DE1801128A1 - Continuous pass-through electroplating system for long shafts or profiles - Google Patents

Description

Description D es! Ju z Walber, er Continuous pass-through electroplating line + It is known that for long waves, if a chrome or other electroplated layer without overlap, fixed, deep bands are required, depending on their length to be used. In the case of multilayer chrome plating or electroplating, there is one correspondingly large number of bathrooms required. Even with partial chrome plating or electroplating are appropriate according to their distance from the shaft end deep baths required.

The object of the invention is to eliminate the complex and expensive ones previously required Replace plants with a plant in which the treatment in a continuous process is possible. In particular, waves or profiles of any length should a) not in stationary, but in mobile systems with a horizontal position or can be electroplated.

The pretreatment, main and post-treatment baths are located in this mobile system.

The chrome-plated or electroplated shaft is through the end walls of the individual compartments, which are provided with a special seal, continuously passed through.

If, for certain reasons, the shaft should remain stationary, the System mounted on wheels continuously guided along the shaft. With this Attachment can also be chrome-plated or galvanized at any point on the shaft will.

b) In a stationary system, the waves or profiles are arbitrary Length vertically passed continuously through the system.

The system is essentially the same as the system described under a).

For this embodiment, the shaft is lowered into a borehole corresponding depth required. With this system, any point be chrome-plated or galvanized on the wavelength.

Fig. II shows an exemplary embodiment of the concept of the invention, namely Fig. 1 in view, Fig. 2 in plan view.

On a parallel track (1) there is mounted on several axles, a container that can be moved. This container is divided into individual compartments by partition walls (3, 4, 5, 6) for the pretreatment solutions, Electroplating solutions and aftertreatment solutions.

The two end walls (7u.8) and the walls of the compartments (3,4,5,6) are according to the diameter of the shafts or profiles to be galvanized, as shown in Fig. III shows pierced.

In Fig. III the sealing system is drawn and shows a Rinsing chamber (9) which is connected to a hot water pipe. This chamber is by means of seals of known design (13), liquid-tight on both sides, so completed that the waves or profiles (14) can be moved.

With the mobile container (2) is through several pumping devices connected to a reserve tank of the same subdivision, which is not shown here.

A suction frame (10) is located on the mobile container (2).

The anodes (11) in Fig. II and II in the electroplating compartment are in two parts executed and arranged centered on the sealing system.

The shaft or the profile to be galvanized is placed on mobile supports (12), which run in the same track (1), put on, one or two such mobile supports serve as direct current transmission. (Trolley of known execution and) Before the introduction into the container compartments expediently an insertion piece with the same diameter or profile to the screwed on the left or right face of the shaft or profile to be refined.

Fig. II shows in elevation and partially in section the vertical, stationary one Plant for continuous through-flow electroplating of shafts and profiles; above a borehole in the ground, drilled deep (15) according to the shaft length a vertically arranged, round or angular bath group (16,17,18,19,20).

This bath group stands on a frame so that the individual bath containers can be fitted centered on one another.

The assemblies consist - seen from top to bottom - of pretreatment (1 9u02o), electroplating (1 7u. 18) and post-treatment compartments (16). Above the pre-treatment compartment (20) there is a centering (21) for inserting the shafts (14) into the Apparatus.

The cathodic power supply (22) is arranged above it.

The anodes are arranged in the same way as the horizontal system (11).

The sealing system (13) is also analogous to the horizontal system executed.

The fixed transfer and overflow device (23-25) is for each Compartment provided.

At the lower part of the vertically installed system there is a Place (26), where the shafts can be measured for dimensional accuracy.

A centering (27) is located above the borehole (15), matching it for the respective shaft diameter or profile.

Before being inserted into the apparatus, the shafts are through on both sides To extend the screwing on of the corresponding shaft or profile ends.
