RU1803309C - Granule of filler for vibration processing - Google Patents

Description

The manufacture and assembly of the proposed granule is carried out as follows. A core 1 is made, for example, by turning on a lathe group of a metal pipe, followed by drilling of radial holes 3, sheath rods 2 are made, for example, of wire with registration on the stamp of seats 4. Fasten the rods 2 with the seats with radial holes 3 of the core 1 are rotatable, the cutting edges 5 are applied, for example, by galvanic deposition of the diamond-containing layer and the filler granule for vibration processing is ready for operation. The core 1 can be made in the form of a sleeve, and the dimensions of the central hole of the sleeve are assigned on the condition that the workpiece can freely pass through it. The dimensions of the rods 2 are assigned on the condition that it is possible to handle hard-to-reach spots, and the diameter of the rods 2 can be made so that the required vibrational characteristics are provided. The number of radial openings 3 can be from 12 to 100 and is selected so as to ensure maximum placement of the rods 2. When the number of radial openings 3 is more than 100, granule production is complicated. The number of rods 2 placed in the radial hole 3 is one, while it is possible to continue placing the rods 2 in the seat 4 of the previous rod 2 with the formation of a chain of rods 2 (see Fig. 5), when connecting rods 2 no more than 4 pieces, with a larger the number of rods 2. bonded to each other worsens the working conditions of the granule. The rods 2 can be made either linear or curvilinear, while the magnitude of the curvature of the rods 2 is assigned so as to ensure maximum contact with the treated surfaces. The rods 2 can be made, for example, of U7A steel. The diameter of the radial hole 3 is determined from the condition that the rod 2 can be rotated relative to the core 1, as well as from the condition that the maximum number of radial holes 3 can be placed on the sleeve of the rod 2. The final fastening of the seat 4 after the pellet assembly can be performed, for example. by welding. The rods 2. located on the core can be made of different configurations and sizes.

For example, a granule consists of a core 1. made in the form of a sleeve with dimensions: Onar 20 MM. den - 16 MM, I 10 MM,

the number of radial holes - 36 pieces placed on two circles with coordinates from the ends of 3 mm and after 20 °,

the diameter of the radial holes is 2 mm; each rod has a single rod of straight shape, 40 mm long, 1 mm in diameter, and the diameter of the seat is 7 mm. material

U7A rod, core material 1 is steel 20, cutting edges 5 are galvanically deposited by a diamond-containing layer M20, final fastening of the seat 4 after the pellet is assembled by welding.

During processing, the granules are loaded together with the workpieces into a vibrocontainer, they include a device that moves the vibrocontainer in space. And the vibrodevice, the surfaces being cleaned come in contact with the cutting edges 5 of the rods 2 and core 1 and the parts are machined, while the rods 2 have the ability to align

make turns around the points of attachment, and

also to perform vibrations of different frequencies, while chaotic movement in volume, vibrocontainer. After finishing the processing, granules and processed parts are separated, for example, by means of separation gratings.

The use of the proposed granules for vibration processing allows to increase the processing productivity by increasing the mobility of the parts of the granule as a result of: .

- enabling independent movement of the rods relative to each other by placing the seats of the rods in the radial holes of the core one at a time;

- the appearance of additional chaotic movement of parts due to a change in the position of the center of gravity, since the rods can be made with different dimensions and different lengths depending on the rods connected to each other, - allowing the shell rod to make mutual turns and movements due to the possible implementation of the core in the form of interconnected rods, on the free end of which are formed seats for the rods of the shell,

- enabling the shell rods to make mutual turns and movements due to the possible flush of the rods composite.

enabling the parts of the shell to rotate relative to the core by placing the seats of the rods in the radial holes of the core with the possibility of rotation.

- the possibility of additional contact of the workpieces on the external contour due to the possibility of failing parts through the hole of the core sleeve,

- an increase in the contact surface of the sheathing clean elements with the parts being cleaned when the rods form different turning angles, due to the fastening of the rods with the core with the possibility of rotations, as well as the possible execution of the rods in a curved shape, as well as expanding technological capabilities by processing hard to reach places as a result of:

- increasing the penetrating ability of the parts of the granule due to the execution of the spruce in the form of separate rods having the possibility of independent rotation relative to each other, as well as relative to the core by bonding the seats of the rods with radial

rotatable core holes,

- the possibility of processing parts having inaccessible places in the form of grooves, crevices, pockets, etc.

. In addition, ease of separation of the machined parts and pellets, as well as ease of manufacture, is provided.
