Multi-element die system, a die for drawing a large and complex element and method for production of the die

摘要

The object of the invention is a multi -element matrix system, a matrix for the extrusion of a large and complex element and the way the matrix is produced.A multi -element matrix system consisting of a base plate on which the elements of the matrix are embedded is characterised by a matrix (2) composed of several elements (3, 4, 10, 11, 12, 13, 14,15, 16 and 17), each of which has two overflow openings (5) and overflow openings (5) are positioned opposite the openings (5) in the base plate (1),and in the transition holes (5) and the holes (5) in the base plate (1) the fixing straps (6) are fitted and each matrix element (2) has at least two graduated gaps (7) for the fixing strapsb (8) joining the elements (3, 4, 10, 11, 12, 13, 14, 15, 16 and 17) of the matrix (2) with the base plate (1).The matrix for extruding and extruding a large and complex element, especially from a sheet, made of many elements, is characterized by being made of elements (3, 4, 10, 11, 12, 13,14, 15,16 and 17) for extruding and curing deposited on the base plate (1) by means of transient openings (5) and fixing of shafts (6) and fixed by means of fixing screws (8) deposited in:Graduated holes (7) in the elements (3, 4, 10, 11, 12, 13, 14, 15, 16 and 17) of the matrix (2) and in threaded holes (18) in the base plate (1).
