Fastgørelsesindretning med lav udsmednings-belastning

摘要

The anvil member (400) for a fastener installation tool comprises: a first end and a second end opposite the first end; a swage cavity extending between the first and second ends; an entrance section (414) located at the first end; a swage land (416) located adjacent to the entrance section (414) and having a first inner diameter (D1); and an inner bore (420) located adjacent to the swage land (416) and having a second inner diameter (D2). The swage land (416) is adapted to transmit a radially inward swage load applied by the anvil member (400), and the swage land (416) includes a width (418) that is smaller than a length (L) of the anvil member extending between the first and second ends thereof.
