Definitions

  • the present invention relates to a static device for mechanical cleaning of the wire rod in the steel wire drawing lines, according to the preamble of claim 1 (see for example US-A-3,081,524).
  • the wire rod being a semi-finished product obtained hot
  • the wire rod is covered with layers of oxide, hydroxide, scale, etc., which are formed during the manufacturing and / or storage process, these layers must be removed before drawing, since their presence mainly involves the production of low quality yarns, rapid wear of the dies and a sharp reduction in the drawing speed.
  • the wire rod In the first zone, also called mechanical flaking, the wire rod is forced to follow a tortuous path through a series of rollers arranged in succession and extending in different planes, so as to undergo alternating flexions determining the separation coating layers, harder and less deformable than non-oxidized steel.
  • the oxide layers, of smaller dimensions, which are embedded in the microcavities of the surface of the wire rod, which are typically contracted "in orange peel", are eliminated.
  • the preparation is completed by means of compressed air jets which strike the wire rod and remove the residual oxide powders still adhering thereto.
  • the devices which currently equip the second zone all act by rotary brush systems located around the wire rod and capable of interacting tangentially with the latter as it advances along the preparation zone.
  • some devices provide planetary brush systems rotating around the wire rod, so as to print on its surface artificial grooves which are capable of to retain the powdered lubricant.
  • the object of the invention is to eliminate the drawbacks which have just been described.
  • the fundamental advantage of the invention lies in the great simplicity of construction which results in a fairly low cost.
  • the invention which is further characterized by the absence of mobile elements for transmitting movement, has a very high reliability, despite the hostility of the environment in which it operates.
  • Another advantage is represented by the fact that the backlash resulting from the wear of the steel wool layer is carried out in a very simple manner.
  • the device is further characterized by an efficient and selective removal of the oxide particles which results in better quality of the wire and much less wear on the dies.
  • the invention relates to a static device 1 for mechanical cleaning of the wire rod 2, in the lines 3 for drawing steel wires.
  • the device 1 is placed in correspondence with a zone 4 for the mechanical preparation of the wire rod 2, arranged upstream from the true drawing line 3.
  • This preparation zone 4 is in turn divided into three stations 5, 7, 8, respectively mechanical flaking, intermediate preparation, final blowing of the wire rod 2.
  • the device 1 described is located at the intermediate station 7 of the preparation zone 4 and essentially provides a press 9 supported by two horizontal axes 10, having a plurality of opposite working elements 11, arranged bilaterally with respect to the wire rod 2 and vice versa mobile, towards each other, transversely to the direction of stretching along horizontal guides 12, by activation of respective drive means 13.
  • the working elements 11 are supported by a support frame bearing on the horizontal axes 10 and preferably comprise flat steel plates having working surfaces 15 in the shape of a "V" arranged in a package, separated by spacers 21 and made monolithic to each other by long steel bolts 14 so that they are nested one inside the other when the press 9 is actuated and therefore compress and retain on the wire machine 2 advancing along the drawing direction, a layer 16 of steel wool interposed in the working elements 11.
  • the spacers 21 are arranged in correspondence with a single series of working elements 11, that is to say those which are solid of the frame 22; the remaining working elements 11, which on the contrary are movable relative to the frame 22, are devoid of the spacers 21 and are capable of floating freely between the working elements 11 fixed.
  • the means 13 for driving the press 9 preferably comprise a linear pneumatic actuator 17 which constantly presses the working elements 11 and consequently the layer 16 of steel wool against the wire rod 2 by applying a force of constant intensity .
  • the press 9 thus actuated is able to automatically make up for the play resulting from the wear of the layer 16 of steel wool and, taking into account the compressibility of the air, is also in a state of adapt elastically to any irregularities in the size of the wire rod 2, in any case avoiding using and smoothing the characteristic surface of this wire rod which remains naturally provided with small craters.
  • said embodiment comprising alternating plates in a package also promotes the evacuation of the heat of friction which develops during the cleaning operation, this evacuation being also aided by the addition of a series of holes 19 provided on work items 11.
  • the press 9 is supported by the pins 10 by means of interleaved supports 50, which oscillate so as to allow said press to be automatically centered on the wire rod 2.
  • drive means 13 can be designed as an alternative to that described, providing for the replacement of the pneumatic actuator by a mechanical actuator acting against the action of springs or other equivalent means.
