Analysis Of Complex Forging Tsarin

Don titanium alloy ƙirƙira, saboda tsadar kayan aiki, ya fi dacewa da ƙirƙira, wanda ba wai kawai inganta ingancin kayan ciki ba, har ma yana adana ƙarfe. kayan aikin inji. Kowane fanni na jabu yana rinjayar ingancin ciki ko ingancin siffa na jabun fiye ko žasa. Don haka, kowane tsari dole ne a kammala shi daidai da tsarin ƙirƙira.

Ƙirƙirar (mirgina) sanduna don ƙirƙira gami da titanium, saman yana da Layer na α mai ƙarfi da gaggautsa. Kafin ya mutu ƙirƙira, ana buƙatar cire Layer ɗin don guje wa fashe saman billet ɗin yayin ƙirƙira. Don sanduna tare da diamita na ƙasa da 50 mm, ya kamata a cire saman Layer na 3 mm lokacin farin ciki. Lokacin da diamita ya fi girma fiye da 50 mm, ya kamata a cire 5 mm. Domin extruded sanduna, diamita ne kasa da 50mm, mota iya tafi 2mm, diamita ne fiye da 50mm, general mota tafi zuwa 3mm. Bayan juyawa, idan har yanzu akwai lahani a cikin sassa daban-daban, ana iya cire shi ta hanyar niƙa na gida, kuma zurfin niƙa bai kamata ya wuce 0.5mm ba.
Girman alloy ɗin titanium na ƙirƙira na ƙirƙira ana iya yanke shi akan injin zaƙi, lathe, injin yankan anode, injin ƙwanƙwasa, abin yankan dabaran niƙa ko akan guduma mai ƙirƙira ko latsa ruwa. Sakamakon yankan shine mafi girma akan na'ura mai naushi.

• (1) Kauri na madauwari saw ruwa yana tsakanin 2 zuwa 8 mm, wanda ya dace da yanke sandar tare da diamita mafi girma. Matsakaicin madaidaicin sawn madauwari yana kusan 30,000 zuwa 35,000 mm / min, kuma ana iya samun fuskar ƙarshen mai tsabta tare da ƙaramin adadin abinci. Don hana kayan aikin haɗin ƙarfe, ƙone ƙarfe, yi amfani da dakatarwa don rage juzu'i da sanyaya kayan aikin.
• (2) Anode-yanke titanium gami anode inji yankan, da tsaga nisa ne ba fiye da 3 mm, da kuma ruwa gilashin da taro na 1.28-1.32 g / cm3 da ake amfani da matsayin aiki ruwa. Ko da yake yankan anode yana da ƙarancin yankan farashi, ƙarancin ƙimar yana da ƙasa.
• (3) Kafin yanke da yanke a kan guduma ko latsawa na ruwa, kayan mashaya ya kamata a preheated zuwa yanayin fara nakasawa don naushi (ko yankan). Za a iya yanke titanium mai tsabta na masana'antu sanyi akan injin buga naushi.
• (4) A lokacin da yankan da titanium gami a kan lathe, da yankan gudun ya kamata a cikin 25000 ~ 30000mm / min, da kuma yankan adadin ne 0.2 ~ 0.3mm / mako.
• Lokacin da aka cire ɓawon burodi daga layin alpha, ƙayyadaddun ƙayyadaddun ƙirar mota shine: ƙimar yankan 15000 zuwa 20000 mm / min. Ƙayyadaddun ƙayyadaddun juzu'i ba tare da ƙirar alpha ba yana da alaƙa da rashin ƙarfi na ƙasa: lokacin da roughness Ra shine 0.63 zuwa 2.5, adadin ciyarwa shine 0.08 zuwa 0.1 mm / mako; lokacin da Ra = 1.25 zuwa 5, adadin abincin shine 0.1 zuwa 0.2 mm / Week; lokacin da Ra = 2.5 zuwa 10, adadin abinci shine 0.3 zuwa 0.4 mm / mako. Dole ne a yi amfani da mai sanyaya mai sanyaya don juyawa kuma a kawo shi a matsa lamba na 1 zuwa 1.5 MPa.
• (5) Lokacin da diamita na titanium alloy mashaya bai wuce 60mm ba, sai a yanke shi da dabaran niƙa. Lokacin da diamita na dabaran niƙa ya fi 20 mm, ya kamata a yi amfani da mai sanyaya. Dabarar niƙa tana da babban aikin yankan, amma dabaran niƙa tana da ɗan gajeren rayuwa.

Bayan an yanke blank ɗin, ya kamata a zagaye babban kusurwar ƙarshen. In ba haka ba, yana iya haifar da nadawa yayin aiwatar da ƙirƙirar fuskar mutuƙar ƙirƙira ko yin sama a kan injin ƙirƙira a kwance. Wurin da ba komai yana da diamita na ƙasa da 50 mm yana da radius mai zagaye R na 1.5 zuwa 2.0 mm; Wurin da ke da diamita fiye da 50 mm yana da radius mai zagaye R na 3 zuwa 4 mm.
Ana yin gwajin ultrasonic bayan ƙera sassa masu mahimmanci (kamar vanes), sanduna ko zagaye masu girma don bayyana lahani na ciki.
