In order to solve the technical problem of above-mentioned existence, present invention employs following scheme:
A kind of electromagnetic induction heating coil, it is characterized in that: comprise left side arc induction coil (51) and right side arc induction coil (52), fixed plastics connector (4 is formed between left side arc induction coil (51) and right side arc induction coil, 10) grasping part (56), a link on left side arc induction coil (51) and right side arc induction coil (52) is hinged by bearing pin (54), another link on left side arc induction coil (51) and right side arc induction coil (52) is provided with plastic fastening (4, 10) opening of grasping part (56) is entered, the size of described opening is swayed by left side arc induction coil (51) or right side arc induction coil (52) and is adjusted, electromagnetic induction heating coil is connected with welding plastic tubes power supply by terminals (55).
Further, the opening between left side arc induction coil (51) and right side arc induction coil (52) is also connected with fixing snap close (53).
This electromagnetic induction heating coil has following beneficial effect:
(1) plastic fastening between the plastic fastening between thermoplastic plastic pipe or steel-plastic composite pipe is placed in its grasping part by the present invention, by electromagnetic controller, magnetic energy is converted to heat energy, and by the metal in plastic fastening or the metal in composite pipe by heat conduction to plastic fastening, thus the pattern of the rear grafting of tradition first heating is changed, improve the efficiency of connection, reduce cost of labor simultaneously.
(2) the present invention adopts and first connects the pattern heated again, and the heating junction that it also avoid tubing is directly exposed in air, reduces the generation of oxidation, keeps the intensity of tubing junction.
(3) the present invention is owing to adopting wire netting aperture layer, and wire netting aperture layer generate heat and tubing after making hot melt can carry out welding through wire netting aperture layer and plastic fastening, and two tubing are then by making it connection with the plastic fastening of wire netting aperture layer.
