Abstract
(EN)
A punch apparatus (10) includes a drive unit (18) and a driving force transmission mechanism (20) that transmits a driving force output by the drive unit (18) to a rod (16). In the driving force transmission mechanism (20), a cam groove (102) is formed in a cam block (34) connected to a piston rod (68), and a rotating roller (104), which is pivotally supported on a displacement body (100) connected to the rod (16), is inserted through the cam groove (102). The cam groove (102) has a first groove portion (112) and a second groove portion (114), which are inclined at predetermined angles of inclination with respect to the displacement direction of the cam block (34). When the rod (16) is made to descend toward the workpiece (W), the rotating roller (104) moves from the second groove portion (114) into the first groove portion (112), which has a small angle of inclination, whereby the driving force transmitted to the rod (16) is boosted.

La présente invention concerne un appareil à poinçon (10) qui comprend une unité d’entraînement (18) et un mécanisme de transmission de force d’entraînement (20) qui transmet une force d’entraînement générée par l’unité d’entraînement (18) à une tige (16). Dans le mécanisme de transmission de force d’entraînement (20), une rainure de came (102) est formée dans un bloc de came (34) raccordé à une tige de piston (68), et un rouleau rotatif (104), qui est soutenu de façon pivotante sur un corps de déplacement (100) raccordé à la tige (16), est inséré à travers la rainure de came (102). La rainure de came (102) a une première partie de rainure (112) et une deuxième partie de rainure (114), qui sont inclinées à des angles d’inclinaison prédéterminés par rapport à la direction de déplacement du bloc de came (34). Lorsque la tige (16) est amenée à descendre vers la pièce de fabrication (W), le rouleau rotatif (104) se déplace depuis la deuxième partie de rainure (114) dans la première partie de rainure (112), qui a un angle d’inclinaison faible, de sorte que la force d’entraînement transmise à la tige (16) soit amplifiée.
