Definitions

  • the invention relates to a processing unit of a machine tool for punching machining of workpieces, in particular sheets, with a punching tool carrier, to which a punching tool is attachable, and with a punch drive, which has a transverse drive element, wherein the punching tool carrier along a lifting axis is movable by the transverse drive element is driven by a punch drive motor of the punching drive relative to the punching tool carrier with a transverse drive movement along a transverse movement axis which extends in the transverse direction of the stroke axis of the punching tool carrier.
  • the invention further relates to a machine tool for punching machining workpieces with a processing unit of the above type.
  • the drive-side wedge gear elements cooperate with output-side wedge gear elements, to which the press tool is connected and which move together with the press tool along the lifting axis due to the movements carried out by the drive side wedge gear elements in the transverse direction of the lifting axis.
  • the machining unit In addition to a punching unit with a punching tool carrier for a punching tool and with a punching drive for moving the punching tool carrier and the punching tool along a lifting axis, the machining unit according to the invention has a scraper unit with a scraper for the punching tool of the punching unit, wherein the scraper carrier and thus also the scraper decoupled from the punching tool can be positioned along the stroke axis.
  • the punch drive comprises a transverse drive element, which is driven to generate movements of the punching tool carrier along the lifting axis with transverse drive movements along a transverse axis of movement of the lifting axis extending transverse movement axis.
  • the transverse drive element of the punching drive is movable in its transverse drive movements relative to the scraper carrier along the transverse movement axis.
  • the punch tool carrier and the scraper carrier can move relative to each other along the lifting axis.
  • the position of the scraper carrier and thus the position of the The scraper to be attached to the scraper carrier along the lifting axis can consequently be defined independently of the position which the punching tool carrier and the punching tool take along the lifting axis. Movements of the transverse drive element of the punch drive along the transverse movement axis do not affect the position of the scraper carrier and the scraper along the lifting axis.

Rather, positions which the scraper occupies along the lifting axis, both defined in a along the stroke axis to the workpiece to be machined working stroke of the punching tool as well as executed in the opposite direction return stroke by the punching tool or by the punch tool provided with the punching tool. Movably coupled with the punching tool, the scraper moves during the working stroke of the punching tool along the lifting axis in the direction of the workpiece to be machined until the scraper touches on the workpiece.
  • the punch When supported on the workpiece and thus inevitably in the direction of the lifting axis ortsunver basiclichem scraper, the punch continues its working stroke along the stroke axis until the workpiece is machined punching. Upon reaching the dead center of the power stroke of the working stroke opposite return stroke of the punching tool is initiated and the punch moves first relative to the still sitting on the workpiece scraper in the opposite direction of the working stroke along the stroke axis until the punching tool emerges from the now punched machined workpiece. Once the punching tool has exited the workpiece, it will carry the wiper in the return stroke direction with a movement away from the workpiece.
  • the wiper In the "passive wiper” mode of operation, the wiper is moved along the lift axis to a position in which the wiper is spaced from the workpiece. When spaced from the workpiece scraper, the workpiece is machined by means of the punching tool, which performs relative to the scraper a correspondingly sized stroke along the lifting axis.
