Definitions

  • This invention relates to a method of effecting the bending of a preferably hot rolled strip.
  • the present invention has the object to propose a method of the aforesaid kind, at which the described disadvantages have been eliminated. This is achieved by a method which has been given the characterizing features defined in the attached claims.
  • Fig. 1 shows a preferably hot rolled strip provided with a longitudinal groove
  • Fig. 2 shows the corner portion of an agular iron, which has been brought about by bending the strip according to Fig. 1 inward to the groove
  • Fig. 3 shows the corner portion of an angular iron,which has been brought about by bending the strip according to Fig. 1 away from the groove
  • Fig. 4 shows a preferably hot rolled strip provided with two longitudinal grooves and having sections with different material thickness
  • Figs. 5a-5j shows different types of sections, which have been manufactured by the method according to the invention
  • Fig. 6 shows a preferably hot rolled strip, which is provided with grooves located directly in front of each other on both sides of the strip.
  • the section of a preferably hot rolled strip shown in Fig. 1 is provided on one side with a groove 2, which extends along the entire length of the strip 1.
  • the depth of the groove 2 in relation to the thickness of the strip 1, of course, can be varied, but a depth of the groove 2 being about Ho % of the thickness of the strip
  • the groove 2 has a width which preferably is of the magnitude three times the strip thickness in the groove. These dimensional relations, of course, can as well be varied without thereby leaving the idea of the invention.
  • the groove 2 formed in the strip 1, of course, can be brought about in different ways. It seems suitable, however, that the strip 1 is provided with one or more grooves
  • An advantageous method of bringing about the groove 2 is to thread rings with suitably formed sections on the rolls shaping the strip 1.
  • the rings are thereafter fixed in a suitable way in desired position on the rolls. This can be carried out, for example, by means of rings filling out the intermediate spaces between the profiled rings, or in some other way .
  • these grooves act as bending notches, when the portions of the strip 1 which are located on both sides of a groove 2 are to be caused to form an angle with each other which is smaller than 180 .
  • Fig. 2 the corner of an angular iron 3 is shown, at which the flanges form an angle of 90 with each other. As appears from Fig. 2, the bending of the flanges has been carried out to the groove 2, which in Fig. 2 remains as an internal recess 2 in the corner of the angular iron
  • the angular iron 5 shown in Fig. 3 has been formed in that the flanges 6 have been bent away from the groove 2, which in Fig. 3 remains as some kind of external bevel 2" in the corner of the angular iron 5 .
  • the bending proper of the portions on both sides of a groove can be carried out by an edging press or by means of rolls.
  • a preferably hot rolled strip 7 is shown, which is provided with two grooves 8.
  • the thickness of the strip 7 between the grooves 8 is smaller than outside the grooves 8.
  • This variation in thickness of the strip 7 can be obtained in a relatively simple way, especially at hot rolling. It is thereby possible to obtain, for example, a U-section having different material thickness in the bottom and flanges. See below.
  • FIGs. 5a-5i different types of sections are shown which are manufactured of grooved, preferably hot rolled strips.
  • an angular iron is shown with legs of equal length which form a right angle with each other.
  • Fig. 5b an angular iron is shown, the legs of which form an angle of about 60° with each other. Due to the fact that relatively small edging presses can be used for forming the sections, the angle between the legs of the section can be varied in a simple manner.
  • Fig. 5c an angular iron is shown where the legs are not equally long and where the bending has been made inward to the groove. This variant is especially advantageous when it is desired to attach web reinforcing sheets. These sheets then need not be beveled at the corners, because a right-angled sheet corner can be received by the section according to Fig. 5c.
  • Pigs. 5d and 5e show Z-sections where the bending has been carted out to and, respectively, from the grooves, and where the grooves have been arranged on opposed sides of the strip.
  • Fig. 5f shows a C-section, which as well can be provided with reinforcing sheets having right-angle corners.
  • Fig. 5g a U-section is shown which has different material thickness in the bottom and legs.
  • Fig. 5h some kind of box section is shown where the portions form an angle with each other which is smaller than 90°.
  • the free ends of the strip are joined, for example by welding.
  • Fig. 5 shows a box beam with rectangular cross-section, where one corner was formed, for example, by welding together the free ends of the strip.
  • This box beam has different material thickness in walls adjacent to each other.
  • Fig. 5j a special section is shown, which is intended to illustrate that it is possible by applying the principle of the present invention to manufacture sections having different length of the flanges, walls or the like. Besides, the angle between these portions can be varied simply when using edging presses for the bending operation.
  • Fig. 6 is shown that it is, of course, also possible to imagines within the scope of the invention to provide a strip 9 with grooves 10a,10b located directly in front of each other on both sides of the strip 9.
  • the lateral edges of the grooves have a certain inclination. This inclination, of course, can be varied, but the grooves must have a somewhat distinct definition in lateral direction.
  • a further advantage with the method according to the present invention is that the holes and passages, with which the sections are to be provided, and the cross-cutting to desired lengths are carried out in flat state before the bending, which simplifies in a high degree the equipment necessary therefor.
