Description

Wynalazek dotyczy sposobu wzmacnia¬ nia obrzezy dolnych czesci zatrzasków, tak zwanych czesci sprzegajacych. Obrzeza te dotychczas wyrabiano w postaci Walka (fig. 1), zapomoca wtlaczania dolnej czesci1 zatrzasku, wysoko wyciagnietym brzegiem 2 (fig. 2), do wykiroju 3 (fig. 3) w pod- tloczee.Ten rodzaj wyrobu stawal sie przez to drozszym, ze kazda dolna czesc zatrzasku wykrawana byla pojedynczo z paska bla¬ szanego, nastepnie zostawala do niego przy¬ ciskana i dopiero wtedy wprowadzana do wykroju 3 (fig. 3) specjalnego narzedzia przymykajacego, w nalezytej pozycji.^Stosownie do niniejszego wynalazku po- grubienile obrzeza 4 (fig, 4), osiaga sie przez to, ze czesc blachy 5, przed wykrojeniem dolnej czesci zatrzasku z patska blaszanego, stosownie do fig, 6, zostaje w ten sposób pogrubiona, ze po wykrojeniu gotowego ka¬ walka (dolnej czesci zatrzasku) jest on mocniejszy, niz blacha uzyta do jego wyrobu.Filg. 7 przedstawia pasek miaterjalu z którego, odpowiednio do stopniowego wy¬ twarzania, wyrabia si^ dbllne czesci ziatnza- sków 8 z wysoko wyciagnietym brzegiem 5, dalej dolne czesci1 zatrzasków 9 z pogrubio¬ nym juz brzeg|iem 4, ii wreszcie otwory wy¬ krojone 10, które pozostaja w pasku ma- terjalu po wykrojeniu dolnych czesci za¬ trzasków.Fig. 8 przedstawia rzut poziomy czesci paska stosownie do fig. 7. PLThe invention relates to a method of reinforcing the periphery of the lower parts of the latches, the so-called coupling parts. Until now, these edges have been manufactured in the form of a roll (fig. 1), by pressing the lower part of the latch, with the highly extended edge 2 (fig. 2), into the cut 3 (fig. 3) in the backing. that each lower part of the clasp was cut individually from the bleached strip, then pressed against it and then inserted into the blank 3 (Fig. 3) of the special stopping tool, in the correct position. periphery 4 (Fig. 4), it is achieved that a part of the sheet 5, before the lower part of the clip is cut out of the sheet metal tab, according to Fig. 6, is thickened in such a way that after the finished cylinder is cut out (the lower part of the clip ) it is stronger than the sheet metal used for its production. 7 shows a strip of material from which, according to the gradual production, the distal parts of the lattices 8 are produced with a highly extended edge 5, then the lower parts of the latches 9 with an already thickened edge 4, and finally the holes cut out 10, which remain in the material strip after the lower parts of the clasps are cut out. 8 shows a plan view of a part of the strip according to Fig. 7.
