Description

Metal and Polishing Barrel < RTI ID = 0.0 >

The present invention relates to a metal and a glossy barrel, and more particularly, to a metal and a glossy barrel capable of shortening the plating time and minimizing the pressure loss to minimize the loss of the plating liquid.

As is well known, barrel plating is a method of plating a large number of small articles at a time, in which the articles and the articles are brought into contact with each other and frictionally polished, and the current is interrupted and plating is carried out by contact of the anode rod. At this time, it is important to use a material that does not corrode the plating solution first, and the plating solution must flow smoothly into the inside.

There are two types of barrel plating: horizontal and oblique. When a small object or a small amount is plated, an oblique type is used. When a passage through which the plating liquid flows into the barrel is clogged with impurities, Maintenance and cleaning should be easy.

Accordingly, conventionally used barrels are generally made of a synthetic resin material which does not react with a plating solution and are made into a cylindrical shape, and made of plastic injection in consideration of the manufacturing cost.

Regarding the conventional barrel plating as described above, the registered utility model No. 20-0229647 discloses a barrel for plating a small part, which is simple to manufacture and easy to repair and repair, and Patent Document No. 2002-62080 discloses a barrel for plating The lead wire and the electrode rod are fixed at a fixed interval without colliding with or being caught by the plated body, so that a large amount of plating liquid can be circulated in the barrel, and all of the plated body is immersed in the plating liquid to prevent bad plating. And Registration Practical Utility Model No. 20-0321491 discloses a barrel plating machine which improves plating speed by supplying a plating solution in a tank through a pipe provided with a pump and constituting an electrode in a coil system , Patent No. 10-0550860 discloses a barrel container in which a bushing member for supporting rotation of a barrel container and a barrel container A barrel-type plating apparatus for preventing abrasion of a barrel container by preventing a direct friction portion from being formed and preventing a plating failure due to a chipping phenomenon of a chip component, and Registration Practical Utility Model No. 20-0427364 discloses a rotary barrel- There is disclosed a barrel plating apparatus having an electrode structure in which an electric wire for transmitting a current, an electrode for supplying a current received from the electric wire to an electrolytic solution, and an electrode can be easily and easily separated for easy maintenance.

However, since the conventional barrel plating apparatus is configured to supply the plating liquid to the inside of the barrel from the outside of the barrel by using a pump to supply the plating liquid to the barrel installed in the plating tank, it takes about one hour per barrel until completion of plating The production speed of the product is low.

According to an aspect of the present invention, there is provided a barrel plating apparatus including: a cylindrical barrel having a plurality of holes formed in its outer circumferential surface, the barrel being horizontally installed so as to be rotatable in the plating vessel; A first pump for supplying a plating liquid in the plating tank to the branch pipe; a first pump provided on a circumferential surface of one side of the cylindrical barrel; A power supply unit connected to the anode and the anode through respective lead wires, and a driving motor for rotating the cylindrical barrel.

In addition, the barrel plating apparatus of the present invention includes first and second sensing devices respectively installed on the upper and lower portions of a plating bath to detect a plating solution, a wash water supply pipe installed to supply wash water to the branch pipes, a plating solution storage A second pump for supplying a plating liquid in the plating tank to the plating liquid storage tank; a storage liquid supply pipe for supplying a plating liquid stored in the plating liquid storage tank between the plating tank and the first pump; Controlling the supply of the cleaning water from the cleaning water supply pipe in accordance with the detection signals of the first and second sensing devices and controlling the supply of the plating liquid from the first pump to the branch pipe, A control unit for controlling supply of the plating liquid to the storage liquid supply pipe, controlling supply of the storage liquid from the storage liquid supply pipe, And a control unit for controlling the power supply unit.

According to the present invention, the plating liquid is supplied from the inside to the outside of the barrel in which the plating liquid is supplied from the outer side of the barrel to the inside of the barrel in which various heavy metals having high concentration are present, Since the plurality of anode rods are projected on the bottom of the barrel, the plating speed is improved and the pressure generation is minimized by the gradient formed in the holes of the barrel, thereby preventing adhesion of foreign matter.

Fig. 2 is a schematic view showing a detailed configuration of the barrel of Fig. 1;

A filter 30 is installed in the plating liquid supply pipe 22 between the plating vessel 20 and one end of the branch tube 12 provided in the axial direction of the barrel 10 to filter impurities in the plating liquid supplied to the branch pipe 12 And the first pump 40 and the first valve 42 are connected to the plating solution supply pipe 22 between the filter 30 and the plating tank 20 so as to supply the plating solution in the plating tank 20 to the filter 30 Respectively.

The plating liquid injected through the injection nozzle 14 flows in the plating liquid flow direction as shown by arrows in Figs. At this time, since the hole 2 of the barrel 10 is wide inside the barrel 10 and gradually becomes smaller toward the outside of the barrel 10, the plating liquid is rapidly moved from the inside to the outside of the barrel 10, The first pump 42 is continuously circulated by the operation of the first pump 40 while the first valve 42 is opened.

The anode rod 50 is installed on the bottom of one side circumferential surface of the barrel 10 so that only the distal end thereof is protruded while the anode rod 60 is deposited outside the barrel 10 in the plating vessel 20 And is connected to the power supply unit 70, that is, the rectifier by the lead wires 52 and 62, respectively.

First and second sensing devices 92 and 94 for sensing the plating solution are respectively installed on the upper and lower portions of the plating tank 20. A fourth valve 48 is provided between the filter 30 and the inlet of the branch pipe 12, A cleaning water supply pipe 32 is provided.
