Description
Technical Field
The utility model relates to the field of electric melting pipe fitting welding, in particular to an enhanced electromagnetic induction electric melting device.
Background
The traditional heating wire electric melting pipe fitting is characterized in that red copper wires, brass wires or other alloy wires with the diameter of 0.5-1.5 mm are pre-distributed on a melting welding area of the inner wall of the pipe fitting to serve as heating wires, after the pipe fitting and the pipe fitting are assembled, the heating wires are electrified to generate heat to melt plastics, so that the pipe fitting and the pipe fitting are bonded together to achieve the purpose of welding. And because the diameter of the heating wire is only 0.5-1.5 mm, the tensile strength of the heating wire is low, and the heating wire is easy to break and damage in the processes of production, assembly and welding, thereby increasing the rejection rate of products.
The technology effectively avoids the defects that the electric melting pipe fitting with the heating wire distributed on the inner wall is easy to short circuit, break the wire, have high rejection rate and the like, but the metal net embedded on the inner wall of the electric melting pipe fitting is incompatible with the main body plastic of the pipe fitting, and has a length of only a few centimeters to ten centimeters from the inner end of the pipe fitting to the pipe orifice, after welding, a gap can be generated between the plastic and the metal net, and liquid in the pipeline can extrude the pipe orifice along the gap between the main body plastic of the pipe fitting and the metal net under the pressure action, so that the leakage phenomenon of the pipeline can be generated.

The coil clamp solves the problem that temporary coils are not standard in winding, but one clamp can only correspond to one pipe fitting specification, and the cost is high. When the welding device is used, pipe fittings with various specifications need to be welded, and the welding device is inconvenient to carry, two ends of one pipe fitting need to be welded twice, and the welding time is prolonged; the hard plastic shell is easy to be broken and damaged in the carrying and construction process.
When the rigid plastic induction coil clamp is welded, the plastic shell of the rigid plastic induction coil clamp cannot resist high temperature and has basically the same melting temperature as a welded pipe fitting and a pipe fitting, the rigid plastic induction coil clamp can be in direct contact with the welded pipe fitting and the pipe fitting during welding, and when plastic on the pipe fitting and the pipe fitting is melted, the plastic shell of the induction coil begins to melt, so that the shell is directly damaged, and the service life of the induction coil clamp is greatly shortened.
