Abstract

Usage: in the manufacture of shli-; fovovalno-polishing tool from an abrasive skin. SUMMARY OF THE INVENTION: a strip of abrasive skin is taken with a width equal to the length of the blade. Execute 1. petals connected to the rryjreM7 three-sided T-cuts of the willow strip / condition 1 of the jumper settings in the upper part of the petal. The petals are folded with an accordion, on the condition that their abrasive fio-surfaces are arranged in one direction. 4 ill.

The proposed method for manufacturing an abrasive block is implemented as follows; ;:, y: .-. ; . / / :: .. ;; ;;:;;

On the strip of the Sandpaper, ty-1 equal to the length of the petal Li, notches of the T-shaped form are filled. - In this case, incisions across the strip are made with a depth of at least the length of the working part of the lobe IV1, and longitudinal cuts a with a depth of at least 1/4 of the height of the lobe N. Then the working parts of the petal la x H are folded in a package, with the jumpers connecting the castle parts of the neighboring petals bend along the lines 1-1.2-2, 3-3, 4-4, ... and form an accordion. Thus, the | They make contact between the working parts of the unit once} 5, one by one, and the locking parts and the brackets are uniform / and form ut6l1 n% 1st, the same as the working part, the locking part. The thickness of the block in the areas of the aamka part is equal to the sum of the thickness cherished by yuev and perimetrically folded accordion. The first method proposed provides a comparison with the known effective use of abrasive material; which is confirmed by the following calculations; ;; V: ..:;. ; .. ....; A circle is known, the petals making up its blocks, made in the form of a plate with a side with many grooves forming the castle part (Fig. 4), where H is 50 mm.

to waste. In practice, the waste is even greater, because due to a sharp decrease in the elasticity of the circle as it approaches the maximum degree of wear, it is stopped when it is worn down to li IL

In the manufacture of a block of petals according to the proposed method, a part of the petal with an area of cnc is absent (Figs. 1 and 3), so a smaller amount of the skin is discarded, all other things being equal.

In addition, each Petal of the block is as if separated from the other, which increases the elasticity of the circle at maximum wear, as a result of which it is stopped when it is worn to li. where And If h E known case li -li 3-5 mm.

If necessary, increase the mechanical strength of the locking part of the block in

the trace can be glued with uniform contact surfaces.

Claims (1)

The claims 5 A method of manufacturing an abrasive block of a flap wheel in which petals connected by jumpers are made from a strip of abrasive skin and fold the petals with an accordion, provided that their abrasive surfaces are arranged in one direction, characterized in that in order to simplify the manufacturing technology, they take a strip of abrasive skin with a width of 15 equal to the length of the petal, and the petals with jumpers are made by T-shaped cuts of the strip according to the location of the jumper in the root of the petal.
