yCTMOgCA STRONG-AERASIVE PREPARATION OF 1 PARTS BEFORE 1SH1SHE1 & SHU1 P01-OPEN

The utility model is intended for processing over one part of parts that are suitable for subsequent spraying of wear-resistant coatings on them, or for cleaning parts from scale and contaminants.

A device for cleaning parts sections containing a camera, a jet-abrasive apparatus, a device for supplying parts to a working area, a device for holding parts in a working area in a type of fixed locks (USSR, AS M70390, g1ubl. 15.5.75, B24C3 / I2 )

The known device does not provide continuous processing of parts, has a low productivity of cleaning parts before spraying.

The purpose of the utility model is to eliminate these shortcomings, and most importantly, to increase the productivity of cleaning parts before the dust.

This goal is achieved by the fact that in the known device for cleaning, containing a camera, jet-abrasive apparatus, a device for feeding parts to the working area, a holding device, control is introduced. block, retractor fan, mechanism for rotating the part in the working area. The guide block consists of a power source, an electric motor, a time relay, a pneumatic valve and a pneumatic switch.

The device for feeding parts to the working area is made in the form of inclined trays placed inside the chamber, the retention device is made in the interior of the three-fork fork with ynopaivM connected to the control unit, the mechanism of the component in the working area is made in the form of a rubberized roller, and the jet-abrasive device in the form of a pneumatic gun .

In the drawing, the proposed installation is illustrated. It contains a chamber I in the form of a metal cabinet connected to an exhaust fan (not shown in the drawing), with a loading window 2 located in its upper part. Inside the chamber I there is a device for feeding parts 3 to the working area, made in the entrance of inclined trays 4 for loading 5 and unloading parts 3. The upper end of the tray 4 for loading is installed in the area of the loading window 2. in the form of a three-fork fork 6 with stops 7, 8, and 9, connected to a control unit 10, which includes a power supply II of electrical coupling 12, a relay 13 that is designed to be pulled by a three-fork fork 6 through a distributor 14 and a pneumatic cylinder SDR 15. For rotation children leu 3 in the working area is obrezinenry pojHiK 16 and abrasive supply proiskhodat through pressure gun 17.

Installation works as follows.

The loading of parts 3 into the installation is carried out through the loading window 2 in the upper part of chamber I and, according to their own weight, they slide along the inclined tray 1 to the retention device in the form of a three-arm VILES 6. When the power supply 1-cabinet II is turned on, the electric motor 12 of the control unit 10 drives rotational. movement of a rusty roller 16.

in the initial half-base; yiiop 7 - ARROW FLAP 6 covers the tray 4 and holds up the handle to process the part 3 After the time relay 13 is turned on, the pneumatic distributor 14 receives a signal to supply compressed air to the pneumatic cylinder 15.

In turn, the pneumatic cylinder 15 leads outside the tray 4 emphasis 7 and blocks the movement of parts 3 temporary emphasis 8.

After the first part 3 rolls up to the stop 8, the time relay 13 supplies the next signal to the air distributor 14 and with its help returns the tray of the air cylinder 15 to its original position. At the same time, the driver returns to the position at the same time to close the stop 7 and the temporary stop 8 is removed. The first part 3 is rolled onto the rubberized roller 16 and closed in this position by the stop 9, the pneumatic gun 17 is turned on and

the surface of the part 3 is processed. The rotation of the part 3 is carried out due to friction forces by it and the rubberized surface of the roller 16. After the specified processing time, which is installed on the time relay 13, the pneumatic cylinder 15 removes the stops 7 and 9, while blocking the movement of As a result, the machined part 3 rolls along the inclined discharge chute 5 and is removed outside the chamber I, and the next part 3 rolls up to the stop 8 and the installation is ready to repeat the cycle.

ZamBna parts in the zone of their processing zapleshlyaet 0.4-0.6 seconds, therefore, it occurs without turning off the air gun and electric motor rotating parts, which makes the processing process continuous. In addition, the abrasive that is loaded into the receiving hopper is fed into the pneumatic gun due to ejection and, when it enters the air stream, it accelerates to a speed of 15-25 m / s

The air-abrasive stream, falling on the surface to be treated, cleans it from contamination and eliminates the necessary roughness. Processing wire. In a closed cabinet, the PI used abrasive is reassembled in the receiving hopper and used further, providing 1Vaya: closed circuit (processing.
