Abstract: An arrangement on a coordinate table of a processing machine for driving a carriage movable in an X-direction has a displacing device with a ball screw nut carried by a carriage and a ball screw cooperating with the ball screw nut and having two ends, two end supports each provided at the respective end of the ball screw and being stationary relative to the carriage, two additional supports provided for said ball screw and arranged on the carriage at opposite sides of the nut and movable relative to the carriage in direction of its movement, two stationary abutments each arranged at a respective one of the ends of the carriage and limiting a movement stroke of a respective one of the additional supports when the latter abut against the respective stationary abutment, two releasable abutment locks arranged so that each of the additional supports is arrested during abutment against a respective one of the stationary abutments and released during running against a respective one of the end supports because of th

Abstract: A cutting press for treating plate-shaped workpieces includes a coordinate table and a stationary support which surrounds the working area of a cutting tool. A central workpiece support is mounted on the coordinate table for movement in lateral guides of the latter toward and away from the stationary support independently of the movement of the coordinate table, so as to open and close a discharge opening between itself and the stationary support. The central workpieces support includes a plurality of elongated support elements extending transversely of the direction of movement of the central workpiece support in the lateral guides and articulately connected in series to one another. Driving units are provided which act on the ends of the movable central workpiece support for moving the same relative to the coordinate table.

Abstract: A matrix releasably mounted on an elongated matrix shoe is pressed by end faces of a pair of spring-biased clamping levers tiltable at outer ends about axes parallel to the axis of the matrix against an upwardly extending abutment face of the shoe, and a tool including a slide movable between the clamping levers to spread the same apart and having a withdrawal lever tiltable above the slide about an axis extending transverse to the latter and carrying a pin arranged to enter a catch bore provided in the matrix for withdrawing the matrix in the direction of the elongation of the shoe from the latter.

Abstract: An arrangement in a revolving press for withdrawing or inserting a tool holder carrying a punch from and into an opening in a turntable of the press when the tool holder turns with the turntable to an exchange position. The tool holder is in the exchange position temporarily held by a slide engaging a tool holder head projecting upwardly from the tool holder. A guide member substantially aligned with the axis of the tool holder in the exchange position carries at its lower end a gripping claw in such a manner that when the guide member is lowered while the slide is withdrawn, the claw will engage the tool holder head. Thereafter the guide member is raised, moving the tool holder out of the opening in the turntable and finally the tool holder is manually removed from the guide member so that a new punch can be mounted thereon, whereafter the tool holder is moved in reverse direction back into the opening of the turntable.

Abstract: 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.

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.
