  • Publication number: 20190168349
    Abstract: A workpiece processing machine includes a separation device for dividing an operating space into a processing region and at least one additional operating region, a laser processing head configured to process the workpiece, and a rotary workpiece changer having a rotatable workpiece support for transporting the workpiece between the processing region and the at least one additional operating region by an opening. The rotatable workpiece support has a protection wall configured to shield the at least one additional operating region with respect to the processing region. The separation device has a protection element movable between a processing position and a transport position and configured to be in abutment with the protection wall in the processing position to close the opening and spaced apart from the protection wall in the transport position. A spacing between the processing position and the transport position is adjustable based on a dimension of the workpiece.

  • Patent number: 7239780
    Abstract: A device couples a laser beam into a laser light cable having a cable connection for the laser light cable. The device includes a safety element that is operable to move to a safety position only when the laser light cable is properly connected to the cable connection. The coupling device includes an optical arrangement that is controlled by the safety element, and is disposed in the beam path of the laser beam upstream of the cable connection and only directs the laser beam towards the cable connection when the safety element is in the safety position.

  • Patent number: 7104105
    Abstract: A method, machine system and thread cutting device for producing a threaded projection on a plate-shaped workpiece and in particular on a sheet-metal workpiece. A workpiece lug (2) is cut with a threaded contour in the principal plane of the workpiece and at least a section of the workpiece lug (2) featuring at least one threaded contour (5, 6) is permanently bent in the form of a threaded projection extending at the desired angle relative to the principal plane of the workpiece. A machine system (9) for implementing the method encompasses a cutting device for the relief cutting of workpiece lugs (2) as well as a thread cutting device. Also included is a bending device (15) by means of which at least a section of the workpiece lug (2) provided with at least one threaded contour (5, 6) can be permanently bent relative to the principal plane of the workpiece. A thread cutting device of the machine system (9) is appropriately configured for that purpose.

  • Patent number: 4940880
    Abstract: A combination punch press and laser cutting machine has a C-shaped frame with a platform extending rearwardly from the web of the frame. Supported on the platform is a laser beam generator with vibration isolating fluid mounting elements disposed therebetween to support the generator on a fluid medium during operation as a punching machine. A laser beam transport system extends forwardly along the side of the frame and has a beam redirection component to effect angular and planar reorientation of the beam at the front of the frame. A cutting head is mounted on the front of the head of the frame and has a nozzle and internal optics to focus the beam through the nozzle onto the workpiece, and the cutting head is movable from an operative position in which the nozzle is located on the axis of reciprocation of the punch ram to an inoperative position in which it is spaced therefrom.
