Hydraulic press for metal powder compression

摘要

The hydraulic press comprises a die bolster (10), and an upper stamp (16) and a lower stamp (14) which interact with a die bore and are operated by a hydraulic pressing cylinder. A limited dead path is provided in the power path between the pressing cylinder and the upper stamp. A pressure generator is arranged parallel to the power path and by which a pressing force is applied on the upper stamp. Preferred Features: The pressure generator acts on the upper stamp via a force measuring device. The pressure generator is a pneumatic cylinder.
