Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene pipe processing, in particular to a steel-lined polytetrafluoroethylene pipe flanging workbench. Background Art

[0002] Steel-lined PTFE pipe is an essential and important component in chemical corrosion protection, and is used in large quantities. The sealing surface flanging is a key process in the production process. The existing process method is to first place the steel-lined PTFE pipe in the mold, leaving a small length outside, heat the flanging mold to a certain temperature, and then press the mold on the exposed section of the PTFE pipe to soften it and extend it, and then use the shaping mold to compress it and cool it to shape it.

[0003] Among them, the current technology has a patent announcement number of CN217968404U, which proposes a steel-lined PTFE tube flanging work frame, including a work frame, a positioning plate, a worm, a worm wheel, a push rod, a positioning rod, a slide groove and a steel-lined PTFE tube body. The beneficial effect of the utility model is: the steel-lined PTFE tube body passes through two positioning plates, and the worms on the two positioning plates are rotated in sequence. The rotation of the worm will drive the worm wheel to rotate, and then the worm wheel drives the push rod thereon to rotate together, so that the push rod hits the inner wall of the slide groove of the positioning rod and drives the positioning rod to rotate, so that one end of the plurality of positioning rods rotates close to the steel-lined PTFE tube body and hits the steel-lined PTFE tube body.

[0004] It fixes the steel-lined PTFE tube body by friction, which is convenient for fixing steel-lined PTFE tube bodies of different sizes. Then, it is only necessary to heat the conical heating flanging mechanism and press it with a section of the steel-lined PTFE tube body exposed on the side of the positioning plate, so that it will extend after being softened by heat. It is difficult to perform precise flanging on the PTFE tube, and the PTFE tube may be damaged during the flanging process. Utility Model Content
