Definitions

  • the invention relates to a connection according to claim 1 and a device according to claim 19.
  • metal sheets with each other connect, be it to make smaller metal sheets bigger overall, be it to manufacture tubular structures or be it individually manufactured beforehand To connect sheet metal parts to each other.
  • the object of the invention is a connection of sheet metal edges and a device to establish the connection to a closed tubular profile, with which you can be very flexible, fast, at low cost, without large equipment Effort to connect quietly and with little loss which are still dynamic and / or statically excellent values in terms of Area, the section modulus, the moment of inertia, etc. for which various sheet thicknesses, e.g. already in the experiment from 0.5 mm to 2 mm steel sheet delivers good results for a wide variety of materials is usable, the connection of at least two sheet metal layers allowed, aesthetically is flawless, is environmentally friendly and is able to use the technology of To jump ahead of connections of this kind.
  • this object is at least partially characterized by the features of relevant claims resolved.
  • the 5 has an endless profile 11 made of galvanized sheet steel. It has about Rectangular cross section with a bottom wall 12, two side walls 13, 14 and one Top wall 16.
  • the steel sheet has a thickness of 0.88 mm, is galvanized and comes from a coil.
  • the corners 17, 18, the knees 19 and the corners 21, 22 bent.
  • there is already one S-shaped offset 23 is provided so that the top 24 of a first sheet layer 26 aligned with the top 27 of the second sheet metal layer 28 and in this respect one to the outside consistently flat surface.
  • the right edge 29 of the first sheet layer 26 lies in the osculation of the offset 23.
  • the left edge 31 lies in the exemplary embodiment 5 about 10 mm further to the left, so that the additional coil width effort is only 10 mm with a profile of about 37 x 47 mm.
  • the profile 11 does not yet have the figure shown in FIG. 5.
  • an arm 32 which at its lower end into a horizontal rod 33, which can be loaded on a train directed to the right is.
  • the horizontal rod 33 is stationary, while the profile 11 is in the direction of arrow 34 moves.
  • the rod 33 has an external thread 36 on one Adjusting nut 37 is screwed. Preventing a washer prevents Adjusting nut 37 a shaped part 38 to move further than drawn to the right, which is crossed by the rod 33.
  • the rod crosses to the left of fitting 38 33 a coaxial pressure pipe 39 which is located on the fitting 38 with its right edge and is supported with its left edge on the molding 41, which is also from the Rod 33 is crossed.
  • the fitting 41 belongs to a piercing cutting station 42 and the fitting 38 belongs to a joining station 43. Both stations are spatial here clearly separated from each other. However, they could also be combined and likewise be well divided into several stations. E.g. the plunge cutting station 42 in be divided into two different stations, one of which only cuts and just bends the other one up.
  • the profile 11 comes from the left in the drawn in Fig. 5 Shape, but still without the holes 44, 46, 47 arranged in sequence, 48, which form a linear array of holes. All holes have the same Shape. Analogous to the sewing machine principle, the holes could also be on one single or double curved curve and / or - depending on the purpose - have different shapes.
  • the fitting 41 is supported and can therefore, because it lies indirectly on the counter surface 49, do not be pressed down.
  • the fitting 41 has an upper side 51 on which the underside of the top wall 16 can support. A pressure exerted on the top wall 16 from above is therefore in the counter surface 49 initiated.
  • a longitudinal groove 53 is machined into the top 51 which is several times as deep as the sheet layers 26, 28 are thick.
  • a circular disk 54 is above the counter surface 49 and above the longitudinal groove 53 arranged, which is rotatable about a geometric center axis 62. It has a circular shape Circumference 63. The distance between center axis 62 and top side 24 is chosen so that the circumference 63 rests on it and thus the first sheet layer 26 also low holds. Piercing incisors 64, 66 protrude beyond the circumference 63, in pairs opposite and angularly offset by 60 degrees. In effect is their circumferential distance such that with a regular spacing of the holes 44, 46, 47, 48 the hole 46 has just been cut from the incisor tooth 66 Hole 44 is currently cut from the incisor tooth 64 and soon the Cutting incisor 67 begins its work.
  • the shape of the incisor tooth 64 effects the specific one Configuration of the metal tabs to be discussed.
  • the top 69 started in plunge 73, and the incisor 67 later then stab in area 74. This was done in the left area on the inlet side the longitudinal groove 53.
  • the circular disc 54 rotated in the direction of arrow 76 has and the profile 11 was moved to the right according to the arrow 34 was off the first sheet layer 26 a first sheet tab 76 and below a second sheet tab 77 peeled out.
  • the side edges 78, 79 these were the sharp ones Cutting 81, 82 of the front flank 68 is decisive.
  • the interface 83 between the longer 69 has a longer sheet metal tab 76 and a third sheet metal tab 84, that has cut It also has the interface 86 between the second Sheet metal tab 77 and a fourth sheet tab 87 concerned.
