Description

The invention relates to a device for cutting materials used in the construction industry, namely to manual cutting tools used for cutting materials, in particular ceramic tiles, slag and metal tiles, tiles, glass and other fragile materials.

A device for cutting sheet brittle material is known, which comprises a flat body on which two springy platforms are mounted, between which in the middle part the support edge is placed on the length of the tile along the longitudinal axis, and the brackets are mounted on it with its center above the edge two guides, the plane of the middle of which is aligned with the median plane of the vertical part of the support rib, along which the carriage consisting of a lever with a stop roller moves, a support roller tiam, roller cutter, stop and return spring, where the guides are made in the form of cylindrical or rectangular rods and equipped with an adjustable stop and measuring ruler, including swivel [1].

The disadvantage of this device is the use of two guides, the need to adjust the device to the desired range of processed tiles.

Another device is known, the model δ tile cutter. Содержащий, comprising a case on which two spring-loaded platforms are placed, between them in the middle part of the case the support edge is placed for the length of the processed tile along the longitudinal axis, above which brackets are mounted with their middle, on the upper part of which is fixed one rectangular guide, the middle plane of which is aligned with the middle plane of the vertical part of the support rib, along which the cutting carriage moves, consisting actually of the housing, which contains nine bearings, a roller cutter, breaking the stop S, connected by a lever and a return spring [2].

The disadvantage of this device is that ensuring the straightness of movement of the cutting carriage is achieved through the use of a large number of bearings rolling on all four straight planes of the guide, and as it wears out, the play can not be eliminated and restoration of the tile cutter can only be achieved by replacing the guide. Breaking stops in their horizontal part are not long enough, as a result of which chips are observed on the tile after its breaking.

Also known is the design of the device KaiEtai, which is the closest prototype, containing a rectangular guide, a housing with spring platforms placed on it, between which on the case in its middle part there is one rectangular guide, the plane of the middle of which is aligned with the middle plane of the supporting rib along which the cutting carriage consisting of the body itself, in which the rolling bearings are placed along the straight planes of the guide under and on it, the roller cutter, breaking it pores connected by a lever, breaking stops, a return spring and an adjustment mechanism for adjusting the device to a given tile thickness [3].

The disadvantage of this device is that ensuring the straightness of the movement of the cutting carriage is achieved through the use of bearings rolling in straight planes of the guide, and as it wears out, the play cannot be eliminated, where the restoration of the tile cutter can only be achieved by replacing different thickness of tiles, and breaking stops structurally imperfect in their horizontal part, not long enough, resulting in chipping on the tile after its fracture.

The objective of the invention is to eliminate the above disadvantages and create a manual cutting device for cutting materials, including fragile ones.

The essence of the proposed device for cutting materials consists of a body 1 with two spring-loaded platforms 12 placed on it, in the middle part of it a fixed supporting edge 2 fixed on two racks 4 placed at the ends of the body 1, a profiled guide 4, the middle plane of which coincides with the middle the plane of the support rib 2, on which is placed the cutting carriage 5, containing three rollers 8, each with two bearings, with a return profile guide, two under and one on the guide 4, midway between them peeking with their profiles on the profile of the guide and rolling along it, where in the carriage 5 on the supports along its sides there are breaking elongated two-step legs 7, between which the cutting roller 6 is placed, and in the upper part of the carriage 5 on the axis there is a handle 10 with a manual 11, which in turn, two rods 9 are connected to tabs 7, where the design of the tabs 7 with the roller knife 6 placed on them allows the tile to be cut in the selected range without adjustment, and the design of the profile of the guide 4 and rollers 8 automatically centers the re taper roller 6 in the median plane of the support rib 2 and to reduce the breaking force of tile 19 after it has been cut, as well as eliminating chipping, the size of the breaking part of legs 7, wings 18 are enlarged, and their design is almost parallel to tile 19 lying on platforms 12 over the entire stroke length when breaking and falls almost vertically on the entire length of the course.

The technical result of the invention is to create a device that allows you to simplify its design, technology for cutting materials, including fragile ones, as well as to increase reliability and maintainability during its operation.

The invention is illustrated by drawings:

- 1 019409 FIG. 1 - a general view of the device in the frontal image, the carriage at the beginning of the tile cut; FIG. 2 - a general view of the device with a ruler with its stops with the cutting carriage removed; FIG. 3 is a top view of the device with a measuring scale with its stops with the cutting carriage removed; FIG. 4 - section BB-device on the body and platforms;

FIG. 5 - view A of the device;

FIG. 6 - view from the device;

FIG. 7 and 8 - carriage with a roller, a cutting roller with legs with wings and their design.

The device consists of a flat body 1 with two platforms 12 placed on it on springs 13, in the middle part of the body a supporting edge 2 is fixed on racks 3 installed along the ends of the body, a profiled guide 4 is fixed so that its middle vertical plane coincides with the middle vertical plane support rib 2, on it is placed the carriage 5, on which three rollers 8 are installed, each on at least two bearings, two under and one on the guide, midway between them, having a response profile eg The adapter and the profile of the guide that they support and roll along it when the carriage 5 moves, where in it, on the supports, are placed on the sides, breaking elongated two-step legs 7, between which the cutting roller 6 is placed, in the upper part of the carriage 5 on the axis there is a handle 10 sec. handle 11, which, in turn, is connected by two rods 9 to tabs 7, whose construction with the roller knife 6 on the bottom allows the incision of the tile 19 in the selected range without adjustment, where the design of the profile of the guide 4 and the rollers 8 is automatic ski centering the cutting roller 6 in the median plane of the support rib 2, and to reduce the breaking force of the tile 19 after it has been cut, and also to exclude chipping, the size of the breaking part of the legs 7, wings 18, is increased, and their design is almost parallel to the platform throughout the entire stroke length at breaking tiles 19 laid on them. In this case, the wing 18 of the presser foot 7 goes down almost vertically along the entire length of the stroke.

The device works as follows.

Remove the cutting carriage 5 to its original position (Fig. 1).

The tile 19 is laid with the glazed surface upwards with the selected front end up to the fixed stops 15 and to the specified cut size on the spring-loaded platforms 12. For which, tile 19 is set along the cutting width either by eye or by means of the gauge 16 as needed. Lowering the handle 10, adjust the roller The knife 6, until it touches the tile 19 from the rear end, presses the handle 10 and deepens it 1-2 mm into the body of the tile and, moving the carriage 5 forward, makes an incision of the tile 19 to its front end. In this case, the lower rollers 8 are pressed against the beveled surfaces of the guide 4 without backlash. Finishing the incision of the tile, they transfer the roller knife 6 to its redistribution, for the fixed support 15 so that the tabs 7 are 10-12 mm from the end of the tile.

Now, lowering the pads 7 with the help of the handle 10 down onto the tile 19, it is broken by the wings 18 of the paws 7 into two parts on the supporting edge 2. In this case, the platforms 12 with the broken parts of the tile 19 under the action of the paws 7 fall to the stop against the body 1 As a result, tile 19 is divided into two parts.
