Turret Punch Press Assembly

Traditional turret punch press tool designs utilize coil springs (die springs) to facilitate the stripping mechanism of a die. Rather than using a ram to push the punch through the sheet metal and pull it out, the spring automatically retracts the punch. This allows the ram to only have to work in one direction. The result reduces wear and extends the cycle life of the press.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process.

SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series (Figure 1), they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling
