Definitions

  • the invention relates to a method for producing a large sheet metal part, in particular a body component for a vehicle from a flat circuit board according to Preamble of Claim 1. Such a method is known from the DE 19717953 A known.
  • Deep drawing takes place in hydraulic or mechanical Drawing presses instead.
  • a flat, trimmed sheet metal part, the board is in a conventional forming tool is inserted and stretched and compressed into one Formed hollow body.
  • large sheet metal parts manufactured in this way shown that they are particularly in the case of slight curvature in a central area of their Area extension are relatively soft and have only a low buckling stiffness there.
  • Hydromechanical deep drawing (Hydromec process) is also used to manufacture sheet metal parts. known. With these processes, no die is required, rather the press Pull the clamped board into a one filled with an active medium (water) Vessel that replaces the die. The water pressure causes the sheet to form of the drawing die.
  • the clamped Blank pre-stretched before the actual shaping process to a to achieve increased ironing and thus increased strengthening in the middle of the sinker.
  • the object of the invention is a method for producing a large area To create sheet metal part from a flat board, which with increased buckling stiffness in the Short cycle times of the sheet metal part enabled in the middle of the board.
  • the main advantages achieved with the invention are the fact that by combining two known processes for the first time, namely the stretching of one First, level the circuit board using the active medium to achieve strain hardening in the middle of the board and the conventional pressing (deep drawing) of sheet metal parts Advantages of both processes - optimized component behavior and high process effectiveness - come to fruition.
  • the pre-stretched sheets can be produced on systems with relatively low clamping forces as the maximum pressures required are approx. 15 bar. Even mechanical Presses can be used.
  • the well-known hydromechanical Finished molds require high pressures, which in turn lead to high press clamping forces lead are not necessary in the method according to the invention, since the final molding done here conventionally. Because the stretching in contrast to the hydromechanical Finished molds take up little time, the cycle time at The inventive method significantly reduced.
  • pre-stretched sheets are in a linked press line as first operation imaginable.
  • the semi-finished product Pre-stretched blanks (comparable to tailored blanks) at the press shop to be delivered.
  • tailored blanks are also for further weight reduction conceivable.
  • a solidification e.g. in the area of the thinner sheet local increase in buckling stiffness can be used (example Base plate / tunnel / bottom plate).
  • Pre-stretched boards can also be found in soft tools commonly used in prototype manufacturing Find use, be used. So far it was not possible because of the high Occurring pressures of hydromechanically manufactured parts using so-called soft tools reshape.
  • the method according to the invention can increase component rigidity again a clear weight reduction potential through the use of thinner Sheet metal offers can be achieved without the previous disadvantages of hydromechanical shaped sheets - very high process cycle time and high system costs - in purchase to have to take. It can be the conventional sheet metal forming processes achieve comparable cycle times. A separate production of the preformed blanks e.g. can be carried out at the semi-finished product manufacturer. So it is also a commitment for Prototype components possible with almost no cost.
  • a body part For a vehicle first cut or punch a plane Board 2 created. This board 2 is then inserted into a forming tool 3, which consists of a fixed lower part 4 and an upper movable die 5 composed. Connected to the die 5 are spaced apart Hold-down device 6 which, when the forming tool 3 is closed, against the top of the Press board 2 and thus position it correctly in the forming tool 3.
  • a forming tool 3 which consists of a fixed lower part 4 and an upper movable die 5 composed.
  • Hold-down device 6 Connected to the die 5 are spaced apart Hold-down device 6 which, when the forming tool 3 is closed, against the top of the Press board 2 and thus position it correctly in the forming tool 3.
  • the cavity 7 there is a cavity 7 in the lower part 4 adjacent to the circuit board 2 provided for an active medium 8.
  • the cavity 7 has an inlet or outlet 9 provided for the active medium 8.
  • a liquid is preferably used as the active medium 8 (Water, oil or the like) is used.
  • the active medium 8 could also be pneumatic be trained (e.g. air).
  • the die 5 has a profiled on its underside Shape up.
  • the pre-stretched, profiled Preform 10 removed from the forming tool and into a conventional one multi-part deep-drawing tool 11 inserted and there in a deep-drawing process in the Formed end shape 12.
  • the deep drawing tool 11 comprises a fixed lower part 13 with an insert 14 which determines the final shape 12, a movable upper part 15 and Hold-down device 16.
  • the circuit board 2 can have one over the entire area have constant wall thickness; however, the board 2 can also be used as a tailored blanks component be trained.
