Abstract

PURPOSE:To obtain a titled plating device which plates objects to be plated of single or dissimilar kinds simultaneously in large quantities and increases the speed of plating by providing a revolving shaft to a cylindrical cell which is disposed with a removing tray in a segmented part and is combined with plural sectoral cylindrical cells and providing suspending means for objects to be plated which extend arms above the revolving shaft and are movable vertically. CONSTITUTION:When a revolving shaft 11 revolves clockwise in the case of, for example, chromium plating, chromium plating solns. are filled in plating cellsI- IV. Water is put in a washing tank V, and in the position of a removing tray 8 disposed in a segmented part, objects to be plated are mounted to suspending means 13 provided to the preceding ends of the arms 12 of the shaft 11 which is moved upward beforehand. Thereafter, the shaft 11 is rotated 60 deg. intermittently and is moved downward to dip the objects into the plating soln. in the cellIand to plate the objects while moving the same. Such operations are repeated until finally the objects are dipped in the tank V and when the washed objects come to the tray 8, the objects are removed manually or automatically from the means 13 and are placed on the tray 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for plating a single type or different types of objects at the same time.
This invention relates to a cylindrical plating device that performs manual or automatic plating and increases the plating speed.

Conventional plating equipment drills a hole under the floor surface and stores the plating tank inside, and uses a large factory floor area, so it requires a large site and is difficult to install in areas where land prices are high. It was uneconomical.

In addition, plating work generally takes a long time, and the area to be plated is 1
For 0'Od, Dc was 10~30Δ, 30~2O (plating thickness: about 000), and it was not advantageous in terms of delivery time.

This invention is an attempt to improve the unsatisfactory points of the above-mentioned prior art, and its gist is that the plating tank is compactly cylindrical, the cylinder is divided into fan shapes, and each fan-shaped cylindrical tank is plated with the same or different types. Fill the liquid or washing liquid, place a take-out tray in the cylindrical part, provide a rotating shaft in the middle of the cylinder L, and extend arms radially from both sides of the rotating shaft. A device for hanging objects to be plated is attached, and the entire cylindrical tank can be raised and lowered, and the rotating shaft can be moved up and down, so that the cylindrical tank and the rotating shaft can be moved relative to each other.

The configuration will be explained below based on an example diagram.

Figure 1 is a perspective view of the main parts showing the structure, Figures 2 to S show the cylindrical tank, Figure 2 is a front view, Figure 3 is a left side view, Figure 7 is a plan view, FIG. 5 is an enlarged sectional view taken along the line A--A in FIG. 2, FIG. 4 is a perspective view of the take-out tray, and FIG. 7 is a perspective view of the fan-shaped cylindrical tank.

In the illustrated example, the fan-shaped cylindrical tank 2 has a circumference of 5.
They are connected together, and a take-out plate g is provided at the place where the circle is missing. The fan-shaped cylindrical tank 2 has a flange l on the upper part, and a liquid reservoir part S is formed in the center with a partition wall B in the radial direction, and a replenisher communication hole 3 is bored in the outer peripheral side wall so that the blue-green color of the pipe 3A is formed. It communicates with an external plating solution replenishment tank 15 through 3B.

A void, 2A, is provided in the center of each fan-shaped cylindrical tank 2,
When these are combined, a central cavity 7 is formed in the center of the cylindrical tank, and the central cavity 7 has a rotating shaft/
/ is housed, and a rotating shaft // is rotatably supported by an external drive via bearings (not shown) at the upper and lower ends of the cylindrical tank. This rotational shaft // is provided with an arm /, 2 in the radial direction above, a hanging tool for the object to be plated (not shown) is attached to the tip of this arm /2, and a grip part /2 is attached to the lower end thereof. q
It is configured so that the object to be plated can be suspended using the .

Further, the rotating shaft // is provided with appropriate means for raising and lowering during rotation, and furthermore, suitable means is provided for raising and lowering the cylindrical tank itself as required. For example, like in an elevator, a counterweight suitable for the weight of the cylindrical tank is connected with steel cables, allowing it to be lifted and lowered easily.

Next, the mode of use of this invention will be explained.

(1) First Example (Chrome Plating) Taking the example of chrome plating, if the rotation axis is clockwise in Figure q, 1.11. ■ Fill the tank with chrome plating solution, ■ Fill the tank with water, and place the arm of the rotating shaft // which has been raised in advance at the position of the take-out tray g, to be plated on the hanging tool /3 provided at the tip of 7. The object is attached, the rotary shaft is rotated intermittently 00 times to lower the object, the object to be plated is immersed in the plating tank I, and the object is moved through the solution for plating. Thereafter, this operation is repeated until the plated object is finally immersed in the washing tank V, and when the plated and washed object reaches the take-out pan G, the object to be plated is manually or automatically removed from the hanging tool and placed in the take-out pan. Place on top.

(2) Second Embodiment (Chrome plating) The first to V tanks are arranged as etching, chrome plating, chrome plating, and water washing.

(3) Nickel chrome plating on Fl example) The order of the plating is nickel plating solution, water, chrome plating solution, and water.

(4) First example (Chrome plating) After pre-treating the object to be plated with chrome,
Place 0 pieces and 7 pieces in a fan-shaped cylindrical tank, and plate each 7 pieces in about 1 second.

Note that the stepped part in the tank is tilted toward the center so that spilled liquid returns to the tank.

Note that the apparatus according to the present invention can perform high-speed plating.

As described above, according to the present invention, plating work can be performed in a small floor area, and is efficient even in a committee where land prices are high.
The plating tank is connected to an external replenisher tank so that the liquid can be refilled at will.
By making it easier to control the immersion time of the object to be plated, it has become possible to perform high-speed plating in a short period of time.

By making the plating tank side movable, the plating tank can be moved up and down, allowing the plating solution to be moved up and down for high-precision objects to be plated, and for objects that should not be shaken, while the objects remain stationary. This allows for good plating work.
