Definitions

  • the electroplated goods In the case of bulk electroplating of bulk goods, the electroplated goods must be held together during the electroplating process so that each individual part has electrical contact. On the other hand, the electroplated material should be spread out as far as possible so that the metal can be deposited on the largest possible surface of the goods and the most uniform current density possible on all parts. These two requirements must be met by the goods container.
  • a further essential prerequisite for achieving perfect metal coatings with a uniform layer thickness is the sufficient mixing of the electroplated material during the electroplating. This mixing of the electroplating material is usually brought about by rotating the goods container around a non-vertical axis, the individual parts being conveyed more or less upwards depending on the shape and wall friction and then rolling off or sliding down again.
  • the simplest container is the electroplating bell, a rotating pot that also serves as a bath container. Mixing of the electroplating material is achieved by rotating the bell, tilted against the vertical. Since the anode is hooked into the bell, the anode surface is usually too small in relation to the product surface even when using profiled special anodes. However, this then leads to low deposition rates and thus to an increase in the electroplating time and an increase in abrasion.
  • Galvanizing drums are also frequently used for mass electroplating, which, in contrast to the bell, only serve as a goods container and are arranged in a bath container.
  • the electroplating material is mixed by rotating the electroplating drum around a horizontal axis. Since the anodes are located outside the drum body, larger anode surfaces can be realized.
  • a perforation must be made in the jacket of the drum body for the passage of current between the anodes and the electroplated material.
  • the open cross-section of such a perforation available for the passage of current is, however, so small for reasons of strength and with regard to the size of the electroplating material that the passage of current is considerably impaired. However, this again leads to low deposition rates and thus to an increase in the electroplating time and an increase in abrasion.
  • DE-C 830 862 a device of the type mentioned is known, in which the goods carrying tray is provided with ribs in its interior, which favor a uniform distribution of the pourable goods on the bottom of the goods carrying tray.
  • the ribs take the pourable material with them when the goods tray rotates upwards, i.e. the degree of spreading on the floor of the product carrier is significantly increased by the ribs.
  • Both the product tray and a container for receiving the finished galvanized goods are pivoted about a common shaft mounted above the bath container in such a way that both containers can be brought into such a mutual position that the pourable material is emptied from the product carrier into the receiving container and this can be swiveled out of the electrolyte while the product carrier is being returned to the working position. The discharge of the finished galvanized material is therefore associated with considerable effort.
  • Aluminum deposited from aprotic, oxygen and water-free, organoaluminum electrolytes is characterized by its ductility, low pore density, corrosion resistance and anodizing ability. Since the entry of air through reaction with atmospheric oxygen and air humidity causes a considerable reduction in the conductivity and service life of these electrolytes, the electroplating must be carried out in an air-tight facility. In order that the entry of air can also be prevented when loading and unloading these air-tight devices, import and export locks are also required, which are designed as gas locks, as liquid locks or as combined gas-liquid locks. When mass-aluminizing using aprotic, oxygen-free and water-free, aluminum-organic electrolytes, there is also the problem of preventing air from entering the electrolyte as far as possible.
  • a device for the galvanic deposition of aluminum from oxygen and water-free, organoaluminum electrolytes in which a galyanizing drum rotatable about its horizontal axis in a gas-tight lockable bath container is arranged.
  • the galvanizing drum which is perforated, is surrounded by two anodes, which can be adjusted so that they form an opening for the bulk material to be emptied.
  • the electroplating drum is loaded by a transport device leading into the interior of the bath container via a lock, which ends above a closable opening of the electroplating drum, the opening and closing of the electroplating drum being carried out from the outside.
  • a discharge container designed as an export lock which is arranged below the bath container and communicates with it via a lockable, tubular connecting piece.
  • the invention has for its object to improve a device for the bulk electroplating of pourable material of the type mentioned so that the discharge of the finished galvanized material can be carried out quickly and with little effort.
  • the device should also be designed so that it can be operated with a justifiable additional effort in the absence of air and can be used for mass aluminization using aprotic, oxygen and water-free, organoaluminum electrolytes.
  • This object is achieved in that at least one slide is arranged for the discharge of the goods in the peripheral wall of the product carrier.
