  • Patent number: 4586364
    Abstract: A transfer system for forging machines or the like is disclosed in which a transfer assembly is cantilever-mounted on a powered support for easy removal and replacement, e.g., to provide access to the forging machine dies. Mounting means including mating surfaces on the support and the transfer assembly, which, when engaged, position the transfer assembly with respect to the support. Such surfaces are contained in at least three mutually perpendicular planes. A wedge operated by a piston and cylinder actuator operates in one position to lock the transfer assembly on the support and, when retracted, permits removal of the transfer assembly by vertical movement. The mounting means is arranged to provide locating surfaces and cam surfaces which assist the operator in guiding the transfer assembly to its mounted position.

  • Patent number: 4170123
    Abstract: A multiple blow, two die metal forming machine having a drive system which is capable, without alteration, of conversion in operational mode between two blows at the first die, one blow at the second die and one blow at the first die, two blows at the second die. The various workpiece transferring elements and ejecting members are activated by the drive system in respective fixed cycles which are compatible with operation in both operational modes. Operations at the second die station are out of phase with those of the first die station by one stroke thereby allowing the transfer of workpieces between the first and second dies to occur over a relatively long period for a reduction of transfer speed and an increase in transfer reliability.
