Patent number: 9457498Abstract: A powder press has a die plate that supports at least one die, at least one upper press tool at an upper tool carrier, at least one lower press tool at a lower tool carrier, at least one upper linear drive acting on the upper tool carrier, at least one lower linear drive acting on the lower tool carrier or on the die plate, possibly a further linear drive acting on a transverse tool carrier, and a force measuring apparatus. The force measuring apparatus measures forces acting on the upper, lower and/or transverse tool carrier. Each linear drive may be at least two linear drives engaging eccentrically at the upper or lower tool carrier, respectively. The parallel spaced linear drives act together on a force transferring element, and the force transferring element acts on a tool carrier via spaced piezoelectric sensors.Type: GrantFiled: May 20, 2015Date of Patent: October 4, 2016Assignee: Fette Compacting GmbHInventors: Andreas Groth, Andreas Teetzen, Holger Behns
