Fiber winding device of pressure vessel and production method thereof

Abstract

The invention provides a fiber winding device of a pressure vessel and a method. The device comprises a pressure vessel clamping device, an annular winding device, a spiral winding device and a control device. The pressure vessel clamping device drives a pressure vessel inner container to move and rotate simultaneously to penetrate through the spiral winding device to complete spiral winding. And then the pressure container inner container is kept static, the annular winding device moves to penetrate through the pressure container inner container to complete annular winding, and the control device controls the winding process to be automatically carried out. According to the device, automation of the whole fiber winding process can be achieved; and meanwhile, a novel multi-bundle winding technology is provided, the undesirable phenomenon of single-bundle winding is overcome, on the premise that the performance of the pressure vessel is guaranteed, the use quantity of carbon fiber materials is reduced, and then the production cost of the pressure vessel is reduced. And the storage pressure and the production efficiency of the pressure container are improved.

Description

technical field [0001] The invention relates to a fiber winding device and a production method for a pressure vessel. Background technique [0002] Pressure vessels are widely used in many fields, such as industry, medical treatment, automobile and other fields. Taking the automobile field as an example, the national plan regards hydrogen fuel cell vehicles as one of the key development directions, and pressure vessels are one of the key links for the widespread popularization of hydrogen energy. At present, high-pressure hydrogen storage containers are mainly divided into Type III containers (metal liner) and Type IV containers (resin liner). Carbon fiber is wound on the outer surface of the container as the main pressure-bearing layer, while ensuring the safety performance of the container. In the production and processing of pressure vessels, single-bundle winding is the main method. This method will cause fiber stacking, crossing, and uneven winding, resulting in local ...

AI Technical Summary

Problems solved by technology

In the production and processing of pressure vessels, single-bundle winding is the main method. This method will cause fiber stacking, crossing, and uneven winding, resulting in local stress concentration of the pressure vessel, which seriously restricts the safety performance of the vessel, and the entire production process cannot be realized. Fully automated, low production efficiency
