Applying parallelism technology in hydraulic presses--Active leveling control offsets press, tooling problems

摘要

Stamping shops are driven to offset today's increasing competition and decreasing margins by consolidating operations and processes, minimizing operator error, and reducing material scrap. To achieve this and thrive, they often must access advanced technology. One development that equips hydraulic presses to meet these challenging demands is active leveling control (ALC) (see lead image). This technology counteracts the negative effects of off-center loading; significant breakthrough shock common with high-strength steels (HSS); as well as reverse shock loading associated with nitrogen springs in dies.
