    摘要: A method for the manufacture of a vessel bottom includes the following steps: after heating to a forming temperature a starting semi-product (1) of the cylindrical shape is placed on the centre of the female die (2), through the pressure of a first female die (3) the preliminary forging (1) is upset to a depth (h) to ensure the wall thickness (b) of a flattened segment (4), after the second heating to a forming temperature the flattened segment (4) is placed back into the same female die (2), the first male die (3) is replaced by a second male die (5), through the pressure of the second male die (5) the flattened segment. (4) is upset to the depth (h), the second male die (5) is released from a press ram and left pushed into the flattened segment (4), a sleeve (6) is put on the second male die (5), the sleeve (6) is pushed to the depth (h) for the creation - in collaboration with the second male die (5) - the area of the vessel bottom.
