ABSTRACT:
In a tube-upsetting press, of the kind having a vertically split die with vertically spaced shaping faces for successive setting operations, metal tubes to be upset are handled by sets of grippers which move cyclically along a closed path perpendicular to the axes of the tubes and the die and respective grippers move cyclically towards and away from the die, these movements being so synchronized that successive tubes are gripped, moved into line with one shaping face of the die and advanced thereinto by a first gripper of the set, shifted to the next shaping face by another gripper of the set, and withdrawn from the die by a further gripper of the set after upsetting. Fixed retaining grippers hold the tubes during upsetting, and oscillating transfer grippers move the tubes laterally from a supply table into alignment with the first die-feeding grippers of the set. The drive train for the several sets of grippers is described.
