Description

In the proposed device for trimming the edges of the tile, a knife is used, made in the form of a frame bent along a closed line and attached to a paijie pivotally suspended from a turret press frame.

The drawing shows a side view of the device with a partial section.

The fixture consists of a frame b, hingedly suspended from the press frame and bearing the knife g, made in the form of a frame, curved along a closed line, and intended to cut off all the edges of the tile from above. On both sides of the knife 2, planes are provided that serve as guides and are intended to prevent the wounds of the hands of workers. Frame b has a branch c, which is under the action of rollers e mounted on a finger attached to the connecting rod of the press or to the piston g.

In the lower position of the gun, the cutting edge of the knife r is pressed tightly against the surface of the die throughout. When raising the punch, the knife g moves away from the matrix along the arc described from the center O, and at the upper position of the punch, the distance of the knife from the matrix will be greatest.

During periods of drum rotation on its axis with a pentagonal tile of 72 °, the knife is separated from the matrix at the maximum or close to such a distance, and thus both the bottom of the cut tile and the approach to the knife of the new pressed tile occurs unhindered.

After the knife is lowered onto the matrix, the worker lays the lining on the horn delineated by the knife, and after the drum rotates it takes the tile to the same lining to be sent for drying.

In case the dimensions of the punches will be so wide in width that the smooth movement of the knife g will be difficult, the branch should be made in a less curved and spring-loaded mode; then, when moving down, the knife i will advance the puncheson, and when moving Biepx, it will lag.

The subject matter of the invention.

A device for trimming the edges of a tile that is molded on turret presses, characterized in that a knife cutting from above all edges, made in the form of a frame I bent along a closed line, is attached to the frame 6, hinged to a press frame and having a branch in which is under the action rollers d, put on a finger, attached properly either to the connecting rod or the press, or to the gun.
