RU2304510C1 - Device for cutting tile - Google Patents

Abstract

FIELD: working stones or stone-like materials.

SUBSTANCE: device comprises base, tubular guides mounted on the base, carriage provided with rocking axle and set in the tubular guides for permitting longitudinal motion, rocker pivotally connected with the rocking axle and made of a double-arm lever whose one end is provided with the cutter and the other end is provided with breaking member made of lugs, and control handle connected with the rocker. The rocker has stops for arresting rotation of the control handle.

EFFECT: enhanced reliability and expanded functional 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 the other and the control handle connected to the beam, the latter is pivotally connected to the beam and mounted on the swing axis, and stops are made on the beam to limit the rotation of the control handle and for I am interacting with the latter.

Figure 1 shows the proposed tile cutter, General view,

figure 2 is a view along a in figure 1,

figure 3 - rocker without a cutter, General view,

figure 4 is a view along B in figure 3,

figure 5 - section bb in figure 4.

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 legs on the other and connected to the rocker 6 control handle 9.

The control knob 9 is pivotally connected to the beam 6 and mounted on the swing axis 5, while the stops 10 are made on the beam 6 to limit the rotation of the control handle 9 and to interact with the latter.

On the working base 1 there is an elastic substrate 11 and a measuring ruler 12, 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 (figure 5).

Tile cutter works as follows.

The control handle 9 from the rightmost position (FIG. 1 and FIG. 2) is turned to the extreme left position, while it rests against the left (in FIG. 2) emphasis 10. The carriage 4 of the control handle 9 is also moved to the extreme left position. Ceramic tile (not shown in the drawings), which must be cut, is placed on the elastic substrate 11 of the working base 1 close to the measuring ruler 12. 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, a breaking unit 8 is installed at the specified location of the tile, the control knob 9 is turned clockwise to the extreme right (as shown in FIG. 2) position to the stop 10 and the handle 9 pushes this emphasis 10. The breaking unit 8 acts on the tile and splits it exactly along the notch line. This design of the tile cutter allows you to divide the tile into parts, placing it on the working base 1, without abutting the measuring ruler 12, and also to exert pressure on the tile at any point, thereby ensuring its reliable separation into parts, including along a broken line.
