Definitions

  • the present invention relates to a method and device for producing helically seamed tube from a strip-shaped profiled blank.
  • the objects of the present invention include elimination of these drawbacks and achievement of such a method and device that one and the same machine can be used without exchangeable tools, merely by performing certain adjustments, to manufacture tubes of even considerably different diameters and even to manufacture conical tube sections by means of which tubes of different diameters may be connected to each other.
  • One of the present inventions most essential advantages is the simplicity of the devices required in it, and the fact that one is enabled to change the production of the seaming machine very rapidly from one type of tube to another, all of which results in considerable reduction of the production costs.
  • FIG. I shows a device for use according to the invention, seen from one side.
  • FIG. 2 shows the same device, seen from above.
  • FIG. 3 shows, in the form of profile diagrams, the different phases of forming the helical seam.
  • FIG. 4 shows some other profile shapes of the helical seam which can be produced by means of the invention.
  • FIG. 5 is an enlarged presentation of part of FIG. 1.
  • FIG. 6 shows, from the side as in FIG. 1, another embodiment of the device used according to the invention.
  • the metal strip 1 enters the machine, drawn by the rolls 3. At the same time the rolls 3 shape the strip blank 1 to have the desired profile so that a profiled strip 2 is produced, which is fed onwards in the device.
  • the strip 2 then passes through an arc of 360, forming a length of the tube corresponding to one lead of the helical or screw line formed by the helical seam, and arrives at the rolling device 4, which initiates the finishing of the helical seam. On the length of the next lead of the screw line, starting at the rolling device 4, two further rolling devices 5 and 6 have been placed, which finish the helical seam.
  • the rolling devices 5 and 6 are displaced in their guides 8.
  • oblong openings in the end plate 7 act as guides
  • the rolling devices 5 and 6 have been mounted on slides 10, both slides moving along two guide bars, and by turning the spindle 12, which acts on screw spindles 11 interacting with the slides 10, the slides 10 and the rolling devices 5 and 6 along with them may be positioned as desired.
  • the spindle 12 (FIG. 6) may also be arranged, e.g.
  • FIG. 3 the three different phases a, b and c occurring in the manufacturing of one type of helical seam are shown. These profile shapes of the seam are produced in the device at the pints indicated by the same reference symbols in FIG. 3.
  • FIG. 4 some other such helical seam profiles are presented which can be produced with a device and method according to the'invention.
  • a device according to the invention can naturally be provided with more than three rolling devices, but there is no reason for this as a rule.
  • the device would merely become unnecessarily complicated, and achievement of certain adjustments would be rendered more difficult.
  • various supporting and bracing elements such as rolls, especially when manufacturing of large-diameter tubes is concerned, but such rolls are obviously in no wise connected with the producing of the helical seam itself, that is, they do not actually fall within the sphere of the invention.
  • a device devoid of mandrel for making rigid helically seamed tubing comprising a device for profiling and feeding a metal strip, at least three rolling devices, means rotating one of said rolling devices in synchronism with the speed of said feeding device, said one rolling device engaging and turning the metal strip to the extent of 360 and bringing its edges into seaming contact with each other, the other two rolling devices being spaced from the first-mentioned rolling device to the extent of a pitch of the helical seam and engaging the rolled strip to join its helically extending seams, two guides extending at an acute angle to each other and carrying said two other rolling devices which are movable upon said guides and screw spindles carried by said guides and engaging said two other rolling devices and geared to a common shaft for simultaneously varying their distances from the first-mentioned rolling device while the device is in operation.
