Estimating the term…
A slide opening system for a tool system for compacting powdery materials having an upper ram, a lower ram and an insertable tool frame in which punch holders are moved relative to the base-plate from their filling position downward to the pressing position and from the pressing position upward to the ejection position which corresponds to the filling position (ejection method), and a further punch holder is moved from the filling position downward to the pressing position and from the pressing position downward to the withdrawal position (withdrawal method), with plungers acting on slides for releasing the withdrawal plate for the withdrawal motion, whereby the plungers of the slide opening system each act on a preferably stepped slide via a pivoted lever in the form of a cam disk with leverage that changes during the opening process and at least one roll located on the lever.
A slide opening system for a press for compacting powdery materials, the press having an upper ram, a lower ram, a base plate, an insertable tool frame, a die holding plate and at least one punch holding withdrawal plate which, like the die holding plate, is moved from a filling position downward to a pressing position and from the pressing position downward to a withdrawal position, the press further having plungers acting on slides for activating the slide opening system to release the withdrawal plate for the withdrawal motion;
In a press for compacting powdery materials, the press including a base plate having a slope portion and a step portion, a die holder and a withdrawal plate movable with respect to the base plate, and plungers for activating a slide opening system, the improvement comprising a slide opening system including a stepped slide and a lever, the lever pivotally attached to the withdrawal plate such that the plungers urge the lever to pivot and engage the slide, translating the slide radially outward.
A slide opening system for a press having plungers for activating the slide opening system, the slide opening system comprising a lever pivotally connected to the press and a stepped slide, the lever being urged by the plungers to pivot, thereby translating the slide radially outward.
