Description

This invention relates to bristle-brush production.

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

FIG. 1 shows the step of making a brush; in fig. 2 shows the crimping operation of the cleaning elements. . ,;

A method of manufacturing the indric brush by installing cleaning elements 1 (bundles of wire pile) in the radial holes 2 of the cylindrical hollow body 3 with the non-working ends protruding into the internal cavity of the body 3, followed by fixing the non-working ends by inserting into the body 3 the cylindrical support core 4 and clamp non-working ends in the annular gap between the housing 3 and the core 4. Before installing the cleaning elements 1 in the radial holes 2 of the housing 3, they are placed in the holders 5 with the stops 6, and in the housing of the 3rd c. d t centering rod 7 impaled thereon technological sleeve 8 to limit the emission of non-working ends of cleaning elements 1. The top stops 6 total wear band 9 which eliminates the possibility of reverse movement of the treatment elements 1. The core 4 is performed hollow and

mounted on the rod 7 successively to the sleeve 8, while fixing the non-working ends of the cleaning elements 1 is carried out simultaneously with the removal of the technological sleeve 8 by acting on it with the core 4. Next, the holes 2 are compressed in which the cleaning elements 1 are installed with the help of holders 5 having at the end of the sharpening 10 by striking a hammer against the stops 6. Then, a light-melting substance is poured into the gap between the housing 3 and the core 4 in arrow A and the gap is closed with a conical insert.

Example. A rod with a diameter of 40 mm, a length of 500 mm and a process sleeve with an outer diameter of 60 mm and a length of 160 mm are used to manufacture the brush. The material of the core and process sleeve is steel 40X, heat-treated to HPC 55-62. The holders used for bending of the beams are made of tool steel U 10, HPC 55-60, holder diameter 4,5X. The stop and bandage are made of structural steel. The force P for moving the support core with the process sleeve is 500 kgf. For this purpose, use a screw press as a low-melting substance - an alloy VUD.

METHOD FOR PRODUCING A CYLINDRICAL BRUSH by installing cleaning elements in the radial holes of a cylindrical hollow body with the protrusion of their non-working ends into the internal cavity of the body with subsequent fixation of the non-working ends by inserting a cylindrical supporting core into the housing and clamping the non-working ends in an annular gap between the body and the core, that, in order to improve the quality of the brush, before installing the cleaning elements in the radial holes of the casing, a centering rod with the technological sleeve mounted on it to limit the departure of the non-working ends of the treatment elements, the core is hollow and mounted on the rod in series with the sleeve, while the non-working ends of the cleaning elements are fixed simultaneously with the removal of the technological sleeve by acting on the core.
