Vertical and rotating combined pressure type multi-anvil press

Abstract

The invention discloses a vertical and rotating combined pressure type multi-anvil press, and belongs to the field of high-pressure physics. Anvil faces of an ejector anvil device of the press are arranged oppositely and coaxially; a lateral support device is arranged in the middle of the ejector anvil device; a pressure device is arranged coaxially at the rear end of the ejector anvil device, and used for applying vertical, rotating or simultaneous pressure on the ejector anvil device; the ejector anvil device consists of anvil heads, pretightening steel rings and cushion blocks; the lateral support device is in an integral or split structure, and is positioned in the center of an axis of the ejector anvil device and fixed on a rack; a cooling device consists of a water through ring and a water tank, and is used for heat dissipation of the press; and a control system is used for controlling a movement track of the ejector anvil device of the multi-anvil press to achieve that a sample in a pressure transmission medium block obtains high pressure. The multi-anvil press can achieve that the sample in the pressure transmission medium block obtains very high atmospheric pressure, so that the problem that the existing high-pressure device does not have a rotating pressure function is solved, and a material is synthesized under the action of a high shear force.
