Definitions

  • the invention relates to a component subject to internal pressure, in particular for fuel injection systems, consisting of an elongated tubular body with a longitudinal bore and at least a cross hole with connecting parts for supply and discharge.
  • accumulator injections common rail
  • components subject to internal pressure are necessary.
  • Such components are used for high-pressure accumulators (rails) and injectors.
  • the object of the invention is to further increase the strength to create in particular in the area of drilling intersections.
  • the solution principle of the task is instead of a conventional one cylindrical cross section known from the prior art a non-cylindrical cross section for the longitudinal bore to use and apply a process about plastic deformation, to make such a cross section.
  • a major advantage of the invention is that in particular for forged components subject to internal pressure where the connections with the cross holes on the elongated Bodies are forged to deform in such a way that from the cylindrical cross section produced by deep hole drilling a non-cylindrical cross section is created in the longitudinal bore.
  • suitable supports level or V-shaped support
  • suitable supports for example, that an elliptical Cross-section arises, also in the intersection area non-cylindrical cross sections arise and thus load voltages, which especially in these areas due to the high pressures arise, be minimized.
  • the component to heat either partially or in its entirety in order to to enable such an upsetting in a simple manner.
  • Fig. 1 is an internal pressure loaded component 1 in the form of a Common rails shown.
  • This component 1 has an outer contour 2, and a connecting part 3 adjoining the outer contour.
  • This connecting part 3 additionally has a transverse bore 4, that in an intersection area 5 with that within the internal pressure Component arranged longitudinal bore corresponds.
  • the longitudinal bore 6 points in its original (in the drawing not shown) state a circular, cylindrical Cross section on.
  • the internal pressure loaded component is preferably as whole completely heated and supported on a level 7, against which pushes a force F.
  • force F causes the outer contour of the component subjected to internal pressure expands in the direction of R1 and R2 and so does the corresponding cylindrical cross section of the longitudinal bore 6 depending the magnitude of the force F is elliptical.
