Publication number: 20100239826Abstract: A method of manufacturing an elongated core which is buried in an elongated trim. The method includes, forming slits to a metal plate, which extend in a second direction, at predetermined intervals in a first direction so as to form core pieces between the adjacent slits; and rolling a portion of the metal plate in which the slits are not formed in the second direction to form a rolled portion extending in the first direction, and expanding the slits in the first direction to form spaces, thereby preparing a primary core in which the core pieces and the spaces are alternately provided in the first direction. Additionally, the method includes, supplying the primary core to between a pair of deformed portion forming rollers engaged with each other such that reinforcing defaulted portions extending in the second direction are repetitively formed in the first direction.Type: ApplicationFiled: March 16, 2010Publication date: September 23, 2010Applicant: TOKAI KOGYO CO., LTD.Inventor: Keiji HIROE

Publication number: 20100223974Abstract: A method of forming a clevis link having a substantially common wall thickness in a die begins with feeding a metallic strip having a uniform thickness of a predetermined value to the die. The metallic strip is trimmed to form a blank having volume necessary for forming the clevis link to the dimensional configuration required to support the motor vehicle, while maintaining substantially constant wall thickness. The clevis link has center of gravity to provide a necessary moment of inertia thereby enabling the clevis link to support the mass of the motor vehicle.Type: ApplicationFiled: May 6, 2010Publication date: September 9, 2010Applicant: RADAR INDUSTRIES, INC.Inventors: Robert D.

Publication number: 20100219030Abstract: A brake pad for a partially-lined disk brake and a method for making such a brake pad. The brake pad has a back plate, a friction lining arranged fixedly on a front side of the back plate and a damping plate provided on a rear side. At least one hook-shaped guide end adjoins a body region of the back plate in a circumferential direction. The guide end has an elevation with a material thickness D increased in relation to a material thickness d of the body region. At least one abutment face for tangential abutment in a circumferential direction is provided on the guide end and a support face is provided thereon for radial support in a radial direction. The damping plate has at least one bent-over bracket which rests against the radial support face in a bracket region of the back plate. The damping plate is offset axially to the rear relative to the bracket region in the body region of the back plate.Type: ApplicationFiled: April 29, 2008Publication date: September 2, 2010Applicant: Continental Teves AG & Co., oHGInventors: Anja Klimt, Matthias Würz, Christian Piehler

Patent number: 7770276Abstract: A device and a method are provided to allow a user to ream a hole to an accurate final diameter as desired, and at the same time, to cold work the hole to induce a beneficial residual stress that will enhance the life of the component by retarding the onset and growth of fatigue cracks in the hole. The basic design of the device has an elongated body having a forward end portion to extend through a hole to be reamed and cold worked, a reamer section formed on the circumference of the forward end portion to enlarge the hole, and a burnishing section formed on the circumference of the elongated body adjacent to the reamer. The burnishing section is operative to upset the material around the hole, so as to result in a residual stress beneficial to the hole. The reamer section is in the form of a plurality of cutting edges extending from a tip of the elongated body, while the burnishing section is also in the form of a plurality of cutting edges adjacent to the reamer section along the elongate body.Type: GrantFiled: August 25, 2006Date of Patent: August 10, 2010Assignee: Northrop Grumman CorporationInventors: Robert J. Christ, Jr., Jerrell A. Nardiello, John M. Papazian, John Steven Madsen

Publication number: 20100186474Abstract: In a method of making through-passages in a perforated U-shaped sheet metal part, an inner core is positioned between confronting legs of the sheet metal part in an area of holes, and a support bar is inserted through one hole into the sheet metal part for support of a backside of the inner core. A shaping punch is inserted through another opposite hole into the inner core, thereby forming an inwardly directed collar. After retracting the support bar and the shaping punch and transferring the sheet metal part to replace the first inner core with a second inner core, a centering bar is inserted through the collared hole into the sheet metal part to center the sheet metal part in relation to the centering bar and to support a backside of the other inner core. A further shaping punch is then inserted into the second inner core through the first hole, thereby forming an inwardly directed collar so that the two collars are aligned and form through-passages.Type: ApplicationFiled: January 26, 2010Publication date: July 29, 2010Applicant: Benteler Automobiltechnik GmbHInventors: DIETER FRIESEN, Horst Hinzpeter
