  • Patent number: 4631950
    Abstract: 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.
