Patent number: 7975522Abstract: The present invention is an assembly and method for continuously manufacturing fasteners. A die press actuated at a first speed receives the contoured wire into a die having a piercing element for piercing an aperture and a cutting element for cutting a fastener from the wire. A guide receives the fasteners from the die press and a drive unit engages the fasteners oriented by the guide and conveys the fastener to an elevated height relative to a tapping device. The guide redirects the fasteners by a first router. The fasteners are gravity fed into the first router and redirected to one of the tapping devices. Each tapping device has a tapping element for forming internal ribs in the aperture of the fastener. The tapping devices each actuates at a second speed that in aggregate is generally equal to the first speed of the die press.Type: GrantFiled: February 29, 2008Date of Patent: July 12, 2011Assignee: Whitesell International CorporationInventors: Richard P.

Patent number: 5775163Abstract: A transfer arrangement for a multistation press has two parallel gripper rails on a carrier and can be moved, together with the carrier, along a transfer curve. The gripper rails carry gripper fingers which are assigned to one another in pairs and which can be moved toward and away from one another by an oppositely directed movement of the gripper rails. The application movement is generated by parallelogram transmissions which are used for the bearing and for the drive of the gripper rails. The parallelogram transmissions are driven from a single drive source by a cardan shaft which permits the implementation of the transfer movement without any change of the relative position of the gripper fingers with respect to one another. Such a transfer arrangement is arranged on one side of the row formed by the tools and permits good access to the workpieces from the respective other side. As required, the entire transfer arrangement can be removed from the tool area, preferably in a swivel movement.Type: GrantFiled: December 4, 1996Date of Patent: July 7, 1998Assignee: Schuler Pressen GmbH & Co.Inventor: Gunter Riedisser

Patent number: 5713236Abstract: A transfer mechanism for a progressive forging machine in which the fingers for transporting workpieces from station to station are arranged to pick the workpieces axially out of dies from which they are being discharged, transfer the workpieces laterally from the discharging stations to receiving stations, place the workpieces axially into the receiving stations, and then open wide enough to clear tooling on the slide and return to the original delivery stations. Included in the mechanism is an adjustment for the axial stroke of the fingers and a cassette mounting for the fingers enabling them to be readily replaced with another cassette for a changeover in the workpieces being forged.Type: GrantFiled: February 8, 1995Date of Patent: February 3, 1998Assignee: The National Machinery Company,Inventors: Steve C.
