Description

Technical Field

[0001] The utility model relates to the technical field of pipe rolling, in particular to a carbon fiber tube mold and a pipe rolling machine. Background Art

[0002] Carbon fiber composite materials have the characteristics of light weight, high strength, high temperature resistance, good fatigue performance, etc., and are widely used in the fields of satellite antennas, unmanned aerial vehicles, automobiles, sports goods, etc. Carbon fiber tubes are generally made by processes such as fiber winding, prepreg molding, pultrusion, and pipe rolling. Among them, fiber winding is suitable for carbon fiber pipe fittings with a larger diameter, the efficiency of prepreg molding is not high, the pultrusion process only has 0° carbon fiber, and the pipe rolling process is the most widely used.

[0003] Carbon fiber pipe rolling is formed by cutting, rolling, winding, curing, core removal, grinding, and cutting short processes of carbon fiber prepregs at different angles. During the use of the pipe rolling mold, there are scratching and bending situations. Therefore, these molds usually need to be reprocessed as a whole, which is inconvenient for maintenance and has a high cost. At the same time, long carbon fiber tubes cannot use short molds, and the versatility between molds is poor.

[0004] For example, a carbon fiber tube forming device and a method for processing carbon fiber tubes disclosed in Chinese Patent Application No.: CN201611033362.6. Specifically disclosed is "placing the carbon fiber cloth to be processed flat on the flat plate, by rotating the nut, driving the lower pressing plate to rise or lower, so that the compression spring compresses or elongates, thereby adjusting the pressing degree of the lower pressing plate, and thus adjusting the gap between the scraper and the flat plate. Then applying the adhesive on the surface of the carbon fiber cloth, by stretching the carbon fiber cloth, the adhesive is evenly coated on the surface of the carbon fiber cloth under the scraping action of the scraper, and then one end of the carbon fiber cloth coated with the adhesive is attached to the core mold coated with the release agent, and by manually rotating the rocker to drive the core mold to rotate, the carbon fiber cloth is continuously wound on the core mold". The core mold has a fixed length, and it needs to be reprocessed as a whole during maintenance, which is inconvenient for maintenance; at the same time, the core mold has a fixed length, and the versatility between molds is poor.

[0005] Another example is the new pipe rolling equipment for carbon fiber tubes disclosed in Chinese Patent Application No.: CN202021485625.9. Its core mold length is also fixed, and the above problems will also exist. Summary of the Utility Model

[0006] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide a carbon fiber tube mold, which can not only be partially replaced, is convenient for maintenance, but also has an adjustable length, strong versatility and lower cost, thereby overcoming the deficiencies of the existing technology.

[0007] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] This application provides a carbon fiber tube mold, which includes a main body mold and at least one section of an adapter mold; a first scale line and a groove are provided at the first end of the main body mold, and a first connector is provided at the second end of the main body mold;

[0009] A connection hole is provided at the first end of the adapter mold, and a second connector and a second scale line are provided at the second end of the adapter mold; both the first connector and the second connector can be inserted into adjacent connection holes.

[0014] Preferably, the main body mold and the adapter mold are fittings made of aluminum alloy or stainless steel.

[0015] This application provides a pipe winding machine, which includes the carbon fiber tube mold described above, as well as a pipe pressing shaft and a pipe winding shaft. The pipe pressing shaft is arranged on a lifting device. The pipe pressing shaft and the pipe winding shaft are arranged in a triangular shape, and a pipe winding channel is formed between the pipe pressing shaft and the pipe winding shaft. The carbon fiber tube mold can be rotatably inserted through this pipe winding channel.

[0016] Preferably, the pipe winding shaft is arranged on a workbench. The lifting device includes a servo linear module, and the output end of the servo linear module is connected to the mounting bracket of the pipe pressing shaft, and this mounting bracket can slide up and down on the frame.

[0017] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, the main body mold and several sections of the adapter mold are combined together, so that the overall length of the mold can be increased.

[0030] Among them, the body mold 10 and several sections of adapter molds 20 are combined together, so that the overall length of the mold can be adjusted, making it more convenient to maintain and having a lower cost.

