Abstract

Improvements in presses for working metal parts, characterized by comprising a frame, a pair of crankshafts mounted therein for rotation in practically parallel axes; drive means operable to rotate the crankshafts in time relation; a pair of claws for holding the lock in the frame, one of which moves in a path of movement that approaches and moves away from the support position of the work, with respect to the other; a first crank arm on a crankshaft, movable in a direction perpendicular to the path of movement of the first claw; means forming a wedge interconnection between the first crank arm and the first claw, operative because of the reciprocating movement -induced by the crankshaft- of the first crank arm, to move the first claw in the mentioned movement path; a second crank arm, on the other crankshaft; a tool holder, connected to the second crank arm, and of reciprocating movement in a direction perpendicular to the path of movement towards and from the position in which the claws are prepared to hold a work piece, in order to perform this way work in it; said wedge interconnection comprises operative means for holding said claws in the support relationship of the workpiece during a period in which the tool holder moves through a distance in which the work is performed on the workpiece .