  • a slide provided in the peripheral wall of the device according to the invention can then be pulled up, for example, via an actuating element arranged on the outside, so that the finished galvanized material can be discharged particularly easily and quickly.
  • the product carrying tray With a suitable inclination of the product carrier, no further measures are required for the discharge of the goods.
  • the driver is formed by a plurality of ribs which protrude from the floor and extend to the upper edge of the goods carrying tray.
  • Such ribs can then be arranged in configurations which then form, for example, triangular, square, rectangular, circular, or honeycomb-shaped regions on the bottom of the goods carrier.
  • the goods are then spread out in each of these areas in a manner similar to that in a conventional goods carrying tray, i.e. the degree of spreading related to the floor area of the goods carrying tray is increased considerably.
  • the ribs can also form areas or zones which are connected to one another in the manner of a labyrinth.
  • the spread of the material can be further improved if the driver is formed by a plurality of ribs extending in the radial direction.
  • the product carrier can then be divided into several closed sectors by the ribs. This has the advantage that the material is then mixed separately in each sector and the degree of mixing is improved overall.
  • the driver can also be formed by a spiral path, such a spiral path to a large extent promoting the spreading and mixing of the material.
  • the web can be formed in a particularly simple manner by a profile introduced into the bottom of the goods carrier. With a profile that is sawtooth-shaped in cross-section, it is then possible, in particular, to further improve the transport of the goods into the higher regions of the goods carrying tray.
  • the bottom of the product carrier can also be perforated.
  • an additional anode can be arranged below the bottom and parallel to the bottom. As a result, the anode surface area is increased still further, so that particularly high deposition rates can be achieved.
  • the goods carrier shell consists of an electrically insulating material or is coated with an electrically insulating layer and that contact elements are arranged in the bottom of the goods carrier shell for cathodic contacting of the goods.
  • this prevents undesired metal deposition on the goods carrying tray, while on the other hand, the contact elements arranged under the material in the floor ensure a sufficiently uniform current consumption over the entire effective surface of the goods.
  • Metal deposits on the contact elements, for example in the form of button contacts, are at least largely removed again by the movement of the material and the abrasion associated therewith.
  • the angle of inclination of the axis of the goods carrier shell to the horizontal is approximately 30 to 38 °.
  • the angle of inclination of the axis of the goods carrier shell to the horizontal is adjustable, then With regard to the spreading and mixing, a particularly good adaptation to the requirements of the respective electroplating material is made possible.
  • the angle of inclination of the axis can then preferably be adjusted via the inclined position of the entire bath container. This takes into account the fact that when the axis is adjusted, the parallel orientation of the anode to the bottom of the product carrier is to be maintained.
  • the inclined position of the entire bath container can then be used to ensure a synchronous adjustment of the product carrier shell and anode in a particularly simple manner.
  • the bath container is expediently pivotably arranged on a frame.
  • the device according to the invention can be used with relatively little additional effort for mass aluminization using aprotic, oxygen and water-free, organoaluminum electrolytes. This is achieved in that the bath container can be closed gas-tight and that locks are provided for the introduction and discharge of the goods.
  • the bath container is then preferably provided with a lid arranged in the region of the anode, so that the anode is easily accessible when the lid is open and can be exchanged without problems if necessary.
  • FIG. 1 and 2 show a device for the mass aluminization of pourable material G in the partially broken top view or in longitudinal section.
  • an aprotic, oxygen- and water-free, aluminum-organic electrolyte In an arranged obliquely on a frame Ge and gas-tightly sealed with the aid of a lid D there is an aprotic, oxygen- and water-free, aluminum-organic electrolyte, the area above the electrolyte level Esp being covered with an inert gas, such as, for. B. nitrogen is applied.
  • the pourable material G to be aluminized which is, for example, screws, nuts, bolts, spacer bushings and the like, is introduced into the bath container Bb via an import lock Es only indicated in FIG. 2 and a subsequent inclined downpipe Fr. then falls into the sector S lying under the downpipe Fr, respectively, of a goods carrying tray, designated overall by W1 and completely immersed in the electrolyte.
  • the goods carrier W1 has the shape of an extremely flat circular cylinder, the bottom of which is designated B1 and the peripheral wall of which is Wa.
