Abstract (en)
[origin: EP1867404A1] In a closing machine (1) for closing an open end of a work piece (9) by pressing a die (4) heated by a high frequency heating device (2) against the work piece (9) rotating about an axial center, the die (4) comprises a die main body (601) which contacts the work piece (9) and a holder (611) which surrounds the die main body (601). The die main body (601) is formed from cemented carbide whereas the holder (611) is formed from a steel material. The holder (611) is subjected to induction heating by the high-frequency heating device (2), whereas the die main body (601) is heated by heat transfer from the holder (611).
