Abstract

The invention relates to the processing of metals by pressure, in particular to devices for transferring a press washer (P) for reuse in core and pipe-profile presses on an ingot feeder. The aim of the invention is to increase the reliability of operation. The device comprises a base with guides, a hydraulic cylinder and a slide stop, mounted on the base, a slide with holding means P. The latter is made in the form of stepped supporting pins rigidly fixed in the slide. Spring-loaded sleeves are installed on the pins with the possibility of reciprocating movement. The holder is rigidly connected to the sleeves. The grippers are hinged on the sides of the holder with the possibility of movement in the horizontal plane. Under the action of the hydraulic cylinder U, it acts on the grips that rotate on the pins and pass P.

Description

one .

The invention relates to the field of metal forming and, in particular, to a device for transferring press washers for reuse in core and pipe profile presses on an ingot feeder.

The aim of the invention is to increase the reliability of the device.

FIG. 1 shows the device in the loading position, longitudinal section; FIG. 2 - the same, in the discharge position, a longitudinal section; in fig. 3 is a side view A of the holder; FIG. 4 - view B from above in the position of loading of the press washer, in FIG. 5 is a view of the B on the holder in the position of resetting the press washer.

The device for transferring the press washers contains a base 1, on which a hydraulic cylinder 2 with a stem 3 is mounted. Attached to a slider 4, which is installed with the possibility of horizontal movement on the guides 5 attached to the base. To crawler 4 are attached by holding pins 6, made with a ledge, on which are installed the sleeves 7, mounted in the lower part of the holder 8. In the sleeves 7, springs 9 are placed on the pins 6, one end abutting the pins of the pins 6, and the other in nuts 10, - fixed on the sleeves 7.

On the lateral sides of the holder there are hinges 11, on which grips are made with the ability to move in the horizontal plane, made in the form of two shoulders with outer shoulders 12, inner shoulders 13 and protrusions 14. Outer shoulders 12 levers at the ends have retaining ledges with conical chamfers . Between the inner shoulders 13 and the holder 8 are mounted on the spikes 15 of the spring 16. In base 1, the stop 17 and the receiving plates 18 located above the position of the press washer 19 on the ingot feeder 20 to the heated ingot 21 are mounted. For additional direction of the holder 8, a ha of 22 is provided. A platform 23 is provided to accumulate the press washers, and a hydraulically actuated pusher 24 is provided for moving the press washers.

The operation of the device is as follows.

In the initial position, the claws 12 are located above the receiving plates 18 and, abutting with the projections 14 against the holder, they are parallel to each other under the influence of the springs 13.

The holder 8 rests on the limiters 17. In this case, the slider 4 is retracted to its original position and the springs 9 under the action of the projections of the pins 6 are compressed, the pins 6 are flush with the end plane of the holder. Under the action of the hydraulic cylinder 2, the slider 4 with the holder 8 moves towards the platform 23. As soon as the holder 8 is retracted from the stop 17, the springs expand and the holder 8 under the action of the spring moves towards the slider, shifting the pins 6 grippers are brought to platform 23. Under the action of the hydraulic actuator 25, the press washer 19 acts on the conical chamfers of the levers 12, the levers rotate on the pins and pass the press washer, which is installed on the pins 6. After that, the grippers return When the springs are reset, the press washer is prevented from moving from the pins when moving.

Under the action of the hydraulic cylinder 2, the holder 8 with the press washer 19 is retracted to the stop of the holder 8 into the travel stop 17. The carriage with the pins continues to move to its original position, while the pins are recessed into the holder 8. The press washer falls into the plates, mounted on the feeder ingots 20 row with ingot 21.

The device allows to improve the transfer of the press washer to the ingot feeder, the reliability of its fastening increases, the possibility of supplying parts of various shapes is provided.
