through the drive wheel 51. The outer teeth of the double-sided gear ring 52 mesh with the teeth of the drive wheel 71, causing the drive wheel 71 to rotate. Meanwhile, the driven wheel 54 is driven by the telescopic gear 543. The drive wheel 71 is fixedly mounted with a rotating shaft 72. The top of the rotating shaft 72 is located inside the adjustment chamber 23. Sealing gaskets are provided at the connection points between the rotating shaft 72 and the cutting fluid channel 22 to ensure the sealing of the cutting fluid channel 22 and prevent leakage. A flow-enhancing blade 73 is fixedly mounted at the middle of the rotating shaft 72. When the drive wheel 71 rotates, it drives the rotating shaft 72 to rotate synchronously. The rotating shaft 72 drives the flow-enhancing blade fixedly mounted on it to rotate. The flow-enhancing blade adjusts its rotation speed according to the cutting speed. When the cutting speed increases, the rotation speed of the flow-enhancing blade 73 increases. The increased speed of the rotating shaft 72 leads to increased efficiency in the delivery of cutting fluid and increased flow rate. A crank-rocker mechanism 74 is connected to the top of the rotating shaft 72. A slider 75 is mounted on the crank-rocker mechanism 74 and slidably installed within the adjusting cavity 23. A groove is provided at the top of the adjusting cavity 23, and the top of the slider 75 is located within the groove, allowing it to slide horizontally. A squeezing groove 751 is provided at the bottom of the slider 75, and a flow booster plate 8 is located below the slider 75. The flow booster plate 8 is located within the cutting fluid flow channel 22, and a squeezing groove 751 that cooperates with the slider 75 is provided on the flow booster plate 8. The regulating chambers 23 are connected by a reciprocating spring 76. When the rotating shaft 72 rotates, it simultaneously drives the crank-rocker mechanism 74 to move. The crank-rocker mechanism 74 drives the slider 75 to reciprocate. When the slider 75 slides along the direction of the booster plate 8, the slider 75 pushes the booster plate 8 to slide vertically downward through the extrusion groove 751 opened on it. The booster plate 8 reduces the volume of the cutting fluid flow channel 22, thereby pressurizing the cutting fluid, thereby increasing the flow rate of the cutting fluid and increasing the flow of the cutting fluid. When the slider 75 returns to its original position away from the booster plate 8, the booster plate 8 returns to its original position under the action of the reciprocating spring 76.
[0037] In this embodiment, the crank-rocker mechanism 74 includes a crank 741 and a rocker arm 742; one end of the crank 741 is fixedly installed to the rotating shaft 72, the other end of the crank 741 is rotatably connected to the rocker arm 742, and the rocker arm 742 is rotatably connected to the slider 75; the slider 75 is eccentrically installed to the crank 741. Specifically, crank 741 is fixedly connected to rotating shaft 72 and rotates synchronously with rotating shaft 72, thereby causing crank 741 to drive rocker arm 742 connected to it to swing. Rocker arm 742 pulls slider 75 to slide horizontally. Slider 75 is eccentrically mounted with crank 741, thereby giving the crank-slider structure composed of crank 741, rocker arm 742 and slider 75 a quick-return characteristic. This allows slider 75 to slide quickly forward and slowly return along the direction of flow booster plate 8, thereby giving flow booster plate 8 a faster speed when sliding downward, ensuring the extrusion pressure on the cutting fluid. Flow booster plate 8 returns to its original position more slowly to avoid disturbing the cutting fluid in the cutting fluid channel 22.
[0038] In this embodiment, the booster plate 8 is provided with a pressure boosting protrusion 81, which corresponds to the outlet of the cutting fluid channel 22. Specifically, the pressure boosting bump 81 is used to enhance the squeezing force of the flow booster plate 8 on the cutting fluid, thereby ensuring the flow rate of the cutting fluid and ensuring a stable increase in the flow rate of the cutting fluid. The pressure boosting bump 81 corresponds to the outlet, so that there is a pressure boosting bump 81 above each outlet, thereby making the cutting fluid flowing out of the outlet have a larger initial velocity, thus ensuring the flow rate of the cutting fluid and avoiding the phenomenon of cutting fluid splashing, ensuring the stability of the cutting fluid spray.
