Abstract

A forming die includes a base and at least two die segments. At least a first one of the die segments is moveably mounted to the base for shifting between closed and opened positions. The die segments together define a cavity having an opening when the first die segment is in the closed position. A punch is moveably mounted to the base for shifting between a retracted position and an extended position wherein the punch crimps a part positioned within the cavity. A powered actuator is connected to at least the first one of the die segments, and shifts the first die segment between the closed and opened positions such that a part positioned within the cavity can be removed after crimping by shifting of the first die segment to the open position. The forming die is particularly well-suited for crimping electrochemical cells.
