Abstract
1,225,930. Making fastenings; stamping; tube expanding; work supports. M. LACHAUSSEE, and A. MAIGRET. 9 Oct., 1969 [20 Dec., 1968], No. 49623/69. Headings B3A, B3J, B3Q and B3W. A method of making metal parts, e.g. pressstuds and tubular rivets, comprises stamping metal strip to form a cup-shaped blank, separating the blank from the strip, re-inserting the blank into the space it occupied in the strip so that it is held by the strip, executing one or more further forming operations on the blank held by the strip and expelling the finished article. After forming the cup-shaped blank, the strip 2, Fig. 2, is advanced to carry the blank 1 beneath a punch 3 which is surrounded by a hold-down 13 and co-operates with a die 4 to sever the blank. A support 5 biased by a spring 6 re-inserts the blank when the punch is raised, Fig. 3 (not shown). At the next workstation, Fig. 4, a bead 1b is formed on the blank by an expanding die, the finished article being ejected from the carrier strip by a sliding finger at the next station. The strip may be formed with several rows of blanks. Pressstuds with metal rings 10, Fig. 7, or rivets (12), Fig. 9 (not shown), may be formed from the carrier strip, the rings 10 or second parts (11) of the studs being secured by folding over the edge of the blank.
