Abstract

Purpose of equipment for the molding of products used primarily in irrigation and drainage construction for the installation of manholes for irrigation and drainage systems. SUMMARY OF THE INVENTION: The installation consists of a rotary table, a form, a vibrocord, a movable cross beam and a lower hydraulic press. axles, fixed on the fixed part. 5 il.

Description

The invention relates to equipment for molding articles used primarily in a land reclamation system: a device for viewing wells of irrigation and drainage systems.

A device for making hollow products from concrete mixtures is known, as well as a device for molding.

But these plants are not suitable for forming thin-walled products from concrete mixtures reinforced with fiber, due to the absence of a rotary table, which is necessary for uniform loading of concrete mixtures reinforced with fiber into the annular cavity.

Closest to the proposed technical design solutions is the SM-210K machine, which contains a rotary table with a form installed on it and a vibrating core.

However, the machine is not suitable for the manufacture of thin-walled annular products made of concrete mixes, reinforced with fiber,

since in it the annular cavity between the shape of the force and the vibrating heart does not allow the mixture containing the fiber to pass without its hanging.

The purpose of the invention is to ensure uniform loading of concrete mixes into the annular cavity.

This goal is achieved by the fact that the rotary table is made of a composite of fixed and rotary parts, the latter of which is freely mounted on the fixed part with the help of a roller support and is equipped with a drive for its rotation around a vertical axis fixed on the fixed part.

Figure 1-5 schematically shows the installation, General view.

Form 4, mounted on the transport and transmission carriage 7 with elements 5 and 8, is fed into the press working area on the grippers 14.

The mobile yoke 6 by the actuator 10 is raised up, the trolley 7 returns the eaten

s

from the initial position. The traverse 6 is lowered down and the form 4 is placed on the pallet 9. The traverse 6 is lowered lower into the loading position of the mixture. The rotary table drive 16 and the vibrators located on the core cover turn on. The mixture is loaded. Traverse 6 is lowered, providing pre-pressing from above. When the specified pressing force is reached, the drive 10 of the crosspiece is turned off, after which the force pressing from the bottom is carried out by means of a hydraulic cylinder 15 (Fig. 2).

At the end of pressing from the bottom, the core 3 with the form 4 will take the upper extreme position. The grippers 13 by means of hydraulic cylinders will fix the pallet 9 and the form 4 in the upper position. The hydraulic cylinder 15 will move 0 to its original position along with the core 3. The mobile yoke 6, lifting up, will take the shape 4 on the jaws 14. The grippers 13 will release the pallet 9 with the shape 4 and the molded product. The mobile yoke 6, moving down, sets the form 4 on the second carriage, freeing up the grippers 14. The cart with the form and the product moves to the unloading area.

The installation contains a skeleton 1 on which a rotary table 2 is installed, grips 13 with hydraulic cylinders, two columns with a lead screw 11 located diagonally, and two columns with smooth guides 12. In the upper part of the column they are connected by a fixed traverse 21. The columns are fixed movable traverse 6.

Table 2 consists of a hydraulic cylinder 15 installed inside it and a rotational drive 16.

A core is installed on the rotating part of the table through elastic elements.

3. On the lid of the core 3 at an angle of 120 vibrators are mounted with horizontal axes of rotation.

The core 3 is installed with a pallet

9 with the form 4 located on it.

On the movable cross beam 6, the clamps 14 and the punch 22 are fixed. The cross beam 6 (FIG. 4) is moved by the actuator 10 through the gears 17 and 18, the running nut 20,

which, when rotated, moves along the spindle screw 11. The gimbal nut 20 is connected to the body of the cross member 6 via bearings

nineteen.

The end surfaces of the mold 4 and the punch 22 are configured to allow the product to be fixed when installed one upon the other during installation.

Figure 5 shows the core 3 and form 4, which together form

tapered surfaces of the molded product and the pallet 9. The taper of the inner surface of the form 4 is greater than the taper of the outer surface of the core 3.
