Abstract: A determination part determines whether or not a shadow of an upper mold is expanded to a photodiode by laser beam projected to a light receiver side based on a light receiving state of a photodiode positioned in a vicinity of the upper mold. When it is determined that the shadow of the upper mold is expanded to the photodiode positioned in the nearest vicinity of the upper mold, the invalidation unit invalidates the photodiode. A detection unit detects a presence or absence of a foreign body between the upper mold and a lower mold based on light receiving states of the effective plurality of photodiodes during a lowering operation of an upper table.

Abstract: A swage tool includes a power unit connected to a yoke. The power unit exerts vertical force on a die block. The yoke holds swage dies in place and opposes the force exerted by the die block. The die block transfers the load exerted by the power unit into the swage dies, which surround the connector. The swage dies convert vertical force from the power unit into a radial swage on the connector. Quick release endplates hold the swage dies in place in the yoke and the die block. A yoke shroud keeps broken pieces of the yoke together if the yoke fails. A counter records the number of swages made by the tool. A rotating handle, a stand, remote wireless actuation and swage die identification imprints are also provided.
