The invention relates to the mechanization of work associated with sputtering, and can be used in mechanical engineering and other industries for the metallization of large parts.

The purpose of the invention is to expand the operational capabilities of the device.

Figure 1 shows the device, top view; figure 2 - section aa in figure 1.

The device comprises a metallization chamber 1 with a ventilation system and an assembly for fastening the product in the form of a drive spindle 2 with a center. A caliper 3 with a console 4 is placed on the outer side of the camera. At the end of the console there is a support node 6 with a metallizer 7 fixed on the balloon 5. On the support node 6 perpendicular to the axis of the spray head of the metalizer 7 there is a sliding bracket 8, which, using a screw 9 and a nut 10, fixed a shot blasting gun 11 with the possibility of rotation in the horizontal plane. The bottom of the metallization chamber has a hole with a conical tray 12 and a flap 13,

The device works as follows.

The support unit 6 is rotated on the hinge 5 so that the sliding arm 8 with a shot blasting gun 11 is inserted into the slits of the metallization chamber 1 and arranged at an inconsistent angle to the surface of the product 14. Next, using the sliding bracket 8, the required distance between the surface of the product is adjusted 14 and a nozzle of a shot-blasting pistol 11. When blasting the end surfaces, the shot blasting gun 11 rotates 90 to the axis of the sliding arm 8 and is fixed with the screw 9 and the nut 10. After the shot blasting gun 11 is adjusted, the product 14 with the spindle 2 rotates, the caliper 3 is fed into the shot blasting gun 11 with compressed air is fed into the shot and shot-blasting of the part 14 is performed. The spent shot in the conical tray 12 rolls into the hopper 15. After the shot-blasting is finished, the shot remains in the chamber are swept into current 12, and the hole in its bottom part is closed with a flap 13. This is done to prevent dust from getting into tray 12 and to preserve the efficiency of suction of gases and dust particles into the ventilation system by reducing the amount of air suction. By turning the support assembly 6, the bracket B with the shot blasting gun 11 is removed from the metallization chamber 1, the spray head of the metallizer 7 is inserted into it and the part is sprayed. Due to the fact that the shot blasting gun 11 automatically moves relative to the surface to be treated, the process of shot blasting of the part is carried out in a mechanized way. In addition, the execution of shot blasting of the product directly in the metallization chamber makes it possible to spray the coating almost immediately after the preparation of the surface, thereby significantly increasing the strength of its decantation with the substrate.
