Description

Schi.1

The invention relates to mechanical engineering and can be used for the finishing treatment of parts in a vibrating container.

The purpose of the invention is the expansion of technological possible, i with a gut of providing control of the speed of the circulating movement of the mass of the load and its pressure in the region of the bottom of the working container.

FIG. 1 shows the device, a general view; Fig. 2 shows the position of the parts of the container of the device in the loaded state.

The device for vibration processing of parts contains a container consisting of working 1 and regulating 2 parts located one above the other and fixed on vibrating platforms 3 and 4. Vibrating platforms 3 and 4 are elastically mounted on base 5 and have rigidly fixed inertial vibrators 6 and 7. Between The working part 1 and the regulating part 2 of the container have a gap 8, which is closed from the outside by the transition element 9. The transition element 9 is located on the flange 10 of the working part 1 of the container, where it is held by its own weight, and on the generator The surfaces of the regulating part 2 of the container, while being able to freely move along the flange 10 and along the generatrix surface of the regulating part 2 of the container.

The device works as follows.

After the container is loaded, the working chute 1 receives working oscillations through the vibrating plate 3 from the vibrator 6, which determines the speed of the circulation movement of the loading mass. To regulate the speed of the circulating movement of the regulating part 2 by the vibrator 7 through the vibrating plate A, control oscillatory movements are reported which coincide or are out of phase with the working oscillations of the working part 1. At the same time, the transition element 9 slides along the flange 10 to close the gap 8 in any position working and regulating parts of the container. When the amplitudes and phases of oscillations of parts 1 and 2 of the container coincide, the speed of the circulation movement of the loading mass is maximum, the pressure in the region of the bottom of the container is minimum (for a given amplitude of the working part 1). As the amplitude of oscillations of the regulating part 2 decreases, the speed of the circulation movement of the loading mass decreases, while the pressure of the loading mass in the bottom area of the container increases. The amplitude of oscillation of the regulating part 2 can be reduced to zero and

further increase in antiphase with oscillations of the working part 1. By regulation, one can achieve a complete stop of the circulation movement of the container loading mass. The moment the circulation stops

Movement depends on the following factors: the mass of the working load of the container, the friction forces between the mass of the load and the inner walls of the container, the friction forces within the mass of the load, the amplitude and phase of oscillation of the working 1 and the regulating 2 parts of the container.

Thus, the regulation of the circulation velocity of the mass of the container load by means of the oscillation of a given

the amplitudes and phases of the regulating part 2 of the container allow one to regulate (increase) the pressure of the loading mass in the region of the bottom of the working part 1 of the container and intensify the process of vibration treatment.
