Device for prestressing of a machine frame, machine frame, as well as press - and a drawing device

摘要

In order to improve the biasing of a machine frame, in which very high operating forces are introduced, the invention proposes a device for prestressing of a machine frame with a tie rod comprising a first and a further anchor head for placing on the machine frame and comprising a tension element for receiving of tensile forces between the anchor heads, whereby the tension element extends along a tensioning distance of the tie rod and wherein the biasing device characterized by the fact that at least one of the two anchor heads, and preferably both of the anchor heads, a device for reversing the direction for the tension element comprises.
