Description

The invention relates to the deposition of electroplating on the surfaces of parts of complex configuration, mainly two-section sinks.

The aim of the invention is to improve the performance of the device.

FIG. 1 shows a device for the electrochemical treatment of products, a general view; in fig. 2 - the same, when performing an electrode from two parts.

The device for the electrochemical treatment of a two-section washing comprises a bath 1 for electrolyte 2. At the cathode 3 and anode 4 rods, the anode-cathode cell 6 for the product 7, which is made in the form of a support frame 8 and an electrode 9, is suspended by means of suspensions 5.

8 is equipped with guides by catchers 10 of the product 7. The shape of the electrode 9 facing the product 7 (working form) repeats the shape of the latter and is equipped with dielectric stops 11. On the stand 12 of the electrode

9 is installed roller 13, interacting with the cable 14, kinematically connected through the block 15 with the drive rotation of the electrode 9 (not shown). Dielectric bushes 16 are mounted on the cathode rod 3, on which the suspensions 5 of the frame 8 are placed. The suspensions 5 on the cathode 3 and the anode 4 rods are fixed by thumb screws 17. The dielectric bracket 18 of the suspensions 5 is fixed by means of a hinge 19 of electrode 20 the cathode rod 3 to the electrode 9 is implemented by a flexible current lead 21.

In the case of electrochemical machining of products of complex volumetric shape or large-sized electrode 9, they are made of two or more parts, each of which is hinged on its dielectric bracket 18 and equipped with its own rotary drive.

For electropolishing of a two-section washing, the anode-cathode cell 6 is suspended by means of suspensions 5 on rods 3 and 4. The cathode rod 3 is insulated from suspensions 5 by dielectric bushings 16. Suspension brackets 5 are fixed on rods 3 and 4 by thumb screws 17.

In the initial position, the electrode 9 is raised (rotated) to a vertical position. The auto operator lowers a two-part sink into the bath. Along guide catchers 10, product 7 lies with its edges on frame 8, against which it is pressed (not shown). The electrode 9 is lowered due to the fact that the shape of the working surface of the electrode 9 repeats the shape of the product, the distance between the electrode 9 and the treated surface of the two-section washing is the same over its entire area. Voltage is applied to the electrodes and the process is conducted according to the selected technology. After completion of the process, the electrode 9 is turned by a rotation drive to a vertical position. The operator removes the processed product 7 from the bath 1, and the whole cycle

processing is repeated.

The use of the proposed device for electrochemical processing of products allows speeding up the process of installation and removal of products, completely replacing the manual

labor and use of devices in both mechanized and automated electroplating lines. The manufacturability of processing products of complex volumetric shape is increased due to the smaller number of manipulations during installation and removal of products and replacement of the process of lifting the electrode to its cuff.
