METHOD FOR PRODUCING A MOTOR VEHICLE COMPONENT FROM ALUMINUM |
摘要 |
A method for producing a motor vehicle component is disclosed having the steps of providing a strain-hardened blank composed of a 5000 grade aluminum alloy, partially heating the blank in a first region to a temperature higher than 350° C., in particular higher than 400° C., and in a second region to a temperature between 150° C. and 350° C., preferably to 300° C., in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, and transferring the blank into a cooling tool, and performing cooling in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s. |

1. A method for producing a motor vehicle component, in particular a motor vehicle pillar, characterized by the following method steps:
providing a strain-hardened blank composed of a 5000 grade aluminum alloy, partially heating the blank in a first region to a temperature higher than 350° C., in particular higher than 400° C., and in a second region to a temperature between 150° C. and 350° C., preferably to 300° C., in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, transferring the blank into a cooling tool, and performing cooling in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, generating a yield strength in the first region of less than 250 MPa and greater than 120 MPa, and a yield strength in the second region of less than 450 MPa and greater than 200 MPa. |
