Description

Technical Field

[0001] This invention relates to the field of aerospace metal parts processing, specifically to an apparatus and method for processing aerospace metal brush seal parts. Background Technology

[0002] The slow wire EDM machine tool with cooling and dust prevention functions, as described in application number CN202421009504.5, includes a machine body and a connecting rod. A hollow frame is fixedly connected to the top front side of the machine body. Hollow plates are fixedly connected to the bottom left and right ends of the inner side of the hollow frame. A bidirectional lead screw is rotatably connected to the front side of the hollow plate. The rear end of the bidirectional lead screw passes through the hollow plate. Movable blocks are threaded to the front and rear sides of the outer walls of the two bidirectional lead screws. A first rotating shaft is rotatably connected to one side of the movable block. Clamping plates are provided on adjacent sides of the two hollow plates. The device can drive the rotating rod to rotate via a servo motor. The driving bevel gear will rotate accordingly, and the driven bevel gear will also rotate. The clamping plates on both sides will move towards the middle to limit and clamp the workpiece to be processed. The workpiece to be processed is not easily affected by external factors and will not shake or deviate during processing, thus ensuring the processing quality of the workpiece.

[0003] In the prior art, including the aforementioned patents, during the wire cutting process of aerospace brush seal parts, firstly, because the conventional nozzle position is fixed, the water flow direction does not match the trajectory of the broken wire splash. During cutting, the broken wire will splash or fall along the direction of the brush filament. However, the conventional vertical water spray direction is perpendicular to the trajectory of the broken wire, which cannot form a "forward guidance". Instead, it may "slap" the broken wire back into the cutting area, aggravating the accumulation. This causes the cut metal wire to come into continuous contact with the wire-cut copper wire, resulting in short circuits and frequent breakage of the copper wire. This requires multiple wire threading and reprocessing, which seriously affects the delivery schedule. Secondly, when cutting by immersing and cooling with deionized water, there is a lack of function to collect the broken wire. Similarly, the broken wire will come into contact with the wire-cut copper wire, resulting in short circuits. Summary of the Invention

[0004] The problem this invention aims to solve is the following: short circuits caused by broken wires coming into contact with copper wires during rinsing and soaking cooling cutting, and the mismatch between water flow and the trajectory of broken wires. There is also the lack of a function to collect broken wires during deionized water soaking cooling cutting, which leads to short circuits caused by broken wires coming into contact with the wire-cut copper wires.

[0021] The water suction port is located on the arc-shaped side wall of the second fixed base, and the water suction port is located at the bottom of multiple second conical nozzles.

[0023] The inner cavity sidewall of the vortex interface is provided with multiple vortex guide plates arranged in a ring array.

[0024] A method for processing aerospace metal brush seal parts includes the following operational steps:

[0025] S1: First, place the metal brush seal part on the worktable, clamp and fix it by clamping the workpiece, start the wire feeding mechanism, and while supplying power to the copper wire, drive the copper wire to be fed from the wire feeding end to the wire receiving end, and contact the metal wire on the outside of the metal brush seal part to perform slow wire feeding and cutting.

[0026] S2: Start the water pump. The water pump delivers the deionized water cooled in the refrigeration unit to the first nozzle assembly and the second nozzle assembly. The water is then sprayed out through the first and second conical nozzles. The intelligent mini valve controls the frequency of water spraying, allowing the water to be sprayed out sequentially from left to right or from right to left to rinse the cut metal wire.

[0027] S3: During the flushing process, the direction of the water spray from the first and second conical nozzles can be adjusted by starting the first and second micro motors, thereby adjusting the water spray angle and focusing on flushing the broken metal wires. Finally, the flushed metal wires fall onto the workbench and are washed into the inner cavity of the drainage component by the water flow for temporary storage.

[0028] S4: In addition, when the cooling water cooling speed is not good, the sealing expansion wall can be activated to raise the sealing expansion wall and form a trough-shaped water storage tank. A large amount of deionized water is injected into the water tank through the water injection pipe to submerge the top of the metal brush seal parts. At this time, the water pump is started to change the water supply mode to the water pumping mode.

[0029] S5: Activate the second telescopic arm to adjust the orientation angle of the filter screen so that the filter screen can be close to the surface of the metal brush seal parts. Then, the water flows through the filter screen and enters the inner cavity of the vortex interface. The water flow is pumped back into the cooling device for cooling and circulation. The adsorbed broken wires accumulate in the collection screen groove to facilitate the cleaning of the metal wires later.

[0030] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0031] This invention delivers cooled deionized water to a nozzle, where the water flows out in an arc-shaped pattern, creating a "forward-guided" impact motion aligned with the cutting rotation direction. This impact water flow guides the broken wire to one side, preventing the metal wire from adhering to the copper wire due to eddy currents, reducing wire breakage and re-threading, and ensuring progress. Furthermore, the nozzle orientation is adjusted via an angle adjustment mechanism, allowing for flexible rinsing in an oscillating manner, expanding the cleaning range, eliminating dead angles, and reducing the probability of metal wire adhesion. Additionally, when the cooling effect is insufficient, a water storage tank is activated. Once filled, the system switches to pumping mode, adjusting the suction port to be close to the part surface, and the water flow... After passing through a filter, the water enters the vortex interface and forms a vortex-like flow under the action of the guide vanes. This enhances the adsorption force, accelerates the flow rate, and expands the range, maximizing the collection of broken wires. The filtered water is then circulated and cooled, and the broken wires are concentrated in the collection tank for easy cleaning, preventing short circuits caused by broken wires falling off. This method solves the problem of short circuits caused by broken wires coming into contact with copper wires in both flushing and immersion cooling cutting modes. It also solves the problem of accumulation and short circuits caused by the mismatch between the water flow direction and the trajectory of the broken wires. This method achieves efficient collection of broken wires during deionized water immersion cooling cutting, preventing them from coming into contact with copper wires and causing short circuits.

