Patent number: 10328478Abstract: This disclosure relates to methods and apparatuses for punching workpieces. A punching tool is configured to move during a punching stroke along a stroke axis towards a workpiece to be punched. The punching tool is configured to move away from the punched workpiece during a return stroke. The punching tool includes first and second components configured to be coupled hydraulically for concurrent movement along the stroke axis. The punching tool includes a punching drive for moving the first component along the stroke axis. The punching apparatus is configured to move the second component relative to the first component at a first transmission ratio during the punching stroke. The punching apparatus is configured to move the second component relative to the first component at a second transmission ratio in response to a reaction force of the workpiece exceeding a threshold value of the punching drive during the punching stroke.Type: GrantFiled: January 27, 2017Date of Patent: June 25, 2019Assignee: TRUMPF Werkzeugmaschinen GmbH + Co. KGInventors: Werner Erlenmaier, Frank Schmauder

Patent number: 8574140Abstract: A mechanical device is used to change a laser nozzle of a nozzle mount of a laser processing machine. The mechanical device includes a nozzle magazine with at least one nozzle holder for storing a laser nozzle at a nozzle storage location, and a dirt collector. The nozzle holder is movable by means of a positioning device provided for that purpose or alternatively the dirt collector is movable by means of a positioning device provided for that purpose into a stand-by position defined on the mechanical device. The nozzle holder and the dirt collector can also be transferred to a position remote from the stand-by position with the respective positioning device.Type: GrantFiled: January 8, 2009Date of Patent: November 5, 2013Assignee: TRUMPF Maschinen AGInventors: Werner Erlenmaier, Frank Schmauder, Armin Felber, Reto Gedeon

Patent number: 8439811Abstract: A mechanical device is used for mounting and/or dismounting a laser nozzle on and/or from a nozzle mount of a laser processing machine for processing workpieces, especially metal sheets. The mechanical device includes a nozzle magazine having a nozzle holder support on which a nozzle holder for a laser nozzle is supported. In addition, the mechanical device has a support positioning drive by means of which the nozzle holder support is positionable together with the nozzle holder in a support positioning direction. A lifting device of the mechanical device serves to position the nozzle holder, when positioned in the support positioning direction in a lifting stand-by position, relative to the nozzle holder support in a positioning lifting direction extending perpendicular to the support positioning direction.Type: GrantFiled: January 9, 2009Date of Patent: May 14, 2013Assignee: TRUMPF Maschinen AGInventors: Werner Erlenmaier, Frank Schmauder, Armin Felber, Reto Gedeon

Patent number: 8360944Abstract: A mechanical device is used to change a laser nozzle on a nozzle receiving member of a laser processing machine for processing workpieces. The mechanical device has a nozzle magazine having a nozzle holder carrier, and at least one nozzle holder for a laser nozzle being provided on the nozzle holder carrier. The mechanical device also includes a positioning drive and a change drive, both drives having a common drive motor. Between the drive motor on the one hand and the nozzle holder carrier and the nozzle holder on the other hand, there is provided a coupling that can be switched by means of a switching device between a supply state, in which a drive connection exists between the drive motor and the nozzle holder carrier, and a change state, in which a drive connection exists between the drive motor and the nozzle holder.Type: GrantFiled: January 8, 2009Date of Patent: January 29, 2013Assignee: TRUMPF Maschinen AGInventors: Werner Erlenmaier, Frank Schmauder, Armin Felber, Reto Gedeon
