Machine tools and methods for processing workpieces with a punching device and laser processing device
First Claim
1. A machine tool for processing workpieces comprising:
- (a) a punching device configured to hold a punching tool,wherein the punching tool comprises as punching tool components one or both of(i) a stripper of the punching tool, and(ii) a punching processing unit configured to cut a workpiece;
wherein the punching device comprises a punch-side positioning device configured to position the punching tool component of the punching tool at a definable position along an operating stroke axis of the punching device; and
wherein the punch-side positioning device comprises one or both of(i) a piston/cylinder unit configured to position the stripper, and(ii) a punch drive configured to position and move the punching processing unit along the operating stroke axis with an operating stroke directed towards the workpiece for processing a workpiece and with a return stroke counter to the operating stroke; and
(b) a laser processing device comprising;
(i) laser processing unit comprising a laser cutting head configured to direct a laser beam to a workpiece,(ii) a laser accessory unit comprising one or both ofa shielding unit configured to shield a processing site of the laser beam on a workpiece, anda workpiece holding-down member configured to hold down the workpiece during processing of the workpiece, and(iii) a laser accessory unit positioning device comprising a piston/cylinder unit configured to position the laser accessory unit with an activation movement to an operating position, wherein the operating position of the laser accessory unit is defined by the punch-side positioning device.

Abstract
A machine tool for processing workpieces, in particular metal sheets, has a punching device and a laser processing device. The punching device comprises a punch-side positioning device by means of which a punching tool component of a punching tool can be positioned in a definable position along an operating stroke axis of the punching device. The laser processing device has a laser processing unit and a laser accessory unit. The laser accessory unit can be positioned by means of an accessory unit positioning device with an activation movement in an operating position which can be defined by means of the punch-side positioning device. In the context of a method for processing workpieces, in particular metal sheets, which method is carried out using the above machine tool, the operating position of the laser accessory unit is defined by means of the punch-side positioning device.
