SU151945A1 - A device for cleaning shot surfaces of hollow parts - Google Patents

Description

Apparatus for cleaning with shotguns of hollow parts, such as tubes, are known, consisting of a rotating drum, at the ends of which nozzles are arranged. The devices used an elevator for returning a shot to work.

A distinctive feature of the described device is the use of swinging nozzles mounted, for example, on levers receiving a drive from the drum and providing a fraction of the fraction inside the drum.

This embodiment of the described device improves the quality of cleaning all surfaces of hollow parts, such as pipes.

FIG. 1 shows the described device, front view; in fig. 2 - view along arrow A; in fig. 3 - kinematic diagram of the device.

The device consists of a drive / rotation of the drum 2 for loading pipes, the device body 3, the drum support rollers 4, nozzles 5. The nozzles are rolled from the shaft 6 through the crank 7, the rod 8 and the rocker 9. At the end of the rocker arm, the lower nozzle is fixed . The upper nozzles receive a swinging movement from the yokes 9 through ti gi 10.

Thus, the lower nozzles, which swing in the upper plane, clean the inner surfaces of the pipes through the slot in the end sheets of the installation housing, and the upper nozzles clean their outer surfaces.

The interaction of rolling nozzles and rolling the tubes inside the drum creates a uniform cleaning of all surfaces of the pipes.

The shotgun cleaning device includes two shot-blasting columns P for feeding the nozzles, an elevator 12 and chutes 13 for filling the shot (metal sand) into the shot-blasting columns. Shotguns have two taps M for feeding the nozzles.

Through the door 15, pipes are loaded into the drum 2, the button for driving the drum is turned on, then the drive for the elevator 12, and the compressed air supply valve to the shot blasting units opens.

At the end of the cleaning, the pipes are discharged and the cycle is repeated.

Subject invention

A device for cleaning shot surfaces of hollow parts, such as pipes, which includes a rotating drum with nozzles located on the side of its ends, and an elevator is used to return the fraction to work, characterized in that, for the purpose of higher quality and cleaning of all surfaces of parts, rocking nozzles are used, installed, for example, on levers receiving a drive from a drum, and providing a fraction of the fraction inside the drum.
