Abstract

This invention relates to instrumental manufacturing and relates to flap wheel designs. The aim of the invention is to expand the technological capabilities of the flap wheels by providing machining of complexly shaped surfaces, such as oblique lifting of a shaft shoe. To do this, on the body of circle 1, packets of 2 petals are strengthened, in which each succeeding petal has a length and width greater than the previous one. The abrasive surfaces of the petals are directed towards the smallest petal. In this way, the shape of the packet of petals is brought closer to the shape of the surface being treated. 4 W1. FigM (L

Description

The invention relates to toolmaking, relating to the design of a blade; circles and can be used in the flax industry for the shaped outer surface of the shaft shoe.

The purpose of the invention is to expand the technological capabilities of the circle by providing machining of complex-shaped surfaces.

FIG. 1 shows the proposed circle, end view; in fig. 2 is a view A of FIG. 1 (with symmetrically located-petals in the package); in fig. 3 - the same, with asymmetrically located petals in the package; in fig. 4 - circle during the processing of oblique lifting of the shaft shoe blank.

The circle contains rigidly fixed on the periphery of the body 1, bags 2, assembled from a larger number of petals 3 of grinding sandpaper, having the shape of a rectangle. Depending on the profile of the treated surface, the petals in the bag may have a different arrangement, on. symmetrical example (fig. 2), with confusion about the axis of symmetry (fig. 3). In addition, the petals in the package can be recruited with different steps. Due to the variable width of the petals in the package, its working surface approaches the profile of the surface to be treated.

The circle is set at a distance from the surface to be treated, determined by the length of the smaller lobe in the bag. Round and Billet 4

(FIG. 4) report rotational motion in opposite directions. When in contact with the treated surface, the petals in the bag are bent and under the action of centrifugal force more intensively act on the product. The execution of the petals in a bag with different widths and lengths provides an increase in the duration of the circle action on the surface to be treated and the uniformity of the petals to the surface, creating a constant force at all points of contact.

in the case of mechanical fastening of the petals in the package, when the outer ends of the petals are worn, the latter can be reinstalled, which ensures maximum use of the petal circle.

Claims (1)

Formula: Flap abrasive wheel, made in the form of a case with packages of petals of abrasive cloth fixed on it, each subsequent petal in a package having a greater length than the previous one, with This petals are collected in the package so that their abrasive surface is directed towards the smaller petal, characterized in that, in order to expand the technological opportunities by providing machining of complexly-shaped surfaces, each subsequent petal in the package in the direction of the petal with a maximum length has a greater width than the previous one.  , dudА j o FIG. 2 Editor L.Povkhan Compiled by S.
