Abstract

The invention relates to forging equipment, in particular, to the construction of protective devices for fencing the working area of forging and pressing machines. The purpose of the invention is to increase reliability. In the upper position of the slider, the inserts 5 are mounted on top of each other and rest on a rigidly fixed lower insert. When the slider moves down, the copier tracks 7 interact with the rollers 9 and rotate the two shoulders levers 8, which turn the intermediate levers 10. The latter move the inserts 5 and the plates - the visors 2 upwards, closing the die space. 4 il.

Description

The invention relates to mechanical engineering, in particular to the design of press-forging equipment.

The purpose of the invention is to increase reliability.

FIG. 1 shows a protective device, a general view: in FIG. 2 shows section A-A in FIG. one; in fig. 3 - section bB in FIG. 1, with the lower arrangement of the slide, i.e. with the screen closed: in FIG. 4 - the same, with the upper arrangement of the slide, i.e. with the screen open.

The device contains a safety screen 1 in the form of plate-visors 2. And also a mechanism for moving the safety screen 1 with two nodes placed on both sides of the screen 1, each of which is designed as a guide 4 fixed on the base 3 of the machine with inserts placed in it 5 and mounted on the slider 6 copier track 7. Inserts 5 pivotally connected to each other, through a two-arm lever 8 with a roller 9 and an intermediate lever 10. The double-arm lever 8 is pivotally connected by a middle part with an insert 5 and one end - with an intermediate lever 8. Visor plates 2 of the screen 1 are rigidly fixed, each on one of the intermediate levers 10. The position 11 denotes a stamp. Paths 7 are made with a lead

part a - 18 ± G.

The device works as follows.

In the upper position of the slider 6, the inserts 5 are mounted on top of each other and rest on the rigidly fixed bottom insert 5. At the same time, the plate-visors 2 are folded and placed at the level of the connector's line of the stamp 11. As the slider 6 moves downwards, the track 7 interact with the rollers 9 and at the same time the corresponding two shoulders turn 8, which turn the intermediate levers 10, the latter move

inserts 5, and also plate-peaks 2 up. The safety shield 1 is thereby opened and protects the workspace. Upon further movement of the slide 6 downward, the track 7

the rollers 9 are held in the aforementioned state and the screen 1 remains open. After the technological operation is completed, the slider 6 returns to its original upper position and the operation of the mechanism for moving the safety screen is performed in reverse order, the screen 1 is folded in this way, opening the working area.

Claims (1)

Claims Protective device for fencing forging machine working area, comprising a base, a safety screen in the form of plate-visors, a mechanism for moving the safety screen with two nodes placed from two hundredDOH from the screen, each of which is designed as a fixedly connected slide track and fixed on the base of the slide with the inserts placed in it, on each of whose double-arm lever is pivotally mounted, on one shoulder of which a roller is mounted, and the other arm of which is articulated by means of an intermediate lever followed by a liner in the direction from the base, characterized in that, in order to increase reliability, the first insert from the base is fixed, and each plate-caps are rigidly connected to one of the intermediate levers. ggpf Ш№1 Aa 2 Jj BB
