Abstract

1423671 Upsetting; making hinge pins ED SCHARWACHTER KG 19 Feb 1973 [21 Feb 1972] 8029/73 Headings B3H and B3A [Also in Divisions E1-E2] A hinge pin is produced from bar stock 2, 21 by feeding the stock either to a set of tools 3, 5, 6 for sequential operation on the bar stock and shearing the blanks therefrom or to a set of tools, Fig. 2, for shearing of a blank 20 from the stock and upsetting. The tools produce a head 19, 28 or an intermediate enlargement on the blank. In the first embodiment an embossing tool 3 of an eccentric press notches the bar stock and knurls the head 13. The blank is separated from the stock by a shearing tool 6 operated by the same platen 15 of the press as the tool 3. The head has an oval or polygonal cross-section. In the second embodiment the head is produced by an upsetting punch 29, Fig. 2, operating on a blank 20 in a die 25. The initial bar stock is fed to the deforming and shearing tools by straightening rollers 8, 23. The bar stock has one or more axial grooves (33), Figs. 3 and 4 (not shown), and if the head is oval its major axis may be perpendicular to or parallel to the line between the grooves if the stock has two grooves. The head may be knurled (44), Figs. 5 and 6 (not shown), or be provided with notches (42), Fig. 7 (not shown).
