Definitions

  • the invention relates to a device for the gradual bending of strips made of sheet metal in a trapezoidal shape.
  • the device can be used not only for the bending of trapezoidal shapes, but also for the bending of metal sheets in wave form and in rectangular shapes.
  • the sheets to be bent are not only suitable for t and T beams, but also for other industrial uses.
  • the invention has for its object to be able to economically bend strips made of sheet metal in a Wei.se in a form that with short processing times in the area of the bending points no inadmissible changes in the material thickness and the material structure occurred.
  • FIG. 2 shows a view of the device as in FIG. 1, but with a band consisting of sheet metal being inserted or run in laterally and the interacting parts of the bending device being in their starting position before the bending process is started,
  • Fig. 3 is a view as in Figs. 1 and 2, wherein the device is in a position at the end of a bending process
  • Fig. 4 is a view of the device as in Fig. 1 to 3, after the one
  • Section of the same is bent trapezoidal.
  • two anvils 2 and 3 are arranged at a lateral distance from one another and are mounted so as to be movable relative to one another and away from one another.
  • a pressure cylinder 4 is immovably arranged between the anvils 2 and 3, which contains an axially movable piston 5, the piston rod 6 of which can be extended and retracted from the cylinder housing 7 in the direction of the longitudinal axis 8 of the pressure cylinder 4.
  • a counter-pressure plate 9 serving as a support is attached.
  • a press 10 which has a press ram 11 which is moved by the press 10 in the direction of the longitudinal axis 8 of the
  • Printing cylinder 4 can extend and retract, as indicated by a double arrow 12 shown in FIG. 3.
  • the press ram 11 has at its free or lower end a pressure plate 13 which corresponds in its base area to the size of the counter-pressure plate 9 of the pressure cylinder 4.
  • a further pressure cylinder 14 or 15 is arranged on a frame or frame of the device, not shown, which contains an axially displaceable piston 17 in a cylinder housing 16, the piston rod 18 of which can be extended from the cylinder housing 16 at its outer end has a pressure plate 19, which is opposite each other at the upper end of the anvil 2 or 3 corresponding counter-pressure plate 20.
  • the pistons 17 of the pressure cylinders 15 and 16 can be moved in the direction of the longitudinal axis 21 of the respective pressure cylinder 14 or 15, as indicated by a vertical double arrow 22 in FIG. 3.

  • Double arrows 23 can be moved, as shown in FIG. 3.
  • the pressure plate 13 and the counter-pressure plates 20 have rounded edges 25 (FIG. 4) according to a bending radius for sheets 24 to be bent in a trapezoidal shape.
  • the opposing counter-pressure plate 9 and the opposing pressure plates 19 need not be provided with such bending edges, because no bending of the sheet 24 to be deformed takes place around these plates.
  • the pressure plate 13 and the counter pressure plate 20 can be replaced as desired, depending on the desired bending radius or profile size.
  • a flat sheet 24 is first inserted into the device opened according to FIG. 1 and stopped in the desired bending position. Then the press ram 11 of the press 10 and the pistons 17 of the pressure cylinders 14 and 15 are extended in order to place the sheet, which is still flat or the section thereof intended for bending, on the counter-pressure plates 20 of the anvils 2 and
  • the ram 11 is extended further and at the same time the piston 5 of the pressure cylinder 4 is retracted, so that the part of the sheet 24 located between the anvils 2 and 3 is deformed, as shown in FIG. 3.
