Hydrostatic pressing apparatus

摘要

A hydrostatic pressing apparatus comprising a container having a cavity for accommodation of a blank and communicating with a high pressure source, and a die and a plug which seal the cavity on opposite sides and which are installed in movable locks. The apparatus has a power frame formed by two slabs which are arranged on opposite sides of the container at a distance from one another which is slightly greater than the container length. The die is arranged outside the container and bears with its lock against one of the slabs, and the plug lock bears against the other slab, the cavity of the container being of different diameters along its length, the diameter being the largest on the plug side so as to obtain at the plug a force sufficient for causing the power frame to move to press the die against the container during hydrostatic pressing.
