<p>A heating device for heating objects, such as moulding tools for preheating them, removing rubber, to produce shrink fit operations and other treatments of objects (11, 12, 13) which consist at least partly of metal, the device comprising a core (2) of electric conductive material and at least a coil (3, 4) which is arranged around the core (2) and connected to a current source (20) to generate a magnetic field, the flux of which is intended to follow the said core. The core (2) has two poles (5, 6), between which a space (7) can exist to supply objects (11, 12, 13) to the device (1) for heating or treatment. One of the poles or both said poles (5, 6) are arranged to be able to be displaced in such a way that the core (2) can be closed or closed with an object (11, 12, 13) supplied and located between the poles (5, 6) for heating or treatment. A table (14) is arranged around the core (2) or one pole (6) of the core to unload the core (2) from loadings from an object (12, 13). The table (14), which comprises a non-conducting material, can be arranged vertically adjustable and show a frame consisting of partly electric conductive material partly non-conducting material.</p> |
