Description

Technical Field

[0001] This utility model relates to the field of carbon fiber composite tooling, and more specifically, to a multi-layer space adjustable cage-type carbon fiber composite tooling. Background Technology

[0002] With the rapid development of science and technology in China and the maturity and stability of carbon fiber raw material production technology, the proportion of domestically produced lightweight materials that are resistant to high temperature and ablation in aerospace is increasing, and they are gradually benefiting civilian use. On this basis, the output of carbon fiber composite materials produced by high temperature furnaces and high temperature chemical vapor deposition furnaces is also expanding year by year.

[0003] However, the traditional fixed-layer tooling for producing carbon fiber composite materials in existing high-temperature furnaces and high-temperature chemical vapor deposition furnaces, such as graphite frames, ceramic supports, or simple stacking, suffers from poor stability, is prone to tipping over, has inaccurate layer height adjustment, low furnace space utilization, fixed gas flow field distribution that is difficult to adjust and optimize, and existing material manufacturing tooling does not have good furnace space utilization, does not have better mechanical properties at ultra-high temperatures, cannot significantly reduce tooling weight, and places a large load on the furnace structure, unlike lightweight materials which are easier to operate. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a multi-layer spatially adjustable cage-type carbon fiber composite tooling.

[0005] According to a first aspect of this utility model, a multi-layer spatially adjustable cage-type carbon fiber composite tooling is provided, comprising: an adjustable cage assembly, the adjustable cage assembly comprising: an air distribution plate, mounting holes, a support screw, a limiting nut, and air holes, wherein the air distribution plate is an independent module, the air distribution plate has mounting holes inside, the mounting holes are for the support screw to be inserted through, the support screw is mounted on the support screw, and the spacing between different groups of the air distribution plate is adjustable.

[0006] Preferably, the air distribution plate has air holes inside, and the air holes are evenly distributed and arranged.

[0007] Preferably, the support screw and the limiting nut are combined to form a rigid frame.

[0008] Preferably, the gas distribution plate is a low-density structure of needle-punched carbon fiber preform laminate, and the support screw and the limiting nut adopt a high-density structure.

[0009] Preferably, the air holes are arranged in a circular pattern on the air distribution plate, and the multiple sets of support screws are arranged in a circular pattern.

[0010] 1. This utility model utilizes the cooperation of a gas distribution plate, a supporting screw, and a limiting nut. The gas distribution plate, as an independent module, can be freely fitted onto any position of the supporting screw. This not only allows for the addition or reduction of the number of layers but also enables the independent setting of the optimal height space for each layer. It is fully adaptable to products of different batches, sizes, shapes, and especially irregularly shaped parts. Because the layer height can be precisely adjusted, the size of the airflow channels between the layers of the gas distribution plate can be actively designed. Combined with the arrangement of air holes on the gas distribution plate, the gas flow is evenly distributed, achieving a more uniform and controllable gas flow field throughout the furnace cavity. This multi-layer adjustable cage-type carbon fiber composite tooling allows for precise adjustment of the layer height, enabling the addition or reduction of the number of layers and the independent setting of the optimal height space for each layer. It is fully adaptable to products of different batches, sizes, shapes, and especially irregularly shaped parts, improving the practicality and adjustability of the device.

[0011] 2. This utility model utilizes the combination of a gas distribution plate, a support screw, and a limiting nut. The gas distribution plate adopts a low-density structure of a 2.5D carbon fiber prefabricated laminate with a specific needle-punched layer. The entire assembly consists of a gas distribution plate and a high-density support screw and limiting nut. After the tooling is manufactured, it has a better utilization rate of furnace space than traditional tooling. It achieves better mechanical properties of the multi-layer adjustable cage-type carbon fiber composite tooling under ultra-high temperature conditions, significantly reduces the weight of the tooling, reduces the load on the furnace structure, and the lightweight material makes it easier to operate (loading and unloading the furnace), thus improving the practicality and functionality of the device.

