PICKLING APPARATUS FOR DRAWN WIRES.
Specification of Letters Patent.
Patented War. it, 19116.
Application filed February 6, 1914. Serial No. 816.954.
To all whom it I)l(l]/ concern:
Be it known that l. \YiLincLu Firms, a subject of the Emperor of (lermany, and resident of 5.") llagenstrasse, Dortmund, (iermany. have invented a certain new and useful Pickling Apparatus for Drawn Wives; of which the followhu; is a specitication.
This invention relates to a new process for the subsequent treatment of wire after it has been drawn or rolled, and also to an apparatus for carrying out this process.
A constructional example of the app-era tus is illustrated in the accompanying draw ing, wherein Figure 1 shows a side elevation of the ap paratus, Fig. 2 shows a plan, Fig. 3 shows in cross section the drum employed, and Fig. 4 shows the method of guiding the wire in the water trough.
According to the invention, the wire, after it has been drawn or rolled. and before it is wound up, is passed through a receptacle or brush filled with chalk or a similar substance forming a chalk bath, so that the surface of the wire is covered with a thin layer-of chalk or the like. This facilitates the access of the, hot gases to the surface of the wire in the annealing operation, as it prevents the metallic surfaces from actually contracting with one another. The wire is now wound on drums on (Fig. 1) and annealed while on these drums by placing a receptacle, in which a number of drums are superposed, into an annealing furnace. The drums a as shown in Fig. 3, are hollow and are of a somewhat conical form, so that the wire, whenthe drums are placed on end, can easily be unwound over the edge a on the smaller side, and for annealing purposes the combustible (charcoal and the like) can also be placed in the interior of the drums.
After annealing and cooling a large numher of the drums on which the wire has been wound are placed intothe device shown in the drawing. being firstly placed into the bath 1). This bath contains a suitable acid or steeping liquor which removes from the surface of the wire any annealing scale and the like which may have been produced during the previous treatments. The presence of the layer of chalk supports and expedites this action. as it allows the acid to all the superficial elements of the wires as it did to the heat or annealing gases when annealing. This rapid and free access is permitted as the separate windings of the wire on the drum are a certain. distance apart. in consequence of the interposed layers of chalk. and there fore do not directly contact w th one an other, and because the chalk. in view of its hygroscopic nature. rapidly absorbs the acid and ell'm-tively conducts it to the. various parts of the surface of'the wire.
The drums lying in the bath I have their smaller sides turned upward. and the wire o is unwound from them. in an upward direction. Above the acid bath 7) is disposed a shallow water trough 1' through which water flows in the direction of the arrow (Fig. At the outlet end the walls (Z of the trough are nearer together than at the inlet end. as at certain intervals they are provided with lateral indentations 0. These indentations serve for the admission of the wires a from the drums a into the water trough and at the same time to hold the wires a certain distance apart so that they will not contact with one another. Vv'here the wires change their direction at the trough indentations c. that is to say. where they pass from a vertical into a horizontal direction of movement. guiding sockets l and guide rollers m are mounted in the walls of the trough c.
The wires 0 pass through the trough 0 in an opposite direction to that of the 'ater, and at the upper end of the trough pass nnderneath one or more bridges (1'. Here the acid and any remaining chalk is rinsed from them by the water. After leaving the trough c the wires pass into a receptacle 7 filled with sand. which latter absorbs any water adhering to the wires and to a certain extent dries them. The wires then pass into a bath containing an alkaline solution. Suitably distributed shafts 71-. having guide rollers loosely mounted thereon, submerge the: wires in the alkaline solution and control its movement therein. The alkaline solution is adapted to clean completely the surface of the wires. especially to remove any adhering acid. and according to the soiution used to produce other results. for example. to polish. smooth. oxidize or otherwise act upon the superficial structure. The first alkaline bath g, may he succeeded by a second hath. indicated in the drawings by y. or by a number of such baths. From the alkaline baths the wires again pass through a receptacle f containing sand, in order to he dried,'and from here they passbver a; heated hearth k where they are completely dried. After leaving the hearth lo the wire is wound in the known manner, by a winding machine, int0, ci1sor bobbins and can then be transported ready for use. The winding up of the wires forms suitable means for moving the wires through the device herei'nbeforedescribedJ Only the shafts h,
t, are driven from a source of power advantageously derived from the winding machine, so that they will rotate according to the movement of the wire and therefore need not be rotated by the wires a which are mostly very thin. In this manner a breakage of the wire during its subsequent treatment after it has been drawn or rolled is obviated as far as possible.
certain intervals, a drying device, a bath of an alkaline solution, and a second drying device. Y 2. A device for the subsequent treatment of drawn or rolled wires, comprising an acid moving the wires in an opposite direction to the flow of water in the water trough.
3. A device for the subsequent treatment of drawn.or rolled wires, comprising an acid bath, drums insaid bath on which the wires are wound, said drums being of tapered form to permit of the easy unwinding of the wires therefrom, a water trough, means for guiding. the wires into the water trough, a bridge, said bridge collecting together the wires and retaining them a certain distance apart, a drying device, abath of an alkaline solution, and second drying device, and means for moving the wires through the device.
In witness whereof, I hereunto signed my name this 10th day of Jan. 1914 in the presence of two subscribing witnesses. W ILHELM FRESE.
