Capacitor can housing mfr. - forming rupture zone in metal housing by cutting lines into base using press tool

摘要

The capacitor housing (10) is cup shaped and is produced in an extrusion process. The centre section of the end is of increased thickness (16) and is used for electrode connection. A burst zone is formed (22) using a press tool (20) with a pair of inset cutting blades (40) which are parallel to each other. The blades are retained in slots by set screws (42). The capacitor housing is retained in a main block (18) and the blades are pressed into the surface until the required penetration depth is obtd. ADVANTAGE - Forms effective, reproducible burst zone.
