    Description

    A mechanical press is a machine that shapes parts by driving a ram into metal and deforming the material into a desirable shape. As this is an incredibly common process for forming metal parts, from pop cans to car fenders, presses see significant use in industry. This research project seeks to develop a numerical algebraic method for determining mechanical press dimensions from a desired dwell displacement pattern. This dwell pattern occurs when the ram lingers near the bottom of the stroke while the rest of the press stays in motion. Longer dwell produces improved part forming at no additional cost. This study focuses on knuckle presses architectures to test the proposed method on a variety of systems and to produce the most feasible design. Numerical algebraic methods are particularly relevant here due to their capacity to accurately describe mechanical press architectures while allowing solutions via current numerical methods that guarantee the determination of all solutions to a set of algebraic equations. As such, there are a significant number of companies designing and building mechanical presses to meet a variety of end used needs. A particularly common need is dwell, the capacity of the press to hold the position on one of its parts while the rest of the machine stays in motion. Dimensioning a new architecture for a mechanical press that produces significantly improved dwell allows for manufacturing parts at a higher rate with lower operating costs.
