Method and device for producing stone moldings for masonry blocks, in particular sand-lime bricks, with adjustable mold walls

摘要

A method for producing stone moldings for masonry blocks, in particular sand-lime bricks, in which a) in at least one mold space (2) which is delimited by at least two, preferably four, mold walls (10, 20, 30 30), in a first production process, stone moldings of a first In a second production process, stone moldings of a second block format are produced by means of at least one pair of press rams (5 and 6, 7 and 8) movable against each other in a pressing direction (P) in the forming space (2) between the mold walls (10, 20, 30, 40) b) wherein between the first production process and the second production process at least one of the mold walls (10, 10 and 20) of the mold space (2) by means of an associated adjusting drive (11, 11 and 21) is adjusted, so that the Cross-section of the mold space (2) perpendicular to the pressing direction (P) or at least one dimension (B1, B2) of the mold space (2) perpendicular to the pressing direction (P) in the first Manufacturing process and the second manufacturing process, and thereby preferably the stone format, are different.
