Automotive pipeline and manufacture method thereof

Abstract

The invention relates to an automotive pipeline which is made from a nylon material. The automotive pipeline comprises 0.5% of plasticizer, 0.8% of fire retardant and 0.6% of heat stabilizer. The automotive pipeline is characterized by further comprising 5% of glass beads and 0.5% of silicone. The invention further relates to a manufacture method of the automotive pipeline. The method comprises the following steps of: putting a pipe into a mould and fixing; blocking two ends of the pipe by a choke plug with holes; heating and forming by using steam; sizing by means of water cooling; and finally blowing to be dry by compressed air to obtain the formed automotive pipeline. The phenomena of deformation and springback of the nylon pipeline in the process of forming can be avoided, so that the production efficiency can be improved, the energy efficiency in the process of forming can be reduced, and the forming quality of the pipe can be guaranteed.

Description

technical field [0001] The invention relates to a pipeline used in automobiles, in particular to a steam-formed vehicle pipeline and a preparation method thereof. It belongs to the technical field of auto parts. Background technique [0002] At present, nylon tubes have been used in the automotive industry to replace metal tubes. They are used on various pipelines of automobiles. During processing, thermoplastic tubes such as nylon tubes often need to be formed into specific pipeline shapes to meet the space requirements for pipeline installation. When the thermoplastic tube is formed, the thermoplastic tube is usually fixed in a mold with a specific shape, and the straight tube is shaped into a specific shape corresponding to the mold by using the thermoplasticity of the tube by heating. [0003] The traditional pipe forming process is realized by baking forming, and the forming oven is used for forming. Using a forming oven to form thermoplastic tubes is suitable for pro...

AI Technical Summary

Problems solved by technology

Using a forming oven to form thermoplastic tubes is suitable for prototypes and small batches of tubes, but for large batches of thermoplastic tubes, the forming time is longer and the power consumption is high, which not only wastes energy, but also reduced productivity

In order to make up for this defect as much as possible, ten or more sets of molds are generally made and baked at the same time, but the shape of the tubes formed by using more molds may not be able to achieve the same effect, resulting in relative quality problems
