Abstract

The invention provides an electromagnetic heating fusion welding fixture for steel-plastic composite pipe. The electromagnetic heating fusion welding fixture comprises an annular housing, a handle connected with the lower part of the annular housing, a magnet exciting coil and an electromagnetic heating control circuit; the magnet exciting coil and the electromagnetic heating control circuit are fixed in the annular housing; the magnet exciting coil is electrically connected with the electromagnetic heating control circuit through a wire; the annular housing comprises a first semicircular housing part and a second semicircular housing part; one end of the first semicircular housing part is connected with one end of the second semicircular housing part in a hinged manner; the other end of the first semicircular housing part is connected with the other end of the second semicircular housing part through a first locking mechanism in a closed manner; the magnet exciting coil of the electromagnetic heating fusion welding fixture comprises a litz wire fixed to the inner wall of the annular housing; and the two ends of the litz wire are connected with a first contact connecting piece and a second contact connecting piece respectively. According to the electromagnetic heating fusion welding fixture by the inventor, after the conventional semicircular metal body is replaced by the litz wire to act as the magnet exciting coil, the electromagnetic heating permeability is good, the electromagnetic heating fusion welding fixture is not prone to heat and can be continuously used, and an alternating magnetic field generated around the electromagnetic heating fusion welding fixture is uniform.

Description

technical field [0001] The invention relates to the field of processing steel-plastic composite pipes, in particular to an electromagnetic heating welding fixture for steel-plastic composite pipes. Background technique [0002] Steel-plastic composite pipes are widely used in water and air circulation systems in urban residential buildings because they have both the high strength of metal pipes and the corrosion resistance of plastic pipes. [0003] In the prior art, the connection methods of the steel-plastic composite pipe mainly include heat-melting and then socket connection, mechanical connection and electromagnetic heating connection. Among them, the method of hot-melting first and then socket connection, that is, heating the male and female mold sleeves through a heating plate, and then inserting the pipe joints and pipes (steel-plastic composite pipes to be connected with the pipe joints) into the male and female mold sleeves, so that the pipe joints and pipes After...
