Description

This invention relates to devices for two-sided pressing of tiles, etc. products in which the walls of the forms are movable.

Distinctive features

The proposed device is that in order to keep the table in a non-iodine / 15th time condition, it is filled with and prefixed with a stamp of a press in it used latches (paws) installed on the frame and interacting with the form, as well as rods, entered with an emleplem and a foreigner to turn off the hooks in order to release the walls of the mold after 11 contractions of the mass.

depicts a device for pressing tile spike; Figures 10, 11 and 12 show a device for punching a hole in a spike of a tile; Figures 13, 14 and 15 show a device for ejecting a finished product from a mold.

The so-called "wet method of making roofing tiles, which encompasses its long-lasting drying after pressing, is extremely labor-intensive and expensive. At the same time, the tile often has a curvature in different directions, and often cracks, resulting from the drying of freshly formed raw tile.

Without pre-drying, the stem cannot be, "See your own; 5Pcs, removed from the shelves and sent to the next and final operation of the production process - roasting.

It is more profitable to produce it according to the so-called "semi-dry 1P1H1" method, in which the raw tile is not pressed from clay dough; and from clay powder with lower humidity, thanks to the whole production cycle

should be significantly reduced and cheaper, since the most time-consuming and complex operation is drying completely disappears. The raw shingles pressed in this way can be sent directly after pressing directly into the kiln.

The proposed device for the manufacture of clay folded tiles in a dry or semi-dry method provides for bilateral pressing of tiles or similar products, which contributes to obtaining products equally dense with Toff and on the other hand.

The device can be installed on punching presses of any system that have sufficient pressing force and stop after a cycle of press release to remove compressed tiles from a stamp.

The device has implemented a method of two-sided pressing of a mass (powder) in the form with one movable stamp and with the stationary friend, with the form of the press freed from any direct connection with both stamps (i.e. the form has the ability to move freely the direction of movement of the pressing stamp). When v {), opMa will change its position relative to that of another stamp in accordance with the gradually changing compressive mass, shifting due to the friction of the compressible mass (clay powder) in the direction in which the mass is less compacted, t. e. towards the immovable stamp. The displacement of the freely movable form will all the time automatically adjust the compaction of the mass of the one and the other stamp to the same size, that is, from two sides.

Such a device provides for the regulation of the amount of filling the form.

in it, the masses during pressing, forlta, having two guide sleeves 2. do not drop to the press frame, but slide along two parallel rods 3 fixed on the press frame. The rod 3 is fixed with a cut end in the base plate 4. The sleeve 2 is attached to the form / flange with two bolts. Outside, the sleeve 2, but the entire length, has a cutting 5. A cutting sleeve 6 is attached to the cutting, which serves to control the amount of filling the form and has a circular protrusion / for locking the pawl 8 / and for fixing the sleeve 6 fixedly on the thread of the sleeve 2 a locknut 9.

FIG. 3-5 shows the course of double-sided pressing of a tile with a fixed lower stamp and a free form during the compression of the mass in it.

In addition to the above features, FIG. 3 - 8 specified || the following details of the mechanism; 10 - plate spring pressing the dog S; 11 - roller sleeve, sitting on the same axis with the dog 8; 12 - bearings axis doggie 6 (Fig. 6); 13 - n / a current, attached to the upper cross of the press n, therefore, moving along with it and the upper stamp; 14 - bottom fixed stamp; 15 - top stamp, inserted on the upper beam of the press; 16 — fixed support fixed to the base plate of the mechanism; 17-clay poronyuk loaded into the form.

FIG. 3 shows the arrangement of the parts at the time of the beginning of the compression of the clay poron in the form, viz.

The form / is supported in the upper position by the dog 8 resting on the protrusion 7 of the sleeve. 6 The sleeve 6 is locked by the nut 9 to the sleeve 2. At the same time, the form is tightly pressed against the fixed stop 16. The lower stamp 14 lies tightly on the stops transmitting press bed pressure. The Upper stamp of the J5 approached tightly to the powdered / clay powder 17.

