RU2308371C1 - Tile-cutting device - Google Patents

Abstract

FIELD: construction, particularly finishing works, namely working stone or stone-like materials, for example cutting of frangible sheet materials, namely ceramic or slag glass-ceramic tiles.

SUBSTANCE: tile-cutting device comprises working base, tubular guiding means connected to working base by means of posts, slider with rolling axis installed on tubular guiding means so that the slider may perform movement in longitudinal direction and rocking beam pivotally connected to slider. The rocking beam is made as double-arm lever provided with cutter on the first free end thereof and with tongue-shaped breaking unit connected to the second lever end. Control arm is pivotally connected to rolling axis and rocking beam. The control arm is spring-loaded against rocking beam in circumferential direction and may urge breaking unit towards working base. The rocking beam is provided with stops to cooperate with control arm and to transmit force therefrom to cutter or breaking unit.

EFFECT: increased reliability and operational capabilities.

Description

The invention relates to the construction industry, in particular to finishing work, in particular to the design of devices for cutting brittle sheet materials, such as ceramic and slag-ceramic tiles.

The closest in technical essence to the proposed tile cutter is a tile cutter selected as a prototype, containing a working base, guides mounted on it, mounted on the latter with the possibility of longitudinal movement of the carriage with a swing axis, pivotally mounted on the last beam in the form of a two-shouldered lever with a cutter on one of it the free end and the breaking knot on the other and the control handle connected to the beam. The design of the tile cutter allows you to make an incision of the tile on your own, and pressing and breaking it only at the edge (UK Patent No. 2261188, CL B28D 1/22, publ. 1993).

The disadvantage of the prototype is the unreliability of dividing tiles into parts and the impossibility of dividing it, for example, along a broken line because of the need to bring the cutter to the end of the tile and the inability to break the tile in a given place, for example in the center of the tile, because the cutter in this case rests on the tile, interferes with its breakdown, and may also fail.

The technical result achieved by the present invention is to increase reliability by eliminating damage to the cutter during fracture, as well as to increase operational capabilities by expanding the range obtained when dividing the configurations of the parts of the tiles while increasing the reliability of dividing the tiles into parts due to the uniformity of the break by the possibility of pressure anywhere in the tile, including in its center.

This result is achieved in that in a tile cutter containing a working base, guides mounted on it, mounted on the latter with the possibility of longitudinal movement of the carriage with a swing axis, pivotally mounted on the last beam in the form of a two-shouldered lever with a cutter on one of its free end and a breaking unit on another and a control handle connected to the beam, the latter is pivotally mounted on the swing axis and pivotally connected to the beam, the latter is spring-loaded relative to the control handle in the circumferential systematic way to enable pressing the breaking unit in the direction of the working base, wherein abutments on the yoke are made to communicate with the control stick and transfer of efforts from it to the tool or scrap node.

in Fig.6 is a view along D in Fig.5,

Fig.7 is a section DD in Fig.6.

The tile cutter contains a working base 1, tubular guides 3 mounted on it by means of racks 2, mounted on the latter with the possibility of longitudinal movement of the carriage 4 with the swing axis 5, pivotally mounted on the last beam 6 in the form of a two shoulders lever with a cutter 7 at one of its free ends and breaking node 8 in the form of paws on the other and connected to the rocker 6 control handle 9.

The control handle 9 is pivotally connected to the beam 6 and pivotally mounted on the swing axis 5, while the beam 6 is spring loaded with an elastic element 10 relative to the control handle 9 in the circumferential direction with the possibility of pressing the breaking unit 8 towards the working base 1. In addition, the beam 6 stops 11 for interacting with the control handle 9 and transferring forces from it to the cutter 7 or breaking unit 8.

On the working base 1 there is an elastic substrate 12 and a measuring ruler 13, which performs an additional role of a tile displacement limiter. Cutter 7 is made in the form of a roller. The shoulders of the two shoulders of the lever (rocker 6) are located at an angle α to each other, which can be selected in the range from 50 to 170 degrees (Fig.7).

Tile cutter works as follows.

The control handle 9 from the rightmost position (Fig. 1 and Fig. 2) is turned to the leftmost position, while it rests against the left (in Fig. 2) emphasis 11. The carriage 4 of the control handle 9 is also moved to the leftmost position. Ceramic tile (not shown in the drawings), which must be cut, is placed on the elastic substrate 12 of the working base 1 close to the measuring line 13. Next, pressing the control handle 9 towards the working base 1 and simultaneously moving it together with the rocker 6 away from you, those. to the right (in figure 2), the cutter 7, interacting with the surface of the tile, puts on the last risk, giving a weakening of the tile body along the desired line. In order to divide the tiles into parts, the carriage 4 is moved along the guides 3, the breaking unit 8 is installed at the specified location of the tile, the control knob 9 is turned clockwise to the rightmost position, as shown in Fig. 2, to the stop 11 and press the handle 9 on this emphasis 11. The breaking unit 8 acts on the tile and splits it exactly along the notch line. At the same time, the elastic element 10 in the position of the handle 9, in which the tiles are separated (i.e., in the rightmost position, as shown in FIG. 2, position), which allows the positioning of the legs of the breaking unit 8 to be accurately clamped, is provided that the rocker arm 6 is constantly pressed to the handle 9 at a given tile location. This design of the tile cutter allows you to divide the tile into parts, placing it on the working base 1 without resting on the measuring line 13, and also to press on the tile at any point, thereby ensuring its reliable separation into parts, including along a broken line.
