Description

(54) INSTALLATION FOR STABLING EXTRACTING

one

The invention relates to the processing of metals by pressure, in particular, to devices for the automatic processing of parts on a split matrix press.

A device for automatic punching is known, comprising a stamp with lower, intermediate and upper plates provided with a split matrix, a mechanism for: split pyrani matrix, a mechanism for loading workpieces and unloading finished parts, made in the form of two levers mounted for rotation at predetermined angles, respectively in the horizontal and vertical planes, and associated with the actuator 1.

A disadvantage of the known device is that when the deformed workpiece is fed into the matrix, it does not have time to turn off, which leads to a breakdown of the press.

The purpose of the invention is to increase the reliability of the installation due to the timely shutdown when the unmeasured workpiece is supplied.

The goal is achieved by the fact that the installation, containing a stamp with lower, intermediate and upper plates, equipped with a detachable matrix, device

for locking the detachable matrix, the mechanism for loading the blanks and unloading finished parts, made in the form of two levers installed rotatably at predetermined angles in the horizontal and vertical planes, respectively, and connected with the drive, is provided with a rotary plug installed in the path of the workpiece to the matrix with a flag, as well as a contactless controller interacting with it, a contact switch, the loading lever is equipped with pressure jaws, an additional proximity switch and fittings placed on it nnym on one of the flag sponges inclusion of the latter.

The stamp consists of an upper plate 1 fixed on a slider 2 of the press, an upper half-matrix 3, an ejector 4, an lower half-matrix 5 located on the intermediate plate 6. The plate 6 by means of skalok 7 passing through the holes in the lower plate 8 and the cross member 9 is connected with a plastic pad 10, which serves to lock the matrices. On the bottom plate 8, the punch 11 is strengthened, as well as the mechanism for loading and unloading the workpiece, consisting of three reversible pairs 12 (rails and three gears), the fuse sleeve 13. The loading lever for workpieces 14, on which the non-contact switch is fortified 15, is equipped with with a sponge 16, a squeezing sponge 17, on which the flag 18 is fortified. The squeezing and non-pressing sponges 16 and 17 are made with slots for passage through the truncated plug 19, the flag of which 20 is strengthened, interacting with the proximity switch 21. pnoy preform and receives drive from the drive pair 12. The line 23 along which the workpiece is moved vertically in the lower die 5 is fixed to the bracket. the loading of the workpieces 14 is rotated within the stops 24. The sleeve 25 serves to receive the heated workpiece. The vertical rail 26 is connected to the slider. 2. The installation works as follows. The loading lever blanks 14 fits under the sleeve 15, through which the heated billet. The slider 2 is in its lower position at this time. Then the slider 2 goes up and the rail 26, which actuates the load lever 14 through the gear line 12. After receiving the workpiece through the sleeve 25, the lever 14 starts moving to the matrix 5. By the arrow, if the lever 14 carries the workpiece, it turns on this the workpiece through the plug 19, the flag 20 and the contactless switch 21, the mechanism 10, i.e. the non-hydraulic cushion 10, which locks the half matrix 3 and 5. When the loading lever of the workpiece 14 reaches the stop 24, the workpiece becomes above the lower matrix 5, where it under its own weight, as the workpiece in gu kah pomeschaet-; with the gap, it is lowered vertically into the container of the matrix 5. Then the loading lever of the workpiece 14 leaves the stamping die and at the same time the slide 2 is lowered, under the action of which the semi-matrix 3 and 5 are closed before they are closed and then the semi-matrix 3 and 5 are closed , pressed by pneumatic-hydraulic cushion 10, since the passage and the workpiece through the plug 19 gives the maid to turn on the pneumatic-hydraulic cushion 10, continues to descend downward due to the remaining stroke of the slide 2, squeezing out the heated workpiece in the container below a half-matrix 5 between the punch 11 and the upper half-matrix 3 is provided to it. The lower position of the slider 2 corresponds to the stem part, which rises together with the upper matrix 3 fixed on the slider 2. with the stroke of the slider 2 through the gear pair 12. When the slider 2 rises upwards, the loading lever 14 at the same time with its jaws 16 and 17 will reposition the next workpiece and the cycle repeats. In the automatic operating mode of the press, there are cases when the workpiece cannot be lowered into the matrix container, 5, since with poor cutting of the workpieces, its ends have a large ellipse (i.e., see but the diameter) part of matrix 5 and stops halfway. The stand of the loading arm of the blanks 14 ends and it leaves the stamping zone, but since the workpiece is lowered into the lead-in portion of the die 5, the lever 14 cannot remove the workpiece from the stamping zone and floods it in an arbitrary setting. Sponge 17 is pressed. With the start of the stroke of the lever 14, the slider 2 also moves downward. In this case, the automatic device works: otzhipa sponge 17, opening, displays flag 18 from the contactless switch 15, which gives the command to stop the creep 2. The invention makes it possible to exclude cases of equipment breakage during the feeding of a non-finished billet. The invention The installation for stamping by extrusion, containing a stamp with lower, intermediate and upper plates, equipped with a detachable die, a device for locking the electrical matrix, a mechanism for loading workpieces and unloading finished parts, made in the form of two levers mounted for rotation angles, respectively, in the horizontal and vertical planes and associated with the output, characterized by the fact that, in order to increase reliability, it is provided with an installed pa of the way to move the workpiece to atritsu turning vplkoy with flazhko.m and vzai.modeystvuyuschim him a proximity switch, is equipped with a loading lever zazhimiy.mi 1ubkami placed on ne.m dopolpitelny.m contactless pereklyuchatele.m and mounted pas a sponge flag inclusion of the latter.
