Description

The utility model relates to stone processing and may find application in the manufacture of products of complex profile made of stone, intended for architectural and construction works and decorative purposes.

Known machine for rope sawing stone containing at least a movable cutting plate of diamond fragments, mounted for rotation by means of a motor and gearbox, a vertical metal frame of approximately triangular shape, supported by the lower part, at least on a hinged manipulator, one of its ends pivotally connected to the said frame, whereby it can be rotated around a vertical axis in various adjustable positions, with its other end pivotally connected Yen with a vertical column, is additionally equipped with a horizontal support table and has adjusting means for adjusting the frame, a template made with a contour corresponding to the contour of the workpiece, (see IPC B23D 53/00, B23D 55/00, B23D 1/08 description of the invention to the patent No. 2428285, publ. 09/27/2011).

The disadvantages of the known device are the duration of processing and the low quality of the finished product.

Closest to the claimed technical solution is a machine for rope sawing of stone, containing guides on which the driving and driven pulleys are placed with the possibility of reciprocating movement, a cutting body covering the pulleys in the form of an endless diamond-containing rope, a table with a stand for moving the sawed stone, the support mechanism cutting body in the cutting zone, made in the form of longitudinal carriages, mounted with the possibility of a reciprocating movement autonomous from each other horizontal plane, the cooling system of the working body, the CNC system for controlling the processing of the stone contour associated with the drives for moving vertical carriages and rotating the driving pulley (see IPC B28D 1/08, utility model description to the certificate of the Russian Federation No. 7933, publ. 16.10 .1998) - the closest analogue.

The disadvantages of the known device are:

- the complexity of the design, due to the location of the feed table;

- low reliability;

The technical result of the claimed utility model is to improve operational characteristics, including the quality of finished products.

The essence of the technical solution lies in the fact that with a stone cutting machine containing a cutting body made in the form of an endless diamond-containing rope, a cutting body rotation system, a table for placing the processed stone, equipped with a displacement drive, a CNC machine control unit, a rotation system the cutting body comprises a cantilever-type housing on which the driving and driven pulleys, idler and guide rollers are mounted, mounted on the same console with one of the driven pulleys, while the housing is anovlen on a movable platform, a table for placing the treated stone is rotatable with rotatable 360 ° relative to the cutting body is provided with a clamp and a toggle mechanism for pressing the workpiece.

The cantilever-type housing, at the ends of which guides are installed with driving and driven pulleys mounted on them, tension and guide rollers mounted on the same console with one of the driven pulleys ensures its accurate feeding into the cutting zone with achieving the required cutting angle and improving the quality of processing.

The introduction of tension and guide rollers eliminates the possibility of weakening the tension of the cutting body and its sliding from the driving and driven pulleys, providing the necessary reliability of both the cutting body and the machine as a whole.

The installation of the casing on the platform and the execution of the table for placing the processed stone rotatable 360 ° relative to the cutting body allows you to provide the necessary radius and angle of cutting with a reliable clamping of the stone, which significantly affects the quality of the processed stone surfaces.

Supply of a table with a clamp with a knee-lever mechanism provides reliable clamping of the processed stone.

The proposed device is illustrated by drawings, where in FIG. 1 shows a general view of the machine.

The machine for rope sawing of stone contains a cutting body, made in the form of an endless diamond-containing rope 1, its rotation system, comprising a housing 2 with a console 3, on which are placed the leading 4 and driven 5, 6 pulleys, a tension roller 7, a guide roller 8. Case 2 mounted on a movable platform 9, and the table 10 for accommodating the processed stone is equipped with a 360 ° rotation drive 11 and a clamp 12 with a knee-lever mechanism 13 and a clamp 14, which ensure fixing in the desired position of the processed stone 15. The control unit 16 a CNC com is mounted on housing 2.

The machine for rope sawing of stone works as follows: The processed stone 15 is mounted on the table 10 and secured with a clamp 12 equipped with a clamp 14. When the engine 17 is started, rotation through the belt drive 18 is transmitted to the drive pulley 4, which is located on one shaft (in the drawing not shown) with the driven belt pulley 19 of the belt drive 18. The driving pulley 4 drives the driven pulleys 5,6, and with it the endless diamond wire 1. The platform 9, together with the housing 2, makes its reciprocating motion e moves the cutter body perpendicular to the processed stone 15, asking the cutting radius. At the same time, the rotary table 10 rotates the stone 360 ° perpendicular to the cutting body, providing the necessary cutting angle. In this case, the control unit 16 ensures the operation of the machine in polar coordinates to obtain the necessary straight-line cuts. The centering of the clamp during the operation of the machine is provided by a clamp 12 and a clamp 14, which allows to provide the necessary angle and radius of cutting.

Compared with the known devices of a similar purpose, the claimed utility model is simple both in its design and in the method of control and operation, has high reliability during operation and ensures high quality of machined cut stone surfaces.
