Abstract

24,908. Briede, 0. Nov. 19. Forging.-In a machine for making bolts and rivets, a blank is upset while held iu divided dies, the parts of which are securely clamped prior to the insertion of the blank and during the heading and are then released to facilitate ejection. The blanks are inserted in the die and are headed by the same forward movement of the heading-tool and are ejected as this moves back. The holding-dies 11 consist of two more parts which are clamped together by spring-pressed wedge surfaces 13, 14, Fig. 3, the pressure being released after heading by a cam 18 operated by a rod 8. The back-stop 7, Fig. 1, which serves also as an ejector is mounted on a plunger 6, the back support 32 of which is adjustable in a screwed sleeve 26. Cooling and cleaning liquid is admitted by a passage at the side, and when the plunger is operated by the slide 21 and the lever 28, the liquid is forced through the die.
