Vim li cas Gr5 Ti-6Al-4V nyiam dua cov ntshiab titanium Gr1 / Gr2 rau kub spinning plhaub?
Cov laj thawj yog raws li nram no:
1. Lub siab -kub kev ua haujlwm zoo ntawm Gr5 yog sib xws nrog cov txheej txheem kub spinning. Nws yog ib qho + titanium alloy, qhia cov yas zoo nyob rau hauv 600-850℃kub spinning kub ntau yam. Tsis tas li ntawd, nws lub zog kub kub yog ntau dua li cov ntshiab titanium. Ntshiab titanium (Gr1 / Gr2) yog qhov ua rau softening ntawm qhov kub thiab txias, ua rau tsis txaus rigidity ntawm spun plhaub tom qab ua tiav;
Gr5 Cheebtsam tom qab tsim muaj lub zog ntau dua thiab nkag mus, thiab cov khoom tiav feem ntau yog siv rau siab-cov kabmob plhaub, aerospace, thiab cov khoom siv nqus tsev vacuum.
2. Lub qhov rais sib sau yog dav, thiab cov txheej txheem ruaj khov yog muaj zog. Titanium alloy kub spinning yog rhiab rau kub, pub tus nqi, thiab rotational ceev. Gr5 mature txheej txheem tiav lawm, thiab nws yuav tsis tshua muaj cov kab nrib pleb lossis cov phab ntsa tsis sib xws. Cov txheej txheem spinning nyob rau hauv ob qho tib si domestic thiab txawv teb chaws factories yog feem ntau haum rau Gr5 blanks.
3. Lub teeb yuag + Lub zog muaj zog sib npaug Raws li qhov loj me, lub zog tensile ntawm Gr5 Cheebtsam yog ntau tshaj li ob npaug ntawm cov titanium ntshiab, ua tau raws li qhov yuav tsum tau ua kom txo qhov hnyav thiab siab tsis kam ntawm nyias -walled rotating qhov chaw. Nws yog cov khoom siv tseem ceeb rau spinning qhov chaw hauv aviation, lub zog, thiab lub tshuab nqus tsev.
4. Tus nqi thiab kev ua tau zoo Balance Point Piv nrog rau qib siab -qib titanium alloys (xws li Ti-6242, Ti5553, thiab lwm yam), cov khoom siv raw ntawm Gr5 yog nruab nrab thiab cov khoom siv ntawm cov billets txaus, ua rau nws tsim nyog rau batch kub spinning ntau lawm.
Daim Ntawv Thov Scenario: Nyias-cov thooj voos kheej kheej phab ntsa, lub plhaub conical, lub taub hau, thiab cov khoom sib hloov ntawm lub tshuab nqus tsev.
Vim li cas thiaj yuav tsum tau lub ntsej muag ntawm titanium puag ncig cov kua qaub- ntxuav?
Cov ntaub ntawv kub spinning dawb paug, lawv puas tuaj yeem kub - dov nrog cov tawv nqaij dub lossis raug kho los ntawm sandblasting?
1) Kub- dov dub tawv (tsis muaj pickling) - Kev phom sij loj: Oxide txheej yog nias rau hauv qhov chaw ua haujlwm. Thaum lub sij hawm kub dov, titanium alloy nto tsim ib qho nyuaj TiO₂ oxide txheej (oxygen- nplua nuj txheej). Thaum lub sij hawm kub spinning txheej txheem, cov chais siv zog siab, ua rau cov oxide txheej yuav tsum nias rau hauv lub hauv paus hlau, uas ua rau:
• Nto pockmarks, kev nyuaj siab, thiab interlayers;
• Cov teeb meem tshwm sim thaum lub sij hawm tom qab machining thiab nrhiav pom qhov tsis zoo, ua rau kev khawb ncaj qha;
• Cov txheej oxide muaj cov pa oxygen siab, ua rau cov khoom siv hauv zos brittleness, thiab microcracks raug tsim thaum lub sij hawm spinning.
2) Kev ua haujlwm ntawm cov txheej txheem ntxuav cov kua qaub: Acid ntxuav tuaj yeem tshem tawm tag nrho: txheej txheej oxide, cov pa oxygen - nplua nuj txheej los ntawm huab cua nqus, cov roj av stains thiab dov plua plav, ua rau matte, huv si, nyiaj - grey nto.
Cov ntsiab lus ntawm cov pa oxygen ntawm lub hauv paus saum npoo yog sib xws, tsis txhob muaj cov brittleness hauv zos;
Tsis muaj ib qho nyuaj, thiab cov txheej txheem spinning yuav tsis ua rau saum npoo indentation lossis embedded defects.
Vim li cas nws tsis pom zoo kom siv sandblasted nto blanks?
Sandblasting yuav ua kom txias - ua haujlwm hardening txheej ntawm titanium nto, ua rau muaj kev ntxhov siab nyob rau saum npoo; thaum lub sij hawm siab -kub kub spinning txheej txheem, nto micro- tawg yog heev nquag tshwm sim. Nyob rau tib lub sijhawm, cov xuab zeb uas seem ntawm cov xuab zeb blasting kuj tau yooj yim nias rau hauv lub workpiece thaum lub sij hawm spinning.
Ntxiv qhov zoo ntawm cov kua qaub- ntxuav Gr5 titanium puag ncig cov ntawv rau kub stamping
1. Lub xeev kev sib txhuam yog ruaj khov, txhim kho qhov sib xws thiab kev huv ntawm cov txheej txheem spun rau ntawm cov kua qaub- ntxuav. Kev sib txhuam quab yuam yog ruaj khov, thiab kev tswj xyuas qhov tseeb ntawm spun phab ntsa thickness yog siab dua; txo deg tearing los ntawm kev sib txhuam ntawm cov chais thiab cov khoom siv raw.
2. Nws yog qhov yooj yim rau cov neeg siv khoom los ua qhov tsis yog - kev kuaj kev puas tsuaj nyob rau theem pib yam tsis muaj kev cuam tshuam los ntawm cov nplai oxide, ua kom yooj yim rau kev kuaj xyuas cov kab nrib pleb thiab cov voids hauv cov khoom siv raw los ntawm kev kuaj ultrasonic thiab kev ntsuam xyuas qhov tob ntawm cov khoom tuaj.
3. Cov txheej txheem kub ntawm - qhov kub thiab txias tsis ua rau cov pa oxygen ntxiv rau hauv cov oxide - cov ntaub ntawv tsis pub dawb. Thaum raug rau tib lub sij hawm cua sov, muaj tsawg dua tshiab oxide tsim, txo qhov kev pheej hmoo ntawm cov khoom nto embrittlement vim nqus cov pa.
