Description

one

The invention relates to forging and pressing machinery, in particular, to the construction of devices for protecting the guiding surfaces of the sliding table and the lower traverse of the press against scale.

The purpose of the invention is to increase reliability.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 is a view B in FIG. 3; in fig. 5 shows a section B-B in FIG. 3

The device contains mounted on the sides of the table 1 elastic blades 2, mounted along the blades 2 on the lower traverse 3 trays with horizontal sections 4 and inclined taps 5, mounted on the table 1 arm 6 with trunnions 7 pivotally connected to the latter and placed from the end of the table 1 plate 8 with inclined scrapers 9 made of antifriction material fixed on them, springed relative to plates 8 by means of springs 10 graphite inserts 11 with longitudinal grooves 12, as well as elements 13 for centering inserts 11, placed in the plates 8 and passed through the grooves 12.

The plates 8 are made notches 14, where the inserts 11 and the springs 10 are placed, while the inserts are mounted between the scrapers 9. Seals 15 are installed between the plates 8 and the end of the table 1.

The device works as follows.

When forging forgings on the press, the dross falls into horizontal sections 4 of the chutes and is scraped when the table 1 moves with elastic vanes 2 into inclined bends 5. At the time of the press travel, the lower yoke 3 and table 1 are elastically deformed, which during pressure relief, i.e. forging.

leads to their mutual displacement and the occurrence of a vacuum in the gap between them. As a result, the air along with the scale is sucked into the gap between the guiding surfaces of the lower crosshead 3 and the table 1. When the table 1 is moved, scrapers 9 rake the scale towards the trays. Simultaneously, the graphite inserts 11, pressing under the action of the springs 10 to the lower cross bar 3, lubricate its guides

surface, which reduces wear. The technical and economic effect of the implementation of the invention is provided by an increase in reliability compared with the basic object.
