Description

The invention relates to devices for forming tubular articles from concrete mixtures by the method of centrifugal rolling.

The purpose of the invention is to increase reliability and durability.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section of YYD in FIG. 2; in fig. 6 — node I in FIG. 2

The device comprises a drive forming shaft 1 with a cantilevered non-forming part 2, treadmills 3 and a forming part 4. The forming shaft 1 is mounted on a bed 5 in a fixed support 6 and a movable 7 made on a carriage 8 horizontally movable along the axis of rotation of the forming forming shaft 1. Device also contains a form 9 installed on the treadmills of the drive forming shaft 1 placed in its cavity, the feeder 10 and the drive P. The fixed support b is made with a vertical stop 12, limiting the vertical movement of the console The left non-forming part 2 of the forming shaft 1 in its non-working position. A gap S is provided between the cantilever non-forming part 2 and the stop 12 of the fixed support 6. The movable support 7 is made in the form of a horizontal beam 13 and fixed relative to the uprights 14 of the frame 5 by means of mechanisms 15 of vertical displacements of the beam 13 arranged symmetrically to its transverse axis. The horizontally movable carriage 8 is provided with height-adjustable lugs 16, on which horizontal bar 13 supports itself with its brackets 17. The mechanisms 15 of the vertical displacements of the horizontal beam 13 are made in the form of drive wedges 18 with working part 19 and connected to the power cylinders 20. Drive wedges 18 mechanisms 15 are in contact with the horizontal grooves 21 of the uprights 14 of the frame 5.

A device for forming tubular concrete products works as follows.

On the drive forming shaft 1, located console in a fixed support 6 and supported by the non-forming part 2 in

the stop 12, limiting the vertical movement of the cantilever, pulls the mold 9. Then moves along the axis of rotation of the forming shaft 1 horizontally

a movable carriage 8 with a movable support 7, while the latter is connected with the cantilever end of the forming part 4 of the drive forming shaft 1. After this, the power cylinders 20 of the mechanisms 15 of the vertical displacements of the horizontal

beams 13. Power cylinders 20 move drive wedges 18 that are horizontally located in beam 13 symmetrically to its axes, which, in contact with their working parts 19, with grooves 21 posts of 14 beds 5,

smoothly raise the movable support 7 with the end of the forming part 4 placed in it to the horizontal position of the drive forming shaft 1 and fix the movable support 7 relative to the posts 14 of the bed 5. In this case the cantilever

the end of the non-forming part 4 moves away from the stop 12 and a gap S is provided between them. After this, the mold 9 is installed on the treadmills 3 of the forming shaft 1. The feeder 10 is inserted inside the mold 9, the drive 11 of rotation of the forming shaft 1 is turned on, and into the cavity mold 9 is supplied with a concrete mix, which is distributed inside the mold 9 due to centrifugal forces, then compacted by running by a drive forming shaft 1. After molding is completed, the drive 11 is turned off, and mold 9 is raised above the drive forming shaft 1. The power cylinders 20 me anizmov 15 that move drive wedges 18 from the slots 21, 14 in the struts 13 of the movable support beam 7,

which, together with the end of the forming part 4 of the drive forming shaft 1, is smoothly lowered and supported by the brackets 17 of the beam 13 on the height-adjustable supports 16 of the carriage 8. At the same time, the cantilever end of the non-forming part 2 of the shaft 1 smoothly rises until it stops 12 said console 2. A horizontally movable carriage 8 moves along the forming axis, after

which form 9 with the molded product is brought out of the device for further processing in accordance with the process. J8 15 20
