The invention relates to woodworking disk tools and can be used in woodworking industry when sawing wood and wood materials,

The purpose of the invention is to improve the accuracy of cutting, reducing energy consumption and noise level of the disk tool.

FIG. 1 shows a disk tool, a general view; in fig. 2 is a section A-A in FIG. in fig. 3 is a section b-B in FIG. one; FIG. 4 shows the principal cutting scheme of wood material; in fig. 5 shows a bellows chamber device for creating pressure of a ferromagnetic fluid.

The disk tool consists of Ko-guides of guides 1 and 2, on which 3 magnetic conductors 3 and 4 are fastened with the help of pressed-in pins 5 and 6 with thread and nuts 7 and 8 in the body of guides 1 and 2. In magnetic conductors 3 and 4 A non-magnetic material is pressed in 9 (10), in which pole-mounted pole 11 is pressed in. The non-magnetic material 9 (10) is separated from the magnetic cores 3 and 4 by spacers 12 and 13 made of a non-magnetic material. Non-magnetic Material 9 (10) is made with an internal closed cavity 14 (15),

which is filled with ferromagnetic fluid through flexible pipes 16 and 17. Rows of holes 18 are made in non-magnetic material 9 (10). A disk tool 19 is installed between the planes of non-magnetic material 9 (10) with a gap of not more than 0.1 mm using a gasket 20 and fastening screws 21. The ferromagnetic fluid pressure in cavities 14 and 15 is created by a bellows chamber 22, a spring-loaded spring system 23, which is clamped by an eccentric 24. A valve 25 is installed at the outlet of the chamber 22. The chamber 22 is provided with an opening 26 for supplying liquid, the latter Closing the cap 27. The guide housing 1 is secured to the machine frame 28 and the housing guide 2 fixed to the screw body 21. Similarly, secured to the frame second part of said tool. The processed material 29 is fed through the base 28 to the tool 19. The plane of the non-magnetic material 9 (10) facing the tool 19 protrudes with respect to the magnetic cores 3 and 4 and the ferromagnetic pole. 11 to 0.1 mm. Disk tool 19 is installed on the spindle 30-.

Disk tool works as follows.

Magneto conductors 3 and 4 together with the pole cells 11 and the tool 19 form closed magnetic fluxes, the gaps of which retain and hold the ferromagnetic fluid, which is under pressure in the cavities 14 and 15. The ferromagnetic fluid is retained in the gaps due to the intensity of the magnetic field (when the polar points are made of KS-37 material, the fluid retains liquid at a pressure of up to 30 kg / cm). The magnetic conductors 3 and 4 and the pole members 11 play the role of magnetic-fluid seals. The pressure of the ferromagnetic fluid in cavity 14 (15) is created by the compression of the bellows chamber 22 by a system of 23 springs and an eccentric 24. This

the same pressure is constantly provided by che-2o. A layer of liquid plays the role of a spring, cutting 18 holes through the liquid lubrication of the tool 19 during rotation. To replace the tool 19, the action of the spring system 23 on the bellows chamber 22 by the eccentric 24 is weakened. In this case, the tension springs of the elastic system 23 operate and the ferromagnetic fluid from the cavities 14 and 15 is sucked into the bellows chamber 22, after which the valve 25 is closed. 2 together with the magnetic conductors 3 and 4, the non-magnetic material 10 and the pole members 11 are removed from the casing by screwing in screws 21. A similar operation is performed in the lower part. After that, the tool 19 is removed from the machine spindle.

The installation of the disk tool 19 is performed in the reverse sequence of operations: mounting the case and fixing it with screws 21, setting the gap between the tool 19 and the nonmagnetic material 9 (10) using a gasket 20, Then the valve 25 is opened and the spring 23 is pressed by the eccentric 24.

This device allows the use of a thin disk tool, the thickness of which can only be limited by the strength of the carbide alloy attached to the front face of the tooth, regardless of the diameter of the tool. The operability of the proposed disk tool is ensured by the direction of its rotation through a sliding bearing with hydrodynamic lubrication. The forced pressure of a ferromagnetic fluid damps the transverse trackline of the disk.