  • the goods carrying tray W1 is divided into six equal sectors S by a total of six radial ribs R arranged in uniform division, which - as already mentioned - are successively loaded with the pourable material G to be aluminized from above.
  • This successive loading of the individual sectors S is made possible in that the goods carrying tray W1 is rotated in the direction of the arrow U about its axis Ac which is inclined to the horizontal.
  • the corresponding drive shaft Aw of the goods carrying tray W1 is firmly connected to the base B1, is passed through the wall of the bath container Bb in a gas-tight and liquid-tight manner and is mounted in a bearing housing Lg attached to the outside of the wall of the bath container Bb.
  • the drive assigned to the drive shaft Aw is not shown in the drawing.
  • a plurality of contact elements K are arranged in the bottom B1 of the product support tray W1, which is made of enamelled steel sheet.
  • the material G spread out in one or two layers by the ribs R acting as a driver on the base B1 is contacted cathodically via the contacts K.
  • a disk-shaped anode A1 arranged at a short distance parallel to the floor B1 and thus also to the spread material G is only indicated schematically in FIG. 2.
  • the insulated fastening of this anode A1, consisting of pure aluminum and composed of several segments, in the bath container Bb does not appear from FIG. 2. However, it can be seen that the anode A1 can be easily replaced when the cover D is open.
  • the bath container Bb is arranged obliquely on a frame Ge, wherein the inclination can be changed by pivoting the entire bath container Bb.
  • the lower part of the bath container Bb is articulated to the frame Ge via an axis of rotation Da, while a pneumatically or hydraulically actuated adjusting cylinder Vz is articulated to the upper region of the bath container Bb via a first pivot point Dp1 and to the frame Ge via a second pivot point Dp2 is.
  • the inclination of the bath container Bb and thus also the angle of inclination of the axis Ac of the goods carrier W1 to the horizontal can be adjusted via the adjusting cylinder Vz.
  • the speed and the angle of inclination a can be matched to the material G to be aluminized in such a way that the spread of the material G shown in FIG. 1 results. It can be seen that there are zones in the central region of the sectors S which are not covered by the goods G in any position of the goods carrying tray W1. In order to prevent unwanted aluminum deposition, no contact elements K are arranged in these zones.
  • a device corresponding to the exemplary embodiment according to FIGS. 1 and 2 was also built on a model scale and tested together with a comparably designed device which has a galvanizing drum.
  • a comparably designed device which has a galvanizing drum.
  • higher deposition rates could be achieved by a factor of 2 to 3, whereby the layer thickness of the metal coatings was also even more uniform than when using the device equipped with a galvanizing drum.
  • Fig. 3 shows a variant in which the goods carrier shell with W2, the anode with A2 and the slider are again labeled Sch.
  • the drivers, which can again be ribs, are not shown.
  • a perforation P is made in the bottom B2 of the goods carrying tray W2, through which the electrolyte exchange can be further improved.
  • an additional anode ZA which, like the anode A2, is made of pure aluminum and is composed of several segments, is arranged at a distance parallel to the base B2 and at a distance from it.
  • the passage of current through the perforation P is restricted here, as in the case of a galvanizing drum, the arrangement of the additional anode ZA brings about a further increase in the deposition rates.
  • Multiple arrangements of goods trays W2 which can be rotated jointly are also conceivable, in which case the additional anode ZA then simultaneously serves as the main anode of the subsequent goods trays W2.
  • Fig. 4 shows a second variant, in which the goods tray is designated W3.
  • the bottom B3 of the goods carrying tray W3 is provided with a sawtooth-shaped profile in cross section, which forms a path Ba running in the form of a spiral.
  • This spiral path Ba forms a driver, which in turn forms a conveyor device through the rotation of the goods carrying tray W3, which transports the goods G from the lower area into the upper area of the goods carrying tray W3.
  • the material G then slides over the inclined flanks of the sawtooth-shaped profile, which results in very good mixing.
  • an inclination angle ⁇ and a rotational speed can be set for each good G, at which the good G is almost completely spread over the entire bottom surface of the goods carrying tray W3 when mixed thoroughly.
  • a single slide Sch is sufficient for the discharge of the fully galvanized material G, which is then opened in the lowest position of its orbit.
  • the angle of inclination a can then also be reduced to such an extent that the entire good G automatically falls out of the goods carrying tray W3.
