    摘要： A cutting device includes a cutting member 70 having a pair of cutting parts 71 and 73 rotatable around a common shaft 75 in a mutually approaching direction and / or in a mutually separating direction, and a driving unit (for example, a motor 16, a battery 17, and a hydraulic pump 20) that operates the cutting member 70 so that each of the cutting parts 71 and 73 rotates around the shaft 75 in the mutually approaching direction and / or in the mutually separating direction. Each of the cutting parts 71 and 73 of the cutting member 70 has an opposing blade part 72 and 74 respectively. The convex portions 72b and 74b have a shape such that convex portions 72b and 74b first contact the cylindrical rod when each of the cutting parts 71 and 73 rotates around the shaft 75 to move in the mutually approaching direction.

    摘要： The invention is concerned with a shearing apparatus (120) comprising:
    a housing (122) comprising a first side wall, a second side wall, a top wall (150), and a bottom wall (152), the walls forming a stationary die pocket (142) and a movable die pocket (144) therein, the movable die pocket (144) overlapping the stationary die pocket (142) in a longitudinal direction, a first passageway extending though the first side wall and in communication with the stationary die pocket, and a second passageway extending though the second side wall and in communication with the movable die pocket, the first and second passageways being aligned in a direction angled relative to the longitudinal axis;
    a force transmitting apparatus (126) mounted within the housing (122);
    a stationary die (22) seated in the stationary die pocket (142) in the housing, the stationary die (22) being non-movable relative to the housing (122) when seated in the stationary die pocket (142), the stationary die having a cutout therein configured to cut a workpiece, the stationary die being capable of being removed from the housing;
    a movable die (22') seated in the movable die pocket (144) in the housing (122);
    a die engaging mechanism between the force transmitting apparatus and the movable die, the die engaging mechanism configured to be released to decouple the force transmitting apparatus and the movable die;
    an end stop assembly (124) attached to the housing (122) and configured to selectively close an end of the movable die pocket; and
    wherein the movable die (22') is engaged with the force transmitting apparatus (126) and movable longitudinally relative to the stationary die and the housing when moved by the force transmitting apparatus, the movable die having a cutout therein configured to cut a workpiece, the movable die being capable of being removed from the housing.

    摘要： La présente invention concerne une lame de cisaillage (1) destinée à être positionnée dans un logement (5) d'une presse, ledit logement (5) comprenant une paroi inférieure, une paroi arrière et deux parois latérales pour presse-cisaille dans laquelle la lame (1) comprend une face inférieure (21), une face arrière (15) et deux faces latérales (17, 19) complémentaires respectivement de la paroi inférieure, de la paroi arrière et des parois latérales du logement (5), la lame (1) comprenant également une face avant (13) et une face supérieure (23) et une arête de cisaillage (A1) à l'interface entre la face avant (13) et la face supérieure (23),
    dans laquelle la lame (1) comprend un ou plusieurs blocs (B1, B2, B3) adjacents dans le sens de l'arête de cisaillage (A1),
    au moins un bloc (B1), dit bloc pivot, comprenant une face avant (13) plus longue, dans le sens de l'arête de cisaillage (A1), que sa face arrière (15) et une face latérale inclinée (17, 19, 45, 47) de sorte que pour tout point de la face latérale inclinée (17, 19, 45, 47), l'inclinaison, par rapport à une direction orthogonale à la face avant (13), est supérieure ou égale à la tangente au cercle passant par ce point et dont le centre est la jonction entre la face avant (13) et la face latérale (17, 19) du bloc opposée à ladite face latérale inclinée (17, 19, 45, 47).

    摘要： A piercing tip (18) for a shear (10) is disclosed. The piercing tip may have a first part (20) configured to be secured to a jaw (14) of the shear. The first part may have a first planar surface (48) configured to abut a first side surface (34) of the jaw. The piercing tip may also have a second part (22) configured to be secured to the jaw and the first part. The second part may have a planar portion (58) including an inner surface (62) configured to abut a second side surface (36) of the jaw. The second part may also have a projecting portion (60) including an upper surface (68) configured to abut a lower surface of the jaw (38), and a projecting surface (70) abutting the first planar surface of the first part.
