ABSTRACT:
A slide-driving device for knuckle presses employs a side link affixed at a base end to the knuckle press, and pivoted at its outer end to a junction between links that drive the slide. The side link maintains a very small slope angle for the lower link, which raises and lowers the slide. The small slope angle prevents thrust force from being generated on the slide, and enables performing high-precision molding of products even with extrusion operations, where the molding is started from a position high above the bottom dead center of the slide. In one embodiment of the invention, the base end of the side link is rigidly affixed to the frame of the knuckle press. In a second embodiment of the invention, a bottom dead center compensation device adjusts the position of the outer end of the side link at bottom dead center to compensate for changes in the linkage.
