Description

Oct. 9, 1951 H. BABLIK GALVANIZING APPARATUS Filed April 1, 1949 Patented Oct. 9, 1951 UNITED GALVANIZIN G APPARATUS Heinz Bablik, Vienna, Austria, assignor to Brunner Verzinkerei Bruder Bablik, Vienna, Austria, a firm Application April 1, 1949, Serial No. 84,784 In Austria September 8, 1948 Claims. (Cl. 91-125) Devices for the hot-galvanising of simple articles such as metal plates, wires, tubes and the like have previously been proposed for automatically introducing the articles into the galvanising bath and removing them therefrom. Since the dipping of these articles takes place in their longitudinal direction the dipping process does not ofier any difiiculties. However, articles more particularly hollow bodies which are shaped in several directions and which have to be more or less turned about during the hot-galvanising in the zinc bath, have hitherto been galvanised only manually. This however, more particularly in the case of the galvanising of large hollow vessels, such as tubs and the like, requires large physical efforts on the part of the workmen and takes comparatively a long period of time, so that the output of the galvanised articles is small and the manual work entailed relatively heavy.
This invention relates to a device for hot-galvanising of articles shaped in several directions and more particularly of hollow articles, which owing to their complicated shape have to change their position several times during the passage through the galvanising bath, and the invention essentially consists in this that, in addition to the galvanising bath, conveying, holding and steering devices are provided which co-operate in such a manner that the hollow articles to be galvanised are subjected to changes in position required for the galvanising and are tilted during the removal from the bath in order to discharge the liquid zinc present in the hollow spaces.
In carrying the invention into effect according to one mode, the conveying device consists of a suspension train, each carriage of which carries tongs forming the holding device, the actuating arms of the tongs being provided with rollers which run on steering rails, the latter efiecting the change in position of the hollow articles during the galvanising and the emptying. In a preferred form of construction the rollers of the closing arms of the tongs act as counter-weights ensuring the closing position of their gripping arms. The steps of operation required for the galvanising may be carried out in a continuous manner by causing the conveying and the steering device to be led over the containers and the devices for the mordants, the washing, the flux treatment, the drying, the zinc bath and if required over the devices for the subsequent treatment of the hollow articles.
The accompanying drawings illustrate diagrammatically and by way of example one mode of carrying the invention into efiect in connection with the galvanising of pails.
Figure 1 is a side view of the device wherein the galvanising pan is shown in longitudinal section, and
Figure 2 is a cross section along the line II-II in Figure 1.
Referring to the drawings, 2 is a galvanising tank or pan containing the zinc bath I over which there is provided a guiding track constituted by two rails 3 and 4' arranged in a vertical plane, the lower rail 3 serving to support the rollers 5 of small carriages 6, whilst the upper rail 4 serves as a guide for the said rollers. The rails 3 and 4 are inclined downwardly over the ends of the tank or pan 2, so that the carriages 6, which are interconnected by a driving means or pulling member I, approach the level of the zinc in the bath during the pulling of the member I in the direction of the arrow in Figure 1, being then pulled for a certain portion parallel to it, and thereupon again led upwards. On each carriage there is provided a carrying member 8 pivoted at 9, an articulating bolt I0 being provided at its lower free end for the arms of holding means in the shape of holding tongs, the latter being arranged so as to be capable of being rocked transversely to the direction of movement of the carriages. Closing arms or projections II, II of the tongs are provided at their free ends with rollers I2, I2 which, acting as biasing means counter-weights, force the holding arms or gripping elements I3, I3 rigidly connected with said closing arms II, II into the closing position. The roller I2, I2 co-operate within the range of the pan 2 with the steering rails I4, I4, which are fixed above'it and which are arranged parallel to the direction of movement of the carriages 6. The pails I5 are suspended between the holding arms I3, I3, being held firmly owing to the weight of the rollers I2, I2. When the carriages are driven in the direction of the arrow (Figure 1) by means of the pulling member I, the pails are caused to be introduced into the zinc bath I, as can be seen from the drawings. Before the complete immersion, the roller I2 abuts against the steering rail I4, so that the arm I I is pressed downwards and the pail I5, after complete escape of the air, is completely immersed into the bath, and at the same time it is moved transversely to the direction of movement to the right (Figure 2) where upon, owing to the co-operation of the waveshaped steering rails I4, I4 with the rollers I2, I2, the pail is rocked to and fro during the forward movement in the zinc bath; now the pail is lifted out of the zinc bath and when reaching the last wave crest of the rail I4 is so tilted that the zinc taken along within the bottom border of the pail can flow away, whilst the next following wave through of the rail H causes any possible trace of zinc that may be present in the hollow space of the pail to be thrown off. The carriages 6 are carried along an endles track under which lie the containers or the devices for the mordants, the washing, the flux treatment, the drying, the zinc bath, and if required the devices for the subsequent treatment of the articles to be galvanised. In the case of the containers intended for the mordants, the washing and the flux treatment, similar steering surfaces l4, M are provided for the dipping of the pails IS.
The device according to the invention, which may be suitably constructed for all kinds of articles shaped in difierent directions, enables the galvanising process to be substantially accelerated since several articles can be simultaneously treated in the galvanising pan, whereby a substantial reduction in expenditure is effected from a thermo-economical point of view as compared with the manual galvanising.
