Matsalolin Mashin ɗin Titanium
Thermal conductivity na titanium gami karami ne, don haka yankan zafin jiki ne sosai high lokacin sarrafa titanium gami. A karkashin irin wannan yanayi, yankan zafin jiki na sarrafa TC4[i] ya ninka fiye da na No. 45 karfe, kuma zafi da aka haifar a lokacin sarrafawa yana da wuyar wucewa ta wurin aiki. Saki; ƙayyadaddun zafi na alloy na titanium ƙananan ne, kuma yawan zafin jiki na gida yana tashi da sauri yayin aiki. Sabili da haka, yawan zafin jiki na kayan aiki yana da girma sosai, kayan aiki na kayan aiki yana sawa sosai, kuma an rage rayuwar sabis.
The low na roba modulus na titanium gami[ii] sa machined surface yiwuwa ga springback, musamman machining na bakin ciki-banga sassa ne mafi tsanani, wanda shi ne mai sauki haifar da karfi gogayya tsakanin flank da machined surface, game da shi sanye da kayan aiki da kuma. chipping. ruwa.
Titanium alloy yana da aikin sinadarai mai ƙarfi, kuma yana da sauƙin mu'amala da iskar oxygen, hydrogen da nitrogen a yanayin zafi mai yawa, wanda ke ƙara ƙarfinsa kuma yana rage filastik. Layin mai wadataccen iskar oxygen da aka samar yayin dumama da ƙirƙira yana sa yin aiki da wahala.
Ka'idodin injina na kayan gami na titanium[1-3]
A cikin tsarin aikin injiniya, kayan aikin da aka zaɓa, yanayin yankewa da yanke lokaci zai shafi tasiri da tattalin arziki na yankan alloy titanium.
1. Zaɓi kayan aiki mai ma'ana
Bisa ga kaddarorin, hanyoyin sarrafawa da kuma sarrafa yanayin fasaha na kayan haɗin gwal na titanium, kayan aikin kayan aiki ya kamata a zaba da kyau. Ya kamata a zaɓi kayan aikin da aka fi amfani da su, ƙarancin farashi, juriya mai kyau, ƙarfin zafi mai ƙarfi, kuma yana da isasshen ƙarfi.
2. Inganta yanayin yanke
Rigidity na tsarin injin-kayyade-kayan aiki ya fi kyau. Ya kamata a daidaita share kowane bangare na kayan aikin injin da kyau, kuma radial runout na spindle ya zama ƙarami. Ayyukan ƙuƙuwa na ƙayyadaddun ya kamata ya kasance mai ƙarfi da ƙarfi sosai. Sashin yanke kayan aiki ya kamata ya zama takaice kamar yadda zai yiwu, kuma ya kamata a kara yawan kauri na yankan kamar yadda zai yiwu lokacin da juriyar guntu ya isa don inganta ƙarfin da ƙarfin kayan aiki.
3. Maganin zafi mai dacewa na kayan da aka sarrafa
Ana canza kaddarorin da tsarin ƙirar ƙarfe na kayan gami na titanium ta hanyar magani mai zafi [iii], don haɓaka ƙirar kayan.
4. Zaɓi adadin yankan da ya dace
Gudun yanke ya kamata ya zama ƙasa. Saboda saurin yankan yana da tasiri mai girma akan zafin jiki na yankan, mafi girman saurin yankewa, haɓakar haɓakar zafin jiki na yankan, kuma zafin jiki na yanke kai tsaye yana shafar rayuwar kayan aiki, don haka wajibi ne don zaɓar saurin yankan da ya dace.