[0031] The present application provides a carbon fiber tube mold 1, which includes a main body mold 10 and at least one section of an adapter mold 20; a first scale line 12 and a groove 13 are provided at the first end of the main body mold 10, and a first connector 11 is provided at the second end of the main body mold 10; a connection hole 21 is provided at the first end of the adapter mold 20, and a second connector 22 and a second scale line 23 are provided at the second end of the adapter mold 20; both the first connector 11 and the second connector 22 can be inserted into the adjacent connection hole 21. The main body mold 10 and the adapter mold 20 have a certain length, and the specific length can be set according to needs. In this embodiment, the main body mold 10 has one section, and the adapter mold 20 has several sections. The main body mold 10 and the adapter mold 20 are connected together, and then the adapter molds 20 are sequentially joined together, making the length of the mold longer; reducing the number of adapter molds 20 makes the length of the mold shorter. Therefore, this kind of mold has good versatility; during maintenance, only the corresponding section needs to be replaced, and the cost is lower. At the same time, the first scale line 12 and the second scale line 23 can be used as references and can be used to locate the position of the carbon fiber. During use, the first scale line 12 and the second scale line 23 are aligned for easy observation. When the main body mold 10 and the adapter mold 20 are assembled, the first connector 11 of the main body mold 10 is fixed in the connection hole 21 of the first section of the adapter mold 20. When the adapter molds 20 are connected, the second connector 22 is inserted into the adjacent connection hole 21, so that several sections of the adapter molds 20 can be joined together. The groove 13 facilitates demolding. After the carbon fiber is cured, the mold is pulled at the groove 13, and the carbon fiber and the mold will be separated, and the demolding is very convenient.

[0032] Preferably, hanging holes 14 are provided on the first connector 11 and the second connector 22. After the carbon fiber is wound around the mold, the mold is taken out, and then a counterweight is hung at the position of the hanging hole 14, which is beneficial to improving the straightness of the carbon fiber tube.

[0033] Preferably, the main body mold 10 and the adapter mold 20 are cylinders or square columns, and the specific structural form can be set according to needs without specific limitations. In this embodiment, the main body mold 10 and the adapter mold 20 are cylinders.

[0034] Preferably, the first connector 11 and the second connector 22 are one of a threaded post, a plug pin, a rivet, and a tenon, and the connection hole 21 is one of a threaded hole, a pin hole, a rivet hole, and a mortise hole. Among them, the threaded post matches the threaded hole, the plug pin matches the pin hole, the rivet matches the rivet hole, and the tenon matches the mortise hole. In this embodiment, the first connector 11 is a threaded post, and the connection hole 21 is a threaded hole.

[0035] Preferably, the main body mold 10 and the adapter mold 20 are fittings made of aluminum alloy or stainless steel.

[0036] Embodiment Two

[0037] Please refer to Figures 4 - 6 As shown, the present application provides a pipe winding machine, including the carbon fiber tube mold 1 described above, a pipe pressing shaft 30, and a pipe winding shaft 31. The pipe pressing shaft 30 is arranged on a lifting device 32. The pipe pressing shaft 30 and the pipe winding shaft 31 are arranged in a triangular shape, and a pipe winding channel is formed between the pipe pressing shaft 30 and the pipe winding shaft 31. The carbon fiber tube mold 1 is rotatably passed through this pipe winding channel. The pipe pressing shaft 30, the pipe winding shaft 31, and the carbon fiber tube mold 1 can all rotate, and they are driven to rotate by a motor. During production, the pipe pressing shaft 30 and the pipe winding shaft 31 press on the carbon fiber tube mold 1 simultaneously, so that the carbon fiber tube is evenly stressed and the quality is more guaranteed.

[0038] Preferably, the pipe winding shaft 31 is arranged on a workbench 35. The lifting device 32 includes a servo linear module. The output end of the servo linear module is connected to the mounting bracket 34 of the pipe pressing shaft 30, and this mounting bracket 34 can slide up and down on a frame 33. As the thickness of the carbon fiber tube on the carbon fiber tube mold 1 increases, the servo linear module drives the pipe pressing shaft 30 to rise, and the stress on the carbon fiber tube is controlled within a more reasonable range.

[0039] During production, align the length direction of the carbon fiber prepreg with the first scale line and the second scale line 23 in the length direction of the mold, and place it on the pipe winding machine for winding and banding. After completing the pipe winding, clamp the mold slot on the fixture of the oven, hang a weight on the hanging hole 14, and after curing according to the required process, clamp the groove 13 of the mold on the core removing machine to complete the mold demolding.

[0040] In summary, the design focus of the present utility model is that its main body mold 10 and several sections of adapter molds 20 are combined together, so that the overall length of the mold can be lengthened or shortened, and the versatility is better. If the mold is damaged, only the corresponding main body mold 10 / adapter mold 20 needs to be replaced during maintenance, which is very convenient to maintain, has a simple structure, and a low maintenance cost. The first scale line 12 and the second scale line 23 facilitate positioning the carbon fiber, and the groove 13 facilitates extracting the carbon fiber tube from the mold, making the demolding convenient. The mold is arranged vertically, and a weight is hung at the hanging hole 14, which is beneficial to improving the straightness of the carbon fiber pipe.
