Patent number: 10974469Abstract: A method for manufacturing a semifinished product or part is disclosed in which a metal support embodied as a metal sheet or blank is covered with at least one prepreg containing a thermally cross-linkable thermosetting matrix with endless fibers, the thermosetting matrix of the prepreg is pre-cross-linked by means of heating, and the metal support covered with the pre-cross-linked prepreg is formed into a semifinished product or part by means of deep drawing or stretch deep drawing. In order to enable plastic deformation in fiber-reinforced regions of the metal support, it is proposed that during the pre-cross-linking of the thermosetting matrix of the prepreg, its matrix is transferred into a viscosity state that is higher than its minimum viscosity and prior to reaching its gel point, the prepreg is formed together with the metal support.Type: GrantFiled: December 12, 2016Date of Patent: April 13, 2021Assignee: voestalpine Stahl GmbHInventors: Carola Eyssell, RĂ¼diger Heinritz, Reiner Kelsch, Gerhard Mayrhofer, Christian Rouet, Johannes Riegler

Patent number: 10686273Abstract: To provide a connector that is less deformable even under a high contact pressure. A connector includes a housing having a fitting chamber, and a terminal that comes into conductive contact with a pin terminal in the fitting chamber. The terminal includes a fixing base fixed to the housing, a contact member extending from the fixing base and pressed against the pin terminal, and right and left press-supporting members extending from the fixing base. The press-supporting members include respective contact-receiving parts that face the contact member in the fitting chamber and are positioned side by side in a direction intersecting a direction of insertion of the pin terminal into the fitting chamber. Since the pressed pin terminal is received by the plurality of contact-receiving parts, the pressing force can be dispersed therebetween. Hence, the deformation of the contact member and the contact-receiving parts can be prevented.Type: GrantFiled: March 14, 2019Date of Patent: June 16, 2020Assignee: IRISO ELECTRONICS CO., LTD.Inventor: Yoshiyuki Ogura

Patent number: 5544549Abstract: A process for producing a steel punching sheet that has the same ideal dimension over the entire length of the punching edge has the following steps: producing webs carrying punching edges on a steel starting sheet; processing the punching edges, wherein the distance between the punching edges and the back of the sheet is adjusted to a positive tolerance with respect to an ideal dimension; and grinding the back of the sheet to remove material in excess of the ideal dimension to within a tolerance of not more than 0.02 mm, more particularly a tolerance of not more than 0.005 mm. Advantageously, the process includes the following additional steps: adjusting the distance between the punching edges and the back of the sheet to a negative tolerance, with respect to an ideal dimension, and applying material to the back of the sheet to make-up for the negative tolerance up to a positive tolerance of not more than 0.02 mm, more particularly, a tolerance of not more than 0.Type: GrantFiled: May 9, 1994Date of Patent: August 13, 1996Inventor: Fritz Helferich

Patent number: 4528836Abstract: A cold metal working process gradually changes the cross-section of a copper band to a wider band having one or more sections of reduced thickness. A hammering tool having a chevron-like protrusion, formed by two convergent elongate ridges with long and narrow flat crests, performs a succession of elemental hammered compressions on the band. The metal band, between blows of the hammering tool, is advanced toward the wider part of the chevron-like protrusion and enables the reduced thickness section to be progressively widened by hammering, with the long flat crests of the two ridges, on narrow strips of the portions of the band adjacent to the reduced thickness section. The material displaced from the hammered indentation at each elemental compression of the narrow strip is displaced substantially laterally and results in a widening of the band without an appreciable increase in the initial thickness of the other portions of the band's cross-section.Type: GrantFiled: July 31, 1984Date of Patent: July 16, 1985Inventor: Gerard Durand-Texte
