Description

The invention relates to equipment used in electroplating, in particular to suspensions for galvanic processing, and can be used to hold anodes or coated products.

From the publication (utility model patent No. 27596 U1, IPC C25D 17/06 published: 02/10/2003) a hanging device for chrome plating split gauges is known that contains a clamping device hook made of channels and fastening bolts. Split gauges that have undergone pre-mechanical, chemical and thermal treatment are inserted into the grooves of paired channels. This hanging device is attached to a conductive surface using a hook and is lowered into a bath filled with electrolyte preheated to a certain temperature, with anodes suspended in it. The part is heated for several minutes in an electrolyte solution without current, then a reverse current equal in density to the required forward current is turned on for 30 seconds, after which the forward current is turned on. After the chrome plating process, the time of which is determined experimentally, a new batch of parts is installed.

The disadvantage of this device is the high metal consumption and the need to insulate a large area of clamps made from massive blanks in the form of a channel. Disadvantages also include the presence of threaded connections, which may become unusable over time due to the aggressive environment of the electrolyte.

Based on the set of essential features, a suspension device was selected as a prototype, which contains a base, current-carrying bars, current leads, protected by a durable coating, with point contacts on their tips and a clamping device, while the edges of the current leads are made in the form of forks, and the plane of one fork is rotated relative to the plane the other at an angle of 80-100 degrees. The suspension contains a base, current-carrying bars, current leads, protected by a durable coating, with point contacts at their tips, wherein the current leads are made to hold flat products, and the tips of the current leads are made in the form of forks, with the plane of one fork rotated relative to the plane of the other at an angle of 80- 100° (patent RU No. 2636341 C, IPC C25D 17/06, publ.: 11.22.2017, bulletin No. 33).

The disadvantage of using this device is the irrational shape of the current conductors, which covers the useful area of the bath, which reduces the productivity of the galvanic process of metal deposition.

An invention is proposed that is aimed at eliminating the above-mentioned disadvantages, due to the holder for quick replacement and fixation of anodes or coated products.

The technical problem is the creation of a fast, reliable, small-sized mechanism for fixing anodes or coated parts during galvanic processes of metal deposition.

The technical result is to increase the throughput of the bath, ensuring high productivity of the galvanic process of metal deposition due to the rapid removal and installation of anodes or coated products in a holder, centering and fixing in which is carried out by leaf clamps. Fixation with clamps is ensured by a retracting rod, a cylindrical body and an extension spring.

A holder for anodes or coated products, containing a hook, a housing cover, a lower thrust nut for fastening the upper rod, an extension spring, an upper spring stop, a cylindrical body, a pressure axis, a leaf clamp suspension, leaf clamps, a nut for fastening the leaf clamp suspension to the retracting rod, a retractor rod, lower spring stop, nut for fastening the lower spring stop, nut for fastening the upper spring stop, upper rod, hook fastening nut, characterized in that it is technically equipped with a system for fixing anodes or coated products, leaf clamps mounted on a suspension attached to the retracting rod, tending in the opposite direction upward from the lower part of the housing under the action of a tension spring, and the petal clamps are made to rest against the cylindrical body when moving upward with the rear, involute-shaped side so that the lower ends of the petal clamps carry out counter-movement horizontally, fixing the anode or covered product.

The inventive device is illustrated in Fig. 1.

The claimed device consists of the following elements:

1 - hook, 2 - housing cover, 3 - lower thrust nut securing the upper rod, 4 - extension spring, 5 - upper spring stop, 6 - cylindrical body, 7 - pressure axis, 8 - leaf clamp suspension, 9 - leaf clamps, 10 - nut securing the leaf clamp suspension to the retracting rod, 11 - retracting rod, 12 - lower spring stop, 13 - nut securing the lower spring stop, 14 - nut securing the upper spring stop, 15 - upper rod, 16 - nut securing the hook.

The cover 2 is screwed onto the upper threaded part of the cylindrical body 6. The lower stop 12 is inserted into the tension spring 4, the retracting rod 11 is inserted into the hole of the lower stop 12 and the nut 13 is screwed on. The leaf clamp suspension 8 is placed on the lower part of the retracting rod and secured with a nut 10. The suspension is hung with leaf clamps 9 through the grooves. The upper stop 5 is inserted into the upper part of the spring 4, the upper rod is inserted into the hole of the upper stop 5 and secured with a nut 14. A thrust nut 3 is screwed into the upper part of the rod 15. All these parts are assembled in series (item 4 , 5, 8, 9, 10, 11, 12, 13, 14, 15) are collectively placed in a cylindrical body 6 so that the upper rod 15 enters from the inside into the hole of the body cover 2 until it contacts the nut 3. Next, a hook 1 is placed on the upper part of the rod 15, located on the outside of the housing cover 2, and secured with a nut 16. The pressure axis 7 is inserted into one of the grooves of the cylindrical body 6, then the axis 7 is moved towards the retracting rod 11 and centered with the hole in the retracting rod 11 Next, the axis 7 is moved towards the groove on the opposite side on the body 6, until a symmetrical arrangement of the axis 7 relative to the cylindrical body 6 is achieved.

Reliable and quick fixation of anodes and coated products is achieved due to the fact that the holder is equipped with leaf clamps and a retracting rod with an extension spring.

The device works as follows. The pressure axis 7 is pulled in the opposite direction from the hook, while the spring 4 is stretched, the retracting rod 11 moves down, the petal clamps are released from the cylindrical body 6. The anode or the product to be coated is installed in the petal clamps 9. When the pressure on the pressure shaft 7 is weakened, the spring 4 compresses and pulls the rod 11 with the suspension 8 and petal clamps 9 into the cylindrical body 6. The petal clamps 9 rest with their back side against the cylindrical body 6 and, as they move inward, they compress and fix the anode or the product being coated.

Creating a holder for anodes or coated products will allow you to quickly change anodes or coated products, depending on the work performed, which will increase the throughput of the bath and ensure high productivity of the galvanic process.
