Definitions

  • This invention concerns improvements to the heads of coil-forming machines, and also the heads of coil-forming machines which adopt said improvements.
  • the invention concerns improvements envisaged for coil-forming heads able to generate curved spirals of wire rod having a substantially constant pitch and diameter, the process starting with substantially straight continuous . wire rod.
  • Such machine are mainly employed to form coils of wire rods coming from the rolling process.
  • Said wire rods come with a straight movement and pre-set. speed into a rotating guide so shaped as to induce the spiral formation required.
  • Said rotating heads consist substantially of a spindle cooperating with a shaped guide.
  • the spindle is made to revolve by a motor means which is advantageously an electric motor and which is located at the side of, or else at a given distance- from, the coil-forming head and can cooperate with said head- through suitable means that transmit the motion.
  • a motor means which is advantageously an electric motor and which is located at the side of, or else at a given distance- from, the coil-forming head and can cooperate with said head- through suitable means that transmit the motion.
  • said means can be orthogonal or cylindri - cal gear wheels which cooperate with a motor disposed ortho-. gonally or parallel to the axis of the spindle, or else said. means can be gear wheels of another type or other mechanical. means suitable for the purpose.
  • the motor means have their armature solidly fixed to the spindle and located substantially coaxial with and around said spindle.
  • Our invention therefore consists of improvements to the. heads of coil-forming machines comprising rotating guide means and fixed structure means which support said rotating guide means, said improvements being characterized by the fact that the rotating guide means act substantially as the shaft of . the motor means which drives the coil-forming heads.
  • This invention is also pursued by the heads of coil- . forming machines which include rotating guide means and fixed structure means that support said rotating guide means, said heads being characterized by the fact that the rotating guide means act substantially as the shaft of the motor means which drives the coil-forming heads.
  • the coil-forming head shown 10 comprises. a fixed supporting structure II which consists substantially. of a frame 12 within which a rotating guide 53 is installed . at least partially.
  • Said rotating guide 53 comprises a spindle 14 supported. by bearings 15-115 which are suitably sustained (13-113) and. located axially at the frontal ends of said frame 12.
  • Suitable flange means I6 which cooperate with and rest . against the supports I3 keep the bearings 15 in their working position in relation to the frame 12.
  • Spacer means 17-117 cooperate in a coordinated manner with, and are axially located on, the spindle I4 and keep said bearings 15-115 in position with the help of opposed contrast means 18-118 respectively in coordinated cooperation with said supports 13-113 and said flange means 16.
  • Possible circumferential ring-wise-closure means I9 may. be comprised on the front discharge part of the coil-forming. head 10.
  • Said inlet mouth 2I is followed by a substantially straight conduit 22, the walls of which 23 can possibly contain,. at least partially, some interspaces or ducts 24 for a cooling fluid such as water, for instance.
  • Forced air may perhaps be introduced into the conduit 22 through one or more nozzles 25 machined in said guide means 20 near said inlet mouth 21.
  • the forced air can be channelled into the spindle 14 by means of through slits or holes 26 which may possibly be comprised in suitable clamping means 27 located inside said spindle 14.
  • Said clamping means 27 can grip and hold the inlet end . of specially shaped guide means 28, which are conformed in our example like a shaped tubular conduit.
  • the wire rod or wire having a substantially straight . form is inserted at a pre-set speed into the mouth piece 29 . axially aligned with the conduit 22 and said means 28.
  • the wire rod is curved progressively and is rotated at the same time with a pre-set. angular speed owing to the rotation of the spindle I4 so that it takes up the desired spiral form.
  • the means 28 are fastened to the spindle 14 by the clamp- .ing means 27, as said earlier, so as to be set in rotation, . and their outlet end 32 is clamped by particular rotating and supporting means 33 solidly fixed to the spindle itself 14.
  • rotating and supporting means 33 are connected frontally to . the end part of the spindle I4 by a flange element 36 and appropriate locking bolts 34.
  • connection with bolts can be re-. placed with another type of connection.
  • the rotating and supporting means 33 comprise also at their unconnected end a circumferential element 35 of the type, for instance, such as a wheel or disk onto which said outlet. end 32 is clamped.
  • Said element 35 and the flange element 36 are connected. axially by a lengthwise structure 37 which bears radial ele-. ments 38 to support the intermediate part of the guide means. 28.
  • the figures also show a balancing structure 39, which in our example consists of a tubular conduit the same as the conduit forming the shaped guide 28 and which is located diame-. trically in symmetry relatively to said guide 28.
  • the spindle 14 acts substantially as a rotation shaft for the motor means 40, which in our example is an electric motor coooperating with the coil-. forming head 10.
  • said motor means which are of a direct . current type in the example shown in Fig.I, are supported on. a suitable carrying and alignment structure 4I and are anchored with the yoke 42 of the armature 43 outwardly to the spindle 14.
  • FIG. I shows the parts constituting said electric motor 40 and comprising substantially the stator 44, . which consists of the yoke or body 45 and poles 46 cooperat-. ing with the stator windings 30, and the armature 43, which . consists of the core of armature laminations 47 and the armature winding 48 with the relatirtre connections 49 to the com-. mutator 50, whereby some sliding contacts or brushes 51 are . included which are solidly fixed to the stationary part of . the motor 40 and feed the supply current to said armature winding 50.
  • Cooling of the motor means 40 is performed with known .
  • means which in our example consist of fans or other means for forced convection of cooling liquid 52 (Fig.2) which cause air or cooling liquid to circulate within the coil-forming . head 10 in such a way that the circulation laps or comes into contact with the parts of the electric motor 40 and possibly. also of the spindle 14 which have to be cooled.
