Abstract

An embodiment of the invention provides an electromagnetic-heating welding jig for steel-plastic composite pipes. The electromagnetic-heating welding jig comprises an annular jacket, a magnet exciting coil and an electromagnetic-heating control circuit; the annular jacket comprises a first semi-annular jacket body and a second semi-annular jacket body; the first semi-annular jacket body comprises a first semi-annular jacket body hoop and a first semi-annular magnetic exciting ring fixing part connected with the first semi-annular jacket body hoop while the second semi-annular jacket body comprises a second semi-annular jacket body hoop and a second semi-annular magnetic exciting coil fixing part connected with the second semi-annular jacket body hoop; the two semi-annular jacket bodies are connected in a hinged manner at one ends of the two semi-annular jacket body hoops and are connected in a closed manner through a first locking mechanism at the other ends of the two semi-annular jacket body hoops; threaded grooves are formed outside the annular magnetic exciting ring fixing parts; the magnetic coil is formed by winding of a Litz wire and is fixed in the threaded grooves; two ends of the magnetic coil are electrically connected with the electromagnetic-heating control circuit.

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...
