Abstract

The invention relates to the cutting of natural stone and other building materials and improves the productivity and durability of a diamond cutting tool. This is achieved by the fact that the protective casing is equipped with an inner shell and end walls 8 and 9, on which, thanks to flanging, radial slots are formed, evenly spaced around the periphery and the ends. Fine particles of degradation products pass through exhaust channels. The protective cover is made with double walls. 4 il.

Description

The invention relates to the cutting of natural stone and other building materials and can be used in the manufacture of building products

The purpose of the invention is to increase the productivity and durability of diamond tools.

Shown is a device for cutting natural stone; Fig, 2 is a longitudinal section of the casing of the device; on figoZ - section aa on fig „2; in Fig o 4 - view B on figoZ,

The device consists of a diamond cutting disc 1 with diamond-bearing elements 2, along the periphery of which there are nozzles 3 and 4 receiving coolant from source 5 “Above the diamond cutting wheel 1 a protective cover 6 is installed, equipped with an inner shell 7 and two inner end walls 8 and 9 respectively o The inner shells 7 and the end walls 8 and 9 are equipped with slots 10 and 11, respectively, which are formed by petals 12 and 13, which are directed in the opposite direction to the rotation at an angle c / o. To prevent The ground part of the casing 6 is equipped with a 14 ° pallet. The destruction products falling into the cavity 16 of the casing 6, located between the outer and inner walls of the casing 6, are carried out simultaneously via two channels 17 and 18, in two diametrically opposite sides of the tool cient, which takes the band (

The device works as follows

From the source 5, the coolant is fed to the periphery and end surfaces of the rotating diamond cutting wheel 10 by means of nozzles 3 and 4. respectively along the periphery of the inner shell

7i on the front inner walls

8 and 9, the diamond-bearing elements 2 are cooled rapidly under the action of the coolant, as a result of which the bond of the diamond grains of the diamond-bearing elements 2 does not have time to soften and thus creates an opportunity to increase the strength of diamond backing and reduce the consumption of diamonds

Fine particles of degradation products are entrained by the rotating cutting wheel 1, passing under the screenings 12 and 13, set at a distance from the cutting wheel on the inner side of the walls 8 and 9 and the shell 7 in the direction opposite to the rotation of the cutting wheel. their back sides cause turbulences of the flow of fine particles of destruction products, as a result of which the flow of fine particles of destruction products rotating along with the cutting wheel 1 is interrupted, and they pass through the radial The second slots 10 and 11, fall into the cavity 16 of the casing 6 Next

products of destruction are removed from the cutting zone through exhaust channels J 7 and 18, and are recycled. In order to reduce dust formation, sprayed water is supplied to the zone of exhaust channels 17 and 18 using nozzles 19 and 20. The front part of the casing 6 is equipped with a tray 14, which prevents the penetration of degradation products into the cutting zone in the event of an accidental shutdown or malfunction of the aspiration system. The presence of a cutout 15 along the periphery of the inner shell 7 facilitates the smooth removal of cutting products ejected into the kerf in the form of a flare
