DE925342C - Device for removing the scale skin, possibly already broken by a pre-descaling, from goods to be descaled, e.g. B. Wire - Google Patents

Description

Device for removing the, if necessary, by a Vorentzu_ Change of already broken scale skin of goods to be descaled, e.g. B. Wire To Mechanical descaling or rust removal from wire or the like are known constructions, in which the wire is passed through a housing, where by compressed air or centrifugal force Abrasive particles, e.g. B. Ouarzsand or steel gravel, by means of sandblasting, showers or centrifugal wheels are thrown against its surface. Also tubular Housings have been suggested for guiding the sandblasting. Through this But centrifugal devices are such -constructions in the acquisition and in the Relatively expensive to operate.

Furthermore, constructions are known in which the to be treated Wire pulled horizontally between material with angular and sharp surfaces will. However, these devices have the disadvantage that the wire from the surrounding it Material soon works out solid tracks and therefore no attack surfaces in a short time finds more who can edit it.

The disadvantages of working out the webs in the angular Material occur, are avoided according to the invention that the columnar -Housing arranged with a vertical longitudinal axis and filled with the abrasive is and the good is carried out in the longitudinal direction.

The entrained by the wire or the like against their direction of fall Abrasive particles have an effect on the one hand through their fall, on the other hand through their mutual Pushing and forcing the cleaning of the wire. At the same time one finds permanent Relocation of the scouring material statu. so that no paths arise in this, through which the wire runs without being processed by the abrasive particles.

Compared to the first-mentioned constructions according to the invention The device has the advantage that it does not require any additional aids Throw abrasive on the material to be descaled.

It is advantageous if the housing is a pipe. Besides, it is It is advisable to provide guide rollers that are known per se, which are to be descaled Guide it well through the housing.

There is a particularly suitable embodiment of the new construction in that the housing has a closable longitudinal slot for introducing the goods owns.

Finally, it has proven to be useful that the columnar Housing can be folded around a horizontal axis and locked in its end positions as well as with a closable longitudinal slot for inserting the wire or the like is.

In the drawing, an exemplary embodiment is shown in FIG new construction.

From a brakable supply reel a is to be derusted or To be descaled wire or the like. By a device b for breaking the on his Surface sitting crust and from there via a swiveling pulley c passed through a vertical tube e that can be tilted about a horizontal axis d. This has a coverable by a flap f longitudinal slot g and is with a powdery to coarse-grained filling compound i made of sharp-edged hard elements, z ,, B: - steel shot, filled.

Should a wire m -in 'the longitudinal slot g of the tube e- be inserted,. this is then tilted into the horizontal position and held there by a spring lock s which interacts with a stop t on the tube e. The flap f can now be opened and closed again after inserting the wire. The tube e is then tilted back into the vertical position. There it rests against a resilient stop on the support frame and is held in place by a spring lock u which is also lifted out. -. . The wire m or the like is withdrawn from the reel ca at an appropriate speed, the crust on its surface is broken in the device b and can already partially fall off when it is deflected around the rail c. During its subsequent passage through the vertical tube e, its entire surface is intensively processed by the: sharp-edged filling compound elements, which constantly regroup themselves through their own upward movement, in order to immediately fall back into another position and fall back down again; attack the wire surface. .

At the top of the tube e a second deflection roller k is provided, from which the material to be treated m runs through a lubrication box n into a drawing nozzle and finally to a drawing drum.

PATENT CLAIMS: I. Device for removing the possibly by a pre-descaling of already broken scale skin of goods to be descaled, e.g. B. wire, in which the good is pulled through a housing and there the action of a powdery or coarse-grained, hard abrasives, e.g. B. steel shot exposed is, characterized in that the column-shaped housing (e) with a vertical longitudinal axis arranged and filled with the abrasive (i) and the good (-in) in its Is carried out lengthways. 2. Device according to claim I, characterized in that that the housing (e) is a tube. 3. Device according to claims I and 2, characterized dutch known per se that the product (m) to be descaled passes through the housing (e) Guide rollers (c, k). 4. Device according to claims I and 2, characterized in that that the housing (e) has a longitudinal slot (g) that can be sealed in to insert the goods (m) owns. 5. Device according to claims I, 2., 3 or 4, characterized in that the housing (e) can be folded around a horizontal axis (d) and can be locked in its end positions.
