Description

A mechanical press is a common manufacturing machine that is used to form and cut sheet metal. Presses can use mechanical, hydraulic, or pneumatic power to delivering a force over the stroke of the machine. The benefit of mechanical presses is the high stroking rate that can be achieved with low energy input while in use. Mechanical presses use a flywheel to store energy and a series of linkages to convert rotational motion into linear motion. Some forming operations like coining and squeezing benefit from a dwell at the bottom of the stroke, a position commonly referred to as bottom dead center (BDC). This research explores models for different mechanical systems that obtain this desired dwell. The designs presented include variations of a knuckle joint press mechanism and variations of a geared five bar with connecting rod and sliding output. Each of the mechanisms is being developed as a solid model and animation to assess the viability of the proposed designs.
