(54) ПОДВИЖНАЯ РАМА СТАНИНЫ КОВОЧНОГО ПРЕССА(54) MOVING FRAME OF THE FORGING PRESS BED

1one

Изобретение относитс к прессо строению и может быть использовано, например, в гидравлических ковочных прессах с нижним приводом, станины которых В1 лючают подвижную раму, перемещающуюс относительно неподвижного основани .The invention relates to a press structure and can be used, for example, in bottom-driven hydraulic forging presses, the beds of which B1 include a movable frame moving relative to a fixed base.

Известна подвижна рама станины ковочного пресса, содержаща верхний и нижний ригели, соединенные между собой замкнутыми кольцевыми звень ми, установленными в симметричных выемках, выполненных на ригел х tl 1.A movable frame of a forging press bed is known, comprising upper and lower girders interconnected by closed ring units mounted in symmetrical recesses formed on girders tl 1.

Во врем работы, особенно при значительных эксцентричных нагрузках, несущие поверхности кольцевых звеньев и ригел этой рамы подвергаютс интенсивному износу, так как конструкци , будучи экономичной в изготовлении , не предусматривает их взаимного напр жени .During operation, especially under considerable eccentric loads, the bearing surfaces of the annular links and the transom of this frame are subjected to intense wear, since the structure, being economical to manufacture, does not provide for their mutual stress.

Целью изобретени вл етс получение напр женного соединени кольцевых звеньев рамы с верхним и нижним ригел ми, т.е. повышение срока службы.The aim of the invention is to obtain a tensioned connection of the ring links of the frame with the upper and lower bolts, i.e. increase in service life.

Указанна цель достигаетс тем, . что в подвижной раме станины ковочного пресса, содержащей верхний и нижний ригели, соединенные между собой замкнутыми кольцевыми звень ми , установленными в с1Ф1метричных выемках, выполненных на ригел х, на This goal is achieved by that in the movable frame of the bed of the forging press, containing the upper and lower girders interconnected by closed annular links installed in c1F1-metering recesses made on girders, on

Claims

FIG. Figure 1 shows the proposed frame, a general perspective view in Fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - section bb and fig.

2. The movable frame includes JEtBa solid closed ring links 1, complete in the link unit. On their inner surfaces in the upper and lower parts, the links are provided with protrusions, di which are matched with the corresponding grooves S on the planes 2 and 3. The bolts are connected to the ring links with П (моmorytsio shtlek 4. Inverted nahruh zhuh; side surfaces of the projections d, links 1, bearing pads of the corresponding grooves in the crossbars and self-braking wedge wedge 5 and 6 create wedge locks. When assembling the beams 2 and 3 are inserted into the ring elements 1 through the wide part of the opening in them (above and below the protrusions d) are moved before installation in the recesses of the beams and crepe with pre-studs 4. Then, parts 5 and 6 of the wedge are inserted into the Vig surface by means of the Vig surface. they end up with this operation It is tightened with a hydraulic jack 7 resting on the support 8 (in this case, the wedge b is moved downwards), which provides a tight connection. In the future, all hydraulic jacks can be removed with their replacement by measuring spacers.The support 9 and the removable spacer 10 make it easier to pre-assemble the new the lock, holding its elements in the position required for this. At the same time, the spacer 10 holds for disassembling the lock. 54 In this case, a special spacer (not shown) is used, allowing you to move down wedge pair pair 5. Spacer 10 is removed. The proposed movable frame is easy to manufacture and assemble. Connecting its parts with a wedge lock allows you to create a tension joint between them, which contributes to a significant increase in service life and reliability. Claims of the invention The movable frame of the forging press stinine, containing the upper and lower girders, interconnected by closed ring units installed in symmetrical recesses, you-. Filled with girders, characterized in that, in order to increase the life of the frame from the frame, on the internal surfaces of the closed ring links facing the surface of the crossbars, protrusions are made, and in the gap of the mesed the side surfaces of the grooves and the surfaces of the projections wedge locks are installed, while on a calzd a closed annular link under the upper crossbar and above the lower crossbar are stops for removable jacks serving to stress the elements of the frame.
