Method and device for producing brick blanks for masonry bricks, in particular sand-lime bricks, having adjustable mould walls

摘要

Method for producing brick blanks for masonry bricks, in particular sand-lime bricks, in which method a) in at least one moulding space (2) which is delimited by at least two, preferably four, mould walls (10, 20, 30 30), brick blanks of a first brick format are pressed from a primary material in a first production process, and brick blanks of a second brick format are pressed from a primary material in a second production process, by means of at least one pair of press rams (5 and 6; 7 and 8) that are capable of being converged in a pressing direction (P) into the moulding space (2) between the mould walls (10, 20, 30, 40); b) wherein, between the first production process and the second production process, at least one of the mould walls (10; 10 and 20) of the moulding space (2) by means of an assigned adjustment drive (11; 11 and 21) is adjusted such that the cross section of the moulding space (2), perpendicular to the pressing direction (P), or at least one dimension (B1, B2) of the moulding space (2), perpendicular to the pressing direction (P), and on account thereof preferably the brick format, are dissimilar in the first production process and in the second production process.
