Patent number: 10300515Abstract: A progressive forming machine with die and tool units, one of said units sliding a limited distance along its axis and biased by a spring force towards the other unit, the units each having an end face with a smooth surface finish adapted to press against the smooth surface finish of the end face of the other unit, the end face area of one of the units being relatively small compared to its major cross-sectional area whereby a high contact pressure between the end faces is obtained for a given spring bias force such that extrusion/cooling oil coating a workpiece received in cavity portions is restrained from leakage from the cavity portions across said end faces during a hydrostatic trapped extrusion shaping the workpiece to a degree beyond limits of conventional cold-forming processes.Type: GrantFiled: August 12, 2014Date of Patent: May 28, 2019Assignee: NATIONAL MACHINERY LLCInventors: Thomas E.

Patent number: 7784318Abstract: A method and apparatus for detecting a turned blank at a workstation in a progressive forging machine comprising simultaneously monitoring both the force on a tool in the workstation and the crank angle of the machine, determining a reference crank angle when the tool is subjected to a force at the workstation about to deliver a blow and a blank in the workstation is properly angularly aligned, operating the machine to forge blanks in a normal manner when a force on the tool at the workstation occurs substantially at the reference crank angle, and interrupting said normal manner when the force on the tool at the workstation occurs before said reference crankshaft angle to enable the blank being formed at the workstation to be separated from remaining blanks being forged in the machine.Type: GrantFiled: March 27, 2008Date of Patent: August 31, 2010Assignee: National Machinery LLCInventors: Donald E.

Patent number: 4631950Abstract: A progressive forging machine is disclosed in which a tool pack is removably mounted on the machine to facilitate tool changeovers and the like. The tool pack includes tool carriers guided in bearings on the tool pack for reciprocating movement by a bolster mounted on the machine frame. Because the tools are guided by the tool pack itself, inaccuracy of bolster alignment does not adversely affect the position of the tooling. The tool pack also provides a shear, a transfer, strippers, and kickouts for both the dies and the tools. The drives for the various components on the tool pack are provided on the main machine frame and are either automatically connected during installation of the tool pack or are easily connected at the time of such installation. Because the tooling is guided by the tool pack itself, deflections within the main machine frame created by forming loads do not adversely affect tooling alignment.Type: GrantFiled: May 17, 1984Date of Patent: December 30, 1986Assignee: The National Machinery CompanyInventors: Thomas E.
