The invention relates to the field of vibration treatment and can be used to clean the burrs on the external surfaces of the parts.

The aim of the invention is to increase the productivity of the grinding treatment by creating zones on the surface of a granule with different vibrational properties.

FIG. 1 shows the proposed granule, general view, section; figure 2 - part of the scan cargo granules; in fig. 3 — granule made in the form of a body of revolution, cross section; in fig. k is the same, rectangular apered cross section; in fig. 5 - the same, triangular cross section.

The vibrating processing granule contains a shell 1 and a load 2 inside the shell 1, bonded with the shell 1, with notches 3 along the outer surface of the load 2, and the area of the ends of the notches 3 adjacent to the shell is 0, -0.8 square the outer surface of the cargo 2, covered by the shell 1, and the ratio of the areas of the ends of the largest and smallest notches 3 does not exceed the value 3: 1. t Make the proposed pellet as follows.

The load 2 is made of metal, for example, by machining on metal-cutting machines with the application of notches 3, sheath 1 is made, for example, by cutting out of a metal tape, cleaning elements k are applied to the surface of sheath 1, for example, by galvanic deposition of a diamond-containing layer and fasten the sheath 1 with a load of 2, for example, welding. The granule is ready to go.

The shell 1 granules can be made, for example, from steel 65G,

Do vibrating properties of different areas of the surface of the shell 1. The ratio of the area of the ends of the largest and smallest notches 3 can reach 3: 1, with a ratio greater than this value, the number of notches 3 on the shell 1 decreases and the quantitative range of differences in vibrational properties (vibrations) between different zones of the shell decreases. 1. The shape of load 2 can be arbitrary, for example, in the form of a ball, cylinder, cone, etc., and the outer surface area of shell 1 can be 2-100 cm. Thickness of shell 1 can be 0.1-1.0 mm depending on bridges of the weight of the part and the required vibration characteristics.

For example, the granule is made in the form of a cylinder with the following dimensions: outer diameter - 30 mm, height - 50 mm, shell thickness 1 - 0.3 mm, shell material 1 - 65G steel, cargo material 2 - Art. 10, the stripping elements C are galvanized by deposition of a diamond-containing layer, the notches 3 are made by drilling holes with diameters of 6 to 8 mm to a depth of 3 to 5 mm. The ratio of the area S to F (Fig. 2) is about 60%, where

The ratio of the areas of the ends of the most 40 (the largest and smallest notches 3 Up to two. The bonding of the shell 1 with the load 2 is welding. The parts are processed as follows. The cargo 2 is loaded into the hopper of the vibrating machine to make it out of item 10. Dimensions are granular granules and the parts to be processed depend on the dimensions of the processing, include a mechanism that allows usable details. Notches 3 on load 2 can provide spatial interchangeable, for example, by turning the vibrating hopper, the details of the grooves, drilling holes, at

This area of the ends of the grooves 3 should be 0.4-0.8 of the outer surface area of the cargo 2. When the ratio of the square of the ends of the grooves 3 to the area of the outer surface of the cargo 2 is less than 0.4 and when the ratio of the square of the ends of the grooves 3 to the external surface is cargo 2 more than 0.8, the bonding area of shell 1 and cargo 2 decreases, and differences between 55

After the stripping is completed, the vibratory tank mechanisms are disconnected and the machined parts are separated.

The use of these granules for vibratory processing improves processing performance by creating zones with non-uniform vibrational properties, since:

the shell is placed above the voids and the body of the load, when the workpiece contacts the zones located above the voids, vibrations of a higher frequency occur, and in case of a contact with zones located above the weight of the loads, vibrations of a lower frequency occur;

the shell, located above the voids, has springing properties and, in contact with the workpiece, gives it additional movement;

the shell placed above the voids is a membrane whose properties depend on the thickness, material and area of the voids, so that the surface of the shell is an alternation of zones with different vibrational properties, while the vibrational vibrations increase with increasing surface voids;

the vibration properties of the shell located above the voids depend on the place where the force of the part touches the shell and the vibrational vibrations increase towards the center of the part of the shell above the hollow;

The set of pellets loaded into the container may include pellets with a different percentage of the area of voids relative to the load J

The shell can be placed on a load with a different stress state, for example, in a stretched form between individual attachment points on the load.
