Advancements in Quick Die Change Technology: Meeting the Demands of Modern Manufacturing

The concept of quick die change, which was introduced decades ago, has now become a cornerstone of lean manufacturing practices in the majority of stamping shops. As manufacturing processes continue to evolve, there is a growing demand for quick die change (QDC) equipment that not only enhances speed but also prioritizes safety. This has led to upgrades and expansions in QDC lines to meet the evolving requirements of the industry.

David Fischer, the engineering manager at Hilma, a division of ROEMHELD North America, emphasized the importance of adapting to variations in production volume. This necessitates even faster die changeovers and the implementation of economical die clamp and handling systems. Recent advancements in QDC technology include force evaluation systems for magnetic die clamping, automatic positioning and clamping, the development of thinner magnetic clamping plates, the introduction of trackless carts, and the integration of automated storage and retrieval systems. These innovations not only streamline operations but also contribute to improved efficiency and productivity in stamping shops.

Customized Solutions for Enhanced Safety and Efficiency in Quick Die Change

“Shorter runs and more frequent die changes mean more press downtime. So, die changes must be quicker.” He added this caveat: “But safety cannot be sacrificed for speed; they need safe clamping systems and ergonomic die exchanges.”

“We have a variety of products that can provide custom clamping and handling for most applications, with a mix of standard products,” Fischer said. “Newer components include smaller and more economical electrical and pneumatic power units, suitable for small and midsize QDC systems and presses.

“Additional die handling products include hydraulic or spring-actuated ball and roller lifters. The positions and spacing of balls and rollers in the lifter bars can be adjusted to fit the application. This can greatly reduce costs when moving lighter dies. Ergonomic hydromechanical manual clamps, with clamp force indicator pins, can provide high clamp forces and very little tightening torque.”

“We work directly with the user to customize a system for their needs,” Fischer said. “This includes types and quantities of clamps, die rollers, die supports, pumps, and valves.”
