Description

The invention relates to construction production and can be used to produce tubular products from concrete mixtures.

A known mold for pressing hollow articles of powder containing a conical sleeve, an elastic matrix, a core-forming core, a base, an insert, elements fixing the elastic matrix, a loading device (1).

A disadvantage of said pipe production apparatus is its low productivity.

An object of the present invention is to increase the productivity of a device and reduce the cost of pipes.

This goal is achieved by the fact that the installation is equipped with a frame structure with a loading device installed on it, connected by means of a cone with a cone, and a movable traverse with a supporting element fixed to it;

a support frame on which a stop is made, installed between the base and the forming core, rotation mechanisms and vertical movement of the forming core, and a vibrator installed in the cavity of the forming core, while the latches interacting with the grooves made on the base are mounted on the lower end of the conical holder.

In FIG. 1 shows the installation at the time of loading the pressed material; in FIG. 2 - the same at the time of pressing the material; in FIG. 3 - the same at the time of unloading the product ..

The apparatus for molding tubular products comprises a loading device 1, a frame structure 2, a movable cross-beam 3, an elastic matrix 4, a conical holder 5, a supporting frame 6, a vibration device 7, a forming core 8, a rotation mechanism 9, a device for

Installation works as follows. . . : ,,, ..-. :

. At the initial moment of loading the material (Fig. 1), the forming core 8 is in its lowest position, and the movable crosshead 3 is at that moment in a raised position above the conical ferrule 5. A loading device 11 is inserted into the space thus formed, which loading the material into the cavity of the elastic matrix A. Next, at the time of the start of loading, the vibrating device 7, the device for moving the forming core 10 and the rotation mechanism 9 are turned on. As the material is loading, the forming core 8 minutes while rotating and vibrating, rises upwards and enters the cavity in the liner 13, once ob- manner, it of particulate material tubular preform. Rotation of the core 8 is necessary for loading polymer fiber concrete. When loading conventional concrete mixtures, rotation of the forming core 8 is not necessary. At the moment of contact of the forming core 8 with the cavity of the liner 13, the loading device 11, the vibration device 7, the device for moving the forming core 10 and the rotation mechanism 9 are turned off.

At the end of the material loading, the loading device is removed to the side.

11. movable yoke 3 goes down

prior to the entry of its supporting element 16 in contact with the liner 13, the loading device 1 is turned on (see Fig. 2). Loading device 1 by means of t g 12

moves the conical ferrule 5 down vertically. Moving down, the conical ferrule 5 deforms the elastic matrix 4 in the radial direction, which in turn presses the material to the forming core 8. At the end of the pressing process, the loading device 1 returns the conical ferrule 5 to its original position. At the same time, the elastic matrix 4 due to the elastic forces

returns to its original position, forming a gap between the pressed product and the inner surface of the elastic matrix 4. After that, the movable crosshead 3 rises, and the forming

core 8 slides down to its original position. Then again, the loading device 1 is turned on for lifting, which, working synchronously with the movable traverse, raises by means of the link 12 and the clips

15 a conical ferrule 5 with an elastic matrix 4, a liner 13 and a base 14 above the compressed product remaining on the support 17 of the support frame b (see Fig. 3). Next, a special device (not shown in Fig.) The product is transferred to further processing (steaming) . After that, the loading device 1 is again turned on, which returns the conical ferrule 5 with the above elements to the original

position, and at the same time, the movable crosshead 3 returns to the loading position. After that, the loading device 11 is brought in and the cycle repeats.
