Method and device for manufacturing a piezo-electric actuator module with an encased piezo actuator and a piezo actuator module

摘要

The method involves clamping piezo actuators (40) between a metallic actuator head (42) and a metallic actuator base (41), where the piezo actuators are provided with a casing (43) that is fastened to the actuator head, the actuator base and/or to the piezo actuator. Fastening of the casing takes place by an external application of a metal portion (44) that encloses the casing. The fastening takes place by pressing of the metal part using an electromagnetic forming process. Independent claims are also included for the following: (1) a device for the production of a piezo actuator module (2) a piezo actuator module.
