Abstract

This invention relates to brush production. The purpose of the invention is to increase productivity. The brush manufacturing method is performed by making a groove on the brush body, forming tufts of the same length from a lengthy material, stacking the beams around the outer surface of the body, placing the non-working ends of the beams in the groove and fixing them in the groove. The operation of forming pile tufts is carried out simultaneously with the operation of stacking them around the outer surface of the body by rotating the latter and winding a long pile material on its outer surface followed by cutting loops on the body, so that the perimeter of the body in the winding plane is equal to twice the length of the working ends of the pile bunches. 5 il.

Description

The invention relates to the production of brush products and can be used in the manufacture of cylindrical (radial) and end brushes, which are used in everyday life or in production, in particular in polisher machines.

The purpose of the invention is to increase productivity

Fig. 1 shows a device for carrying out the brush manufacturing method, a general view; figure 2 - section aa in figure 1; FIG. 3 shows the order of laying a long pile material around the outer surface of the housing; 4 shows a cylindrical brush; figure 5 - ready face brush.

A method of making a brush consists in that, on the case of the brush 1, for example, an annular groove 2 is made, which may have a rectangular, circular cross-section

the shape or shape of the dovetail, form tufts 3 of equal length from a long pile material, stack them around the outer surface of the housing 1, place the non-working ends of the bundles in the groove 2 and fix them, for example, with the aid of ring pads 4. The pile is carried out simultaneously with the operation of laying it around the outer surface of the housing 1 by rotating the latter and winding a long pile material on its outer surface followed by cutting loops on the housing 1.

The method is carried out on a device in which the brush body 1 is installed in the rotation drive 5 so that the axis of rotation is perpendicular to the direction of the pile tufts. Simultaneously, a cyclic is provided.

rotation of the body in its plane "axis of the axis perpendicular to the axis of rotation of the drive 5; The beams of the frame are laid in such a way that they do not intersect the axis of rotation of the beam, angle v rchpen 60 ° C. Thanks to the atom after the ragrezr beams, their working ends are pairwise parallel, which increases the overall stiffness of the brush,

A brush body 1 is prepared in the form of a flange with grooves for securing the sorsa bundles in them. The flange i is fixed by its axis in the installation drive (see fig. 1), the actuator 5 is turned on and the flange begins to rotate around the axis, guided in the plane of the flange and perpendicular to the pile feed direction (the direction of the bundle of each bundle of pile). The flange is turned (manually or using a special drive — not shown in Figure) around its axis G. The rotation is carried out cyclically or continuously depending on the desired shape of the pile bundles and the lengthy material used. After filling the outer surface of the flange with pile bundles, it is removed from the drive 5 of the installation for the manufacture of a cylindrical or face brush.

When heating the radial brush (Fig. 4), the beams iOp., Ii are buried and clamped in the groove 2.,; The implanted ring pad 4, which has the same diameter as the flange; the outer diameter of the pad corresponds to the diameter of the flange; it is self-imperative (steel colio with a pharynx) or supplied with a fixed bolt. At the same time, the pile tufts are cut (chopped) from two sides of the flange in its center in the reverse sequence of the winding. The ends of the pile tufts cut in this way are spread out on the flange circumferences and serve as the U-shaped working ends of the radial brush. In the manufacture of the faceplate (Fig. 5), the tufts of the pile are clamped into the groove 2 also by means of an annular pad 4, which has a rectangular flow, like the groove. The outer diameter of the pad in this case does not correspond to the diameter of the flange, but is smaller. In this case, the block is also made either self-clamping or provided with a clamping bolt.

At the same time, the tufts of pile are also cut or chopped from two opposite sides (bases) of the flange, in its center, in the sequence of the reverse sequence of winding. The ends of the bunches of the pile thus cut are located on the base of the flange and serve as the working ends of the end brush.

If necessary, the working ends can be trimmed again in order to align the beams and give them a strict U-shape.

This method can be used in the manufacture of the end brush mop. In this case, the brush body is rotated around its longitudinal axis and moved (cyclically or continuously)

along this axis. The brush body is made, for example, cylindrical with two longitudinal opposite grooves, in one of which the non-working ends of tufts are clamped, and along the other groove

cut the working ends of the tufts of the pile. The diameter of the cylindrical body. (D) is selected from the condition D 2 1 / l, where I is the length of the working ends of the pile bundles. Long pile material is placed around the outer surface of the cylindrical brush body due to rotation of the brush body around its axis, perpendicular to the direction of the pile material supply, and due to cyclic or continuous movement of the body along this axis. Instead of moving the body, a movement of the fed material of the pile can be provided.

This ratio holds true for the case when the body of the nook is made in the form of a flange. However, in this case, the body does not move, but rotates around its axis. Therefore, the parameter t in this case is the time between two cycles of rotation of the brush body around its axis. This method is universal and allows you to make different types of brushes, radial face brushes, including mops on one device. The length of the working ends of the pile bundles is adjusted by simply changing the perimeter of the body brushes, i.e. The method allows the manufacture of a brush with a predetermined pile length.
