Description

Technical Field

[0001] This utility model relates to the field of silicon diffusion, and in particular to a silicon diffusion carbon / carbon tooling for producing carbon fiber reinforced ceramic matrix plates. Background Technology

[0002] An existing patent (publication number: CN213357377U) discloses a silicon diffusion fixture, including a silicon diffusion reaction chamber. A support platform is set on the inner wall of the reaction chamber, and a support plate is placed on the support platform. The support plate divides the inner cavity of the reaction chamber into two parts: a lower silicon melting zone and an upper reaction zone. A reaction chamber top cover is provided on the top of the reaction chamber. Several silicon vapor channels are evenly arranged on the support plate. A placement groove is opened on the top of the support plate, avoiding the silicon vapor channels, or a pad is placed on the top of the support plate, avoiding the silicon vapor channels. However, when multiple parts to be processed are placed in the placement groove of this device, due to the circular design of the support plate, the space around each part varies greatly. This results in differences in the silicon diffusion effect of each part during the silicon diffusion operation, affecting the overall silicon diffusion effect. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a siliconizing carbon / carbon tooling for producing carbon fiber reinforced ceramic matrix plates. This tooling allows for the alteration of the tilt angle of the plate support block by varying the angles between the octagonal docking posts and octagonal docking grooves. Simultaneously, it changes the position of the drive post docking slider within the drive post docking groove, thereby altering the density of the siliconized plates and adapting to the batch processing requirements of different plates. Furthermore, the space around each siliconized plate is similar, resulting in similar siliconizing effects, good siliconizing results, and high siliconizing efficiency for plates in the same batch.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A silicon-infiltrating carbon / carbon tooling for producing carbon fiber reinforced ceramic matrix plates includes a silicon infiltrating furnace, a silicon infiltrating protective cover, a plate to be siliconized, an upper partition plate, a tooling support platform, a plate support platform, a plate support block, an internal adjustment drive column, and an adjustment drive linkage. The silicon infiltrating furnace opening is connected to the silicon infiltrating protective cover. The silicon infiltrating furnace has a silicon infiltrating working tank inside. The top of the silicon infiltrating working tank has a silicon powder support platform, and the silicon powder support platform has a silicon powder placement tank inside. The bottom of the silicon powder support platform has a partition plate mounting slot. The upper partition plate is adapted to the partition plate mounting slot and is connected to the partition plate mounting slot. The upper partition plate is inserted into the partition plate mounting slot and fixed. The surface of the upper partition plate has gaseous silicon passage holes. The tooling support platform is adapted to the silicon infiltrating working tank and is connected to the silicon infiltrating working tank. The tooling support platform slides inside the silicon infiltrating working tank. The bottom of the tooling support platform has a support platform positioning platform, and the bottom of the silicon infiltrating working tank has a support platform positioning slot.

[0006] The positioning platform of the bearing platform is adapted to the positioning groove of the bearing platform. The positioning platform of the bearing platform is connected to the positioning groove of the bearing platform and slides inside the positioning groove of the bearing platform. The end of the tooling bearing platform facing the opening has a tooling pick-up and put-out handle. There are side positioning slides on both sides of the tooling bearing platform. Plate bearing platforms are set on both sides of the tooling bearing platform. There are slide docking blocks at the bottom of the plate bearing platforms. The slide docking blocks are adapted to the side positioning slides and are connected to the side positioning slides. The slide docking blocks slide outside the side positioning slides. There are external connecting rod mounting columns inside the plate bearing platforms. There are drive column docking grooves inside the tooling bearing platforms. An internal adjustment drive column is set at the top of the tooling bearing platforms.

[0007] The bottom of the inner adjustment drive column has a drive column docking slider, which is adapted to the drive column docking groove. The drive column docking slider is connected to the drive column docking groove and slides inside the drive column docking groove. The drive column docking slider has a drive column operating handle inside. The inner adjustment drive column has inner connecting rod mounting platforms on both sides, and inner connecting rod mounting columns at the bottom of the inner connecting rod mounting platforms. One side of the adjustment drive connecting rod is rotatably connected to the inner connecting rod mounting column.

[0008] Beneficial effects: 1. When performing silicon infiltration on carbon fiber reinforced ceramic matrix plates, this utility model can change the tilt angle of the plate bearing block by different angles between the octagonal docking post and the octagonal docking groove, depending on the size and quantity of the plates to be siliconized. At the same time, the distance between the plate bearing platforms can be changed by changing the position of the drive post docking slider inside the drive post docking groove, thereby changing the density of the plates to be siliconized. This adapts to the batch processing requirements of different plates. In addition, the space around each plate to be siliconized is similar, so that the silicon infiltration processing effect of the same batch of plates is similar, the silicon infiltration effect is good, and the silicon infiltration efficiency is high.

[0009] 2. The plate support block of this utility model adopts a hollow design to reduce the contact area between the plate support block and the plate to be siliconized, so that gaseous silicon can more easily come into contact with the plate to be siliconized through the plate support block, thereby increasing the siliconizing effect of the plate to be siliconized.

