Description

The invention relates to devices for forming building products by rolling and can be used in the construction industry.

The purpose of the invention is the molding of grooved products of a radial profile, grooved products of a radial profile with technological openings, as well as both at the same time.

Figure 1 shows a section of the installation in front; figure 2,3 and 4 - section aa in figure 1.

The installation consists of a mold, which is a structure consisting of two prolfrrm 1 (Fig. 3) or their combination (Fig. 2), (Fig. 4), corresponding to the product profile and connected by a flange 3 with hinged bolts 4. Corner the recesses of the flanges 3 when connecting the half-molds 1 or 2 form grooves 5 for the entire length of the mold, which include the free ends of the vertically arranged flanges 6, fixed to the hub 7. The hub 7 on the bearing 8 is mounted on the shaft 9 of the carrier disk 10 with sealing rollers 11. The hub 7 with sides b has the possibility of vertical return for translational movement together with shaft 9. For forming products with technological openings, each half-mold 2 (Fig. 4) is made of two hinged sides 12 and a base 13, which carry the required profile openings 14 with a given step.

Installation works as follows.

On the basis of the established form, which is a prefabricated structure consisting of two half-forms 1 (for forming tray products of a radial profile, Fig.3), or two half-forms 2 (for forming tray-shaped products of a radial profile with technological openings, Fig. 4) or half-molds 1 and 2 (for forming tray products of one or another form at the same time, Fig. 2), connected by a flange 3 with hinged bolts 4, then inserted into the mold until the lower parts of the forming rollers 11 come into contact with the lower edge of the mold, carrying a disk 10 with rollers eleven and sides 6 with the ends inserted into the grooves 5 by moving the shaft 9 from top to bottom, while the size of the side 6 from

the surface of the mold to the forming rollers corresponds to the thickness of the molded product.

Then, the rotation drive of the shaft 9 is turned on, and a moldable mixture is fed into it through it, which is sealed by the forming rollers 11. Achieving the ultimate compaction of the mixture is characterized by extrusion of the mixture upwards, after which the shaft 9 of the carrier disk 10 with the forming rollers 11 begins to rise at the required speed. in this case, the sides b, together with the hub 7, carried upwards, divide the mouldable pipe into two halves (tray). The dismantling of finished tray products without openings is done by releasing the hinged bolts 4 with the subsequent half-mold connector 1, and the stripping of products with technological openings is done by releasing the hinged bolts 4 and deploying the hinged sides 12.

reciprocating movement and made in the form of a carrier disk mounted on a vertical shaft, on which sealing rollers are mounted using axes, and a cylindrical shape, characterized in that. that, in order to ensure the formation of grooved articles of a radial profile, the shaft is made with two diametrically arranged sides fixed on it with a hub on the bearing, and the form is made of half-shapes connected by hinged bolts along the flanges, and with grooves that are formed by angular recesses of the latter on the entire length and in which the free ends of the sides are placed.

2. The installation according to claim 1, with the exception that, in order to form products with technological openings, at least one half-mold is made with folding sides, a base and openings on its inner surface, having a narrowing from the side to the top and a curved surface along the radius of the moldable
