Description

11233854

The invention relates to tools for removing from the surface of metals spike, rust, scale, burrs, for cutting metals.

The purpose of the invention is to increase the reliability of the pile crush.

FIG. 1 shows the proposed brush with a slit; Fig. 2 is a schematic of the fastening of the wire pile with a cut along the axis of the brush; in fig. 3 is a diagram of the fastening of the wire pile to the outside relative to the end surface of the brush. .

A cylindrical brush contains a bushing 1 with a boron divided by rings 2 mounted on it (J-shaped wire pile 3 and disk flanges 4 located at opposite ends of the disc for clamping the pile in the area of its working and non-working ends, having on the sides contacting the working ends Lint grooves 5 U. Parts of flanges 4 in contact with the non-working ends of AopiSa 3 also have grooves b, all the grooves 5 and 6 have a triangular profile with an apex angle of 55-65 ° and are made in the form of concentric; rings, centers which lie on the axis of the flanges 4.

The radius of the mounting hole 7 of the flanges 4, the radius of its peripheral cylindrical surface and the width of the pile set 3 at the base and the periphery of the flanges 4 are determined by the ratio

n is the number of rings in the set.

Due to the fact that the surface of the S1, the contact with the side surface of the pile, has annular grooves of a triangular profile with a corner at the apex of 55 to 65 °, is provided by-. Plastic deformation of the wire pile and thereby the reliability of its fastening. Located between the annular grooves of the projections of the trapezoidal profile can plastically deform the wire pile, without subjecting the cut.

Due to a certain ifflio ratio of the flange bore and its peripheral cylindrical surface and the width of the wire pile at the base and the periphery of the flanges, the pressure contact force is equal (1 pin with the side surface of the Pro Boloc pile in these areas and therefore a uniform pile density.
