JPS5570435A - Automatic producing apparatus of conduction terminal - Google Patents

Abstract

PURPOSE: To voluminously produce conduction terminals inexpensively without requiring labor by so arranging the apparatus that the terminals whose four faces at both end parts are made finer toward the respective ends and the terminals having flat parts are automatically produced by using wires of square form in section with one unit of machine.

CONSTITUTION: In the device of intermittently feeding the wire A of a square shape in section passed thereonto with a wire support rod 22 by a length for one conduction terminal for each one rotation of a prime moving wheel 15, the wrapping terminals whose both end parts of the square shape in section are made finer respectively toward the ends are automatically produced by repeating the operations of stamping the concave groove parts a of longitudinally straight crest form in the respective centers of the both right and left side faces of the wire A by left and right drive die rods 39, 40 and the concave groove parts b of horizontally straight crest shape by upper and lower drive die rods 97, 117, respectively, connecting said concave groove parts a, b to square- form concave grooves, and cutting the center of the concave grooves thereby forming the terminals A, A' having the tapered reduced parts C at the four faces on both ends. In the similar manner, the connector pins having flat concave parts D are also produced by using left and right pressure driving die rods 41, 42.
