Abstract

The invention relates to mechanical engineering, namely, to forging equipment. The purpose of the invention is to improve ease of operation. The device contains mounted on the slider (P) 1 of the press grip in the form of a screw 10 with a T-shaped head 2, hinged on P 1 power cylinder (C) 3, placed on P 1 sleeve 4 with internal thread and radial groove 5, located in the groove 5 is pivotally connected to the stem C 3 by one end and the lever (P) 7 rigidly connected to the grip 7. When P 7 rotates through C 3 to the extreme right position, the grip shoulders are installed along the groove made on the stamp plate 12 and simultaneously move on the thread of the sleeve 4, freeing the plate 12 strains a. Then P 1 rises and removes the grip from the zone of the plate 12 of the stamp. To secure the stamp, P 1 is lowered. The grip passes through the groove and rotates by means of C 3 and P 7. The grip shoulder engages with the plate 12 of the stamp and presses it against P 1. 2 Cp. f-ly, 2 ill.

The invention relates to mechanical engineering, namely, to forging equipment.

The aim of the invention is to improve ease of operation.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one.

The device contains a gripper with a T-shaped head 2 mounted on a table or a slider 1 of the press, a drive of rotating the gripper in the form of a hingedly mounted on the slider 1 of the power cylinder 3, placed on the slider 1 a sleeve 4 with a thread on its inner surface and radial a groove 5 located in the radial groove 5 of the sleeve 4 15 with the possibility of reciprocating movement along the axis of the sleeve 4 relative to the stem 6 of the power cylinder 3, hinged at one end to the rod 6, the other end rigidly connected to the gripper atom lever 7, as well as a safety mechanism in the form of two tension springs 8 and 9 placed one inside the other, connected to lever 7 and a slide. In this case, the grip is made in the form of a ramiper 7 rotates, tightening the screw 10, the shoulders of the T-shaped head 2 turns. vayt, engages with the plate 12 of the stamp and press it to the slider.

If there is no clamping force in the power cylinder 3, spontaneous release of the punch is prevented by springs 8 and 9.

Compared with the known technical solution, the proposed device has smaller dimensions and is more convenient for operation, since the rotation of the grip around its axis does not require a large working space.

Claims (3)

1. A device for fastening dies on a press, containing a gripper with an L-shaped head mounted on a press table or slider, a gripper turning drive in the form of a press of a power cylinder hinged on a table or a slider, as well as a safety mechanism and lever, with one end pivotally connected to the rod of the power cylinder, and the other end connected to the gripper, capable of interacting with 25, characterized in that, in order to increase the thread of the sleeve 4 of the screw 10, between the end face-ease of operation it is equipped with a sleeve 4 and a slider 1 placed on a press mounted on a table or slider gulirovanie gaskets 11, and between the T-bushing with a thread on its internal surface of the two gripper head and a plate 12 and a radial groove, the gripper is made of a stamp - adjusting gaskets 13 in the form of a plate 14 that can be inserted into the stamp 12 and acting with the threaded bushing of the screw, and the grooves of the market 15. the pitch is located in the radial groove of the bushing with the possibility of reciprocating The device works as follows. Moving along the axis of the sleeve relative to when moving the rod 6 in the extreme rod of the power cylinder and rigidly the right position of the gripper is turned connected with the gripper. by lever 7 at an angle at which 35 2. The device according to claim 1, characterized by the T-shaped shoulders of the gripper 2, is that the safety mechanism is designed as two tension springs placed one inside the other and connected to a lever and a table or a slider of a press. 40 3. The device according to claim 1, characterized in that it is provided placed between the ends of the sleeve and the table or slider tantalized along the groove 15, and at the same time moves along the thread of the sleeve 4, freeing the plate 12 of the stamp. Then the press slider 1 is raised and through the groove 15 removes the grip from the zone of the plate 12. The stamp is ready for replacement. To secure the new stamp, slider 1 is lowered. The grip passes through the groove 15 through the power cylinder 3 the press, as well as between the T-shaped gripping head and the die plate with shims. 0 the lever 7 is rotated, the screw 10 is screwed in, the T-shaped shoulders are 2 turns. vayt, engages with the plate 12 of the stamp and press it to the slider. If there is no clamping force in the power cylinder 3, spontaneous release of the punch is prevented by springs 8 and 9. Compared with the known technical solution, the proposed device has smaller dimensions and is more convenient for operation, since the rotation of the grip around its axis does not require a large working space. Invention Formula the press, as well as between the T-shaped gripping head and the die plate with shims.
