Abstract

The invention provides a PEEK pipeline hot bending production process and a hot bending die, and relates to the technical field of aviation pipeline hot bending production processes. The PEEK pipelinehot bending production process is a process in which a PEEK pipe is formed by injection molding of PEEK granules, and then the PEEK pipe is bent while being heated. The process comprises the following steps that a PEEK pipeline is arranged on a hot bending die; and the hot bending die is heated, and after the PEEK pipeline reaches a preset temperature, the hot bending die is driven by a bending machine to bend the PEEK pipeline. The PEEK pipeline hot bending production process is used for bending the PEEK pipeline.

Description

technical field [0001] The invention relates to the technical field of hot-bending production technology of aviation pipelines, in particular to a production technology of hot-bending PEEK pipelines and a hot-bending mold. Background technique [0002] At present, the pipelines used in the anti-icing and sewage systems in the domestic aviation field are mostly metal such as titanium tubes and aluminum alloy tubes, which are heavy and easy to corrode. Therefore, the lightweight pipeline is a bottleneck that urgently needs to be broken through in production. PEEK material has the advantages of light weight, high strength, wear resistance, corrosion resistance and high temperature resistance. On the premise of satisfying the function of the pipeline, the PEEK pipeline maintains sufficient flexibility at the same time. It is a pipeline with light weight and good heat resistance, which is conducive to the lightweight of the aircraft. [0003] However, the PEEK hot bending proce...
