Definitions

  • the present invention relates to a cold forming system of a profile from a strip of sheet metal.
  • the sheet metal strip first passes into cutting means thereof in the form of sections or individual plates, then these plates are introduced by feeding means into a press for example transfer type.
  • This feeding of the press in sections is then transversely relative to its longitudinal axis, then the sections pass in a succession of progressive forming stations of this section in the form of the section of desired profile, these progressive forming stations having a determined step by the length of each profile section.
  • the object of the invention is therefore to solve these problems.
  • the subject of the invention is a cold forming system of a profile from a sheet metal strip, characterized in that it comprises a press comprising a succession of progressive forming stations of the band under the shape of the profile, having a determined pitch, between a feed inlet of the band associated with feeding means of this band in steps and a output of the profile, in that the output of the press is associated with means of complementary treatment of the profile obtained, in that the profile is presented in the form of a tube, and in that the additional processing means of the profile include means for welding the edges opposite the profile.
  • FIG. 1 shows a cold forming system. of a profile from a strip of sheet metal.
  • Such a system comprises a press for example transfer type designated by general reference 3 comprising a succession of progressive forming of the strip in the form of the profile and having a determined pitch, between a supply input of the band designated by the reference 4 in this figure, associated with feeding means of this band per step for example corresponding to the pitch of the forming stations of the press, these feeding means being designated by the general reference 5 on this figure and an output of the section 2, designated by the general reference 6.
  • a press for example transfer type designated by general reference 3 comprising a succession of progressive forming of the strip in the form of the profile and having a determined pitch, between a supply input of the band designated by the reference 4 in this figure, associated with feeding means of this band per step for example corresponding to the pitch of the forming stations of the press, these feeding means being designated by the general reference 5 on this figure and an output of the section 2, designated by the general reference 6.
  • the feeding step of the band may for example be different from the pitch of the forming stations of the hurry.
  • these feed means comprise by example of the rollers or motorized pressure rollers designated by the references 7 and 8 in this figure, whose rotation is controlled to drive a advance by step of the sheet metal band in the press, the step advance of the band corresponding for example to the step of the successive posts of the press.
  • the press has a succession of progressive forming stations of the band in the form of a profile.
  • This press has any appropriate structure known and having a movable part or punch and a fixed part or matrix designated by general references 9 and 10 in FIGS. 2 to 13, making it possible to form the strip in the form of a profile, this strip or profile being designated by the references 1 and 2 in these figures.
  • these additional processing means of the profile may include means for welding the edges opposite it, these means being designated by the general reference 11 in Figure 1.
  • the complementary processing means can also include means for cutting the profile into designated sections of section by the general reference 12 in this figure.
  • any profile section length can be considered without changing the rest of the system.
  • the system according to the invention makes it possible to obtain profiles of any length and these can be used in applications that could not be considered in the state of the art, for example, helical springs, tubes, etc ...
