Patent number: 6408671Abstract: A press has a tool which comprises an upper tool part and a lower tool part. The upper tool part is held on the press slide, while the lower tool part is stationarily mounted in the press frame. A movable forming element, such as a shearing blade, is provided in the lower tool part. The press drive is used for driving the shearing blade. For this purpose, a hydraulic force transmitting device is provided in the lower tool part and is actuated by way of a pressure pin. For the actuation, the slide or an element fixedly connected with the slide is used, the slide, in turn, being driven by the press drive. A hydraulic force transmitting device in the lower tool part permits a liberal tool construction and an arrangement of corresponding force transmitting devices for the at least temporary coupling between the slide and the hydraulic force transmitting device at points which hinder neither the access to the tool nor the workpiece transfer.Type: GrantFiled: October 6, 2000Date of Patent: June 25, 2002Assignee: Schuler Pressen GmbH & Co.

Patent number: 6185979Abstract: A transfer system is provided for press facilities with several successive press stations. The transfer system has divided cross traverses which, with respect to the transport direction, can be moved from the front and the rear into the tool. Each tool includes two respectively transversely divided traverses. For receiving and depositing the workpieces, the cross traverses are adjusted toward and away from one another. In addition, when the tool is closed, the cross traverse are laterally moved past the tool. As required, they may be changed for this purpose into an overtaking position, which can be carried out, for example, by a swivel drive. The transfer system permits a shortening of the minimum time for which the tools must be open with respect to the transfer system and thus allows an increase of the stroke number of the press.Type: GrantFiled: May 5, 1999Date of Patent: February 13, 2001Assignee: Schuler Pressen GmbH & Co. KGInventor: Dietmar Schöllhammer

Patent number: 6176365Abstract: A control device for electric direct drives of a transfer system contains at least one monitoring device which, in the case of the malfunctioning of a direct drive, switches the control device into an emergency operating mode. In the emergency operating mode, the control device disconnects the linear drive affected by the malfunction from power and controls the remaining direct drives preferably at full power or at a slightly higher power. Thereby, a freedom from collision is established between the forming tool and the transfer device, after which the press is preferably stopped.Type: GrantFiled: December 18, 1997Date of Patent: January 23, 2001Assignee: Schuler Pressen GmbH & Co.Inventor: Peter Klemm
