Title: INDUCTION HARDENING DEVICE AND ASSEMBLY
Abstract:
Induction hardening device (1) for hardening a metallic workpiece (2). The device (1) comprises at least one inductor core (3), an insulator block (4) that presents an outer peripheral surface (5). The insulator block (4) at least partly encloses the at least one inductor core (3) such that a magnetic flow (6) generated from the at least one inductor core (3) is directed in a specific direction towards the workpiece (2). Furthermore, the insulator block (4) presents at least one connecting means (7) on the outer peripheral surface (5), wherein the connecting means (7) is meant to be able to connect to another induction hardening device. Furthermore, an induction hardening assembly (10) is disclosed, comprising at least two induction hardening devices (1), wherein the devices (1) are connected via their connecting means (7).
