Abstract: Workpieces are unloaded from a workpiece support of a sheet metal workpiece processing apparatus by positioning a blank sheet metal workpiece over a processed workpiece supported on a workpiece support, with the blank workpiece releasably held by a workpiece loader, activating a workpiece fixing device to engage an edge of the processed workpiece, and performing a relative sweeping movement between the workpiece fixing device and the workpiece support whereby the engaged processed workpiece is prevented from remaining on the workpiece support and is thereby unloaded. The workpiece fixing device is moved relative to the processed workpiece while the blank sheet metal workpiece is positioned over the processed workpiece.

Abstract: A tool for deburring cut edges on workpieces has a pressure body in the form of a rolling body, by means of which, as relative longitudinal movement of rolling body and workpiece takes place, pressure can be applied to the burr on the relevant cut edge in the direction towards the workpiece while the rolling body rolls along the cut edge. A machine for deburring cut edges on workpieces is provided with a tool of the above-mentioned kind. In the course of a process for deburring cut edges on workpieces, a rolling body is moved along the relevant cut edge with a rolling motion. In that movement, pressure is applied by means of the rolling body to the burr on the cut edge in the direction towards the workpiece.

Abstract: A plate workpiece processing machine includes a workpiece support, a tool punch holder, a tool die holder, a tool drive, multiple tool punches, and multiple tool dies. Various tool punches and tool dies have tool heads of differing heights. The tool punch holder is positionable based on the tool head height of a tool punch secured to the tool punch holder and/or the tool die holder is positionable based on the tool head height of a tool die secured to the tool die holder.

Abstract: For examining a metal sheet processing operation, a method includes scanning a detection beam along a processed metal sheet by causing a relative movement between the detection beam and the processed metal sheet, during the scanning, determining a position of an edge of the metal sheet hole by monitoring the detection beam, determining, from the determined hole edge position, a geometric configuration of the metal sheet hole, performing a comparison of the determined geometric configuration of the metal sheet hole with a corresponding desired hole configuration; and then sending a signal indicating information about the metal sheet processing operation, based upon the comparison.

Abstract: A punching machine is provided with a tool holder for a punching tool and a die having a cutting edge which can be passed by the punching tool in a machining stroke direction and a return stroke direction. The machine includes at least one work support, supported by at least one spring element. The work support is arranged in the region of the die, and the spring force of the spring element is adjustable.

Abstract: A method of processing a sheet metal sheet with a combined punching and forming machine includes spraying a lubricant onto on a lower side of the sheet metal sheet in a first forming position on the sheet, forming the sheet metal sheet at the first forming position with a first forming tool, and forming the sheet metal sheet with the second forming tool at a second forming position on the sheet metal sheet after spraying the lubricant onto the first forming position and before forming the sheet metal sheet at the first forming position.

Abstract: Devices are provided for detecting a mutual reference position of tool parts of a pressing tool, e.g., a punch and die. The device include (a) first and second reference elements that are moveable, by the pressing device, into a relative position that corresponds to a predetermined relative position of the first tool part and the second tool part as mounted in the mountings; (b) a control pressure generator that generates a control pressure when the first and second reference elements are moved into the relative position; (c) a switch that is activated by the control pressure; and (d) a detection unit that is activated by activation of the switch to detect the relative position of the first and second reference elements.

Abstract: A press adapted for machining a workpiece, in particular for embossing and/or punching metal plates, includes a pressing tool that includes a first tool part mounted in a first tool mounting and a second tool part mounted in a second tool mounting. The first part and the second part are located so as to be on opposing sides of the workpiece during machining of the workpiece. The press further includes a pressing drive adapted to move the first part and the second part toward and away from each other in a stroke direction during machining of the workpiece and first and second reference elements, where the reference elements are moveable into a relative position that corresponds to a predetermined relative position of the first tool part and the second tool part as mounted in the mountings.

Abstract: A mechanical bending device (8) for bending flat workpieces (6) has at least one bending tool assembly (9) which includes at least one tool part that can move by means of a bending tool drive (27). When acted on by the tool part that moves, the workpiece can be bent along a bending line (11). The movable tool part is comprised of a multiplicity of adjacent segments disposed in the direction of the bending line (11), which segments can be selectively connected to the bending tool drive (27) to provide the desired operational length for the bending tool assembly. The machine tool incorporating the mechanical bending device can also include a mechanical cutting device so that workpiece parts can be both bent and machine cut in the same machine tool.
