Abstract

FIELD: building materials industry, production of building pieces from semidry mixtures by hyperpressing. SUBSTANCE: method provides for production of moulding mass, its loading into press-moulds, fulfillment of pressing operation with formation hollow cavities in building blocks, knocking-out of fresh moulded blocks, their lifting and transportation in accordance with process route, for example, to positions of heat treatment, stockpiling. Method allows to produce blocks of 140 - 160 mm height and 400 - 600 mm size with thin shape of "pit-bulge" type on block base used for mortarless block-laying. Press-mould is made two-sectional and knocking-out mechanism, that ensures reliable extraction of blocks in conditions of hyperpressures. In the case presence of new ties between press-mould members simplifies design, create conditions to realize optimal mode of pressing without increase of press and other facilities power consumption. Production line for realization of the method is composed of mounted in process sequence amplifying module, loading apparatus, moulding post, press and press-mould, reloader, pushing mechanism, receiving and stockpiling apparatuses. Line has collapsible mechanism, that has intermediate carrying building blocks member - reception troughs and base member - tray-collector, that are capable to be engaged with facilities of production line on corresponding process positions. Line also has mechanism of delivery of intermediate carrying members - receiving troughs for building blocks. EFFECT: improved process of blocks production, simplified design of equipment, increased productivity, quality and reliability of production. 2 cl, 30 dwg

The invention relates to the production of building products from semi-dry mixtures by hyperpressing. The method includes preparing the molding material, loading it into the mold, performing pressing to form voids in the building beams, pressing out the freshly formed block, removing it and transporting it according to the technological route, in particular, to the heat treatment position, stacking. Distinctive features of the method are aimed at solving the problem of manufacturing blocks of considerable height 140 - 160 mm and dimensions 400 - 200 mm, having a thin relief on the bases of the type "protrusion - groove", designed for implementation of mortarless masonry. The mold is made of two sections and has a construction of the extrusion mechanism, which ensures reliable extraction of blocks under hyperpressure conditions, while new connections between the mold elements simplify the design, make it possible to implement the optimal pressing mode incorporated in the method without increasing the press power and energy intensity of the equipment. The line for implementing the manufacturing method comprises an amplification module, a loading device, a molding station, a press and a mold, a reloader, a push mechanism, a receiving and stacking device installed in a technological sequence. The line is equipped with a collapsible device containing an intermediate supporting building blocks element - receiving trays and a basic element - a storage pallet, which are made with the possibility of interaction with the line equipment at the corresponding technological positions. The line is also equipped with a mechanism for the transverse supply of intermediate load-bearing elements - receiving trays for building blocks, and the implementation of individual functional devices, the construction of the line is aimed at increasing productivity, quality, reliability in the manufacture of building blocks having the above-mentioned features, and these indicators are achieved in line with a comparative simplicity of design.
