Przedmiot wynalazku niniejszego stano¬ wi sposób laczenia zie soba dowolnych zer¬ dzin hub pretów.Sposób ten nadaje sie wtenczas gdy chodzi o pewne polaczenie zerdzin z glów¬ ka, a zwlaszcza wykonanych z zelaza uszla¬ chetnionego domieszkami, zastosowanie ma glównie do zerdzin wiertniczych.Przy .glebokich wierceniach sposobem udarowym wazna role odgrywaja zerdziny wiertnicze, na których wisi warsztat wiert¬ niczy, skladajacy sie z dlóta, obciaznika, nozyc i lacznika.Dotychczas, laczono zerdziny z glówka zapomoca zgrzewania (spawania), co ma pewne niedogodnosci. Najwieksza ilosc zry¬ wania zerdzin przypada badzto w samem miejscu zgrzewania, badz w najblizszej je¬ go okolicy, a to z powodu przegrzewania tworzywa podczas spawania. Nastepnie przy laczeniu sposobem zgrzewania na zer- dzinie daje sie stosowac tylko zelazo o ni¬ skiej zawartosci wegla, a tern samem o ma¬ lej wytrzymalosci (35—40 kg/mm), nato¬ miast zelaza i stali o wiekszej zawartosci wegla, jak równiez zawierajacego inne do¬ mieszki uszlachetniajace, w rodzaju niklu, chromu i manganu nie mozna uzywac na zerdziny, albowiem ogrzewanie ich jest al¬ bo niemozliwe, albo pod wzgledem wy¬ trzymalosci niepewne. Z drugiej strony ze wzgledu na to, ze zuzycie zerdzin polega na przemianie budowy zelaza z postaci wlóknistej na postac .ziarnista, wywolywa¬ nej ciaglemi wstrzajsliieniami przy wierce¬ niu udarowem, a domieszki wymienionychmaterjalów uszlachetniajacych znakomicie moglyby podniesc ich wytrzymalosc, poza- danyby byl taki sposób laczenia konców zerdzin, któryby usuwal koniecznosc zgrze¬ wania, Proponowany sposób laczenia konców zerdzin uwidocznia tytulem przykladu ryi-' sunek, na którym fig. 1 daje widok ogólny zerdziny wiertniczej, zlozonej z zerdzi, po¬ laczonej z glówkami, fig. 2—szczegól wy¬ konania w przekroju przed polaczeniem/ fig. 3—widok koncowy jednego konca zer¬ dziny i fig. 4—takiz jak na fig. 2 przekrój po polaczeniu z zerdlzina.Sposób polega na tern, ze wi koncach lacznikowych zerdzi 1 wykonane jest gnia¬ zdo 2, a zerdz 3 na koncu sie zbija w jaki¬ kolwiek sposób i na taki zgrubiany koniec 4 z wyzlabionemi w nita rowkami 5 luib bez nich wsuwa sie gniazdo 2 nagrzanego* konca lf które nastepnie zaciskane jest pod prasa, mlotem lub w jakikolwiek inny spo¬ sób. PLThe subject of the present invention is a method of joining together any of the nuclei of the hub rods. This method is suitable when it comes to a certain combination of nuclei from the head, especially those made of iron enriched with admixtures, it is mainly applicable to drilling nuclei. In deep hammer drilling an important role is played by drill rods on which a drill workshop hangs, consisting of a chisel, a weight, scissors and a fastener. Until now, welding rods have been connected to the head by welding, which has some drawbacks. The greatest number of ruptures occurs at the very spot of welding, or in its closest vicinity, due to overheating of the material during welding. Then, when joining by means of zero-carbon welding, it is possible to use only iron with a low carbon content, and the same with low strength (35-40 kg / mm), while iron and steel with a higher carbon content, such as Also containing other additives, such as nickel, chromium and manganese, it cannot be used in the production of zerdzin because their heating is either impossible or their strength is uncertain. On the other hand, due to the fact that the wear of zerdzin consists in the transformation of the structure of iron from a fibrous form into a grainy form, caused by continuous shocks during impact drilling, and the admixtures of the abovementioned materials would be an excellent addition to the method of joining the ends of the zerdzines, which would eliminate the necessity of welding, detail of the embodiment in the cross section before joining (Fig. 3 - end view of one end of the zero line and Fig. 4 - as in Fig. 2, the cross section after joining with the zero line. socket 2, and nip 3 at the end is knocked in any way, and on such a thickened end 4 with 5 or without grooves in rivets, the socket 2 of the heated end is inserted 1f which is then clamped under a press, hammer or in any other way.
