Publication number: 20080196471Abstract: In a method of cutting high-tensile workpieces, in particular sheet metals of martensite steel, the workpiece is subjected to a bending stress prior and during a shearing process. The bending stress causes a substantial component of a tensile force transverse to a desired cutting contour. Tensile stresses are superimposed to the shearing stresses, which favor the beginning of the workpiece separation. The bending stress is preferably selected so that the resulting tensile stress exists at a side facing the cutting tool.Type: ApplicationFiled: May 12, 2005Publication date: August 21, 2008Applicant: NANOFERENZ GmbHInventors: Stefan Fellenberg, Juergen Fahrenbach, Hans-Joerg Schaller

The clamping force is increased to 40% or more of the ram force. The force exerted by the sheet metal holding device during the penetration of the workpiece can be further increased. The increase in the clamping force preferably takes place in a controlled manner as a function of the press angle.Type: ApplicationFiled: November 6, 2006Publication date: May 10, 2007Applicant: Schuler Pressen GmbH & Co.

Patent number: 7024991Abstract: In an overload safety device in a press, having a driving device with a drive shaft, a slide carrying out an oscillating movement and a connecting rod which connects the drive shaft with the slide and has a large and a small eye, the connecting rod is provided with a pressure element disposed displaceably in the longitudinal direction of the connecting rod. The pressure element acts at least indirectly upon a fluid such that, when a certain force acts upon the connecting rod, a pressure increase occurs in the fluid. The fluid is guided to a pressure limiting valve which, when a predetermined pressure is exceeded, causes an interruption of the slide movement.Type: GrantFiled: June 26, 2003Date of Patent: April 11, 2006Assignee: Schuler Pressen GmbH & Co. KGInventor: Juergen Fahrenbach
