Polytetrafluoroethylene pipe flanging and hot-pressing device

Abstract

The invention belongs to the technical field of polytetrafluoroethylene pipe flanging, and particularly relates to a polytetrafluoroethylene pipe flanging hot-pressing device. The device comprises a base, a telescopic machine is arranged at the upper end of the base, a telescopic rod is connected to one end of the telescopic machine, a hot-pressing die is connected to one end of the telescopic rod, a limiting annular plate is arranged on one side of the hot-pressing die, a positioning column is arranged at the axis of the limiting annular plate, the back of the base is provided with a connecting bracket, a top plate is connected to one end of the connecting bracket, a connecting rod penetrating to the bottom end is arranged at the top of the top plate, a hydraulic telescopic machine is arranged at one end of the connecting rod, an upper fixing plate is arranged at the lower end of the top plate, and a lower fixing plate is arranged at the lower end of the upper fixing plate. By arranging the fixing plates, pipelines can be well fixed, operation becomes simple, and the pipelines with different lengths can be subjected to flanging treatment; and meanwhile, positioning column is arranged, the positioning column can be replaced according to the pipelines with different diameters, and therefore the equipment is multipurpose, and the flanging treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of tetrafluoro tube flanging, in particular to a tetrafluoro tube flanging hot pressing device. Background technique [0002] Existing technical background and application scenarios, the PTFE tube is extruded by a high-quality plunger, and a special processing technology is used to make the steel tube and the plastic tube tightly combined, which can withstand increased pressure, and is also stable at different temperatures. It is relatively stable, has reliable and excellent corrosion resistance, and can transport strong corrosive gas and liquid at high temperature, which cannot be replaced by other pipelines. It can be made of various special-shaped materials such as rods, pipes, films, bearings, gaskets, and valves. And parts are widely used in various fields. The existing flanging is mainly made of PTFE tube and then molded into a plate shape. [0003] There are the following problems: the larger the fla...
