Apparatus for mechanically removing the scale from the peripheral surface of a hot rolled wire material

Claim 1

An apparatus for removing the scale produced on the peripheral surface of a wire material during the hot rollinG thereof, comprising: at least three brushing wire wheels disposed in angularly spaced relationship with each other for brushing contact with the peripheral surface of the wire material and in spaced relation with each other in the direction of wire advancement; each of said wire wheels being disposed with its plane of rotation inclined at an angle with respect to the run of the wire material and arranged such that the wire wheel is in contact with the peripheral surface of the wire material substantially at the central point of the width of the common peripheral surface of the wire wheel and that the radius of the wire wheel included in a transverse plane and passing through the point of contact between the wire wheel and the wire material is in alignment with the radius of the wire material passing through said point of contact, said transverse plane extending radially through said point of contact; electric motors for rotating said wire wheels, each having an output shaft on which one of said wire wheels is rigidly mounted for rotation thereby; rod members for supporting the respective wire wheels in the above-stated positions, said rod members extending substantially parallel to the run of said wire material, and each of said rod members having an inner end rigidly secured to one of said electric motors in an outer end portion extending through a machine frame of said apparatus, said outer end portion being pivotally mounted on said machine frame and having an arm rigidly connected to the outer end of said outer end portion and extending substantially parallel with said machine frame; means for adjusting the radial position of said wire wheels with respect to the axis of the wire material to thereby adjust the pressure at which the wire wheels are in brushing contact with the wire material comprising screw members each being threadably mounted on said machine frame and operatively connected to said arm for pivotally moving said arm to thereby adjust the angular position of the corresponding rod member with respect to the run of said wire material; a plurality of sheaves disposed upstream of said brushing wire wheels and arranged so as to define a meandering path of travel along which the wire material is caused to move, said path of travel being curved in at least two radial directions of said wire material for subjecting the wire material to repeated bending in such directions so that loose scale particles are removed at the point upstream of said brushing wire wheels; and each of said wire wheels comprising a plurality of disc-like members arranged substantially in laminated relationship with each other, the disc-like members with the exception of the opposite outer ones thereof being formed therein with a plurality of circumferentially spaced axial apertures adjacent the outer peripheral edges thereof, a plurality of substantially U-shaped bundles of wire rods each having its intermediate portion of the U-shape extending through one of said axial apertures, the leg portions of each bundle extending radially outwardly through the gap between each adjacent pair of said disc-like members and beyond the outer peripheral edges thereof and terminating in said common peripheral surface of the wire wheel, means for firmly fastening said disc-like members together so that said wire bundles are firmly held in radially outwardly extending positions between adjacent disclike members, and a central through-hole formed in the assembly of said disc-like members for receiving the output shaft of one of said electric motors.

Claim 2

An apparatus for removing the scale produced on the peripheral surface of a wire material during the hot rollinG thereof, comprising: at least three brushing wire wheels disposed in angularly spaced relationship with each other for brushing contact with the peripheral surface of the wire material and in spaced relation with each other in the direction of wire advancement; each of said wire wheels being disposed with its plane of rotation inclined at an angle with respect to the run of the wire material and arranged such that the wire wheel is in contact with the peripheral surface of the wire material substantially at the central point of the width of the common peripheral surface of the wire wheel and that the radius of the wire wheel included in a transverse plane and passing through the point of contact between the wire wheel and the wire material is in alignment with the radius of the wire material passing through said point of contact, said transverse plane extending radially through said point of contact; electric motors for rotating said wire wheels, each having an output shaft on which one of said wire wheels is rigidly mounted for rotation thereby; rod members for supporting the respective wire wheels in the above-stated positions, said rod members extending substantially parallel to the run of said wire material, and each of said rod members having an inner end rigidly secured to one of said electric motors in an outer end portion extending through a machine frame of said apparatus, said outer end portion being pivotally mounted on said machine frame and having an arm rigidly connected to the outer end of said outer end portion and extending substantially parallel with said machine frame; means for adjusting the radial position of said wire wheels with respect to the axis of the wire material to thereby adjust the pressure at which the wire wheels are in brushing contact with the wire material comprising screw members each being threadably mounted on said machine frame and operatively connected to said arm for pivotally moving said arm to thereby adjust the angular position of the corresponding rod member with respect to the run of said wire material; a plurality of sheaves disposed upstream of said brushing wire wheels and arranged so as to define a meandering path of travel along which the wire material is caused to move, said path of travel being curved in at least two radial directions of said wire material for subjecting the wire material to repeated bending in such directions so that loose scale particles are removed at the point upstream of said brushing wire wheels; and each of said wire wheels comprising a plurality of disc-like members arranged substantially in laminated relationship with each other, the disc-like members with the exception of the opposite outer ones thereof being formed therein with a plurality of circumferentially spaced axial apertures adjacent the outer peripheral edges thereof, a plurality of substantially U-shaped bundles of wire rods each having its intermediate portion of the U-shape extending through one of said axial apertures, the leg portions of each bundle extending radially outwardly through the gap between each adjacent pair of said disc-like members and beyond the outer peripheral edges thereof and terminating in said common peripheral surface of the wire wheel, means for firmly fastening said disc-like members together so that said wire bundles are firmly held in radially outwardly extending positions between adjacent disclike members, and a central through-hole formed in the assembly of said disc-like members for receiving the output shaft of one of said electric motors.
