Description

The invention relates to the manufacture of ceramic products and can be used in the molding of products from building materials. A device for forming hollow brick and ceramic products is known, including a mouthpiece, cores making an oscillatory motion, and the vibration of cores arises under the action of induction currents of an induction solenoid coil 1. The closest technical solution to the invention is a belt press head containing a shell, mouthpiece, vibrator and shock absorber for compactors 2. However, in such devices, the vibration created inside the ceramic Classes is absorbed by its inertia and elasticity and is not transmitted to its outer layers, which reduces molding quality. The purpose of the invention is to improve the quality of molding. This is achieved by the fact that in the head of a belt press comprising a body, a mouthpiece, a vibrator and seals gel-absorbers, the head body is made up of sockets, one of which is rigidly fixed to the press, and the other is connected to the vibrator and the mouthpiece and is equipped with a knife along its axis. In the head of the bell of the housing can be interconnected by means of a parallelogram suspension, hinged on the press. FIG. 1 shows the proposed head; in fig. 2 shows section A-A in FIG. 1. The head of a belt press contains a vibrating bell 1 with a knife 2 rigidly attached to it, a mouthpiece 3 and a vibrator 4 directional oscillations and a fixed socket 5 rigidly fixed directly on the foundation. Vibrating 1 and fixed 5 sockets are connected by parallelogram suspension, elastic rubber frame 6 and spring shock absorbers 7. The back of the knife 2 is attached to the side walls of the vibrating socket 1 and passes through the entire width of the socket to the mouthpiece 3. Forward, protruding from the vibrating socket, part the knife

2 is located inside the fixed bell 5 along its entire length with a certain gap between it and the knife. A parcel suspension, connecting the sockets, is formed by four legs 8, the ends of which are hinged on opposite flanges of the vibrating 1 and fixed 5 sockets. Each suspension ha consists of two parts with left and right threads and a nut, adjusting the length of the rod,

The tightness of the joint of the sockets with the simultaneous mobility of the vibrating socket 1 relative to the fixed 5 is provided by a rectangular frame 6 of soft rubber placed in the grooves on the ends of the connecting flanges of the sockets 1 and 5.

The density of pressing the rubber frame 6 to the flanges, as well as the centering of the vibrating bell 1 relative to the fixed 5, is carried out by changing the length of the tongue 8.

The vibrating bell is driven by a vibrator of 4 directional vibrations fixed on the platform of the vibrating bell.

Through spring shock absorbers 7, by means of stop plates 9, the vibrating socket is connected to the base plate 10 of the fixed socket, which is rigidly attached to the foundation

The flanged head of the fixed socket is attached to the flange of the belt press cylinder.

When the vibrator is on, the vibrating bell 1 with the knife 2 fixed inside it and the mouthpiece 3 fixed to it vibrates in a vertical plane, which is transmitted to the clay mass. Moving from within the clay head to the mass is subjected to vibration from inside and outside. In a stationary bell, the vibration is communicated from inside by a knife vibrating with respect to it, in a vibrating socket, both by vibrating walls of the socket from the inside and outside, and in a mouthpiece by outside of the mouth of the vibrating mouthpiece.

With such a combination, the best, in comparison with separately used methods, the quality of the vibratory treatment of the clay mass is achieved and the duration of such processing increases.

The design of the head makes it possible to reduce the mass of its vibrating parts, and the attachment of the mouthpiece to the head simplifies it, since it allows you to do with only one movable seal,

The connection of the vibrating and fixed bells of the head through a parallelogram suspension through. the elastic rubber frame and the fastening of the fixed bell directly to the foundation improves the isolation of the stationary parts of the press from vibration.

The mechanism of transverse vibrations with an inertial drive in contrast to

a well-known eccentric drive, is more reliable in operation and allows the use of commercially manufactured directional vibrators (twin-shaft or built-in vibrators),

During the vibratory treatment of the clay mass, the svilins, formed during the passage of the clay through the press, are destroyed, and a more uniform structure of the clay bar is created.

At the exit of the mouthpiece, as a result of this, the strength of the brick and its grade increases.
