Abstract

The invention relates to forging machinery, in particular to the design of punching presses. The purpose of the invention is to increase reliability. To prevent the slider 5 from lowering, the handle 18 and the screw pair 17 move the rectangular beam 11 under the slide 5. With this, the projection, 12 of the beam 11 limits the movement of the beam 11, and the bevel 13 through the limit switch 6 trips the press. 3 il.

1 The invention relates to forging and manufacturing machinery, in particular to the trunking machinery of the press: 444b1x presses.

i The purpose of the invention is to increase reliability.

i FIG. 1 shows a press, a general view;

in fig. 2 is a view A of FIG. one; in fig. 3 -

section bb in fig. 2

The press contains a frame in the form of pillars 1 and crossbars 2 and 3, placed in the direction of 1 and 4 beds of the slide 5, as well as a block for preventing the lowering of the slide in the form of a block, a limit switch 6 connected by jro with a control system (not shown) hpeccoM, and the stop installed in the unit. 1 The block is made in the form of two brackets 7 and 8 fixed on racks 1 and 8 with shelves | 9 and lids 10. The stop is made in the form of an ax - | 7; And 8 between them and the covers 10 on the shelves 9.

The press also contains balancing, 1, and pneumatic cylinders 14 of the slide 5, which is connected to the eccentric shaft 16 by means of a connecting rod 15. A beam movement drive. 11 is made in the form of a screw pair 17 s, 1 hand grip 18.

The press works as follows.

When the eccentric shaft 16 is rotated through the connecting rod 15, the reciprocating nocTyhaTejjbHoe is moved by the slider 5. In the case of the need for adjusting the stamp in the upper positions of the rammer 5 by means of the handle 18 AND the screw pair 17,

d t is the movement of the beam 11 so that its upper surface of the surface turns out to be under 3yHoj, 5,, G1ri IT.M its protrusion 12 abuts against the bracket, limiting further movement of the beam 11, while at the beginning of the movement of the beam 11 it bevels 13 presses the limit switch 6, thereby disconnecting the press control system. The technical and economic effect of the implementation of the invention is provided by an increase in reliability as compared with the basic object.

Claims (1)

Invention Formula A punch press containing a frame in the form of racks and crossbars, placed in the guides of the base of the slide, as well as a block for preventing the lowering of the slide in the form of a block, a limit switch associated with the press control system, and an emphasis installed in the block with the possibility of interaction with the slide and a finite switch, characterized in that, in order to increase hopefulness, the block is made in the form of two fixed, on racks brackets with shelves and covers, the stop is made in the form of a rectangular beam with a protrusion and a bevel, The beam is housed in brackets between them and the lids on the said shelves with the possibility of beveling with the limit switch and the projection with the corresponding bracket.
