Definitions

  • the present invention refers to an apparatus for manufacturing pipes that comprises two production lines placed side-by-side.
  • production lines able to form a pipe from a roll of sheet metal strip which generally comprise at least the operating units adapted to deform, to shape and to weld the metal strip and to carry out the finishing of the welded pipe - will not be described in detail herein because they are per se known.
  • the present invention refers to an apparatus for manufacturing pipes comprising two production lines placed side-by-side, near each other; this object is achieved by means of a manufacturing apparatus having at least the characterising features illustrated in claim 1.
  • Figure 1 shows diagrammatically a front view of a pipe manufacturing apparatus realised according to the invention, denoted as a whole with the reference numeral 1, which comprises two pipe production lines (2, 3) placed side-by-side and independent of each other, offset from each other both vertically (in the embodiment described herein, the operating units of the production line 2 are placed higher than the corresponding operating units of the production line 3) and horizontally, that is (as can be seen better in the top view of Figure 2), the operating units of a production line (line 2 in the embodiment described herein) are offset with respect to the corresponding operating units of the other production line (line 3 in the embodiment described herein).
  • the reference numeral 1 which comprises two pipe production lines (2, 3) placed side-by-side and independent of each other, offset from each other both vertically (in the embodiment described herein, the operating units of the production line 2 are placed higher than the corresponding operating units of the production line 3) and horizontally, that is (as can be seen better in the top view of Figure 2), the operating units of a
  • the operating units of the production line situated higher up are offset with respect to the corresponding operating units belonging to the other production line (line 3 in the embodiment described herein).
  • the Applicant has modified the double reel 4 ( Figure 3) from which the steel strip 10 that feeds a production line (2 or 3) is unwound and the drawing off units 5 ( Figures 4 and 5) situated downstream of the shaping and welding preparation units 6 and of the calibrating unit 7; the operating units 6 and 7 and the other operating units of the production lines 2 and 3 have not been modified and will not, therefore, be described because they are per se known.
  • Figure 2 shows diagrammatically a top view of the apparatus 1 of Figure 1, from which it can be better observed that:
  • Figure 3 shows diagrammatically a side view (Figure 3a), a front view ( Figure 3b) and a top view (Figure 3c) of a pair of double reels 4, each of which feeds a production line (2, 3).
  • the double reels 4 differ from those used for the production lines of the prior art in that the frame 8 which carries the two reels that form a double reel 4 turns around a horizontal axis 9 instead of around a vertical axis, as occurs in the double reels of the
  • Figure 4 shows diagrammatically a front view ( Figure 4a) and a top view, partially in section ( Figure 4b) of one of the drawing off units 5 belonging to a production line (2, 3) and situated downstream ( Figures 1 and 2) of the shaping and welding preparation units 6 and of the calibrating unit 7.
  • a drawing off unit 5 comprises a frame 13 which carries drawing rollers 11, guide rollers 12 mounted idly on the frame 13 and motorization means (not described because they are per se known and omitted in Figures 4 and 5) able to drive the drawing rollers 11.
  • a drawing unit 5 realised according to the invention differs from the drawing units of the prior art in that the drawing rollers 11 and the guide rollers 12 are not placed on the inside of the frame 13, but they are carried cantilever by the frame 13, as can be seen better in Figure 5.
  • the drawing rollers 11 and the guide rollers 12 are therefore placed on the outside of the frame 13: this allows the operator an easy access to the rollers 11 and 12 to replace them, if and when it is necessary, without having to remove at least part of the frame 13 to access the rollers 11 and/or 12 which, in the drawing off units of the prior art, are situated inside the frame 13.
  • Figure 5 shows diagrammatically two details of the drawing off units 5 of Figure 4; in particular Figure 5a shows diagrammatically the frame 13 which carries cantilever the drawing rollers 11, Figure 5b shows diagrammatically the frame 13 which carries cantilever the guide rollers 12.
