Bolt can make plastic tube realize the structure for being similar to flanged joint, and connection is more secured, and sealing effect is more preferable；Make plastics at present
The mode of pipe flange after heating and softening, utilizes taper die the most commonly used is using taper die to heat plastics pipe port
Taper, the mold is pushed to inside of plastic tubes, to make plastic tube flange.
Existing flanger structure includes mainly clamping device (for plastic tube to be clamped), and the mold with high temperature,
The shape of mold is frustum of a cone column.When flange, the nose cone of mold feed motion, mold is inserted into plastics in-pipe, plastics
Pipe is softened by the heating of mold, plastic deformation occurs under the promotion of the mold of cone, plastic tube nozzle is bent outwardly
Flange is realized in deformation.But since mold can only heat the inner wall of plastic tube, for the thicker plastics of some tube walls
Pipe, the inner and outer wall uneven heating of mold plastic conduit when flange cause outer wall when flange not soften, by force
Feeding mold may be easy to cause nozzle fracture, and flange failure even causes plastic tube to scrap.
