CUTTING DEVICE OF THE BULK CELLULAR CONCRETE Russian patent published in 2007 - IPC B28B11/14 

FIELD: construction industry; cutting devices for the bulk cellular concretes.

SUBSTANCE: the invention is pertaining to the field of construction industry, in particular, to production of construction materials and may be used in manufacture of the products out of the foam mortar by cutting-off. The technical result of the invention consists in the improved production process of the foam mortar blocks cutting-off, accuracy of the foam mortar blocks cutting-off to the preset overall dimensions due to reciprocal movement of the cradle with cutting components and reduction of their dynamic effect due to distribution of the moment of forces, and also in the increased reliability, reduction of the metal consumption and simplification of the design. The substance of the invention is determined by the combination of the significant features of the device containing the base, the cradle with the cutting components, the traveling platform with the clampers and the underpan, the electrical drive. The base is made in the form of two rigidly interconnected parts located bevel way to each other forming by the planes the dihedral angle from 90° up to 180°. At that in one part of the base in the guides there is the cradle with cutters capable of the reciprocal motion, and in its other part there is the counterweight, the electrical drive linked to the cradle through the crank-connecting rod gear placed in the plane of its movement. At that the base is made with possibility of gyration around the axis passing through its gravity center and pivotally linked to the poles of the stand having the paired limiters of its position. The guides of the cradle motion with the cutting components on the base are made in the form of the symmetric pairs of the roller-supports, and its cutting-off components made in the form of the strings are consolidated by the brackets at the preset pitch on the opposite sides of the cradle with possibility of their stretching by nuts.

EFFECT: the invention ensures the improved production process of the foam mortar blocks cutting-off, accuracy of the foam mortar blocks cutting-off to the preset overall dimensions, reduction of their dynamic effect, the increased reliability, reduction of the metal consumption and simplification of the design.
