Definitions

  • the present invention relates to a wire cooling device for a wire drawing machine according to the preamble of claim 1.
  • wire cooling devices which are basically of two kinds: indirect cooling devices and direct cooling devices.
  • Indirect cooling consists of cooling by circulation of liquid the tools in contact with the wire, that is to say the die and the traction capstan.
  • the residence time of an elementary slice of wire in the die being extremely short, this cooling is very limited.
  • the capstan allows a large number of turns to be stored, thus increasing the contact surface between the hot wire and the cooled capstan. This cooling is therefore more efficient but is limited by its principle of heat exchange on the one hand, and by the purely linear contact between the round wire and the cylindrical capstan on the other hand.
  • Another method consists in spraying the cooling liquid from the outside directly onto the turns of wire accumulated on the capstan, which makes it possible to obtain a longer exposure of the wire to cooling.
  • Such a system would be effective but the runoff and centrifugation of liquid and the humid atmosphere surrounding the machine are practically not acceptable.
  • the device according to the invention which is characterized in that it consists of a plurality of slots or grooves, formed in the external wall of the capstan and opening onto the surface of the latter, some supplied with liquid of cooling and serving to bring this liquid into contact with the wire which is wound on the capstan and whose contiguous turns form a jacket external to the capstan in which the coolant circulates and above which grooves or slots are provided which are supplied with air under pressure so as to limit the rise of the coolant on the wall of the capstan; the other grooves or slots, intended for the recovery and evacuation of the coolant, being supplied with pressurized air so as to facilitate the evacuation towards the inside of the capstan of the coolant and to perfect the drying of the wire .
  • the wire drawing machine comprises a wire drawing capstan 1 which is presented as a cylindrical body driven in rotation by a motor 2 and a transmission 3.
  • the lower part of the capstan 4 draws the wire 4a through the die 5 placed upstream.
  • Several turns are formed on the capstan by the operator when threading the machine in order to obtain the capstan effect necessary for drawing and in order to cover the cooling area on the capstan.
  • the turns of wire go up along the capstan before going to the downstream drawing block in the case of multiple drawing machines or to the wire receiving devices in the case of the last block of multiple machines. or in the case of monoblock drawing machines.
  • grooves 6 are formed slots 14 supplied with air under pressure in a manner similar to that of the orifices 10 of the grooves 9, by pipes 11a coupled to the rotary joint 12.
  • the rotary joints 8 and 12 can moreover be combined in a single double liquid-air joint.
  • the turns of wire 4a in intimate contact with each other and with the capstan, by the very fact of the drawing effort, constitute a jacket and the liquid provided by the grooves 6 creeps into the curvilinear triangular spaces 15 formed between the periphery capstan and wire turns.
  • This continuous space constitutes an Archimedes screw and the liquid is thus animated by an upward and rotary movement in the direction of the upper layers of wire. This ascent is limited by the back pressure of the air coming from the slots 14.
  • the liquid is thus forced to travel along planes substantially perpendicular to the axis of the capstan until it is collected by the slots or grooves. 9 under the action of gravity and the air injected through the orifices 10 and evacuated through the orifices 13.
  • the orifices 10, 13 and 14 are connected by means of the pipes 11, 11a and the rotary joint 12 to a suction system (not shown).
  • the device described is a mixed cooling device: direct and indirect wire, in the sense that the wire is subjected to the direct action of the coolant, on the one hand, and that the capstan is also internally cooled by the same liquid, thus participating in the cooling of the wire.
  • the efficiency of the device is further enhanced by the action of compressed air which not only dries the wire, but also helps the propagation of the coolant along the turns and facilitates its evacuation.
  • the device is completed by a chamber in which air circulates and traversed by the wire before its introduction into the soap maker and the die of the downstream drawing block.
  • the device described is, ultimately, more effective than known cooling devices which it completely overcomes all the disadvantages. It can be used alone or in conjunction with the die cooling system which, in any case, is necessary for protecting the industry itself.
  • the device is adaptable to any drawing machine of any design, single or multi-pass.
