Die Erfindung betrifft eine Umformvorrichtung (10) zum Erzeugen von Verbindungsansätzen (16) an Verstärkungselementen (14), aufweisend wenigstens eine Druckwellenerzeugungseinrichtung (18) zum Erzeugen wenigstens einer auf eine erste Breitseite (44) eines Verstärkungselements (14) gerichteten Druckwelle, sowie eine an einer der ersten Breitseite (44) gegenüberliegenden zweiten Breitseite (46) des Verstärkungselements (14) anzuordnenden Maskeneinrichtung (20), wobei die Maskeneinrichtung (20) mit einem Formblock (30) ausgebildet ist, der zum Erzeugen vorbestimmter Verbindungsansatzformen geformte Ausnehmungen (28) aufweist.
摘要:
The invention relates to a method for the high-pressure-tight connection of at least one plate-shaped body (1, 2) to a further body of a fuel injector, wherein a clamping sleeve (3) is used by means of which the bodies (1, 2) to be connected are axially clamped with respect to each other. According to the invention, a holding body (4) interacting with the clamping sleeve (3) is used as a further body, having at least one groove (5) that is arranged on the outer circumference and configured peripherally in a radial plane. The method further comprises the following steps: Fixing the holding body (4), applying the at least one plate-shaped body (1, 2) and coaxially aligning the bodies (1, 2, 4) to be connected, joining the clamping sleeve (3) via the bodies (1, 2, 4) to be connected, stretching the clamping sleeve (3) by applying an axial force such that tension is generated in the clamping sleeve (3), producing a positive connection between the clamping sleeve (3) and the holding body (4) during stretching by using a high-speed deformation method, wherein the positive connection is effected by deforming the clamping sleeve (3) in the region of the groove (5) and relieving the clamping sleeve (3). The invention further relates to a fuel injector.

With the invention, it is intended to improve a method and a device for explosion forming of workpieces, wherein at least one workpiece (5) is arranged in at least one die (2) and is formed by means of an explosive agent (8) which is to be ignited, in such a way as to provide a technically easy-to-handle ignition mechanism with the shortest possible setting-up times, which ignition mechanism permits as precise an ignition of the explosive agent (8) as possible with repeatable accuracy. Said object is achieved by means of a method and a device in which at least one workpiece (5) is arranged in at least one die (2) and is formed by means of an explosive agent (8) which is to be ignited, in which the explosive agent (8) is ignited by means of induction.
