Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a carbon material tooling device for electric induction heating. Background Art

[0002] When producing motor rotors, there are three processes for assembling support tubes, rotor cores, and magnetic rings, and the assembly method is hot assembly.
