Description

Devices for manufacturing tubular concrete products are known in the form of a mold with a vibrating core and an iriver stamp. Other devices with a vibrating core and a vibrating form are also known.

Well-known and widely used in industry are installations for the manufacture of concrete and reinforced concrete products, which use pallet shops, pushers to move the molded products and load handlers for loading products.

In the proposed installation, the process of forming the product is accelerated and its design is simplified by combining the shape and core with a rigid diaphragm with openings for the passage of the stop rods. Thrust rods hold the freshly molded product while lowering the mold with the core. The coaxiality of the prigruz’s movement with the mold is ensured by the fact that they have the ability to vertically move on the heat pipe.

Figure 1 shows the proposed installation in cross section; in fig. 2 is the same in terms of.

The installation consists of a feeder / feeder, a dispenser 2, a vibrating dispenser 3, a pipe 4, a mold 5, a hollow core 6, a loader 7, a vibrator S and I of the puller W and a magazine 11.

Shell formation is carried out in the following sequence. Ready light concrete mix enters the hopper / feeder, from which it is fed into volumetric metering unit 2. After filling the metering unit 2 with the required volume of the mixture, the metering hatch automatically opens and the vibrating distributor 3 turns off. The annular space around the core 6.

After the dispenser is emptied, its hatch is closed and the vibrating separator 3 is turned on. At the same time, the hydraulic lever 19

No. 132525 ....- 2 begins to lower the loader 7. When the loader 7 comes into contact with the concrete mass, the vibrators 8 and 9. As the concrete mass compresses, the loader 7 descends to the test position. After that, the vibrators are turned off, the loader 7 rises to its original position, and the puller 10 pulls down the form 5 with the emptying device 6 rigidly connected to it 6. On the support rods x 20, the pallet 12 remains with the product 15. Simultaneously with lowering the form, the chain feeder is activated frame 13, which moves frame 14 to the distance required for stacking the pallet with the product; The next frame from the magazine 11 performs the same movement. After form 5 and frame 14 take the control position, node 13 turns off and on an actuator plunger 16 which moves the pallet with the workpiece with anvils 20 on the frame 14, and the thrust rods fed on the next pallet. Thereafter, the mold with the puncher is fed up and as soon as they take the control position, the cycle begins again. Next, the molded product is fed to the forks 17 from where it is moved to the trolley 18. The loaded trolley is rolled into the chamber for heat and moisture treatment.

Claims (2)

1. Installation for molding hollow lightweight concrete products, by pressing in a vibrating mold with a vibrating heart, using a prigruz and made in the form of an estrus pipe for feeding the mixture from the hopper and the mold located above the latter coaxially, characterized in that, in order to speed up the molding process and simplify the installation design, the form and the core are articulated between themselves by a rigid diaphragm with openings for passage through them of the stop rods, which hold the freshly molded product while lowering the form with the core. 2. The installation according to claim 1, in connection with the fact that, in order to ensure the alignment of the prigruz movement with the form, it is mounted with the possibility of vertical movement on the chute pipe.
