Description

FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular to hydro-impulse equipment.

The purpose of the invention is the expansion of technological capabilities by providing adjustment of the magnitude of the vibration amplitude of the vibrating table in vertical and horizontal planes.

Figure 1 shows the vibropress, General view; FIG. 2 is a section A — A in FIG. one; on fig.Z - section B - B in figure 2.

The hydraulic vibration vibropress contains a base 2 mounted on shock absorbers 1 with pulsator 3 and hydraulic cylinder 4 plunger 4 housed in it, rigidly connected to the vibration table 5. Hydraulic cylinder cavity 6 is connected via hydraulic actuator 7 in the vibrating table 5, in which guides 9 hangers placed between the cylindrical protrusions of the sliders 10 fixed to the ends of the levers 11. The levers 11 are fixed on the torsion shafts 12 placed in the sleeves 13 which are fixed to the frame 2. On Frame 2 is fixed brackets 14 limiters with adjusting screws 15 and nuts 16.

On the vibration table 5, a mounting plate 17 is placed on top, and a technological plate 18 is placed on the bottom. On the mounting plate, a matrix 19 with a processing object is installed. On the base 2, guide columns 20 are mounted, on which the upper cross member 21 is mounted, with pneumatic cylinder 22 of the installation movements. With the rod 23 of the cylinder 22, a movable yoke 24 is rigidly connected, on which inertial loads 25 are mounted. In the bore of the punch 26 a radial-thrust bearing 27 is placed.

Pulse vibropress works as follows.

When the pressure in the system corresponds to the pressure of the setting of the pulsator 3, the spool of the latter moves, compressing the spring, and communicates the cavity b with the hydraulic actuator 7. The plunger 4 moves upwards together with the vibration table 5 under pressure. The upward movement of the vibration table 4 causes the slides 10 to slide along the guides 9 as a result, the slider 10 rotates with the lever 11 relative to the axis of the torsion shaft 12, causing elastic twisting of the latter. At the same time, moving along the inclined planes of the guides 9 and interacting with them by cylindrical protrusions, the sliders 10 create a rotational moment relative to the vertical axis of the vibrating table, under the action of which the vibrating table 5 rotates around this axis,

Thus, the vibrating table 5 with the matrix 19 fixed on it with the object of processing performs a complex, namely, return-screw motion. The vibrating table 5 returns to its original position after the cessation of the pulse increase in pressure of the cavity 6 due to the energy stored during the elastic twisting of the torsion shaft 12. The oscillation amplitude of the vibrating table 5 is adjusted by screws 15 of the limiters.

Due to the inertial resistance of the movable cross member 24 with weights 25 to the movement of the matrix 19c with the object of processing, the latter is compacted.

When the vibrating table 5 returns to its initial position due to the shock interaction with the base 2 and the brackets 14 of the limiters, damped reciprocating oscillations occur, due to which, depending on the ratio of the pulse frequency and the natural vibration frequency of the vibrating table, the vibromachine and vibration modes are possible .

The pneumatic cylinder 22 is used for adjusting the movements of the movable cross member 24. The bearing 27 serves to transfer the pressing force to the processing object and allows the vibrating table 5 to be rotated together with the die 19 and the punch 26

around the vertical axis.
