Description

Technical Field

[0001] The utility model relates to the technical field of pipe production, in particular to a polytetrafluoroethylene pipe forming device. Background Art

[0002] Polytetrafluoroethylene is a synthetic polymer material with excellent chemical stability. It is resistant to all strong acids, strong alkalis, strong oxidants, and does not react with various organic solvents. In addition, polytetrafluoroethylene also has excellent aging resistance, non-stickiness and non-flammability. These characteristics make polytetrafluoroethylene pipes have excellent performance in high temperature and strong corrosive environments.

[0003] According to the publication number CN215703872U, a polytetrafluoroethylene tube forming device is disclosed, in which a forming mechanism is fixedly installed in the middle of the top of the mounting table, and the material is injected into the feeding box by opening the sealing cover, and the piston is squeezed by the first hydraulic rod to make the material preliminarily formed by the inner mold and the outer mold. After the material is preliminarily formed, it enters the heating mechanism for shaping, and the internal temperature of the heating box is increased by heating the heating wire, and the temperature of the heating box is transferred to the heat conducting plate through the fixed connection between the heating box and the heat conducting plate, and the outer mold is embedded and installed in the heat conducting plate, so that the heat conducting plate transfers the temperature of the heating box to the outer mold inside the heat conducting plate, and then transfers the heat to the preliminarily formed material to shape the material, and the feeding box is set to improve the efficiency of raw material transportation, and the temperature of the heating box is evenly transferred to the outer mold through the heat conducting plate, so that the polytetrafluoroethylene tube is evenly heated and the heating efficiency is improved.

[0004] However, the above device still has shortcomings. The temperature is increased by using a heat conduction plate to form the polytetrafluoroethylene tube, and then it is cooled. However, there are shortcomings in the feeding process. The raw materials directly enter the feeding box, which may cause the feeding box to be blocked. Secondly, the raw materials will accumulate inside the feeding box. The piston directly pushes the feeding box, which will cause the raw materials to accumulate at the bottom, affecting the feeding effect to the feed port. Utility Model Content
