Description

Polaczenie ogniw nozyc wiertniczych przy urzadzeniach do glebokiego wiercenia zapomoca rozcinania jednego albo oby¬ dwóch ramion nozyc i spawania miejsca przeciecia po zawieszeniu ramion nozyc ma te wade, ze wykonane w ten sposób no¬ zyce ogniwowe posiadaja sklonnosc zry¬ wania sie w miejscu spawania, przez co moga powstac przerwy w ruchu brzemien¬ ne w nastepstwa.Wobec tego zaczeto odkuwac cale no¬ zyce ogniwowe z jednego kawalka w for¬ mach kowalskich a oddzielenie obu ogniw nozyc uzyskiwano przez usuniecie mate- rjalu pozostalego pomiedzy ramionami ogniwa zapomoca gryzu albo przecinano palnikiem.Ale równiez i ten sposób wykonania posiada te wade, ze w nim narazone jest ramie ogniwa na najwieksze naprezenia przy ciagnieniu i nie otrzymuje budowy materjalu o potrzebnej wysokiej rozciagli¬ wosci, poniewaz ten sposób wykonania nie pozwala na zgeszczenie materjalu w miej¬ scu, o które chodzi.Przedmiotem wynalazku niniejszego jest sposób wykonania wiertniczych nozyc ogniwowych z jednego kawalka, w którym ramiona ogniwa poddaje sie kuciu dla specjalnego zgeszczenia, a to w celu osia¬ gniecia budowy materjalu o wyzszej roz¬ ciagliwosci.W tym celu, jak to uwidoczniono na fig. 1, ramiona obydwóch ogniw nozyc zo¬ staja wygiete kablakowato i wytloczone w formach kowalskich umieszczonych w plaszczyznie, przyczem jednoczesnie zo¬ staja odkute i obrobione slizgajace siejedno w drugiem ogniwa nozyc. Poczem miejsca skrzyzowania ramion 1 i 2 zosta¬ ja rozdzielone w sposób mechaniczny.Teraz ogniwa nozyc w ksztalcie lan¬ cucha polaczone jedno z drugiem zostaja obrócone prostopadle i wykonczone osta¬ tecznie. Fig. 2 uwidacznia ksztalt, a fig. 3 — przekrój, jaki przybiera polówka no¬ zyc wedlug tego sposobu wykonania. PL PLThe linkage of the drilling scissors on deep drilling machines by cutting one or both of the scissor arms and welding the cutting point after hanging the scissors arms has the disadvantage that the cell scissors produced in this way tend to break at the point of welding, due to which may result in breaks in the movement, which may result in heavy repercussions. Therefore, whole link cutters were broken from one piece in blacksmith forms, and the separation of the two links of the cutters was achieved by removing the material remaining between the arms of the cutter link or cut with a torch. But also this method of production has the disadvantage that in it the link frame is exposed to the highest stresses under tension and does not receive the material structure with the necessary high elongation, because this method of production does not allow the material to compress in the place where The subject of the present invention is a method of making a one-piece drill link A table in which the arms of the link are forged for a special crimp in order to achieve a material construction with a higher stretch. For this purpose, as shown in Fig. 1, the arms of both links of the scissors are cantilevered and embossed in blacksmith forms placed in the plane, while at the same time they are forged and processed, sliding one line into the other link of the scissors. Then the crossing points of the arms 1 and 2 were separated mechanically. Now the links of the chain-shaped scissors connected to one another are turned perpendicularly and finally finished. Fig. 2 shows the shape, and Fig. 3 shows the cross section that the half of the scissors take according to this embodiment. PL PL
