  • Publication number: 20240133438
    Abstract: An electromechanical drive includes a motor, a rotational part rotatable by the motor about a rotational axis, and a braking device that can be actuated between a braking position and a released position, the braking device having a brake disc that rotates with the rotational part and a braking element that can be adjusted in the axial direction and acts on the brake disc in the braking position. The brake disc has an inner area, a friction surface area extending annularly around the rotational axis with a first friction surface formed on a first side of the brake disc, and an intermediate area extending between the friction surface area and the inner area around the rotational axis. A first mating surface is formed on the braking element, which mating surface faces the first friction surface and interacts with the first friction surface in the braking position.

  • Patent number: 11117175
    Abstract: A forming operation on a workpiece clamps the workpiece between a first clamping jaw with a first shaping edge, and an adjustable second clamping jaw with a second shaping edge so that a portion projects between the shaping edges and afterwards a bending edge of an adjustable bending bar is guided at a distance past the shaping edges, whereby the portion of the workpiece is angled away in relation to the part of the workpiece that is clamped between the clamping jaws. The bending edge is guided on angling along a straight path of movement of the bending edge, and after the bending edge has passed the shaping edges, the shaping edges are adjusted along an adjustment path which approaches the path of movement of the bending edge.
