ELECTRIC HEMMING PRESS
A hemming press (10) that includes a crown (14) and a base plate (12) separated by four corner posts (16-22). A press ram (30) is slidably mounted on the posts (16-22) between the crown (14) and base plate (12). A first die (34) is mounted to a lower surface (32) of the press ram (30) and a second d...

| description | A hemming press (10) that includes a crown (14) and a base plate (12) separated by four corner posts (16-22). A press ram (30) is slidably mounted on the posts (16-22) between the crown (14) and base plate (12). A first die (34) is mounted to a lower surface (32) of the press ram (30) and a second die (36) is mounted to an upper surface (24) of the base plate (12). Workpieces to be hemmed are placed in the second die (36), and the press ram (30) is moved from an upper home position to a lower hem position to perform the hemming process. Pre-hemming and final hemming steps are performed by one continuous stroke of the press ram (30). A pre-hem pressure is provided to the press ram (30) by at least one electric servomotor (40, 42) and roller screw assembly, and a final hem pressure is provided to the press ram (30) by at least one hydraulic actuator (50, 52, 54, 56).

L'invention concerne une presse de rabattage qui comprend un chapiteau et une plaque de base séparés par quatre poteaux d'angle. Un coulisseau est monté coulissant sur les poteaux entre le chapiteau et la plaque de base. Une première matrice est montée sur une surface inférieure du coulisseau et une seconde matrice est montée sur une surface supérieure de la plaque de base. Les pièces à rabattre sont placées dans la seconde matrice, puis le coulisseau passe d'une position initiale supérieure à une position de rabattage inférieure afin d'effectuer le rabattage. Les étapes de pré-rabattage et de rabattage final sont effectuées par une course continue du coulisseau. Au moins un servomoteur électrique et un ensemble vis à rouleaux exercent une pression de pré-rabattage sur le coulisseau et au moins un actionneur hydraulique exerce une pression finale de rabattage |
