The invention relates to volumetric vibration treatment and can be used to finish the surface of long products. According to the main author. St. No. 757305, a device for volumetric vibration processing of parts is known, which contains an elastic-suspended container that receives oscillations from a vibrator and internalizers that are installed with possible rotation about its horizontal axis, while the container is provided with receiving rotation from an individual drive and mounted on one of the end walls the container is flanged with a spindle, and the turners are made in the form of a multiple-feed spring, the turns of which are made of elastic anti-friction rods and Attached at one end on the spindle hose and from the opposite end, and over the entire length of the device - introduced into the latter end and intermediate separating rings Ii ij. A disadvantage of the known device is low productivity when processing long products due to the low intensity of the working medium movement in the central container area. The purpose of the invention: - increase productivity when processing long products. The set is achieved by the fact that, in a device for volumetric vibration treatment of parts, containing an elastically suspended container that oscillates from the vibrator and is located 1 and inside it, agitators mounted rotatably about its horizontal axis, while the container is provided with - receiving rotation from an individual the drive and a spindle with a flange mounted on one of the end walls of the coyteyner, and the sprocket is made in the form of a multiple-start spring, the turns of which are made of elastic Ant-freeze, 1K rods and fastened with one on the spindle flange, and from the opposite end along the entire length of the device - inserted into the last by end and intermediate separators amg., from the torg-p-th walls; ontyngra is placed additionally added to ycTpo; icT iO and equipped with an autonomous time-of-drive drive, the centrifugal and ends with a large number of turners are mounted — ms / ldu hard is fixed with EiF-jM i-ia centerpieces: and the flanges with openings along the holes. surroundings: 1 between the center and periphery of the blockage and the agitators and the instructor; K.A1 for installation of long products placed along the longitudinal sec of the container, after that the central nt-polken of separate ;; connecting-other PS Tortsag. elastic self; -: thin sections, besides, the areas of the district are equipped with ring linings and polycrystal l-4 and st; -cc, c vioHTHpOBaH i4MH with Boseposteg of adjusting the stiffness of uopughh by j. at the same time, KOirrefiiiep COCTOTIT by icpaP has a measure of six sections and at least three of them are elastically connected with autonomy. the vibration exciter, and on the elastic ses, the dagpocks for frequency of frequency 1, introduced into the UGoWoSTBO:::; leba 1i „. In FIG. i schematically depicts a prelagase device, sbch view, longitudinal section; vg1-l. lnenny with B111rypol in the BB section; ka Fng.E view A in FIG. 1, on the back end: the end liiecryio section, the device has a t case or an enclosure, consisting of -1-1: 5 of the front and rear end sections and four intermediate sections: 1. Cm with c: ections. The end sections have a CorttoB; gth wall: front 1 and back 2,, ii ;.- the wall and the front wall No. 1 and 2 are connected by four support and three drive sections. The sections contain thin-walled shells; and 3 with hatches for pumping liquid (; x), with Lokam15 ™ (5un {1-1 and 5i for loading) and hatches for melting Kfix parts (D, abrasives (A) and fillers (n).

Supporting on sa contain peckladin 4, lodgement :; , amplifying annular overlays;:. b tangential straps 7. Perekladikch 4 by means of gas-liquid (GZ) shock absorbers 8 are fixed “on the mounting platform 9. In its own turn, platform 9 is fixed on the slide by means of hydraulic jacks 10 as 11.

Driving gears contain additional rigid frames 12, in which sensors 13 are built in to control the i-th parameters of the pr (t mode operation of the device. Driving gears by gas-liquid springs 14 are connected to unbalance zibras 15, driven by direct current motors o

On the end walls 1 and 2 in bearings, 1: hl installed central spindd; g and 16 with agitators 17 and peripheral knuckles 18 with agitators 19. Attached to the rotary chuck: bcln are equipped with fluoroplastic protruding disks 20 serving dimf to see impacts when interacting beat with stops 21, installed on the shells of 3 sections.

For processing long products 22 together with small parts D or independently at a gtpindle x 16 installed discs 23 for securing the ends of products 22. In addition, similar perforated discs can be mounted on frames 12 and used as intermediate supports for small hard long products. For installation and removal of the products 22 are provided on the walls 1 and 2 of the hatches 24, and on the spindle x 18 - probesh 25.

In addition to TorOf., Between walls 1 and 2, gpikdel, G.I., 16 and 18, and disks 23 are installed elastic-elastic strips 26, which serve to prevent abrasive particles and fillers from falling between the rubbing surfaces. The adjustment of the tension level of the agitators 17 and 19 provides axial straps 27. For adjusting the bending stiffness of the entire working container, overhead spars 28 are provided, which are attached to the radial straps 29 themselves.

The device works the footing in a skinny way.

Container of working medium filling, install lengthy products to be processed 22 (additional loading is possible for joint processing of small parts

vibration exciters are activated, while spindle m 16 and 18 communicate rotation in opposite directions, thereby increasing the screw-like movement of the load in the central zone, improves the mixing of the load, provides more intensive and uniform processing of small parts and long products 22. Central tufts with their billows, they collide with the products 22, causing them to rotate together with the disks 23, and thereby create a vibrating separation zone between the peripheral and central helical-like flow ami

5 downloads. At the same time, intensive volume processing of products 22 is ensured.

Vibro-exciters, suspensions, connective sa and lining have

0 adjustable stiffness. This allows varying local stiffness and setting the container as a multi-span beam to various forms of oscillations with its own and partial frequencies that differ an odd number of times. Pa these

however, the exciters 15 with springs 14 are tuned to}. As a result, a resonant adjustment is performed at several frequencies at once, and a periodic total excitation in the form of a so-called rectangular sine is applied to the container. The spectrum of the spectrum is equal to 1def ;; and is regulated by the frequency spectrum of the natural oscillations of the pygosek1; ionic structure of the coneHepa.

At the same time, the average pathogen

0 is tuned to the fundamental frequency equal to the first company and the natural frequency of oscillation of the entire container. The side front pathogen adjusts the start-up three times the main one. The side rear driver tunes to a frequency five times higher than the main one. Such a re:: their excitation in the form of a rectangular sine is close to the so-called ideal law, which ensures the maximum producer HocTbf, since it dissipates in the load, the largest amount of energy is processed.

Thanks for the construction.

5 of the container is multi-element, at each excitation frequency between the joints of the sections oscillations occur according to the law of the rectangular sine function, i.e. dry friction that generates in the lining of the container additionally increases 11C1y. a series of odd frequencies. Due to this, high-frequency oscillations of the driver relative to the load are obtained. Due to

5 of this dry low frequency friction
