Abstract

The invention relates to press-forging equipment, namely, devices for changing dies on a press, and provides a simplified design. The device contains a support for the stamp (Sh) 1, which is located on the support with the possibility of interaction with Sh1 flexible element 2 with drive 3. The support is made in the form of 9 9 guiding (H) 4 and 5 angled to each other with limit stops 6, one of which is attached to the press bed 7, and the others are equipped with mechanisms with drive pushers for moving Ø 1, made in the form of a clamp 8, and hydraulic cylinders 9. H 4 is placed on one side of the press and executed with a central groove 10. The locking mechanism is made in the form placed in the groove 10 and the connection This flexible element 2 slider (P) 11 with a hole and connected to W 1 of the bracket 13 with a pin 14, which interacts with the hole P 11. When removing W 1 with P 11 and flexible element 2 W 1 moves to the left until it comes in contact with t; 8. Then, using the hydraulic cylinder 9 W 1, the clamp 8 moves from H 4 to H 5. The installation of W 1 from H 5 to the press is performed in the reverse order. The installation and stamp change is done automatically. 2 Il. i (L oo IsD O5 CO 00 vl J Fi.r-g - ff

Description

The invention relates to forging equipment, namely, to designs of devices intended for changing dies on a press.

The aim of the invention is to simplify the design of the device.

FIG. 1 shows a device, a plan; in fig. 2 - section aa in figure 1

The device contains a support for the stamp 1, which is located on the support with the possibility of interacting with the stamp 1 by means of a fixing mechanism, a flexible element 2 with a drive .3, wherein the support is made in the form of a friend located at an angle. to one another, guides 4 and 5 with limiters 6, one of which is attached to the base 7 of the press, and the others are equipped with mechanisms for moving the punch 1 with drive pushers made in the form of a clip 8 installed with the possibility of interaction with the limiters 6 and hydraulic cylinders 9 Attached to the bed 7 of the press, the guide 4 is placed on one side of the press and made with the central groove 10, and the locking mechanism is made as placed in the central groove 10 with the possibility of reciprocating and moving Kim element 2 polzushki 11c opening 12 and connected with the stamp 1 the bracket 13 with a pin 14 cooperating with a hole 12 polzushki 11.

The device works as follows.

In the initial position, the stamp 1 is placed on the die plate 15 of the press, the pin 14 is in the hole .12 of the slide, the drive 3 is disconnected, the clip 8 of the moving mechanism is pulled by the cylinder 9 before interacting with the stops 6 of the guides 4 and 5.

When the drive 3 is turned on, the stamp 1 by the flexible element 2 moves along the guide 4 until it contacts the clamp 8, after which the drive 3 is turned off and with the help of the cylinders 9 the stamp moves along the guide 5, where it remains in the storage and retrieval position.

The flexible element released from the pin 14 is moved by the actuator 3 until the hole 12 of the slider 11 is located coaxially with the pin 14 of the bracket 13, which is connected to the stamp intended for mounting on the press. The bracket 8 of this stamp is moved along the guides 5 until it touches the limiter 6 of the guide 4, while the pin 14 goes into the hole 12 and the drive 3 with the flexible element 2 moves the stamp 1 to the sub-die plate 15.

The device may contain any number of guides 5 with the corresponding number of spare stamps, guides 5 may be placed from different sides of the guide 4.

Compared with the known, the proposed device has a simpler structure.

Claims (1)

Invention Formula A device for changing dies on a press, containing a support and located on a support that can interact with the stamp by means of a fixing mechanism, a flexible element with a drive, the support being made in the form of guides with limiters, one of which is attached to the press frame, while others are equipped with mechanisms with drive pushers for moving the punch, which is distinctively due to the fact that, in order to simplify the design, a guide is attached to the press frame on one side The press mechanism is made with a central groove, the locking mechanism is made up of a guide placed in the central groove with the possibility of reciprocating movement and a slider with a flexible element with a hole, as well as connected to the die of the bracket with a pin, interacting with the slider hole, and the drive pusher of the mechanism for moving the stamp are executed in the form of interaction established with the possibility of engaging with the restraints of the bracket. 15 fpus, 2
