Abstract

The invention relates to electroplating, in particular to the coating of parts by the method of immersion into the melt. The aim of the invention is to improve the quality of processing by providing uniform coatings and cleaning the melt mirror before immersing parts and simplifying the design. The installation for immersion coating includes a bath 1 with melt 2, in which a container 4 is placed on bracket 3. A plate 5 is rigidly fixed above the melt mirror. Bath 1 is placed on a plate 6 moving in guides 7 with springs 8. A plate is mounted on a plate 6 9, in which the rod 10 moves, carrying the plug 11 with the pins 12. The pins 12 are exposed so that they come into contact with the hinge brackets 13 to which the caps are attached. When lowering the lifting and lowering device 19 with the panel 17 press on the rod 10, moves it down, the pins 12 of the fork 11 press on the console hinges 13 and open the covers. Going down further down, the rod 10 through the plug 11 presses the stop 15, compressing the spring 8 and lowering the plate 6 from the bath 1 until the level of the upper edges of the bath 1 is below the level of the upper edges of the container 4. At the same time the plate 5 sinks the melt of the vessel 4 sinks carbon and dirt, cleaning the immersion mirror of the parts 16. Then, the detail panel 17 is brought in and lowered into the melt by the required amount. After holding, the gripper 18 with panel 17 rises and all mechanisms operate in reverse order. Such an installation design allows improving the quality and uniformity of coatings and automating the process of coating products. 2 hp ff, 3 ill.

Description

The invention relates to equipment for coating, in particular, for plating parts by immersion.

The aim of the invention is to improve the quality of processing by providing uniform coatings and cleaning the melt mirror before immersing the parts and simplifying the design.

In Fig.1 and 2 shows the installation, General view; in FIG. 3, the installation at the moment of submerging the parts in the melt for coating.

Melt 2 is placed in the bath 1, in which at a certain depth a tank 4 is fixed fixedly relative to the bed with a tank 4, the upper edges of which are set horizontally to evenly melt 2. The plate 5 is fixed at a predetermined height above the bath 2 from a material not wetted by the melt 2. The height of its attachment is determined by the course of the lifting and lowering device.

The bath 1 is placed on the plate 6 moving in the guides 7 and held in the upper position by return springs 8. On the plate 6 there is a sleeve 9 in which the rod 10 moves, carrying the plug 11 with the pins 1 fixed on it. Pins 12 are exposed in such a way that they come into contact with the hinge brackets 13, to which 14 baths 1 are attached.

On the plate 6 there is also an adjustable stop 15, through which the lowering fork 11 transmits the downward movement of the plate 6 from the bath 1.

The parts 16 to be machined are inserted into the grooves of the horizontally located technological panel 17, and they protrude from its lower surface by a predetermined amount, taking into account the height of the applied coating. The panel 17 is held, lowered and raised when machining parts 16 by gripping 18 of the lifting and lowering device 19, which moves to a predetermined vapichina, and the rod 10 is lowered. Counterweight 20 returns the upper, initial position to block 10.

The installation works as follows.

The workpieces 16 are inserted into the technological panel 17 and, overhang from the bottom by a predetermined amount, are held above the bath 1 by the gripper 18 of the lifting and lowering device. 19. At this time, the kirsch 14 of the bath 1 is closed, the bath 1 itself and the stem 10 are in the upper position.

When lowering, the lifting and lowering device 19 with the panel 17 presses on the rod 10 and moves it down, the pins 12 of the fork 11, lower, press on the loops 13 and open the keys 14, further lowering the pins 12 keeps opening the covers 14 due to the withdrawal of the consoles of the hinges 13 to the side and slipping of the pins 12 along their ends.

Lowering down, the rod 10 through the plug 11 presses against the support 15, compressing the spring 8 and lowering the plate 6 with the bath 1 until the level of the upper edges of bath-1 is below the level of the upper cro-IOC capacity. 4, remaining stationary, while the plate 5 is also immersed in the melt of the container 4, depositing carbon and dirt, thereby cleaning the mirror for immersing the products 16.

Immediately after cleaning the melt mirror 2 in the tank 4, the panel 17 with the parts 16 is supplied to it and the tips of the parts 16 are dipped into the melt 2 to a predetermined depth. After the time required by the technology, the gripper 18 with panel 17 and parts 16 rises and all the mechanisms work in reverse order.

The design of the installation allows one to automate the process of coating products by immersion, since all the mechanisms of the installation are brought into the working mode from one team, and the productivity of labor sharply increases and the quality of coatings increases.
