Description

This invention relates to the manufacture of precast concrete products and concrete glands. It is known a device for vibrating rods of products from concrete mixes, comprising a vibrating table with a covering frame, mounted on elastic supports, a form and a stamp, the elastic supports being made with tightening elements, and a stamp with loading cylinders 1. The closest technical solution to the proposed is a device for forming articles from concrete mixtures, which, installed on the base by means of elastic supports, is movable with a vertical oscillator and guides covered by pins g horizontal traverse with punches, multi-seat form with trays mounted on a movable frame, hydraulic jacks, the ends of the rods of which are in contact with the horizontal traverse 2. A disadvantage of the known devices is their large metal intensity and insufficient intensity of the process. ow seals The purpose of the invention is the reduction of metal intensity and intensification of compaction processes. This goal is achieved by the fact that in a device for forming articles from concrete mixtures, a movable frame installed on the base by means of elastic supports with a vertical vibration exciter and guides covered by pins of a horizontal cross bar with poles is multi-shaped with pallets mounted on a movable frame hydraulic jacks, the ends of the rods of which are in contact with the horizontal. traverse, the latter is supplied with bushings and wedge clamps, the ends of the rods of the hydraulic jacks you olneny with windows and are arranged in the sleeves, the hydraulic jacks are mounted on the movable frame, and wedge clamps are installed in the rods windows. The drawing schematically shows a device for molding concrete products, general view, section. A device for forming a product of concrete mixtures consists of a movable frame 1 with hydraulic jacks 2 and guides 3. Hydraulic jacks 2 are equipped with rods 4, and guides

3 calibration washers 5. On the rods

4 and guides 3 are respectively fitted with sleeves b and trunnions 7 of horizontal traverse 8 on which punches 1 are fastened 1. Into holes 10 of rods 4 wedge clamps are inserted And, On the movable frame 1 there are pallets 12 with on-board equipment 13 and exciters 14 of vertical-directed oscillations.

A device for molding concrete mixes as follows is operated.

When elevated, the crosspiece 8 with the punches 9 on the pallets 12 between the on-board equipment 13 is placed a certain amount of the mixture, such as phosphate concrete. After the concrete is laid using the jacks 2, the traverse 8 is moved down. The punches 9 in this case enter between the on-board rig 13 and press the concrete. Simultaneously with pressing, exciters of 14 oscillations of the moving frame 1 are turned on, while ®®4 трав horizontal traverse is pushed all the way to the trunnion b in washers 5 and the concrete mix is compacted. After the molding process is completed, traverse 8 will be lifted up together with punches 9. Sub-platforms 12 are removed from the movable frame 1 together with the molded parts and supplied to the heat-treating portion thereof. On the movable frame is installed next

tray 12. Next, the process of forming products is repeated.

The proposed device makes it possible to reduce the metal intensity and intensify the compaction processes.
