The invention relates to a cleaning technique and can be used for surface treatment to remove burrs, rust, scale and other contaminants.

The purpose of the invention is to improve the quality of cleaning.

FIG. 1 shows a brush, a general view with a slit; in fig. 2 - the same, top view.

The end brush contains holders 2 wire bundles 3 of pile, having the same length, and placed along two concentric circles. The holders 2 are arranged in such a way that the level of placement of the cutting edges 4 of the tufts 3 of the pile decreases from the center to the periphery.

The holders 2 on the inner circumference are connected to the housing 1, for example, by welding, and on the outer circumference are installed in threaded guide grooves 5 with the possibility of reciprocating movement in a direction parallel to the axis of the brush, and provided with retainers, for example, in the form of a nut 6, having 7 turnkey holes. Each holder 2 bundles of pile 3 has a base 8, in which the bundle 3 of pile, clamped in the collet clamp 9, made in one piece with the glass 10, in contact with the nut 11, having a hole 12 iod key, wedged with a conical pin 13, dispensed one piece with the bolt 14 and the nut 15 mounted with the possibility of axial movement and fixation. The housing 1 is connected to the drive shaft 16.

The nut 11 produces an axial movement of the sleeve 10 and a clamp of the beam 3 installed in the collet clamps 9. The wedging of the beam 3 is performed by rotating the bolt 14, the position of which is fixed by the nut 15.

The brush works as follows.

By rotating the base 8 on the outer circumference, the difference in distance from the housing 1 to the cutting edges 4 of the nap bundles 3 located on the inner and outer circumferences equal to the magnitude of the tension is set. The feed rate

and the pressing force is selected in the easy and medium stripping mode. The drive is turned on, the brush is brought to the part until its surface touches the edges of 4 beams of 3 piles located on the inner circumference, the required tension is set and the feed is turned on.

If there are small and medium projections and burrs on the surface of the part, only bundles 3, located on the inner circumference, operating in the mode of easy and medium stripping, participate in their removal. Bundles 3 of the pile, located on the outer circumference, remove only large protrusions and burrs, entering into work only when they appear and working in a more rational mode of coarse stripping. As a result, each bundle 3 works only with certain sizes of protrusions and burrs, removing them in the appropriate mode, which provides an increase in the productivity and quality of stripping.

The productivity and quality of stripping can also be achieved by performing a single-pass treatment, since it eliminates the need to tune or replace a tool or tool. The mechanism for adjusting the position of the cutting edge of the beams expands the technological capabilities of the brush, providing a wide range of materials and surfaces to be processed.

Claims (2)

1. A torsion brush, containing pile holders of wire bundles installed in a housing, and having the same length, and placed in two concentric circles, characterized in that, in order to improve the quality of processing, the pile tuft holders are arranged in such a way that the cutting edges of the pile bundles decrease from the center to the periphery. 2. Brush according to claim 1, characterized in that the pile-beam holders located on the outer circumference are mounted with the possibility of reciprocating movement in the direction; parallel to the axis of the brush. 2.
