Abstract

PURPOSE: To obtain an impact unit featuring the high response to the temperature by using the ferromagnetic substance the easy-to-magnetize axis direction of which varies by the temperature for the magnetic path switching means.
CONSTITUTION: Magnetic path switching component 2 the easy-to-magnetize axis direction of which varies by the temperature and composed of the rare earth cobalt alloy is provided at the common intersection of parallel magnetic circuit 1 consisting of magnetic paths 11 and 12 using the iron core of the soft magnetic substance or the like. And input coil 3 is turned round magnetic path 13, and output coils 4 and 5 are turned round magnetic paths 11 and 12 respectively. Then electromagnets 6 and 7 which are opposing to each other holding movable armature 8 holding impact hammer 14 between are connected to coils 4 and 5. Furthermore, such constitution is secured in that the power is supplied via armature 8 to heating wire 10 attached to component 2 when the contact is secured between magnet 6 and armature 8. As a result, the impact caused by hammer 14 can be repeated in the automatic and continuous way.
