The invention relates to the production of concrete and reinforced concrete tubular products by extrusion.

The purpose of the invention is to ensure the manufacture of socket pipes.

FIG. 1 shows the installation, general view; in fig. 2 shows section A-A in FIG. ; in fig. 3 shows a section BB in FIG. one; in fig. 4 — installation at the end of molding, general view.

The installation includes a molded part 19 of the pressing chamber 4 supported on a base-molded bell-shaped part under the action of a reactive force acting on the compaction of a mass of concrete. The compaction enhancement is regulated within certain limits by the brakes 16 located on the carriage 2, the shoes 17 of which, abutting against the rail head 26, create the necessary resistance to movement. Thus, the cylindrical part of the product is molded. At this stage

1 1 carriage 2 with 10 mounted on it conical section 7 goes out

from the end of the pressing chamber 4, the supply of concrete from the feed hopper 3 is stopped, the filling of which is designed to form a single product. With the end of the sealing conical section 7, the concrete has disappeared and the reactive force disappears.

feed hopper 3, pressing chamber 4, in which a screw feeder 5 is placed with a cylindrical section 6 and a detachable connection connected with it

cylindrical shank 8 connected through anti-vibration gasket | 9 with a fixed hollow core, 10 m, and an exciter that is mounted on the shaft of the driving motor 11, in the form of a vibrajet 2 stops. Removing the remaining part in the concrete of the iO emptying unit is performed by switching on the displacement drive. The simultaneous action of vibration and rotation of the screw blades 23

torus 12. The drive motor 11 hosts 20 screw feeders 5 when braking the backbone of the cavity of the void former 10, and vibrator 12 in a cylindrical shank 8. Carriage 2 is rigidly connected to the yoke 13, in which the dimensions are 6, the cylindrical section 6 of the screw feeder 5. On the carriage 2, the rotational drive 14 and the drive 15 of the screw feeder 5 are installed, as well as the brakes 16 with the shoes 17. On the base 1, the clamping constator 10 is mounted, the retainer 18 of its supporting carriage 2 creates a vibrocompression condition that provides good quality of manufacture of reinforced concrete pipes, including pressure pipes.

The end of the molding is as follows. When the core former 10 is removed from the concrete, the pressing chamber with the hooks 22 open and the quick-release locks 21 are passed on to subsequent technological operations, and in its place

neither The pressing chamber 4 is designed as a fix. Carriage 2 at this

The cylindrical shell made up of the longitudinal section has a rear conical bell-shaped part 19, is mounted on the fixing supports 20 and secured with quick-release locks 21 and hooks 22. On the outer surface of the sealing conical section 7 of the screw feeder there are screw blades 23, and on the outer side of the Ivsr. of the cylindrical section 6 - screw blades 24. The hooks 22 are fixed on the support 25 mounted on the base 1.

The installation works as follows.

The assembled extrusion chamber 4 with reinforcement 26 is installed on the fixing supports 20 and fixed with quick-detachable

the moment is in the extreme left position. The hopper 3 is refilled with concrete. Then the actuator 15 is switched on and the carriage 2 is moved to the right. The void & enters the hole of the 35 Tsa extrusion chamber 4 of the extrusion, with further movement reaches its socket part 27 and beyond its limit stop, after which the void former is fixed with a fixture 18, and the cycle repeats.

Claims (2)

1. An installation for the manufacture of products with through longitudinal cavities made of concrete mixes, which is supported on the basis of 21 locks, and from displacement in the axial position -. The carriage with the feed bin and its expansion — by the hooks 22, located on the support 25. From the loaded feed bin 3, the concrete mixture is screw blades 24 of the cylindrical section 6 of the screw connector 5, and is fed to the socket part 19 of the pressing chamber 4 with screw screws blades 23 of the conical section 7 of the shnekovy feeder 5. The hollow core W is fixed by a latch 18 and does not participate in the rotation until the socket part 19 of the pressing chamber 4 is completely filled with concrete, as well as after entering it into the concrete due to forces Eni about concrete. The drive motor 11 is turned on. Further filling is followed by the entry of the core-forming agent 10 in the screw feed replaced in the pressing chamber with a sealing conical section connected through a vibration-isolating pad with a fixed core-forming agent and mounted on the drive shaft 50 motor oscillation pathogen, characterized in that, in order to ensure the manufacture of bell-shaped tubes, the carriage is provided with a yoke, a screw feeder - a cylindrical section arranged therein, connected with a detachable connection with a sealing section, and the latter pressing - in the form of a composite of the longitudinal sections of the cylindrical shell with the rear conical socket part, the preformed socket part 19 of the pressing chamber 4 under the action of reactive force acting from the compacted concrete mass. The compaction enhancement is regulated within certain limits by the brakes 16 located on the carriage 2, the shoes 17 of which, abutting against the rail head 26, create the necessary resistance to movement. Thus, the cylindrical part of the product is molded. At this stage sealing conic section 7 exits giving concrete disappears reactive power and carriage 2 is stopped. Removing the remaining part in the concrete of the iO emptying unit is performed by switching on the displacement drive. The simultaneous action of vibration and rotation of the screw blades 23 The screw feeder 5, when braking, the waste screw feeder 5, when braking, the waste carriage 2 creates the conditions for vibropressing, which ensures a good quality of production of reinforced concrete pipes, including pressure pipes. The end of the molding is as follows. When the core former 10 is removed from the concrete, the pressing chamber with the hooks 22 open and the quick-release locks 21 are passed on to subsequent technological operations, and in its place   fix. Carriage 2 at this the moment is in the extreme left position. The hopper 3 is refilled with concrete. Then the actuator 15 is switched on and the carriage 2 is moved to the right. The void & enters the hole of the 35 Tsa extrusion chamber 4 of the extrusion, with further movement reaches its socket part 27 and beyond its limit stop, after which the void former is fixed with a fixture 18, and the cycle repeats.
