SU369018A1 - VERTICAL PRESS FOR HYDROSTATIC PRESSING OF MATERIALS - Google Patents

Description

one

The invention relates to press-forging equipment for the manufacture of products by the method of hydrostatic pressing (pressing), and can also be used in installations designed to test for high pressure various types of products (pipes, vessels, etc.).

Vertical presses for hydrostatic pressing (pressing) of materials are known, comprising a movable high pressure container with a lid and a frame frame mounted through a support element on the foundation.

In order to increase the productivity of the bed of the proposed press, it is pivotally connected with the supporting element with the possibility of rotation in the vertical plane; In this case, the stapine can be made of two parts, each of which is hinged to the supporting element so that it can be rotated in a vertical plane.

FIG. I given the scheme of the press, front view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - option with one-piece bed.

The bed of the proposed press consists of two half-frames 1 and 2, loosely supported, they are on the axis 3 1 4, which are fixed in the bores of the support element 5 of the press. A container 6 is placed in the opening of the half-frames; bed frame press. The force of the press is transmitted through the cushions 8 and 9, having cylindrical surfaces with radii emanating from the centers of the axes 5 and 4, respectively.

Piston cylinders 10 are used to rotate the half-frames. The stroke of these hydro-cylinders is chosen so that, when open, the lures can be removed from the container lid. The container when open is supported on hydraulic jacks.

11, mounted, for example, on brackets

12, resting on the foundation.

The work of the press is carried out as follows.

After the end of the previously performed cycle, the press frame is in the open position, the lid is removed, and the container is mounted on the hydraulic jacks and in such a position that the gap between the supporting surface of the container and the surface of the bolsters

is about -. After loading the raw materials and pressing equipment, the container is closed with a lid.

In the cylindrical cavity of hydraulic cylinders

W is supplied with liquid under high pressure, and the pressure stations of the press are shifted to the working position. The pressure in the cavity of the hydraulic jacks is released and the liquid is fed under high pressure into the container. As a result, it goes down, the lid rises up to the stop in the frame. The container maintains a high pressure until the extrusion process is completed, after which the pressure is released.

Hydrojacks are fed into the cylindrical cavities by high pressure liquid, as a result of which the container rises,

D

the gap between the bottom and the lower crossbar, framed by the caps 9 with a semi-cylindrical surface.

After this, the semi-frames of the frame are moved apart to the extreme position, by supplying high-pressure fluid to the annular cavities of the hydraulic cylinders 10, the lid of the container is removed.

And the product is removed from the container. The cycle of work on this ends.

The design of the press in the version with one-piece bed, as well as the order of the press, are similar to those described above.