[0075] A method for processing aerospace metal brush seal parts includes the following operational steps:

[0076] S1: First, place the metal brush seal part on the worktable 4, clamp and fix it by clamping the workpiece 41, start the wire feeding mechanism 3, and while powering the copper wire 6, drive the copper wire 6 to be fed from the wire feeding end 32 to the wire receiving end 33, and contact the metal wire on the outside of the metal brush seal part to perform slow wire feeding and cutting of the metal wire.

[0077] S2: Start the water pump 52, and the deionized water cooled in the refrigeration device 51 is delivered to the first nozzle assembly 323 and the second nozzle assembly 333 and then sprayed out through the first conical nozzle 324 and the second conical nozzle 334. With the help of the intelligent mini valve, the frequency of water spraying can be controlled so that the water flow can be sprayed out from left to right or from right to left to rinse the cut metal wire.

[0078] S3: During the flushing process, the direction of the water spray from the first conical nozzle 324 and the second conical nozzle 334 can be adjusted by starting the first micro motor 3234 and the second micro motor 3332, so as to adjust the water spray angle and concentrate on flushing the broken metal wire. Finally, the flushed metal wire falls onto the workbench 4 and is washed into the inner cavity of the drainage component 20 by the water flow for temporary storage.

[0079] S4: In addition, when the cooling water cooling speed is not good, the sealing telescopic wall 2 can be activated to raise the sealing telescopic wall 2 and form a trough-shaped water storage tank. A large amount of deionized water is injected into the water tank through the water injection pipe 30 to submerge the top of the metal brush seal parts. At this time, the water pump 52 is activated to change the water supply mode to the water pumping mode.

[0080] S5: Activate the second telescopic arm 3324 to adjust the orientation angle of the filter screen 3351 so that the filter screen 3351 can be close to the surface of the metal brush seal part. Then, the water flows through the filter screen 3351 and enters the inner cavity of the vortex interface 336. The water is then sent back into the cooling device 51 by the water pump 52 for cooling and circulation. The adsorbed broken wires accumulate in the collection screen trough 3352 to facilitate the cleaning of the metal wires later.

[0081] Working principle and usage process of this invention:

[0082] First, place the metal brush seal part on the workbench 4, clamp and fix it by clamping the workpiece 41, start the wire feeding mechanism 3, and while supplying power to the copper wire 6, drive the copper wire 6 to be fed from the wire feeding end 32 to the wire receiving end 33 and contact the metal wire on the outside of the metal brush seal part.

[0083] At the same time, the water pump 52 is started, and the deionized water cooled in the refrigeration device 51 is delivered to the first nozzle assembly 323 and the second nozzle assembly 333 and then sprayed out through the first conical nozzle 324 and the second conical nozzle 334. With the help of the intelligent mini valve to control the frequency of water spraying, the water can be sprayed out sequentially from left to right or from right to left to wash the cut metal wire. By spraying water sequentially, the broken metal wire can be washed in the same direction as the cutting rotation direction, so that the broken metal wire moves to one side under the sequential water flow. This avoids the eddy effect caused by the disorderly washing of the metal wire and the continuous washing of the water flow, which would cause the metal wire to rotate in the water flow and stick to the copper wire 6, causing a short circuit.

[0084] It should be noted that during the rinsing process, the direction of water spray from the first conical nozzle 324 and the second conical nozzle 334 can be adjusted by activating the first micro motor 3234 and the second micro motor 3332, thereby adjusting the spray angle. By adjusting the spray angle, the metal wire can be rinsed by oscillation during rinsing. Compared with the traditional fixed continuous rinsing, the angle-adjustable rinsing is more flexible and orderly, and the rinsing angle and range are large, avoiding rinsing dead corners. It can concentrate on rinsing the metal wire adsorbed on the copper wire 6, reducing the probability of metal wire adhesion and further avoiding the probability of short circuit. After rinsing, the metal wire falls onto the worktable 4 and is washed by the water flow into the inner cavity of the drainage component 20 for temporary storage.

[0085] In addition, when the cooling water cooling speed is not good, the sealing telescopic wall 2 can be activated to raise the sealing telescopic wall 2 and form a trough-shaped water storage tank. A large amount of deionized water is injected into the water tank through the water injection pipe 30 to submerge the top of the metal brush seal parts. At this time, the water pump 52 is activated to change the water supply mode to the water pumping mode.

[0086] The second telescopic arm 3324 is activated to adjust the orientation angle of the filter screen 3351, allowing the filter screen 3351 to be close to the surface of the metal brush seal parts. Then, the water flows through the filter screen 3351 and enters the inner cavity of the vortex interface 336. When the water flows into the inner cavity of the vortex interface 336, it is guided by the vortex guide plate 3361, causing the water flow to reverse and form a vortex. The vortex-shaped water flow has a greater adsorption effect, causing multiple rotating vortices to appear on the surface of the filter screen 3351. The flow rate is increased and the range of adsorption of metal wires is improved, maximizing the adsorption and collection of broken wires. Finally, the water flow filtered by the filter screen 3351 is pumped by the water pump 52 back into the cooling device 51 for cooling and recycling. The adsorbed broken wires accumulate in the collection mesh trough 3352 for easy cleaning of the metal wires later.
