Definitions

  • the present invention relates to a method for seaming T profiles, an apparatus for implementing the method, and a profile obtained by the method.
  • T profiles obtained by profiling a sheet metal strip are known for forming support frames for false ceilings.
  • this is provided with a plurality of longitudinal seams obtained by a process comprising a first step in which a plurality of parallel slits of length L are formed in said web spaced apart by a width H, after which a transverse punching operation is effected with a punch having the same length L and width H against a die provided in a wheel facing the punching wheel.
  • Figure 1 is a plan view of the punching machine for effecting the seaming
  • Figure 2 is a side view thereof
  • Figure 3 is a section through the first punching wheel during the punching of the sheet metal strip
  • Figure 4 is a section through the second punching wheel during punching
  • Figure 5 is a side view of a T profile comprising a plurality of seams
  • Figure 6 is a cross-section therethrough on the line Vl-Vl of Figure 5
  • Figure 7 is a longitudinal section therethrough on the line VII-VII of Figure 5.
  • the method of the invention uses two pairs of punching wheels 2, 2', 4, 4' of vertical axis, the wheels 2, 4 being provided on their lateral surface with two rows of first punches 6 and second punches 8 which are faced on the wheels 2', 4' by two annular grooves 10, 12.
  • the annular groove 10 is a through groove whereas the groove 12 has a width slightly greater than the first groove and a depth such as to form a die for the second punches 8 of the wheel 4.
  • the first punches 6 have a substantially trapezoidal longitudinal section whereas the second punches 8 have a substantially rectangular section with the major side L' having a dimension greater than that of the first punches 6 and comprising a semicircular seat 14.
  • the web 16 of this is made to pass through the pairs of punching wheels 2, 2' and 4. 4'.
  • the first punches 6 form on the web of the strip a plurality of pairs of parallel incisions having a length corresponding to the length of the first punches 6 and spaced apart by a distance corresponding to the thickness of the first punches.
  • the web 16 is then subjected to the action of the second punches 8 which effect a further punching in correspondence with the first punching.
  • the sheet metal cannot further translate because of the presence of the die formed by the groove 12, but instead the most outer portion forms a kind of collar 20 which embraces the inner portion to hence prevent longitudinal slippage of the two parallel parts facing the webs and thus provide greater flexural rigidity.
