Description

The known machines and devices for extracting pins from the anodes of electrolysis baths for the production of aluminum are complex in design and inconvenient in operation; the supporting innovations for them are the elements of the electrolysis baths.

In the described machine stranen these shortcomings. R: a.bota machines based on the effect of the impact force of the piston, compressed squeezed; by air.

The pneumatic percussion machine consists of a rod /, at one end of which there is a grip 2 with openings for connection with the pin head, and at the other end a buffer 3, which during operation of the machine strikes the piston 4, nailed to the rod / . The gripper 2 is connected to the pin head by a pin. Horse rod with buffer and piston is placed in the cylinder. The cylinder is closed from the side of the buffer 3 by a lid 5 with an opening 5, and from the opposite side by a lid 7 with a hole in the center through which the G reed T rod /.

For the supply and removal of compressed air, there are two holes 8 and 9 on the cylinder.

During operation of the machine, the cylinder space between the buffer 3 and the lid 5 is filled with compressed air. The cylinder is connected to the head by a pin 10. One end of the chain is attached to the cylinder, the other by means of a wedge // is connected to the head of the pin 12, for which a clip is attached between the grip and the head of the pin. Tightness in places where the mechanism is trained is provided with cuffs.

The cylinder is suspended To the frame 13 on the rod 14 with a thread and a flywheel 15, which allows the cylinder to be moved up and down. To move the frame and set the two wheels 16 rotary type.

No. 95288- 2 When it is necessary to remove the pin from the anode, the cylinder is installed coaxially with the pin; the head of the pin is associated with the pin of the machine and a wedge is laid between them. When a stream of flushed air nostruns into the cavity of the cylinder between the lid and the buffer, the chain 10 is tensioned, which creates a tight fit of the pin head to the grip.

The presence of two paired cranes, communicating the A and B cylinder bib with the source of compressed air or with the environment, makes it possible to regulate the non-mixing of the Norsh towards the buffer and OiSp.aTHo, while the piston moves towards the buffer, a blow occurs.

If the first blow does not entail aa extraction of the pin from the anode, the piston returns to its initial position after the compressed air has been poured, after which the blow is repeated.

The use of the description of the 1st machine mechanizes the process of removing nggyries from the anode and shortens the time of their extraction.

Subject invention

Mobile percussion pneumatic type machine for extracting pins from anodes of aluminum baths, consisting of a pneumatic cylinder, a gripping rod, a buffer, a piston and an air distributor in the form of two curved cork cranes, which is different in that it automatically ensures tight fitting. grip to pin head, working cylinder section with buffer pa two cavities, one of which is a piston, freely sliding along the rod, connecting the buffer with the grip, and the other being between the buffer During the operation of the machine, the lid and the lid are filled with compressed air, which de-energizes the constant tension of the flexible rod connecting the gripper to the cylinder, and the head of the pin fits snugly.
