Abstract
For releasably latching the punch-carrier plate in a press for moulding screws, rivets and like articles from wire blanks, a latching member is provided which has a front hollow space which is adapted alternately to engage either of two projecting extensions integral with the punch plate, said latching member being biassed by springs which normally urge the front hollow space thereof in engagement with either extension, a follower mechanism being additionally provided to shift the latching member against the bias of the springs to permit that the punch plate may be swung towards either of its two working positions.
Claims4
A latching device for the punch-carrier plate of a press for moulding screws, rivets and like articles, in which the punch-carrier plate is mounted frontally of a ram having a rectilinear reciprocal motion in a direction parallel to the axis(es) of the press die(s) and is capable of being rotated in either sense through a preselected angle between two working positions wherein it can be latched by means mounted on the ram, characterized in that it comprises a latching member slidably mounted on the ram and equipped with a frontal hollow space adapted to cooperate alternately with either of two projecting extensions integral with the punch-carrier plate, said latching member being subjected to the action of resilient means capable of keeping its frontal hollow space in engagement with either of said extensions, means being additionally provided for controllably shifting said latching member against the bias of said resilient means out of engagement with said extensions to permit the oscillation of said punch-carrier plate from either of its working positions to the other and vice versa.
