摘要:
In a method of applying a firmly adhering metallic coating onto a profiled structure of steel sheet, a profiled structure of steel sheet is fogged in with metal powder in a treatment chamber. The metal powder is deposited electrostatically across the surface of the profiled structure. The profiled structure is then subjected to a heat treatment for realizing a coating as a consequence of a diffusion process between the steel sheet and the metal powder. Subsequently, the profiled structure is cooled down.

A dashboard for a motor vehicle includes a support beam extending between windshield pillars of a motor vehicle body, and an active arrangement which interacts with the support beam for vibration damping. The active arrangement includes plural actuators which are disposed on the support beam and a controller which is operatively connected to the actuators. Further provided is an alert system for recognizing a fatigue state of a driver, with the actuators operatively connected to the alert system via the controller.

A tiered furnace includes a plurality of decks in superimposed disposition for receiving flat or at least partly shaped plates which are made of steel. Each of the decks has at least one heater to thereby provide each deck with at least two heating zones that are operating at different temperatures.

An automobile column, for example an A-column, a B-column, a C-column and/or a D-column, is made of sheet steel. The automobile column has a first region which underwent heat treatment, a second region which is not heat-treated, and a transition zone between the first and second regions. The transition zone is hereby defined by a width which is smaller than or equal to 50 mm.

A thermoforming press for forming and hardening metal sheets includes an upper die and a lower die. At least one of the upper and lower dies has a mold jaw and a support jaw which are movable relative to one another between a first position in which the support jaw rests against the mold jaw to block a flow of coolant between the mold jaw and the support jaw, and a second position in which the support jaw is spaced from the mold jaw by a distance to define a cooling gap for coolant to flow between the mold jaw and the support jaw.

A heating device and a heating method which is able to quickly and accurately partition each region of a material to be heated and heat up each of the region to a required temperature, and a shape and required temperature of each region is different from each other. A heating device for heating a material to be heated by applying an electromagnetic wave to the material, wherein a plate member(s) which shields, absorbs and/or reflects the irradiated electromagnetic radiation and has a predetermined pattern contour can be placed, at least partially, close to the material to be heated.

A method for making a vehicle body component includes forming a generally flat plate of unhardened, hot-formable sheet steel with a marginal shape which corresponds essentially to the developed configuration of the finished vehicle body component. The formed plate is hot-formed and hardened in a single press tool to define a sheet profile which corresponds to the configuration of the finished vehicle body component, and a surface coating is applied to the sheet profile.

摘要:
In a method for press-hardening a metallic formed structure made of a hardenable steel sheet, the steel sheet is heated above a transition temperature Ac3 and then placed in a cooled press having a forming tool with at least one uncooled contour section for forming a region of reduced hardness. Marginal regions of the steel sheet are clamped with a sheet holder arrangement which has an inner sheet holder and an outer sheet holder. The inner sheet holder is hereby located closer to the forming tool than the outer sheet holder. The sheet holder arrangement is configured to slow down flow of the marginal regions into the forming tool. After closing the press tool, the steel sheet is formed in a first forming phase by holding the marginal region with the outer sheet holder and in a subsequent forming phase by holding the marginal region with the inner sheet holder.
