Patent number: 5778721Abstract: Machine tools are known, for forming workpieces, such as sheet metal, with tooling made of two tool halves arranged on opposite sides of the workpiece to be formed. One half of the tooling has at least one pressure element that can move against the workpiece and act on it and the other half of the tooling has at least one counter-pressure element that works with the pressure element to form the workpiece, and it is also movable against the workpiece. The movement of the pressure element against the workpiece activates the drive of the counter-pressure element in the direction opposite to the movement of the pressure element against the workpiece.Type: GrantFiled: April 24, 1996Date of Patent: July 14, 1998Assignee: Trumpf GmbH & Co.Inventors: Hans Klingel, Werner Erlenmaier

Patent number: 5759086Abstract: A machine tool for cutting workpieces includes a cutting head with at least two cutting units each providing cutting beams directed at the workpiece so as to impinge thereon closely adjacent each other to cooperate in the cutting action. The machine tool includes a worktable to support the workpiece, and the workpiece and cutting head are relatively movable to provide a cutting line in the workpiece. At least one of the cutting units is movable relative to the other so that the angular relationship of the cutting beams may be varied, and the supply of the cutting medium is separately controlled for the cutting units. In one embodiment the cutting beams are high speed water jets which may contain abrasive and the cutting characteristics of the jets may be varied.Type: GrantFiled: December 9, 1996Date of Patent: June 2, 1998Assignee: Trumpf GmbH & Co.Inventor: Hans Klingel

Patent number: 5667707Abstract: On laser cutting machines the laser cutting head is movable relative to the laser generator, respectively relative to the workpiece to be cut, in a plane parallel to the workpiece by means of a drive controlled by a numerical control. The laser cutting head also has an adjusting device for adjusting the focal position of the laser beam, by means of which the focus can be shifted with respect to the laser cutting head perpendicular to the workpiece. The position of the laser beam focus perpendicular to the workpiece influences the cutting quality obtained, respectively the resulting cutting characteristics. A laser cutting machine which is functionally efficient under workshop conditions and suitable for automatic operation, for which a sure optical adjustment of the focal position is possible, has not been available up to now. The new laser cutting machine should eliminate this problem.Type: GrantFiled: May 2, 1995Date of Patent: September 16, 1997Assignee: Trumpf GmbH & Co.Inventors: Hans Klingel, Juergen Michael Weick

Patent number: 4869141Abstract: A punch press has a ram assembly with a lower portion which is rotatable and reciprocatable about a vertical axis and, a die holder which is rotatable about the same axis. A gear mechanism is coupled between a drive motor and the lower portion of the ram assembly and the die holder to effect simultaneous rotation thereof, which effects reorientation of the tooling relative to the X and Y axes of the punch press. In this fashion, rotation of the tooling will enable a single set of tooling to effect cutouts of different orientation in a workpiece relative to the X and Y axes, and movement of the sheet material along the X and Y axes together with such rotation of the tooling enables complex configurations to be nibbled or cutout with a limited number of sets of tools.Type: GrantFiled: October 16, 1984Date of Patent: September 26, 1989Assignee: Trumpf GmbH & Co.Inventor: Hans Klingel

Each pair of opposed high frequency electrodes has a central plane offset at an angle relative to the central plane of an adjacent pair of high frequency electrodes. The angle is approximately 360 degrees divided by the number of pairs of high frequency electrodes. The high frequency electrodes contact the rectilinear tube device over a significant lateral distance.Type: GrantFiled: July 6, 1987Date of Patent: January 3, 1989Inventor: Hans Klingel

Patent number: 4753099Abstract: A bending press includes a work support table comprised of a pair of support elements, at least one of which is mounted on the frame for movement generally vertically relative to the work support plane. Workpiece positioning elements are located on opposite sides of the work station defined by the upper and lower dies and are movable horizontally of the work support plane defined by the work support table. A drive motor effects horizontal movement of at least one of the workpiece positioning elements relative to the other positioning elements so as to move the workpiece on the work support table and effect its precise positioning in desired positions relative to the work station. The machine includes a computer control for operating the various drive motors and may include a rotatable work support table for effecting rotation of the workpiece to reorient it relative to the work station.Type: GrantFiled: September 5, 1986Date of Patent: June 28, 1988Assignee: Trumpf GmbH & Co.Inventor: Hans Klingel

Patent number: 4719691Abstract: A tool storage and transfer mechanism for a tool changer punch press includes a magazine with at least two tool carrying elements located in spaced positions about its periphery adapted to releasably seat punch tooling. The magazine is mounted for rotation about a horizontal axis which is spaced below the plane of the work support surface of the punch press with the distance being dimensioned to locate the tool carrying elements in horizontal alignment with the tool mounting receptacles of the punch press when the magazine is rotated to locate them in the uppermost position. A peripheral portion of the magazine is of reduced radial dimension so that it will not extend above the plane of the workpiece support surface of the press when rotated into the uppermost position. A transfer mechanism effects the transfer of tooling between the uppermost tool carrying element of the magazine and the tool mounting receptacle of the punch press.Type: GrantFiled: October 31, 1985Date of Patent: January 19, 1988Assignee: Trumpf GmbH & Co.Inventor: Hans Klingel

Patent number: 4675501Abstract: A laser beam apparatus for processing workpieces includes a beam transmission system providing a beam pathway therethrough from the laser beam generator to a laser focusing head, and this system has at least one mirror which reorients the direction of the beam in the pathway and which is adjustable in at least one axis relative to the pathway. At a point downstream of the mirror is a laser beam sensing means which senses deviation of the beam from its optimum path and generates a signal which is transmitted to deviation responsive means to provide an output. This output may include a visual indicator which enables the operator to effect manually the necessary adjustment of the mirror or an automatic operating means for effecting corrective movement of the mirror. The apparatus has a laser cutting head containing a beam directing mirror and the focusing lens with a deviation sensing means therebetween.Type: GrantFiled: October 22, 1984Date of Patent: June 23, 1987Assignee: Trumpf GmbH & Co.Inventor: Hans Klingel
