Progressive dies perform fundamental cutting and forming operations simultaneously at various stations within a die during each press stroke.
This program, part of the Fundamentals of Tool Design Video Series, explores the essential design variables used in part/strip development that contribute to part quality, progressive die tool maintenance, tool life, and tool cost.
The Progressive Die Design Essentials segment details part orientation, part lift, the use of cams, part transport, stretch webs, ribbon strips, stock positioning using direct and indirect pilots, first station operations, piercing distribution, die punches, forming operations, idle stations, part and scrap ejection, die clearances, and more.
The Lubrication Factors in Progressive Die Design segment examines the types and effective use of lubricants in progressive dies to control friction, extend tool life and improve part surface quality.
