Abstract
The present invention relates to methods and apparatus for forming features on an elongated metal wire and, in particular to making features, such as pin tips, compliant sections and retention sections on electrical terminal pins for use in interconnecting electrical leads, plated through holes in printed circuit boards and/or connector contacts.
Claims14
A method for forming a feature on an elongated metal wire, comprising:
- rotating a ring about a tool guide in a first direction, the ring connected by links to a first forming tool, a second forming tool, a third forming tool and a fourth forming tool causing the first forming tool and the second forming tool to slide in a first slot in the tool guide towards a first pair of distal sides of the wire;
- simultaneously stamping the first pair of distal sides of the wire between a working end of the first forming tool and a working end of the second forming tool such that the working ends press into the first pair of the distal sides a first distance;
- rotating the ring about the tool guide in a second direction moving the links to slide the third forming tool and the fourth forming tool in a second slot in the tool guide towards a second pair of distal sides of the wire and moving the links to slide the first forming tool and the second forming tool in the first slot away from the wire;
- simultaneously stamping the second pair of distal sides of the wire between a working end of the third forming tool and a working end of the fourth forming tool such that the working ends press into the second pair of the distal sides a second distance;
- rotating the ring about the tool guide in the first direction moving the links to slide the first forming tool and the second forming tool in the first slot towards the first pair of distal sides of the wire and moving the links to slide the third forming tool and the fourth forming tool in the second slot away from the wire;
- simultaneously stamping the first pair of the distal sides of the wire between the working end of the first forming tool and a working end of the second forming tool such that the working ends press into the first pair of the distal sides a third distance;
- rotating the ring about the tool guide in the second direction moving the links to slide the third forming tool and the fourth forming tool in the second slot in the tool guide towards the second pair of distal sides of the wire and moving the links to slide the first forming tool and the second forming tool in the first slot away from the wires;
- and
- simultaneously stamping the second pair of distal sides of the wire between the working end of the third forming tool and the working end of the fourth forming tool such that the working ends press into the second pair of the distal sides a fourth distance,
- whereby the feature is formed in the sides of the metal wire.
