Definitions
- the invention relates to a method for producing a hardened sheet metal profile from a possibly preformed board.
- the term circuit board is subsequently uniform for both a flat steel plate and also used for a preformed semi-finished product.
- DE 24 52 486 A1 counts a method for producing a hardened one Sheet metal profile from a board in a press hardening process for State of the art.
- a hardenable steel Board heated to hardening temperature, then warm in a press tool formed and then hardened while the sheet profile in Press tool remains. Because the sheet profile during the course of the hardening process cooling is clamped in the press tool you get a product with good dimensional accuracy.
- the hot forming and hardening in the press tool is due to the combination of forming and tempering processes in one tool rational way of working.
- WO 99/07492 provides for the above-described press hardening process to modify and the edge areas in the press tool bend from prefabricated holes so that collars are formed.
- the holes are bent in the press tool before hardening.
- the openings in the sheet metal profile are intended as through holes for fastening screws serve. It is also common in the prior art to use such Openings referred to in technical terms as passages as reference holes or recordings for the precise alignment of the sheet profile to be used in subsequent processes. They also serve as assembly clearances or as a stiffening measure.
- the object of the invention is based on the prior art based on a process for the production of hardened sheet metal profiles more economically and make it more rational.
- the formations can have any shape. For example, you can be round or oval.
- pot-like formations are made before the hot forming process tool wear in the compensation tool is less.
- the production of the pots in a preforming tool also means that Shaping possibility much larger.
- One can be in the preforming tool pot-like shape can also be produced in several stages. All in all the manufacturing costs are reduced.
- the sheet profile can be used in subsequent processes based on the formations as reference points can be recorded and is precisely positioned.
- the formations can also be used to stiffen the sheet profile serve.
- a particularly advantageous procedural measure sees according to claim 2 before that a final shaping calibration in the press tool the molding takes place.
- the shape is on it in the press tool brought exact exact measure. Then the hardening process begins.
- the cooling performed here is the sheet product in the press tool clamped.
- a blank or semi-finished product made of steel is preferably used, which is expressed in percent by weight of carbon (C) 0.19 up to 0.25, silicon (Si) 0.15 to 0.50, manganese (Mn) 1.10 to 1.40, titanium (Ti) 0.020 to 0.050, boron (B) 0.002 to 0.005, aluminum (Al) 0.02 to 0.06 as well Phosphate (P) in a proportion up to max. 0.025, sulfur (S) max. 0,015, Chrome (Cr) max. 0.35 and molybdenum (Mo) max. 0.35, with the rest iron (Fe) is inclusive of melting-related impurities.
- the blank provided with one or more formations is heated in the heat treatment system to the hardening temperature, that is to say to a temperature above Ac 3 , where the steel is in the austenitic state. As a rule, this temperature is between 775 ° C and 1000 ° C. Then the forming process takes place in the press tool, whereupon the hardening begins by cooling. This creates a fine-grained martensitic or bainitic material structure.
- the sheet profile is clamped in the press tool during the hardening process.
- the cooling performed here can be carried out directly or indirectly. With direct cooling, the sheet profile is brought into direct contact with a coolant. With indirect cooling, the press tool or parts thereof are cooled.
- the floor a shape in the press tool is cut out. This can through an appropriate design of the stamp of the press tool respectively.
- the bottom is then torn out.
- a shape is preferably produced in which the dimensions of diameter and depth in a ratio of 2: 1 are as claimed 4 provides. Formations are considered to be advantageous in practice with a diameter of at least 20 mm and a depth of approx. 10 mm.
- the sheet profile can be trimmed in subsequent operations (claim 5).
- the pot-like formations can be trimmed here.
- the sheet profile itself can also be subjected to cutting operations become. If the formations are no longer required and in the waste area of the sheet metal product, you can remove them yourself.
- Figure 1 shows a sheet steel plate 1, in which a pot-like shape 2 is made.
- the formation of the formation 2 takes place on the Sheet steel 1 before the forming process and the tempering process.
- the circuit board 1 is heated to the curing temperature, ie to a temperature above Ac 3 . Depending on the steel, the temperature is set between 700 ° C and 1,100 ° C. The steel is then in an austernite state.
- the board 1 is then formed in a press tool 3 to the sheet profile 4.
- the press tool 3 has an upper die 5 and a lower die 6. In the lower die 6 there is a die 7 which is matched to the contour of the pot-like formation 2, whereas a corresponding stamp insert 8 is provided in the upper die 5.
- the formation 2 is calibrated in the press tool 3, ie brought to its final exact size. In this case, only a slight final shaping takes place on the formation 2.
- the sheet profile 4 is then clamped in the press tool 3 and then hardened by rapid cooling.
- Figures 2 and 3 show a pot-like shape 2 in a sheet metal profile 4.
- the formation 2 has a depth t in the example shown here of 10 mm and has an average diameter d of 20 mm.
- the Formation 2 tapers below with an angle ⁇ of approximately 10 ° or greater. This ensures that the sheet profile 4 from the press tool 3 can be removed easily.
- the rejuvenation of the shape 2 also ensures that the sheet metal profile 4 is easy in subsequent operations and can be recorded true to position using the shape 2.
- the shape 2 can be used both as a reference pot and as a reinforcement shape serve on the finished component.
- stamp insert 8 can Calibrate the advanced shape 2 whose base 9 is cut off or be ripped out. In this way, an extension is obtained.
- the Torn out soil 9 can through a scrap discharge channel 10 in the lower die 6 are dissipated.
