Description

Revolver press with double pressing for the production of interlocking tiles. In the production of interlocking tiles in press molds is cleaner for the achievement and even contour pressing as well as twice to prevent blistering Pressing the brick is an advantage.

With the turret presses, which can be rotated about a horizontal axis, you have a double pressing of the brick accomplished in such a way that one by means of an eccentric pressing twice on the same upper form twice in a row lets the brick, which remains in the same position, go down.

However, this way of working requires a slower operation and thus reduced performance of the press as well as too rapid wear of the upper mold.

The subject of the invention is the double pressing of interlocking tiles with turret presses by means of two simultaneously moving upper molds, of which the one is pre-pressing the brick, while at the same time the other is pre-pressing one After-pressing brick, so that pre- and post-pressing here in the same operation take place. Since with the revolver press the different work surfaces are not in the same Lie level and accordingly the two upper forms not in parallel direction are to be moved, so here is the one upper form of a movable one Machine part made by suitable means of movement transmission at an angle to the direction of movement of the main ram so that it is perpendicular to a second work surface the revolver drum goes up and down.

For example, the movement of the bearing the second upper mold Press ram by a second one upstream from the main pressure wave Pressure wave done by means of tie rods and guide levers.

Pre- and post-pressing can basically be done on any work surface the drum take place. Usually, however, the repressing is carried out by the Main press ram moved in the vertical direction when the brick is in the horizontal position Direction is located, and the pre-compression with a previous inclination of the Brick.

The pre-pressing can, for example, be based on the horizontal position of the Die immediately upstream of the working surface of the revolver drum, ie on the on the upper side, but it is more advantageous to pre-press on the lower side Side of the revolver drum. This has the advantage that during the pre-pressing the excess clay mass, the so-called press burr, does not fall on the pressed part and can damage it, which is known as a a great evil was felt.

The small amount of clay that was still used as a press burr during re-pressing emerges, is expediently in a known manner by a Burr cutter separated from the brick.

In the drawings is an embodiment of the subject of the invention shown, namely in: Fig. i in side view (drum locking side) partially in vertical cross section, in Fig. @i partially in side view, with the ram are in the pressing position, in Fig. 3 in side view and cross-section accordingly Fig. Z, with the ram in the rest position, in Fig. Q. in Rear view, in Fig. 5 in side view (drive side) and in Fig. 6 in front view (Burr cutter side).

The roof tile revolver press has in addition to the usual press ram a above the revolver drum a second ram b below the same, which wedged onto a shaft c by two levers d, dl attached to the latter on an the uprights of the press attached bolts e, e1 is rotatably mounted.

The columns of the press are according to the stroke size of the second Press ram equipped with cutouts f, f1.

The main pressure wave g drives a second pressure wave i through gears h, hl, at the ends of which cranks k, hl are attached, which are connected to the shaft c by tie rods 1, 1l.

After the turret press has been put into operation, in addition to the pressure ram a, the second press ram b also leads by simultaneous rotation of the second pressure shaft i. by means of the cranks k, k1 and tie rods 1, h and is removed from the compact in the same way after the pre-compression is complete and brought into the position shown in Fig. 3, which enables the clay cake to be conveniently placed on the pre-compression die.

To prevent the brick from falling or being pulled off after the pre-pressing has been completed To prevent the lower revolver drum shape, it is still advisable to use the iron edge to keep the lower mold wide so that the press burr with the brick adheres to it, while conversely the iron edge of the stamp form must be narrow.

Claims (1)

PATENT CLAIMS: i. Revolving presses with double pressing for the production of interlocking tiles, characterized in that in mechanical connection and at the same time with the main press ram (a), namely at an angle to this, a second press ram (b) is pressed perpendicularly onto the corresponding working surface of the drum and pre-presses a brick, while at the same time the main ram represses the brick that was prepressed in the previous operation. z. Revolving press according to claim i, characterized in that the bricks are pre-pressed on a work surface on the lower side of the revolving drum.
