Description

one

The invention relates to the processing of metals by pressure and can be used in the manufacture of beds of powerful vertical presses, such as hydraulic presses.

The bed of a powerful vertical press is known, containing upper and lower cross-beams assembled from beams, arranged between each other by a group of columns placed in pairs 1.

The disadvantages of the frame known design is:

-the metal capacity of the bed with its insufficient rigidity, since the beams of the upper and lower Rus work for bending;

-a large amount of machining in the manufacture of the lower cross member;

- a large amount of fitting work during installation.

The aim of the invention is to reduce the metal structure.

The goal is achieved by the fact that the lower cross member is made of two interconnecting layers of beams, each of which has two through holes, each pair of columns being installed in two openings of one of the upper beams and two adjacent openings beams. FIG. 1 shows a general view of the frame; in fig. 2 - section A-A of FIG. 1. The bed of a powerful vertical press

5 contains between the columns 1 the top 2 and the bottom fixed cross-beams. The lower fixed crossbar is made in the form of two layers of beams, fastened in height by columns 1. The balusters 3 of the lower layer are installed on the sides of the square and fixedly fastened together by strings 4. The beams of the upper torsion are made in the form of four brackets 5 installed at the joints of the beams 3

J5 of the lower layer and contacting each other with their upper planes.

When the press is working, the brackets 5 of the upper layer of the lower fixed crossbar take the load from the table of the press (not shown in the drawings), work in compression and transfer the load to the beams 3 of the lower layer so that they work in tension. This bed frame allows

25 to obtain, with a minimum of its metal intensity, maximum rigidity, which, in turn, improves the stamping accuracy. In addition, reducing to a minimum the number of connecting surfaces Rus

the lower cross member allows to reduce the amount of fitting work during installation, reducing it by approximately two times.
