Description

The invention relates to devices for the manufacture of pipes made of concrete and the like of materials in which the molding of a formable material is produced by vibration with the installation of a source of vibrations inside the core forming the cavity of the pipe.

Distinctive feature

The proposed pipe making machine is that the mold forming the outer contours of the tube is rigidly fastened to the table, which is mounted with the possibility of horizontal movements, for transmitting vibrations to the concrete from the core through the above-mentioned form.

In the schematic drawing of FIG. 1 shows two variants of the device: the left side (from the axis of symmetry) depicts a machine in which the pressing upper ring is movable in the vertical direction during the molding of the first block; on the right (from the axis of symmetry) there is a variant of the machine, in which, when the pipe is molded, the pressing ring is stationary, and the table with the form fixed on it can move in the vertical direction.

FIG. 2 shows a variant of the machine with a pressing ring moving in a horizontal direction.

The machine consists of the following main parts:

1) an internal form (core) / with a vibrator 2 rigidly fixed in it, transmitting circular horizontal oscillations to the form;

2) the external changeable form, fixed on the table 4, freely oscillates in the horizontal plane on the hinged racks or hangers 5 and perceives the oscillation from the form /;

3) an annular stamp 6, the profile of which repeats the inner contour of the top of the forming pipe;

4) Table 7 with an edge 8, the height of which should correspond to the amount of concrete precipitation during the pressing together with vibration.

For the manufacture of the pipe, the mold 3 is rigidly fixed on the table 4, and the core / is installed depending on the thickness of the wall of the pipe, the presence of reinforcement and the composition of bethen or at the bottom of the form (5 and during the forming process, lift the table 4). , or set motionless in the upper position indicated by point-yrom in Fig. I. After the vibrator is turned on, concrete is fed into the ring gap, between the forms, where it is compressed by vibration, the filling of the mold is stopped, manually removed OR mechanically surplusETOH plo1skostyu flush with the section 4 and m is produced together with concrete compaction by vibration.

The pressing can be carried out either by an annular stripe 6, which is fixed on the traverse 5, moving in the guides ((1, 1-left-half) or with an inadvertent ring pin by lifting the table 4, which in this case is attached to its supporting structure , movably in the guides // (Fig. I - the rights of the head). At the same time, table 7 must also have a vertical time). together with the table 4.

When arranging a lifting table 4, an annular stamp can be made mobile in a horizontal PLANE, as indicated in FIG. 2. With two / Kenya rings; i; oro stamp on the form at the same time: an excess weight will be removed over the form; in the case of the reverse displacement with the scraper 12, the surplus of G.: the horn shifts into shape. By .:; i h i i and; and pr e cso in a to and in i-t6 p a then p

they turn off, the core U is lifted upwards and on leaving it from the pipe they lower table 4 or raise the finger stamp. After that, the fabricated pipe, together with the mold 3, is removed from the table 4 and transported to the aging place, where the mold 3 is removed from the pipe for reverse vibration to the vibropress. When the finished pipe is removed from the table 4, the table 7 is lifted or when the table is stationary 7, the form 3 with the pipe is moved to the side on the movable platform of the table 4. The finished pipes should be transported with an ayuddone attached to the pipe 3. Smooth and flared pipes move without gy. ddon due to the adhesion of concrete with (jupmo 3.
