Definitions

  • the invention relates to a for gradual bending of sheet metal or Sheet metal existing tapes in trapezoidal shape or in another for industrial Usable form suitable device, which the characteristics of the The preamble of claim 1 has.
  • a device of this type is known (DE 198 02 589 A1 and WO 99/37471).
  • the before and after that for carrying out the Bending process provided lower pressure cylinder and the associated Press rams arranged anvils and the associated upper pressure cylinders mounted in the machine in a horizontal direction so that it can move through the Follow the bending process to shorten the length of the metal sheet without tension to be able to.
  • the anvils can be moved horizontally and associated pressure cylinder structurally very complex and therefore unnecessarily expensive is.
  • Another problem is that the prior art works gradually device is relatively slow.
  • the invention has for its object a bending device of the aforementioned To train the genus in a simpler and therefore more economical and economical manner, which also allows a higher working speed.
  • This design also means that the lead and throughput speed of the strip material that is gradually advanced and bent between each preliminary step can be increased, for example by a power of ten, i. H. about ten times.
  • the actuating cylinders provided according to the invention primarily serve the clamping jaws return to their horizontal starting position after each clamping step. If the actuating cylinders are double-acting, but they can also be used at least the horizontal movements caused by the bending process to support.
  • the anvils of the bending device are individually vertically adjustable, lets the device can be used in a variety of ways because of different shapes such as trapezoidal shapes can be bent and the respective curved trapezoidal section easier from the Device can be removed even if its shape is asymmetrical.
  • anvils 2 and 3 On a bed 1 forming a foundation of the device are at a fixed distance two anvils 2 and 3 attached to each side. These anvils 2 and 3 are individual controlled, height-adjustable, as indicated by vertical double arrows 6 and 7 is.
  • the vertical adjustment of the anvils 2 and 3 takes place, for example, by means of no closer Hydraulic cylinder shown, in particular double-acting cylinder.
  • This pressure cylinder 8 contains an individually controlled axially or vertically movable piston 9, the vertical movement by a double arrow 10th is indicated.
  • the pressure cylinder 8 has a cylinder housing 11 from which the piston rod 12 of the Piston 9 protrudes. At the outer end of the piston rod 12 is a support serving pressure plate 13 attached.
  • Both the anvils 2 and 3 and the pressure cylinder 8 can be independent from each other and thus individually operated or adjusted vertically.
  • a press cylinder 14 is arranged, which one Press ram 15, which is also individually controlled vertically and coaxially to Printing cylinder 8 is adjustable, as indicated by a double arrow 16.
  • a pressure cylinder 18 or 19 is arranged above each anvil 2 or 3.
  • Each pressure cylinder 18 or 19 has a cylinder housing 20, in which axially a piston 21 is slidably arranged, the cylinder housing 20 of which extendable piston rod 22 has at its outer end a pressure plate 23 which one of the anvils 2 and 3 is opposite.
  • the pistons 21 of the pressure cylinders 18 and 19 are in the direction of the longitudinal axis of the the respective pressure cylinder can be extended and retracted, as by a vertical double arrow 25 indicated.
  • each anvil 2 and 3 there is a jaw 24 in the horizontal direction slidably mounted, as indicated by double arrows 4 and 5.
  • the anvils 2 and 3 are opposite each other on the underside of the pressure plate 23 of the relevant pressure cylinder 18 or 19 a further jaw 30 in a horizontal Directionally mounted, as indicated by double arrows 26.
  • the jaws 24 and 30 are on the anvils 2 and 3 and on the pressure plates 23 of the pressure cylinders 18 and 19 horizontally displaceable in any manner stored.
  • a sliding bearing is preferably provided in order for the desired clamping effect required surface pressure between each other keep moving parts as low as possible.
  • each Clamping jaws 24 and 30 each have their own actuating device, preferably with a double-acting hydraulic actuating cylinder 31.
  • Each actuating cylinder 31 is not with the respective jaw 24 or 30 to which it is assigned Connection 32 shown in detail - preferably mechanically - connected.
  • the bending device shown schematically in FIGS. 1 to 3 have the pressure plate 17 and the jaws 24 after a bending radius for in Trapezoidal sheets to be bent 27 rounded edges 28.
  • the each opposing pressure plate 13 or jaws 23 do not need such Bending edges to be provided, because no bending of the to be deformed around their edges Strip material or sheet 27 takes place.
  • the pressure plate 17 and the jaws 24 can arbitrarily depending on the required bending radius or profile size of the Strip material or sheet 27 are replaced.
  • the sheet 27 Since the sheet 27 is exposed between the individual jaws, it keeps its here original shape and can therefore be straight flanks of a trapezoidal profile form.
  • the movement of the jaws 24 and 30 can also be without drive, it is prefer these movements by means of the actuating cylinder 31 sensitively and individually control, or at least support.
  • both the anvils 2 and 3 and with this cooperating pressure cylinder 18 and 19 and the pressure cylinder 8 and the interacting with this press cylinder 14 individually and individually adjustable and are adjustable, can be of different depths and also asymmetrical trapezoidal shapes bend, as shown in Figures 4 to 6.
  • trapezoidal cross-sections, the like at the outer end of a curved strip material or sheet only half the height have in the middle or other area, produce, d. H.
  • Such cross sections or shapes are for the Crossbars of profile bars or profile beams, which have a trapezoidal central crossbar exhibit of interest.
  • Such profile bars or beams preferably have one welded construction on, d. H. such carriers have trapezoidal curved webs made of band material, which consists of belts consisting of undeformed band material are welded in.
