Disc springs provide solution

Published:  26 February, 2014

SPIROL disc springs can provide a solution for design engineers in their on-going challenge to increase the productivity of turret punch presses. Traditional turret punch press tool designs have included coil springs to facilitate the pushing of the punch through the sheet metal and to pull it out.

However, in a traditional press, the material type and material thickness to be punched has been limited by the coil spring's inability to produce a high force in a short linear distance. To overcome this problem, Spirol disc springs can be stacked in series to provide a greater, more consistent stripping force than coil springs and require less space. They are reported to be becoming an instrumental component in the advancement of turret punch press tooling.
