FORGING MACHINE PROVIDED WITH AUTOMATIC TOOL EXCHANGER

摘要

A fully automated tool changer system for multi-station forging machines is disclosed. This system provides a tool and die supporting head providing spaced support rails on which the tools or dies are supported during the transfer between the machine and the tooling rack. Such head is operable to properly position tools and dies which have different diameters for insertion into the cylindrical cavities in which they are mounted within the machine. A second tooling head is rotated to an operative position when the elements of the shear are to be changed. The tool heads are directly supported on the machine frame or the tool rack so that the loads of installing and removing the tooling are directly transmitted to stationery supports and need not be absorbed by the power transfer system. Further, the supports are arranged so that a high degree of positional accuracy is provided during the tool changing operations. Powered clamping means are provided to releasably lock the tooling in its installed position and is structured to assure that adequate locking is provided without jamming. A flushing system is provided to insure that debris does not cause difficulty during the tool changing operations.
