It is axially coupled to a fixed lever 7 fixed to a driving case 8 via a fulcrum shaft 6 so as to perform a seesaw motion. One end of a crimp terminal crimping die 12 is axially coupled to the eccentric cylindrical cam 4' side of the swing lever 5 and the opposite tip with the fulcrum shaft as the center, through a shaft 9, and the swing lever 5 is also pivoted. The tip of the fixed lever 7 corresponding to the tip of the die 12 is also axially connected to the other end of the die 12 by a shaft 9'. Reference numeral 10 denotes a fixed shaft for fixing the lever portion of the die 12, and the positional relationship of the lever portion of the die 12 is firmly maintained by the fixing plate 11.

圧着用ダイスを簡単に開閉することが出来る。 Since the pinion 3 is meshed with the power gear 4, the power gear 4 rotates and rotates the eccentric cylindrical cam 4' formed on the side surface thereof. Swing lever 5
operates following the swinging motion of the eccentric cylindrical cam 4' from the bottom dead center side toward the top dead center, and the fulcrum shaft 6
Seesaw movement centered on. As the swinging lever 5 makes a see-saw movement, the crimp terminal crimping die 12 is connected to the tip of the swinging lever 5 opposite to the eccentric cylindrical cam 4' about the fulcrum shaft 6 by a shaft 9. operates between the tip of the swinging lever 5 and the connecting portion of the shaft 9' at the tip of the corresponding fixed lever 7, and the lever portion of the die 12 engages and presses around the fixed shaft 10. will occur. Swing lever 5
Since it is integrally connected by the corresponding fixed lever 7 and the fulcrum shaft 6, there are few friction points, and the loss of transmitted power can be reduced as much as possible. Also,
The fixed lever is fixed to the prime mover case 8, and the fulcrum shaft 6 is provided on the fixed lever, so the movement of the swinging lever 5 depends on the shaft support of the power gear 4 provided inside the prime mover case. If the relationship between the supporting part and the fulcrum shaft of the fixed lever is manufactured accurately, a constant assembly relationship can be maintained at all times, and a highly accurate mechanism can be easily assembled. In addition, the swing lever 5 is connected only when the eccentric cylindrical cam 4' moves from the bottom dead center to the top dead center. When the eccentric cam 4' is in the bottom dead center region, the power transmission section 5' of the swing lever 5 is a free end that is not restrained by the eccentric cylindrical cam 4'. Therefore, the rocking lever can be made a light see-saw movement from the outside.
The crimping die can be easily opened and closed.
