Abstract

The invention relates to mechanical engineering and can be used in the finishing and hardening of parts. The purpose of the invention is the expansion of technological capabilities by ensuring the processing of large parts by increasing the rate of transition of the processed parts from one layer to another. The device consists of a rectangular-shaped container made of separate elastically connected with each other and a bed of 1 section 2, equipped with unbalance vibrators 3, which communicate to the sections a predetermined path of movement. The abrasive medium 4 and the workpiece 5 are loaded into the container. Next, the vibrators 3 are turned on so that each of them, with respect to the row located, rotates in the opposite direction. The mass of the load is divided into layers circulating in opposite directions 6 with the ratio of the height of the layers to their total width in cross section of 1/2/5/4. This allows the mass loading components to be easily redistributed over the container cross-section, which increases the intensity of their mixing. 1 dw., 2 tab.

The invention relates to mechanical engineering and can be used for finishing and hardening of parts.

The aim of the invention is the expansion of technological capabilities by ensuring the processing of large parts with an increase in the rate of transition of the processed parts from one layer to another.

The drawing shows a device that implements this method.

The device consists of a rectangular container made of individual elastically connected between themselves and the bed 1 sections 2, equipped with unbalance vibrators 3, which give section 2 a predetermined path of movement.

The method is carried out as follows.

The abrasive medium 4 and the workpieces 5 are loaded into the container, the vibrators 3 are turned on so that each of them rotates in the opposite direction relative to the row located, and the loading mass is divided into layers circulating in opposite directions 6 to their total width in cross section, which is 1 / 2-5 / 4, this allows the components of the loading mass to be easily redistributed over the container section, which increases the intensity of their mixing, and hence the productivity of ECCA processing after processing load weight is output outside the container and the cycle is repeated.

Example. The treatment was carried out on a vibration unit with a container with a capacity of 130 dm with a longitudinal separation into sections and with a container divided into sections across. Moreover, under each section of the containers an unbalance vibrator was installed,

Vibro-processing was subjected to parts of the type of rotation bodies C 10, mm) of aluminum alloy D16, parts were loaded into the container, and

working environment - PT-15. A 3% soda solution was used as a wash. The treatment was performed three times in the mode: the amplitude of oscillation was 2.5 mm; oscillation frequency 25 Hz. The initial surface roughness of the parts is 3.2, the target is 1.2 microns.

The test results are shown in the table.

The processing time between reversals was 15 minutes.

The data obtained show that in multilayer processing with the division of the mass of the load into layers along

container productivity of the process increases by 15-20%.