[0010] 3. The silicon powder support platform of this utility model is located on the upper part of the plate support block. Since the density of gaseous silicon is greater than that of air, the gaseous silicon generated after the silicon powder in the silicon powder placement tank melts falls from the top and passes through the gaseous silicon through hole to the plate to be siliconized, thus completing the siliconization operation of the plate to be siliconized. This makes the contact between the plate to be siliconized and the gaseous silicon more sufficient, thereby further increasing the siliconization effect and siliconization efficiency of this device.

[0011] 4. In this utility model, the upper partition plate is inserted into the partition plate mounting groove, and each plate support block is individually connected to the plate support platform, so that the upper partition plate and plate support blocks can be replaced and maintained more conveniently, thereby avoiding the adhesion of gaseous silicon to the upper partition plate and plate support blocks after long-term use, which will affect subsequent processing.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0023] Example 1:

[0024] A siliconizing carbon / carbon tooling for producing carbon fiber reinforced ceramic matrix plates includes a siliconizing furnace 1, a siliconizing protective cover 2, a siliconized plate 4, an upper partition plate 5, a tooling support platform 9, a plate support platform 15, a plate support block 17, an internal adjustment drive column 19, and an adjustment drive connecting rod 20. The siliconizing furnace 1 is connected to the siliconizing protective cover 2 at its opening. The siliconizing furnace 1 has a siliconizing working tank 12 inside, and a silicon powder support platform 3 is located on top of the siliconizing working tank 12. The silicon powder support platform 3 is located above the plate support block 17. Because the density of gaseous silicon is greater than that of air, the gaseous silicon generated after the silicon powder in the silicon powder placement tank 8 melts falls from the top and passes through the gaseous silicon through hole 7 through the silicon powder to be siliconized plate 4 to complete the siliconizing operation on the siliconized plate 4. This makes the contact between the siliconized plate 4 and the gaseous silicon more sufficient, thereby further increasing the siliconizing effect and efficiency of this device. The silicon powder support platform 3 has a silicon powder placement... The bottom of the silicon powder support platform 3 has a partition plate mounting groove 6. The upper partition plate 5 is adapted to the partition plate mounting groove 6 and is connected to the partition plate mounting groove 6. The upper partition plate 5 is inserted into the partition plate mounting groove 6 and fixed. At the same time, each plate support block 17 is individually connected to the plate support platform 15, so that the upper partition plate 5 and the plate support block 17 can be replaced and maintained more conveniently. This avoids gaseous silicon adhering to the upper partition plate 5 and the plate support block 17 after long-term use, which will affect subsequent processing. The surface of the upper partition plate 5 has gaseous silicon passage holes 7. The tooling support platform 9 is adapted to the silicon diffusion operation tank 12 and is connected to the silicon diffusion operation tank 12. The tooling support platform 9 slides inside the silicon diffusion operation tank 12. The bottom of the tooling support platform 9 has a support platform positioning platform 10, and the bottom of the silicon diffusion operation tank 12 has a support platform positioning groove 11.

The plate bearing platform 15 has an external connecting rod mounting column 25 inside. The tooling bearing platform 9 has a drive column docking groove 21 inside. The upper part of the tooling bearing platform 9 is provided with an internal adjustment drive column 19.

The drive column docking slider 22 is adapted to the drive column docking groove 21. The drive column docking slider 22 is connected to the drive column docking groove 21 and slides inside the drive column docking groove 21. The drive column docking slider 22 has a drive column operating handle 28 inside. The inner adjusting drive column 19 has inner connecting rod mounting platforms 23 on both sides. The bottom of the inner connecting rod mounting platform 23 has an inner connecting rod mounting column 24. One side of the adjusting drive connecting rod 20 is rotatably connected to the inner connecting rod mounting column 24.

[0029] Example 4:

[0030] The adjustment drive linkage 20 of this utility model is rotatably connected to the outer linkage mounting column 25 on the other side. The top of the plate support platform 15 has an octagonal docking groove 27. The top of the plate support platform 15 is provided with a plate support block 17. The plate support block 17 adopts a hollow design to reduce the contact area between the plate support block 17 and the silicon-to-be-diluted plate 4, so that gaseous silicon can more easily come into contact with the silicon-to-be-diluted plate 4 through the plate support block 17, thereby increasing the silicon-diluted effect of the silicon-to-be-diluted plate 4. The bottom of the plate support block 17 has an octagonal docking post 26. The octagonal docking post 26 is adapted to the octagonal docking groove 27 and the octagonal docking post 26 is connected to the octagonal docking groove 27.

The plate bearing groove 18 connects to the silicon-dilutable plate 4, and the silicon-dilutable plate 4 is inserted into the plate bearing groove 18. When performing silicon diluting operation on carbon fiber reinforced ceramic matrix plates, the tilt angle of the plate bearing block 17 can be changed by different angles between the octagonal docking post 26 and the octagonal docking groove 27, depending on the size and quantity of the silicon-dilutable plates 4 to be processed. At the same time, the position of the drive post docking slider 22 in the drive post docking groove 21 is changed to change the distance between the plate bearing platforms 15, thereby changing the density of the silicon-dilutable plates 4, so as to adapt to the batch processing requirements of different plates. At the same time, the space around each silicon-dilutable plate 4 is similar, so that the silicon diluting processing effect of the same batch of silicon-dilutable plates 4 is similar, the silicon diluting effect is good, and the silicon diluting efficiency is high.
