SU69834A1 - Eccentric Press for Two-sided Horizontal Brick Compression - Google Patents

Description

Presses are known for two-sided horizontal pressing of bricks simultaneously in a variety of shapes, using a central rotating shaft with e-centers fitted on it, designed to act radially. placed punches in fixedly mounted molds.

The proposed press of this type is characterized in that the molds are mounted with the possibility of free movement in the radial direction during the pressing of the mass in the mold, and the outer punches of each shape are fixed on the table motionless.

FIG. 1 shows a press in section along the vertical axis; in fig. 2 shows a section along the horizontal axis of the dies and in FIG. 3 - section of the form with a nutrient box in a perspective view.

The bed / on which the supports 2 are rigidly interconnected, the table 5 and the frame 4 as a whole constitute the press casing. In frame / and frame 4 in nentre still

Axis 5 is fixed by means of a pin b and a nut 7. On a fixed axis 5, the drive rotates - gear 8, resting on support bearing 5 and rigidly connected with tongues, wedges and similar devices with a rotating rim W to control the work of the tenant 1, a cam lock 12 serving to return to the initial position of the mold / S, an eccentric of the pressing 14, a cam disc 15 serving to return to the initial position of the movable punch 16, and gear 17. Through the gears 17 and 18, the movement is transmitted to the auxiliary shaft 19, the cat Ory through the gears 20 and 21 rotates the shaft 22 with the disk 23 mounted on it,

The press has twelve forms with nutritious boxes 24, twelve moving punches 16 and the same fixed punches 25. Moving punches 16 are provided with rollers 26.

When the press is working, the crushed clay is conveyed to a conveyor or other device in order

moving bunker 27. The rotating hopper 23 of the bunker contains clay in all chutes 28 of the press. The press operates in such a way that the mold performs all the operations sequentially, and the pressed brick is successively removed from each mold.

The pressing process is as follows. Clay from the chute 28 cannot flow into all forms at once, since, thanks to the cam jaw 12, the molds can only be alternately in the backfill position, as indicated on the left in FIG. 1 and 3. The clay from the ostka 28 of the priest gives into the feeding box 24 and the mold 13. Then with the cam washer 12 the mold 13 is moved to the movable punch 16 and its upper wall 29 covers the volume between the movable punch 16 and the stationary punch 25. At the same time the cutter 30 of the nutrient box 24 closes the chute 28 and stops the mass flow from the chute into the mold. After the mold 13 is filled with clay and closed on all sides, the eccentric 14 is driven B to move the movable punch 16 towards the fixed punch 25. The cam plate 12 in its internal profile has a free gap allowing the form to move freely towards the fixed punch 25 friction of the pressed mass against the walls of the form. This happens because at the beginning of pressing from the side of the movable punch 16, the forces of friction of the pressed mass against the walls of the mold 13 are created. The mold 13 will move freely due to the free gap of 12 friction forces until the friction forces of the compressed mass from the movable punch 16 and from the stationary punch 25 are balanced. Thus, during pressing

Ma 13 without the fate of mechanisms, and only by friction forces, will itself move towards the stationary punch 25, which will ensure correct horizontal two-sided pressing.

After the pressing of the cam lobe 12 is completed, the mold 13 moves further towards the movable punch 16, releasing the pressed brick. At this time, the rim 10 lifts the tenant up, on which, under the action of its weight, a brick lays down, and then the same rim 10 lowers the tenant down along with the brick. The mold 13 by the puck 12 returns to its original position for backfilling and at the same time, with its lower part, the molded brick is pushed onto a circular rotary table 31, from where the brick is removed in the usual way onto a belt conveyor. The movable punch 16, after being pressed, returns to the starting position of the cam tab / 5. During the filling with clay of one of the molds 13 from one heat, all the remaining heat 28 will be blocked by cutters 30. The feed for the press forms does not come directly from the heat, but with the help of a feeding box connected with the drain, which will ensure reliable filling of the molds with the mass.

All chips can be electrically heated in order to avoid mass sticking during pressing.
