FIELD: manufacture of products of precast concrete and reinforced concrete from semi-dry construction mixes. ^ SUBSTANCE: the assembly has a vibrating table installed on the frame of the vibrating table, right-hand and left-hand guiding tables with the main and auxiliary dispensers installed on them. Guides with a carriage installed on them are fastened on the bed in its transverse axis and rear support. A punch and a matrix with an insert, having attracting permanent magnets for fixing the production bottom plate on it, coupled to the power cylinders are suspended from the carriage by means of movable plungers. The main magazine of the production bottom plates and the auxiliary magazine of the transport bottom plates with grippers of the latters in the form of disks with attracting permanent magnets are installed respectively before the vibrating table and behind the rear support in the longitudinal axis of the horizontal guides. The disks are fastened on the rods of the power cylinders. Manipulators for shifting the bottom plates are oppositely fastened on the cross ends of the carriage. The manipulators are made in the form of L-shaped cantilevers with attracting electromagnets. The insert forming the working space of the matrix has locks of the production bottom plates on the rear end in the form of permanent magnets. An opening for passage of the manipulator with the bottom plate is made in the rear support. The carriage is retained in the front and rear working positions by locks. Thickness S of the production bottom plate and the values of the coupling forces of the main or auxiliary gripper or of the bottomless matrix of the insert to the production bottom plate forming the working space are less than thickness S1 of the transport bottom plate and the values of the coupling force of each manipulator to the bottom plate by 3.5-6.5 and 1.2-1.5 times respectively. Distance T between the vertical axes of the main and auxiliary magazines of the production and transport bottom plates exceeds distance T1 between the vertical axes of the attracting electromagnets of the front and rear manipulators of the drive carriage. ^ EFFECT: enhanced quality of the molded products, enhanced labor productivity, reliability and quality of products, reduced labor content of the attendants, reduced power capacity and noise level. ^ 4 cl, 9 dwg |
