Definitions

  • the present invention concerns a coiling device and the relative method for long metal products, ferrous or not, as obtained from drawing or rolling operations, whether done hot or cold.
  • the invention concerns the coiling of wire, bars, flat strips, rods (smooth or ribbed), or tubes, having a transverse section that is round, square, rectangular, hexagonal or otherwise, of various sizes.
  • the invention concerns the device to guide and contain the coiled product, on the winding mandrel, in order to contain it laterally and to impose on the forming coil the desired external form.
  • the winding mandrel may have a horizontal, vertical or inclined axis of rotation.
  • the invention is applied to coiling machines with cantilevered axis.
  • BACKGROUND OF THE INVENTION In the state of the art, the problems connected to coiling, on a continuously rotating mandrel, a long metal product, either rolled or drawn, traveling at high speed, to be wound in contiguous, adjacent and superimposed spirals, in a uniform manner, so as to form very compact coils, are known. It is known that the operation to form the coil, so that the spirals are compact and uniformly distributed in every layer and for the whole longitudinal extension of the coil, is very delicate. The problem of easily removing the finished coils from the mandrel is also known.
  • the European patent EP-B-1.126.934 discloses a coiling machine which comprises suitable guides, substantially semi-cylindrical in shape, otherwise known as flaps or insertion blades.
  • Said guides are able to intercept the metal product to be wound, as it arrives from the rolling mill or the drawing machine, and are able to facilitate the formation of the first spirals of the coil on the mandrel.
  • This known coiling machine which has the axis of the mandrel cantilevered, also comprises a mobile containing plate to frontally contain the coil, which plate cooperates with the terminal, cantilevered part of the mandrel, and which can be arranged in the following two limit positions: a first position for the formation of the coil, wherein the containing plate is orthogonal to the axis of the mandrel and coaxial therewith, and a second position wherein the containing plate is rotated by about 90° and arranged substantially parallel to the axis of the mandrel, in a position of non-interference with the path on which the finished coil is discharged.
  • the US Patent US-A-3,592,399 discloses an apparatus to grip and wind the leading end, or head, of a rolled product onto a mandrel, rotating around a horizontal axis, which is provided with a first containing plate to contain the coil to be formed, arranged perpendicular to the mandrel, and a second containing plate to contain the coil laterally.
  • This second plate is autonomous and movable with respect to the mandrel between an operating position, wherein it is parallel to the first plate, and an extraction position, wherein it is arranged distant from the mandrel and rotated laterally by 90° with respect thereto.
  • the second plate is mounted rotatable on a cylindrical supporting element, which in turn can rotate on a vertical support.
  • the second containing plate has an axis of rotation which does not coincide with that of the mandrel and is provided with an annular groove which has a circular surface eccentric with respect to the outer surface of the mandrel.
  • the two surfaces Due to the misalignment of the second containing plate and the mandrel, the two surfaces form a clamping channel with a variable section, into which the leading end of the rolled product to be wound enters and is locked.
  • the apparatus comprises a guide element, substantially semi-circular in shape, which in the operating position cooperates with the aforesaid clamping channel until the first spirals have been wound onto the mandrel. After some spirals have been formed, the guide element is distanced from the mandrel and raised to an inactive position. This known apparatus does not allow to obtain a clamping of the leading end which is repeatable and reliable.
  • One purpose of the present invention is to achieve a coiling device for long metal products which will guarantee a considerable rapidity in installing the mobile frontal containing means that cooperate with the end part of the mandrel. Another purpose of the invention is to guarantee the correct performance of the coiling process. Another purpose pursued by the device according to the invention is to improve the quality of the final coil in terms of winding, compactness, density and holding capacity of the spirals. A further purpose of the invention is to prevent damage and a reduced quality of the product. It is also a purpose of the invention to simplify maintenance operations on said device.
  • the purposes are achieved also by means of a coiling method for the long metal product which has the characteristics of claim 17.
  • the device and method according to the present invention are applied to machines for coiling long metal products, obtained from rolling or drawing operations, whether performed hot or cold.
  • the products can be irrespectively wire, bars, flat strips, rods (smooth or ribbed), tubes, both of ferrous material such as steels with low, medium or high carbon content, stainless steels, alloyed or other, and also non-ferrous material, such as aluminum, copper or other.
  • the invention is applied to coiling machines or reeling machines which have a mandrel with a cantilevered axis.
  • Said long metal products can have any transverse section whatsoever, that is, round, square, rectangular, hexagonal or otherwise, particularly, but not restrictively, with diameters between 8 mm and 52 mm or, in the case of bars or flat strips, with a transverse section between 60 mm 2 (for example 20 mm x 3 mm) and 1400 mm 2 (for example 70 mm x 20 mm) .
  • long metal product can be taken to mean any of the above products, and also any similar or comparable products, traveling up to more than
  • the gripping device comprises pincer-type clamping means, able to be selectively activated, which are arranged in correspondence with the outer surface of said mandrel.
  • the pincer means comprise four pincers, which rotate solidly with the mandrel, arranged at 90° one with respect to the other, and which are able to clamp the initial segment of the metal product.
  • the clamping steps are performed substantially as follows. The leading end of the metal product enters into a device to distribute the spirals from which it is introduced, tangentially with respect to the mandrel, into a guide and containing device, or flap, which guides the leading end of the product by means of a groove.
  • This initial step of the winding provides that the leading end of the product is conveyed by the flap inside a clamping zone.
  • said clamping zone comprises an annular containing channel, called rotary channel, made on a transverse plate arranged laterally to the mandrel.
  • the annular channel can have a cylindrical shape, or preferably like a truncated cone; then in a section along a plane passing through the axis of the mandrel, it has a shape respectively rectangular, square or preferably trapezoid or wedge-shaped.
  • the transverse plate can be completely external to the mandrel, or partly inside it.
  • the groove of the flap comprises a lateral wall which, at least in the flap that receives the leading end of the product, has an inclined or helical development, with an inclination sufficient to guide the leading end of the product towards the clamping zone.
  • the groove with the inclined or helical wall can be limited to the upper flap, or to the lower flap, or can comprise at least part of both. From the moment it arrives in correspondence with the clamping zone, the initial segment of the metal product cooperates with the clamping means.
  • the clamping means at least one in number, enter into action in a well-defined arc of the circumference of the mandrel, clamping the metal product onto the latter.
  • the clamping means can grip in sequence or simultaneously, in order to firmly anchor the initial part of the metal product against the clamping zone.
  • Simultaneous clamping occurs when a sufficient segment of the metal product has already wound around the clamping zone.
  • the first winding step that is, until the clamping means intervene, the high adherence of the metal product against the walls of the clamping zone is normally exploited.
  • this initial segment of the metal product has a length of between a little less than one and two spirals, according to the various factors connected to the structure of the coiling device and the material to be wound (shape, size, etc.).
