The specific embodiment
As shown in Figure 1, the utility model comprises total body support frame 2, polytetrafluoroethylene (PTFE) guiding core pipe 3, pipe end heater 4, heating plate 5, seal mouth ring heater 6, polytetrafluoroethylene (PTFE) plunger tip 10, pushing plate 11, drive unit 12 and guide rod 13.
Total body support frame 2 is used for supporting whole closing device, and guide rod 13 is fixedly connected on total body support frame 2.
The heating part of closing device comprises pipe end heater 4, heating plate 5 and seal mouth ring heater 6, and the three is fixedlyed connected with nut 8 by bolt 7.
Polytetrafluoroethylene (PTFE) guiding core 3 is fixed together with pipe end heater 4, heating plate 5 and seal mouth ring heater 6 as shown in Figure 2.Polytetrafluoroethylene (PTFE) guiding core 3 outer circumference surfaces have 2 °～3 ° tapering, its outside diameter is consistent with the internal diameter of steel-plastics composite pipe 1, prevent that steel-plastics composite pipe 1 is heated evenly with the pipe end face that guarantees steel-plastics composite pipe 1 than large deviation in axial the appearance with pipe end heater 4 when heating.
Pipe end heater 4 as shown in Figure 3, be used for heating inside and outside two end faces of steel-plastics composite pipe, on its end face, have trapezoidal endless groove 41, the degree of depth of trapezoidal endless groove 41 is not less than 5mm, bottom land is wider than more than the enhancing metal layer thickness 1mm of steel-plastics composite pipe 1, two sloping platform surface roughnesses are not less than 1.6, the surface-coated polytetrafluoroethylene (PTFE), and the sloping platform angle of medial and lateral is between 45～65 °.Trapezoidal endless groove 41 contacts with inside and outside two end faces of steel-plastics composite pipe.Trapezoidal endless groove sloping platform angle makes pipe end heater 4 when the heating steel-plastics composite pipe, and flange appears in outer wall, but does not influence butt joint, and there is the inclined-plane in inwall, can not provide " material source ".
