Can be used when cutting glass and ceramic objects.

The purpose of the invention is to ensure the safety of working conditions and improve the quality of cutting.

In fig.) Shows the proposed glass cutter; figure 2 - view A on ig.1.

The glass cutter contains left I and two impellers rigidly planted on axis 3, which rests on bearings 4 and is connected by means of the latter with handle 5. On axis 3 between impellers 1 and 2 there is a cutting disk 6. Inside handle 5 there is an air channel 7 The filter 10 is located in front of the fan 8, which cuts the air in the protective casing 9. In the walls of the protective casing 9 there is a system of nozzles 11, which are conical holes through which atmospheric air enters the blades of the turbine 1 and 2, the drive is simultaneously together with them in the rotation of the cutting disc 6.

The reciprocating movement of the casing 9 is provided along the axis of the tool by the spring 12. The supporting element of the glass cutter is the fluoroplast ring 13.

The device works as follows.

The glass cutter is installed perpendicularly to the plane of the product, the fluoroplastic ring 13 and the light of the casing 9 are made up of a system of nozzles 11 for supplying atmospheric air to the blades of the impellers 1 and 2. The backward movement of the protective casing 9 along the tool axis is provided by a spring 12. Fluoroplastic Cold 13, The design of the device ensures the safety of the operator’s working conditions, significantly improves the quality of cutting, is easy to manufacture, 1 з, п, ф-лы, 2 Il.

pressing the handle 5 brings the edge of the cutting disk 6 at the expense of the spring 12 to the place of the cut. Using the fan 8 in the working area of the protective casing

9 a vacuum is created. Atmospheric air through the nozzle system 11 is accelerated and supplied to the blades of the impellers 1 and 2, driving them to rotate simultaneously with the cutting disk 6, which, moving through the product, breaks the glass to the desired depth and width. The exhaust air with the help of the fan 8 picks up the abrasive dust and carries it to the filter

10. The cutting disc 6 is cooled by atmospheric air flowing through the nozzle system 1 1. At the end of the cutting spring 2 returns the protective cover 9 in

initial position.

Claims (2)

1. Glass cutter containing handle with through channel, protective cover, cutting disc, mounted on the same axis with two impellers and supporting elements, characterized in that, in order to ensure safe working conditions and improve the cutting quality, it is equipped with a fan connected to the through channel of the handle and filter mounted into the latter, the protective casing is made with conical nozzles aimed at the blades of the turbine blades, and the supporting element is in the de kol da of thermoplastic material. 2. The glass cutter according to claim 1, about tl and - due to the fact that the supporting element is made of fluoroplastic. View And
