Definitions

  • the present invention refers to a wire drawing machine able to reduce gradually the section of a metallic wire.
  • the present invention refers to a multiple-step wire drawing machine preferably of the dumping hose type.
  • Each station or wire drawing group is provided of pulling means comprising an alternate current electric motor.
  • Said pulling means are connected between a transmission and a reduction gear to a capstan or rotatable drum on which is wrapped said metallic wire.
  • Said friction forces permit to force the passage of said metallic wire through a tool determining a reduction of section by means of a plastic deformation of said metallic wire.
  • each wire drawing station commonly comprises a trapezoidal or toothed belt transmission, and a toothed reduction gear.
  • Each electric motor is connected to a correspondent belt transmission, in such a way to have a first reduction of the number of revolutions per minute.
  • a disadvantage of the known wire drawing machine is that show an elevated numbers of components.
  • Another disadvantage is that having many moving elements these during the time are subjected to the wear, and consequently they need a control and periodical service for maintaining a correct working of the wire drawing machine.
  • a further disadvantage is that lots of elements have to be assembled and disassembled, determining high costs and time for the service and also a reduction of the productivity of the wire drawing machine.
  • Purpose of the present invention is that to realize a wire drawing machine that avoid the necessity a transmission and also a reduction gear in each wire drawing station of said wire drawing machine.
  • Another purpose is that to realize a wire drawing machine having a reduced number of components.
  • Another purpose is that to realize a wire drawing machine having reduced time and costs of service.
  • Still another purpose is that to have a wire drawing machine having low noisy.
  • Said wire drawing machine 10 comprises a plurality of wire drawing stations 20 which, starting from a first station toward the following stations 20, are able to gradually reduce a section of said metallic wire 90.
  • said plurality of stations 20 are connected in series between them and besides are connected to a fixed structure 12 of which said wire drawing machine 10 is provided.
  • each station 20 comprises a capstan or rotatable drum 22 on which is wrapped said metallic wire 90, a tool 25 which in particular a die or a draw box, and pulling means connected to said rotatable drum 22 which are able to rotate said rotatable drum 22 forcing consequently the passage of said metallic wire 90 through said tool 25 in such a way to reduce said section of said metallic wire 90.
  • said wire drawing machine10 is a multi-step wire drawing machine 10 preferably of the dumping hose type.
  • Said pulling means comprise an alternate current electric motor 30, in particular asynchronous or with permanent magnet, and preferably powered by a correspondent inverter.

  • said electric motor 30 comprises first liquid cooling means 40 integrated internally to the same.
  • this determines an high cooling efficiency of said electric motor 30 respect to an air cooling.
  • this determines also a notably reduction of the noise emissions also to a short distance.
  • each station 20 comprises second liquid cooling means 50 able to cool said rotatable drum 22 and said metallic wire 90.
  • said second liquid cooling means 50 comprises at least a liquid distributor 52 which is housed internally to said rotatable drum 22 for cooling from the inside the same and also said metallic wire 90.
  • each station 20 comprises an hollow shaft 27 which connect directly said electric motor 30 to said rotatable drum 22.
  • this also permit to feed internally to said rotatable drum 22 a cooling liquid in such a way to obtain a better cooling of said metallic wire 90 during the plastic deformation.
  • said second liquid cooling means 50 of each station 20 includes a feeding conduit 55 of a cooling liquid which is inserted internally to said hollow shaft 27 and which is preferably connected to said at least a liquid distributor 52.
  • said first liquid cooling means 40 of said electric motor 30 comprises at least a liquid cooling circuit 42 which is integrated in the external structure 34 of said electric motor 30.
  • said pulling means comprise coupling means able to constrain and to transmit a rotating movement of said electric motor 30 directly to said rotatable drum 22.
  • said coupling means are integrated in the external structure 34 of said electric motor 30 and in an internal portion of said rotatable drum 22.
  • said coupling means are releasable coupling means.
  • said coupling means comprises a bayonet coupling.
  • said electric motor 30 comprises a stator 33 fixed to said external structure 34, and a rotor 31 constrained or fixed to a fixed structure 12 of said wire drawing machine 10.
  • each station 20 comprises fixing means able to constrain and to make integral said external structure 34 of said electric motor 30 to said rotatable drum 22.
  • said coupling means are integrated with said fixing means.
  • said external structure 34 is fitted together or however made integral internally to said rotatable drum 22.
  • said electric motor 30 is integrated with said rotatable drum 22.
  • said electric motor 30 is at least partially inserted in the inside of said rotatable drum 22.
  • said electric motor 30 is totally inserted in the inside of said rotatable drum 22.
  • said external structure 34 of said electric motor 30 is integrated with an internal portion of said rotatable drum 22.
  • said first liquid cooling means 40 are at least partially integrated within said external structure 34 of said electric motor 30 and are able to cool at the same time said electric motor 30 and said rotatable drum 22.
