Definitions

  • Workpieces with cross sections are in shape under "rotationally symmetrical" of circles and regular polygons such as hexagonal and octagonal profiles to understand.
  • the workpiece outer surfaces can be in the axial direction straight, conical, domed (barrel-shaped) or graded. Such workpiece surfaces can be trained accordingly the - preferably exchangeable - press jaws taken into account become.
  • a special area of application for which the subject of the invention the combination of high-strength metal is particularly suitable (e.g. steel) existing hose fittings with flexible hose lines.
  • the hose line consists essentially of one Hose piece, over the ends of which thick-walled compression sleeves are pushed become. Nipples are plugged into the ends, with fittings are provided, e.g. those with internal or external threads, flange plates, Pipe bends, elbows, pipe branches etc., which from the Protrude hose ends.
  • the inner parts support the hose walls during the Pressing process from the inside.
  • the compression sleeves are the shell diameters from the press jaws to the desired Final diameter reduced, but not only large press paths are to be covered, but also the pressing forces increase progressively.
  • the pressing processes in small and large series production must be included high dimensional and repeat accuracy because the Hose lines, the pressures up to 1000 bar (100 MPa) and above have to endure, very often are safety-relevant components, their failure and failure cause immense costs and environmental damage can, and last but not least, people are at risk.
  • hose lines due to the constant progress of Technology is becoming more complicated to shape.
  • Increasingly compact machines and systems that are in progress reduce the installation volume of Hose lines, so that their designers are always new See problems confronted in the narrowest spaces and in accordance with regulations install properly functioning hose lines.
  • Modern Computer-controlled bending machines are an essential part of this Become help if it makes complicated, quick, precise and inexpensive Multi-bend pipe bends are economical even in small series can be produced.
  • the pipe bends can also be act those that have a bending angle of 180 degrees with the smallest possible Possess bending radius. Such bending radii are the same, for example the pipe diameter.
  • the constriction path i.e. the diameter difference and after pressing
  • the constriction path is divided into only four compression zones, which are between the pressing surfaces of the press jaws.
  • the material of the compression sleeve in these areas so compressed that their Wall thickness increases. This growth can only be done internally, because the closing press jaws grow outwards prevent.
  • the local compression in four-jaw systems often so large that the inner tube material including it Textile or steel reinforcement is destroyed.
  • the Compression path on the circumference is calculated from the press path x 3.14, is 25.12 mm in both cases. Spread over four compression zones This results in 6.28 mm per compression zone, distributed over eight compression zones this results in only 3.14 mm per compression zone.
  • the synchronization takes place in that the four inner press jaws on their outer End in a mirror-symmetrical arrangement depending on their direction of movement have two control surfaces with an opening angle of 135 degrees, and that the outer control body on their inner sides two complementary thereto Have control surfaces. Due to the lateral drive of the outer Control bodies can not large because of their tendency to tilt radial pressing forces are generated and transmitted. This press die is above all not divisible, so that no complicated shaped and / or bulky workpieces can be inserted.
  • EP-A-0 539 787 describes a pressing tool as described at the beginning Genus with outer and inner control bodies known, that too has eight pressing surfaces, so that a significantly more uniform pressing process with reduced edge pressures.
  • the planes of symmetry two of the inner control bodies run in the direction of the press stroke and the planes of symmetry of the other two internal control bodies perpendicular to this. This covers the last two inner control body a possible parting line of the press tool, the consequently, it is also not divisible. Such a division that the Bulky hose fittings would be impossible to insert described, still planned or possible.
  • the Press stroke in a ratio of 1: 1 to the radial inward movement the pressing surfaces is transferred, so that a corresponding strong press drive is required.
  • DE-C-19814 474 is also a pressing tool at the beginning described genus known, which has eight pressing surfaces, so that a significantly more uniform pressing process with reduced edge pressures he follows.
  • the control surfaces of the two outer, in the stroke direction of the Press drive movable control body are angled several times formed, and two transverse to this inner control body have been replaced by four pressure pieces, the pairs above and are arranged below a parting line to two tool halves create that can be spread far apart to insert to allow bulky hose fittings.
  • This design requires but with a variety of intricately shaped moving parts numerous sliding surfaces that must be machined to a high quality. Out of it there are corresponding manufacturing costs.
  • the press stroke in a ratio of 1: 1 to the radial Inward movement of the pressing surfaces is transmitted, so that a corresponding strong press drive is required.
  • the invention is therefore based on the object of a pressing tool Specify the type described above, the lower driving forces required, is simpler in construction and a lower number of high quality has to be machined sliding surfaces, so that it can be manufactured more cost-effectively is. Furthermore, the conditions are to be created for that the pressing tool in special cases also bulky for insertion Hose fittings or other bulky workpieces can be divided.
