Definitions
- the invention relates to a method for producing a hardened sheet metal profile from a blank or a semi-finished product according to the measures in Preamble of claim 1.
- DE 24 52 486 A1 counts a method for producing a hardened one Sheet profile from a board in a press hardening process for State of the art in which a circuit board made of hardenable steel heated to hardening temperature, then hot formed in a press tool and then cured while the sheet profile in the press tool remains. Since the sheet profile during the hardening process cooling is clamped in the press tool, receives to get a product with good dimensional accuracy.
- 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 openings in the Sheet metal profiles should serve as feedthrough holes for fastening screws. Such holes are also conceivable for the orientation of the sheet metal profile to be used in subsequent manufacturing operations.
- the prefabrication of the holes in the output board is disadvantageous. This is associated with additional manufacturing and logistics expenses. That too is Dimensional accuracy of the manufactured sheet metal profile depending on the pre-perforation posed. If the specified tolerances are left, that is Sheet profile unusable. Especially for sheet metal profiles with more complicated ones Geometries must be calculated with larger rejects in the cutting of the boards become.
- the hot forming and hardening in the press tool has due to the by combining the forming and tempering process in one tool rational way of working generally benefits. However, it can despite the restraint of the sheet profile in the tool due to thermal stress there is a delay in the component that cannot be predicted exactly. This can adversely affect downstream manufacturing operations. This can be remedied by reference points on the sheet metal profile, for orientation purposes of the sheet profile in subsequent manufacturing operations be used.
- the invention is therefore based on that known in the prior art Process based on the task, this rational and efficient to design and improve the manufacturing process of sheet metal profiles.
- this object is achieved in a method according to claim 1.
- This is individualized in that collar during the forming process in the press tool from unperforated areas of the Board are formed. There is no need to prepunch the boards. This complete work step in prefabrication can be omitted. hereby tool and labor costs are saved. Because the collar immediately can be created in the press tool, the blanks of the blanks or the semi-finished products are made independently of the collar. Also this leads to a rationalization of the procedure.
- a circuit board made of hardenable steel sheet is used as the starting product Commitment. This can already undergo a profile section that prepares the shape to have. Preformed sheet metal parts as semi-finished products can also be used according to the invention to be processed further.
- the collars created in the press tool in or on the sheet metal profile can as reference points for the orientation of the sheet metal profile in the following Manufacturing operations or for stiffening the sheet metal profile or as mounting holes serve.
- 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 (AI) 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 or semi-finished product made of sheet steel is heated 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 results in 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. In 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 collar is in shape embossed edges on the sheet profile.
- the collars serve as reference points for the orientation of the position Sheet metal profile in subsequent manufacturing operations. Using the reference points the sheet profile is picked up or aligned. This is from special advantage because it is formed due to the hot forming process Sheet profile can come to a delay that cannot be exactly predetermined. However, orientation can be ensured via the reference points to which the subsequent manufacturing operations are based. This also ensures consistent quality and reproducibility ensured in high volume production.
- the collar can also contribute to the stiffening of the sheet metal profile.
- An embodiment of the invention is also advantageous in practice The method of claim 3. Thereafter, the collars are used as penetrations generated in the sheet profile. Punching and putting through is practically done in one operation or in successive operations in the press tool.
- a pot-like shape can first be used to produce an extension be formed on the sheet metal profile, the bottom of which is then is separated out, as provided for in claim 4.
- Figure 1 shows a sheet profile 1 or a section thereof with an edge Collar in the form of an embossing that is raised upward in the image plane 2.
- the sheet profile 1 is made of an initially flat board 3 Made of sheet steel.
- the circuit board 3 is shown in FIG. 1 by the dashed line Line indicated.
- the board 3 in a hot-formed press tool at a hardening temperature between 700 ° C and 1100 ° C. Still clamped in the press tool the sheet profile 1 is then hardened by rapid cooling.
- the embossing 2 is produced on the sheet metal profile 1 Service.
- Such an embossing 2 on the edge of the sheet profile 1 serves as Reference point for the orientation of the sheet profile 1 in the following Manufacturing operations. It can be seen that the embossing 2 from the plane of the sheet profile 1 or the original board 3 protrudes.
- FIG. 2 shows a press tool 4 with a lower die 5, an upper punch 6 and a hold-down 7, the component (circuit board) fixed in the press tool 4.
- the stamp 6 is made after the forming process lowered from its upper starting position. At the decline of the stamp 6 is first a pot-like shape on the board or the resulting thermoformed sheet profile 8 generated.
- the die 5 is by the stamp 6, the sheet metal blank at the bottom 10 of the Forming separated.
- the passage 11 thus created in the sheet metal profile 8 serves as a reference point for alignment and Positional orientation of the sheet profile 8 for stiffening the sheet profile or as Mounting hole for the passage of a screw or the like.
- the sheet profile 8 is also clamped in the press tool 4 hardened.
- a blank is used 13 held in a lower die 14 by a hold-down device 15.
- the left half of the picture shows the starting position of the board 13 in the press tool 12 before the forming process.
- the board 13 through the top Hold-down clamp 15 and a lower punch 16 clamped.
- the lower Stamp 16 is located in the center of free-form space 17 of die 14.
- the hold-down device 15 is a cutting tool in the form of a perforated and through sleeve 18 guided displaceably arranged. This separates when using the hub of the press tool 12 conforming cutting process in the downward movement an opening 19 in the board 13 or the one produced therefrom Sheet profile 20. Simultaneously with the downward movement of the cutting tool 18 the edge-side regions 21 of the opening 19 changed over like a collar and so creates an extension 22 in the sheet profile 20.
- the section shown in Figure 3 from a sheet metal profile 8 and 20 shows an extension 12, 22, as in a procedure according to the Figures 2 and 4 described, has been generated.
- the reference points are used to record and orient a sheet profile 8, 20 in cutting operations, for example laser cutting, joining operations etc. used. Also for coordinate-based recording and Adjustment of the sheet profile 8, 20 in numerically controlled systems can the reference points are used.
- the penetrations 12 and 22 can also be used for stiffening or serve as mounting openings in the sheet profile 8, 22.
