Abstract: A method for manufacturing a pressing tool includes shaping a blank, which is able to be hardened, at least in part, to a final size of a pressing jaw. Then, a laser beam is applied to at least one selected region of a surface of the pressing jaw so as to form at least one hardened surface layer.
Abstract translation: 一种用于制造压制工具的方法包括将能够至少部分地硬化的坯件成形为压制钳口的最终尺寸。 然后，将激光束施加到按压钳口的表面的至少一个选定区域，以便形成至少一个硬化表面层。

Abstract: A separating device for the chipless cutting to length of plastic workpieces, in particular plastic pipes, has a support part as support for the plastic workpiece and a blade which is movable relative to the support part. The separating device is configured to supply a wetting liquid to the blade at its contact point with the plastic workpiece to be machined. A method for the chipless cutting to length of a plastic workpiece uses a water-containing gel as an application lubricant for the contact points on the workpiece side during the chipless cutting to length of a plastic or plastic composite workpiece.

Abstract: A press die for a pressing tool for pressing round tubular sections of at least two workpieces has a through-hole with a circumferential die surface. It includes at least two die parts. Each of the at least two die parts comprises a circumferential section of the through-hole. At least one of the die parts comprises a round target contour over at least one region of the associated circumferential section of the through-hole. At least one other die part comprises a contour deviating from the round target contour over at least one region of the associated circumferential section of the through-hole. Thus, the circumferential sections of the through-hole associated with the at least two die parts are asymmetrical relative to each other with respect to a chord formed by the associated circumferential section of the through-hole.

Abstract: An apparatus for cutting corrugated pipes to length includes a clamping device configured to act radially with respect to an axis so as to fix a corrugated pipe in a machining position. The apparatus also includes a cutting tool moveable into an active position against the corrugated pipe in the machining position and configured to bring about a separation by moving the cutting tool and corrugated pipe relative to one another. A stop device is configured to engage in a corrugation trough of the corrugated pipe wherein a spacing between the cutting tool and stop device is variable in the axial direction with respect to the axis.
