Description

The invention relates to the processing of metals by pressure, in particular to devices for cutting steel, can be used in industry for cutting pipes and sections. five

It is known a device for cutting rolled products containing a drive faceplate mounted in a housing, on the inner surface of which a ring gear is made, axles fixed in the faceplate and bearing gears interacting with the ring gear, holders mounted on the axes can be rotated relative to them, cutting tools, located in the holders, connected by means of 15 gears with gears and interacting with fixed cutting tools mounted in the housing, and a node of rotation of the holders in Ideal cam and electromagnet with rod and spring 20

However, the known device is inefficient, difficult.

It is also known a device for cutting rolled products, containing a drive face 25, mounted in a housing, on the inner surface of which a gear rim is made, axles fixed in the face plate and carrying gears interacting with a gear rim, holders with figured 30

cavities mounted on the axes can be rotated relative to them, cutting tools located in the holders [2].

A disadvantage of the known device is its low reliability due to the presence of shock loads.

The purpose of the invention is to increase the reliability of the device.

For this purpose, the device is equipped with a disk fixed on the faceplate and having channels for supplying the working fluid, the shaped holders of the holders have holes that are in the same plane with the outputs of the disk channels.

FIG. 1 shows the device, section A — A of FIG. 2; in fig. 2 - section B — B FIG. one.

The device contains a 'drive faceplate 1, mounted on bearings 2 in the housing 3, on the inner surface of which a gear ring 4 is made.

In the drive faceplate 1 (having the form of a disk shaft) are fixed movably with one end of the axis 5, on the other ends of which the gears 6 are mounted, engaging with the rim 4. The holders 7 in the form of discs are mounted on the axes 5 with the possibility of rotation relative to them. Cutting tools 8 mounted on axles 9 located

in holders 7 and connected with gears 6 by means of gears in the form of gears 10 and 11, with gears 10 fixed on axles 9, and gears 11 on axes 5. The holders' center of gravity is offset relative to the axes and balanced during rotation in such a way that the cutting the tools 8 are in the position indicated in FIG. 2. In the holders 7 there are figured cavities 12 having openings. On the faceplate 1, a disk 13 of light material is strengthened coaxially with it, in which channels 14 are made for supplying the working fluid displaced relative to each other. In the center of the disk 13 a tank 15 is mounted, in the Cylindrical part of which there are two windows that are located opposite the channels 14 in the disk 13 and serve to transfer oil from the tank to the channels 14. The tank is connected to a hydraulic system (not shown) from which under pressure oil is fed through an adjustable valve 16. The holes of the shaped cavities 12 are in the same plane with the outlets of the disk channels.

Cutting tools 8 interact with fixed tools 17 mounted on the housing 3 with the help of clamps 18.

The device works as follows.

From the electric motor 19, the faceplate 1 rotates through the overrunning clutch 20, the gears 6 roll around the crown 4 and the gears 11 rotate through the axles 5, which transmit the rotation to the Gears 10 fixed on Axis 9 with tools 8 fixed in them (fyg. 1 and 2).

The holders 7 are balanced. So that, when rotating the drive plate 1, they rotate synchronously with it and the cutting tools 8 are located closer to the center of the plate 1 (Fig. 2).

For the implementation of the rolling cut, the valve 16 is turned on through the electrical system. Part of the pressurized oil is ejected into the channels 14 through the corresponding windows in the tank 15, and the oil is pushed into the figured cavities 12 of the holders 7 by means of centrifugal forces And pressure.

As a result, the Centers of Mass of the holders 7 move to the zone of the shaped cavities, and under the action of a jet of oil the holders 7 will begin to turn quickly

circle axis, and tools 8 at high speed will enter the cutting zone when interacting with the tools 17, will produce cutting, At the same time portions of oil from the shaped cavities under the action of Centrifugal forces will be thrown into the cutting zone simultaneously with the cutting. Holders 7 iodine The action of changing the center of mass will occupy the original position (fig. 2).

Cutting tools make when turning holders 7 power uDar-imyuls And vortex cutting.

The proposed device can be used for cutting pipes and shaped rolled products, as well as for machining bodies of revolution. The cutting of pipes and sections is carried out with the help of Tool 8 in the form of a thin disk, and the processing of parts of bodies of revolution is carried out with the help of cutters.

When machining rotating bodies, the stationary tool 17 and the clamp 18 are removed, and the workpiece passes through the hole in the housing 3 and is fixed in the centers of the lathe.

The use of the device allows to increase its reliability due to the reduction of shock loads, to reduce the heating of the cutting tool.
