Abstract: A machine provided with a bed on which is mounted a frame having an explosion chamber communicating with the space of a power cylinder whose plunger supports a punch, an anvil block located opposite to the punch and carrying a die arranged coaxially with the punch, and a device for returning the plunger to the initial position. The frame and the anvil block are rigidly secured on the bed, the space of the power cylinder is open at both ends and a hole providing communication between the space, the explosion chamber is located substantially in the middle of the length of the space, the plunger supporting the punch and a second similar plunger with a second punch being installed in the space opposite to the axis of the hole while a second anvil block is rigidly installed on the bed opposite the second punch symmetrically with the first anvil block relative to the same axis, the second anvil block being rigidly connected to the first anvil block and carrying a rigidly-secured second die.

Abstract: A device for briquetting loose materials with the use of impulse energy of detonation, in which there is provided a bed plate on which are mounted movably a housing and an anvil. The housing accommodates an explosion chamber and a first actuating cylinder space communicating with the chamber, with the cylinder rod carrying a plunger. Both the housing and the anvil are mounted on the bed plate with a possibility of rolling back at the moment of explosion along the axis of the first actuating cylinder towards its rod, and arranged in succession intermediate of the housing and anvil are a container having a through axial conduit for material to be briquetted, in which at the moment of explosion, the rod with the plunger are moving, and a die which is integral with the container and in which a briquette is formed under the pressure of the plunger, with the container and the die being aligned axially with the first actuating cylinder.
