Description

The invention relates to the field of forge and press engineering and can be used to create powerful presses with large dimensions of die space and horizontal presses of great effort, when the manufacture of a column-type bed or a bed composed of steel sheets becomes impractical or technically impossible.

Known press, mainly hydraulic, containing the frame with the upper and lower crossbars and racks installed between them, as well as bandages with a winding laid in them in the form of wire or tape, used to fasten the racks with crossbars.

The described press differs from the well-known fact that, in order to expand technological capabilities, reduce size and weight, as well as provide ease of maintenance, both cross-pieces have rectangular cuts at the junction points of the racks and are fastened to them by means of a detachable joint with sidewalls with rectangular grooves, windows formed with cut-outs, in which bandages are wrapped around the uprights and liners that mate with the inner surface of the tires and rest on the plane of the crossbars. In order to create conditions for the installation of BIBLIO I

PRESS

KI on the outer surface of the racks of nodes or parts of the press wire or tape can be placed inside the hollow rack. FIG. 1 shows a press with a cut along

rack axles, general view; in fig. 2 - device for power closure of wound wire or tape with bed parts by means of a bolt blocking the window in the traverse, a cut; in fig. 3 - wire placement or

ribbons inside the fields of the rack.

The press contains the upper yoke 1, the lower yoke 2, the movable yoke 3, the pillars 4, the bandage 5, the wound wire or tape 6, the bolt 7, remote gaskets

8, paired windows 9 in traverse and window 10 in traverse.

The upper yoke / and the lower yoke 2 are interconnected by posts 4. A wire or strip placed in the bandage holds the yokes / and .2 together and the stand, with each stand being attached to the supports separately, independently of the other stands. The size of the wound parts, in this case, the bandage, due to the size of the rack,

and not the whole frame, as it was in the presses of known designs. To ensure installation and disassembly of the band and the rack with 1 H 2 cross-beams, the latter are made detachable along the racks, and the wire or

The crest voltage of the racks is carried out by loading the frame to the design effort and the subsequent introduction between the crosshead / and the distance pads. The presence of independently fastened stands with traverses predetermines the possibility of any placement in order to ensure free access to the press space of the press from four sides. In addition, it is possible to carry out a three-post stand, fastened with wound wire or tape, which can be used, for example, in horizontal presses for pressing extrusion of rods, profiles, pipes, etc. The upper and lower traverses in a press of the above design can be used to accommodate cylinders and auxiliary devices, as is the case in presses, for example, column type. The preservation of the rectangular shape of the traverse is advantageous for the use of such beds in presses with significant bending moments in the limiting direction. In the case of fixing the bandal with the wound wire or tape on the cross-bars 7 and 2, when it is undesirable to make the cross-bars composite, windows 10 are provided. After installing the wound part with the wire or tape, bolts are inserted, then resting on the cross-bars. Placing a wire or ribbon inside a hollow rack is advisable when

the need to place on the racks any auxiliary devices, components or parts of the press. Obviously, the invention is not limited to the examples described above, but other uses and other embodiments that are not beyond the scope of the invention may be contemplated.

Subject invention

A press, preferably hydraulic, containing a bed with upper and lower crossbars and racks installed between them, as well as bandages with a wire or tape winding arranged in them, used to fasten the racks with crossbars, characterized in that, in order to expand technological capabilities, reducing size and weight, as well as providing ease of maintenance, both crossbars in the points of abutment of the uprights have rectangular cuts and are fitted with bonded: and

with them by means of detachable connection with sidewalls with rectangular grooves forming windows with cut-outs, in which bandages and sleeves are attached to the racks, which mate with the inner surface of the bands and rest on the plane of the crossbars.
