Further, a long life is additionally ensured through the possibility of reworking the forming beam outlet surface in combination with effective protection of the diaphragm. According to the invention, the diaphragm is constructed as a radiation-impermeable layer which is enclosed up to its end faces by radiation-transparent material.
CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority of German application No. 10 2004 010.648.7, filed Feb. 26, 2004, the complete disclosure of which is hereby incorporated by reference.
OBJECT AND SUMMARY OF THE INVENTION On this basis, it is the primary object of the invention to overcome the problems relating to the above-mentioned diaphragm. A reduction in cost is achieved in particular through simpler and more economical manufacture and through increased life of the components that are used. Working life can be additionally increased by ensuring the ability to rework the forming beam outlet surface in combination with an effective protection of the diaphragm.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a radiation-transparent die half of a forming die, particularly a male die half (male die element) which will be described more fully and which is considered as an optical assembly in a very broad sense. The series of FIGS. 1 to 5 illustrates the production process.
Since the inner diameter of the hollow-cylindrical die half part 1 is manufactured with a slight difference in dimensions with respect to the smaller partial cylinder diameter, a gap remains open between the two die half parts 1, 2 for receiving radiation-impermeable material so that a radiation-impermeable layer 3 is formed inside the die half. This layer 3 is preferably constructed in such a way that the cylindrical die half part 2 in the area of the partial cylinder 21 with the smaller diameter is covered by a first radiation-impermeable cylindrical layer portion 31 which extends to the outside front surface 4 of the die half serving as beam outlet surface. A second radiation-impermeable annular layer portion 32 which is placed with its inner end face around the first layer portion 31 and is connected to the latter is located between the oppositely located surfaces of the two die half parts 1, 2. The two layer portions 31, 32 are preferably at an angle of 90� relative to one another and, according to the invention, form a diaphragm which is covered by material up to its end faces 33, 34 in that the layer 3 is situated between the hollow-cylindrical die half part 1 and the cylindrical die half part 2.
