摘要： A drawing arrangement for producing drawn formations in sheet-shaped workpieces includes a lower tool having a supporting surface for the workpieces and a recess which opens onto the supporting surface, and an upper tool having a female die and movable toward and away from the lower tool for confining a region of the workpiece between itself and the supporting surface. A mandrel is mounted in the recess of the lower tool for movement between a retracted position in which it is fully accommodated in the recess and thus does not project beyond the supporting surface and form an obstruction to the movement of the workpiece, and an extended position in which it penetrates into the female die and forms the drawn formation in the workpiece. The punch is mountd on an actuating member which has a lower contact surface, and the movement of the actuating member is achieved by a lifting device which has an operating member movable toward and out of contact with the contact surface, and a spring which urges the actuating member toward its retracted position. During the retraction movement, the punch itself acts as a stripping tool for the workpiece. A descending chute can be interposed between the actuating and operating members and has a pivotable section movable out of the path of movement of the operating member. The operating member may move at different speeds during approach to the actuating member and thereafter.

摘要： A stripper arrangement for a tool includes a stripper, a stripper shoe mounted on a lower side of a tool holder of a tool and having an opening for receiving the stripper so that the latter can be inserted into the opening by movement in a plane transverse to the axis of the tool, a retaining member displaceable between an operative position in which it engages and retains the stripper and an inoperative position in which it does not engage the stripper, and a spring urging the retaining member to the operative position. An auxiliary tool for replacing the stripper has an abutment face arranged to abut against a lower side of the stripper, and a projection extending toward the stripper and arranged to displace the retaining member to its inoperative position so as to disengage the retaining member from the stripper. The auxiliary tool may also clamp the stripper for removal or insertion of the latter.

摘要： A cutting press equipped for handling and treating or working plate-shaped workpieces or articles, especially of sheet metal, includes at least one cutting tool which is driven from a main drive of the machine through transmission components and its own driving arrangement. An additional severing arrangement is mounted on the same machine frame and is equipped with its own driving arrangement, the transmission members being selectively coupleable with the cutting tool and with the severing arrangement. The machine further includes a coordinate table for advancing the respective workpiece. An entraining arrangement is provided at the part of the machine frame which is associated with the severing arrangement and at the region of the workpiece which is free from the severing tools. The entraining arrangement is arranged above a support surface for the workpiece which extends in the same plane as the support surface of the coordinate table and is lowerable toward the workpiece. The entraining arrangement is operative for transporting the respective workpiece from the severing arrangement to a following conveying arrangement.
