MACHINE FOR PRODUCING WALL BLOCKS Russian patent published in 1995 - IPC

FIELD: building engineering industry. SUBSTANCE: mechanism of lifting the mold and the punch-matrix is made as two symmetrically mounted sections connected between themselves by U-shaped lever, disposed below the upper end of the mold, hinged on the machine frame and connected with the mold with the aid of flexible tractions. The mechanism of withdrawal of the punch-matrix has a hinged pusher connected with T-shaped frame by means of a fixing stand and two guiding rods. The T-shaped frame is connected with the machine frame with the aid of a three-link parallelogram system. The flexible tractions are secured in the center of gravity of the mold. The mass of the counterweight and the length of the U-shaped lever depend on the mass of members, the section radius, the lever arm and ave determined by the relationship given in the invention description. EFFECT: enhanced efficiency. 2 cl, 5 dwg
