ABSTRACT:
This invention relates to a swaging machine which preferably comprises depth-setting wedges which are adapted to be inserted parallel to the axis of the machine between the swaging dies and the die-actuating rams associated with said dies and which permit the use of the machine for recess swaging. Each die and the die-actuating ram associated with said die have parallel bores and a U-shaped spring is inserted into said bores to connect said die and ram. This arrangement will ensure that the opening defined by the dies will be held open even if a machine provided with such depth-setting wedges operates at a low speed or is at a standstill.
