Dies unit for deep-drawing tools for the optimization of drawing processes

摘要

Dies unit for deep-drawing tools with a predetermined product accuracy, in particular for drawn parts of high precision, characterized in that within a female dies base body (1) in balancing combination of the components clamping sleeve (2), pressure ring (3) and expansion of the blade element (4) is arranged, wherein during the drawing operation by reaction of the totally enclosed expanding element (4) in this case as an elastic compensating element is triggered, the reaction forces on the clamping sleeve (2) as compensation sleeve and thus on the product of the outside by knife, and thus an optimal automatic drawing gap - and deep drawing sheet metal inlet adjustment caused as a result of the ratio of sheet metal deformation forces is formed and as a result of the drawing gap optimized inner diameter with a highly accurate product frame up to the conventional fit is standard.
