  • Patent number: 6622539
    Abstract: In order to provide a deep-drawing method, with which a drawn part is arranged in a deep-drawing die between a first deep-drawing die part and a second deep-drawing die part and is formed by way of relative movement of the deep-drawing die parts in relation to one another, which—particularly for carrying out several consecutive drawing processes—is more time and energy saving than the known deep-drawing methods, it is suggested that a pressure variable with time during the drawing process be generated selectively at a limited pressure section of one of the deep-drawing die parts, this pressure pressing a section of the drawn part abutting on the pressure section against the respectively other deep-drawing die part.
