FORMING PROCESS FOR HOT FORMING A STEEL SHEET OF A ROTOR BLADE TO BE PRODUCED FOR A WIND ENERGY PLANT

摘要

The present invention concerns a forming process for hot forming of a steel sheet of a rotor blade to be produced of a wind power installation, including the steps heating the steel sheet in a furnace while the steel sheet is lying on a hearth bogie, displacing the heated steel sheet with the hearth bogie from the furnace into a pressing apparatus for the hot forming operation, transloading the heated steel sheet in the pressing apparatus from the hearth bogie on to a form bogie having a counterpart form and pressing the steel sheet by at least one pressing punch which presses on the steel sheet in such a way that it is formed between the pressing punch and the counterpart form and in particular assumes the shape of the pressing punch and the counterpart form.
