Abstract

The invention relates to the field of mechanical engineering, in particular to the construction of a polishing press. The purpose of the invention is to simplify the design. The polyspast press contains slider 5 mounted in the bed 1 guides. Along the perimeter and diagonal of the bed 1 and the sliders 5, expand the blocks 6, 7, covered by the flexible element 9, one end of which is fixed on the winch drum. The ram of the power cylinder is articulated with the tension block installed in the additional guide frames 13. The approach is carried out by a winch, the working stroke after locking by the latter is a ratchet mechanism under the action of the power cylinder. For return stroke, a return stroke winch is provided. 5 il.

The invention relates to mechanical engineering, namely to the design of forging and stamping equipment.

The purpose of the invention is to simplify the design,

FIG. 1 shows a press, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a layout of a flexible element.

The press press contains a bed 1 including a square plate 2 n hollow pillars 3, into which the south 4 slides 5, equipped with a square plate 2, are directed. The bed 1 and slider 5 have blocks 6 located along the perimeter and blocks 7, placed diagonally. Blocks 6 and 7 are connected to each other with a winch 8 by a flexible element, such as a rope 9.

The press is equipped with an additional polyspast consisting of the lower stationary 10 and the upper movable 11 blocks fixed between the two cheeks 12 of the frame 13 of the press. The mobile unit 11 is connected to the hydraulic cylinder 14 located above the swan-ky 8. The latter has an additional xfianoBoe wheel 15 interacting with the c-tank 16. The press is also equipped with an access | The winch 17 and two blocks 18 mounted on the frame 13. For the operation of the hydraulic cylinder | there is a pump station 19. The return winch 17 is connected to the slider 5 by the rope 20.

Polyspast press works as follows.

On the plate 2 bed 1 install the mold. Then winch 8 is turned on, which pushes the slider 5

to the mold. Then turn on the pump station 19, which supplies the working fluid to the hydraulic cylinder 14. The latter moves the block 11 to the upper position. Next, the bypass valve of the pumping station 19 opens and the winch 8 is turned on, which returns the block 11 to its initial position. Then the overflow valve is closed and the pump station 19 is again shifting the block 11 to the upper position by means of the hydraulic cylinder 14. After completion of the pressing by means of a return winch 17, releasing the paws 16, raise the slider 5 and remove the mold. The economic effect is achieved by simplifying the design and manufacturing of the proposed press.