[0039] In this embodiment, the pressure-boosting protrusion 81 is a hemispherical structure 82; Specifically, the hemispherical structure 82 reduces the resistance between the pressure boosting bump 81 and the cutting fluid, thereby ensuring the stability of the flow booster plate 8 sliding. At the same time, the hemispherical structure 82 can generate uniform extrusion pressure, ensuring the stability of the cutting fluid flow.
[0040] In this embodiment, a flow divider 221 is provided in the cutting fluid flow channel 22. The flow divider 221 corresponds to the flow booster blade 73, and a through hole is provided in the middle of the flow divider 221. Specifically, the flow divider 221 guides the flow direction of the cutting fluid through its shape, allowing the cutting fluid to flow evenly from both sides, thus quickly filling the cutting fluid channel 22 and ensuring the stability of the cutting fluid delivery. When the flow booster blade 73 rotates, it agitates the cutting fluid to flow rapidly, and the cutting fluid flow comes into contact with the flow divider 221, flowing evenly from both sides of the flow divider 221 and quickly filling the cutting fluid channel 22. The through hole in the middle of the flow divider 221 is used for the flow of cutting fluid. When the flow booster plate 8 slides vertically downward to increase pressure, the flow divider 221 reduces the obstruction effect on the cutting fluid through the through hole, thereby ensuring the stable outflow of cutting fluid.
[0041] When using the beryllium window preparation cutting equipment of the present invention, the operator completes the installation of the electrode wire and fixes the beryllium plate on the wire EDM machine 1 with a clamp. Then, the drive motor 4 is started, and the drive motor 4 drives the drive wheel 51 to rotate synchronously. The drive wheel 51 drives the double-sided rotation, and the double-sided gear ring 52 drives the driven wheel 54 on its inner circumference to rotate synchronously. The driven wheel 54 drives the drive rod 55 to rotate synchronously. The drive rod 55 squeezes the drive groove 61 in the guide plate 6 through the drive block 551 on it, thereby pushing the guide plate 6 to slide vertically downward. The guide plate 6 drives the cleaning wheel 56 to move synchronously to clean the electrode wire. After the guide plate 6 is extended, the operation is completed.
[0042] The cutting fluid enters the cutting fluid channel 22 and is discharged from the outlet. The wire EDM machine 1 starts working. At this time, the speed sensor 3 detects the cutting speed of the wire EDM machine 1 and sends an electrical signal to the control console. The control console then controls the rotation of the drive motor 4. The drive motor 4 rotates and drives the drive wheel 51. The drive wheel 51 drives the drive wheel 71 to rotate through the double-sided gear ring 52. The driven wheel 54 remains fixed under the action of the telescopic gear 543. When the drive wheel 71 rotates, it drives the rotating shaft 72 to rotate synchronously. The rotating shaft 72 drives the flow booster blade 73 in the middle to rotate synchronously. At the same time, the rotating shaft 72 drives the crank 741 to rotate synchronously. The crank 741 pulls the rocker arm 742 to swing back and forth. The rocker arm 742 drives the slider 75 to slide back and forth. When the slider 75 slides along the direction of the flow booster plate 8, the slider 75 pushes the flow booster plate 8 to slide vertically downward through the squeezing inclined surface. When the slider 75 returns to its original position, the pressure booster protrusion 81 returns to its original position under the action of the reciprocating spring 76.
[0043] After processing is completed, drive motor 4 reverses, drive motor 4 drives drive wheel 51 to reverse, drive wheel 51 drives double-sided gear ring 52 to reverse, double-sided gear ring 52 drives driven wheel 54 to reverse, driven wheel 54 drives drive rod 55 to reverse, drive rod 55 drives guide plate 6 to reset.
