METHOD OF FORMING HEADER EXTENSION, AND VEHICLE STRUCTURE |
摘要 |
A method of forming a header extension coupling a front header and a roof side inner includes: electrically heating a part of a material to a temperature of not less than a hardening temperature such that a front header side is heated to the temperature of not less than the hardening temperature and a roof side inner side is heated to a temperature of less than the hardening temperature; and press-forming the material after the electrical heating into the shape of the header extension; and hardening the material by quenching. In this way, a vehicle structure can be provided such that the bending mode under application of a load to the roof can be appropriately controlled, and productivity can be improved. |

1. A method of forming a header extension connecting a front header and a roof side inner comprising:
electrically heating a part of a material to a temperature of not lower than a hardening temperature thereof such that a front header side is heated to the temperature of not lower than the hardening temperature and a roof side inner side is heated to a temperature lower than the hardening temperature; and press-forming the material after the electrical heating into a shape of the header extension and hardening the material by quenching. |
