Patent number: 6871521Abstract: A method of operating a bending press, in particular an edging press, and a bending press for carrying out this method. For each drive of a drive arrangement, the actual pressing force is detected for the displaceable press beam during a bending process for the workpiece and a relative position of the pressing tool or tools by reference to the longitudinal extension of the press beams is determined on the basis of a force ratio. Different displacement paths of the drives and the displaceable press beam at the respective force-application point of the drive are then determined in an evaluation and/or computer unit, which is provided with a data memory for production and machine data, and corresponding control signals for the drive system are generated in the control unit and actuator elements of the drives are displaced by the displacement paths determined for each drive.Type: GrantFiled: February 12, 2003Date of Patent: March 29, 2005Assignee: Trumpf Maschinen Austria GmbH & Co. KGInventor: Gerhard Sperrer

Patent number: 6772682Abstract: A shutheight adjustment system incorporating tie rods and accompanying hydraulic tie rod nut assemblies in connecting a bed to a bolster of a mechanical press for dynamically altering the tensioning of the tie rods. Each hydraulic tie rod nut assembly includes a cylinder with an inner sliding piston threadably engaging the tie rod. A pressurizing mechanism injects pressurized fluid within a chamber formed by the piston and cylinder. By increasing pressure within the chamber of the hydraulic tie rod nut assembly, compression between the press bed and press bolster may be increased, thereby increasing the press shutheight.Type: GrantFiled: February 13, 2003Date of Patent: August 10, 2004Assignee: The Minster Machine CompanyInventors: Edward A.

Patent number: 6474227Abstract: With a method of controlling synchronous drive of a plurality of pressing machines, each of the pressing machines has a motor, a drive shaft to which a torque of a flywheel driven by the motor is transmitted through a clutch and a slide driven by the drive shaft so that a rotational position of the drive shaft of each of the pressing machines is synchronous each other. The method has a step of detecting actual velocity information of the motor and a step of detecting actual rotational-position information of the drive shaft. The detected actual rotational-position information is compared with the reference rotational-position information from a reference rotational position information generating section. Based on the result of the comparison, the reference velocity information from a reference velocity information generating section is compensated into characteristic reference velocity information of each of the pressing machines.Type: GrantFiled: January 3, 2001Date of Patent: November 5, 2002Assignee: Aida Engineering, Ltd.Inventor: Shinichi Narita