  • the much shorter sheet metal tabs 84, 87 are bent downward by approximately 45 degrees.
  • the area 88 was cut completely and the Sheet metal tabs 76, 77 also inward at approximately half a right angle pressed down. At the end there is a small, crescent-shaped dent 89 down. Since the knee 91 for the first sheet metal tab 76 is higher than the corresponding one The knee for the second sheet cloth 77 arises from Fig.
  • the shaped piece 41 has a through bore which is coaxial to the geometric longitudinal axis 107 108, with which it is kept riding on the horizontal rod 33, but can not move further to the right, as the pressure pipe 39 indirectly and the Setting nut 37 dictated immediately.
  • the molding 41 is so far floating - as the way, the fitting 38 because of the same construction in so far - as it pivot about the geometric longitudinal axis 107 and so bumps and can adapt to other non-ideal working conditions.
  • the fitting 41 has one plane 109 parallel to the geometrical longitudinal axis 107 corresponding to the course of the plane the bottom wall 12. If this had a different shape, the level 109 would have to be complementary.
  • top wall 118 complements the shape of the underside 52. It the top wall 118 also runs into the front wall 132 via skid radii 119, 121 and over into the rear wall 133, so that bumps here too due to the skid radii 119, 121 are run over and can even be smoothed if necessary.
  • incisor teeth abrasion and stress cause is in the top wall 118 an upwardly open-edged, rectangular receiving groove 122 incorporated, in which a cutting insert 123 according to FIGS. 1d to 1f is seated.
  • This is made of a special material, the material 2080, which has a long service life brings with it.
  • the cutting insert 123 sits in the receiving groove practically without play 122. It also has the skid radii 119, 121.
  • the longitudinal groove 53 is ground in it, which is open both upwards and forwards as well as backwards.
  • the Cutting insert 123 is held by two hexagon screws 124, 126, which in Blind hole threaded holes 127, 128 are screwed in, the latter axially parallel to the geometric longitudinal axis 107.
  • the under the respective head of the hexagon screws 124, 126 clamped washers 129, 131 are supported on the one hand from the end faces 132 and 133 and on the other hand onto the end faces aligned with them 134, 136 of the cutting insert 123, so that it is geometrically exactly in the longitudinal direction is held immovable, but slightly after loosening the screws 124, 126 can be replaced.
  • skid radii 137, 138 on the shaped piece 41, which with respect to the side walls 13, 14 of the profile 11 have the same effect as already described using other skid radii. Analogous to these skid radii also the fitting 38 skid radii.
  • profile 11 If profile 11 is now moved further to the right in the direction of arrow 34, then bump the first and second tabs of the hole 46 onto a leading edge 94 of the Fitting 38. This is also supported downwards by a counter surface 96, as previously described for the fitting 41.
  • first and second sheet metal tabs meet the leading edge 94, they become in the Turned clockwise around their respective knees and the underside of the first sheet metal tab grinds on the flat top 97 of the fitting 38.
  • the extent 99 expresses the more than in Fig. 2 to the back bent first sheet metal tab 76 around the knee 91 so that 76 and 77 as shown in Fig.
  • the third sheet metal tab 84 and the fourth sheet metal tab 87 also become lower pressed. However, since these metal tabs have their interface 86, 83 close to the beginning of the Holes 44 stick, they are short according to the drawing and can never the top 97 to reach. You may not do this either, because otherwise this part of the connection itself would open again.
  • the metal tabs 76, 77, 84, 87 are supported on the longitudinal edges 92, 93 onwards.
  • the sheet metal tabs 76, 77 mainly hold in the transverse direction, but also in Consequence also existing non-positive and positive connection the Sheet metal tabs 84 and 87.
  • FIG. 7 shows: at work cut the cutting edges 81, 82 along the longitudinal edges 92, 93 and this results in Transition from the first sheet layer 26 to the second sheet layer 28 each has a cutting burr 102, 103, which spreads out thinner downwards and also in the transverse direction 7 shows a transverse movement of the first sheet metal layer 26 relative to the second sheet metal layer 28 difficult.
  • each cutting edge 81, 82 presses the upper edge area of the hole 48 - as far as it passes through the second sheet layer 28 - in the manner of a Cut edge feeder 104, 106, as is known from normal cutting. In the area of the cut edge feeder 104, 106 is then at least in some cases also cold welding, i.e. a cohesive connection.
  • the embodiment shows the production of a closed tube.
  • the invention but also provides the connection of the edges on flat metal sheets.
  • the parts connected to one another according to the invention no longer have to or less necessarily lie in a single plane.
  • the parts can also be two-dimensional or be three-dimensionally curved.
  • the invention works much faster, quieter, with less energy, with less material, more environmentally friendly, without harmful structural changes etc., like the known techniques.