[0023] like Figure 1-4 As shown, one embodiment of this utility model is provided:

[0024] A multi-layer spatial adjustable cage-type carbon fiber composite tooling. The support screw 213 and limit nut 214 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art.

[0025] Includes: a cage-type component, which includes: a distribution plate 211, a mounting hole 212, a support screw 213, a limit nut 214, and an air hole 215. The distribution plate 211 is an independent module. The distribution plate 211 has a mounting hole 212 inside, through which the support screw 213 is inserted. The limit nut 214 is installed on the support screw 213. The spacing between different groups of distribution plates 211 is adjustable.

[0026] When using this multi-layer adjustable cage-type carbon fiber composite tooling, the air distribution plate 211, as an independent module, can be freely fitted onto any position of the support screw 213. This not only allows for the addition or reduction of the number of layers, but also enables the independent setting of the optimal height space for each layer, making it fully adaptable to products of different batches, sizes, shapes, and especially irregularly shaped parts.

[0027] The air distribution plate 211 has air holes 215 inside, and the air holes 215 are evenly distributed and arranged.

[0028] Because the layer height can be precisely adjusted, the size of the airflow channels between the layers of the gas distribution plate 211 can be actively designed. Combined with the arrangement of the air holes 215 on the gas distribution plate 211, the gas flow field is evenly distributed, resulting in a more uniform and controllable gas flow field throughout the furnace cavity.

[0029] The support screw 213 and the limiting nut 214 combine to form a rigid frame;

[0030] The rigid support frame, consisting of high-density support screws 213 and limiting nuts 214, provides a stable support foundation, ensuring the safety and stability of multi-layer stacking and avoiding the swaying risk of traditional stacking.

[0031] The air distribution plate 211 is a low-density structure of needle-punched carbon fiber preform laminate, while the support screw 213 and the limiting nut 214 adopt a high-density structure.

[0032] The gas distribution plate 211 adopts a low-density structure of 2.5D carbon fiber prefabricated laminate with specific needle-punched layers. The whole assembly consists of the gas distribution plate 211, the high-density support screw 213, and the limiting nut 214. After the tooling is manufactured, it has better furnace space utilization than traditional tooling, better mechanical properties under ultra-high temperature conditions, can significantly reduce the weight of the tooling, reduce the load on the furnace structure, and the lightweight material makes it easier to handle loading and unloading from the furnace. It is made of the same material as the product, has good stability, and does not contaminate the product.

[0033] The air holes 215 are arranged in a ring on the air distribution plate 211, and the multiple sets of support screws 213 are arranged in a ring.

[0034] The vents 215 are arranged in a ring on the gas distribution plate 211, and the multiple sets of support screws 213 are arranged in a ring, which makes it easier to assemble the gas distribution plate 211, support screws 213 and limit nuts 214, and makes the gas flow field more uniform and controllable in the entire furnace cavity.

[0035] Working principle:

[0036] When using this multi-layer adjustable cage-type carbon fiber composite tooling, the gas distribution plate 211, as an independent module, can be freely fitted onto any position of the support screw 213. It can not only increase or decrease the number of layers, but also independently set the optimal height space for each layer, making it fully adaptable to products of different batches, sizes, shapes, and especially irregularly shaped parts. Since the layer height can be precisely adjusted, the size of the airflow channels between the layers of the gas distribution plate 211 can be actively designed. Combined with the arrangement of the air holes 215 on the gas distribution plate 211, the gas flow field is evenly distributed, achieving a more uniform and controllable gas flow field in the entire furnace cavity space.

[0037] The gas distribution plate 211 adopts a low-density structure of 2.5D carbon fiber prefabricated laminate with specific needle-punched layers. The whole assembly consists of the gas distribution plate 211, the high-density support screw 213, and the limiting nut 214. After the tooling is manufactured, it has better furnace space utilization than traditional tooling, better mechanical properties under ultra-high temperature conditions, and can significantly reduce the weight of the tooling and reduce the load on the furnace structure. At the same time, the lightweight material makes it easier to handle loading and unloading from the furnace. It is made of the same material as the product, has good stability, and does not contaminate the product. The operation is now complete.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