Figure 4 shows the same mechanism action, but the upper stamp J5 entered some distance into the form / and squeezed the clay powder J7, and the stem 13, D1; going down along with the upper stamp /) 5, went to the roller JJ sitting on one axis with a dog 8.

Figure 5 shows the last period of compression of the clay powder in the mold, when two-sided pressing is performed with one upper movable stamp J5 to the free form. Upon further downward movement, as compared to the position shown in FIG. 4, the top of the stamp 15, the rod / J, pressing on the roller // will squeeze the pawl 8 from under the protrusion 7 of the sleeve 6, as a result of which the shape / will be held "by weight by friction on its wall, the mass 17 pressed in it at this time the lower stamp is stationary 14. As soon as such a situation has been created, and stamp 15 continues to press on mass 17 and the latter will be further compressed to a certain limit, the form / will begin to shift along with the mass compressed in it / 7, towards the stationary stamp , and its shift towards the lower P1te Pel 14 will go up to that time and at such a value that is required for the same compaction of the mass in the form of the upper / 5 and the viable stamp. And, as is experience, the magnitude of the form shift towards the stationary stamp 14 is approximately equal to half of the magnitude of the upper stamp. 15 during the time from the moment of release of the form by the dog 8 until the moment of final compression of the mass in the form. Figure 5 shows the downward displacement of the shape relative to the fixed support 16, between which and the shape / a gap is formed.

stamp, and then the bottom. The latter, lifting to the level of the upper edges of the form 1, pushes the pressed powder out of the form already in the form of raw tile and at the same time, thanks to the friction of the squeezed tile against the wall of the form, lifts the latter up to the stop / 5.

As soon as the shape / contact of the anvil 16, the pawl 8 will drop over the protrusion 7 and the shape / will be in the preparedness position for the next loading with clay powder.

The knot of the mechanism for pressing the spike of the tile (Fig. 9) consists of the following main parts: 18- bronze bushing fixed in the lower mTeMnevie, in which the spike of the tile is pressed; 19 - the upper part of the stem which fits tightly into the sleeve 18, and the lower part into the guide sleeve 20; 19 - the same stock in the extreme upper position (dotted line); 2 / - yoke in the down position; 2 / - the same beam in the upper m position (dotted line); 22 - supporting roller; 23 - support bracket; 24- a roller freely rotating on an axis fixed in the body of the rocker 2 /; 25 - pusher fixed in the upper beam of the press.

The spike is pressed simultaneously with the compression of the mass (clay powder) in the form (when the upper stamp moves / 5 from the position shown in the drawing by solid lines to the position indicated by a dotted line inside the form). When the upper stamp / 5 is in the extreme upper position, then the pusher 25 is in the same upper position (shown by dotted line 25), since both the stamp / 5 and the pusher 25 are fixed on the upper beam of the press. By lowering the top stamp / 5 to the upper edges of the form /, the pusher 25 goes to roller 24. With further deepening of the stamp / 5 into the form / under the influence of a gel 25, the roller 24 goes down and together with it the tile lies tightly on the stamp //.

As soon as the stamp // is supported to the level of the upper edges of the form /, the large arms of the levers 32 will be pressed into the lower surface of the form / n during the further movement of the stamp. / V up the small shoulders of the levers 32 will begin to press on the heads of the pushers 35, compress the springs 36 and separate the plate 33, and with it the tile 34 from the stamp 14. Since the stamp J4 in its final position goes out of shape / 3-5 mm, and the ratio of the arms of the levers 32 is 2/5, the platform 33, with J4 lying on top of it, is separated from P1temnell / - by a gap of 1-2 mm (indicated on the drawing nH (j) poii V7).

A general view of ycTpoiicTBa for two-sided pressing of folded clay tiles and other flat relief products using the semi-dry method is shown in f1P 1 and 2. Figure 1 shows an exemplary installation of the device on the frame of a shaving eccentric compression press. In order not to obscure the mechanism itself in FIG. 2 upper beam 38 of the press is not shown. Also in FIG. 1 does not show the knot, press-1 studs shown in FIG. ten.
