Abstract:
1. A very-high pressure generator comprising: a lower pyramidal block which has a base portion and a pyramidal portion formed on the base portion, the pyramidal portion being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle; a lower guide block which has a pyramidal recess in its bottom surface defined by four uniform slopes sloping up toward the center of the block, the recess being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, and an upside-down pyramidal recess in its top surface defined by four uniform slopes sloping down toward the center of the block, the recess being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, and is symmetric with respect to its horizontal center plane; a lower base block which has a lower upside-down pyramidal portion and an upper pyramidal portion, each of the pyramidal portions being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, is symmetric with respect to the horizontal center plane between the lower and upper pyramidal portions, and is provided on the top of the upper pyramidal portion with a lower anvil; four slide blocks each of which has an inner pyramidal portion laid laterally inward and an outer pyramidal portion laid laterally outward, each of the inner and outer pyramidal portions being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, is symmetric with respect to the vertical center plane between the inner and outer pyramidal portions, and is provided on the pyramidal top of the inner pyramidal portion with a side anvil; an upper base block which has a lower upside-down pyramidal portion and an upper pyramidal portion, each of the pyramidal portions being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, is symmetric with respect to its horizontal center plane, and is provided on the pyramidal top of the lower upside-down pyramidal portion with an upper anvil; an upper guide block which has a pyramidal recess in its bottom surface defined by four uniform slopes sloping up toward the center of the block, the recess being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, and an upside-down pyramidal recess in its top surface defined by four uniform slopes sloping down toward the center of the block, the recess being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, and is symmetric with respect to its horizontal center plane; and an upper pyramidal block which has a base portion and a pyramidal portion formed on the base portion, the pyramidal portion being in the shape of a right pyramid with a bottom in the figure of a regular quadrangle, and is disposed downward, the above components being arranged from bottom to top in the order of their description between a ram and a frame of a press, the lower pyramidal block being set on the ram or the frame; the lower guide block being set on the lower pyramidal block, the pyramidal portion of the lower pyramidal block being fitted into the lower pyramidal recess of the lower guide block, the lower base block being disposed at the center of the upper upside-down pyramidal recess of the lower guide block, the base of the upper downward pyramidal block being secured to the frame or the ram, as the case may be, the upper guide block being secured to the upper downward pyramidal block, the pyramidal portion of the upper downward pyramidal block being fitted into the upper upside-down pyramidal recess of the upper guide block, the upper base block being disposed at the center of the lower pyramidal recess of the upper guide block, the four slide blocks being disposed so as to slide along the pyramidal slopes of the upper pyramidal portion of the lower base block, the pyramidal slopes of the lower upside-down pyramidal portion of the upper base block, the pyramidal slopes of the upper upside-down pyramidal recess of the lower guide block, and the pyramidal slopes of the lower pyramidal recess of the upper guide block.
