Abstract
A workpiece supporting device for a multiple-die horizontal forging press comprises a transfer pliers arranged at each recess of a die and having a movable stem operating as a workpiece ejecting means, the stem being coupled, at one end portion thereof, facing a driving mechanism, through a coupling bracket, to a driving rod, one end of which, arranged at a recess of the die respectively of the transfer pliers, houses a workpiece restraining device, formed by a rocker mechanism, which can swing about a cross pivot pin and against a spring means affecting an arm of the rocker mechanism.
Claims5
A device for supporting a workpiece to be forged in, and transferred between, successive forging dies of a cold forging pressing machine, the device comprising:
- an elongated ejecting rod extending along a first longitudinal axis into each die, and movable along the first longitudinal axis into abutting engagement with the workpiece in each die to eject the workpiece from each die,
- an elongated support rod extending through each die along a second longitudinal axis that is parallel to the first longitudinal axis, and movable along the second longitudinal axis through each die;
- a reciprocating drive mechanism coupled to both the ejecting rod and the support rod for jointly moving the ejecting rod and the support rod along their respective axes;
- and
- a workpiece restraining mechanism mounted for joint movement on the support rod remotely from each die, the restraining mechanism having an upright arm for resiliently abutting against the workpiece after ejection from each die, the upright arm and the abutting ejecting rod being together operative for holding the workpiece after ejection from each die.
