SU1488095A1 - Device for ejecting articles from from die set female die - Google Patents

Abstract

The invention relates to the processing of metals by pressure, in particular, to devices for removing parts from dies. The purpose of the invention is to expand the technological capabilities of the device and regulate the process of ejecting a part from the die. The device comprises a yoke connected by means of a ram to a press ram, a pusher and an ejector with an individual drive placed inside it. As the press ram moves upward, the yoke also rises and acts on the pusher, which separates the part from the die surface. The ejector drive is then turned on. The latter completely pushes the stamping out of the die. 2 Il.

(54) DEVICE FOR EXTRACTING DETAILS FROM STAMP MATRIX

(57) The invention relates to the processing of metals by pressure, in particular, to devices for removing parts from dies. The purpose of the invention is the expansion of the technological capabilities of the device and the regulation of the process of ejecting the part from the stem. The device comprises a yoke connected by means of a ram to a press ram, a pusher and an ejector with an individual drive placed inside it. As the press ram moves upward, the yoke also rises and acts on the pusher, which separates the part from the die surface. The drive then turns on. nod The latter completely pushes the stamping out of the die. 2 Il.

The invention relates to the processing of metals by pressure and, in particular, to devices for removing parts from dies.

The purpose of the invention is to expand the technological capabilities of the device.

Figure 1 shows the device, the appearance; figure 2 - section aa in figure 1.

The device comprises a yoke 1, connected by tami 2, passing through the holes in the press table 3, with the press slider 4 and fixed to the upper plate 5 of the stamp. On the press table 3, the bottom plate 6 of the stamp with the matrix 7 is fixed. In the center of the table 3 along the axis of the stamp with the matrix 7 there is a pusher 8 arranged to move along the axis of the stamp. The pusher 8 has an axial hole through which the pusher 9 passes, having a drive for reciprocating movement, for example, a pneumatic actuator 10. The stamp comprises a device for removing the punch 11 from the working area of the stamp consisting of guides 12 fixed on the top plate 5 of the stamp moving on them, the slider 13 with the support rod 14 and with the punch 11 fixed on it, the springs 15, the ends of which are fixed to the direction of the knob and the slider, and the wedge 16 fixed to the lower plate 6 of the stamp. On the latter there is a mechanism, for example, a pneumatic blower 17, for removing the stamped part 18 ejected from the matrix 7.

The device works as follows.

During the course of the slider 4 upward traverse 1 with the help of tg 2 rises, it rests against the pusher 8, which, moving along the axis of the punch, produces undermining from 4 00 00 O CO DM

of the pressed part 18 in the die 7. At the same time, the slider 13 with the punch 11 is extruded from the working area of the punch, since the roller 14 moves the slider 13 relative to the fixed bottom plate 6 and rolls along the wedge guide 16 and under the influence of springs 15 The punch moves the punch 11 out of the working area of the stamp and does not interfere with the further movement of the part. After that, the drive 10 and the ejector 9 turn on the full extrusion of the stamped part T8 from the matrix 7 and the part is thrown out of the last mechanism 17, then the drive 10 is turned on, which returns the ejector 9 to the initial lower position (in FIG. 1 and 2) the operation of the actuator 10 and the device 17 is not shown).
