(54) PRESS TABLE

one

BACKGROUND OF THE INVENTION The invention relates to the forging of a forge-and-press machine-building industry.

Known stop ttressa containing mounted on it retractable frame.

The stop of a known design makes it impossible to test various devices working under pressure of the fluid, such as pillows, hydraulic or pneumatic, with the exception of those designed for this particular press.

Under production conditions, when a number of presses are working in the workshop, or in the case when the elements working under pressure of the fluid are produced in a separate flow and are installed in the press only with its general assembly, these elements must be tested before being installed in the machine, To achieve this, the minimum number of Tstroys of both a single press and a line.

In order to ensure the possibility of testing various press units operating under fluid pressure, the retractable frame mounted on the press table is equipped with two sliding

cross-beams having an individual drive mounted on a retractable frame.

FIG. 1 shows a mechanical table with the proposed table, a general view of FIG. 2 - Vic on top of the press table.

The mechanical hess has a detachable stand KIJiy i, consisting of yoke 2, struts 3 and table 4, joined into a single unit with pin 5. .

Table 4 has rails 9 on which sliding frame 11 (Fig. 2) with two movable crossbars 12, 13 is mounted on rollers 1O. Frame 11 is equipped with a movement of crossbars 12, 13, consisting of engine 14, gearbox 15, and gear. gears 16 and spindles 17, 18 interacting with spindles provided in crossmembers 12, 13.

The frame 11 is also equipped with a drive for its movement, including an electric motor 19 and a gearbox 2 O.

Inside the foot there is an oil reservoir 21.

Mechanical press works as follows.

By moving the sliding frame, the rollers 10 and the frame are rotated AND rolled out of the press. The drive of the crossbars 12, 13 is switched on, and the beams 12, jo 13 are moved along the guide screws to the required distance between them equal to the distance between the seats of the tested unit. such as pillows. The test assembly is fixed (fasteners are not shown in the drawings) and frame 11, 15 is reintroduced into the press. Thereafter, fluid inlet elements are connected (not shown in the drawing). The press is ready for testing.

Turning on the actuator 6 is driven by 20

slider 8. Slider, down, puts pressure on the test site.

The presence of the sliding crossbars of the sliding table makes it possible to test various parts of mechanical presses working under pressure of the fluid on one press, thereby reducing the time of assembly and testing of the press standing in the press line and installing the already tested unit on the newly built machine. .
