RU2723329C1 - Device for cutting of raw common solid clay bricks - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention relates to machine building for molding articles from clay with removal of excess parts by cutting. Device in the form of a guillotine for cutting of raw solid common clay bricks includes a frame with a table, a portal and a retainer. Moreover, the table contains adjustment stops. Portal consists of two cylindrical posts, left and right, installed on the frame and interconnected by a beam, along which moves on bushings the slider with spatially rigid plate shaped knife, fixed with bolts on slider and made replaceable. Movement of the slider is transmitted from a lever swinging on the hinge via a clevis connected by hinges to the lever and the slider. Retainer is made with possibility of engagement with the pin ensuring retention of the slider in the upper position.

- field of technology to which the invention relates

The invention relates to the field of engineering for the molding of clay products with the removal of excess parts by cutting.

- prior art

A known method of obtaining raw shaped full-bodied clay brick, in which are formed the facial shaped - curly, curved surface of the brick by cutting. (SU 1150083 A1 (Khokhlov N.A.), 04/15/1985)

A known complex for cutting an article in a plastic state is that the front surfaces of an article in a plastic state are formed by cutting with curly knives. (RU 2333097 C1 (VASILIEV O.N.), 09/10/2008)

A device is known in the form of a guillotine with a drive and a blade knife for cutting raw raw shaped ordinary solid clay products in order to obtain raw shaped full solid clay products (GB 652416 A (DONALD JOHN DAVIDSON ET AL), 04/25/1951)

It is known that the drive is manual (SU 2138 A1 (ZHAVORONKOV M.A.), 09/15/1924)

A device is known for cutting an article containing several interchangeable spatially rigid lamellar knives (SU 408807 A1 (STAINS OF SILICATE CONCRETE OF AUTOCLAVE SOLID), 11/30/1973)

- disclosure of invention

The purpose of the invention is the receipt of shaped corpulent clay bricks from ordinary corpulent clay without changing the main technological process for the production of corpulent bricks.

Raw raw ordinary clay brick, located after molding on drying, is cut with curly knives of a guillotine with a manual drive, stacked in stacks for drying, and then fired.

it is used in the brick facade masonry of buildings, in accordance with the architectural design (project) of the construction object and the nomenclature of figured brick laid in the project.

The objective of the invention is to expand the product range of existing brick factories, producing ordinary full-bodied burnt clay brick, in terms of the production of small (sufficient) volumes of various shaped bricks for facade masonry of buildings (cornices, plinths, platbands, etc.) without changing the main technological process enterprises. Shaped bricks, with the simultaneous use of selected ordinary ones, are reviving the option of building buildings with unplastered brick facades, which have now lost their high aesthetic qualities, which reduce the cost of facades, and, accordingly, a significant part of the operating costs for maintenance (plaster repair, painting). The proposed technology can be used in restoration work on complex brick buildings, including architectural monuments in the preparation of shaped wall material.

- implementation of the invention

1. A study of the practice of brick factories, showed that there is a fairly large variation in the plasticity of the clay mass in the raw standard brick laid for drying in drying sheds. After gaining the necessary strength (mainly 0.5-1.5 days) during drying, the raw brick using the device (guillotine) is trimmed. The resulting figured brick is collected in stacks for further drying, and the trimmed remains of the original raw brick are returned to the beginning of the raw material production chain, for example, they are discharged into the bunker of a clay baler. In an experiment conducted at 3 plants, the raw material ductility optimal for cutting was established. A device for raw plasticity probe was manufactured and graduated.

2. The design of the guillotine includes a frame 1; table 2 with stops 3; portal 4, consisting of two cylindrical racks, left 4a and right 4b, mounted on the frame 1 and connected by a beam 4c, along which a slider 6 moves on the bushings 5, with a spatially rigid plate shaped knife 7, bolted to the slider and made interchangeable, while the movement of the slider 6 is transmitted from the lever 9 swinging on the hinge 8, through the earring 10, connected by the hinges 11 with the lever 9 and the slider 6, the latch 12, made with the possibility of engagement with the pin 13, ensuring the holding of the slider in the upper position. Raw brick 14 for trimming is placed on table 2.

The guillotine works as follows.

In the initial position, the slider 6 with the knife 7 is fixed in the upper position. The raw brick of ordinary brick 14 is placed in the desired position on the table 2 along the marking lines and adjustment stops 3, preventing its horizontal sliding. The guillotine operator disengages the latch 12 from the pin 13 and moves the lever 9 downward with muscular force, which transfers the force through the earring 10 to the slider 6 with the knife 7. In this case, after the cutting edge of the knife 7 contacts the upper face of the raw brick 14, the clay part is cut off. brick mass, ending when the cutting edge of the knife 7 reaches the surface of the table 2. The finished raw shaped brick remains on the table 2, and the cut-off parts of the clay mass fall into the container mounted on the floor, under its own weight or with the help of the operator. Next, the raw shaped brick is stacked in piles to continue drying, and at the end of it is fired. To obtain the angular shapes of shaped bricks, after changing the guillotine, the cut is carried out repeatedly, but now on a different facet of the brick.

Claims (1)

A device in the form of a guillotine for cutting raw raw ordinary solid clay bricks, characterized in that it includes a bed with a table containing adjustment stops, a portal consisting of two cylindrical racks, left and right, mounted on the bed and connected by a beam, on which on the bushings the slider moves with a spatially rigid plate-shaped knife fixed with bolts on the slider and made removable, while the movement of the slider is transmitted from the lever swinging on the hinge through the earring connected by the hinges with the lever and the slider, a latch made with the possibility of engaging with a pin, providing holding the slider in the upper position.
