Definitions

  • the invention relates to a device for Sliding drawing bending of strips, especially for the Manufacture of lightweight profiles, such as pipes, with one Forming tool composed of several parts a profile that starts from a slot in the Entry area progressively into the pulling direction Final shape of the formed band passes.
  • Sliding drawing bending or sliding drawing profiling is a special bending forming with straight relative Movement between tool and workpiece (German standards DIN 8586, April 1971, page 3, picture 9; Technology for Manufacture of lightweight profiles, VEB German publisher for Basic industry, p.40). It will be especially for the Manufacture of lightweight profiles applied.
  • the forming tool can consist of individual plate-shaped matrices consist of each are composed of several parts. In any case it is necessary to put the band outside the forming tool preform or sharpen it into the forming tool to be able to introduce. It is understood that such Work is quite expensive. It also falls because of the preparatory work to be done by hand Initial section, which is usually for a Further processing is not to be used.
  • a known device for slide drawing bending of strips for the manufacture of pipes consists of two in Pull direction of the tape arranged one behind the other Share (DE-OS 14 52 397).
  • the ribbon is given an arcuate profile, while in the second part is formed into a full pipe.
  • the first part shows how to give an arcuate profile the device a variety of vertical and arranged side by side, in the direction of pull extending slats.
  • the slats form one Profile that in the entrance area as a flat slot is trained and progressing in the direction of pull in passes an arcuate slot.
  • the first one Second formed part of the device Formed part also has lamellae in this Case but are arranged horizontally one above the other and only form an outer shell by one semicircular shell progressing in the direction of drawing change into a closed round profile.
  • the known device are not special precautions for commissioning, that is, the introduction of the Band hit in the given profile.
  • the invention has for its object a To provide a device for slide drawing bending of strips, which is easy to put into operation and at their Use practically no unusable tape start section arises.
  • the forming tool can be made solid.
  • the forming tool is preferably a multi-stage tool Formed die, the individual steps from in Direction of drawing arranged one behind the other, divided Plates exist.
  • the band to be reshaped is after another Design provided that the forming tool has such a profile that it is on every section of the Forming section same forming work in slide drawing bending accomplishes.
  • the individual levels of the matrices can be individual procedure, but it is easy for one reason designed device better if the stages of Matrices on one side and those on the other side each as a sentence on a cassette Sledge or trolley using an actuator can be moved apart and moved together. Then that is combined with the effect that a targeted gradual deformation of the tape in the direction of pull when Moving together takes place.
  • the device shown in Figure 1 Slidebending from strips to tubes encased in cassettes 1a, 1b as a forming tool, several die stages 2a, 2b, 3a, 3b, 4a, 4b, only three of which have reference numerals are provided.
  • the cassettes 1a, 1b are on slides 5a, 5b by means of an adjusting device 6 Screw spindle 7 on a machine frame 8 movable.
  • Each Matrix level 2a, 2b, 3a, 3b, 4a, 4b consists of two in Direction of the arrows P of Figure 2 open and close Halves 2a, 2b, 3a, 3b, 4a, 4b.
  • the individual matrix levels 2a, 2b, 3a, 3b, 4a, 4b have a different profile, such as it for example in Figure 2 for the one after the other arranged stages is shown.
  • the profile 9 as Slit be formed so that this slot 9 still level band B to be formed gives a guide.
  • This slot 9 can be made in the first die stage 2a, 2b overall straight or slightly curved.
  • the slot 9 should be on Edges are already curved, as is shown in FIG. 2 even for the first die level 2a, 2b.
  • volume B becomes increasingly wider deformed, preferably slightly in the middle is bulged, as for the die level 3a, 3b is shown.
  • the Matrix level 4a, 4b is shown. It goes without saying that there is at least one behind the matrix level 4 must connect another die level if as Lightweight profile a tube is to be created.
  • the operation of the forming tool of the device for slide drawing bending is the following:
  • the band to be formed B is opened in the positioned necessary height to it with its Edges in the individual die halves To be able to introduce 2a, 2b, 3a, 3b, 4a, 4b.
  • the tape B is found of itself in the slot 9 or profile of the individual Matrix levels under gradually increasing Forming a so that it, as shown in Figure 2, the in the individual die levels 2a, 2b, 3a, 3b, 4a, 4b positions shown.
  • the tape B at Band standstill in this form introduced into the matrix then it can be from not shown Traction means of the device for slide drawing bending through the Forming tool are pulled, then it is continuously formed.
  • the place of individual die levels 2a, 2b, 3a, 3b, 4a, 4b and the Slit shape can be the same on the individual levels Forming work to be distributed.
