Description

Technical Field

[0001] The utility model relates to the technical field of processing fluoroplastic products, in particular to a device for processing a polytetrafluoroethylene tube into a flexible outer corrugated tube. Background Art

[0002] Polytetrafluoroethylene (PTFE) is a thermosetting engineering plastic that has the characteristics of other engineering plastics.

[0003] Generally, the forming process of fluoroplastic corrugated pipes is to shape the pipe material. In order to achieve continuous shaping operations, it is usually designed into spiral and equidistant parallel corrugated pipes. There are two types of shaping. The pipe material is heated by a spiral die, and then a spiral rod is screwed into the inside of the pipe material and manually wrapped around the outside of the pipe. The pipe material is heated by a spiral die, and both ends of the pipe material are sealed and inserted into the spiral die, and then blown into shape by air pressure.

[0004] The molding of spiral bellows requires preheating of the spiral film. Uneven temperature of the spiral mold is likely to occur during molding. Poor waveform or uneven thickness will occur due to uneven force between the spiral rod screwed into the spiral shaping machine and the manual spinning mold on the outside of the tube. The inflation blow molding process will cause the bellows to have poor waveform or uneven thickness. The annular bellows will have cleanliness problems, making them unsuitable for use in high-cleanliness processes. Utility Model Content
