Description

Technical Field

[0001] The invention relates to the technical field of bellows processing, in particular to a joint assembly device for Teflon bellows. Background Art

[0002] Polytetrafluoroethylene, also known as Teflon, commonly known as the "King of Plastics", is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. Teflon bellows are special tubes made by extruding and sintering polytetrafluoroethylene materials, followed by drying, high-temperature sintering, and shaping. The bellows are connected to the quick-connector with an interference fit during use. During the connection process, the bellows needs to be limited and fixed to facilitate docking between the bellows and the quick-connector. Existing bellows and quick-connectors are generally assembled manually, with one hand holding the bellows and the other holding the quick-connector. This is not only inefficient, but also wastes labor, has unstable quality, and poor product consistency. Improper assembly can easily cause product leakage, and the after-sales repair and disassembly costs are very high.

[0003] At the same time, after installing the joint assembly on the bellows, it is necessary to flanging the two ends of the bellows to prevent the joint from falling off. However, the existing bellows are manually installed and processed during the installation of the joint and the flanging. Especially when flanging, the person manually holds one end of the bellows close to the mold, so that the bellows is heated and flanging. As a result, the product consistency is relatively poor in actual use. If the assembly is not in place, it is easy to cause product leakage. In addition, manual processing is performed one by one, which makes the processing efficiency slow.

[0004] Based on this, a joint assembly device for Teflon bellows is now provided, which can eliminate the disadvantages of the existing device. Summary of the Invention
