SU1518124A1 - Vibrating insert for moulding machine - Google Patents

Abstract

The invention relates to the production of precast concrete and reinforced concrete products and reduces energy consumption and creates ease of operation due to the fact that the causative agent of vertically directed power pulses in the vibration molding machine of the molding plants is made of 3 sections connected in series by means of quick couplings. Each section is provided with an elastic plate 5 placed under its drummer 4 with guide grooves and pins 11 with shock absorbers 10 mounted on them, located symmetrically to the drummer 4, connected by means of 14 and 14 lowering projections eccentrics 13 installed in the guide grooves and lower 16 overlays with pin 11 and riving eccentrics 13 fixed respectively and opposedly on them. Drummer 4 has a figured spacer 7 fixed to it and forming the working chamber 6 with elastic perforated proc. 8 and the elastic element 9, in contact with it and the inner surface of the housing. 5 il.

Isovrtepip) tsn: sitg, to the right of industrial production of concrete concrete and reinforced concrete.

The purpose of the invention is the reduction of energy consumption and the efficiency of operation.

On Lig.1 from (rdzhey vibromould molding ycTf iHOROK, section; on (bg.2 - section L- / in fig. 1; in fig. 3 node I in figure 1; in fig. 4 - section bb on 1; FIG. 5 is a section B-B of FIG.

The molding pad of the molding plant consists of a cylindrical closed body 1 with a guide tip 2. Inside the case 1 there is an exciter of vertically directed power impulses made composite of several sections connected in series by means of quick couplings 3. Each section contains a section drummer elastic plate 5.

The drummer k is made with a working chamber 6, bounded by a figured spacer 7 and an elastic perforated gasket 8, fastened with an elastic element 9 along the longitudinal axis of the hollow-venture.

The elastic plate 3 at the ends is provided on the placement side of the udawsh-i to the shock absorbers u mounted i: a pins x 11 mounted on the upper lining 1 /, fitted symmetrically to the shock 1, and from the opposite side to the eccentrics 13 on the opposite side, creased i): ; duo by means of tg 1 (with POM1CI (i-hinge 15 and with lower i-ia clutch 1b at the hinge of hinge 17. lining 12 and lower lining 1b are interconnected and move in the guide grooves 18 of the elastic plate 3.

Vibrating and molding installations works with / eduing.

After the installation of the vibrator bushing and the mounting of the concrete mix into the working chamber of the 6 sections of the exciter of the vertically directed power pulses, compressed air is supplied. The elastic element 9 rests on the inner surface of the housing 1, and the impactor, under the action of a pressure-free air 1, passed through the elastic perforated gasket 8, is removed (it is together with the elastic plate 5 relative to the initial position. When air breaks through the image, to the lower slit the elastic element 9 and elastic p.

With the gasket 8, the pressure in the chamber () of the chamber 6 drops, with the result that the hammer 4 returns to its original position by the action of the elastic plate 5. The impactor 4 strikes through the shaped spacer 7 and the elastic element 9 against the inner surface of the housing 1. Thereafter, the pressure in the working chamber 6 increases again, pressing the impactor again from the elastic element 9 and the cycle of the vibrator insert is repeated.

By decreasing the distance between the shock absorbers 10, the stiffness of the elastic plate 5 is changed, which affects the impact frequency of the striker.
