Abstract
A press for attaching nuts to pipes has a lower holder (6) fitting in and holding a pipe (60). A basal portion of this holder supported on the rear part of a lower base (2) moves up and down, and its forward portion extends to the front part of a lower base. Lifters (30) bear against and support the forward portion so as to keep it lifted a slight distance. Stoppers (31) bear against and support an intermediate region of the holder to be lifted a slight distance, and also bear against an end of the pipe (60) and retaining it at a prescribed position. A nut feed passage (10) extends in an outer surface of the lower holder from its basal to forward portion, and a nut pusher (14) is disposed in the forward portion. A cam rod (21) inserted in the lower holder (6) has a frontal oblique cam surface (22) for driving the pusher (14) to a nut releasing position (12), and a cam actuating means (25) is for the rod. An upper holder (3) moves in a direction perpendicular to the lower holder (6), a caulking die (47) is carried by the upper holder (3), and a die driving means (50) is for the caulking die, such that the press is rendered easy to automate.
