Abstract

The invention discloses polytetrafluoroethylene extrusion tube forming equipment, and relates to the technical field of polytetrafluoroethylene extrusion tubes. The equipment aims to solve the problemthat existing extrusion tubes are low in strength right after extrusion, deformation is easily caused by external actions and the extrusion quality is affected. An extrusion nose is installed at oneend of an extrusion cylinder barrel; a cylinder barrel core bar is arranged inside the extrusion cylinder barrel; an outer mold core seat is arranged on the inside the extrusion nose; an outer mold core is arranged on the inside of the outer mold core seat; an inner mold core is arranged on the inside of the outer mold core; a sealing barrel cover is arranged at the upper end of the extrusion cylinder barrel; a plunger push plate is installed on the inside of the extrusion cylinder barrel; a multistage air cylinder is arranged at one end of the plunger push plate; a fixed frame is installed onthe outer part of the multistage air cylinder; the fixed frame and the multistage air cylinder are positioned on the outer part of the extrusion cylinder barrel; the multistage air cylinder and the fixed frame are connected with the extrusion cylinder barrel via screws; and sealing clamp rings are arranged on the outer part of the extrusion cylinder barrel and of the extrusion nose.

Description

technical field [0001] The invention relates to the technical field of polytetrafluoroethylene extruded pipes, in particular to a polytetrafluoroethylene extruded pipe forming equipment. Background technique [0002] The PTFE pipe is made of high-quality plunger extruded pipe, and the special processing technology is used to make the steel pipe and the plastic pipe tightly combined, which can withstand positive pressure of 1.6 MPa and negative pressure of 77 kPa; It can be used normally between minus 60 degrees Celsius and 260 degrees Celsius, and has reliable and excellent corrosion resistance. Transporting highly corrosive gases and liquids at high temperatures cannot be replaced by other pipelines. Polytetrafluoroethylene (PTFE) has excellent chemical stability and can withstand all strong acids, strong alkalis, strong oxidants, and various organic solvents. PTFE is a good anti-friction and self-lubricating material, its static friction coefficient is smaller than the dy...
