Description

Technical Field

[0001] This utility model relates to a winding tooling for rapid production of composite tubular products. Background Technology

[0002] Resin-based carbon fiber composites possess superior properties such as high specific strength and specific stiffness, strong design flexibility, good fatigue fracture resistance, corrosion resistance, and good dimensional stability, making them widely used high-performance structural materials in aerospace, transportation, and other fields. Carbon fiber composite tubing is one of the most widely used and numerous basic carbon fiber products and an important application form of carbon fiber composites.

[0003] Due to the excellent properties of carbon fiber composite pipes, their application demand is rapidly increasing across various fields. To meet this demand, it is necessary to improve the production and processing speed of carbon fiber composite pipes. To accelerate the production speed of composite pipes, the current common process involves using long-length tooling for winding and curing, followed by demolding and cutting after curing to obtain carbon fiber composite tubular products of suitable dimensions.

[0004] However, when using long-length tooling for winding, the tooling is subjected to lateral loads during the winding process, which will cause significant flexural deformation, resulting in insufficient straightness of the cured structure, making it difficult or even impossible to demold. Utility Model Content

[0005] The main purpose of this invention is to provide a winding tooling for rapid production of composite tubular products, in order to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A winding tooling for rapid production of composite tubular products includes multiple coaxially arranged winding columns, an internal connecting shaft between two adjacent winding columns, first threaded holes on both sides of each winding column, internal connecting discs on both sides of each internal connecting shaft, second threaded holes on each internal connecting disc, external connecting shafts on the outer sides of each winding column at both ends, external connecting discs on both ends of each external connecting shaft, and third threaded holes on each external connecting disc.

[0008] Preferably, four winding columns are provided, and the four winding columns are evenly distributed along the horizontal direction.

[0009] Preferably, there are three internal connecting shafts, which are distributed horizontally between two adjacent winding columns.

[0010] Preferably, a bearing is provided on the intermediate internal connecting shaft.

[0011] Preferably, a support rod is provided below the bearing.

[0012] Preferably, a machine connecting rod is provided on the outer side of the external connecting shaft.

[0013] Preferably, a machine connecting plate is provided on the inner side of the machine connecting rod, and a fourth threaded hole is provided on the machine connecting plate.

[0014] Preferably, the diameter values ​​of the winding column, the inner connecting plate, and the outer connecting plate are all the same.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] 1. This utility model, by setting multiple coaxial winding columns, enables the molding of multiple products in a single assembly, effectively reducing the assembly frequency of the tooling and thus improving production efficiency. The short length of each winding column facilitates demolding. A support rod added to the middle of the tooling helps to bear the load and reduce lateral bending deformation, thereby improving the dimensional accuracy of the product. The support rod and the tooling are connected by bearings, ensuring smooth rotation of the tooling and preventing wear on both the tooling and the support rod.

[0017] 2. This utility model uses bolts and internal connecting shafts to connect multiple winding columns. During long-term use, if the surface of a single winding column is damaged by bumps, only the damaged winding column needs to be replaced, without the need for overall replacement, thereby reducing the maintenance and use costs of the tooling.

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0023] like Figures 1-3 As shown, the winding fixture for rapid production of composite tubular products provided in this embodiment includes multiple coaxially arranged winding columns 1, an internal connecting shaft 2 between two adjacent winding columns 1, first threaded holes 3 on both sides of the winding column 1, internal connecting discs 4 on both sides of the internal connecting shaft 2, second threaded holes 5 on the internal connecting discs 4, external connecting shafts 6 on the outer sides of the winding columns 1 at both ends, external connecting discs 7 at both ends of the external connecting shaft 6, and third threaded holes 8 on the external connecting discs 7.

[0024] By setting multiple coaxial winding cylinders 1, multiple products can be molded in a single assembly, effectively reducing the assembly frequency of tooling and thus improving production efficiency. The length of each winding cylinder 1 is designed to be short, facilitating demolding.

[0025] Multiple winding columns 1 are connected together by bolts and internal connecting shaft 2. During long-term use, if the surface of a single winding column 1 is damaged by bumps, only the damaged winding column 1 needs to be replaced, without replacing the whole thing, thus reducing the maintenance and use costs of the tooling.

[0026] In this embodiment, as Figure 1 As shown, there are four winding columns 1, which are evenly distributed in the horizontal direction. There are three internal connecting shafts 2, which are distributed in the horizontal direction between two adjacent winding columns 1. Multiple products are wound and formed at the same time, which significantly improves production efficiency.

[0027] In this embodiment, as Figure 1 As shown, a bearing 9 is installed on the middle internal connecting shaft 2 to improve the support force and ensure the smooth rotation of the tooling.

[0028] In this embodiment, as Figure 1 As shown, a support rod 10 is provided below the bearing 9 to assist in bearing, reduce the lateral bending deformation of the tooling, and improve the dimensional accuracy of the product molding.

[0029] In this embodiment, as Figure 1 As shown, a machine connecting rod 11 is provided on the outer side of the external connecting shaft 6. The tooling is connected to the winding equipment through the machine connecting rod 11. Different models of winding equipment can be adapted by using machine connecting rods 11 with different joint designs.

[0030] In this embodiment, as Figure 3As shown, a machine connecting plate 12 is provided on the inner side of the machine connecting rod 11. The machine connecting plate 12 is provided with a fourth threaded hole 13, which is used for bolt connection, making it easy to install and disassemble.

[0031] In this embodiment, as Figure 1 As shown, the diameter values ​​of the winding column 1, the inner connecting plate 4, and the outer connecting plate 7 are all the same, making the tooling smoother and the winding molding effect better.

[0032] In summary, this embodiment achieves the molding of multiple products in a single assembly by setting multiple coaxial winding cylinders 1, effectively reducing the assembly frequency of the tooling and thus improving production efficiency. The shorter length of each winding cylinder 1 facilitates demolding. The addition of a support rod 10 in the middle of the tooling helps to support and reduce lateral bending deformation, thereby improving the dimensional accuracy of the product molding. The support rod 10 is connected to the tooling via a bearing 9, ensuring smooth rotation of the tooling and preventing wear on both the tooling and the support rod 10. By connecting multiple winding cylinders 1 with bolts and an internal connecting shaft 2, if a single winding cylinder 1 suffers surface damage during long-term use, only the damaged winding cylinder 1 needs to be replaced, eliminating the need for complete replacement and reducing the maintenance and usage costs of the tooling.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
