Description

11293244

This invention relates to electroplating electroplating devices.

The purpose of the invention is to improve the usability of the device.

The part that needs to be coated is connected to the negative pole of the current source, and the electrode 14 through the cartridge 13, sleeve 16, plate 18, slider 19, rheostat 10, ammeter 6 to switch 5 to the positive pole. Innings

The drawing shows the proposed device.

The electrolyte coating device W to the surface to be coated is made in the form of a gun. The inside is made by pressing the lever 7, case 1, made of two halves, an elastic electrolyte container 2 is mounted, sealed with a stopper 3, through which tube 4 15 is passed to supply the electrolyte to the

which rotates around the axis 8 by means of the insulating plate 9 squeezes the electrolyte from the elastic cylinder 2, which enters through the tube 4 to the surface to be coated. The operating current strength is established by creating a certain pressure force with the tampon-anode 15 on the surface to be coated, since the cartridge 13 moves the motor 19 of the rheostat 1Y through the sleeve 16 and the bar 18, while the bellows 20 is compressed. When the pressure lever 7 returns to its initial position, the cylinder 2 is straightened due to its elasticity, creating a discharge in the internal cavity, which returns the electrolyte from the tube 4 back to the cylinder 2, after which the volume of consumed electrolyte will be absorbed by the atmospheric air flowing through the anode end opening internal channel of tube 4. After this, the cycle of electrolyte supply is repeated as necessary. Replacing the device with a new batch of electrolyte is performed by replacing the empty cylinder 2 with a full one, for which you need to detach the bar 18 from the sleeve 17, unscrew the nut 22, then disconnecting the device case 1 into 2 parts, remove the cylinder 2, fill the cylinder with electrolyte and fix it in the device , production g specified ope

surface, a polarity switch 5 connected to a current source, an ammeter 6 (or a voltammeter) that controls the coating process, an electrolyte extrusion mechanism consisting of a lever 7 fixed on the axis 8, and an insulating plate 9 through which the lever 7 acts on the wall of the cylinder 2. Inside the case there is mounted a rheostat 10 for adjusting the current, spring loaded 11 and equipped with an adjusting screw 12. The collet chuck 13, which serves to fasten perforated graphite el electrode 14 with a swab-anode 15 fixed on its end, rigidly connected to a movable sleeve 16 telescopically connected

with the sleeve 17, wherein the collet of the chuck 13 and the sleeve 16 are made in the form of a single piece to which a lead-through strip 18 is attached with a detachable connection, which is rigidly connected with ensuring electrical contact with the resistor 19. Inside the telescopic joint, formed

which rotates around axis 8 by means of an isolation plate squeezes the electrolyte from the elastic cylinder 2, which enters through the tube 4 to the surface to be coated. The operating current is established by creating a certain pressure force with a tampon-anode 15 on the surface to be coated, since the cartridge 13 cages the sleeve 16 and the bar 18 moves the double-19 of the 1Y rheostat, while the sylph 20 is compressed. When the pressure lever 7 returns to its initial position, the cylinder 2 is rectified due to its elasticity, creating a discharge in the internal cavity, which returns the electrolyte from the tube 4 back to the cylinder 2, after which the volume of electrolyte consumed will be absorbed by the atmospheric air the anode opening through the internal channel of the tube 4. In this, the electrolyte supply cycle is repeated as necessary. Replacing the device with a new batch of electrolyte is carried out by replacing the empty cylinder 2 with a full one. in the device

bushes 16 and 17, a section of the tube with an easily changeable length is placed, 45 radios in the reverse afterwards, made in the form of a metal bellows 205 inserted into the incision of the tube 4 and inseparable with it sealed by an airtight connection, as well as 50 baking elastic interaction

ty, resulting in a restored-. The continuity of the electrical circuit of the device is present, and the device is prepared for operation.
