Definitions

  • the present invention relates to a roller such as those used in spinning lathes, in which a chuck presses a disc-shaped metal sheet against a rotary mold and on which said sheet acts at least one roller mounted on a carriage with a programmed automated motion, so that said roller deforms the sheet against the rotary mold so that it adopts the shape of the latter.
  • the object of the invention is to provide a roller with great structural simplicity and simple assembly, with the ensuing benefits in the costs of fabrication and assembly and disassembly of the rollers.
  • a power unit supplies a rotational motion to a mold shaped as a solid of revolution, so that on a single lathe may be implanted molds with different generatrices, depending on the desired shape of the sheet after spinning.
  • the sheet is initially flat and circular, and rests on its centre and axially on the mold, to which it is secured by a chuck which allows it to rotate freely when driven by the mold.
  • a roller which is rotationally mounted on a roller-bearing carriage, so that the roller follows the path of the mold generatrix with automated motions which correspond to a control program of said carriage.
  • rollers consist of two parts, the roller itself and a cover which is attached to it by bolts, so that these elements define an axial housing for a pair of bearings and the corresponding spacer placed between them.
  • These bearings are obviously meant to allow a free rotation of the rollers about their axis, with the cover closing the roller housing after such mechanisms are installed inside it.
  • roller for spinning lathes disclosed solves the above drawbacks in a fully satisfactory manner, providing a solution with a simple structure and assembly, with the ensuing reduction in costs.
  • the roller consists of a single part, not requiring a cover nor any additional accessories for mounting the bearings, which is the only machined part of the assembly and which in the inevitable axial orifice for coupling to the shaft incorporates an intermediate narrowing which acts as a spacer for the conventional bearings, so that these are mounted on opposite sides of the roller, with the outer bearing axially retained by the conventional flange at the end of the aforementioned shaft, while the other bearing is also retained axially against the common spacer by a simple washer which remains in working position when said shaft is coupled and attached to the corresponding roller-bearing carriage.
  • FIG 1 shows a schematic representation of a conventional spinning lathe which, as is conventional, comprises a rotary mold (1) driven by a power unit (2), which rotary mold in this case has a cambered hemispherical configuration but which may adopt any other shape depending on that intended for the sheet (3) to be spun, and which mold (1) is placed axially opposite a chick (4) which is aided by the corresponding driving mechanism (5), so that said chuck (4) can push the sheet (3) against mold (1) on its centre, keeping it perfectly held in place while the roller (6) acts, which mounted on a roller-bearing carriage (7) follows the generatrix line of the mold (1), for which purpose said roller-bearing carriage is provided with automated motion means and is duly programmed.
  • said roller (6) consists of a roller (6) itself, in a single part, with the classical rounded, operational perimetral edge (8) and with the also classical axial orifice (9) for passage of shaft (10) for coupling to the carriage (7), with a pair of bearings (11-11') interposed; also in accordance with the invention said roller (6) itself, at its mid area of its axial orifice (9), incorporates a narrowing (12), that is, an inner annular ribbing which acts as a spacer for bearings (11-11'), as shown clearly in figure 2.
  • the outer bearing (11) is retained against spacer (12) by flange (13) at the free end of shaft (10), while the internal bearing (11') is in turn retained axially against spacer (12) by a washer (14), which when the roller assembly is mounted on carriage (7) presses sideways on the arm (15) of said carriage, when the latter is finally secured by bolt (16).
